We recommend using MGcount*, a counting tool developed at Diagenode with a suitable annotations file that include the small RNA transcripts that are object of study. MGcount, built on top of featureCounts, employs a flexible quantification approach to deal with datasets containing multiple RNA biotypes such as D-plex libraries. Non-coding RNAs varying in length, biogenesis, and function, may overlap in a genomic region, and are sometimes present in the genome with a high copy number. Consequently, reads may align equally well to more than one position in the reference genome or/and align to a position where more than one annotated transcript is located. MGcount employs two strategies to quantify these reads. Firstly, it assigns reads in rounds prioritizing small-RNAs over long-RNAs ensuring the unbiased read attribution to intergenic and intragenic small RNAs while preventing host-genes transcription over-estimation. Secondly, MGcount collapses loci where reads consistently multi-map into communities of loci with a graph-based approach. The resultant communities are groups of biologically related loci with nearly identical sequence. Subsequently, quantification of reads is performed at the loci-community level, reducing multi-alignments ambiguity at individual locus. Ultimately, this strategy maximizes the transcriptome information analysed and improves the interrogation of non-coding RNAs. MGcount software repository provides annotation files for A. thaliana, H. sapiens, M. musculus and C. elegans. The required input files for MGcount are a .txt file listing the paths to the alignment input files (.bam format) and the annotations file (.gtf format). The output directory path has to be provided as an input as well.</p> <p><strong>Example command:</strong></p> <p style="background-color: #f0f0f0;">MGcount -T 2 --gtf Homo_sapiens.GRCh38.gtf --outdir outputs --bam_infiles input_bamfilenames.txt</p> <p>MGcount provides the choice to enable/disable the quantification of all RNA biotypes included in the annotation file in the form of "communities" as optional parameters for small-RNA (--ml_flag_small) and long-RNA (--ml_flag_long). Both are enabled by default. The main output of MGcount is the count_matrix.csv file containing an expression matrix that can be imported to R or any other software for downstream analyses.<br />A full user guide for MGCount is available here: <a href="https://filedn.com/lTnUWxFTA93JTyX3Hvbdn2h/mgcount/UserGuide.html">https://filedn.com/lTnUWxFTA93JTyX3Hvbdn2h/mgcount/UserGuide.html</a>.</p> <p>Other standard counting tools such as featureCounts or HTSeq-counts can also be used alternatively. Given the high complexity of D-Plex libraries, we recommend having a clear understanding of the scientific question and the goal of the project before proceeding to the choice of the counting method as this will strongly impact downstream analyses. Diagenode provides bioinformatics support as a service (please, contact us if you need help with data analysis).</p> <p>Notice that D-Plex produces forward-stranded data. Stranded libraries have the benefit that reads map to the genome strand where they were originated from. Therefore, when estimating transcript expression, reads aligned to the forward strand should be assigned only to transcript features in the forward strand whereas reads aligned to the reverse strand should be assigned only to transcript features in the reverse strand. For this, make sure you select “stranded mode” in any tool of choice. Stranded mode is selected by default in MGcount.</p> <p><em><small>*Hita, A., Brocart, G., Fernandez, A. et al.

However, molecular events in end-organ diseases such as central nervous system (CNS) disease are not yet fully understood, and routine eradication of latent reservoirs is not yet in reach. Extracellular vesicle (EV) RNAs have emerged as important participants in HIV disease pathogenesis. Brain tissue-derived EVs (bdEVs) act locally in the source tissue and may indicate molecular mechanisms in HIV CNS pathology. Using brain tissue and bdEVs from the simian immunodeficiency virus (SIV) model of HIV disease, we profiled messenger RNAs (mRNAs), microRNAs (miRNAs), and circular RNAs (circRNAs), seeking to identify possible networks of RNA interaction in SIV infection and neuroinflammation. Methods: Postmortem occipital cortex tissues were obtained from pigtailed macaques either not infected or dual-inoculated with SIV swarm B670 and clone SIV/17E-Fr. SIV-inoculated groups included samples collected at different time points during acute infection or chronic infection without or with CNS pathology (CP- or CP+). bdEVs were separated and characterized in accordance with international consensus standards. RNAs from bdEVs and source tissue were used for sequencing and qPCR to detect mRNA, miRNA, and circRNA levels. Results: Multiple dysregulated bdEV RNAs, including mRNAs, miRNAs, and circRNAs, were identified in acute and CP+. Most dysregulated mRNAs in bdEVs reflected dysregulation in their source tissues. These mRNAs are disproportionately involved in inflammation and immune responses, especially interferon pathways. For miRNAs, qPCR assays confirmed differential abundance of miR-19a-3p, let-7a-5p, and miR-29a-3p (acute phase), and miR-146a-5p and miR-449a-5p (CP+) in bdEVs. In addition, target prediction suggested that several circRNAs that were differentially abundant in source tissue might be responsible for specific differences in small RNA levels in bdEVs during SIV infection. RNA profiling of bdEVs and source tissues reveals potential regulatory networks in SIV infection and SIV- related CNS pathology.</p>', 'date' => '2023-04-01', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/37034720', 'doi' => '10.1101/2023.04.01.535193', 'modified' => '2023-06-12 09:04:45', 'created' => '2023-05-05 12:34:24', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 1 => array( 'id' => '4375', 'name' => 'Neutral sphingomyelinase 2 inhibition attenuates extracellular vesiclerelease and improves neurobehavioral deficits in murine HIV.', 'authors' => 'Zhu X. et al.', 'description' => '<p>People living with HIV (PLH) have significantly higher rates of cognitive impairment (CI) and major depressive disorder (MDD) versus the general population.

However, disruption of epigenetic mechanisms may alter gene function, potentially leading to cellular transformations that lead to tumorigenesis. Cancer is a multistep process from a succession of processes that alter the growth of normal cells. In cancer, epigenetic reprogramming occurs at multiple levels including nuclear organization and nucleosome positioning, DNA methylation, modification of histones, alteration of epigenetic regulators such as transcription factor binding, and non-coding RNA, such as microRNA.</p> <p>Epigenetic modifications are reversible and potential treatments could be geared to alter irregular transcription factor binding, DNA methylation or histone acetylation. Accurate study with a versatile number of tools is essential for the study of epigenetics including sound sample preparation and analysis methodologies for DNA methylation such as with immunoprecipitation or bisulfite sequencing, chromatin analysis with chromatin immunoprecipitation (ChIP) combined with qPCR or sequencing, and RNA modification study. As researchers elucidate the mechanisms and specific modifications associated with cancer, it may be possible to target abnormal modifications in cells with minimal damage to normal cells, making the prospect of epigenetic therapy increasingly promising.</p> <h3>Diagenode products for your epigenomics research in Cancer</h3> <div class="row"> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #099f92; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/chromatin-function">Chromatin analysis</a></h3> <center><a href="https://www.diagenode.com/en/categories/chromatin-function"><img src="https://www.diagenode.com/img/cancer/chromatin-icon.png" /></a></center> <p class="text-left">Understand the role of chromatin in cancer regulation</p> </div> <ul> <li>New to ChIP? <a href="https://www.diagenode.com/en/pages/portal/chip">Learn more</a></li> <li><a href="https://www.diagenode.com/en/categories/chromatin-shearing">Chromatin shearing optimization</a></li> <li><a href="https://www.diagenode.com/en/categories/chromatin-immunoprecipitation">Chromatin Immunoprecipitation</a></li> <li>Validated <a href="https://www.diagenode.com/en/categories/antibodies">Antibodies</a></li> <li><a href="https://www.diagenode.com/en/categories/library-preparation">Library preparation</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #30415c; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/dna-methylation" style="color: #30415c;">DNA methylation</a></h3> <center><a href="https://www.diagenode.com/en/categories/dna-methylation"><img src="https://www.diagenode.com/img/cancer/dna-icon.png" /></a></center> <p class="text-left">Analyze DNA methylation and the effects on oncogenesis and tumor suppression</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/bisulfite-conversion">Bisulfite sequencing</a></li> <li><a href="https://www.diagenode.com/en/categories/methylated-dna-immunoprecipitation">Methylated DNA immunoprecipitation</a></li> <li><a href="https://www.diagenode.com/en/categories/dna-methylation-profiling-services">DNA methylation services</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #474546; height: 275px;"> <h3 class="text-center"><span class="darkgrey">Non-coding RNAs</span></h3> <center><img src="https://www.diagenode.com/img/cancer/non-coding-icon.png" /></center> <p class="text-left">Discover noncoding RNAs in cancer</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/Library-preparation-for-RNA-seq">RNA-seq using D-Plex</a> </li> <li><a href="https://www.diagenode.com/en/categories/rna-seq-category">RNA-seq services</a></li> </ul> </div> </div> <div id="ConnectiveDocSignExtentionInstalled" data-extension-version="1.0.4"></div> <div id="ConnectiveDocSignExtentionInstalled" data-extension-version="1.0.4"></div>', 'online' => true, 'in_menu' => true, 'slug' => 'cancer', 'cookies_tag_id' => null, 'meta_title' => 'cancer', 'meta_description' => 'cancer', 'meta_keywords' => 'cancer', 'modified' => '2022-11-24 13:21:38', 'created' => '2018-08-03 15:56:34', 'ProductsArea' => array( [maximum depth reached] ) ), (int) 2 => array( 'id' => '3', 'parent_id' => null, 'name' => 'Neuroscience', 'description' => '<div class="extra-spaced"> <p><img src="https://www.diagenode.com/img/areas/neuroscience.jpg" /></p> </div> <h2>Epigenetics in Neuroscience</h2> <p>Neuroscience and epigenetics are at an exciting crossroads. Current research has shown that epigenetic mechanisms play a critical role in both behavior and the development and function of the nervous system. Histone modifications, changes in DNA methylation, and non-coding RNAs regulate various stages of neurogenesis and brain development while aberrant epigenetic regulation has been implicated in a number of neurological and brain disorders (Yao et, al. Nature Reviews Neuroscience, 2016).</p> <p>Neuroscientists seek to uncover how epigenetic marks and transcriptional changes regulate gene expression to influence changes in areas such as behavior and the development of neural pathways and brain structures. Understanding how epigenetics affects nervous system function requires an integrative approach incorporating multiple levels of analysis. For example, research has uncovered the role of transcription factors, non-coding RNAs, and other molecules that mediate learning and memory. In addition, chromatin modifications and non-coding RNAs have been shown to influence epigenetic mechanisms in neurogenesis.</p> <p>Understanding the molecular components and environmental conditions that affect epigenetic change will eventually provide the basis to develop therapies to treat neurological and psychiatric conditions. As neuroscientists learn how changes in chromatin architecture affect transcriptional regulation and gene expression, the link between the epigenome and the various areas in neuroscience will become clearer.</p> <h3><span class="diacol">Neuroscience and epigenetics intersect in a number of areas: </span></h3> <ul class="accordion" data-accordion=""> <li class="accordion-navigation"><a href="#memory"> <i class="fa fa-square-o"></i> Epigenetics in memory, memory disorders, and learning</a> <div id="memory" class="content"> <blockquote><br /> <p><strong>Epigenetic mechanisms underlying learning and the inheritance of learned behaviors</strong></p> <p>In this review, researchers outline epigenetic mechanisms by which gene expression is regulated in animals and humans.

Environmental factors such as dietary intake, drugs, stress, or exposure to toxins, can cause epigenetic changes by possibly altering how transcription factors bind to DNA or changing the structure of the histones that DNA wraps around. These structural changes can affect gene activity or gene expression. A number of environmental factors have been investigated for their effect on epigenetic changes including phthalates, toxic metals, smoking, air pollution, jet fuel, environmental stress, and a high fat diet. Effects on epigenetic mechanisms, DNA methylation patterns, histone modifications, miRNA expression have been documented as a result. The table below (Marczylo et al, 2016 and Society of Toxicology, 2018) summarizes a few of the studies that have been done for putative environmentally-induced epigenetic toxicity in humans or rat/mouse.</p> <p class="extra-spaced">In the future, incorporating epigenetic evaluation into toxicity tests can increase the safety of both food and environmental substances.</p> <table class="extra-spaced"> <tbody> <tr> <th style="text-align: center;">Toxin/exposure</th> <th style="text-align: center;">Species/stage of exposure/effect</th> <th style="text-align: center;">Phenotype</th> <th style="text-align: center;">Epigenetic change</th> <th style="text-align: center;">Reference(s)</th> </tr> <tr> <td>Air pollution</td> <td style="text-align: center;">Human/childhood/childhood</td> <td style="text-align: center;">Asthma</td> <td style="text-align: center;">Epigenetic mechanisms</td> <td style="text-align: left;">Somineni et al.

