PG - 1984-91 AB - AIMS: MicroRNAs play important roles in energy metabolism, insulin synthesis, insulin transport and the development of diabetes. This study aims to investigate the expression and effect of microRNA-130a in Uygur patients with type 2 diabetes mellitus (T2DM). MATERIALS AND METHODS: Peripheral blood and omental adipose tissues were collected from individuals with normal glucose tolerance and patients with T2DM. The microRNA expression profile of peripheral blood was established by microarray analysis. The differentially expressed microRNAs and possible target genes were identified by bioinformatics analysis. MicroRNA-130a mimics and inhibitors were transfected into 3T3-L1 preadipocytes. RESULTS: Our results showed that microRNA-130a expression level was significantly decreased in peripheral blood and omental adipose tissues of T2DM patients (P < 0.01). Peroxisome proliferator-activated receptors gamma (PPARgamma) were predicted as target genes of microRNA-130a. This prediction was verified by the results that PPARgamma mRNA expression in omental adipose tissues of T2DM patients were significantly increased (P < 0.01). The glucose consumption level after microRNA-130a transfection was significantly decreased (P < 0.05). And, microRNA-130a mimics inhibited PPARgamma expression at both mRNA and protein level, further suggesting that PPARgamma is a target gene of microRNA-130a. Additionally, adiponectin, lipoprotein lipase, CCAAT enhancer binding protein alpha, and the downstream genes of PPARgamma, were significantly decreased after microRNA-130a mimics transfection. CONCLUSIONS: In conclusion, microRNA-130a is decreased in Uygur patients with T2DM and it may play a role in T2DM through targeting PPARgamma.
