CONTEXT: Tissue-specific dicer1 knockout mice display severe, irreversible Fallopian tube damage and disrupted tubal transport. It is not known how Dicer1 affects human Fallopian tube function. OBJECTIVE: The aim of the study was to invest…

CONTEXT: During the development of endometriotic lesions, excess fibrosis may lead to scarring and to the alterations of tissue function that are the characteristic features of this disease. Enhanced extracellular matrix contractility of en…

BACKGROUND: Accumulating evidence suggests that aquaporins (AQP) can facilitate cell migration, invasion, and proliferation in tumor development in addition to water transport. OBJECTIVE: The aim of this study was to examine AQP2 expressio…

CONTEXT: Women with endometriosis have altered endometrial function. CRH and urocortin (Ucn) are neuropeptides produced by human endometrium and modulate endometrial decidualization. OBJECTIVE: To evaluate endometrial mRNA expression of CR…

CONTEXT: Endometriosis affects approximately 10% of women in the United States and causes pain and infertility. Decidualization of endometrial stromal cells from women with endometriosis is aberrant. OBJECTIVE: The objective of this study …

CONTEXT: The endometrium is a multicellular, steroid-responsive tissue that undergoes dynamic remodeling every menstrual cycle in preparation for implantation and, in absence of pregnancy, menstruation. Androgen receptors are present in the…

CONTEXT: Homeo box A10 (HOXA10) regulates endometrial receptivity and its expression is decreased in women with endometriosis. Although sex steroids regulate HOXA10, these hormones are unaltered in endometriosis. We hypothesized a role for …

CONTEXT: Polycystic ovary syndrome (PCOS), the most common endocrinopathy of reproductive-aged women, is characterized by ovulatory dysfunction and hyperandrogenism. OBJECTIVE: The aim was to compare gene expression between endometrial sam…

CONTEXT: The human endometrium has an exceptional capacity for repeated repair after menses, but its regulation remains undefined. Premenstrually, progesterone levels fall and prostaglandin (PG) F₂α synthesis increases, causing spiral arter…

CONTEXT: Retinoic acid (RA) controls multiple biological processes via exerting opposing effects on cell survival. Retinol uptake into cells is controlled by stimulated by RA 6 (STRA6). RA is then produced from retinol in the cytosol. Parti…

CONTEXT: A high prevalence of depressive symptoms is observed in women with primary ovarian insufficiency (POI) compared with women in whom the menopause is normally timed. Indeed, studies suggest that depression and/or its pharmacological …

CONTEXT: Only a few, small, human studies on E-cadherin and beta-catenin expression in normal cycling human endometrium have been reported. It remains unclear whether expression of these molecules might be altered in the endometrium of infe…

CONTEXT: Progesterone is critical for secretory endometrial differentiation in women, but its downstream mediators are poorly understood. OBJECTIVE: Our objective was to investigate endometrial expression of Indian Hedgehog (IHH) and genes…

CONTEXT: An active angiogenesis is required for ectopic endometrial tissue growth. Our previous studies led to the identification of macrophage migration inhibitory factor (MIF), which is markedly elevated in active, vascularized, and early…

CONTEXT: Endometrium of fertile women expresses progesterone-regulated Mucin 1 (MUC1) that carries selectin ligands recognized by the human blastocyst. Altered MUC1 expression at the time of implantation may contribute to endometrial infert…

CONTEXT: Somatostatin plays a role in physiological and pathological cell proliferation and angiogenesis. Five subtypes of somatostatin receptors have been identified, and the therapeutic use of somatostatin receptor-selective agonists has …

CONTEXT: Previous studies have implicated a deficiency in the inflammatory response in women who develop endometriosis. The specific immunological deficits have not been completely elucidated. OBJECTIVE: Our objective was to identify diffe…

CONTEXT: Statins are competitive inhibitors of 3-hydroxy-3methylglutaryl-coenzyme A reductase, with antimitotic, antioxidant, antiinflammatory, and immunomodulatory properties. Recent studies have shown that statins reduce the growth of hum…

ContextSex steroid hormone receptor (SHR) dynamics are well-documented in human endometrium but have not been comprehensively studied in Fallopian tube (FT).ObjectiveThe aim of the study was to compare expression patterns and hormonal regul…

CONTEXT: Heavy menstrual bleeding (HMB; menorrhagia) impairs quality of life for women and requires medication or surgery. Because glucocorticoids inhibit angiogenesis in other organs, we hypothesized that endometrium of women with HMB is s…

CONTEXT: Decidualization of the endometrium involves the morphological and biochemical reprogramming of the estrogen-primed proliferative endometrial stromal compartment under the continuing influence of progesterone. OBJECTIVES: The aim o…

CONTEXT: Estrogen and its metabolites play a critical role in the pathophysiology of the endometrium. The bioavailability of estrogen and estrogen metabolites in endometrial tissues depends on the expression of enzymes involved in estrogen …

CONTEXT: Acquisition of ovulatory competence by antral follicles requires development of an adequate vascular supply. Although it is well established that ovarian angiogenesis is cyclically regulated by vascular endothelial growth factor (V…

CONTEXT: The formation of primordial follicles occurs during fetal life yet is critical to the determination of adult female fertility. Prior to this stage, germ cells proliferate, enter meiosis, and associate with somatic cells. Growth and…
