<p style="text-align: justify;">CATS relies on polynucleotide tailing for capturing the 3’-ends of nucleic acids and the template switching ability of MMLV-RT to capture the 5’ ends for cDNA synthesis. This kit allows for generating Illumina compatible ready-to-sequence libraries from <strong>RNA inputs as low as 100 picograms</strong> of polyA selected material in just few hours.</p>
<p style="text-align: justify;">Libraries retain <strong>strand specificity</strong> of origin. Unlike competing solutions, our CATS RNA-seq kit exhibits <strong>higher library efficiency</strong> versus ligation-based methods providing <strong>higher complexity</strong> from better template capture and minimal bias due to <strong>lower amplification</strong> requirements.</p>

'description' => '<p>: There is no standard chemotherapy for refractory or relapsing malignant pleural mesothelioma (MPM). Our previous reports nevertheless indicated that a combination of an anthracycline (doxorubicin) and a lysine deacetylase inhibitor (valproic acid, VPA) synergize to induce the apoptosis of MPM cells and reduce tumor growth in mouse models. A Phase I/II clinical trial indicated that this regimen is a promising therapeutic option for a proportion of MPM patients. : The transcriptomes of mesothelioma cells were compared after Illumina HiSeq 4000 sequencing. The expression of differentially expressed genes was inhibited by RNA interference. Apoptosis was determined by cell cycle analysis and Annexin V/7-AAD labeling. Protein expression was assessed by immunoblotting. Preclinical efficacy was evaluated in BALB/c and NOD-SCID mice. : To understand the mechanisms involved in chemoresistance, the transcriptomes of two MPM cell lines displaying different responses to VPA-doxorubicin were compared. Among the differentially expressed genes, transforming growth factor alpha (TGFα) was associated with resistance to this regimen. The silencing of TGFα by RNA interference correlated with a significant increase in apoptosis, whereas the overexpression of TGFα desensitized MPM cells to the apoptosis induced by VPA and doxorubicin. The multi-targeted inhibition of histone deacetylase (HDAC), HER2 and TGFα receptor (epidermal growth factor receptor/EGFR) improved treatment efficacy in vitro and reduced tumor growth in two MPM mouse models. Finally, TGFα expression but not EGFR correlated with patient survival. : Our data show that TGFα but not its receptor EGFR is a key factor in resistance to MPM chemotherapy. This observation may contribute to casting light on the promising but still controversial role of EGFR signaling in MPM therapy.</p>',

'description' => '<p>BACKGROUND: ARID1A (AT-rich interactive domain-containing protein 1A) is a subunit of the BAF chromatin remodeling complex and plays roles in transcriptional regulation and DNA damage response. Mutations in ARID1A that lead to inactivation or loss of expression are frequent and widespread across many cancer types including colorectal cancer (CRC). A tumor suppressor role of ARID1A has been established in a number of tumor types including CRC where the genetic inactivation of Arid1a alone led to the formation of invasive colorectal adenocarcinomas in mice. Mechanistically, ARID1A has been described to largely function through the regulation of enhancer activity. METHODS: To mimic ARID1A-deficient colorectal cancer, we used CRISPR/Cas9-mediated gene editing to inactivate the ARID1A gene in established colorectal cancer cell lines. We integrated gene expression analyses with genome-wide ARID1A occupancy and epigenomic mapping data to decipher ARID1A-dependent transcriptional regulatory mechanisms. RESULTS: Interestingly, we found that CRC cell lines harboring KRAS mutations are critically dependent on ARID1A function. In the absence of ARID1A, proliferation of these cell lines is severely impaired, suggesting an essential role for ARID1A in this context. Mechanistically, we showed that ARID1A acts as a co-factor at enhancers occupied by AP1 transcription factors acting downstream of the MEK/ERK pathway. Consistently, loss of ARID1A led to a disruption of KRAS/AP1-dependent enhancer activity, accompanied by a downregulation of expression of the associated target genes. CONCLUSIONS: We identify a previously unknown context-dependent tumor-supporting function of ARID1A in CRC downstream of KRAS signaling. Upon the loss of ARID1A in KRAS-mutated cells, enhancers that are co-occupied by ARID1A and the AP1 transcription factors become inactive, thereby leading to decreased target gene expression. Thus, targeting of the BAF complex in KRAS-mutated CRC may offer a unique, previously unknown, context-dependent therapeutic option in CRC.</p>',

