The Infinium MethylationEPIC Array is a genome-wide DNA methylation analysis technique based on bisulfite conversion and Illumina® technology. It allows to quantitatively detect the total methylation level of over 850,000 methylations sites throughout the human genome at single nucleotide resolution. It offers comprehensive, expert-selected coverage of CpG islands, enhancer regions, open chromatin sites and other important regions of the methylome.
Briefly, upon bisulfite treatment, unmethylated cytosines (both 5mC and 5hmC) are converted to uracils, while methylated cytosines remain unchanged. Infinium HD array technology interrogates these differentiated loci using site-specific probes (designed for the methylated and unmethylated sites respectively). The level of total methylation for the interrogated locus can be determined by calculating the ratio of the fluorescent signals from the methylated vs. unmethylated sites.

Cell lines were then subjected to cellular assays with neoantigen and cancer testis antigen (CTA) specific T cells. RESULTS: We demonstrate that DAC increases neoantigen and CTA mRNA expression through DNA hypomethylation. This results in increased neoantigen presentation by MHC class I in tumour cells, leading to increased neoantigen- and CTA-specific T cell activation and killing of DAC-treated cancer cells. In addition, we show that patients have endogenous cancer-specific T cells in both tumour and blood, which show increased tumour-specific activation in the presence of DAC-treated cells.

Together, these data indicate certain discrepancy with the mechanisms described in animal models or the existence of redundant or complementary functions unforeseen in humans.</span></p>', 'date' => '2021-04-03', 'pmid' => 'https://doi.org/10.3390/ijms22073735', 'doi' => '10.3390/ijms22073735', 'modified' => '2021-06-29 14:12:51', 'created' => '2021-06-29 14:12:51', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 11 => array( 'id' => '4106', 'name' => 'Genome-wide DNA methylation and transcriptome integration reveal distinct sex differences in skeletal muscle', 'authors' => 'Shanie Landen, Macsue Jacques , Danielle Hiam , Javier Alvarez, Nicholas R Harvey, Larisa M.

However, skeletal muscle epigenetic sex differences remain largely unexplored, yet skeletal muscle displays distinct sex differences at the transcriptome level. We conducted a large-scale meta-analysis of autosomal DNA methylation sex differences in human skeletal muscle in three separate cohorts (Gene SMART, FUSION, and GSE38291), totalling n = 369 human muscle samples (n = 222 males, n = 147 females). We found 10,240 differentially methylated regions (DMRs) at FDR < 0.005, 94% of which were hypomethylated in males, and gene set enrichment analysis revealed that differentially methylated genes were involved in muscle contraction and metabolism. We then integrated our epigenetic results with transcriptomic data from the GTEx database and the FUSION cohort. Altogether, we identified 326 autosomal genes that display sex differences at both the DNA methylation, and transcriptome levels. Importantly, sex-biased genes at the transcriptional level were overrepresented among the sex-biased genes at the epigenetic level (p-value = 4.6e-13), which suggests differential DNA methylation and gene expression between males and females in muscle are functionally linked. Finally, we validated expression of three genes with large effect sizes (FOXO3A, ALDH1A1, and GGT7) in the Gene SMART cohort with qPCR. GGT7, involved in muscle metabolism, displays male-biased expression in skeletal muscle across the three cohorts, as well as lower methylation in males. In conclusion, we uncovered thousands of genes that exhibit DNA methylation differences between the males and females in human skeletal muscle that may modulate mechanisms controlling muscle metabolism and health.</span></p>', 'date' => '2021-03-17', 'pmid' => 'https://doi.org/10.1101/2021.03.16.435733', 'doi' => '10.1101/2021.03.16.435733', 'modified' => '2021-06-29 14:15:50', 'created' => '2021-06-29 14:15:50', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 12 => array( 'id' => '4358', 'name' => 'ZNF718, HOXA4, and ZFP57 are differentially methylated inperiodontitis in comparison with periodontal health: Epigenome-wide DNAmethylation pilot study.', 'authors' => 'Hernández H.G. et al.

