【摘要】 代谢性核受体是一组与代谢调节相关的配体激活核受体转录因子,主要包括脂质过氧化物体增殖物激活受体(PPARs)、肝X受体(LXRs)和法尼酯衍生物X受体(FXRs)3种。它们在胰岛素敏感性、脂肪生成、脂质代谢、能量代谢、血压调节、炎症、细胞生长和分化等过程中起着关键的调节作用,因而近年来倍受关注。越来越多的研究表明这3种核受体不仅与代谢综合征,包括胰岛素抵抗、糖耐量受损2、型糖尿病、肥胖、高脂血症、高血压和微白蛋白尿之间存在密切的关系,也在动脉粥样硬化的发生及发展中有重要的作用。本文就代谢性核受体的生物学活性和生理功能作一简述,并对其在代谢综合征发病机制中的作用进行重点讨论。更多还原

【Abstract】 Metabolic nuclear receptors consist of a group of nuclear hormone receptor transcription factors including peroxisome proliferator-activated receptors(PPARs),liver X-activated receptors(LXRs) and farnesoid X-activated receptors(FXRs).They have been identified and drawn enormous attention due to key roles in regulating adipogenesis,lipid metabolism,energy metabolism,insulin sensitivity,inflammation,blood pressure,cell growth and differentiation.Growing evidences support a causative relationship between these three metabolic nuclear receptors and the metabolic syndrome,which is characterized by insulin resistance,glucose intolerance or type II diabetes,obesity,dyslipidemia,hypertension,and microalbuminuria.These receptors have also been implicated in pathogenesis of atherosclerosis.Here we review the literature pertaining to the action and physiological role of metabolic nuclear receptors with particular emphasis on their pathogenic roles in the metabolic syndrome.更多还原
