MicroRNA-770-5p is involved in the development of diabetic nephropathy through regulating podocyte apoptosis by targeting TP53 regulated inhibitor of apoptosis 1. Eur Rev Med Pharmacol Sci. 2019 Feb;23(3):1248-1256 Authors: Zhang SZ, Qiu XJ, Dong SS, Zhou LN, Zhu Y, Wang MD, Jin LW Abstract OBJECTIVE: Diabetic nephropathy (DN) is a major diabetic micro-vascular complication, and podocyte apoptosis induced by high glucose (HG) is a typical early feature of DN. Studies have shown that microRNAs (miRNAs) play a crucial role in the pathogenesis of DN. The purpose of the current study was to explore the role and molecular mechanism of miR-770-5p in podocyte apoptosis in DN. PATIENTS AND MATERIALS AND METHODS: In vitro podocyte model of DN was conducted by treatment conditionally immortalized mouse podocytes with HG (30 mM D-glucose). The level of miR-770-5p in podocytes was detected using quantitative real-time PCR (qRT-PCR), and protein levels were measured using Western blot assay in our current study. The relationship between miR-770-5p and TP53 regulated inhibitor of apoptosis 1 (TRIAP1) was revealed by TargetScan and dual luciferase reporter assay. Cell proliferation ability and cell apoptosis were determined by using cell counting kit-8 (CCK-8) assay and flow cytometer (FCM), respectively. RESULTS: We found that miR-770-5p was significantly upregulated in podocytes under HG condition. TRIAP1 was a target gene of m...