BACKGROUND: The DNA methylation profiling of peripheral leukocytes as immune-related tissue potentially relevant as a source of biomarkers between periodontitis patients and gingivally healthy subjects has not been investigated. METHODS: A DNA methylation epigenome-wide study of peripheral leukocytes was conducted using the Illumina MethylationEPIC platform in sixteen subjects, eight diagnosed with periodontitis patients and eight age-matched and sex-matched periodontally healthy controls. A trained periodontist performed the clinical evaluation. Global DNA methylation was estimated using methylation-sensitive high-resolution melting in LINE1. Routine cell count cytometry and metabolic laboratory tests were also performed. The analysis of differentially methylated positions (DMPs) and differentially methylated regions (DMRs) was made using R/Bioconductor environment considering leukocyte populations assessed in both routine cell counts and using the FlowSorted.Blood.EPIC package. Finally, a DMP and DMR intersection analysis was performed. Functional enrichment analysis was carried out with the differentially methylated genes found in DMP. RESULTS: DMP analysis identified 81 differentially hypermethylated genes and 21 differentially hypomethylated genes. Importantly, the intersection analysis showed that zinc finger protein 718 (ZNF718) and homeobox A4 (HOXA4) were differentially hypermethylated and zinc finger protein 57 (ZFP57) was differentially hypomethylated in periodontitis. The functional enrichment analysis found clearly immune-related ontologies such as "detection of bacterium" and "antigen processing and presentation." CONCLUSION: The results of this study propose three new periodontitis-related genes: ZNF718, HOXA4, and ZFP57 but also evidence the suitability and relevance of studying leukocytes' DNA methylome for biological interpretation of systemic immune-related epigenetic patterns in periodontitis.</p>', 'date' => '2021-03-01', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/33660869', 'doi' => '10.1111/jre.12868', 'modified' => '2022-08-03 16:48:52', 'created' => '2022-05-19 10:41:50', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 13 => array( 'id' => '4590', 'name' => 'From methylation to myelination: epigenomic and transcriptomic profilingof chronic inactive demyelinated multiple sclerosis lesions', 'authors' => 'Tiane A. et al.', 'description' => '<p>Introduction In the progressive phase of multiple sclerosis (MS), the hampered differentiation capacity of oligodendrocyte precursor cells (OPCs) eventually results in remyelination failure.

Addressing the impact of age-related diseases has become a priority in healthcare practice, leading to the exploration of innovative approaches, including the development of predictors to estimate biological age (so-called “ageing clocks”). These predictors offer promising insights into the ageing process and age-related diseases. This study aims to showcase the significance of ageing clocks within a unique, deeply phenotyped longitudinal cohort.

We screened a library of annotated compounds in these cells and discovered aurora kinase inhibitors (AURKi) as strong hits. Type I IFN signaling was found to be the most enriched gene signature after AURKi treatment in HCT116, and this signature was also strongly enriched in other colorectal cancer (CRC) cell lines. The ability of AURKi to activate IFN in HCT116 was dependent on MAVS and RIG-I, but independent of STING, whose signaling is deficient in these cells. MAVS dependence was recapitulated in other CRC lines with STING pathway deficiency, whereas in cells with intact STING signaling, the STING pathway was required for IFN induction by AURKi. AURKi's were found to induce expression of endogenous retroviruses (ERV's). These ERVs were distinct from those induced by the DNA methyltransferase inhibitors (DNMTi's), which can induce IFN signaling via ERV induction, suggesting a novel mechanism of action. The anti-tumor effect of alisertib in mice was accompanied by an induction of IFN expression in HCT116 or CT26 tumors. CT26 tumor growth inhibition by alisertib was absent in NOD/SCID mice vs. WT mice, and tumors from WT mice with alisertib treatment showed increased in CD8+ T cell infiltration, suggesting that anti-tumor efficacy of AURKi depends, at least in part, on an intact immune response.</span></p>', 'date' => '2024-02-15', 'pmid' => 'https://pubmed.ncbi.nlm.nih.gov/38358346/', 'doi' => '10.1158/2767-9764.CRC-23-0432', 'modified' => '2024-02-22 12:33:11', 'created' => '2024-02-22 12:33:11', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 3 => array( 'id' => '4811', 'name' => 'Association of DNA methylation signatures with premature ageing andcardiovascular death in patients with end-stage kidney disease: a pilotepigenome-wide association study.', 'authors' => 'Sumida K. et al.', 'description' => '<p><span>Patients with end-stage kidney disease (ESKD) display features of premature aging.

We characterized the transcriptional and epigenetic landscape with the IDH2i AG-221, using an IDH2 mutated AML cell line model and AML patient cohorts, and discovered a perturbed transcriptional regulatory network involving myeloid transcription factors that were partly restored after AG-221 treatment. In addition, hypermethylation of the HLA cluster caused a down-regulation of HLA class I genes, triggering an enhanced natural killer (NK) cell activation and an increased susceptibility to NK cell-mediated responses. Finally, analyses of DNA methylation data from IDHi-treated patients showed that non-responders still harbored hypermethylation in HLA class I genes.