<p style="text-align: justify;">CATS relies on polynucleotide tailing for capturing the 3’-ends of nucleic acids and the template switching ability of MMLV-RT to capture the 5’ ends for cDNA synthesis. This kit allows for generating Illumina compatible ready-to-sequence libraries from <strong>RNA inputs as low as 100 picograms</strong> of polyA selected material in just few hours.</p>
<p style="text-align: justify;">Libraries retain <strong>strand specificity</strong> of origin.

'description' => '<p>BACKGROUND: ARID1A (AT-rich interactive domain-containing protein 1A) is a subunit of the BAF chromatin remodeling complex and plays roles in transcriptional regulation and DNA damage response. Mutations in ARID1A that lead to inactivation or loss of expression are frequent and widespread across many cancer types including colorectal cancer (CRC). A tumor suppressor role of ARID1A has been established in a number of tumor types including CRC where the genetic inactivation of Arid1a alone led to the formation of invasive colorectal adenocarcinomas in mice. Mechanistically, ARID1A has been described to largely function through the regulation of enhancer activity. METHODS: To mimic ARID1A-deficient colorectal cancer, we used CRISPR/Cas9-mediated gene editing to inactivate the ARID1A gene in established colorectal cancer cell lines. We integrated gene expression analyses with genome-wide ARID1A occupancy and epigenomic mapping data to decipher ARID1A-dependent transcriptional regulatory mechanisms. RESULTS: Interestingly, we found that CRC cell lines harboring KRAS mutations are critically dependent on ARID1A function. In the absence of ARID1A, proliferation of these cell lines is severely impaired, suggesting an essential role for ARID1A in this context. Mechanistically, we showed that ARID1A acts as a co-factor at enhancers occupied by AP1 transcription factors acting downstream of the MEK/ERK pathway. Consistently, loss of ARID1A led to a disruption of KRAS/AP1-dependent enhancer activity, accompanied by a downregulation of expression of the associated target genes. CONCLUSIONS: We identify a previously unknown context-dependent tumor-supporting function of ARID1A in CRC downstream of KRAS signaling. Upon the loss of ARID1A in KRAS-mutated cells, enhancers that are co-occupied by ARID1A and the AP1 transcription factors become inactive, thereby leading to decreased target gene expression. Thus, targeting of the BAF complex in KRAS-mutated CRC may offer a unique, previously unknown, context-dependent therapeutic option in CRC.</p>',

<p style="text-align: justify;">CATS relies on polynucleotide tailing for capturing the 3’-ends of nucleic acids and the template switching ability of MMLV-RT to capture the 5’ ends for cDNA synthesis. This kit allows for generating Illumina compatible ready-to-sequence libraries from <strong>RNA inputs as low as 100 picograms</strong> of polyA selected material in just few hours.</p>
<p style="text-align: justify;">Libraries retain <strong>strand specificity</strong> of origin. Unlike competing solutions, our CATS RNA-seq kit exhibits <strong>higher library efficiency</strong> versus ligation-based methods providing <strong>higher complexity</strong> from better template capture and minimal bias due to <strong>lower amplification</strong> requirements.</p>

