Abstract

摘要： 肥胖已经成为全球面临的一个严重公共健康问题。肥胖是机体能量失衡导致脂肪过度积聚为重要特征的一种代谢异常,主要表现为脂肪细胞数量异常增加和体积异常增大,因此深入理解脂肪细胞分化机制对肥胖防治具有重要意义。microRNA(miRNA)是近年来在真核生物体内发现的、一类长度约22nt的内源性非编码单链小RNA,通过与靶标mRNA不完全互补配对,发挥降解靶mRNA或抑制靶mRNA翻译的作用。miRNA几乎参与所有生命活动的调节和大多数疾病的发病过程,包括脂肪细胞分化、肥胖发生发展。本文主要综述miRNA在脂肪细胞分化、肥胖研究领域取得的成果,并分析该领域的现状、不足及前景。