Plants depend on changes in gene expression to respond to environmental stimuli, in which the full repertoire of histone modifications, DNA methylation, and small ncRNAs play an important role in epigenetic regulation.</p> <p>Studying the epigenetics of model plants such as Arabidopsis thaliana have allowed researchers to understand pathways that maintain chromatin modifications as well as the mapping of modifications such as DNA methylation on a genome-wide scale. Small RNAs have also been implicated in playing a role in the distribution of chromatin modifications, and RNA may also play a role in the complex epigenetic interactions that occur between homologous sequences (Moazed et al, 2009). In the future, by understanding epigenetic control, researchers can uncover the research necessary to improve plant growth, yields, and transformation efficiency especially in the face of climate change and other environmental factors.</p> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/chromatin-and-transcription-factors.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <h3 style="font-weight: 100; margin-top: 0;">Chromatin</h3> <p>Chromatin consists of nucleosomes formed by a complex of histone proteins and DNA, which allows the packaging of DNA into the nucleus. The less condensed euchromatin represents transcriptionally active regions, while heterochromatin is usually inactive (Vaillant and Paszkowski, 2007). Chromatin state is known to be influenced by both DNA methylation and histone modifications which in turn impact gene expression and the structure of chromosomes. In a recent study, the role of chromatin modifications during plant reproduction elucidated 3-dimensional chromosome reorganization mediated by histones and DNA methylation (Dukowic-Schulze et al. 2017). In addition, gibberellins have been shown in increasing the level of histone acetylation, which affects regions of chromatin involved in maize seed germination (Zheng et al. 2017). Another study reports a novel function of a tomato histone deacetylase gene in the regulation of fruit ripening (Guo et al. 2017).</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/cherry-tomato-common-grape-vine-ripening-fruit-vegetable-cherry-tomatoes.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <p>In addition, multigene families encode transcription factors, with members found throughout the genome or clustered on the same chromosome. Numerous DNA binding proteins that interact with plant promoters have been identified -- some are similar to well-characterized transcription factors in animals or yeast, while others are unique to plants. For example, diverse members of the subfamily X of the plant-specific ethylene response factor (ERF) transcription factors coordinate stress signaling with wound repair activation. Tissue repair is also enhanced through a protein complex of ERF and GRAS TFs (Heyman et. al,.2018). A compilation of known plant transcription factors can be found in the plant transcription factor database at http://plntfdb.bio.uni-potsdam.de/v3.0/.</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/rna-strand.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <h3 style="font-weight: 100; margin-top: 0;">RNA</h3> <p>Recent research shows that a number of classes of small RNAs are key epigenetic regulators. In many cases, small RNAs have been implicated in DNA methylation and chromatin modification (Meyer, 2015). In addition, the role of small RNAs has been implicated in plant stress tolerance (Kumar et al., 2017). López-Galiano et al also provided insight into a coordinated function of a miRNA gene and histone modifications in regulating the expression of a WRKY transcription factor in response to stress.</p> <p>RNA interference (RNAi) is another epigenetic mechanism that leads to small RNA generation, which mediates gene silencing at the post-transcriptional level. RNAi technology has immense potential for plant disease resistance.</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/dna-methylation.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <h3 style="font-weight: 100; margin-top: 0;">DNA methylation</h3> <p>Plants, unlike animals, have three sites that can be methylated G, CHG (H can be A, C, T), and CHH (Law and Jacobsen, 2010). DNA methylation has attracted particular interest. In Arabidopsis, one-third of methylated genes occur in transcribed regions, and 5% of genes are methylated in promoter regions, suggesting that many of these are epigenetically regulated. (Zhang et al., 2006).</p> <p>There are thousands of differentially methylated regions (DMRs) that influence phenotype by influencing gene expression. The analysis of epigenetic recombinant inbred line (epiRIL) plants from Arabidopsis points to the evidence of the influence of DMRs. An epiRIL results from crossing two genetically identical plants with differing DNA methylation levels (with one parent as a homozygous mutant for an essential DNA methylation maintenance gene). The offspring of these plants have similar genomes that vary only in methylation levels. Many traits have been studied using epiRILs -- flowering time, plant height, and response to abiotic stress, some of which have now been mapped to DMRs (Zhang et al. 2018)</p> <p>Regulation by DNA methylation has been shown to be important in many aspects of plant development and response such as vernalization, hybrid vigor, and self-incompatibility (Itabashi et al. 2017). For example, vernalization treatments have shown reduced DNA methylation and subsequent initiation of flowering (Burn et al., 1993). Stress can also influence DNA methylation in plants as a response to environmental stimuli. (Steward et al., 2002; Song et al., 2012). A high degree of DNA methylation has also suggested the role in the improvement of plant fitness under different environmental conditions (Saéz-Laguna et al., 2014). In addition, methylation can affect normal fruit and hypomethylation predicts homeotic transformation and loss of fruit yield (Ong-Abdullah et al., 2015)</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/plant-development.jpg" class="left" style="padding-right: 15px;" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <p>DNA demethylation has also been implied in various aspects of plant development including pollen tube formation, embryogenesis, fruit ripening, stomatal development, and nodule formation ( Li et al. 2017). Demethylation of rice genomic DNA caused an altered pattern of gene expression, inducing dwarf plants (Sano et al., 1990).</p> <p>Epigenetic modifications contribute to the stability and survival of the plants and their ability to adapt in different environmental conditions.</p> </div> </div> <h3>Diagenode products for your epigenomics research in plants</h3> <div class="row extra-spaced"> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #099f92; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/chromatin-function">Chromatin analysis</a></h3> <center><a href="https://www.diagenode.com/en/categories/chromatin-function"><img src="https://www.diagenode.com/img/cancer/chromatin-icon.png" /></a></center> <p class="text-left">Understand the role of chromatin in plant function and development</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/chromatin-function">Learn about our chromatin analysis products</a></li> <li><a href="https://www.diagenode.com/en/p/universal-plant-chip-seq-kit-x24-24-rxns"> Learn about the Universal Plant ChIP Kit</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #30415c; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/dna-methylation" style="color: #30415c;">DNA methylation</a></h3> <center><a href="https://www.diagenode.com/en/categories/dna-methylation"><img src="https://www.diagenode.com/img/cancer/dna-icon.png" /></a></center> <p class="text-left">DNA methylation and demethylation and the effects on plant response and function</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/dna-methylation">Discover DNA methylation analysis solutions at any resolution</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #474546; height: 275px;"> <h3 class="text-center"><span class="darkgrey">Non-coding RNAs</span></h3> <center><img src="https://www.diagenode.com/img/cancer/non-coding-icon.png" /></center> <p class="text-left">Discover noncoding RNAs in the regulation of gene expression in plants</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/Library-preparation-for-RNA-seq">Library prep for RNA-seq studies for ncRNAs</a></li> </ul> </div> </div> <h3>References</h3> <p><small> Burn, J. et al (1993).

Immune cells depend on the expression of specific cell-surface molecules to recognize and eliminate cancer cells. However, tumor cells can take over various epigenetic mechanisms and subsequently use epigenetic silencing to shut off this crucial expression, thereby escaping the recognition from immune cells. Epigenetic modifiers can also reactivate many silenced genes such as immune checkpoints regulators that turn on immune response.</span></p> <p>As a result, in recent years, epigenetic drugs have been a topic of keen interest for clinical researchers. These drugs include promising immunomodulatory agents that may restore expression of cell-surface molecules that allow cancer cells to once again be detectable as well as other targeting agents that trigger antitumor immune responses. Epigenetic therapies, either alone or in combination with current immunotherapies, may lead to new approaches for cancer treatment.</p> <p>The idea of combination therapy for treating cancers has become especially critical. Many patients either do not respond, become resistant, or suffer toxicities from current immunotherapy treatments alone. The combination of epigenetic therapy with common immunotherapies such as interleukin-2 therapy, adoptive T-cell transfer, and immune checkpoint inhibitors, among others are just a few of the strategies being tested with various cancer types in clinical trials. Researchers have demonstrated that combining epigenetic drugs, such as the DNA methyltransferase inhibitors 5-aza-2′-deoxycytidine and guadecitabine, with immunomodulating antibodies that target CTLA-4 or the PD-1/PDL-1 immune checkpoint improves therapeutic efficacy.</p> <p>Additionally, epigenomic signatures in immune and cancer cells may be predictors of success of immunotherapy for patients. Candidate epigenetic biomarkers may improve patient classification and personalized medicine to maximize treatment success and minimize negative effects. Potential biomarkers have been identified in the literature as predictors of the cancer response to immunotherapy such as PD-L1 expression, tumor-associated antigens (TAAs), HLA expression , tumor mutational burden and neoantigen identification , mismatch repair deficiency to name a few. The epigenetic control of these events has been validated. Epigenetic biomarkers may offer additional advantages, such as revealing information about the life habits and conditions of patients, details about the origin of the tumors, predictive indicators, and therapy-monitoring indicators.</p> </div> <h3>Diagenode products for your epigenomics research in Cancer</h3> <div class="row"> <div class="small-12 medium-4 large-4 columns text-left"> <div

Epigenetic changes such as histone modifications, </span><b>DNA methylation</b><span style="font-weight: 400;">, chromatin remodeling, and non-coding RNAs function as important regulators that alter host expression patterns. These changes have important implications to the virus itself since it relies on the host cell to replicate its genetic material and continue to proliferate.

The enzyme neutral sphingomyelinase 2 (nSMase2) is involved in the biogenesis of ceramide and extracellular vesicles (EVs), both of which are dysregulated in PLH, CI, and MDD. Here we evaluated EcoHIV-infected mice for behavioral abnormalities relevant to depression and cognition deficits, and assessed the behavioral and biochemical effects of nSMase2 inhibition. Mice were infected with EcoHIV and daily treatment with either vehicle or the nSMase2 inhibitor (R)-(1-(3-(3,4-dimethoxyphenyl)-2,6-dimethylimidazo[1,2-b]pyridazin-8-yl)pyrrolidin-3-yl)-carbamate (PDDC) began 3 weeks post-infection. After 2 weeks of treatment, mice were subjected to behavior tests. EcoHIV-infected mice exhibited behavioral abnormalities relevant to MDD and CI that were reversed by PDDC treatment. EcoHIV infection significantly increased cortical brain nSMase2 activity, resulting in trend changes in sphingomyelin and ceramide levels that were normalized by PDDC treatment. EcoHIV-infected mice also exhibited increased levels of brain-derived EVs and altered microRNA cargo, including miR-183-5p, miR-200c-3p, miR-200b-3p, and miR-429-3p, known to be associated with MDD and CI; all were normalized by PDDC. In conclusion, inhibition of nSMase2 represents a possible new therapeutic strategy for the treatment of HIV-associated CI and MDD.</p>', 'date' => '2022-07-01', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/35462006', 'doi' => '10.1016/j.nbd.2022.105734', 'modified' => '2022-08-04 15:59:55', 'created' => '2022-08-04 14:55:36', 'ProductsPublication' => array( 'id' => '5972', 'product_id' => '3045', 'publication_id' => '4375' ) ) $externalLink = ' <a href="https://www.ncbi.nlm.nih.gov/pubmed/35462006" target="_blank"><i class="fa fa-external-link"></i></a>'include - APP/View/Products/view.ctp, line 755 View::_evaluate() - CORE/Cake/View/View.php, line 971 View::_render() - CORE/Cake/View/View.php, line 933 View::render() - CORE/Cake/View/View.php, line 473 Controller::render() - CORE/Cake/Controller/Controller.php, line 963 ProductsController::slug() - APP/Controller/ProductsController.php, line 1052 ReflectionMethod::invokeArgs() - [internal], line ??

