Resveratrol restored Slc2a4 mRNA and GLUT4 protein expression in skeletal of T2DM mice. Slc2a4 mRNA (A); GLUT4 protein (B), and nuclear SIRT1 protein (C) were analysed in gastrocnemius skeletal muscle of non-diabetic (ND), type 2 diabetic (T2DM), and resveratrol-treated type 2 diabetic (T2DMR) mice. In (A), Slc2a4 mRNA was normalized by Atp5b mRNA (ATP synthase, H+ transporting, mitochondrial F1 complex, beta polypeptide); In (B,C), representative images of GLUT4 and SIRT1 proteins and respective Ponceau-stained membranes are shown. Data are expressed as mean ± SEM of 5–7 animals, and were analysed by one-way ANOVA with the Newman-Keuls post-test. * p < 0.05 and *** p < 0.001 vs. ND; # p < 0.05, and ## p < 0.01 vs. T2DM.
