Estradiol and its nuclear receptors, estrogen receptor (ER) alpha and ERbeta, play critical roles in endometrium and endometriosis. Levels of ERbeta, due to pathological hypomethylation of its promoter, are significantly higher in endometriotic vs. endometrial tissue and stromal cells, whereas ERalpha levels are lower in endometriosis. Estradiol regulates ERalpha gene expression via its alternatively used promoters A, B, and C.
