Although it is well appreciated that ovarian stimulation protocols for in vitro fertilization (IVF) alter endometrial receptivity, the precise cellular mechanisms are not known. To gain insights into potential mechanisms by which different …

Vaginal bleeding and subchorionic hematomas are associated with increased risk of both early and late pregnancy loss. Thrombin generation may play a pivotal role in the development of these complications. To determine the effects of thrombi…

MicroRNAs (miRs) are small molecules important for regulation of transcription and translation. The objective was to identify hormonally regulated miRs in human endometrial stromal cells and to determine the impact of the endocrine disrupto…

BackgroundAndrogenic compounds have been implicated in induction of endometrial atrophy yet the mechanisms of androgen effects on human endometrium have not been well studied. We hypothesized that androgens may promote their endometrial eff…

STUDY QUESTION: How does progesterone alter matrix remodeling in abdominal wall endometriomas compared with normal endometrium? SUMMARY ANSWER: Progesterone may prevent attachment of endometrial cells to the abdominal wall, but does not ame…

ObjectiveReconstructive surgery for pelvic organ prolapse is plagued with high failure rates possibly due to impaired healing or regeneration of the vaginal wall. Here, we tested the hypothesis that postoperative administration of local est…

For successful embryo implantation, endometrial stromal cells must undergo functional and morphological changes, referred to as decidualization. However, the molecular mechanisms that regulate implantation and decidualization are not well d…

Mice deficient for the fibulin-5 gene (Fbln5(-/-)) develop pelvic organ prolapse (POP) due to compromised elastic fibers and upregulation of matrix metalloprotease (MMP)-9. Here, we used casein zymography, inhibitor profiling, affinity pull…

BackgroundDuring 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 uteropl…

Pelvic organ prolapse (POP) is a common condition affecting almost half of women over the age of 50. The molecular and cellular mechanisms underlying this condition, however, remain poorly understood. Here we have reported that fibulin-5, a…

CONTEXT: Up-regulation of aromatase expression in endometrial cells disseminated into the peritoneal cavity may enhance their survival via local estrogen synthesis, which may lead to endometriosis. The factors that mediate induction of arom…

Large conductance K( +) channels (BK(Ca)) are expressed in uterine artery (UA) smooth muscle from nonpregnant and pregnant sheep and contribute to the regulation of basal vascular tone and responses to estrogen and vasoconstrictors. To dete…

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 …
