Project description:We studied the variations of mRNA amounts after Flag-EVI1, Flag-EVI1?324, or Flag expression in HeLa 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 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. This study provides human genome-wide mapping and expression analyses for EVI1 that will be useful for the research community. 12 samples were collected. Each condition was done in 4 replicates, collected 24 hours after transfection (for mild expression of EVI1 or EVI1?324). Transfections with Flag-expressing vector were used as controls.

Furthermore, this study provides human genome-wide mapping and downstream analyses for EVI1 that will be useful for the research community. 8 samples were collected. Each condition was done in 4 replicates, collected 24 hours after transfection (for mild expression of EVI1). Transfections with Flag-expressing vector were used as controls.

Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
