Response to estradiol-ERalpha. Homo sapiens

In addition to the estrogen responsive element (ERE)-dependent gene expression, E2-ERalpha regulates transcription through functional interactions with transfactors bound to their cognate regulatory elements on DNA, hence the ERE-independent signaling pathway. However, the relative importance of the ERE-independent pathway in E2-ERalpha signaling is unclear. Our studies in infected ER-negative cell models with an ERalpha demonstrated that genomic responses assessed by microarrays from the alter cellular growth, death or motility. Keywords: MDA-MB-231 cells Overall design: Cells were infected with the recombinant adenovirus bearing no cDNA (CMV) or cDNA for ERalpha for 48h. Infected cells were then treated with 1 nM Estradiol 17beta for 6h. All experiments were repeated six independent times conducted at at six different days
