It is clear that estrogen can accelerate and exacerbate disease in some lupus-prone mouse strains. It also appears that estrogen can contribute to disease onset or flare in a subset of patients with lupus. We have previously shown estrogen alters B-cell development to decrease lymphopoiesis and increase the frequency of marginal zone B cells. Furthermore, estrogen diminishes B-cell receptor sig...
PURPOSE THE AIMS OF THIS STUDY WERE AS FOLLOW: 1) to de scribe the expression status of estrogen receptor-α and -β mRNAs in five gastric carcinoma cell lines; 2) to evaluate in vitro the effects of 17β-estradiol and estrogen receptor antagonists on the proliferation of the cell lines. MATERIALS AND METHODS Detection of estrogen receptor-α and estrogen receptor-β mRNA in five human gastric can...
some lesions in the oral cavity and mostly on gingiva have predominant predilection towards females, and mostly occur in the first four decades of life when changes in sex hormone levels in blood are obvious. the present study aimed to investigate the presence and distribution of estrogen and progesterone receptors in peripheral giant cell granuloma (pgcg), pyogenic granuloma (pg) and periphera...
Clinical trials and animal studies have revealed that loss of circulating estrogen induces rapid changes in whole body metabolism, fat distribution, and insulin action. The metabolic effects of estrogen are mediated primarily by its receptor, estrogen receptor-α; however, the detailed understanding of its mechanisms is incomplete. Recent investigations suggest that estrogen receptor-α elicits t...
Silibinin is a natural flavonoid with anti-diabetic activity. Glucagon-like peptide−1 (GLP−1), an intestinal hormone mainly secreted from L cells, which regulates insulin production and sensitivity, appears to be potential therapeutic strategy for T2DM. The current study aims determine the protective effect of silibinin against palmitic acid (PA)-induced damage in GLUTag cells. results revealed...
Psychological stress contributes to the development of hypertension in humans. The ovarian hormone, estrogen, has been shown to prevent stress-induced pressor responses in females by unknown mechanisms. Here, we showed that the antihypertensive effects of estrogen during stress were blunted in female mice lacking estrogen receptor-α in the brain medial amygdala. Deletion of estrogen receptor-α ...
background: the etiology of breast cancer and our understanding on the carcinogenicity of different risk factors is impotant for control programms. objective: we investigated the expression of estrogen and progesterone receptors (er, pr), and human epithelial receptor 2 (her2) overexpression and its associations, with environmental risk factors among breast cancer patients. methods: we classif...
background: papillary thyroid carcinoma (ptc), occurs mostly in women and sex hormones may play a role in the pathogenesis and clinical course. the objective of this study was to determine the status and prevalence of estrogen and progesterone receptors in ptc with regard to age, gender, tumor size and lymph node involvement. methods: immunohistochemical stains were performed on 92 tissue block...
