Project description:Recent studies suggest that PDEF is required for secretory cell differentiation in several epithelial tissues. To investigate PDEF in the mammary gland, we examined the effect of this transcription factor on gene expression using microarray based profiling of MCF-10A cells. These cells are non-transformed mammary epithelial cells that express protein and gene expression programs of basal epithelial cells and undetectable levels of endogenous PDEF. Bioinformatics analysis of the genes induced or repressed by PDEF overexpression in MCF10A cells revealed a striking effect on expression of luminal and myoepithelial cell markers.

Bioinformatics analysis of the genes induced or repressed by PDEF overexpression in MCF10A cells revealed a striking effect on expression of luminal and myoepithelial cell markers. Six samples were harvested 26 hours after retroviral infection with either vector control or PDEF. Each condition was performed in triplicate.
Project description:Genome wide DNA methylation profiling of human mammary epithelial MCF10A cell line treated with vehicle control (ethanol) and with RSV (resveratrol). The Illumina Infinium 450K Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 450,000 CpGs in human cell lines exposed to described treatments. Samples included biological triplicate of MCF10A control (ethanol treated), biological triplicate of MCF10A treated with RSV.
Project description:RNA-seq was performed for transcriptional analysis of MCF10A cells, an epithelial mammary cell line. MCF10A cells were cultured in 3D acinus forming conditions (in Matrigel). Timepoints analysed were 24h, 34h, 36h, 38h and 48h into acinus formation. Control cells were monoloayer.
