miRNA-21在糖尿病肾脏病的作用机制及中药干预新进展

New progress of mechanism of action of miRNA-21 in diabetic kidney disease and Chinese medicine intervention

糖尿病肾脏病是糖尿病的并发症之一,可进展至终末期肾脏病。近年研究发现,miRNA-21可通过调控转化生长因子-β1(TGF-β1)/Smads、磷脂酰肌醇3-激酶(PI3K)/蛋白激酶B(AKT)、Wnt/β-连环蛋白等信号通路影响糖尿病肾脏病的进展。中药对miRNA-21表达具有调节作用,可以靶向miRNA-21调控TGF-β1/Smads、磷酸酶张力蛋白同源物/PI3K/AKT/哺乳动物雷帕霉素靶蛋白、过氧化物酶体增殖物激活受体等信号转导,引发信号级联反应,干预纤维化、炎症、氧化应激、自噬等病理过程。就miRNA-21在糖尿病肾脏病中的作用机制及中药对其的干预作用进行综述。

Diabetic kidney disease is one of the complications of diabetes,which can progress to end-stage renal disease.In recent years,it has been found that miRNAs have become a research hotspot,with miRNA-21 regulating transforming growth factorβ1(TGF-β1)/Smads,phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT),Wnt/β-catenin and other signaling pathways to promote the progress of diabetic kidney disease.Studies have showed that traditional Chinese medicine has a regulatory effect on the expression of miRNA-21 and can target miRNA-21 to regulate TGF-β1/Smads,phosphatase and tensin homolog/PI3K/AKT/mammalian target of rapamycin(mTOR),peroxisome proliferator activated receptors and other signal transduction pathways to trigger signal cascade reactions,which intervene in pathological processes such as fibrosis,inflammation,oxidative stress and autophagy.In this article,the role of miRNA-21 in diabetic kidney disease and the intervention of traditional Chinese medicine were summarized,in order to provide some reference for the treatment of diabetic kidney disease and the development of new drugs.
