Various matrix metalloproteinases (MMPs) participate in the menstrual breakdown of the human endometrium. MMP-9/gelatinase B is proposed as a major factor because it degrades many extracellular matrix constituents, including in the vasculature. Although globally under ovarian steroids control, endometrial MMP-9 seems expressed differently than other MMPs, and conflicting publications prevent a ...

background: poor ovarian response to controlled ovarian stimulation is one of the most important interest points in assisted reproduction. mild ovarian stimulation seems to be preferable to high dose of fsh regimens in women with a history of poor ovarian response in previous protocol. clomiphene citrate and letrozole alone or in combination with fsh have been used in mild ovarian stimulation p...

Cancer immunotherapy is hampered by the immunosuppression maintained by regulatory T cells (Tregs) in tumor-bearing hosts. Stimulation of the Toll-like receptor 2 (TLR2) by Pam3Cys is known to affect Treg-mediated suppression. We found that Pam3Cys increases the proliferation of both CD4(+) effector T cells (Teffs) and Tregs co-cultured in vitro, but did not induce the proliferation of Tregs al...

Signal transducer and activator of transcription 3 (STAT3) is aberrantly activated in human cancer including lung cancer and has been implicated in transformation, tumorigenicity, and metastasis. One putative downstream gene regulated by Stat3 is MUC1 which also has important roles in tumorigenesis. We determined if Stat3 regulates MUC1 in lung cancer cell lines and what function MUC1 plays in ...

Mucin 1 (MUC1) is a large transmembrane glycoprotein that is aberrantly overexpressed in most adenocarcinomas and certain hematological malignancies. MUC1 is known to function as an oncogene with roles in both tumor formation and progression, making it a potential target for immunotherapy. B16-MUC1 cells with human full-length MUC1 are frequently used to study the antitumor activities of MUC1-b...

Lysophosphatidic acid (LPA) known as a serum-derived growth factor, is involved in several cell physiological functions in the female reproductive system including: oocyte maturation, in vitro fertilization and embryo implantation by its transmembrane G protein-coupled receptors. The aim of the present study was to examine the effect of LPA on in vitro follicular development o...

background: the preparation of endometrium for embryo reception and implantation are controlled by ovarian hormones. these hormones have distinct cyclical changes during estrus cycle. objective: the aim of this study was to evaluate the changes in morphology and morphometrical indices of endometrium by daily injections of estrogen and progesterone in ovariectomized mouse. materials and methods:...

The anti-inflammatory function of tanshinone IIA (TIIA), an active natural compound from Chinese herbal medicine Danshen, has been well recognized, and therefore TIIA has been widely used to treat various inflammatory conditions associated with cardiac and lung diseases. Mucin 1 (Muc1) plays important anti-inflammatory roles in resolution of acute lung inflammation. In this study, we investigat...

Introduction In the swine farms, the reproductive disorders composed of repeat breeding, vaginal discharge, anestrus, not getting pregnant and abortion are the main problem resulting in culling lots of gilts (1). It is known that reproductive function of gilts is complicated to clinically explore under field surroundings, thus the reproductive organs from the slaughterhouses are the possible so...

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