We recommend using MGcount*, a counting tool developed at Diagenode with a suitable annotations file that include the small RNA transcripts that are object of study. MGcount, built on top of featureCounts, employs a flexible quantification approach to deal with datasets containing multiple RNA biotypes such as D-plex libraries. Non-coding RNAs varying in length, biogenesis, and function, may overlap in a genomic region, and are sometimes present in the genome with a high copy number. Consequently, reads may align equally well to more than one position in the reference genome or/and align to a position where more than one annotated transcript is located. MGcount employs two strategies to quantify these reads. Firstly, it assigns reads in rounds prioritizing small-RNAs over long-RNAs ensuring the unbiased read attribution to intergenic and intragenic small RNAs while preventing host-genes transcription over-estimation. Secondly, MGcount collapses loci where reads consistently multi-map into communities of loci with a graph-based approach. The resultant communities are groups of biologically related loci with nearly identical sequence. Subsequently, quantification of reads is performed at the loci-community level, reducing multi-alignments ambiguity at individual locus. Ultimately, this strategy maximizes the transcriptome information analysed and improves the interrogation of non-coding RNAs. MGcount software repository provides annotation files for A. thaliana, H. sapiens, M. musculus and C. elegans. The required input files for MGcount are a .txt file listing the paths to the alignment input files (.bam format) and the annotations file (.gtf format). The output directory path has to be provided as an input as well.</p> <p><strong>Example command:</strong></p> <p style="background-color: #f0f0f0;">MGcount -T 2 --gtf Homo_sapiens.GRCh38.gtf --outdir outputs --bam_infiles input_bamfilenames.txt</p> <p>MGcount provides the choice to enable/disable the quantification of all RNA biotypes included in the annotation file in the form of "communities" as optional parameters for small-RNA (--ml_flag_small) and long-RNA (--ml_flag_long). Both are enabled by default. The main output of MGcount is the count_matrix.csv file containing an expression matrix that can be imported to R or any other software for downstream analyses.<br />A full user guide for MGCount is available here: <a href="https://filedn.com/lTnUWxFTA93JTyX3Hvbdn2h/mgcount/UserGuide.html">https://filedn.com/lTnUWxFTA93JTyX3Hvbdn2h/mgcount/UserGuide.html</a>.</p> <p>Other standard counting tools such as featureCounts or HTSeq-counts can also be used alternatively. Given the high complexity of D-Plex libraries, we recommend having a clear understanding of the scientific question and the goal of the project before proceeding to the choice of the counting method as this will strongly impact downstream analyses. Diagenode provides bioinformatics support as a service (please, contact us if you need help with data analysis).</p> <p>Notice that D-Plex produces forward-stranded data. Stranded libraries have the benefit that reads map to the genome strand where they were originated from. Therefore, when estimating transcript expression, reads aligned to the forward strand should be assigned only to transcript features in the forward strand whereas reads aligned to the reverse strand should be assigned only to transcript features in the reverse strand.

ワークフローは、4つのヌクレオチド(それぞれ異なる蛍光色素で標識された)の組み込み、4色イメージング、色素や末端基の切断、取り込み、イメージングなどを繰り返します。フローセルは大規模な並列配列決定を受ける。 この方法により、単一蛍光標識されたヌクレオチドの制御添加によるモノヌクレオチドのエラーを回避する可能性があります。 読み取りの長さは、通常約100〜150 bpです。</p> <h3><a

However, molecular events in end-organ diseases such as central nervous system (CNS) disease are not yet fully understood, and routine eradication of latent reservoirs is not yet in reach. Extracellular vesicle (EV) RNAs have emerged as important participants in HIV disease pathogenesis. Brain tissue-derived EVs (bdEVs) act locally in the source tissue and may indicate molecular mechanisms in HIV CNS pathology. Using brain tissue and bdEVs from the simian immunodeficiency virus (SIV) model of HIV disease, we profiled messenger RNAs (mRNAs), microRNAs (miRNAs), and circular RNAs (circRNAs), seeking to identify possible networks of RNA interaction in SIV infection and neuroinflammation. Methods: Postmortem occipital cortex tissues were obtained from pigtailed macaques either not infected or dual-inoculated with SIV swarm B670 and clone SIV/17E-Fr. SIV-inoculated groups included samples collected at different time points during acute infection or chronic infection without or with CNS pathology (CP- or CP+). bdEVs were separated and characterized in accordance with international consensus standards. RNAs from bdEVs and source tissue were used for sequencing and qPCR to detect mRNA, miRNA, and circRNA levels. Results: Multiple dysregulated bdEV RNAs, including mRNAs, miRNAs, and circRNAs, were identified in acute and CP+. Most dysregulated mRNAs in bdEVs reflected dysregulation in their source tissues. These mRNAs are disproportionately involved in inflammation and immune responses, especially interferon pathways. For miRNAs, qPCR assays confirmed differential abundance of miR-19a-3p, let-7a-5p, and miR-29a-3p (acute phase), and miR-146a-5p and miR-449a-5p (CP+) in bdEVs. In addition, target prediction suggested that several circRNAs that were differentially abundant in source tissue might be responsible for specific differences in small RNA levels in bdEVs during SIV infection. RNA profiling of bdEVs and source tissues reveals potential regulatory networks in SIV infection and SIV- related CNS pathology.</p>', 'date' => '2023-04-01', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/37034720', 'doi' => '10.1101/2023.04.01.535193', 'modified' => '2023-06-12 09:04:45', 'created' => '2023-05-05 12:34:24', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 1 => array( 'id' => '4375', 'name' => 'Neutral sphingomyelinase 2 inhibition attenuates extracellular vesiclerelease and improves neurobehavioral deficits in murine HIV.', 'authors' => 'Zhu X. et al.', 'description' => '<p>People living with HIV (PLH) have significantly higher rates of cognitive impairment (CI) and major depressive disorder (MDD) versus the general population.

Here we evaluated EcoHIV-infected mice for behavioral abnormalities relevant to depression and cognition deficits, and assessed the behavioral and biochemical effects of nSMase2 inhibition.

EcoHIV infection significantly increased cortical brain nSMase2 activity, resulting in trend changes in sphingomyelin and ceramide levels that were normalized by PDDC treatment. EcoHIV-infected mice also exhibited increased levels of brain-derived EVs and altered microRNA cargo, including miR-183-5p, miR-200c-3p, miR-200b-3p, and miR-429-3p, known to be associated with MDD and CI; all were normalized by PDDC.

However, disruption of epigenetic mechanisms may alter gene function, potentially leading to cellular transformations that lead to tumorigenesis. Cancer is a multistep process from a succession of processes that alter the growth of normal cells. In cancer, epigenetic reprogramming occurs at multiple levels including nuclear organization and nucleosome positioning, DNA methylation, modification of histones, alteration of epigenetic regulators such as transcription factor binding, and non-coding RNA, such as microRNA.</p> <p>Epigenetic modifications are reversible and potential treatments could be geared to alter irregular transcription factor binding, DNA methylation or histone acetylation. Accurate study with a versatile number of tools is essential for the study of epigenetics including sound sample preparation and analysis methodologies for DNA methylation such as with immunoprecipitation or bisulfite sequencing, chromatin analysis with chromatin immunoprecipitation (ChIP) combined with qPCR or sequencing, and RNA modification study. As researchers elucidate the mechanisms and specific modifications associated with cancer, it may be possible to target abnormal modifications in cells with minimal damage to normal cells, making the prospect of epigenetic therapy increasingly promising.</p> <h3>Diagenode products for your epigenomics research in Cancer</h3> <div class="row"> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #099f92; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/chromatin-function">Chromatin analysis</a></h3> <center><a href="https://www.diagenode.com/en/categories/chromatin-function"><img src="https://www.diagenode.com/img/cancer/chromatin-icon.png" /></a></center> <p class="text-left">Understand the role of chromatin in cancer regulation</p> </div> <ul> <li>New to ChIP? <a href="https://www.diagenode.com/en/pages/portal/chip">Learn more</a></li> <li><a href="https://www.diagenode.com/en/categories/chromatin-shearing">Chromatin shearing optimization</a></li> <li><a href="https://www.diagenode.com/en/categories/chromatin-immunoprecipitation">Chromatin Immunoprecipitation</a></li> <li>Validated <a href="https://www.diagenode.com/en/categories/antibodies">Antibodies</a></li> <li><a href="https://www.diagenode.com/en/categories/library-preparation">Library preparation</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #30415c; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/dna-methylation" style="color: #30415c;">DNA methylation</a></h3> <center><a href="https://www.diagenode.com/en/categories/dna-methylation"><img src="https://www.diagenode.com/img/cancer/dna-icon.png" /></a></center> <p class="text-left">Analyze DNA methylation and the effects on oncogenesis and tumor suppression</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/bisulfite-conversion">Bisulfite sequencing</a></li> <li><a href="https://www.diagenode.com/en/categories/methylated-dna-immunoprecipitation">Methylated DNA immunoprecipitation</a></li> <li><a href="https://www.diagenode.com/en/categories/dna-methylation-profiling-services">DNA methylation services</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #474546; height: 275px;"> <h3 class="text-center"><span class="darkgrey">Non-coding RNAs</span></h3> <center><img src="https://www.diagenode.com/img/cancer/non-coding-icon.png" /></center> <p class="text-left">Discover noncoding RNAs in cancer</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/Library-preparation-for-RNA-seq">RNA-seq using D-Plex</a> </li> <li><a href="https://www.diagenode.com/en/categories/rna-seq-category">RNA-seq services</a></li> </ul> </div> </div> <div id="ConnectiveDocSignExtentionInstalled" data-extension-version="1.0.4"></div> <div id="ConnectiveDocSignExtentionInstalled" data-extension-version="1.0.4"></div>', 'online' => true, 'in_menu' => true, 'slug' => 'cancer', 'cookies_tag_id' => null, 'meta_title' => 'cancer', 'meta_description' => 'cancer', 'meta_keywords' => 'cancer', 'modified' => '2022-11-24 13:21:38', 'created' => '2018-08-03 15:56:34', 'ProductsArea' => array( [maximum depth reached] ) ), (int) 2 => array( 'id' => '3', 'parent_id' => null, 'name' => 'Neuroscience', 'description' => '<div class="extra-spaced"> <p><img src="https://www.diagenode.com/img/areas/neuroscience.jpg" /></p> </div> <h2>Epigenetics in Neuroscience</h2> <p>Neuroscience and epigenetics are at an exciting crossroads. Current research has shown that epigenetic mechanisms play a critical role in both behavior and the development and function of the nervous system. Histone modifications, changes in DNA methylation, and non-coding RNAs regulate various stages of neurogenesis and brain development while aberrant epigenetic regulation has been implicated in a number of neurological and brain disorders (Yao et, al. Nature Reviews Neuroscience, 2016).</p> <p>Neuroscientists seek to uncover how epigenetic marks and transcriptional changes regulate gene expression to influence changes in areas such as behavior and the development of neural pathways and brain structures. Understanding how epigenetics affects nervous system function requires an integrative approach incorporating multiple levels of analysis. For example, research has uncovered the role of transcription factors, non-coding RNAs, and other molecules that mediate learning and memory. In addition, chromatin modifications and non-coding RNAs have been shown to influence epigenetic mechanisms in neurogenesis.</p> <p>Understanding the molecular components and environmental conditions that affect epigenetic change will eventually provide the basis to develop therapies to treat neurological and psychiatric conditions. As neuroscientists learn how changes in chromatin architecture affect transcriptional regulation and gene expression, the link between the epigenome and the various areas in neuroscience will become clearer.</p> <h3><span class="diacol">Neuroscience and epigenetics intersect in a number of areas: </span></h3> <ul class="accordion" data-accordion=""> <li class="accordion-navigation"><a href="#memory"> <i class="fa fa-square-o"></i> Epigenetics in memory, memory disorders, and learning</a> <div id="memory" class="content"> <blockquote><br /> <p><strong>Epigenetic mechanisms underlying learning and the inheritance of learned behaviors</strong></p> <p>In this review, researchers outline epigenetic mechanisms by which gene expression is regulated in animals and humans.

Environmental factors such as dietary intake, drugs, stress, or exposure to toxins, can cause epigenetic changes by possibly altering how transcription factors bind to DNA or changing the structure of the histones that DNA wraps around. These structural changes can affect gene activity or gene expression. A number of environmental factors have been investigated for their effect on epigenetic changes including phthalates, toxic metals, smoking, air pollution, jet fuel, environmental stress, and a high fat diet. Effects on epigenetic mechanisms, DNA methylation patterns, histone modifications, miRNA expression have been documented as a result. The table below (Marczylo et al, 2016 and Society of Toxicology, 2018) summarizes a few of the studies that have been done for putative environmentally-induced epigenetic toxicity in humans or rat/mouse.</p> <p class="extra-spaced">In the future, incorporating epigenetic evaluation into toxicity tests can increase the safety of both food and environmental substances.</p> <table class="extra-spaced"> <tbody> <tr> <th style="text-align: center;">Toxin/exposure</th> <th style="text-align: center;">Species/stage of exposure/effect</th> <th style="text-align: center;">Phenotype</th> <th style="text-align: center;">Epigenetic change</th> <th style="text-align: center;">Reference(s)</th> </tr> <tr> <td>Air pollution</td> <td style="text-align: center;">Human/childhood/childhood</td> <td style="text-align: center;">Asthma</td> <td style="text-align: center;">Epigenetic mechanisms</td> <td style="text-align: left;">Somineni et al.

