CONTEXT: Recent evidence implicates the orphan nuclear receptor, nuclear receptor subfamily 2, group F, member 2 (NR2F2; chicken ovalbumin upstream promoter-transcription factor II) as both a master regulator of angiogenesis and an oncogene…

CONTEXT: Endometriosis is a common gynecologic condition characterized by an important inflammatory process mediated by the prostaglandin pathway. Oral contraceptives are the treatment of choice for symptomatic endometriotic women. However …

CONTEXT: Endometriosis is characterized by progesterone resistance and hyperactivity of the AKT and MAPK pathways. Kinases can cause posttranslational modifications of the progesterone receptor (PR) to influence cellular localization and pr…

CONTEXT: Endometriosis is characterized by the growth of ectopic endometrial tissue. Nerve fibers are frequently associated with ectopic lesions, and neurogenic inflammation may play a role in endometriosis. OBJECTIVE: The purpose of this …

CONTEXT: Endometriosis affects 10% of the women before menopause and has important personal, professional, and societal economic burdens. Because current medical treatments are aimed at reducing the symptoms only, novel therapeutic targets …

CONTEXT: Endometriosis is a chronic inflammatory disease in which immune response and production of estrogen in endometriotic tissues are involved in the development of the disease. Prostaglandin E2 (PGE2) stimulates aromatase (P450arom) ex…

CONTEXT: Endometrium in polycystic ovary syndrome (PCOS) presents altered gene expression indicating progesterone resistance and predisposing to reduced endometrial receptivity and endometrial cancer. OBJECTIVE: We hypothesized that an alt…

CONTEXT: Steroidogenic factor (SF)-1 and its downstream target genes involved in estrogen signaling are aberrantly expressed in ovarian endometriosis. OBJECTIVE: Our objective was to explore the microRNA-mediated mechanism controlling aber…

BACKGROUND: Homeobox A10 (HOXA10), a key transcription factor, plays a critical role in endometrial receptivity by regulating the expression of downstream target genes, such as β3-integrin (ITGB3), but little is understood about the mechani…

CONTEXT: Endometriosis is a common gynecological condition characterized by enhanced proliferation, adhesiveness, invasiveness, and survival of endometrial cells after retrograde menstruation. Originally identified as a cytoskeletal regulat…

CONTEXT: Polyunsaturated fatty acids (PUFAs) and their metabolism may be important in normal reproductive function and fertility. Associations between physiologic PUFAs and pregnancy have not been established in women. OBJECTIVE: The purpo…

CONTEXT: Growth of endometriotic lesions in rodent model of endometriosis is inhibited by resveratrol, a natural polyphenol with antiproliferative and antiinflammatory properties, and simvastatin, an inhibitor of 3-hydroxy-3-methylglutaryl-…

CONTEXT: Premenopausal women with idiopathic osteoporosis (IOP) have abnormal cortical and trabecular bone microarchitecture. OBJECTIVE: The purpose of this study was to test the hypotheses that teriparatide increases bone mineral density …

CONTEXT: Anti-mullerian hormone (AMH) has emerged as a marker of ovarian reserve and a possible surrogate measure of reproductive aging. OBJECTIVE: The aim of the study was to evaluate the predictive value of AMH levels in determining the …

CONTEXT: There is currently no reliable noninvasive biomarker for the clinical diagnosis of endometriosis. Previous analyses have reported that circulating microRNAs (miRNAs) can serve as biomarkers for a number of diseases. OBJECTIVE: The…

BACKGROUND: During pregnancy, uteroplacental responses to norepinephrine (NE) exceed systemic responses. In contrast, uteroplacental responses to angiotensin II (ANG II) are less than systemic. The explanation for these differences in utero…

CONTEXT: Aberrant estrogen synthesis and metabolism have been suggested to increase local estradiol (E2) concentration in endometriosis and thus to promote the growth of the lesions. However, tissue estrogen concentrations within the endome…

CONTEXT: Evidence suggests that a number of microRNA (miRNA) are aberrantly expressed in endometrial disorders with potential posttranscriptional regulation of their specific target genes, including ovarian steroid receptors. OBJECTIVES: O…

CONTEXT: Aberrant activation of MAPK has been implicated to play important roles in pathological processes of endometriosis. However, how MAPK are constitutively activated in endometriotic tissues remains largely unknown. microRNA are small…

CONTEXT: Endometriosis is characterized by progesterone resistance and associated with infertility. Krüppel-like factor 9 (KLF9) is a progesterone receptor (PGR)-interacting protein, and mice null for Klf9 are subfertile. Whether loss of KL…

CONTEXT: A high chromosomal abnormalities rate has been observed in human embryos derived from in vitro fertilization (IVF) treatments. The real incidence in natural cycles has been poorly studied, so whether this frequency may be induced b…

CONTEXT: Müllerian inhibiting substance (MIS) is produced in Sertoli cells of fetal testis and causes regression of müllerian ducts in male embryos. MIS also can induce the cell cycle arrest and apoptosis in müllerian duct-derived tumors in…

CONTEXT: Uterine remodeling is highly dependent on the glycosylated transmembrane protein extracellular matrix metalloproteinase (MMP) inducer (EMMPRIN). Previous studies indicate estradiol can increase EMMPRIN expression in uterine cells a…

CONTEXT: Endometriomas are mainly treated surgically. However, there has been concern over the potential damaging effect of this surgery on ovarian reserve. OBJECTIVE: The aim of this meta-analysis was to investigate the impact of surgery …

CONTEXT: Menstruation is preceded by progesterone withdrawal and endometrial matrix remodeling predominantly through induction of matrix metalloproteinases (MMP) and recruitment of invading neutrophils. DESIGN: Using endometrial tissues fr…
