Maternal high-fat diet feeding induces hepatic mef2a hypermethylation in offspring. A CpG sites measured in Mef2a promoter. B DNA methylation levels of different CpG sites in Mef2a promoter. C Average DNA methylation level in Mef2a promoter. D Correlation between Mef2a methylation level and Mef2a mRNA expression. E Correlation between Mef2a methylation level and MEF2A protein expression. F mRNA expression of Mef2a in 5-AZA-treated HepG2 cells. G Representative immunoblot images for MEF2A in 5-AZA-treated HepG2 cells. H Immunoblot analysis of MEF2A in 5-AZA-treated HepG2cells. I Relative luciferase activity of methylated or unmethylated plasmids in H9C2 cells. F1, the second generation (offspring); Ctrl, standard diet; HFD, high-fat diet; MEF2A, myocyte enhancer factor 2A; 5-AZA, 5-azacitidine. Data presented as the mean ± SEM. *P < 0.05, ***P < 0.001 versus F1-Ctrl group. n = 7–8 litters/group, one male offspring per litter. *P < 0.05, ***P < 0.001 versus Ctrl. n = 6–7 litters for F1-Ctrl group, n = 6–7 litters for F1-HFD group, one male offspring per litter