Plants depend on changes in gene expression to respond to environmental stimuli, in which the full repertoire of histone modifications, DNA methylation, and small ncRNAs play an important role in epigenetic regulation.</p> <p>Studying the epigenetics of model plants such as Arabidopsis thaliana have allowed researchers to understand pathways that maintain chromatin modifications as well as the mapping of modifications such as DNA methylation on a genome-wide scale. Small RNAs have also been implicated in playing a role in the distribution of chromatin modifications, and RNA may also play a role in the complex epigenetic interactions that occur between homologous sequences (Moazed et al, 2009). In the future, by understanding epigenetic control, researchers can uncover the research necessary to improve plant growth, yields, and transformation efficiency especially in the face of climate change and other environmental factors.</p> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/chromatin-and-transcription-factors.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <h3 style="font-weight: 100; margin-top: 0;">Chromatin</h3> <p>Chromatin consists of nucleosomes formed by a complex of histone proteins and DNA, which allows the packaging of DNA into the nucleus. The less condensed euchromatin represents transcriptionally active regions, while heterochromatin is usually inactive (Vaillant and Paszkowski, 2007). Chromatin state is known to be influenced by both DNA methylation and histone modifications which in turn impact gene expression and the structure of chromosomes. In a recent study, the role of chromatin modifications during plant reproduction elucidated 3-dimensional chromosome reorganization mediated by histones and DNA methylation (Dukowic-Schulze et al. 2017). In addition, gibberellins have been shown in increasing the level of histone acetylation, which affects regions of chromatin involved in maize seed germination (Zheng et al. 2017). Another study reports a novel function of a tomato histone deacetylase gene in the regulation of fruit ripening (Guo et al. 2017).</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/cherry-tomato-common-grape-vine-ripening-fruit-vegetable-cherry-tomatoes.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <p>In addition, multigene families encode transcription factors, with members found throughout the genome or clustered on the same chromosome. Numerous DNA binding proteins that interact with plant promoters have been identified -- some are similar to well-characterized transcription factors in animals or yeast, while others are unique to plants. For example, diverse members of the subfamily X of the plant-specific ethylene response factor (ERF) transcription factors coordinate stress signaling with wound repair activation. Tissue repair is also enhanced through a protein complex of ERF and GRAS TFs (Heyman et. al,.2018). A compilation of known plant transcription factors can be found in the plant transcription factor database at http://plntfdb.bio.uni-potsdam.de/v3.0/.</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/rna-strand.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <h3 style="font-weight: 100; margin-top: 0;">RNA</h3> <p>Recent research shows that a number of classes of small RNAs are key epigenetic regulators. In many cases, small RNAs have been implicated in DNA methylation and chromatin modification (Meyer, 2015). In addition, the role of small RNAs has been implicated in plant stress tolerance (Kumar et al., 2017). López-Galiano et al also provided insight into a coordinated function of a miRNA gene and histone modifications in regulating the expression of a WRKY transcription factor in response to stress.</p> <p>RNA interference (RNAi) is another epigenetic mechanism that leads to small RNA generation, which mediates gene silencing at the post-transcriptional level. RNAi technology has immense potential for plant disease resistance.</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/dna-methylation.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <h3 style="font-weight: 100; margin-top: 0;">DNA methylation</h3> <p>Plants, unlike animals, have three sites that can be methylated G, CHG (H can be A, C, T), and CHH (Law and Jacobsen, 2010). DNA methylation has attracted particular interest. In Arabidopsis, one-third of methylated genes occur in transcribed regions, and 5% of genes are methylated in promoter regions, suggesting that many of these are epigenetically regulated. (Zhang et al., 2006).</p> <p>There are thousands of differentially methylated regions (DMRs) that influence phenotype by influencing gene expression. The analysis of epigenetic recombinant inbred line (epiRIL) plants from Arabidopsis points to the evidence of the influence of DMRs. An epiRIL results from crossing two genetically identical plants with differing DNA methylation levels (with one parent as a homozygous mutant for an essential DNA methylation maintenance gene). The offspring of these plants have similar genomes that vary only in methylation levels. Many traits have been studied using epiRILs -- flowering time, plant height, and response to abiotic stress, some of which have now been mapped to DMRs (Zhang et al. 2018)</p> <p>Regulation by DNA methylation has been shown to be important in many aspects of plant development and response such as vernalization, hybrid vigor, and self-incompatibility (Itabashi et al. 2017). For example, vernalization treatments have shown reduced DNA methylation and subsequent initiation of flowering (Burn et al., 1993). Stress can also influence DNA methylation in plants as a response to environmental stimuli. (Steward et al., 2002; Song et al., 2012). A high degree of DNA methylation has also suggested the role in the improvement of plant fitness under different environmental conditions (Saéz-Laguna et al., 2014). In addition, methylation can affect normal fruit and hypomethylation predicts homeotic transformation and loss of fruit yield (Ong-Abdullah et al., 2015)</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/plant-development.jpg" class="left" style="padding-right: 15px;" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <p>DNA demethylation has also been implied in various aspects of plant development including pollen tube formation, embryogenesis, fruit ripening, stomatal development, and nodule formation ( Li et al. 2017). Demethylation of rice genomic DNA caused an altered pattern of gene expression, inducing dwarf plants (Sano et al., 1990).</p> <p>Epigenetic modifications contribute to the stability and survival of the plants and their ability to adapt in different environmental conditions.</p> </div> </div> <h3>Diagenode products for your epigenomics research in plants</h3> <div class="row extra-spaced"> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #099f92; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/chromatin-function">Chromatin analysis</a></h3> <center><a href="https://www.diagenode.com/en/categories/chromatin-function"><img src="https://www.diagenode.com/img/cancer/chromatin-icon.png" /></a></center> <p class="text-left">Understand the role of chromatin in plant function and development</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/chromatin-function">Learn about our chromatin analysis products</a></li> <li><a href="https://www.diagenode.com/en/p/universal-plant-chip-seq-kit-x24-24-rxns"> Learn about the Universal Plant ChIP Kit</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #30415c; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/dna-methylation" style="color: #30415c;">DNA methylation</a></h3> <center><a href="https://www.diagenode.com/en/categories/dna-methylation"><img src="https://www.diagenode.com/img/cancer/dna-icon.png" /></a></center> <p class="text-left">DNA methylation and demethylation and the effects on plant response and function</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/dna-methylation">Discover DNA methylation analysis solutions at any resolution</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #474546; height: 275px;"> <h3 class="text-center"><span class="darkgrey">Non-coding RNAs</span></h3> <center><img src="https://www.diagenode.com/img/cancer/non-coding-icon.png" /></center> <p class="text-left">Discover noncoding RNAs in the regulation of gene expression in plants</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/Library-preparation-for-RNA-seq">Library prep for RNA-seq studies for ncRNAs</a></li> </ul> </div> </div> <h3>References</h3> <p><small> Burn, J. et al (1993).

Immune cells depend on the expression of specific cell-surface molecules to recognize and eliminate cancer cells. However, tumor cells can take over various epigenetic mechanisms and subsequently use epigenetic silencing to shut off this crucial expression, thereby escaping the recognition from immune cells. Epigenetic modifiers can also reactivate many silenced genes such as immune checkpoints regulators that turn on immune response.</span></p> <p>As a result, in recent years, epigenetic drugs have been a topic of keen interest for clinical researchers. These drugs include promising immunomodulatory agents that may restore expression of cell-surface molecules that allow cancer cells to once again be detectable as well as other targeting agents that trigger antitumor immune responses. Epigenetic therapies, either alone or in combination with current immunotherapies, may lead to new approaches for cancer treatment.</p> <p>The idea of combination therapy for treating cancers has become especially critical. Many patients either do not respond, become resistant, or suffer toxicities from current immunotherapy treatments alone. The combination of epigenetic therapy with common immunotherapies such as interleukin-2 therapy, adoptive T-cell transfer, and immune checkpoint inhibitors, among others are just a few of the strategies being tested with various cancer types in clinical trials. Researchers have demonstrated that combining epigenetic drugs, such as the DNA methyltransferase inhibitors 5-aza-2′-deoxycytidine and guadecitabine, with immunomodulating antibodies that target CTLA-4 or the PD-1/PDL-1 immune checkpoint improves therapeutic efficacy.</p> <p>Additionally, epigenomic signatures in immune and cancer cells may be predictors of success of immunotherapy for patients. Candidate epigenetic biomarkers may improve patient classification and personalized medicine to maximize treatment success and minimize negative effects. Potential biomarkers have been identified in the literature as predictors of the cancer response to immunotherapy such as PD-L1 expression, tumor-associated antigens (TAAs), HLA expression , tumor mutational burden and neoantigen identification , mismatch repair deficiency to name a few. The epigenetic control of these events has been validated. Epigenetic biomarkers may offer additional advantages, such as revealing information about the life habits and conditions of patients, details about the origin of the tumors, predictive indicators, and therapy-monitoring indicators.</p> </div> <h3>Diagenode products for your epigenomics research in Cancer</h3> <div class="row"> <div class="small-12 medium-4 large-4 columns text-left"> <div

Epigenetic changes such as histone modifications, </span><b>DNA methylation</b><span style="font-weight: 400;">, chromatin remodeling, and non-coding RNAs function as important regulators that alter host expression patterns. These changes have important implications to the virus itself since it relies on the host cell to replicate its genetic material and continue to proliferate.

The enzyme neutral sphingomyelinase 2 (nSMase2) is involved in the biogenesis of ceramide and extracellular vesicles (EVs), both of which are dysregulated in PLH, CI, and MDD. Here we evaluated EcoHIV-infected mice for behavioral abnormalities relevant to depression and cognition deficits, and assessed the behavioral and biochemical effects of nSMase2 inhibition. Mice were infected with EcoHIV and daily treatment with either vehicle or the nSMase2 inhibitor (R)-(1-(3-(3,4-dimethoxyphenyl)-2,6-dimethylimidazo[1,2-b]pyridazin-8-yl)pyrrolidin-3-yl)-carbamate (PDDC) began 3 weeks post-infection. After 2 weeks of treatment, mice were subjected to behavior tests. EcoHIV-infected mice exhibited behavioral abnormalities relevant to MDD and CI that were reversed by PDDC treatment. EcoHIV infection significantly increased cortical brain nSMase2 activity, resulting in trend changes in sphingomyelin and ceramide levels that were normalized by PDDC treatment. EcoHIV-infected mice also exhibited increased levels of brain-derived EVs and altered microRNA cargo, including miR-183-5p, miR-200c-3p, miR-200b-3p, and miR-429-3p, known to be associated with MDD and CI; all were normalized by PDDC. In conclusion, inhibition of nSMase2 represents a possible new therapeutic strategy for the treatment of HIV-associated CI and MDD.</p>', 'date' => '2022-07-01', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/35462006', 'doi' => '10.1016/j.nbd.2022.105734', 'modified' => '2022-08-04 15:59:55', 'created' => '2022-08-04 14:55:36', 'ProductsPublication' => array( 'id' => '5972', 'product_id' => '3045', 'publication_id' => '4375' ) ) $externalLink = ' <a href="https://www.ncbi.nlm.nih.gov/pubmed/35462006" target="_blank"><i class="fa fa-external-link"></i></a>'include - APP/View/Products/view.ctp, line 755 View::_evaluate() - CORE/Cake/View/View.php, line 971 View::_render() - CORE/Cake/View/View.php, line 933 View::render() - CORE/Cake/View/View.php, line 473 Controller::render() - CORE/Cake/Controller/Controller.php, line 963 ProductsController::slug() - APP/Controller/ProductsController.php, line 1052 ReflectionMethod::invokeArgs() - [internal], line ??

