Uterine epithelial cell estrogen receptor alpha-dependent and -independent genomic profiles that underlie estrogen responses in mice.

ABSTRACT: Estrogens exert their activity through estrogen receptor alpha (ERalpha) to stimulate hypertrophy and hyperplasia in the uterus. A uterine epithelial ERalpha conditional knockout mouse model (Wnt7a(Cre+);Esr1(f/f) or cKO) demonstrated that ERalpha in the epithelial cells was dispensable for an initial uterine proliferative response to 17beta-estradiol (E2) but required for subsequent uterine biological responses. This study aimed to characterize the differential gene expression patterns induced by E2 in the presence or absence of epithelial ERalpha. RNA microarray analysis revealed that approximately 20% of the genes differentially expressed at 2 h were epithelial ERalpha independent, as they were preserved in the cKO uteri. This indicates that early uterine transcripts mediated by stromal