Among them, several distinct rare genetic diseases are linked to mutations in SMCHD1 that encodes the structural maintenance of chromosomes flexible hinge domain containing 1 chromatin-associated factor. In humans, its function as well as the impact of its mutations remains poorly defined. To fill this gap, we determined the episignature associated with heterozygous SMCHD1 variants in primary cells and cell lineages derived from induced pluripotent stem cells for Bosma arhinia and microphthalmia syndrome (BAMS) and type 2 facioscapulohumeral dystrophy (FSHD2). In human tissues, SMCHD1 regulates the distribution of methylated CpGs, H3K27 trimethylation and CTCF at repressed chromatin but also at euchromatin. Based on the exploration of tissues affected either in FSHD or in BAMS, i.e. skeletal muscle fibers and neural crest stem cells, respectively, our results emphasize multiple functions for SMCHD1, in chromatin compaction, chromatin insulation and gene regulation with variable targets or phenotypical outcomes. We concluded that in rare genetic diseases, SMCHD1 variants impact gene expression in two ways: (i) by changing the chromatin context at a number of euchromatin loci or (ii) by directly regulating some loci encoding master transcription factors required for cell fate determination and tissue differentiation.</p>', 'date' => '2023-06-01', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/37334829', 'doi' => '10.1093/nar/gkad523', 'modified' => '2023-08-01 14:35:38', 'created' => '2023-08-01 15:59:38', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 6 => array( 'id' => '4767', 'name' => 'Altered DNA methylation and gene expression predict disease severity inpatients with Aicardi-Goutières syndrome.', 'authors' => 'Garau J. et al.', 'description' => '<p>Aicardi-Goutières Syndrome (AGS) is a rare neuro-inflammatory disease characterized by increased expression of interferon-stimulated genes (ISGs).

Methods: Transcriptomic and DNA methylation landscapes in 25 high- and low-risk UMs were interrogated by Agilent SurePrint G3 Human Gene Expression 8x60K v2 Microarray and Human Infinium Methylation EPIC Bead Chip array, respectively. DNA methylation and gene expression of the nine top discriminatory genes, selected by the integrative analysis, were validated by pyrosequencing and qPCR in 58 tissues. Results: Among 2,262 differentially expressed genes discovered in UM samples differing in metastatic risk, 60 were epigenetic regulators, mostly histone modifiers and chromatin remodelers. A total of 44,398 CpGs were differentially methylated, 27,810 hypomethylated, and 16,588 hypermethylated in high-risk tumors, with delta beta values ranging between -0.78 and 0.79. By integrative analysis, 944 differentially expressed DNA methylation-regulated genes were revealed, 635 hypomethylated/upregulated, and 309 hypermethylated/downregulated. Aberrant DNA methylation in high-risk tumors was associated with the deregulation of key oncogenic pathways such as EGFR tyrosine kinase inhibitor resistance, focal adhesion, proteoglycans in cancer, PI3K-Akt signaling, or ECM-receptor interaction. Notably, the DNA methylation values of nine genes, HTR2B , AHNAK2, CALHM2, SLC25A38, EDNRB, TLR1, RNF43, IL12RB2 , and MEGF10, validated by pyrosequencing, demonstrated excellent risk group prediction accuracies (AUCs ranging between 0.870 and 0.956). Moreover, CALHM2 hypomethylation and MEGF10, TLR1 hypermethylation, as well as two three-gene methylation signatures, Signature 1 combining A HNAK2, CALHM2, and IL12RB and Signature 2 A HNAK2, CALHM2, and SLC25A38 genes, correlated with shorter overall survival (HR = 4.38, 95\% CI 1.30-16.41, HR = 5.59, 95\% CI 1.30-16.41; HR = 3.43, 95\% CI 1.30-16.41, HR = 4.61, 95\% CI 1.30-16.41 and HR = 4.95, 95\% CI 1.39-17.58, respectively). Conclusions: Our results demonstrate a significant role of DNA methylation aberrancy in UM progression.

Despite maximal treatment, median survival remains dismal at 14-24 months. Immunotherapies, such as checkpoint inhibition, have revolutionised management of some cancers but have little benefit for GBM patients. This is, in part, due to the low mutational and neoantigen burden in this immunogenically 'cold' tumour. METHODS: U87MG and patient derived cell lines were treated with 5-aza-2'-deoxycytidine (DAC) and underwent whole exome and transcriptome sequencing. Cell lines were then subjected to cellular assays with neoantigen and cancer testis antigen (CTA) specific T cells. RESULTS: We demonstrate that DAC increases neoantigen and CTA mRNA expression through DNA hypomethylation. This results in increased neoantigen presentation by MHC class I in tumour cells, leading to increased neoantigen- and CTA-specific T cell activation and killing of DAC-treated cancer cells. In addition, we show that patients have endogenous cancer-specific T cells in both tumour and blood, which show increased tumour-specific activation in the presence of DAC-treated cells. CONCLUSIONS: Our work shows that DAC increases GBM immunogenicity and consequent susceptibility to T cell responses in-vitro.