We recommend using MGcount*, a counting tool developed at Diagenode with a suitable annotations file that include the small RNA transcripts that are object of study. MGcount, built on top of featureCounts, employs a flexible quantification approach to deal with datasets containing multiple RNA biotypes such as D-plex libraries. Non-coding RNAs varying in length, biogenesis, and function, may overlap in a genomic region, and are sometimes present in the genome with a high copy number. Consequently, reads may align equally well to more than one position in the reference genome or/and align to a position where more than one annotated transcript is located. MGcount employs two strategies to quantify these reads. Firstly, it assigns reads in rounds prioritizing small-RNAs over long-RNAs ensuring the unbiased read attribution to intergenic and intragenic small RNAs while preventing host-genes transcription over-estimation. Secondly, MGcount collapses loci where reads consistently multi-map into communities of loci with a graph-based approach. The resultant communities are groups of biologically related loci with nearly identical sequence. Subsequently, quantification of reads is performed at the loci-community level, reducing multi-alignments ambiguity at individual locus. Ultimately, this strategy maximizes the transcriptome information analysed and improves the interrogation of non-coding RNAs. MGcount software repository provides annotation files for A. thaliana, H. sapiens, M. musculus and C. elegans. The required input files for MGcount are a .txt file listing the paths to the alignment input files (.bam format) and the annotations file (.gtf format). The output directory path has to be provided as an input as well.</p> <p><strong>Example command:</strong></p> <p style="background-color: #f0f0f0;">MGcount -T 2 --gtf Homo_sapiens.GRCh38.gtf --outdir outputs --bam_infiles input_bamfilenames.txt</p> <p>MGcount provides the choice to enable/disable the quantification of all RNA biotypes included in the annotation file in the form of "communities" as optional parameters for small-RNA (--ml_flag_small) and long-RNA (--ml_flag_long). Both are enabled by default. The main output of MGcount is the count_matrix.csv file containing an expression matrix that can be imported to R or any other software for downstream analyses.<br />A full user guide for MGCount is available here: <a href="https://filedn.com/lTnUWxFTA93JTyX3Hvbdn2h/mgcount/UserGuide.html">https://filedn.com/lTnUWxFTA93JTyX3Hvbdn2h/mgcount/UserGuide.html</a>.</p> <p>Other standard counting tools such as featureCounts or HTSeq-counts can also be used alternatively. Given the high complexity of D-Plex libraries, we recommend having a clear understanding of the scientific question and the goal of the project before proceeding to the choice of the counting method as this will strongly impact downstream analyses. Diagenode provides bioinformatics support as a service (please, contact us if you need help with data analysis).</p> <p>Notice that D-Plex produces forward-stranded data. Stranded libraries have the benefit that reads map to the genome strand where they were originated from. Therefore, when estimating transcript expression, reads aligned to the forward strand should be assigned only to transcript features in the forward strand whereas reads aligned to the reverse strand should be assigned only to transcript features in the reverse strand.

ワークフローは、4つのヌクレオチド(それぞれ異なる蛍光色素で標識された)の組み込み、4色イメージング、色素や末端基の切断、取り込み、イメージングなどを繰り返します。フローセルは大規模な並列配列決定を受ける。 この方法により、単一蛍光標識されたヌクレオチドの制御添加によるモノヌクレオチドのエラーを回避する可能性があります。 読み取りの長さは、通常約100〜150 bpです。</p> <h3><a

However, molecular events in end-organ diseases such as central nervous system (CNS) disease are not yet fully understood, and routine eradication of latent reservoirs is not yet in reach. Extracellular vesicle (EV) RNAs have emerged as important participants in HIV disease pathogenesis. Brain tissue-derived EVs (bdEVs) act locally in the source tissue and may indicate molecular mechanisms in HIV CNS pathology. Using brain tissue and bdEVs from the simian immunodeficiency virus (SIV) model of HIV disease, we profiled messenger RNAs (mRNAs), microRNAs (miRNAs), and circular RNAs (circRNAs), seeking to identify possible networks of RNA interaction in SIV infection and neuroinflammation. Methods: Postmortem occipital cortex tissues were obtained from pigtailed macaques either not infected or dual-inoculated with SIV swarm B670 and clone SIV/17E-Fr. SIV-inoculated groups included samples collected at different time points during acute infection or chronic infection without or with CNS pathology (CP- or CP+). bdEVs were separated and characterized in accordance with international consensus standards. RNAs from bdEVs and source tissue were used for sequencing and qPCR to detect mRNA, miRNA, and circRNA levels. Results: Multiple dysregulated bdEV RNAs, including mRNAs, miRNAs, and circRNAs, were identified in acute and CP+. Most dysregulated mRNAs in bdEVs reflected dysregulation in their source tissues. These mRNAs are disproportionately involved in inflammation and immune responses, especially interferon pathways. For miRNAs, qPCR assays confirmed differential abundance of miR-19a-3p, let-7a-5p, and miR-29a-3p (acute phase), and miR-146a-5p and miR-449a-5p (CP+) in bdEVs. In addition, target prediction suggested that several circRNAs that were differentially abundant in source tissue might be responsible for specific differences in small RNA levels in bdEVs during SIV infection. RNA profiling of bdEVs and source tissues reveals potential regulatory networks in SIV infection and SIV- related CNS pathology.</p>', 'date' => '2023-04-01', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/37034720', 'doi' => '10.1101/2023.04.01.535193', 'modified' => '2023-06-12 09:04:45', 'created' => '2023-05-05 12:34:24', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 1 => array( 'id' => '4375', 'name' => 'Neutral sphingomyelinase 2 inhibition attenuates extracellular vesiclerelease and improves neurobehavioral deficits in murine HIV.', 'authors' => 'Zhu X. et al.', 'description' => '<p>People living with HIV (PLH) have significantly higher rates of cognitive impairment (CI) and major depressive disorder (MDD) versus the general population.

Here we evaluated EcoHIV-infected mice for behavioral abnormalities relevant to depression and cognition deficits, and assessed the behavioral and biochemical effects of nSMase2 inhibition.

EcoHIV infection significantly increased cortical brain nSMase2 activity, resulting in trend changes in sphingomyelin and ceramide levels that were normalized by PDDC treatment. EcoHIV-infected mice also exhibited increased levels of brain-derived EVs and altered microRNA cargo, including miR-183-5p, miR-200c-3p, miR-200b-3p, and miR-429-3p, known to be associated with MDD and CI; all were normalized by PDDC.

However, disruption of epigenetic mechanisms may alter gene function, potentially leading to cellular transformations that lead to tumorigenesis. Cancer is a multistep process from a succession of processes that alter the growth of normal cells. In cancer, epigenetic reprogramming occurs at multiple levels including nuclear organization and nucleosome positioning, DNA methylation, modification of histones, alteration of epigenetic regulators such as transcription factor binding, and non-coding RNA, such as microRNA.</p> <p>Epigenetic modifications are reversible and potential treatments could be geared to alter irregular transcription factor binding, DNA methylation or histone acetylation. Accurate study with a versatile number of tools is essential for the study of epigenetics including sound sample preparation and analysis methodologies for DNA methylation such as with immunoprecipitation or bisulfite sequencing, chromatin analysis with chromatin immunoprecipitation (ChIP) combined with qPCR or sequencing, and RNA modification study. As researchers elucidate the mechanisms and specific modifications associated with cancer, it may be possible to target abnormal modifications in cells with minimal damage to normal cells, making the prospect of epigenetic therapy increasingly promising.</p> <h3>Diagenode products for your epigenomics research in Cancer</h3> <div class="row"> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #099f92; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/chromatin-function">Chromatin analysis</a></h3> <center><a href="https://www.diagenode.com/en/categories/chromatin-function"><img src="https://www.diagenode.com/img/cancer/chromatin-icon.png" /></a></center> <p class="text-left">Understand the role of chromatin in cancer regulation</p> </div> <ul> <li>New to ChIP? <a href="https://www.diagenode.com/en/pages/portal/chip">Learn more</a></li> <li><a href="https://www.diagenode.com/en/categories/chromatin-shearing">Chromatin shearing optimization</a></li> <li><a href="https://www.diagenode.com/en/categories/chromatin-immunoprecipitation">Chromatin Immunoprecipitation</a></li> <li>Validated <a href="https://www.diagenode.com/en/categories/antibodies">Antibodies</a></li> <li><a href="https://www.diagenode.com/en/categories/library-preparation">Library preparation</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #30415c; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/dna-methylation" style="color: #30415c;">DNA methylation</a></h3> <center><a href="https://www.diagenode.com/en/categories/dna-methylation"><img src="https://www.diagenode.com/img/cancer/dna-icon.png" /></a></center> <p class="text-left">Analyze DNA methylation and the effects on oncogenesis and tumor suppression</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/bisulfite-conversion">Bisulfite sequencing</a></li> <li><a href="https://www.diagenode.com/en/categories/methylated-dna-immunoprecipitation">Methylated DNA immunoprecipitation</a></li> <li><a href="https://www.diagenode.com/en/categories/dna-methylation-profiling-services">DNA methylation services</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #474546; height: 275px;"> <h3 class="text-center"><span class="darkgrey">Non-coding RNAs</span></h3> <center><img src="https://www.diagenode.com/img/cancer/non-coding-icon.png" /></center> <p class="text-left">Discover noncoding RNAs in cancer</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/Library-preparation-for-RNA-seq">RNA-seq using D-Plex</a> </li> <li><a href="https://www.diagenode.com/en/categories/rna-seq-category">RNA-seq services</a></li> </ul> </div> </div> <div id="ConnectiveDocSignExtentionInstalled" data-extension-version="1.0.4"></div> <div id="ConnectiveDocSignExtentionInstalled" data-extension-version="1.0.4"></div>', 'online' => true, 'in_menu' => true, 'slug' => 'cancer', 'cookies_tag_id' => null, 'meta_title' => 'cancer', 'meta_description' => 'cancer', 'meta_keywords' => 'cancer', 'modified' => '2022-11-24 13:21:38', 'created' => '2018-08-03 15:56:34', 'ProductsArea' => array( [maximum depth reached] ) ), (int) 2 => array( 'id' => '3', 'parent_id' => null, 'name' => 'Neuroscience', 'description' => '<div class="extra-spaced"> <p><img src="https://www.diagenode.com/img/areas/neuroscience.jpg" /></p> </div> <h2>Epigenetics in Neuroscience</h2> <p>Neuroscience and epigenetics are at an exciting crossroads. Current research has shown that epigenetic mechanisms play a critical role in both behavior and the development and function of the nervous system. Histone modifications, changes in DNA methylation, and non-coding RNAs regulate various stages of neurogenesis and brain development while aberrant epigenetic regulation has been implicated in a number of neurological and brain disorders (Yao et, al. Nature Reviews Neuroscience, 2016).</p> <p>Neuroscientists seek to uncover how epigenetic marks and transcriptional changes regulate gene expression to influence changes in areas such as behavior and the development of neural pathways and brain structures. Understanding how epigenetics affects nervous system function requires an integrative approach incorporating multiple levels of analysis. For example, research has uncovered the role of transcription factors, non-coding RNAs, and other molecules that mediate learning and memory. In addition, chromatin modifications and non-coding RNAs have been shown to influence epigenetic mechanisms in neurogenesis.</p> <p>Understanding the molecular components and environmental conditions that affect epigenetic change will eventually provide the basis to develop therapies to treat neurological and psychiatric conditions. As neuroscientists learn how changes in chromatin architecture affect transcriptional regulation and gene expression, the link between the epigenome and the various areas in neuroscience will become clearer.</p> <h3><span class="diacol">Neuroscience and epigenetics intersect in a number of areas: </span></h3> <ul class="accordion" data-accordion=""> <li class="accordion-navigation"><a href="#memory"> <i class="fa fa-square-o"></i> Epigenetics in memory, memory disorders, and learning</a> <div id="memory" class="content"> <blockquote><br /> <p><strong>Epigenetic mechanisms underlying learning and the inheritance of learned behaviors</strong></p> <p>In this review, researchers outline epigenetic mechanisms by which gene expression is regulated in animals and humans.

Environmental factors such as dietary intake, drugs, stress, or exposure to toxins, can cause epigenetic changes by possibly altering how transcription factors bind to DNA or changing the structure of the histones that DNA wraps around. These structural changes can affect gene activity or gene expression. A number of environmental factors have been investigated for their effect on epigenetic changes including phthalates, toxic metals, smoking, air pollution, jet fuel, environmental stress, and a high fat diet. Effects on epigenetic mechanisms, DNA methylation patterns, histone modifications, miRNA expression have been documented as a result. The table below (Marczylo et al, 2016 and Society of Toxicology, 2018) summarizes a few of the studies that have been done for putative environmentally-induced epigenetic toxicity in humans or rat/mouse.</p> <p class="extra-spaced">In the future, incorporating epigenetic evaluation into toxicity tests can increase the safety of both food and environmental substances.</p> <table class="extra-spaced"> <tbody> <tr> <th style="text-align: center;">Toxin/exposure</th> <th style="text-align: center;">Species/stage of exposure/effect</th> <th style="text-align: center;">Phenotype</th> <th style="text-align: center;">Epigenetic change</th> <th style="text-align: center;">Reference(s)</th> </tr> <tr> <td>Air pollution</td> <td style="text-align: center;">Human/childhood/childhood</td> <td style="text-align: center;">Asthma</td> <td style="text-align: center;">Epigenetic mechanisms</td> <td style="text-align: left;">Somineni et al.