<div class="content" id="more">
<p style="text-align: justify;">CATS relies on polynucleotide tailing for capturing the 3’-ends of nucleic acids and the template switching ability of MMLV-RT to capture the 5’ ends for cDNA synthesis. This kit allows for generating Illumina compatible ready-to-sequence libraries from <strong>RNA inputs as low as 100 picograms</strong> of polyA selected material in just few hours.</p>
<p style="text-align: justify;">Libraries retain <strong>strand specificity</strong> of origin. Unlike competing solutions, our CATS RNA-seq kit exhibits <strong>higher library efficiency</strong> versus ligation-based methods providing <strong>higher complexity</strong> from better template capture and minimal bias due to <strong>lower amplification</strong> requirements.</p>

'description' => '<p>: There is no standard chemotherapy for refractory or relapsing malignant pleural mesothelioma (MPM). Our previous reports nevertheless indicated that a combination of an anthracycline (doxorubicin) and a lysine deacetylase inhibitor (valproic acid, VPA) synergize to induce the apoptosis of MPM cells and reduce tumor growth in mouse models. A Phase I/II clinical trial indicated that this regimen is a promising therapeutic option for a proportion of MPM patients. : The transcriptomes of mesothelioma cells were compared after Illumina HiSeq 4000 sequencing. The expression of differentially expressed genes was inhibited by RNA interference. Apoptosis was determined by cell cycle analysis and Annexin V/7-AAD labeling. Protein expression was assessed by immunoblotting. Preclinical efficacy was evaluated in BALB/c and NOD-SCID mice. : To understand the mechanisms involved in chemoresistance, the transcriptomes of two MPM cell lines displaying different responses to VPA-doxorubicin were compared. Among the differentially expressed genes, transforming growth factor alpha (TGFα) was associated with resistance to this regimen. The silencing of TGFα by RNA interference correlated with a significant increase in apoptosis, whereas the overexpression of TGFα desensitized MPM cells to the apoptosis induced by VPA and doxorubicin. The multi-targeted inhibition of histone deacetylase (HDAC), HER2 and TGFα receptor (epidermal growth factor receptor/EGFR) improved treatment efficacy in vitro and reduced tumor growth in two MPM mouse models. Finally, TGFα expression but not EGFR correlated with patient survival. : Our data show that TGFα but not its receptor EGFR is a key factor in resistance to MPM chemotherapy. This observation may contribute to casting light on the promising but still controversial role of EGFR signaling in MPM therapy.</p>',

'description' => '<p>BACKGROUND: ARID1A (AT-rich interactive domain-containing protein 1A) is a subunit of the BAF chromatin remodeling complex and plays roles in transcriptional regulation and DNA damage response. Mutations in ARID1A that lead to inactivation or loss of expression are frequent and widespread across many cancer types including colorectal cancer (CRC). A tumor suppressor role of ARID1A has been established in a number of tumor types including CRC where the genetic inactivation of Arid1a alone led to the formation of invasive colorectal adenocarcinomas in mice. Mechanistically, ARID1A has been described to largely function through the regulation of enhancer activity. METHODS: To mimic ARID1A-deficient colorectal cancer, we used CRISPR/Cas9-mediated gene editing to inactivate the ARID1A gene in established colorectal cancer cell lines. We integrated gene expression analyses with genome-wide ARID1A occupancy and epigenomic mapping data to decipher ARID1A-dependent transcriptional regulatory mechanisms. RESULTS: Interestingly, we found that CRC cell lines harboring KRAS mutations are critically dependent on ARID1A function. In the absence of ARID1A, proliferation of these cell lines is severely impaired, suggesting an essential role for ARID1A in this context. Mechanistically, we showed that ARID1A acts as a co-factor at enhancers occupied by AP1 transcription factors acting downstream of the MEK/ERK pathway. Consistently, loss of ARID1A led to a disruption of KRAS/AP1-dependent enhancer activity, accompanied by a downregulation of expression of the associated target genes. CONCLUSIONS: We identify a previously unknown context-dependent tumor-supporting function of ARID1A in CRC downstream of KRAS signaling. Upon the loss of ARID1A in KRAS-mutated cells, enhancers that are co-occupied by ARID1A and the AP1 transcription factors become inactive, thereby leading to decreased target gene expression. Thus, targeting of the BAF complex in KRAS-mutated CRC may offer a unique, previously unknown, context-dependent therapeutic option in CRC.</p>',

