Artemin a member of the glial cell line-derived neurotrophic factor (GDNF) family is present in mice and human preimplantation embryos, and reproductive tract, during early pregnancy promoting embryo development in vitro. The presence of artemin in cattle embryos and reproductive tract, however, is unknown. In the present work we identified for first time artemin in bovine uterine fluid (UF) (Western blot), endometrium (RT-PCR, Western blot and immunohistochemistry) and embryos (RT-PCR and immunohistochemistry) during early preimplantation development...

PROBLEM: Endometriosis is a chronic inflammatory disease associated with an impairment in immune response. Disorders in the peritoneal fluid and ectopic endometrium macrophage populations and their secretory products create a specific microenvironment inducing the development of the disease. The important factors involved in inflammation associated with endometriosis are chemokines, especially interleukin (IL)-8. For this reason, the current study briefly reviews the role of IL-8 in the pathogenesis of endometriosis...

Persistent organic pollutants (POPs) are ubiquitously distributed among the U.S. population and adversely impact human reproduction. These compounds have been detected in human ovarian follicular fluid (FF), where they directly contact a developing oocyte. As a pilot investigation, we measured 43 polychlorinated biphenyl (PCB) congeners, p,p'-dichlorodiphenyltrichloroethane (DDT), and its persistent metabolite p,p'-dichlorodiphenyldichloroethylene (DDE) in residual FF collected from 32 women undergoing in vitro fertilization (IVF)...

The preimplantation ultrasound (US) refers to targeted imaging of the uterus and adnexa prior to assisted reproductive techniques (ART) to optimize the infertility treatment outcomes. After a thorough evidence based literature review, we propose the use of transvaginal three-dimensional (3D) US during the early follicular phase. A systematic approach for 3D US examination consists of a detailed examination of the uterine shape, size and contour, evaluation of the endometrial thickness, volume, pattern and vascularity, and assessment of the junctional zone regularity, echogenicity and thickness...

Previous studies have shown that Lycium barbarum polysaccharides (LBPs) serve an important role in antioxidant activity to protect the cells and tissues. However, the specific mechanism of LBPs in the prevention of endometrial damage remains to be elucidated. Using morphological observation, cell proliferation assay, the detection of superoxide dismutase (SOD) activity and the content of malondialdehyde (MDA) in cell culture supernatant fluid, the detection by western blot analysis and reverse transcription-quantitative polymerase chain reaction of the mRNA and protein expression levels of caspase‑3 and Bcl‑2 in endometrial stromal cells (ESCs), it was demonstrated that, in vitro, hydrogen peroxide (H2O2)-induced death of ESCs, increased the content of MDA and decreased the activity of SOD, and decreased the expression of Bcl-2 and increased the expression of caspase‑3...

BACKGROUND: Endometrial cancer is the most common gynecologic malignancy, and its incidence and associated mortality are increasing. Despite the immediate need to detect these cancers at an earlier stage, there is no effective screening methodology or protocol for endometrial cancer. The comprehensive, genomics-based analysis of endometrial cancer by The Cancer Genome Atlas (TCGA) revealed many of the molecular defects that define this cancer. Based on these cancer genome results, and in a prospective study, we hypothesized that the use of ultra-deep, targeted gene sequencing could detect somatic mutations in uterine lavage fluid obtained from women undergoing hysteroscopy as a means of molecular screening and diagnosis...

From previous cDNA subtraction studies analyzing gene expression in equine endometrium, high lipocalin 2 (LCN2) mRNA expression was found in the gravid endometrium. In the uterus, LCN2 may transport hydrophobic molecules and siderophores with iron, or may form a complex with another protein, however, the expression of uterine LCN2 beyond day 20 of equine pregnancy and its receptor has not been characterized. To study the expression and potential roles of uterine LCN2 from pre-implantation to mid-gestation period, stage-specific endometrial samples were obtained from day 13 (day 0 = ovulation) cyclic and days 13, 19, 25, and 60 to 131 pregnant mares...

Emerging evidence shows that some of the pro-inflammatory cytokines are elevated not only in the endometrium but also in the follicular fluid of cows with endometritis. Developing a cervico-vaginal mucus (CVM) based test has the potential for becoming a pen-side test because of the ease of sample collection. The present study describes the results of two different experiments. The first experiment was conducted to investigate the influence of endometritis on the proinflammatory cytokines of follicular fluid based on the reproductive tracts of buffalo collected at a slaughter house Buffalo genitalia were categorized into purulent endometritis (PE), cytological endometritis (CE), and non-endometritis (NE) based on the white-side test and endometrial cytology, respectively (n = 14/group)...

Endometriosis is an estrogen-dependent disease. We previously found that the expression of Activin A was upregulated in the peritoneal fluid of patients with endometriosis. The results of the present study indicated that Activin A induced estradiol secretion and P450arom expression in endometrial stromal cells (ESCs) derived from endometriosis patients. The mechanism of estrogenic synthesis was regulated by the Activin-Smad pathway in endometrial lesions. The data showed that the effect of Activin A on ESCs was partially abrogated by pretreatment with an inhibitor of ALK4 (the type I receptor, ActRIB) and Smad4-siRNA...