Plants depend on changes in gene expression to respond to environmental stimuli, in which the full repertoire of histone modifications, DNA methylation, and small ncRNAs play an important role in epigenetic regulation.</p> <p>Studying the epigenetics of model plants such as Arabidopsis thaliana have allowed researchers to understand pathways that maintain chromatin modifications as well as the mapping of modifications such as DNA methylation on a genome-wide scale. Small RNAs have also been implicated in playing a role in the distribution of chromatin modifications, and RNA may also play a role in the complex epigenetic interactions that occur between homologous sequences (Moazed et al, 2009). In the future, by understanding epigenetic control, researchers can uncover the research necessary to improve plant growth, yields, and transformation efficiency especially in the face of climate change and other environmental factors.</p> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/chromatin-and-transcription-factors.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <h3 style="font-weight: 100; margin-top: 0;">Chromatin</h3> <p>Chromatin consists of nucleosomes formed by a complex of histone proteins and DNA, which allows the packaging of DNA into the nucleus. The less condensed euchromatin represents transcriptionally active regions, while heterochromatin is usually inactive (Vaillant and Paszkowski, 2007). Chromatin state is known to be influenced by both DNA methylation and histone modifications which in turn impact gene expression and the structure of chromosomes. In a recent study, the role of chromatin modifications during plant reproduction elucidated 3-dimensional chromosome reorganization mediated by histones and DNA methylation (Dukowic-Schulze et al. 2017). In addition, gibberellins have been shown in increasing the level of histone acetylation, which affects regions of chromatin involved in maize seed germination (Zheng et al. 2017). Another study reports a novel function of a tomato histone deacetylase gene in the regulation of fruit ripening (Guo et al. 2017).</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/cherry-tomato-common-grape-vine-ripening-fruit-vegetable-cherry-tomatoes.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <p>In addition, multigene families encode transcription factors, with members found throughout the genome or clustered on the same chromosome. Numerous DNA binding proteins that interact with plant promoters have been identified -- some are similar to well-characterized transcription factors in animals or yeast, while others are unique to plants. For example, diverse members of the subfamily X of the plant-specific ethylene response factor (ERF) transcription factors coordinate stress signaling with wound repair activation. Tissue repair is also enhanced through a protein complex of ERF and GRAS TFs (Heyman et. al,.2018). A compilation of known plant transcription factors can be found in the plant transcription factor database at http://plntfdb.bio.uni-potsdam.de/v3.0/.</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/rna-strand.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <h3 style="font-weight: 100; margin-top: 0;">RNA</h3> <p>Recent research shows that a number of classes of small RNAs are key epigenetic regulators. In many cases, small RNAs have been implicated in DNA methylation and chromatin modification (Meyer, 2015). In addition, the role of small RNAs has been implicated in plant stress tolerance (Kumar et al., 2017). López-Galiano et al also provided insight into a coordinated function of a miRNA gene and histone modifications in regulating the expression of a WRKY transcription factor in response to stress.</p> <p>RNA interference (RNAi) is another epigenetic mechanism that leads to small RNA generation, which mediates gene silencing at the post-transcriptional level. RNAi technology has immense potential for plant disease resistance.</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/dna-methylation.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <h3 style="font-weight: 100; margin-top: 0;">DNA methylation</h3> <p>Plants, unlike animals, have three sites that can be methylated G, CHG (H can be A, C, T), and CHH (Law and Jacobsen, 2010). DNA methylation has attracted particular interest. In Arabidopsis, one-third of methylated genes occur in transcribed regions, and 5% of genes are methylated in promoter regions, suggesting that many of these are epigenetically regulated. (Zhang et al., 2006).</p> <p>There are thousands of differentially methylated regions (DMRs) that influence phenotype by influencing gene expression. The analysis of epigenetic recombinant inbred line (epiRIL) plants from Arabidopsis points to the evidence of the influence of DMRs. An epiRIL results from crossing two genetically identical plants with differing DNA methylation levels (with one parent as a homozygous mutant for an essential DNA methylation maintenance gene). The offspring of these plants have similar genomes that vary only in methylation levels. Many traits have been studied using epiRILs -- flowering time, plant height, and response to abiotic stress, some of which have now been mapped to DMRs (Zhang et al. 2018)</p> <p>Regulation by DNA methylation has been shown to be important in many aspects of plant development and response such as vernalization, hybrid vigor, and self-incompatibility (Itabashi et al. 2017). For example, vernalization treatments have shown reduced DNA methylation and subsequent initiation of flowering (Burn et al., 1993). Stress can also influence DNA methylation in plants as a response to environmental stimuli. (Steward et al., 2002; Song et al., 2012). A high degree of DNA methylation has also suggested the role in the improvement of plant fitness under different environmental conditions (Saéz-Laguna et al., 2014). In addition, methylation can affect normal fruit and hypomethylation predicts homeotic transformation and loss of fruit yield (Ong-Abdullah et al., 2015)</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/plant-development.jpg" class="left" style="padding-right: 15px;" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <p>DNA demethylation has also been implied in various aspects of plant development including pollen tube formation, embryogenesis, fruit ripening, stomatal development, and nodule formation ( Li et al. 2017). Demethylation of rice genomic DNA caused an altered pattern of gene expression, inducing dwarf plants (Sano et al., 1990).</p> <p>Epigenetic modifications contribute to the stability and survival of the plants and their ability to adapt in different environmental conditions.</p> </div> </div> <h3>Diagenode products for your epigenomics research in plants</h3> <div class="row extra-spaced"> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #099f92; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/chromatin-function">Chromatin analysis</a></h3> <center><a href="https://www.diagenode.com/en/categories/chromatin-function"><img src="https://www.diagenode.com/img/cancer/chromatin-icon.png" /></a></center> <p class="text-left">Understand the role of chromatin in plant function and development</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/chromatin-function">Learn about our chromatin analysis products</a></li> <li><a href="https://www.diagenode.com/en/p/universal-plant-chip-seq-kit-x24-24-rxns"> Learn about the Universal Plant ChIP Kit</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #30415c; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/dna-methylation" style="color: #30415c;">DNA methylation</a></h3> <center><a href="https://www.diagenode.com/en/categories/dna-methylation"><img src="https://www.diagenode.com/img/cancer/dna-icon.png" /></a></center> <p class="text-left">DNA methylation and demethylation and the effects on plant response and function</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/dna-methylation">Discover DNA methylation analysis solutions at any resolution</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #474546; height: 275px;"> <h3 class="text-center"><span class="darkgrey">Non-coding RNAs</span></h3> <center><img src="https://www.diagenode.com/img/cancer/non-coding-icon.png" /></center> <p class="text-left">Discover noncoding RNAs in the regulation of gene expression in plants</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/Library-preparation-for-RNA-seq">Library prep for RNA-seq studies for ncRNAs</a></li> </ul> </div> </div> <h3>References</h3> <p><small> Burn, J. et al (1993).

Immune cells depend on the expression of specific cell-surface molecules to recognize and eliminate cancer cells. However, tumor cells can take over various epigenetic mechanisms and subsequently use epigenetic silencing to shut off this crucial expression, thereby escaping the recognition from immune cells. Epigenetic modifiers can also reactivate many silenced genes such as immune checkpoints regulators that turn on immune response.</span></p> <p>As a result, in recent years, epigenetic drugs have been a topic of keen interest for clinical researchers. These drugs include promising immunomodulatory agents that may restore expression of cell-surface molecules that allow cancer cells to once again be detectable as well as other targeting agents that trigger antitumor immune responses. Epigenetic therapies, either alone or in combination with current immunotherapies, may lead to new approaches for cancer treatment.</p> <p>The idea of combination therapy for treating cancers has become especially critical. Many patients either do not respond, become resistant, or suffer toxicities from current immunotherapy treatments alone. The combination of epigenetic therapy with common immunotherapies such as interleukin-2 therapy, adoptive T-cell transfer, and immune checkpoint inhibitors, among others are just a few of the strategies being tested with various cancer types in clinical trials. Researchers have demonstrated that combining epigenetic drugs, such as the DNA methyltransferase inhibitors 5-aza-2′-deoxycytidine and guadecitabine, with immunomodulating antibodies that target CTLA-4 or the PD-1/PDL-1 immune checkpoint improves therapeutic efficacy.</p> <p>Additionally, epigenomic signatures in immune and cancer cells may be predictors of success of immunotherapy for patients. Candidate epigenetic biomarkers may improve patient classification and personalized medicine to maximize treatment success and minimize negative effects. Potential biomarkers have been identified in the literature as predictors of the cancer response to immunotherapy such as PD-L1 expression, tumor-associated antigens (TAAs), HLA expression , tumor mutational burden and neoantigen identification , mismatch repair deficiency to name a few. The epigenetic control of these events has been validated. Epigenetic biomarkers may offer additional advantages, such as revealing information about the life habits and conditions of patients, details about the origin of the tumors, predictive indicators, and therapy-monitoring indicators.</p> </div> <h3>Diagenode products for your epigenomics research in Cancer</h3> <div class="row"> <div class="small-12 medium-4 large-4 columns text-left"> <div

Epigenetic changes such as histone modifications, </span><b>DNA methylation</b><span style="font-weight: 400;">, chromatin remodeling, and non-coding RNAs function as important regulators that alter host expression patterns. These changes have important implications to the virus itself since it relies on the host cell to replicate its genetic material and continue to proliferate.

The enzyme neutral sphingomyelinase 2 (nSMase2) is involved in the biogenesis of ceramide and extracellular vesicles (EVs), both of which are dysregulated in PLH, CI, and MDD. Here we evaluated EcoHIV-infected mice for behavioral abnormalities relevant to depression and cognition deficits, and assessed the behavioral and biochemical effects of nSMase2 inhibition. Mice were infected with EcoHIV and daily treatment with either vehicle or the nSMase2 inhibitor (R)-(1-(3-(3,4-dimethoxyphenyl)-2,6-dimethylimidazo[1,2-b]pyridazin-8-yl)pyrrolidin-3-yl)-carbamate (PDDC) began 3 weeks post-infection. After 2 weeks of treatment, mice were subjected to behavior tests. EcoHIV-infected mice exhibited behavioral abnormalities relevant to MDD and CI that were reversed by PDDC treatment. EcoHIV infection significantly increased cortical brain nSMase2 activity, resulting in trend changes in sphingomyelin and ceramide levels that were normalized by PDDC treatment. EcoHIV-infected mice also exhibited increased levels of brain-derived EVs and altered microRNA cargo, including miR-183-5p, miR-200c-3p, miR-200b-3p, and miR-429-3p, known to be associated with MDD and CI; all were normalized by PDDC. In conclusion, inhibition of nSMase2 represents a possible new therapeutic strategy for the treatment of HIV-associated CI and MDD.</p>', 'date' => '2022-07-01', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/35462006', 'doi' => '10.1016/j.nbd.2022.105734', 'modified' => '2022-08-04 15:59:55', 'created' => '2022-08-04 14:55:36', 'ProductsPublication' => array( 'id' => '5972', 'product_id' => '3045', 'publication_id' => '4375' ) ) $externalLink = ' <a href="https://www.ncbi.nlm.nih.gov/pubmed/35462006" target="_blank"><i class="fa fa-external-link"></i></a>'include - APP/View/Products/view.ctp, line 755 View::_evaluate() - CORE/Cake/View/View.php, line 971 View::_render() - CORE/Cake/View/View.php, line 933 View::render() - CORE/Cake/View/View.php, line 473 Controller::render() - CORE/Cake/Controller/Controller.php, line 963 ProductsController::slug() - APP/Controller/ProductsController.php, line 1052 ReflectionMethod::invokeArgs() - [internal], line ??

