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:Our study has shown that ARHGEF10 is a putative tumor suppressor in pancreatic ductal adenocarcinoma. To determine its functional mechanism, we perfomed microarray gene expression analysis of two pancreatic cancer cell line models of ARHGEF10 expression : MiaPACA2 cells in which ARHGEF10 was stably overexpressed, and Hs766T cells in which ARHGEF10 expression had been stably knocked down by short hairpin RNAs.
Project description:Gene profiles from three dasatinib-resistant and three dasatinib-sensitive pancreatic cancer cell lines were compared by microarray analysis. RNA from three dasatinib-resistant (MiaPaCa2, Panc1, SU8686) and three dasatinib-sensitive (Panc0504, Panc0403, Panc1005) pancreatic cancer cell lines were extracted. Biological triplicates were employed for each cell line. Complementary DNA microarray analysis was performed using Illumina Human HT-12 v4 BeadChip (Illumina, San Diego, CA) at the National University of Singapore Core Facility following the manufacturer’s instructions.
