BACKGROUND/AIMS Liver X receptors (LXRα and LXRβ) are ligand-activated transcription factors that regulate expression of genes involved in lipid and cholesterol metabolism. LXR expression has been identified in human and rodent cardiac tissue, however, its role in this tissue remains unclear. The aim of this study was to investigate effects of in vivo LXR activation on lipid metabolism in the r...
مقدمه: ژن lxrβ که نقش اساسی در سوخت و ساز قند و چربی برعهده دارد، در یک ناحیه ی کروموزومی حساس به چاقی قرار گرفته و تغییرات ژنتیکی در آن می تواند با بروز چاقی مرتبط باشد. هدف پژوهش حاضر، بررسی ارتباط واریانت 17373080rs ژن یاد شده با بروز چاقی و فنوتیپ های مرتبط با آن بود. مواد و روش ها: در مطالعه ی مورد ـ شاهدی حاضر تعداد 435 نفر متشکل از 160 نفر چاق، 201 نفر اضافه وزن و 74 نفر با وزن طبیعی به ...
OBJECTIVE Pharmacological LXR activation has anti-atherosclerotic actions in animal models. Part of these beneficial effects may be explained by accelerated reverse cholesterol transport since both plasma high density lipoprotein (HDL) cholesterol and fecal neutral sterol secretion are higher upon LXR activation. Mechanisms underlying these LXR-mediated effects have not been fully elucidated. ...
Liver X receptors (LXRα/β) and carbohydrate response element-binding proteins (ChREBPα/β) are key players in the transcriptional control of hepatic de novo lipogenesis. LXRα/β double knockout (LXRα-/-/β-/-) mice have reduced feeding-induced nuclear O-linked N-acetylglucosamine (O-GlcNAc) signaling, ChREBPα activity, and lipogenic gene expression in livers, suggesting important roles for LXRs in...
OBJECTIVE Liver X receptors (LXRα, LXRβ) are master regulators of cholesterol homeostasis. In the endothelium, perturbations of cell cholesterol have an impact on fundamental processes. We, therefore, assessed the effects of LXR activation on endothelial functions related to angiogenesis in vitro and in vivo. METHODS AND RESULTS LXR agonists (T0901317, GW3965) blunted migration, tubulogenesis...