Here, we present comparative methylomes from patients with mutations in the de novo DNA methyltransferases DNMT3A and DNMT3B, in their catalytic domain or their N-terminal parts involved in reading histone methylation, or in histone H3 lysine (K) methylases NSD1 or SETD2 (H3 K36) or KMT2D/MLL2 (H3 K4). We provide disease-specific DNAme signatures and document the distinct consequences of mutations in enzymes with very similar or intertwined functions, including at repeated sequences and imprinted loci. We found that KMT2D and SETD2 germline mutations have little impact on DNAme profiles. In contrast, the overlapping DNAme alterations downstream of NSD1 or DNMT3 mutations underlines functional links, more specifically between NSD1 and DNMT3B at heterochromatin regions or DNMT3A at regulatory elements.

However, skeletal muscle epigenetic sex differences remain largely unexplored, yet skeletal muscle displays distinct sex differences at the transcriptome level. We conducted a large-scale meta-analysis of autosomal DNA methylation sex differences in human skeletal muscle in three separate cohorts (Gene SMART, FUSION, and GSE38291), totalling n = 369 human muscle samples (n = 222 males, n = 147 females). We found 10,240 differentially methylated regions (DMRs) at FDR < 0.005, 94% of which were hypomethylated in males, and gene set enrichment analysis revealed that differentially methylated genes were involved in muscle contraction and metabolism. We then integrated our epigenetic results with transcriptomic data from the GTEx database and the FUSION cohort. Altogether, we identified 326 autosomal genes that display sex differences at both the DNA methylation, and transcriptome levels. Importantly, sex-biased genes at the transcriptional level were overrepresented among the sex-biased genes at the epigenetic level (p-value = 4.6e-13), which suggests differential DNA methylation and gene expression between males and females in muscle are functionally linked. Finally, we validated expression of three genes with large effect sizes (FOXO3A, ALDH1A1, and GGT7) in the Gene SMART cohort with qPCR. GGT7, involved in muscle metabolism, displays male-biased expression in skeletal muscle across the three cohorts, as well as lower methylation in males. In conclusion, we uncovered thousands of genes that exhibit DNA methylation differences between the males and females in human skeletal muscle that may modulate mechanisms controlling muscle metabolism and health.</span></p>', 'date' => '2021-03-17', 'pmid' => 'https://doi.org/10.1101/2021.03.16.435733', 'doi' => '10.1101/2021.03.16.435733', 'modified' => '2021-06-29 14:15:50', 'created' => '2021-06-29 14:15:50', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 12 => array( 'id' => '4358', 'name' => 'ZNF718, HOXA4, and ZFP57 are differentially methylated inperiodontitis in comparison with periodontal health: Epigenome-wide DNAmethylation pilot study.', 'authors' => 'Hernández H.G. et al.

BACKGROUND: The DNA methylation profiling of peripheral leukocytes as immune-related tissue potentially relevant as a source of biomarkers between periodontitis patients and gingivally healthy subjects has not been investigated. METHODS: A DNA methylation epigenome-wide study of peripheral leukocytes was conducted using the Illumina MethylationEPIC platform in sixteen subjects, eight diagnosed with periodontitis patients and eight age-matched and sex-matched periodontally healthy controls. A trained periodontist performed the clinical evaluation. Global DNA methylation was estimated using methylation-sensitive high-resolution melting in LINE1. Routine cell count cytometry and metabolic laboratory tests were also performed. The analysis of differentially methylated positions (DMPs) and differentially methylated regions (DMRs) was made using R/Bioconductor environment considering leukocyte populations assessed in both routine cell counts and using the FlowSorted.Blood.EPIC package. Finally, a DMP and DMR intersection analysis was performed. Functional enrichment analysis was carried out with the differentially methylated genes found in DMP. RESULTS: DMP analysis identified 81 differentially hypermethylated genes and 21 differentially hypomethylated genes. Importantly, the intersection analysis showed that zinc finger protein 718 (ZNF718) and homeobox A4 (HOXA4) were differentially hypermethylated and zinc finger protein 57 (ZFP57) was differentially hypomethylated in periodontitis. The functional enrichment analysis found clearly immune-related ontologies such as "detection of bacterium" and "antigen processing and presentation." CONCLUSION: The results of this study propose three new periodontitis-related genes: ZNF718, HOXA4, and ZFP57 but also evidence the suitability and relevance of studying leukocytes' DNA methylome for biological interpretation of systemic immune-related epigenetic patterns in periodontitis.</p>', 'date' => '2021-03-01', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/33660869', 'doi' => '10.1111/jre.12868', 'modified' => '2022-08-03 16:48:52', 'created' => '2022-05-19 10:41:50', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 13 => array( 'id' => '4590', 'name' => 'From methylation to myelination: epigenomic and transcriptomic profilingof chronic inactive demyelinated multiple sclerosis lesions', 'authors' => 'Tiane A. et al.', 'description' => '<p>Introduction In the progressive phase of multiple sclerosis (MS), the hampered differentiation capacity of oligodendrocyte precursor cells (OPCs) eventually results in remyelination failure.