<p style="text-align: justify;">CATS relies on polynucleotide tailing for capturing the 3’-ends of nucleic acids and the template switching ability of MMLV-RT to capture the 5’ ends for cDNA synthesis. This kit allows for generating Illumina compatible ready-to-sequence libraries from <strong>RNA inputs as low as 100 picograms</strong> of polyA selected material in just few hours.</p>
<p style="text-align: justify;">Libraries retain <strong>strand specificity</strong> of origin. Unlike competing solutions, our CATS RNA-seq kit exhibits <strong>higher library efficiency</strong> versus ligation-based methods providing <strong>higher complexity</strong> from better template capture and minimal bias due to <strong>lower amplification</strong> requirements.</p>

'description' => '<p>BACKGROUND: ARID1A (AT-rich interactive domain-containing protein 1A) is a subunit of the BAF chromatin remodeling complex and plays roles in transcriptional regulation and DNA damage response. Mutations in ARID1A that lead to inactivation or loss of expression are frequent and widespread across many cancer types including colorectal cancer (CRC). A tumor suppressor role of ARID1A has been established in a number of tumor types including CRC where the genetic inactivation of Arid1a alone led to the formation of invasive colorectal adenocarcinomas in mice. Mechanistically, ARID1A has been described to largely function through the regulation of enhancer activity. METHODS: To mimic ARID1A-deficient colorectal cancer, we used CRISPR/Cas9-mediated gene editing to inactivate the ARID1A gene in established colorectal cancer cell lines. We integrated gene expression analyses with genome-wide ARID1A occupancy and epigenomic mapping data to decipher ARID1A-dependent transcriptional regulatory mechanisms. RESULTS: Interestingly, we found that CRC cell lines harboring KRAS mutations are critically dependent on ARID1A function. In the absence of ARID1A, proliferation of these cell lines is severely impaired, suggesting an essential role for ARID1A in this context. Mechanistically, we showed that ARID1A acts as a co-factor at enhancers occupied by AP1 transcription factors acting downstream of the MEK/ERK pathway. Consistently, loss of ARID1A led to a disruption of KRAS/AP1-dependent enhancer activity, accompanied by a downregulation of expression of the associated target genes. CONCLUSIONS: We identify a previously unknown context-dependent tumor-supporting function of ARID1A in CRC downstream of KRAS signaling. Upon the loss of ARID1A in KRAS-mutated cells, enhancers that are co-occupied by ARID1A and the AP1 transcription factors become inactive, thereby leading to decreased target gene expression. Thus, targeting of the BAF complex in KRAS-mutated CRC may offer a unique, previously unknown, context-dependent therapeutic option in CRC.</p>',

<p style="text-align: justify;">CATS relies on polynucleotide tailing for capturing the 3’-ends of nucleic acids and the template switching ability of MMLV-RT to capture the 5’ ends for cDNA synthesis. This kit allows for generating Illumina compatible ready-to-sequence libraries from <strong>RNA inputs as low as 100 picograms</strong> of polyA selected material in just few hours.</p>
<p style="text-align: justify;">Libraries retain <strong>strand specificity</strong> of origin. Unlike competing solutions, our CATS RNA-seq kit exhibits <strong>higher library efficiency</strong> versus ligation-based methods providing <strong>higher complexity</strong> from better template capture and minimal bias due to <strong>lower amplification</strong> requirements.</p>

