Extracellular lysophosphatidic acid (LPA) and the G-protein-coupled LPA receptors (LPAR) are involved in cell migration and invasion and found in the human endometrium. However, underlying mechanisms resulting in cellular invasion have been…

The adherens junction associated protein 1 (AJAP1, aka shrew-1) is presumably a type-I transmembrane protein localizing and interacting with the E-cadherin-catenin complex. In various tumors, AJAP1 expression is reduced or lost, including h…

BACKGROUND: A substantial body of studies supports the view that molecular and cellular features of endometriotic lesions differ from those of eutopic endometrium. Apart from that, evidence exists that the eutopic endometrium from pa-tients…

Endometriosis is characterized by growth of endometrial tissue at ectopic locations. Down-regulation of microRNA miR-200b is observed in endometriosis and malignant disease, driving tumour cells towards an invasive state by enhancing epithe…

In the endometrium transforming growth factor-betas (TGF-βs) are involved mainly in menstruation and endometriosis. After binding of the ligands to the high-affinity receptors, TGF-β receptors (TBR1 and TBR2), TGF-βs activate Smad signaling…

ObjectiveTo study the expression and function of syndecan-4 in endometriosis.DesignHistopathological investigation of eutopic endometrium and experimental laboratory study on a cell line derived from epithelial endometriotic cells (12Z).Set…

Endometriosis is a debilitating, estrogen-dependent, progesterone-resistant, inflammatory gynecological disease of reproductive age women. Two major clinical symptoms of endometriosis are chronic intolerable pelvic pain and subfertility or …

Endometriosis is an inflammatory gynecological disease of reproductive-age women. The prevalence of endometriosis is 5-10% in reproductive-age women. Modern medical treatments are directed to inhibit the action of estrogen in endometriotic …

BACKGROUND: Endometriosis is characterized by the presence of functional endometrial tissue outside of the uterine cavity. It affects 1 in 10 women of reproductive age. This chronic condition commonly leads to consequences such as pelvic pa…

OBJECTIVE: To study the function of miR-145, known to be dysregulated in endometriosis, and to identify its target genes in an in vitro endometriosis model. DESIGN: Experimental laboratory study. SETTING: University medical centers. PATI…

Endometriosis is a chronic gynecological disease of reproductive age women characterized by the presence of functional endometrial tissues outside the uterine cavity. Interactions between the endometriotic cells and the peritoneal extracell…

ObjectiveTo study the function of syndecan-1 (SDC1) and its potential regulator miR-10b in endometriosis.DesignExperimental laboratory study.SettingUniversity medical center.Patient(s)Not applicable.Intervention(s)The human endometriotic ce…

BACKGROUND: Novel therapeutic approaches for endometriosis based on molecular strategies may prove to be useful. Conditionally replicative adenoviruses (CRAds) are designed to exploit key differences between target and normal cells. The wil…

OBJECTIVE(S): To determine whether nuclear factor-kappaB (NF-kappaB) is constitutively and tumor necrosis factor (TNF)-dependently activated in endometriotic cells, whether trichostatin A (TSA) can suppress NF-kappaB activation and suppress…

The use of anti-L1-cell adhesion molecule monoclonal antibodies (anti-L1CAM-mAb) in an endometriosis epithelial cell line Z12 led to a statistically significant decrease in cell proliferation and cell invasion and to an inhibition of the ad…

OBJECTIVE: To determine interactions between prostaglandin (PG) E(2) signaling and proliferation of endometriotic cells to increase our knowledge about PGE(2) signaling in the pathogenesis of endometriosis in humans. DESIGN: Immortalized h…

Prostaglandin E2 (PGE2) plays an important role in the pathogenesis of endometriosis. We recently reported that inhibition of COX-2 decreased migration as well as invasion of human endometriotic epithelial and stromal cells. Results of the …

Endometriosis is a benign chronic gynecological disease of reproductive-age women characterized by the presence of functional endometrial tissues outside the uterine cavity. It is an estrogen-dependent disease. Current treatment modalities …

Treatment of immortalized stromal-like and epithelial-like endometriotic cells with capsaicin resulted in inhibition of proliferation in a concentration-dependent manner. In addition, endometriotic cells are more sensitive to capsaicin trea…

Targeting signals direct proteins to their extra- or intracellular destination such as the plasma membrane or cellular organelles. Here we investigated the structure and function of exceptionally long signal peptides encompassing at least 4…

ObjectiveTo determine whether a mixed population of immortalized human endometriosis epithelial and stromal cells is able to induce peritoneal endometriosis in nude mice.DesignProspective experimental study. Human immortalized endometriosis…

Tumor necrosis factor (TNF)-alpha is central to the endometriotic disease process. TNF-alpha receptor signaling regulates epithelial cell secretion of inflammation and invasion mediators. Because epithelial cells are a disease-inducing comp…

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…

ObjectiveTo determine whether immortalized endometriotic cells can be used as potential models to unravel pathophysiology/pathogenesis of endometriosis in humans.DesignIn vitro study. Human immortalized endometriotic epithelial and stromal …

Shrew-1 was previously isolated from an endometriotic cell line in our search for invasion-associated genes. It proved to be a membrane protein that targets to the basolateral membrane of polarized epithelial cells, interacting with E-cadhe…