Cell lines were then subjected to cellular assays with neoantigen and cancer testis antigen (CTA) specific T cells. RESULTS: We demonstrate that DAC increases neoantigen and CTA mRNA expression through DNA hypomethylation. This results in increased neoantigen presentation by MHC class I in tumour cells, leading to increased neoantigen- and CTA-specific T cell activation and killing of DAC-treated cancer cells. In addition, we show that patients have endogenous cancer-specific T cells in both tumour and blood, which show increased tumour-specific activation in the presence of DAC-treated cells.

Together, these data indicate certain discrepancy with the mechanisms described in animal models or the existence of redundant or complementary functions unforeseen in humans.</span></p>', 'date' => '2021-04-03', 'pmid' => 'https://doi.org/10.3390/ijms22073735', 'doi' => '10.3390/ijms22073735', 'modified' => '2021-06-29 14:12:51', 'created' => '2021-06-29 14:12:51', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 11 => array( 'id' => '4106', 'name' => 'Genome-wide DNA methylation and transcriptome integration reveal distinct sex differences in skeletal muscle', 'authors' => 'Shanie Landen, Macsue Jacques , Danielle Hiam , Javier Alvarez, Nicholas R Harvey, Larisa M.

However, skeletal muscle epigenetic sex differences remain largely unexplored, yet skeletal muscle displays distinct sex differences at the transcriptome level. We conducted a large-scale meta-analysis of autosomal DNA methylation sex differences in human skeletal muscle in three separate cohorts (Gene SMART, FUSION, and GSE38291), totalling n = 369 human muscle samples (n = 222 males, n = 147 females). We found 10,240 differentially methylated regions (DMRs) at FDR < 0.005, 94% of which were hypomethylated in males, and gene set enrichment analysis revealed that differentially methylated genes were involved in muscle contraction and metabolism. We then integrated our epigenetic results with transcriptomic data from the GTEx database and the FUSION cohort. Altogether, we identified 326 autosomal genes that display sex differences at both the DNA methylation, and transcriptome levels. Importantly, sex-biased genes at the transcriptional level were overrepresented among the sex-biased genes at the epigenetic level (p-value = 4.6e-13), which suggests differential DNA methylation and gene expression between males and females in muscle are functionally linked. Finally, we validated expression of three genes with large effect sizes (FOXO3A, ALDH1A1, and GGT7) in the Gene SMART cohort with qPCR. GGT7, involved in muscle metabolism, displays male-biased expression in skeletal muscle across the three cohorts, as well as lower methylation in males. In conclusion, we uncovered thousands of genes that exhibit DNA methylation differences between the males and females in human skeletal muscle that may modulate mechanisms controlling muscle metabolism and health.</span></p>', 'date' => '2021-03-17', 'pmid' => 'https://doi.org/10.1101/2021.03.16.435733', 'doi' => '10.1101/2021.03.16.435733', 'modified' => '2021-06-29 14:15:50', 'created' => '2021-06-29 14:15:50', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 12 => array( 'id' => '4358', 'name' => 'ZNF718, HOXA4, and ZFP57 are differentially methylated inperiodontitis in comparison with periodontal health: Epigenome-wide DNAmethylation pilot study.', 'authors' => 'Hernández H.G. et al.

BACKGROUND: The DNA methylation profiling of peripheral leukocytes as immune-related tissue potentially relevant as a source of biomarkers between periodontitis patients and gingivally healthy subjects has not been investigated. METHODS: A DNA methylation epigenome-wide study of peripheral leukocytes was conducted using the Illumina MethylationEPIC platform in sixteen subjects, eight diagnosed with periodontitis patients and eight age-matched and sex-matched periodontally healthy controls. A trained periodontist performed the clinical evaluation. Global DNA methylation was estimated using methylation-sensitive high-resolution melting in LINE1. Routine cell count cytometry and metabolic laboratory tests were also performed. The analysis of differentially methylated positions (DMPs) and differentially methylated regions (DMRs) was made using R/Bioconductor environment considering leukocyte populations assessed in both routine cell counts and using the FlowSorted.Blood.EPIC package. Finally, a DMP and DMR intersection analysis was performed. Functional enrichment analysis was carried out with the differentially methylated genes found in DMP. RESULTS: DMP analysis identified 81 differentially hypermethylated genes and 21 differentially hypomethylated genes. Importantly, the intersection analysis showed that zinc finger protein 718 (ZNF718) and homeobox A4 (HOXA4) were differentially hypermethylated and zinc finger protein 57 (ZFP57) was differentially hypomethylated in periodontitis. The functional enrichment analysis found clearly immune-related ontologies such as "detection of bacterium" and "antigen processing and presentation." CONCLUSION: The results of this study propose three new periodontitis-related genes: ZNF718, HOXA4, and ZFP57 but also evidence the suitability and relevance of studying leukocytes' DNA methylome for biological interpretation of systemic immune-related epigenetic patterns in periodontitis.</p>', 'date' => '2021-03-01', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/33660869', 'doi' => '10.1111/jre.12868', 'modified' => '2022-08-03 16:48:52', 'created' => '2022-05-19 10:41:50', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 13 => array( 'id' => '4590', 'name' => 'From methylation to myelination: epigenomic and transcriptomic profilingof chronic inactive demyelinated multiple sclerosis lesions', 'authors' => 'Tiane A. et al.', 'description' => '<p>Introduction In the progressive phase of multiple sclerosis (MS), the hampered differentiation capacity of oligodendrocyte precursor cells (OPCs) eventually results in remyelination failure.

