Expression data of TS cells with inactive MAP3K4 (TSKI4 cells) and TSKI4 cells re-expressing REL (TSKI4R cells)

Trophoblast stem cells lack MAP3K4 activity (TSKI4 cells) switch from epithelial phenotype to intermediate phenotype. Loss of epithelial phenotype is due to the loss of CBP histone acetyltransferase activity and the gain of histone deacetylase HDAC6 expression and activity. In our work, we identify a small network of 183 genes whose expression is co-regulated by MAP3K4, CBP, and HDAC6. Further, we define the key role of one of these co-regulated genes, Rel, in inducing epithelial phenotype in intermediate TSKI4 cells. We used microarrays to compare gene expression betweeen mesenchymal TS cells with inactive MAP3K4 (TSKI4 cells) and epithelial TSKI4 cells re-expressing REL (TSKI4R cells) TS cells with inactive MAP3K4 (TSKI4 cells) and TSKI4 cells re-expressing REL (TSKI4R cells) were cultured for 4 days under stemness conditions. Total RNA was extracted and hybridized on Affymetrix microarrays.