<div class="content" id="more">
<p style="text-align: justify;">CATS relies on polynucleotide tailing for capturing the 3’-ends of nucleic acids and the template switching ability of MMLV-RT to capture the 5’ ends for cDNA synthesis. This kit allows for generating Illumina compatible ready-to-sequence libraries from <strong>RNA inputs as low as 100 picograms</strong> of polyA selected material in just few hours.</p>
<p style="text-align: justify;">Libraries retain <strong>strand specificity</strong> of origin. Unlike competing solutions, our CATS RNA-seq kit exhibits <strong>higher library efficiency</strong> versus ligation-based methods providing <strong>higher complexity</strong> from better template capture and minimal bias due to <strong>lower amplification</strong> requirements.</p>

'description' => '<p>: There is no standard chemotherapy for refractory or relapsing malignant pleural mesothelioma (MPM). Our previous reports nevertheless indicated that a combination of an anthracycline (doxorubicin) and a lysine deacetylase inhibitor (valproic acid, VPA) synergize to induce the apoptosis of MPM cells and reduce tumor growth in mouse models. A Phase I/II clinical trial indicated that this regimen is a promising therapeutic option for a proportion of MPM patients. : The transcriptomes of mesothelioma cells were compared after Illumina HiSeq 4000 sequencing. The expression of differentially expressed genes was inhibited by RNA interference. Apoptosis was determined by cell cycle analysis and Annexin V/7-AAD labeling. Protein expression was assessed by immunoblotting. Preclinical efficacy was evaluated in BALB/c and NOD-SCID mice. : To understand the mechanisms involved in chemoresistance, the transcriptomes of two MPM cell lines displaying different responses to VPA-doxorubicin were compared. Among the differentially expressed genes, transforming growth factor alpha (TGFα) was associated with resistance to this regimen. The silencing of TGFα by RNA interference correlated with a significant increase in apoptosis, whereas the overexpression of TGFα desensitized MPM cells to the apoptosis induced by VPA and doxorubicin. The multi-targeted inhibition of histone deacetylase (HDAC), HER2 and TGFα receptor (epidermal growth factor receptor/EGFR) improved treatment efficacy in vitro and reduced tumor growth in two MPM mouse models. Finally, TGFα expression but not EGFR correlated with patient survival. : Our data show that TGFα but not its receptor EGFR is a key factor in resistance to MPM chemotherapy. This observation may contribute to casting light on the promising but still controversial role of EGFR signaling in MPM therapy.</p>',

'description' => '<p>BACKGROUND: ARID1A (AT-rich interactive domain-containing protein 1A) is a subunit of the BAF chromatin remodeling complex and plays roles in transcriptional regulation and DNA damage response. Mutations in ARID1A that lead to inactivation or loss of expression are frequent and widespread across many cancer types including colorectal cancer (CRC). A tumor suppressor role of ARID1A has been established in a number of tumor types including CRC where the genetic inactivation of Arid1a alone led to the formation of invasive colorectal adenocarcinomas in mice. Mechanistically, ARID1A has been described to largely function through the regulation of enhancer activity. METHODS: To mimic ARID1A-deficient colorectal cancer, we used CRISPR/Cas9-mediated gene editing to inactivate the ARID1A gene in established colorectal cancer cell lines. We integrated gene expression analyses with genome-wide ARID1A occupancy and epigenomic mapping data to decipher ARID1A-dependent transcriptional regulatory mechanisms. RESULTS: Interestingly, we found that CRC cell lines harboring KRAS mutations are critically dependent on ARID1A function. In the absence of ARID1A, proliferation of these cell lines is severely impaired, suggesting an essential role for ARID1A in this context. Mechanistically, we showed that ARID1A acts as a co-factor at enhancers occupied by AP1 transcription factors acting downstream of the MEK/ERK pathway. Consistently, loss of ARID1A led to a disruption of KRAS/AP1-dependent enhancer activity, accompanied by a downregulation of expression of the associated target genes. CONCLUSIONS: We identify a previously unknown context-dependent tumor-supporting function of ARID1A in CRC downstream of KRAS signaling. Upon the loss of ARID1A in KRAS-mutated cells, enhancers that are co-occupied by ARID1A and the AP1 transcription factors become inactive, thereby leading to decreased target gene expression. Thus, targeting of the BAF complex in KRAS-mutated CRC may offer a unique, previously unknown, context-dependent therapeutic option in CRC.</p>',

