OBJECTIVES We describe the morphologic and immunohistochemical features of 17 endometrial stromal neoplasms, 16 sarcomas, and one stromal nodule. METHODS We reviewed 35 cases interpreted as endometrial stromal neoplasms, but 17 high-grade endometrial stromal sarcomas (ESS) and one case of mixed endometrial sarcoma and leiomyosarcoma were excluded from the study. Data from the Surveillance Epi...

Calpains have been implicated in the regulation of apoptosis. Here, we identified Calpain5 as a target of HOXA10 transcriptional regulation in endometrial cells as well as its aberrant regulation in endometriosis. Histologically confirmed biopsies of endometriosis were obtained from 20 women. Eutopic endometrium was collected by endometrial biopsy from 30 controls and from the 20 subjects with ...

OBJECTIVE HOXA10 is an essential regulator of endometrial receptivity. To determine the effect of GnRH antagonists on endometrial receptivity, we assessed endometrial HOXA10 expression in GnRH antagonist, GnRH agonist, and natural cycles. DESIGN Prospective case-control study. SETTING University academic medical center. PATIENT(S) Nineteen subjects were included: 12 subjects underwent con...

Lysophosphatidic acid (LPA) is a pleiotropic phospholipid molecule involved in inflammation, angiogenesis, would healing, and cancer invasion. Whereas serum lysophospholipase D activity increases in women with pregnancy, the role of LPA in pregnancy remains unclear. We investigated the expression of LPA receptors and function of LPA in endometrial stromal cells. Histologically normal endometriu...

Rare cells with adult stem cell activity were recently discovered in human endometrium. Endometrial stem/progenitor cell candidates include epithelial, mesenchymal and endothelial cells, and all may contribute to the rapid endometrial regeneration following menstruation, rather than a single candidate. Endometrial mesenchymal stem-like cells (eMSC) are prospectively isolated as CD146+PDGF-Rb+ c...

Endometrial Stromal Tumor is a rare malignant tumor seen in perimenopausal women. This case of stromal tumour young nulliparous woman around her early thirties mimicking Fibroid uterus. She presented with 34 weeks size mass abdomen six months duration without any menstrual irregularities. The was diagnosed to be huge sub serous fibroid by both clinical and ultrasonographic examination. MRI reve...

Interleukin (IL)-6, leukaemia inhibitory factor (LIF) and IL-11 belong to the same family of cytokines whose receptors utilize gp130 as the signalling molecule. We have investigated the expression of the IL-11 receptor, IL-11Ralpha, protein in the human endometrium in vivo and the effects of IL-6, LIF and IL-11 on the production of metalloproteinases (MMPs) and cytokines by cultured endometrial...

Decidualization is a crucial change required for successful embryo implantation and the maintenance of pregnancy. During this process, endometrial stromal cells differentiate into decidual cells in response to the ovarian steroid hormones of early pregnancy. Extracellular signal-regulated protein kinases 1 and 2 (ERK1/2) are known to regulate cell proliferation and apoptosis in multiple cell ty...

BACKGROUND Endometrial stromal sarcoma (ESS) is a rare disease with probably less than 700 new cases in the USA or Europe per year. The aim of this study was to evaluate the behavior of low-grade endometrial stromal sarcoma (LGESS) in relation to their clinical and pathological features and to identify possible prognostic factors. PATIENTS AND METHODS Fourteen patients with histologically pro...

background: endometrial remodeling occurs during each menstrual cycle in women. reports have shown that, in a variety of cell types, processes such as proliferation, signaling complex formation and extra cellular matrix remodeling require a cytoplasmic tyrosine kinase, focal adhesion kinase (fak). the present study has focused on the expression pattern of fak in human endometrium during the men...
