Project description:To explore micro RNAs containing methyated adenine in 4 pancreatic cancer cell lines, we tried to immunoprecipitation using anti-m6A antibdy. Imunoprecipitatted microRNA were isolated using isolated using Hipure microRNA isolation kit and sequenced. This data showed that some microRNAs had methylated adenin in pancreatic cancer cell lines.
Project description:Pancreatic ductal adenocarcinoma (PDAC) is a highly invasive cancer with a poor prognosis. Using methylated DNA immunoprecipitation (MeDIP)-chip analysis, we found that 161 genes that were specifically hypermethylated in PANC-1 cells. Among them, miR-615-5p was hypermethylated in its putative promoter region, which silenced its expression in PDAC cell lines. Comparison between PANC-1 cell lines and normal pancreas tissue

Project description:As a classic tumor suppressor pathway, Hippo signaling axis is activated by various extra-pathway factors to regulate cell differentiation and organ development. However, recent studies have reported that the activation of Hippo signaling pathway may be more dependent on the autophosphorylation of its core kinase cassette. Here, we demonstrate that protein arginine methyltransferase 5 (PRMT5) is involved in inducing the inactivation of Hippo signaling pathway in pancreatic cancer. Our study shows that the initiator serine/threonine kinase 3 (STK3, also known as MST2) of Hippo signaling pathway can be symmetrically di-methylated at arginine-461 (R461) and arginine-467 (R467) in the SARAH domain by PRMT5, and the methylated MST2 suppresses its autophosphorylation and kinase activity by blocking the formation of homodimer, thereby inactivating Hippo signaling pathway in pancreatic cancer. Moreover, we also discover that the specific PRMT5 inhibitor GSK3326595 re-activates the dysregulated Hippo signaling pathway
Project description:Expression data from pancreatic cancer cell lines and non-neoplastic pancreatic cell line HPDE To identify genes epigenetically silenced and regulated in pancreatic cancer
Project description:The goal of the study was to examine the transcriptional profile of pancreatic cancer cell lines and assess if the molecular subtypes observed in tumor samples were represented in existing cell line models. Cell line models allow us to investigate if the molecular subtype observed in tumor have unique sensitivity profiles to anticancer drugs. 29 pancreatic cancer cell lines were compared to a mixed reference pool of 30 pancreatic cancer cell lines to identify cell line specific gene expression.
Project description:Expression data from pancreatic cancer cell lines and non-neoplastic pancreatic cell line HPDE To identify genes epigenetically silenced and regulated in pancreatic cancer We compared the gene expression profiles of 6 pancreatic cancer cell lines (panc215, A32-1, A38-5, panc2.5, panc2.8, and panc3.014), to the non-neoplastic pancreas cell line, HPDE. We also compared the baseline gene expression of the pancreatic cancer cell lines to expression patterns after treatment with 5-aza-dC alone, TSA alone, and to a combination of 5-aza-dC/TSA.
