A large majority of pregnancy loss in cattle occurs during the first three weeks after conception, particularly during the peri-implantation period. This review integrates established and new information on the biological role of ovarian progesterone (P4), prostaglandins (PGs) and interferon tau (IFNT) in endometrial function and conceptus elongation during the peri-implantation period of pregn...

Background MIF via its receptor, CD74, initiates a signaling cascade that leads to proliferation and survival of cells. Also, MIF binding to CD74 activates p38 signaling pathways that lead to positive effect on the expression of COX-2. The aim of this study was to evaluate the gene expression profile of MIF, CD74 and COX-2 in normal, ectopic and eutopic endometrium during menstrual cycle. The e...

Background: The human endometrium undergoes cyclical changes including proliferation, differentiation, tissue breakdown and shedding (menstruation) throughout a woman’s reproductive life. The postovulatory rise in ovarian progestrone induces profound remodeling in chromatin structure of cells, and consequently differentiation of estradiol-primed endometrium. This change is crucial for embryo im...

Mucin 1 (MUC1) is a diagnostic factor and therapy target in lung adenocarcinoma. MUC1 C-terminal intracellular domain (CD) interacts with estrogen receptor (ER) α and increases gene transcription in breast cancer cells. Because lung adenocarcinoma cells express functional ERα and ERβ, we examined MUC1 expression and MUC1-ER interaction. Because blocking MUC1 CD with an inhibitory peptide (PMIP)...

BACKGROUND Infertility associated with polycystic ovary syndrome (PCOS) could be related to many mechanisms including endometrial factors. OBJECTIVES To review cell adhesion molecule and estrogen receptor expression in the endometrium. SEARCH STRATEGY A systematic review was performed of the Medline and Cochrane databases for papers published in any language between 2004 and 2014. The searc...

AIM OF THE STUDY The objective of this study was to assess the impact of tadalafil on endometrial growth, the uterine artery pulsatility index (PI) and the uterine artery resistance index (RI) in patients under clomiphene ovarian stimulation for intrauterine insemination (IUI). METHODS This randomized crossover study included 30 patients with a normal endometrium over 53 cycles, and 46 of tho...

Background : Mucin (MUC)1 and MUC4 (MUC1, 4) are high molecular weight glycoproteins expressed in normal and malignant epithelial cells, and these expressions are related to the prognosis of some carcinomas. In non-small cell lung carcinoma (NSCLC), the relationship between MUC1, 4 expressions and their prognostic significance is not well known. We evaluated these relationships in a series of N...

The detection of tumor-specific T cells in immunized cancer patients usually relies on lengthy and difficult CTL assays; we now report on flow cytometry to detect the intracellular cytokines interleukin 2 (IL-2), IL-4, IFN-gamma, and tumor necrosis factor alpha (TNF-alpha) produced by CD4+CD69+ and CD8+CD69+ activated T cells after MUC1 antigen stimulation. Peripheral blood mononuclear cells we...

MUC1 mucin is transcriptionally regulated by estrogen, progesterone, and glucocorticoids. Our objective was to determine whether androgen receptor (AR) activation regulates expression of MUC1. The following breast and prostatic cell lines were phenotyped and grouped according to AR and MUC1 protein expression: 1) AR+MUC1 + [DAR17+19 (AR transfectants of DU-145), ZR-75-1, MDA-MB-453, and T47D]; ...

INTRODUCTION The presence of MUC5AC (M1 antigen) and MUC6 have previously been found in ovarian mucinous cyst. We characterized the mucins in the crude mucus and tissue of a mature ovarian teratoma in an 8 year old girl. MATERIALS AND METHODS Mucins were purified from crude mucus by density gradient ultra-centrifugation in CsCl and analysed by gel-filtration and SDS-PAGE analysis. Mucin ident...
