CRH, the hypothalamic component of the hypothalamic-pituitary adrenal axis, attenuates inflammation through stimulation of glucocorticoid release, whereas peripherally expressed CRH acts as a proinflammatory mediator. CRH is expressed in th…

The ribonuclease III endonuclease, Dicer1 (also known as Dicer), is essential for the synthesis of the 19-25 nucleotide noncoding RNAs known as micro-RNAs (miRNAs). These miRNAs associate with the RNA-induced silencing complex to regulate g…

Chorionic gonadotropin (CG) is indispensable for human pregnancy because it controls implantation, decidualization, and placental development. However, its particular role in the differentiation process of invasive trophoblasts has not been…

The pro-angiogenic factor cysteine-rich protein 61 (CYR61/CCN1) mediates different signals in tumorigenesis, angiogenesis and is involved in the pathogenesis of endometriosis. In this study we investigated the temporal and spatial expressio…

Leptin, a 16-kDa cytokine, has been implicated in several reproductive processes and disorders. Notably, elevated leptin levels in the peritoneal fluid of women with mild endometriosis has been demonstrated, suggesting a role for this cytok…

Endometriosis is a debilitating disease characterized by the presence of functional endometrial glandular epithelium and stroma outside the uterine cavity that affects up to 20% of women of child-bearing age. Cyclooxygenase-2 (COX-2), a rat…

The current dogma surrounding endometrial regeneration after menses includes a critical need for estrogen-primed proliferation. Although some evidence suggests that estrogen may not be required for the initial reepithelialization of the ute…

The identification of molecular differences in the endometrium of women with endometriosis is an important step toward understanding the pathogenesis of this condition and toward developing novel strategies for the treatment of associated i…

Aberrant up-regulation of aromatase in eutopic endometrium and implants from women with endometriosis has been reported. Aromatase induction may be mediated by increased cyclooxygenase-2 (COX-2). Recently, we demonstrated that progesterone …

IL-17A is secreted from Th17 cells, a discovery leading to revision of the mechanism underlying the role of Th1/Th2 in the immune response. Strong evidence suggests that immune responses associated with inflammation are involved in the path…

Suppression of the hypothalamic-pituitary-gonadal axis by peptides that act at the GnRH receptor has found widespread use in clinical practice for the management of sex-steroid-dependent diseases (such as prostate cancer and endometriosis) …

The effect of continuous administration of the C-terminal fragment of metastin, the ligand for the G protein-coupled receptor, GPR54, on GnRH-induced LH secretion was examined in three agonadal, juvenile male monkeys whose responsiveness to…

Adiponectin, a pleiotropic cytokine, exerts its effects via the specific receptors AdipoR1 and AdipoR2. Whereas circulating adiponectin concentrations decrease in women with endometriosis and endometrial cancer, possible effects of adiponec…

Substantial evidence suggests that inflammatory cytokines, immune cells, and angiogenesis are important for endometriosis. In this study, we investigated the role of the sequential events in the development of endometriosis in a mouse model…

Infiltrating neutrophil granulocytes are a particularly rich source of vascular endothelial growth factor (VEGF) in the endometrium and may contribute to the angiogenesis of endometriosis lesions. The objective of this study is to evaluate …

Raloxifene (RAL) is a selective estrogen receptor modulator presenting tissue-specific agonist activity. The aim of this study was to examine whether RAL has an estrogenic effect on carrageenan-induced acute inflammation. Adult female rats …

Pelvic pain is a common presenting ailment in women often linked to ovulation, endometriosis, early pregnancy, ovarian cancer, and cysts. Clear differential diagnosis for each condition caused by these varied etiologies is difficult and may…

Endometriosis, defined as the presence of endometrial glandular and stromal cells outside the uterine cavity, is a common gynecological disease with poorly understood pathogenesis. Using laser capture microdissection and a cDNA microarray w…

The periimplantation period is marked by edematous changes in the uterus. In the mouse, increased uterine vascular permeability occurs in response to estrogen and certain vasoactive mediators, but the mechanisms that regulate fluid transpor…

Endometriosis is clinically associated with pelvic pain and infertility, with implantation failure strongly suggested as an underlying cause for the observed infertility. Eutopic endometrium of women with endometriosis provides a unique exp…

IL-11 is a member of the gp130 family of cytokines, which signal via assembly of multisubunit receptor complexes containing at least one molecule of the transmembrane signaling receptor gp130. IL-11 forms a high-affinity complex, thereby in…

Steroidogenic acute regulatory protein (StAR) regulates the first committed step in the biosynthesis of steroids, and thus aberrant expression of StAR in endometriotic implants plays a critical role in the etiology of endometriosis. However…

A fully functional FSH receptor (Fshr) is required for ovarian follicular development and fertility. Fshr null females are sterile because of failure of follicular maturation, ovulation, and estrogen deficiency. Because Fshr-haploinsufficie…

We have demonstrated previously that both rat and human liver microsomes contain a highly specific binding protein for the anabolic steroids stanozolol (ST) and danazol (DA). In this study we solubilized the male rat liver ST-binding protei…

Dioxin (2,3,7,8-tetrachlorodibenzo-p-dioxin; TCDD) is the most toxic congener of a large class of environmental pollutants. Several studies have shown that TCDD exposure reduced fecundity and ovulatory rate in rats and increased the inciden…