Addressing the impact of age-related diseases has become a priority in healthcare practice, leading to the exploration of innovative approaches, including the development of predictors to estimate biological age (so-called “ageing clocks”). These predictors offer promising insights into the ageing process and age-related diseases. This study aims to showcase the significance of ageing clocks within a unique, deeply phenotyped longitudinal cohort.

We screened a library of annotated compounds in these cells and discovered aurora kinase inhibitors (AURKi) as strong hits. Type I IFN signaling was found to be the most enriched gene signature after AURKi treatment in HCT116, and this signature was also strongly enriched in other colorectal cancer (CRC) cell lines. The ability of AURKi to activate IFN in HCT116 was dependent on MAVS and RIG-I, but independent of STING, whose signaling is deficient in these cells. MAVS dependence was recapitulated in other CRC lines with STING pathway deficiency, whereas in cells with intact STING signaling, the STING pathway was required for IFN induction by AURKi. AURKi's were found to induce expression of endogenous retroviruses (ERV's). These ERVs were distinct from those induced by the DNA methyltransferase inhibitors (DNMTi's), which can induce IFN signaling via ERV induction, suggesting a novel mechanism of action. The anti-tumor effect of alisertib in mice was accompanied by an induction of IFN expression in HCT116 or CT26 tumors. CT26 tumor growth inhibition by alisertib was absent in NOD/SCID mice vs. WT mice, and tumors from WT mice with alisertib treatment showed increased in CD8+ T cell infiltration, suggesting that anti-tumor efficacy of AURKi depends, at least in part, on an intact immune response.</span></p>', 'date' => '2024-02-15', 'pmid' => 'https://pubmed.ncbi.nlm.nih.gov/38358346/', 'doi' => '10.1158/2767-9764.CRC-23-0432', 'modified' => '2024-02-22 12:33:11', 'created' => '2024-02-22 12:33:11', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 3 => array( 'id' => '4811', 'name' => 'Association of DNA methylation signatures with premature ageing andcardiovascular death in patients with end-stage kidney disease: a pilotepigenome-wide association study.', 'authors' => 'Sumida K. et al.', 'description' => '<p><span>Patients with end-stage kidney disease (ESKD) display features of premature aging.

We characterized the transcriptional and epigenetic landscape with the IDH2i AG-221, using an IDH2 mutated AML cell line model and AML patient cohorts, and discovered a perturbed transcriptional regulatory network involving myeloid transcription factors that were partly restored after AG-221 treatment. In addition, hypermethylation of the HLA cluster caused a down-regulation of HLA class I genes, triggering an enhanced natural killer (NK) cell activation and an increased susceptibility to NK cell-mediated responses. Finally, analyses of DNA methylation data from IDHi-treated patients showed that non-responders still harbored hypermethylation in HLA class I genes.

