diapause. Pafr protein was present in a membrane bound form in the glandular epithelium of the endometrium across all stages, analysis studies are in progress to determine any temporal changes in levels of expression. In vitro, paf production from the endometrium increases after diapause (Kojima et al., 1993). p53 expression assessed by RT-PCR, was detected in the endometrium across all stages ...

OBJECTIVE This study was undertaken to assess baseline endometrial molecular events in the ATAC (Arimidex, tamoxifen, alone, or in combination) trial of breast cancer adjuvant therapy. STUDY DESIGN Estrogen receptor (ER) and progesterone receptor (PR) levels and markers of cell proliferation (Ki67) and apoptosis ( Bcl -2) were assessed in 93 patients at baseline. RESULTS An inactive/atrophi...

BACKGROUND Apelin is a mitogenic peptide; it has functions in vessel formation and cell proliferation. In this study we aimed to evaluate the serum and tissue levels and local expression pattern of apelin in eutopic and ectopic endometrium from patients with and without endometriosis and to compare the proliferative and secretory phase differences. METHODS Thirty women with endometriosis and ...

BACKGROUND Different molecular alterations have been described in endometrioid endometrial carcinoma (EECA). Among them the most frequently altered is loss of the PTEN protein, a tumor suppressor gene. The purpose of this study was to evaluate the expression pattern of PTEN gene in normal, hyperplastic and neoplastic endometrium. METHODS In a study in a referral gynecologic hospital in Tehran...

PROBLEM Macrophages are recruited in large number to the interplacentomal endometrium of the cow during pregnancy. We evaluated whether endometrial macrophages also accumulate in placentomal regions of endometrium during pregnancy and whether endometrial macrophages are regionally differentiated. METHOD OF STUDY Interplacentomal endometrium and placentomes were subjected to dual-color immunof...

BACKGROUND To clarify the inflammatory nature of adenomyosis, we aimed to investigate the expression of interleukin-8 (IL-8) and monocyte chemotactic protein-1 (MCP-1) by immunohistochemistry to determine their putative role in pathophysiology of adenomyosis. METHODS Adenomyosis samples, with their eutopic endometrium, were collected from 30 women undergoing hysterectomy. Endometrium from 27 ...

BACKGROUND The objectives of this study were: (i) to evaluate the effects of the levonorgestrel-releasing intrauterine system (LNG-IUS) on both proliferation and apoptosis markers and hormone receptors of the eutopic and ectopic endometrium of women experiencing pain related to endometriosis and (ii) to compare the results with those obtained with GnRH agonist (GnRHa) injections. METHODS Pre-...

BACKGROUND It is becoming increasingly evident that the eutopic endometrium of women with endometriosis shows certain genetic alterations which are not found in the endometrium of disease-free women. The aim of the study was to compare the expression level of mammalian target of rapamycin (mTOR) tumor suppressor and oncogene-related genes in the endometrium of women with and without endometrios...

We developed an in vitro suspension co-culture system to examine the interaction of 1st, 2nd and 3rd trimester purified cytotrophoblasts with human endometrium. Endometrium explants were added to cytotrophoblast cell suspensions and placed on an angled gyrating platform in a 37 degrees C incubator. When endometrium was cultured alone it was able to remain viable for up to 3 days. When trophobla...
