Project description:This SuperSeries is composed of the following subset Series: GSE25210: Genome-wide mapping of Flag-Evi1 in SKOV-3 ovarian carcinoma cells GSE25212: Effects of Evi1 knockdown and overexpression in SKOV-3 ovarian carcinoma cells GSE33724: Effects of EVI1 mild expression in HeLa cells Refer to individual Series
Project description:We studied the variations of mRNA amounts after Evi1 knockdown or Flag-Evi1 overexpression in SKOV-3 cells. Despites Evi1 discovery in 1988, its recognized role as a dominant oncogene in myeloid leukemia and more recently in epithelial cancers, only a few target genes were known and it was not clear why Evi1 was involved in cancer progression. Here we obtained the genomic binding occupancy and expression data for Evi1 in human ovarian carcinoma cells. We identified numerous Evi1 target cancer genes and genes controlling cell migration and adhesion. Moreover, we characterized a transcriptional cooperation between AP1 and Evi1 that regulated proliferation and adhesion through a feed-forward loop. Furthermore, this study provides human genome-wide mapping and downstream analyses for Evi1 that will be useful for the research community. 16 samples were collected. Each condition was done in 4 replicates, collected 65 hours after transfection. Transfections with control siRNA or Flag-expressing vector were used as controls.

Project description:The purpose of this experiment was to identify the effects of ATP depletion (using apyrase) on a metastatic ovarian carcinoma cell line (SKOV-3) and compare it to a non-treated sample. Cells were treated either with media alone or with media with apyrase during 24h. SKOV-3 cells were harvested during 12h prior to incubation. RNA was extracted with TRIZOL reagent and 10ug of RNA were used to synthetize cDNA
