More than 25% of patients diagnosed with endometrial carcinoma have invasive primary cancer accompanied by metastases. Growth hormone-releasing hormone (GHRH) plays an important role in reproduction. Here, we examined the effect of a GHRH antagonist on the motility of endometrial cancer cells and the mechanisms of action of the antagonist in endometrial cancer. Western blotting and immunohistoc...

The potential anticancer agent 1-(2-chlorophenyl-N-methylpropyl)-3-isoquinolinecarboxamide (PK11195), a translocator protein ligand, facilitates the induction of cell death by a variety of cytotoxic and chemotherapeutic agents in various human tumor cell lines. The purpose of this study was to elucidate the effect of PK11195 on three endometrial cancer cell lines, two ovarian cancer cell lines ...

UNLABELLED OBJECTIVE[S]: Activin A and inhibin A are growth factors expressed by human endometrium involved in the control of endometrial functions. In the present study we investigated the effects of activin A and inhibin A in modulating the tumor necrosis factor (TNF)-alpha/intercellular adhesion molecule (ICAM)-1 system in cultured human endometrial stromal cells. STUDY DESIGN Endometrial ...

BACKGROUND Eukaryotic chromosomal ends are linear and are protected by nucleoprotein complexes known as telomeres. The complex structural anatomy and the diverse functions of telomeres as well as the unique reverse transcriptase enzyme, telomerase that maintains telomeres are under intensive scientific scrutiny. Both are involved in many human diseases including cancer, but also in ageing and c...

PURPOSE Research has revealed abnormal activation of the hedgehog pathway in human malignancies. The present study was undertaken to examine the expression and functional involvement of the hedgehog pathway in endometrial tissues. EXPERIMENTAL DESIGN The expression of sonic hedgehog (Shh), patched (Ptch), Smoothened (Smo), and Gli1 was examined in various endometrial tissues and endometrial c...

BACKGROUND Evidence suggests that eutopic endometrium from women with endometriosis (US-E) has intrinsic functional anomalies compared with women without endometriosis (US-C). We hypothesized that differences in endometrial haptoglobin (eHp) mRNA and protein levels exist between eutopic endometrium from US-E and US-C and that inflammatory mediators may be involved. METHODS Endometrial stromal...

Glycodelin contains four isoforms with diverse biological functions. Glycodelin-A is potentially a diagnostic marker for cancer patients and receptivity marker of the secretory endometrium. Yet, direct evidence for the role of glycodelin in the regulation of endometrial epithelial cell migration, invasion and attachment of trophoblastic spheroids (blastocyst surrogate) is lacking. In this study...

PURPOSE To evaluate the prognostic value of vascular endothelial growth factor (VEGF)-D and VEGF receptor (VEGFR)-3 in endometrial carcinoma. EXPERIMENTAL DESIGN We assessed the levels of immunoreactivity for VEGF-D and VEGFR-3 in 71 endometrial carcinomas, 14 complex atypical endometrial hyperplasias, and 16 normal endometria by immunohistochemistry. RESULTS VEGF-D was stained in both tumo...

Objective : Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders that can lead to irregular menstrual cycles and hyperandrogenism. Reduced levels of progesterone and increased estrogen in these women can perpetually stimulate the endometrial tissue of the uterus. In this study, the effect of PCOS induction was studied using estradiol valerate. MaterialsAndMethods Adult ...

BACKGROUND It was unclear whether chronic endometrial ischemia contributed to the pathogenesis of thin endometrium and was associated with decreased endometrial stem/progenitor cell. Thus, we explored the role of chronic endometrial ischemia in the pathogenesis of thin endometrium and its effect on endometrial stem/progenitor cells apoptosis. MATERIAL/METHODS In vitro, endometrial side popula...
