THE ESTROGEN RECEPTOR Α CISTROME IN HUMAN ENDOMETRIUM AND EPITHELIAL ORGANOIDS
Women aged 19 to 34 years old, with regular intermenstrual interval between 25 and 35 days, and no history of infertility or pelvic disease were included in the study. Endometrial biopsies were collected and processed for ESR1 ChIPseq and isolation of epithelial cells for culture of organoids. Study findings include a preferential enrichment of HOX motifs in the mid-secretory ESR1 peaks, and bHLH motifs are enriched in proliferative and mid-secretory ESR1 peaks. Data presented in this study elucidates details of estrogen-mediated response in uterine tissue.
