Effect of estradiol -17 β on arachidonic acid metabolism in sheep uterus: in vitro studies
The effect of estradiol-17 β on Arachidonic acid (AA) metabolism in non-pregnant sheep uterus was studied under in vitro conditions. On incubation of uterine slices with estradiol-17β, the levels of prostaglandins were altered but not Lipoxygenase (LOX) products. Based on their analysis on conventional TLC technique, the Cyclooxygenase (COX) products PGF2α, 6-keto PGF1α and PGE2 were shown to b...
متن کامل17-β Estradiol regulates proglucagon-derived peptide secretion in mouse and human α- and L cells.
Clinical and experimental data indicate a beneficial effect of estrogens on energy and glucose homeostasis associated with improved insulin sensitivity and positive effects on insulin secretion. The aim of the study was to investigate the impact of estrogens on proglucagon-producing cells, pancreatic α cells, and enteroendocrine L cells. The consequences of sexual hormone deprivation were evalu...
متن کاملModulation of Oxidative Stress by 17 β-Estradiol and Genistein in Human Hepatic Cell Lines In Vitro.
BACKGROUND/AIMS estrogens and phytoestrogens exert hepatoprotection through mechanisms not clearly examined yet. Here, we investigated the protective effects exerted by 17β-estradiol and genistein against oxidative stress in hepatocytes and hepatic stellate cells (HSCs) and the involvement of specific receptors and the intracellular signalling. METHODS Huh7.5 and LX-2, alone or in co-culture ...
متن کامل17-β-estradiol up-regulates apolipoprotein genes expression during osteoblast differentiation in vitro.
Apolipoproteins are of great physiological importance and are associated with different diseases. Many independent studies of patterns of gene expression during osteoblast differentiation have been described, and some apolipoproteins have been induced during this process. 17-β-estradiol (E2) may enhance osteoblast physiological function. However, no studies have indicated whether E2 can modulat...
متن کاملChronic estradiol - 17 β exposure increases superoxide production in the
1 Women are exposed to estrogen in several forms such as oral contraceptive pills and 2 hormone replacement therapy. Although estrogen was believed to be cardioprotective, 3 lately, its beneficial effects are being questioned. Recent studies indicate that oxidative 4 stress in the rostral ventrolateral medulla (RVLM) may play a role in the development of 5 hypertension. Therefore, we hypothesiz...