<p style="text-align: justify;">CATS relies on polynucleotide tailing for capturing the 3’-ends of nucleic acids and the template switching ability of MMLV-RT to capture the 5’ ends for cDNA synthesis. This kit allows for generating Illumina compatible ready-to-sequence libraries from <strong>RNA inputs as low as 100 picograms</strong> of polyA selected material in just few hours.</p>
<p style="text-align: justify;">Libraries retain <strong>strand specificity</strong> of origin. Unlike competing solutions, our CATS RNA-seq kit exhibits <strong>higher library efficiency</strong> versus ligation-based methods providing <strong>higher complexity</strong> from better template capture and minimal bias due to <strong>lower amplification</strong> requirements.</p>

'description' => '<p>BACKGROUND: ARID1A (AT-rich interactive domain-containing protein 1A) is a subunit of the BAF chromatin remodeling complex and plays roles in transcriptional regulation and DNA damage response. Mutations in ARID1A that lead to inactivation or loss of expression are frequent and widespread across many cancer types including colorectal cancer (CRC). A tumor suppressor role of ARID1A has been established in a number of tumor types including CRC where the genetic inactivation of Arid1a alone led to the formation of invasive colorectal adenocarcinomas in mice. Mechanistically, ARID1A has been described to largely function through the regulation of enhancer activity. METHODS: To mimic ARID1A-deficient colorectal cancer, we used CRISPR/Cas9-mediated gene editing to inactivate the ARID1A gene in established colorectal cancer cell lines. We integrated gene expression analyses with genome-wide ARID1A occupancy and epigenomic mapping data to decipher ARID1A-dependent transcriptional regulatory mechanisms. RESULTS: Interestingly, we found that CRC cell lines harboring KRAS mutations are critically dependent on ARID1A function. In the absence of ARID1A, proliferation of these cell lines is severely impaired, suggesting an essential role for ARID1A in this context. Mechanistically, we showed that ARID1A acts as a co-factor at enhancers occupied by AP1 transcription factors acting downstream of the MEK/ERK pathway. Consistently, loss of ARID1A led to a disruption of KRAS/AP1-dependent enhancer activity, accompanied by a downregulation of expression of the associated target genes. CONCLUSIONS: We identify a previously unknown context-dependent tumor-supporting function of ARID1A in CRC downstream of KRAS signaling. Upon the loss of ARID1A in KRAS-mutated cells, enhancers that are co-occupied by ARID1A and the AP1 transcription factors become inactive, thereby leading to decreased target gene expression. Thus, targeting of the BAF complex in KRAS-mutated CRC may offer a unique, previously unknown, context-dependent therapeutic option in CRC.</p>',

<p style="text-align: justify;">CATS relies on polynucleotide tailing for capturing the 3’-ends of nucleic acids and the template switching ability of MMLV-RT to capture the 5’ ends for cDNA synthesis. This kit allows for generating Illumina compatible ready-to-sequence libraries from <strong>RNA inputs as low as 100 picograms</strong> of polyA selected material in just few hours.</p>

<p style="text-align: justify;">CATS relies on polynucleotide tailing for capturing the 3’-ends of nucleic acids and the template switching ability of MMLV-RT to capture the 5’ ends for cDNA synthesis. This kit allows for generating Illumina compatible ready-to-sequence libraries from <strong>RNA inputs as low as 100 picograms</strong> of polyA selected material in just few hours.</p>
<p style="text-align: justify;">Libraries retain <strong>strand specificity</strong> of origin. Unlike competing solutions, our CATS RNA-seq kit exhibits <strong>higher library efficiency</strong> versus ligation-based methods providing <strong>higher complexity</strong> from better template capture and minimal bias due to <strong>lower amplification</strong> requirements.</p>

