Project description:Transcriptome analysis of EYA2 non-expressing pancreatic cancer cell lines with stable transfectant overexpressing EYA2 We analyzed Panc2.5 and Panc3.014 stable transfectant (overexpressing EYA2) and control (empty pcDNA6.2/cLumio-DEST vector) cell transcriptomes using the Affymetrix Exon Array ST1.0 platform. Statistical analysis of gene expression array data was completed with Partek Genomic Suite 6.4 software.
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:Gene expression of T47D-MTVL human breast cancer cells expressing Dox-inducible shRNAs against histone H1.4 (sh120) or multiple H1 variants (sh225), or overexpressing WT or K26A mutant HA-tagged H1.4. T47D-MTVL, breast cancer cell line carrying one stably integrated copy of luciferase reporter gene driven by the MMTV promoter, is stably infected with an inducible system for the expression of shRNAs.Cells stably express RedFP and KRAB repressor fused to Tet regulator.Upon Dox treatment, cells express RedFP and the cloned shRNA. Stable breast cancer-derived cell lines expressing an shRNA against one of each of the histone H1 isoforms in response to doxycycline (Dox) were grown for six days in the presence or absence of Dox, in duplicate, and RNA extracted for microarray hybridization. Cell lines used: inducible shRNA against H1.4 or multiple H1 variants, and random shRNA-expression vector. Stable breast cancer-derived cell lines expressing the histone H1.4 isoform, WT or K26A, HA-tagged, in duplicate, and RNA extracted for microarray hybridization. Cell lines used: overexpressing H1.4 WT or K26A mutant.
Project description:Label-free whole cell proteomics was performed for the following cell lines: LHS-PREC engineered to overexpress MYC or EV; P4936 overexpressing MYC on a tetracycline-repressible promotor; MCF10A cells expressing signal transduction oncogenes AKT, BRAF, EGFR, HER2, KRAS, MEK; KP4 and PSN1 PDAC cell lines vs HPDE normal pancreatic cell; PDX-derived osteosarcoma cell lines with MYC amplification vs hFOB cell
Project description:This SuperSeries is composed of the following subset Series: GSE40097: DNA methylation analysis of pancreatic cancer and non-malignant pancreas cell lines GSE40098: RNA expression analysis of pancreatic cancer and non-malignant pancreas cell lines GSE41794: DNA copy number profiling of 20 pancreatic cancer cell lines Refer to individual Series
Project description:Chromosomal rearrangements involving ETS factors, ERG and ETV1, occur frequently in prostate cancer. We here examine human prostate non-tumorigenic RWPE-1 cells with ERG- or ETV1-expressing stable RWPE-1 cell. RWPE-1 stable cell clones overexpressing ERG and ETV1 were grown under normal conditions. Total RNA was extracted from three biological replicates. This was used to hybridize to Affymetrix expression arrays using the HG-U133 Plus 2.0 platform.
