Cell fate specification is a critical process to generate cells with a wide range of characteristics from stem and progenitor cells. Emerging evidence demonstrates that the orphan nuclear receptor COUP-TFII serves as a key regulator in dete…

Epigenetic silencing of steroidogenic factor 1 (SF1) is lost in endometriosis, potentially contributing to de novo local steroidogenesis favoring inflammation and growth of ectopic endometrial tissue. In this study, we examine the impact of…

Alterations in estrogen-mediated cellular signaling play an essential role in the pathogenesis of endometriosis. In addition to higher estrogen receptor (ER) β levels, enhanced ERβ activity was detected in endometriotic tissues, and the inh…

As pleiotropic coregulators, members of the p160/steroid receptor coactivator (SRC) family control a broad spectrum of transcriptional responses that underpin a diverse array of physiological and pathophysiological processes. Because of the…

CONTEXT: Endometriosis is one of the most common gynecological diseases in women with a prevalence rate of approximately 10%. Chronic pelvic inflammation has been observed in patients with endometriosis and is associated with disease severi…

Chicken ovalbumin upstream promoter-transcription factor II (COUP-TFII; NR2F2) is an orphan nuclear receptor involved in cell-fate specification, organogenesis, angiogenesis, and metabolism. Ablation of COUP-TFII in the mouse uterus causes …

COUP-TFII is an orphan nuclear receptor of the nuclear receptor superfamily. COUP-TFII is highly expressed in the uterine stroma and its expression is controlled by progesterone-Ihh-Ptch signaling from the epithelium to the stroma. Mutants …

Healthy uterine function depends on the balanced interaction of the ovarian steroids estrogen and progesterone (P4) signaling through their respective receptors. The expression of each receptor is regulated by the other through crucial cros…

Normal endometrial function requires a balance of progesterone (P4) and estrogen (E2) effects. An imbalance caused by increased E2 action and/or decreased P4 action can result in abnormal endometrial proliferation and, ultimately, endometri…

In order for a successful pregnancy to occur, the embryo must attach to the luminal epithelial cells and invade into the stroma. Then, the surrounding stromal cells need to undergo decidualization in order to establish the vasculature neces…

Progesterone and estrogen are critical regulators of uterine receptivity. To facilitate uterine remodeling for embryo attachment, estrogen activity in the uterine epithelia is attenuated by progesterone; however, the molecular mechanism by …
