Metformin is accepted as a first-line drug for the therapy of type 2 diabetes (T2D), while its mechanism is still controversial. In this study, by taking advantage of mouse model of high-fat-diet (HFD)-induced obesity and primary mouse hepatocytes (PMHCs) as well as human hepatocyte L02 cell line, we aimed to investigate the involvement of SIRTs during the application of metformin for the therapy of T2D. Our data evidenced that during HFD-induced obesity, there was elevation of nucleus protein acetylation. Analysis of liver tissue showed that among all SIRT members, SIRT6 expression was significantly downregulated during HFD feeding, which was sustained to regular level with metformin administration...
