Expression data from pancreatic cancer cell line MiaPaca2 [control]

ABSTRACT: tumor-stroma crosstalk drives pancreatic carcinogenesis we used time-resolved genome-wide transcriptional profiling to analyse changes caused by co-exposure of pancreatic tumor and stellate cells pancreatic tumor cell line MiaPaca2 was treated with a supernatant of pancreatic stellate cells and harvested hourly at 1-7, and 24 hours post exposure for RNA extraction and hybridization on Affymetrix microarrays.

Expression data from pancreatic stellate cells

Project description:tumor-stroma crosstalk drives pancreatic carcinogenesis we used time-resolved genome-wide transcriptional profiling to analyse changes caused by co-exposure of pancreatic tumor and stellate cells Primary pancreatic Stellate cells (PSC) were treated with a cumulative supernatant of pancreatic tumor cell lines (n=8) and harvested at 1-7, and 24 hours post exposure for RNA extraction and hybridization on Affymetrix microarrays. The 8 tumor cell lines are pancreatic ductal adenocarcinoma lines: AsPC1, BxPC3, Capan1, Colo357, MiaPaca2, Panc1, Su8686, and T3M4

Genes regulated by AGR2 in pancreatic cancer cell lines FA6 and MiaPaCa2

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.

Genome wide analysis of pancreatic cancer cell gene expresison exposed to stromal pancreatic stellate cells in 3D gel matrix

Project description:Capan1 (well differentiated pancreatic cancer cell line) was co-cultured with pancreatic stellate cell line (PS1) embedded in a 3D organotypic model and gene expression was analysed in comparison to cancer cells cultured alone without stellate cells. Pancreatic stellate cells were embedded within a gel matrix composing collagen type I and Matrigel, and cancer cells were seeded on top. The gel was lifted on to metal grid after 24 hour and fed from below. Gels were harvested on day 10 and frozen sections obtained. The cancer cell layer on top of the gel was captured by laser microdissection for RNA extraction.

Transcriptional profiling comparing MiaPaCa2 pancreatic cancer cells transfected with S100PBP siRNA to MiaPaCa2 cells transfected with non-targeting control siRNA

Project description:S100PBP is significantly down-regulated in pancreatic cancer compared to normal samples. The functional roles of S100PBP are unknown, and therefore, profiling cells after silencing of this gene may lead to further understanding of its functional mechanisms. We have performed microarray gene expression analysis of MiaPaCa2 cells treated with S100PBP siRNA compared to the same cells transfected with non-targeting control siRNA.

Deactivation of Hepatic Stellate Cells during Liver Fibrosis Resolution in Mice

Project description:Gene expression of mouse hepatic stellate cells was characterized under the following conditions: Quiescent (isolated from normal mouse liver) and reverted (isolated from mouse liver treated with 4 injections of carbontetrachloride followed by 45 day rest period) Affymetrix Mouse 1.0ST gene expression measurements were used to characterize the transcriptomic basis in quiescent hepatic stellate cells, isolated from normal liver, and reverted hepatic stellate cells, isolated from liver treated with 4 injections of CCl4 followed by a 45 day rest period. Gene expression of mouse hepatic stellate cells was characterized under the following conditions: A. Quiescent control hepatic stellate cells (n=4). B. Reverted hepatic stellate cells (n=4).