Among them, several distinct rare genetic diseases are linked to mutations in SMCHD1 that encodes the structural maintenance of chromosomes flexible hinge domain containing 1 chromatin-associated factor. In humans, its function as well as the impact of its mutations remains poorly defined. To fill this gap, we determined the episignature associated with heterozygous SMCHD1 variants in primary cells and cell lineages derived from induced pluripotent stem cells for Bosma arhinia and microphthalmia syndrome (BAMS) and type 2 facioscapulohumeral dystrophy (FSHD2). In human tissues, SMCHD1 regulates the distribution of methylated CpGs, H3K27 trimethylation and CTCF at repressed chromatin but also at euchromatin. Based on the exploration of tissues affected either in FSHD or in BAMS, i.e. skeletal muscle fibers and neural crest stem cells, respectively, our results emphasize multiple functions for SMCHD1, in chromatin compaction, chromatin insulation and gene regulation with variable targets or phenotypical outcomes. We concluded that in rare genetic diseases, SMCHD1 variants impact gene expression in two ways: (i) by changing the chromatin context at a number of euchromatin loci or (ii) by directly regulating some loci encoding master transcription factors required for cell fate determination and tissue differentiation.</p>', 'date' => '2023-06-01', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/37334829', 'doi' => '10.1093/nar/gkad523', 'modified' => '2023-08-01 14:35:38', 'created' => '2023-08-01 15:59:38', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 6 => array( 'id' => '4767', 'name' => 'Altered DNA methylation and gene expression predict disease severity inpatients with Aicardi-Goutières syndrome.', 'authors' => 'Garau J. et al.', 'description' => '<p>Aicardi-Goutières Syndrome (AGS) is a rare neuro-inflammatory disease characterized by increased expression of interferon-stimulated genes (ISGs).

Methods: Transcriptomic and DNA methylation landscapes in 25 high- and low-risk UMs were interrogated by Agilent SurePrint G3 Human Gene Expression 8x60K v2 Microarray and Human Infinium Methylation EPIC Bead Chip array, respectively. DNA methylation and gene expression of the nine top discriminatory genes, selected by the integrative analysis, were validated by pyrosequencing and qPCR in 58 tissues. Results: Among 2,262 differentially expressed genes discovered in UM samples differing in metastatic risk, 60 were epigenetic regulators, mostly histone modifiers and chromatin remodelers. A total of 44,398 CpGs were differentially methylated, 27,810 hypomethylated, and 16,588 hypermethylated in high-risk tumors, with delta beta values ranging between -0.78 and 0.79. By integrative analysis, 944 differentially expressed DNA methylation-regulated genes were revealed, 635 hypomethylated/upregulated, and 309 hypermethylated/downregulated. Aberrant DNA methylation in high-risk tumors was associated with the deregulation of key oncogenic pathways such as EGFR tyrosine kinase inhibitor resistance, focal adhesion, proteoglycans in cancer, PI3K-Akt signaling, or ECM-receptor interaction. Notably, the DNA methylation values of nine genes, HTR2B , AHNAK2, CALHM2, SLC25A38, EDNRB, TLR1, RNF43, IL12RB2 , and MEGF10, validated by pyrosequencing, demonstrated excellent risk group prediction accuracies (AUCs ranging between 0.870 and 0.956). Moreover, CALHM2 hypomethylation and MEGF10, TLR1 hypermethylation, as well as two three-gene methylation signatures, Signature 1 combining A HNAK2, CALHM2, and IL12RB and Signature 2 A HNAK2, CALHM2, and SLC25A38 genes, correlated with shorter overall survival (HR = 4.38, 95\% CI 1.30-16.41, HR = 5.59, 95\% CI 1.30-16.41; HR = 3.43, 95\% CI 1.30-16.41, HR = 4.61, 95\% CI 1.30-16.41 and HR = 4.95, 95\% CI 1.39-17.58, respectively). Conclusions: Our results demonstrate a significant role of DNA methylation aberrancy in UM progression.

Despite maximal treatment, median survival remains dismal at 14-24 months. Immunotherapies, such as checkpoint inhibition, have revolutionised management of some cancers but have little benefit for GBM patients. This is, in part, due to the low mutational and neoantigen burden in this immunogenically 'cold' tumour. METHODS: U87MG and patient derived cell lines were treated with 5-aza-2'-deoxycytidine (DAC) and underwent whole exome and transcriptome sequencing. Cell lines were then subjected to cellular assays with neoantigen and cancer testis antigen (CTA) specific T cells. RESULTS: We demonstrate that DAC increases neoantigen and CTA mRNA expression through DNA hypomethylation. This results in increased neoantigen presentation by MHC class I in tumour cells, leading to increased neoantigen- and CTA-specific T cell activation and killing of DAC-treated cancer cells. In addition, we show that patients have endogenous cancer-specific T cells in both tumour and blood, which show increased tumour-specific activation in the presence of DAC-treated cells. CONCLUSIONS: Our work shows that DAC increases GBM immunogenicity and consequent susceptibility to T cell responses in-vitro.

Here, we present comparative methylomes from patients with mutations in the de novo DNA methyltransferases DNMT3A and DNMT3B, in their catalytic domain or their N-terminal parts involved in reading histone methylation, or in histone H3 lysine (K) methylases NSD1 or SETD2 (H3 K36) or KMT2D/MLL2 (H3 K4). We provide disease-specific DNAme signatures and document the distinct consequences of mutations in enzymes with very similar or intertwined functions, including at repeated sequences and imprinted loci. We found that KMT2D and SETD2 germline mutations have little impact on DNAme profiles. In contrast, the overlapping DNAme alterations downstream of NSD1 or DNMT3 mutations underlines functional links, more specifically between NSD1 and DNMT3B at heterochromatin regions or DNMT3A at regulatory elements.

