STUDY QUESTION: How does hCG signal in human endometrial stromal cells (ESCs) and what is its role in regulating ESC function? SUMMARY ANSWER: CG signaling in ESCs activates the extracellular signal-regulated protein kinases 1 and 2 (Erk1/2) pathway through exchange protein activated by cAMP (Epac) and transiently increases progesterone receptor (PR) transcript and protein expression and its transcriptional function. WHAT IS KNOWN ALREADY: hCG is one of the earliest embryo-derived secreted signals in the endometrium, which abundantly expresses LH/hCG receptors...

Uterine fibroids are the most common neoplasm of the genital tract in reproductive women. Obesity holds a role as risk factor for uterine fibroids, through hormonal and inflammatory mechanisms. Visceral fat is a hormonally active tissue, so an increase in visceral fat may be considered as a risk factor, through the increased production of inflammatory mediators. The aim of the study was, therefore, to evaluate the association between the presence of uterine fibroids and fat tissue distribution, and to assess the efficacy of both anthropometric and instrumental indicators, in particular the sonographic measurement of preperitoneal fat thickness (PFT) and subcutaneous fat thickness (SFT)...

Endometriosis is a hormone-dependent chronic inflammatory disease characterized by the presence of endometrium beyond the uterine cavity. The disease affects 5-15% of women of child-bearing age, 30-50% of whom suffer from infertility. Understanding the role of dietary factors in the development of endometriosis is critical to development of effective dietary instructions for prevention. Existing studies concerning nutrition and endometriosis suggest that diet is a potentially modifiable risk factor for endometriosis...

OBJECTIVES: Gestational diabetes mellitus (GDM) constitutes one of the most common pregnancy complications and affects 3-5% of all pregnancies, with its incidence still growing. Due to possible maternal and fetal complications, the peripartum management of GDM patients continues to be a debatable issue. The aim of the study was to analyse the course and final way of delivery in women with gestational diabetes mellitus. The effectiveness of induction of labour (IOL) was also assessed and factors predisposing to cesarean section were identified...

In women, the window of implantation is limited to a brief two- to three- day period characterized by optimal levels of circulating ovarian hormones and a receptive endometrium. Although the window of implantation is assumed to occur 8-10 days after ovulation in women, molecular markers of endometrial receptivity are necessary to determine optimal timing prior to embryo transfer. Previous studies showed that members of the bone morphogenetic protein (BMP) family are expressed in the uterus necessary for female fertility; however, the role of BMP7 during implantation and in late gestation is not known...

Context: Uterine leiomyoma (fibroids) are the most common benign tumor in women. Recently, three populations of leiomyoma cells were discovered based on CD34 and CD49b expression, but the molecular differences between these populations remain unknown. Objective: Define differential gene expression and signaling pathways in leiomyoma cell populations. Design: Cells from human leiomyoma were sorted by flow cytometry into three populations: CD34+/CD49b+, CD34+/CD49b-, and CD34-/CD49b-...

Squamous cell carcinoma (SCC) of the uterine cervix occasionally demonstrates a deceptive growth pattern that mimics endocervical crypt involvement by cervical intraepithelial neoplasia, grade 3 (CIN 3). Such CIN 3-like SCCs may be misinterpreted as noninvasive or minimally invasive leading to delays in diagnosis. Little is known of the factors that influence the growth patterns of cervical SCC but we suggested recently that CIN 3-like tumors might demonstrate "collective cellular invasion," which is characterized by a retained epithelial phenotype...

Uterine carcinosarcomas, also known as malignant-mixed mullerian tumors, are rare and highly aggressive tumors whose prognostic factors remain controversial. The stage at the time of presentation is the most important prognostic factor thus far, but little information exists on the prognostic impact of the sarcomatous component (SC) in these tumors. We reviewed 21 cases of uterine carcinosarcomas and estimated the volume of the SC in each case. This information was correlated with the stage of the tumor at presentation...
