Endometriosis, a disease affecting 3% to 10% of women of reproductive age, is characterized by the ectopic growth of endometrial tissue under the influence of estrogen. It is also becoming recognized as a condition in which ectopic endometrial cells exhibit abnormal proliferative and apoptotic regulation in response to appropriate stimuli. Apoptosis plays a critical role in maintaining tissue h...

BACKGROUND Endometriosis, a common chronic inflammatory disorder, is defined by the atypical growth of endometrium- like tissue outside of the uterus. Secretory phospholipase A2 group IIa (sPLA2-IIa) and fatty acid binding protein4 (FABP4) play several important roles in the inflammatory diseases. OBJECTIVE Due to reported potential anti-inflammatory effects of ω-3 and ω-6 fatty acids, the pu...

With the goal of identifying diagnostic and prognostic biomarkers in endometrial cancer, miRNA-profiling was carried out with formalin-fixed paraffin embedded (FFPE) tissue samples from 49 endometrial cancer patients. Results using an 84-cancer specific miRNA panel identified the upregulation of miR-141-3p and miR-96-5p along with a downregulation of miR-26, miR-126-3p, miR-23b, miR-195-5p, miR...

OBJECTIVE To compare progesterone concentrations in serum and endometrial tissue from hysterectomy specimens after vaginal or intramuscular (IM) administration of progesterone gel. METHODS This was a randomized open study of 14 post-menopausal women undergoing transabdominal hysterectomies. Participants received either vaginal progesterone gel, 90 mg, or IM progesterone, 50 mg, at 8:00 AM and...

Lymphoid tissue of the endometrium was analysed by histological, immunohistological, and electron microscopical methods in 10 healthy uteri. A panel of monoclonal antibodies recognising macrophages (OKMI), HLA-DR antigen, B lymphocytes, T lymphocytes and their subsets, and dendritic reticulum cells was used in a two stage indirect immunoperoxidase labelling technique. Endometrial lymphoid tissu...

Adult stem cells have recently been identified in several types of mature tissue and it has also been suggested that stem-like cells exist in cancerous tissues. In this regard, stem-like cell subpopulations, referred to as side-population (SP) cells, have been identified in several tissue and tumor types, based on their ability to remove intracellular Hoechst 33342, a fluorescent dye. We have i...

BACKGROUND Apoptosis occurs in late secretory and menstrual human endometrium and is thought to play an important role in endometrial physiology. Menstrual-like breakdown has been observed in vitro in endometrial explants. The purpose of this study was to assess the role of apoptosis in menstrual-like breakdown in human endometrial explants. METHODS Human endometrial tissue was obtained durin...

Endometriosis is an adhesion disorder characterized by the presence of endometrial tissue in ectopic sites outside the uterus. The disease is associated with dysmenorrhea, pelvic pain and infertility. Although endometriosis is the most common gynecologic disorder, relatively little is known regarding its etiology, pathogenesis and the course of the disease. This situation is primarily due to th...

Endometriosis, a disease affecting 3-10% of women of reproductive age, is characterized by the ectopic growth of endometrial tissue. Increasingly, endometriosis is also becoming recognized as a condition in which ectopic endometrial cells exhibit abnormal proliferative and apoptotic regulation in response to appropriate stimuli. Apoptosis plays a critical role in maintaining tissue homeostasis ...

Embryo implantation requires a healthy embryo and a receptive endometrium (inner lining of the uterus); endometrial receptivity acquisition involves considerable epithelial surface remodeling. Dystroglycan (DG), a large cell surface glycoprotein, consists of α- and β-subunits; β-DG anchors within the plasma membrane whereas α-DG attaches extracellularly to β-DG. The glycosylated central α-DG me...
