RNA-Seq comparisons of gene expression profiles of epithelial and mesenchymal cells - HMLE, N8, N8-CTx

We find that treating mesenchymal NAMEC8 cells with cholera toxin (CTx) to elevate intracellular cAMP levels and activate PKA induces a mesenchymal-to-epithelial transition whereby the cells assume an epithelial state (N8-CTx). NAMEC8 cells undergo epigenetic reprogramming triggered by active PHF2, a histone demethylase, which demethylates H3K9me2 and H3K9me3 regions of epithelial genes silencing in the mesenchymal state Overall design: Performing RNASeq with HMLE (immortalized human mammary epithelial cells), their mesenchymal CD44hi counterparts, NAMEC8 and the CTx-reverted versions of NAMEC8 a.k.a N8-CTx