We recommend using MGcount*, a counting tool developed at Diagenode with a suitable annotations file that include the small RNA transcripts that are object of study. MGcount, built on top of featureCounts, employs a flexible quantification approach to deal with datasets containing multiple RNA biotypes such as D-plex libraries. Non-coding RNAs varying in length, biogenesis, and function, may overlap in a genomic region, and are sometimes present in the genome with a high copy number. Consequently, reads may align equally well to more than one position in the reference genome or/and align to a position where more than one annotated transcript is located. MGcount employs two strategies to quantify these reads. Firstly, it assigns reads in rounds prioritizing small-RNAs over long-RNAs ensuring the unbiased read attribution to intergenic and intragenic small RNAs while preventing host-genes transcription over-estimation. Secondly, MGcount collapses loci where reads consistently multi-map into communities of loci with a graph-based approach. The resultant communities are groups of biologically related loci with nearly identical sequence. Subsequently, quantification of reads is performed at the loci-community level, reducing multi-alignments ambiguity at individual locus. Ultimately, this strategy maximizes the transcriptome information analysed and improves the interrogation of non-coding RNAs. MGcount software repository provides annotation files for A. thaliana, H. sapiens, M. musculus and C. elegans. The required input files for MGcount are a .txt file listing the paths to the alignment input files (.bam format) and the annotations file (.gtf format). The output directory path has to be provided as an input as well.</p> <p><strong>Example command:</strong></p> <p style="background-color: #f0f0f0;">MGcount -T 2 --gtf Homo_sapiens.GRCh38.gtf --outdir outputs --bam_infiles input_bamfilenames.txt</p> <p>MGcount provides the choice to enable/disable the quantification of all RNA biotypes included in the annotation file in the form of "communities" as optional parameters for small-RNA (--ml_flag_small) and long-RNA (--ml_flag_long). Both are enabled by default. The main output of MGcount is the count_matrix.csv file containing an expression matrix that can be imported to R or any other software for downstream analyses.<br />A full user guide for MGCount is available here: <a href="https://filedn.com/lTnUWxFTA93JTyX3Hvbdn2h/mgcount/UserGuide.html">https://filedn.com/lTnUWxFTA93JTyX3Hvbdn2h/mgcount/UserGuide.html</a>.</p> <p>Other standard counting tools such as featureCounts or HTSeq-counts can also be used alternatively. Given the high complexity of D-Plex libraries, we recommend having a clear understanding of the scientific question and the goal of the project before proceeding to the choice of the counting method as this will strongly impact downstream analyses. Diagenode provides bioinformatics support as a service (please, contact us if you need help with data analysis).</p> <p>Notice that D-Plex produces forward-stranded data. Stranded libraries have the benefit that reads map to the genome strand where they were originated from. Therefore, when estimating transcript expression, reads aligned to the forward strand should be assigned only to transcript features in the forward strand whereas reads aligned to the reverse strand should be assigned only to transcript features in the reverse strand.

ワークフローは、4つのヌクレオチド(それぞれ異なる蛍光色素で標識された)の組み込み、4色イメージング、色素や末端基の切断、取り込み、イメージングなどを繰り返します。フローセルは大規模な並列配列決定を受ける。 この方法により、単一蛍光標識されたヌクレオチドの制御添加によるモノヌクレオチドのエラーを回避する可能性があります。 読み取りの長さは、通常約100〜150 bpです。</p> <h3><a

However, molecular events in end-organ diseases such as central nervous system (CNS) disease are not yet fully understood, and routine eradication of latent reservoirs is not yet in reach. Extracellular vesicle (EV) RNAs have emerged as important participants in HIV disease pathogenesis. Brain tissue-derived EVs (bdEVs) act locally in the source tissue and may indicate molecular mechanisms in HIV CNS pathology. Using brain tissue and bdEVs from the simian immunodeficiency virus (SIV) model of HIV disease, we profiled messenger RNAs (mRNAs), microRNAs (miRNAs), and circular RNAs (circRNAs), seeking to identify possible networks of RNA interaction in SIV infection and neuroinflammation. Methods: Postmortem occipital cortex tissues were obtained from pigtailed macaques either not infected or dual-inoculated with SIV swarm B670 and clone SIV/17E-Fr. SIV-inoculated groups included samples collected at different time points during acute infection or chronic infection without or with CNS pathology (CP- or CP+). bdEVs were separated and characterized in accordance with international consensus standards. RNAs from bdEVs and source tissue were used for sequencing and qPCR to detect mRNA, miRNA, and circRNA levels. Results: Multiple dysregulated bdEV RNAs, including mRNAs, miRNAs, and circRNAs, were identified in acute and CP+. Most dysregulated mRNAs in bdEVs reflected dysregulation in their source tissues. These mRNAs are disproportionately involved in inflammation and immune responses, especially interferon pathways. For miRNAs, qPCR assays confirmed differential abundance of miR-19a-3p, let-7a-5p, and miR-29a-3p (acute phase), and miR-146a-5p and miR-449a-5p (CP+) in bdEVs. In addition, target prediction suggested that several circRNAs that were differentially abundant in source tissue might be responsible for specific differences in small RNA levels in bdEVs during SIV infection. RNA profiling of bdEVs and source tissues reveals potential regulatory networks in SIV infection and SIV- related CNS pathology.</p>', 'date' => '2023-04-01', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/37034720', 'doi' => '10.1101/2023.04.01.535193', 'modified' => '2023-06-12 09:04:45', 'created' => '2023-05-05 12:34:24', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 1 => array( 'id' => '4375', 'name' => 'Neutral sphingomyelinase 2 inhibition attenuates extracellular vesiclerelease and improves neurobehavioral deficits in murine HIV.', 'authors' => 'Zhu X. et al.', 'description' => '<p>People living with HIV (PLH) have significantly higher rates of cognitive impairment (CI) and major depressive disorder (MDD) versus the general population.

Here we evaluated EcoHIV-infected mice for behavioral abnormalities relevant to depression and cognition deficits, and assessed the behavioral and biochemical effects of nSMase2 inhibition.

EcoHIV infection significantly increased cortical brain nSMase2 activity, resulting in trend changes in sphingomyelin and ceramide levels that were normalized by PDDC treatment. EcoHIV-infected mice also exhibited increased levels of brain-derived EVs and altered microRNA cargo, including miR-183-5p, miR-200c-3p, miR-200b-3p, and miR-429-3p, known to be associated with MDD and CI; all were normalized by PDDC.

However, disruption of epigenetic mechanisms may alter gene function, potentially leading to cellular transformations that lead to tumorigenesis. Cancer is a multistep process from a succession of processes that alter the growth of normal cells. In cancer, epigenetic reprogramming occurs at multiple levels including nuclear organization and nucleosome positioning, DNA methylation, modification of histones, alteration of epigenetic regulators such as transcription factor binding, and non-coding RNA, such as microRNA.</p> <p>Epigenetic modifications are reversible and potential treatments could be geared to alter irregular transcription factor binding, DNA methylation or histone acetylation. Accurate study with a versatile number of tools is essential for the study of epigenetics including sound sample preparation and analysis methodologies for DNA methylation such as with immunoprecipitation or bisulfite sequencing, chromatin analysis with chromatin immunoprecipitation (ChIP) combined with qPCR or sequencing, and RNA modification study. As researchers elucidate the mechanisms and specific modifications associated with cancer, it may be possible to target abnormal modifications in cells with minimal damage to normal cells, making the prospect of epigenetic therapy increasingly promising.</p> <h3>Diagenode products for your epigenomics research in Cancer</h3> <div class="row"> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #099f92; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/chromatin-function">Chromatin analysis</a></h3> <center><a href="https://www.diagenode.com/en/categories/chromatin-function"><img src="https://www.diagenode.com/img/cancer/chromatin-icon.png" /></a></center> <p class="text-left">Understand the role of chromatin in cancer regulation</p> </div> <ul> <li>New to ChIP? <a href="https://www.diagenode.com/en/pages/portal/chip">Learn more</a></li> <li><a href="https://www.diagenode.com/en/categories/chromatin-shearing">Chromatin shearing optimization</a></li> <li><a href="https://www.diagenode.com/en/categories/chromatin-immunoprecipitation">Chromatin Immunoprecipitation</a></li> <li>Validated <a href="https://www.diagenode.com/en/categories/antibodies">Antibodies</a></li> <li><a href="https://www.diagenode.com/en/categories/library-preparation">Library preparation</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #30415c; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/dna-methylation" style="color: #30415c;">DNA methylation</a></h3> <center><a href="https://www.diagenode.com/en/categories/dna-methylation"><img src="https://www.diagenode.com/img/cancer/dna-icon.png" /></a></center> <p class="text-left">Analyze DNA methylation and the effects on oncogenesis and tumor suppression</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/bisulfite-conversion">Bisulfite sequencing</a></li> <li><a href="https://www.diagenode.com/en/categories/methylated-dna-immunoprecipitation">Methylated DNA immunoprecipitation</a></li> <li><a href="https://www.diagenode.com/en/categories/dna-methylation-profiling-services">DNA methylation services</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #474546; height: 275px;"> <h3 class="text-center"><span class="darkgrey">Non-coding RNAs</span></h3> <center><img src="https://www.diagenode.com/img/cancer/non-coding-icon.png" /></center> <p class="text-left">Discover noncoding RNAs in cancer</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/Library-preparation-for-RNA-seq">RNA-seq using D-Plex</a> </li> <li><a href="https://www.diagenode.com/en/categories/rna-seq-category">RNA-seq services</a></li> </ul> </div> </div> <div id="ConnectiveDocSignExtentionInstalled" data-extension-version="1.0.4"></div> <div id="ConnectiveDocSignExtentionInstalled" data-extension-version="1.0.4"></div>', 'online' => true, 'in_menu' => true, 'slug' => 'cancer', 'cookies_tag_id' => null, 'meta_title' => 'cancer', 'meta_description' => 'cancer', 'meta_keywords' => 'cancer', 'modified' => '2022-11-24 13:21:38', 'created' => '2018-08-03 15:56:34', 'ProductsArea' => array( [maximum depth reached] ) ), (int) 2 => array( 'id' => '3', 'parent_id' => null, 'name' => 'Neuroscience', 'description' => '<div class="extra-spaced"> <p><img src="https://www.diagenode.com/img/areas/neuroscience.jpg" /></p> </div> <h2>Epigenetics in Neuroscience</h2> <p>Neuroscience and epigenetics are at an exciting crossroads. Current research has shown that epigenetic mechanisms play a critical role in both behavior and the development and function of the nervous system. Histone modifications, changes in DNA methylation, and non-coding RNAs regulate various stages of neurogenesis and brain development while aberrant epigenetic regulation has been implicated in a number of neurological and brain disorders (Yao et, al. Nature Reviews Neuroscience, 2016).</p> <p>Neuroscientists seek to uncover how epigenetic marks and transcriptional changes regulate gene expression to influence changes in areas such as behavior and the development of neural pathways and brain structures. Understanding how epigenetics affects nervous system function requires an integrative approach incorporating multiple levels of analysis. For example, research has uncovered the role of transcription factors, non-coding RNAs, and other molecules that mediate learning and memory. In addition, chromatin modifications and non-coding RNAs have been shown to influence epigenetic mechanisms in neurogenesis.</p> <p>Understanding the molecular components and environmental conditions that affect epigenetic change will eventually provide the basis to develop therapies to treat neurological and psychiatric conditions. As neuroscientists learn how changes in chromatin architecture affect transcriptional regulation and gene expression, the link between the epigenome and the various areas in neuroscience will become clearer.</p> <h3><span class="diacol">Neuroscience and epigenetics intersect in a number of areas: </span></h3> <ul class="accordion" data-accordion=""> <li class="accordion-navigation"><a href="#memory"> <i class="fa fa-square-o"></i> Epigenetics in memory, memory disorders, and learning</a> <div id="memory" class="content"> <blockquote><br /> <p><strong>Epigenetic mechanisms underlying learning and the inheritance of learned behaviors</strong></p> <p>In this review, researchers outline epigenetic mechanisms by which gene expression is regulated in animals and humans.

Environmental factors such as dietary intake, drugs, stress, or exposure to toxins, can cause epigenetic changes by possibly altering how transcription factors bind to DNA or changing the structure of the histones that DNA wraps around. These structural changes can affect gene activity or gene expression. A number of environmental factors have been investigated for their effect on epigenetic changes including phthalates, toxic metals, smoking, air pollution, jet fuel, environmental stress, and a high fat diet. Effects on epigenetic mechanisms, DNA methylation patterns, histone modifications, miRNA expression have been documented as a result. The table below (Marczylo et al, 2016 and Society of Toxicology, 2018) summarizes a few of the studies that have been done for putative environmentally-induced epigenetic toxicity in humans or rat/mouse.</p> <p class="extra-spaced">In the future, incorporating epigenetic evaluation into toxicity tests can increase the safety of both food and environmental substances.</p> <table class="extra-spaced"> <tbody> <tr> <th style="text-align: center;">Toxin/exposure</th> <th style="text-align: center;">Species/stage of exposure/effect</th> <th style="text-align: center;">Phenotype</th> <th style="text-align: center;">Epigenetic change</th> <th style="text-align: center;">Reference(s)</th> </tr> <tr> <td>Air pollution</td> <td style="text-align: center;">Human/childhood/childhood</td> <td style="text-align: center;">Asthma</td> <td style="text-align: center;">Epigenetic mechanisms</td> <td style="text-align: left;">Somineni et al.