However, skeletal muscle epigenetic sex differences remain largely unexplored, yet skeletal muscle displays distinct sex differences at the transcriptome level. We conducted a large-scale meta-analysis of autosomal DNA methylation sex differences in human skeletal muscle in three separate cohorts (Gene SMART, FUSION, and GSE38291), totalling n = 369 human muscle samples (n = 222 males, n = 147 females). We found 10,240 differentially methylated regions (DMRs) at FDR < 0.005, 94% of which were hypomethylated in males, and gene set enrichment analysis revealed that differentially methylated genes were involved in muscle contraction and metabolism. We then integrated our epigenetic results with transcriptomic data from the GTEx database and the FUSION cohort. Altogether, we identified 326 autosomal genes that display sex differences at both the DNA methylation, and transcriptome levels. Importantly, sex-biased genes at the transcriptional level were overrepresented among the sex-biased genes at the epigenetic level (p-value = 4.6e-13), which suggests differential DNA methylation and gene expression between males and females in muscle are functionally linked. Finally, we validated expression of three genes with large effect sizes (FOXO3A, ALDH1A1, and GGT7) in the Gene SMART cohort with qPCR. GGT7, involved in muscle metabolism, displays male-biased expression in skeletal muscle across the three cohorts, as well as lower methylation in males. In conclusion, we uncovered thousands of genes that exhibit DNA methylation differences between the males and females in human skeletal muscle that may modulate mechanisms controlling muscle metabolism and health.</span></p>', 'date' => '2021-03-17', 'pmid' => 'https://doi.org/10.1101/2021.03.16.435733', 'doi' => '10.1101/2021.03.16.435733', 'modified' => '2021-06-29 14:15:50', 'created' => '2021-06-29 14:15:50', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 12 => array( 'id' => '4358', 'name' => 'ZNF718, HOXA4, and ZFP57 are differentially methylated inperiodontitis in comparison with periodontal health: Epigenome-wide DNAmethylation pilot study.', 'authors' => 'Hernández H.G. et al.

BACKGROUND: The DNA methylation profiling of peripheral leukocytes as immune-related tissue potentially relevant as a source of biomarkers between periodontitis patients and gingivally healthy subjects has not been investigated. METHODS: A DNA methylation epigenome-wide study of peripheral leukocytes was conducted using the Illumina MethylationEPIC platform in sixteen subjects, eight diagnosed with periodontitis patients and eight age-matched and sex-matched periodontally healthy controls. A trained periodontist performed the clinical evaluation. Global DNA methylation was estimated using methylation-sensitive high-resolution melting in LINE1. Routine cell count cytometry and metabolic laboratory tests were also performed. The analysis of differentially methylated positions (DMPs) and differentially methylated regions (DMRs) was made using R/Bioconductor environment considering leukocyte populations assessed in both routine cell counts and using the FlowSorted.Blood.EPIC package. Finally, a DMP and DMR intersection analysis was performed. Functional enrichment analysis was carried out with the differentially methylated genes found in DMP. RESULTS: DMP analysis identified 81 differentially hypermethylated genes and 21 differentially hypomethylated genes. Importantly, the intersection analysis showed that zinc finger protein 718 (ZNF718) and homeobox A4 (HOXA4) were differentially hypermethylated and zinc finger protein 57 (ZFP57) was differentially hypomethylated in periodontitis. The functional enrichment analysis found clearly immune-related ontologies such as "detection of bacterium" and "antigen processing and presentation." CONCLUSION: The results of this study propose three new periodontitis-related genes: ZNF718, HOXA4, and ZFP57 but also evidence the suitability and relevance of studying leukocytes' DNA methylome for biological interpretation of systemic immune-related epigenetic patterns in periodontitis.</p>', 'date' => '2021-03-01', 'pmid' => 'https://www.ncbi.nlm.nih.gov/pubmed/33660869', 'doi' => '10.1111/jre.12868', 'modified' => '2022-08-03 16:48:52', 'created' => '2022-05-19 10:41:50', 'ProductsPublication' => array( [maximum depth reached] ) ), (int) 13 => array( 'id' => '4590', 'name' => 'From methylation to myelination: epigenomic and transcriptomic profilingof chronic inactive demyelinated multiple sclerosis lesions', 'authors' => 'Tiane A. et al.', 'description' => '<p>Introduction In the progressive phase of multiple sclerosis (MS), the hampered differentiation capacity of oligodendrocyte precursor cells (OPCs) eventually results in remyelination failure.
