摘要:: Chromatin immunoprecipitation (ChIP) technique allows detection of proteins that bind to chromatin. While this technique has been applied extensively in cell-based studies, its tissue-based application remains poorly explored. We are specifically interested in examining estrogen-dependent transcriptional mechanism in respect of recruitment of estrogen receptor-alpha (ERalpha), a ligand-activated transcription factor, to uterine gene promoters in mice. Recent gene-array studies, utilizing ERalpha knock-out vs. wild-type mice, have revealed that estrogen regulates numerous uterine genes temporally and most importantly via ERalpha during the phase-II response, including three well characterized genes viz., lactoferrin (Ltf), progesterone receptor (Pgr) and cyclinD1 (Ccnd1). Here, utilizing systematic ChIP studies, we demonstrate endogenous recruitment of ERalpha to above uterine gene promoters following estradiol-17beta (E(2)) injection in mice.
