    ABSTRACT: To determine FOXO1 (forkhead box O1) expression in the human endometrium during the menstrual cycle and decidua of early pregnancy, as well as FOXO1 regulation in endometrial stromal cells (ESC). Immunohistochemistry, RT-qPCR, and Western blot analyses evaluated cellular localization and altered FOXO1 expression in the endometrium during the menstrual cycle and decidua of early pregnancy (proliferative phase, n = 12; early-secretory phase, n = 7; mid-secretory phase, n = 10; late-secretory phase, n = 10; early pregnancy, n = 12). Using RT-qPCR and Western blot, we studied the regulation of FOXO1 by 8-bromo-cAMP, 4-pregnene-3,20-dione, 17β-estradiol, and human chorionic gonadotrophin in ESC (n = 5). The expression level of FOXO1 in human endometrial tissue fluctuated with the menstrual cycle. If pregnancy occurred, the expression of FOXO1 was further increased (p < 0.05) and cAMP regulated FOXO1 expression in ESC. In addition, 4-pregnene-3,20-dione cooperatively stimulated FOXO1 expression with cAMP. We also observed FOXO1 expression during in vitro cAMP-induced decidualization. The pattern of FOXO1 expression suggests a potential role for FOXO1 in implantation and decidualization.