Plants depend on changes in gene expression to respond to environmental stimuli, in which the full repertoire of histone modifications, DNA methylation, and small ncRNAs play an important role in epigenetic regulation.</p> <p>Studying the epigenetics of model plants such as Arabidopsis thaliana have allowed researchers to understand pathways that maintain chromatin modifications as well as the mapping of modifications such as DNA methylation on a genome-wide scale. Small RNAs have also been implicated in playing a role in the distribution of chromatin modifications, and RNA may also play a role in the complex epigenetic interactions that occur between homologous sequences (Moazed et al, 2009). In the future, by understanding epigenetic control, researchers can uncover the research necessary to improve plant growth, yields, and transformation efficiency especially in the face of climate change and other environmental factors.</p> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/chromatin-and-transcription-factors.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <h3 style="font-weight: 100; margin-top: 0;">Chromatin</h3> <p>Chromatin consists of nucleosomes formed by a complex of histone proteins and DNA, which allows the packaging of DNA into the nucleus. The less condensed euchromatin represents transcriptionally active regions, while heterochromatin is usually inactive (Vaillant and Paszkowski, 2007). Chromatin state is known to be influenced by both DNA methylation and histone modifications which in turn impact gene expression and the structure of chromosomes. In a recent study, the role of chromatin modifications during plant reproduction elucidated 3-dimensional chromosome reorganization mediated by histones and DNA methylation (Dukowic-Schulze et al. 2017). In addition, gibberellins have been shown in increasing the level of histone acetylation, which affects regions of chromatin involved in maize seed germination (Zheng et al. 2017). Another study reports a novel function of a tomato histone deacetylase gene in the regulation of fruit ripening (Guo et al. 2017).</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/cherry-tomato-common-grape-vine-ripening-fruit-vegetable-cherry-tomatoes.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <p>In addition, multigene families encode transcription factors, with members found throughout the genome or clustered on the same chromosome. Numerous DNA binding proteins that interact with plant promoters have been identified -- some are similar to well-characterized transcription factors in animals or yeast, while others are unique to plants. For example, diverse members of the subfamily X of the plant-specific ethylene response factor (ERF) transcription factors coordinate stress signaling with wound repair activation. Tissue repair is also enhanced through a protein complex of ERF and GRAS TFs (Heyman et. al,.2018). A compilation of known plant transcription factors can be found in the plant transcription factor database at http://plntfdb.bio.uni-potsdam.de/v3.0/.</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/rna-strand.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <h3 style="font-weight: 100; margin-top: 0;">RNA</h3> <p>Recent research shows that a number of classes of small RNAs are key epigenetic regulators. In many cases, small RNAs have been implicated in DNA methylation and chromatin modification (Meyer, 2015). In addition, the role of small RNAs has been implicated in plant stress tolerance (Kumar et al., 2017). López-Galiano et al also provided insight into a coordinated function of a miRNA gene and histone modifications in regulating the expression of a WRKY transcription factor in response to stress.</p> <p>RNA interference (RNAi) is another epigenetic mechanism that leads to small RNA generation, which mediates gene silencing at the post-transcriptional level. RNAi technology has immense potential for plant disease resistance.</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/dna-methylation.jpg" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <h3 style="font-weight: 100; margin-top: 0;">DNA methylation</h3> <p>Plants, unlike animals, have three sites that can be methylated G, CHG (H can be A, C, T), and CHH (Law and Jacobsen, 2010). DNA methylation has attracted particular interest. In Arabidopsis, one-third of methylated genes occur in transcribed regions, and 5% of genes are methylated in promoter regions, suggesting that many of these are epigenetically regulated. (Zhang et al., 2006).</p> <p>There are thousands of differentially methylated regions (DMRs) that influence phenotype by influencing gene expression. The analysis of epigenetic recombinant inbred line (epiRIL) plants from Arabidopsis points to the evidence of the influence of DMRs. An epiRIL results from crossing two genetically identical plants with differing DNA methylation levels (with one parent as a homozygous mutant for an essential DNA methylation maintenance gene). The offspring of these plants have similar genomes that vary only in methylation levels. Many traits have been studied using epiRILs -- flowering time, plant height, and response to abiotic stress, some of which have now been mapped to DMRs (Zhang et al. 2018)</p> <p>Regulation by DNA methylation has been shown to be important in many aspects of plant development and response such as vernalization, hybrid vigor, and self-incompatibility (Itabashi et al. 2017). For example, vernalization treatments have shown reduced DNA methylation and subsequent initiation of flowering (Burn et al., 1993). Stress can also influence DNA methylation in plants as a response to environmental stimuli. (Steward et al., 2002; Song et al., 2012). A high degree of DNA methylation has also suggested the role in the improvement of plant fitness under different environmental conditions (Saéz-Laguna et al., 2014). In addition, methylation can affect normal fruit and hypomethylation predicts homeotic transformation and loss of fruit yield (Ong-Abdullah et al., 2015)</p> </div> </div> <div class="row extra-spaced"> <div class="small-12 medium-3 large-3 columns"> <p><img src="https://www.diagenode.com/img/areas/plant-development.jpg" class="left" style="padding-right: 15px;" /></p> </div> <div class="small-12 medium-9 large-9 columns"> <p>DNA demethylation has also been implied in various aspects of plant development including pollen tube formation, embryogenesis, fruit ripening, stomatal development, and nodule formation ( Li et al. 2017). Demethylation of rice genomic DNA caused an altered pattern of gene expression, inducing dwarf plants (Sano et al., 1990).</p> <p>Epigenetic modifications contribute to the stability and survival of the plants and their ability to adapt in different environmental conditions.</p> </div> </div> <h3>Diagenode products for your epigenomics research in plants</h3> <div class="row extra-spaced"> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #099f92; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/chromatin-function">Chromatin analysis</a></h3> <center><a href="https://www.diagenode.com/en/categories/chromatin-function"><img src="https://www.diagenode.com/img/cancer/chromatin-icon.png" /></a></center> <p class="text-left">Understand the role of chromatin in plant function and development</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/chromatin-function">Learn about our chromatin analysis products</a></li> <li><a href="https://www.diagenode.com/en/p/universal-plant-chip-seq-kit-x24-24-rxns"> Learn about the Universal Plant ChIP Kit</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #30415c; height: 275px;"> <h3 class="text-center"><a href="https://www.diagenode.com/en/categories/dna-methylation" style="color: #30415c;">DNA methylation</a></h3> <center><a href="https://www.diagenode.com/en/categories/dna-methylation"><img src="https://www.diagenode.com/img/cancer/dna-icon.png" /></a></center> <p class="text-left">DNA methylation and demethylation and the effects on plant response and function</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/dna-methylation">Discover DNA methylation analysis solutions at any resolution</a></li> </ul> </div> <div class="small-12 medium-4 large-4 columns text-left"> <div class="panel" style="border-color: #474546; height: 275px;"> <h3 class="text-center"><span class="darkgrey">Non-coding RNAs</span></h3> <center><img src="https://www.diagenode.com/img/cancer/non-coding-icon.png" /></center> <p class="text-left">Discover noncoding RNAs in the regulation of gene expression in plants</p> </div> <ul> <li><a href="https://www.diagenode.com/en/categories/Library-preparation-for-RNA-seq">Library prep for RNA-seq studies for ncRNAs</a></li> </ul> </div> </div> <h3>References</h3> <p><small> Burn, J. et al (1993).

Immune cells depend on the expression of specific cell-surface molecules to recognize and eliminate cancer cells. However, tumor cells can take over various epigenetic mechanisms and subsequently use epigenetic silencing to shut off this crucial expression, thereby escaping the recognition from immune cells. Epigenetic modifiers can also reactivate many silenced genes such as immune checkpoints regulators that turn on immune response.</span></p> <p>As a result, in recent years, epigenetic drugs have been a topic of keen interest for clinical researchers. These drugs include promising immunomodulatory agents that may restore expression of cell-surface molecules that allow cancer cells to once again be detectable as well as other targeting agents that trigger antitumor immune responses. Epigenetic therapies, either alone or in combination with current immunotherapies, may lead to new approaches for cancer treatment.</p> <p>The idea of combination therapy for treating cancers has become especially critical. Many patients either do not respond, become resistant, or suffer toxicities from current immunotherapy treatments alone. The combination of epigenetic therapy with common immunotherapies such as interleukin-2 therapy, adoptive T-cell transfer, and immune checkpoint inhibitors, among others are just a few of the strategies being tested with various cancer types in clinical trials. Researchers have demonstrated that combining epigenetic drugs, such as the DNA methyltransferase inhibitors 5-aza-2′-deoxycytidine and guadecitabine, with immunomodulating antibodies that target CTLA-4 or the PD-1/PDL-1 immune checkpoint improves therapeutic efficacy.</p> <p>Additionally, epigenomic signatures in immune and cancer cells may be predictors of success of immunotherapy for patients. Candidate epigenetic biomarkers may improve patient classification and personalized medicine to maximize treatment success and minimize negative effects. Potential biomarkers have been identified in the literature as predictors of the cancer response to immunotherapy such as PD-L1 expression, tumor-associated antigens (TAAs), HLA expression , tumor mutational burden and neoantigen identification , mismatch repair deficiency to name a few. The epigenetic control of these events has been validated. Epigenetic biomarkers may offer additional advantages, such as revealing information about the life habits and conditions of patients, details about the origin of the tumors, predictive indicators, and therapy-monitoring indicators.</p> </div> <h3>Diagenode products for your epigenomics research in Cancer</h3> <div class="row"> <div class="small-12 medium-4 large-4 columns text-left"> <div

Epigenetic changes such as histone modifications, </span><b>DNA methylation</b><span style="font-weight: 400;">, chromatin remodeling, and non-coding RNAs function as important regulators that alter host expression patterns. These changes have important implications to the virus itself since it relies on the host cell to replicate its genetic material and continue to proliferate.

The enzyme neutral sphingomyelinase 2 (nSMase2) is involved in the biogenesis of ceramide and extracellular vesicles (EVs), both of which are dysregulated in PLH, CI, and MDD. Here we evaluated EcoHIV-infected mice for behavioral abnormalities relevant to depression and cognition deficits, and assessed the behavioral and biochemical effects of nSMase2 inhibition. Mice were infected with EcoHIV and daily treatment with either vehicle or the nSMase2 inhibitor (R)-(1-(3-(3,4-dimethoxyphenyl)-2,6-dimethylimidazo[1,2-b]pyridazin-8-yl)pyrrolidin-3-yl)-carbamate (PDDC) began 3 weeks post-infection. After 2 weeks of treatment, mice were subjected to behavior tests. EcoHIV-infected mice exhibited behavioral abnormalities relevant to MDD and CI that were reversed by PDDC treatment. EcoHIV infection significantly increased cortical brain nSMase2 activity, resulting in trend changes in sphingomyelin and ceramide levels that were normalized by PDDC treatment. EcoHIV-infected mice also exhibited increased levels of brain-derived EVs and altered microRNA cargo, including miR-183-5p, miR-200c-3p, miR-200b-3p, and miR-429-3p, known to be associated with MDD and CI; all were normalized by PDDC. In conclusion, inhibition of nSMase2 represents a possible new therapeutic strategy for the treatment of HIV-associated CI and MDD.</p>', 'date' => '2022-07-01', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/35462006', 'doi' => '10.1016/j.nbd.2022.105734', 'modified' => '2022-08-04 15:59:55', 'created' => '2022-08-04 14:55:36', 'ProductsPublication' => array( 'id' => '5972', 'product_id' => '3045', 'publication_id' => '4375' ) ) $externalLink = ' <a href="https://www.ncbi.nlm.nih.gov/pubmed/35462006" target="_blank"><i class="fa fa-external-link"></i></a>'include - APP/View/Products/view.ctp, line 755 View::_evaluate() - CORE/Cake/View/View.php, line 971 View::_render() - CORE/Cake/View/View.php, line 933 View::render() - CORE/Cake/View/View.php, line 473 Controller::render() - CORE/Cake/Controller/Controller.php, line 963 ProductsController::slug() - APP/Controller/ProductsController.php, line 1052 ReflectionMethod::invokeArgs() - [internal], line ??
