盐皮质激素受体过度活化诱导肥胖脂肪组织重塑
【摘要】 肥胖是在一定的遗传背景的基础上,由多种环境因素长期作用引起的一种慢性疾病。其中,盐皮质激素受体(MR)过度活化作为一种环境因素,在肥胖脂肪组织重塑中具有重要作用。肥胖状态下,脂肪组织MR的过度活化可通过促进脂肪组织分化和脂肪生成以及诱导脂肪组织炎症反应、氧化应激、脂肪因子分泌紊乱和胰岛素抵抗等机制诱导肥胖脂肪组织重塑,而肥胖脂肪组织重塑是肥胖相关代谢性疾病的决定性因素。而且,使用MR拮抗剂可在一定程度上逆转由于MR过度活化所引起的肥胖脂肪组织重塑。因此,明确MR过度活化在肥胖脂肪组织重塑中的作用及其机制具有重要意义。【关键词】 肥胖;盐皮质激素受体;盐皮质激素受体拮抗剂

【Abstract】 Obesity is a chronic disease caused by the long-term interaction of multiple environmental factors on a specific genetic background. Among these factors, the overactivation of mineralocorticoid receptors (MR) plays a significant role in adipose tissue remodeling in obesity. In the obese state, the MR overactivation in adipose tissue can promote adipose tissue differentiation and adipogenesis ......