<p>The D-Plex mRNA-seq Library Preparation Kit is a tool designed for gene expression analysis. <span>The kit utilizes the</span><a href="https://www.diagenode.com/en/pages/dplex" target="_blank"><span> </span>D-Plex technology</a><span><span> </span>to generate directional libraries for Illumina sequencing directly from total RNAs.</span></p>
<p><span>The D-Plex technology utilizes two innovative ligation-free mechanisms - poly(A) tailing and template switching - to produce sequencing libraries from low input samples, down to 10 ng of total RNAs. Combined with unique molecular identifiers (UMI), this complete solution delivers a high-sensitivity detection method for gene expression analysis and discovery applications in the coding transcriptome.</span></p>
<p><span></span><span>The D-Plex mRNA-seq Kit offers a time-saving protocol that can be completed within 6 hours and requires minimal hands-on time. <span>The library preparation takes place in a </span><span>single tube</span><span>, increasing the efficiency tremendously. This new solution has been developped to capture an increased number of genes for great discovery efficiency.</span></span></p>
<p><span><span>The D-Plex mRNA-seq Kit includes all buffers and enzymes necessary for mRNA capture and library preparation. Specific D-Plex Unique Dual Indexes were designed and validated to fit the D-Plex technology and are available separately:</span></span></p>

'description' => '<p>: There is no standard chemotherapy for refractory or relapsing malignant pleural mesothelioma (MPM). Our previous reports nevertheless indicated that a combination of an anthracycline (doxorubicin) and a lysine deacetylase inhibitor (valproic acid, VPA) synergize to induce the apoptosis of MPM cells and reduce tumor growth in mouse models. A Phase I/II clinical trial indicated that this regimen is a promising therapeutic option for a proportion of MPM patients. : The transcriptomes of mesothelioma cells were compared after Illumina HiSeq 4000 sequencing. The expression of differentially expressed genes was inhibited by RNA interference. Apoptosis was determined by cell cycle analysis and Annexin V/7-AAD labeling. Protein expression was assessed by immunoblotting. Preclinical efficacy was evaluated in BALB/c and NOD-SCID mice. : To understand the mechanisms involved in chemoresistance, the transcriptomes of two MPM cell lines displaying different responses to VPA-doxorubicin were compared. Among the differentially expressed genes, transforming growth factor alpha (TGFα) was associated with resistance to this regimen. The silencing of TGFα by RNA interference correlated with a significant increase in apoptosis, whereas the overexpression of TGFα desensitized MPM cells to the apoptosis induced by VPA and doxorubicin. The multi-targeted inhibition of histone deacetylase (HDAC), HER2 and TGFα receptor (epidermal growth factor receptor/EGFR) improved treatment efficacy in vitro and reduced tumor growth in two MPM mouse models. Finally, TGFα expression but not EGFR correlated with patient survival. : Our data show that TGFα but not its receptor EGFR is a key factor in resistance to MPM chemotherapy. This observation may contribute to casting light on the promising but still controversial role of EGFR signaling in MPM therapy.</p>',

