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.

Project description:We and others have shown that AGR2 is frequently upregulated during the development of pancreatic cancer. We used microarray to look at the target genes regulated by AGR2 in pancreatic cancer cell lines FA6 and MiaPaCa2. Keywords: gene knock-down, overexpression We transiently down-regulated AGR2 expression in FA6 pancreatic cancer cells using INTERFERin transfection reagent and either AGR2 siRNA or non-targeting control siRNA for 48 hours. RNA was extracted and hybridized on Affymetrix microarrays. We looked for new target genes regulated by AGR2. We generated stable cell lines by introducing control vector pCEP4 or AGR2 overexpressing vector pCEP4-AGR2 into the pancreatic cancer cell line MiaPaCa2, single cell clones were then isolated. RNA was extracted and hybridized on Affymetrix microarrays.We looked for new target genes regulated by AGR2.

Project description:We and others have shown that S100P is highly upregulated during the progression of pancreatic cancer. We used microarrays to look at the target genes regulated by S100P in the pancreatic cancer cell line Panc1. Keywords: Gene overexpression We generated stable cell lines by introducing control vector pcDNA3.1/V5-His or S100P-overexpressing vector pcDNA3.1/S100P-V5-His into the pancreatic cancer cell line Panc1, single cell clones were then isolated. RNA was extracted and hybridized on Affymetrix microarrays. We looked for new target genes regulated by S100P.

Project description:Transcriptional deregulation of oncogenic pathways is a hallmark of cancer, and can be due to epigenetic alterations. 5-hydroxymethylcytosine is a recently discovered epigenetic modification that has not been studied in pancreatic cancer. Genome-wide analysis of 5-hmC enriched loci was conducted in low-passage pancreatic cancer cell lines and primary patient-derived xenografts and revealed strikingly altered patterns in neoplastic tissues. Differentially hydroxymethylated regions preferentially affected regulatory regions of the genome, specifically overlapping with H3K4me1 enhancers. Gain of 5-hmC was correlated with upregulation of the cognate transcripts, including many oncogenic pathways implicated in pancreatic neoplasia. Specifically, BRD4 was overexpressed and acquired 5hmC at enhancer regions in majority of neoplastic samples. Functionally, acquisition of 5hmC at BRD4 promoter regulated increase in transcript expression. Furthermore, blockade of BRD4 inhibited pancreatic cancer growth in vivo. In summary, redistribution of 5-hmC and preferential enrichment at oncogenic enhancers is a novel regulatory mechanism in human cancer. Genome-wide analysis of 5-hmC enriched loci was conducted in low-passage pancreatic cancer cell lines and primary patient-derived xenografts
