Project description:ETS2 is a canonical transcriptional factor and member of the ETS family of genes. ETS2 binds to consensus ERE binding sites in a broad spectrum of genes thus affecting many intracellular molecular functions. However, the role of ETS2 in the biology and pathogenesis of lung cancers is still not known. We have found that ETS2 is down-regulated in lung tumors compared to normal lung tissue and the expression of the coding protein of the gene was a significant independent predictor of favorable outcome in NSCLC patients pinpointing to a potential tumor suppressor role for this gene. To better understand its molecular function in NSCLC, we compared and contrasted the transcriptome of lung cancer cells transfected with control siRNA and siRNA targeting ETS2. H441 lung cancer cells were transfected with SMARTpool (Dharmacon)control/scrambled siRNA or siRNA targeting ETS2. Three independent transfections were performed cells with control siRNA and for cells with siRNA specific to ETS2 where each transfection consittutes a biological replicate. Knock-down of ETS2 in all samples was confirmed by quantitative real-time PCR. Total RNA was then profiled using the Human Gene

Project description:Gene expression data were collected by RNA-seq from HCT-116 cells in the presence or absence of siRNA targeting APC and 1,376 transcripts changed in expression following APC silencing were identified relative to scrambled siRNA-transfected and untreated controls.
Project description:Transcriptional profiling of two human lung cancer cell lines, DMS-273 (small cell lung cancer) and NCI-H1437 (non-small cell lung cancer), stably transfected either with innocuous scrambled shRNAs or SETDB1-specific.The objective was to identify global gene expression changes due to the depletion of the H3K9me3 methyltransferase SETDB1.
Project description:Transcriptional profiling for global characterization of gene expression alterations that resulted from treatment of melanoma cells with siRNA specifically targeting NRASQ61R Experiment Overall Design: BL or 224 cells transfected with siRNA against either mutant NRASQ61R (siMut10 and siMut12) or scrambled control (siSC). Untransfected cells (T0) from Day 0 were used as the baseline control for cells transfected with both siMut and siSC
Project description:Transcriptional profiling comparing MiaPaCa2 pancreatic cancer cells transfected with S100PBP siRNA to MiaPaCa2 cells transfected with non-targeting control siRNA
Project description:This study is to identify downstream targets of homeobox gene CDX1. The study assayed the expression of 2 pairs of stably transfected colorectal cancer cell lines: The CDX1 nonexpressing CRC cell line HCT116 was stably transfected with either CDX1 cDNA in the pRC/CMV expression vector (HCT116-CDX1) or with vector control (HCT116-Vec). The CDX1-expressing CRC cell line LS174T was similarly transfected with either a pSilencer vector containing a short sequence of CDX1 siRNA (LS174T-siRNA) , or a pSilencer vector containing a scrambled siRNA sequence as a control (LS174T-Vec).