'description' => '<p>BACKGROUND: ARID1A (AT-rich interactive domain-containing protein 1A) is a subunit of the BAF chromatin remodeling complex and plays roles in transcriptional regulation and DNA damage response. Mutations in ARID1A that lead to inactivation or loss of expression are frequent and widespread across many cancer types including colorectal cancer (CRC). A tumor suppressor role of ARID1A has been established in a number of tumor types including CRC where the genetic inactivation of Arid1a alone led to the formation of invasive colorectal adenocarcinomas in mice. Mechanistically, ARID1A has been described to largely function through the regulation of enhancer activity. METHODS: To mimic ARID1A-deficient colorectal cancer, we used CRISPR/Cas9-mediated gene editing to inactivate the ARID1A gene in established colorectal cancer cell lines. We integrated gene expression analyses with genome-wide ARID1A occupancy and epigenomic mapping data to decipher ARID1A-dependent transcriptional regulatory mechanisms. RESULTS: Interestingly, we found that CRC cell lines harboring KRAS mutations are critically dependent on ARID1A function. In the absence of ARID1A, proliferation of these cell lines is severely impaired, suggesting an essential role for ARID1A in this context. Mechanistically, we showed that ARID1A acts as a co-factor at enhancers occupied by AP1 transcription factors acting downstream of the MEK/ERK pathway. Consistently, loss of ARID1A led to a disruption of KRAS/AP1-dependent enhancer activity, accompanied by a downregulation of expression of the associated target genes. CONCLUSIONS: We identify a previously unknown context-dependent tumor-supporting function of ARID1A in CRC downstream of KRAS signaling. Upon the loss of ARID1A in KRAS-mutated cells, enhancers that are co-occupied by ARID1A and the AP1 transcription factors become inactive, thereby leading to decreased target gene expression. Thus, targeting of the BAF complex in KRAS-mutated CRC may offer a unique, previously unknown, context-dependent therapeutic option in CRC.</p>',

<ul>
<li>Diverse transcripts detection</li>
<li>Excellent reproducibility with ultra low inputs down to 100 pg</li>
<li>Great performance on challenging samples</li>

<div id="more" class="content">
<p style="text-align: justify;">CATS relies on polynucleotide tailing for capturing the 3’-ends of nucleic acids and the template switching ability of MMLV-RT to capture the 5’ ends for cDNA synthesis. This kit allows for generating Illumina compatible ready-to-sequence libraries from <strong>RNA inputs as low as 100 picograms</strong> of polyA selected material in just few hours.</p>
<p style="text-align: justify;">Libraries retain <strong>strand specificity</strong> of origin. Unlike competing solutions, our CATS RNA-seq kit exhibits <strong>higher library efficiency</strong> versus ligation-based methods providing <strong>higher complexity</strong> from better template capture and minimal bias due to <strong>lower amplification</strong> requirements.</p>

'description' => '<p>BACKGROUND: ARID1A (AT-rich interactive domain-containing protein 1A) is a subunit of the BAF chromatin remodeling complex and plays roles in transcriptional regulation and DNA damage response. Mutations in ARID1A that lead to inactivation or loss of expression are frequent and widespread across many cancer types including colorectal cancer (CRC). A tumor suppressor role of ARID1A has been established in a number of tumor types including CRC where the genetic inactivation of Arid1a alone led to the formation of invasive colorectal adenocarcinomas in mice. Mechanistically, ARID1A has been described to largely function through the regulation of enhancer activity. METHODS: To mimic ARID1A-deficient colorectal cancer, we used CRISPR/Cas9-mediated gene editing to inactivate the ARID1A gene in established colorectal cancer cell lines. We integrated gene expression analyses with genome-wide ARID1A occupancy and epigenomic mapping data to decipher ARID1A-dependent transcriptional regulatory mechanisms. RESULTS: Interestingly, we found that CRC cell lines harboring KRAS mutations are critically dependent on ARID1A function. In the absence of ARID1A, proliferation of these cell lines is severely impaired, suggesting an essential role for ARID1A in this context. Mechanistically, we showed that ARID1A acts as a co-factor at enhancers occupied by AP1 transcription factors acting downstream of the MEK/ERK pathway. Consistently, loss of ARID1A led to a disruption of KRAS/AP1-dependent enhancer activity, accompanied by a downregulation of expression of the associated target genes. CONCLUSIONS: We identify a previously unknown context-dependent tumor-supporting function of ARID1A in CRC downstream of KRAS signaling. Upon the loss of ARID1A in KRAS-mutated cells, enhancers that are co-occupied by ARID1A and the AP1 transcription factors become inactive, thereby leading to decreased target gene expression. Thus, targeting of the BAF complex in KRAS-mutated CRC may offer a unique, previously unknown, context-dependent therapeutic option in CRC.</p>',
