MitoQ ameliorated alcohol-induced liver injury and lipid metabolism alterations. (A) Levels of plasma ALT and AST in each group. (B) Liver histopathological changes in each group shown by H&E staining (arrows: lipid droplets, arrowheads: inflammatory cells) Scale bar: 50 µm. (C) Oil red O staining of neutral lipids. Scale bar: 20 µm. (D) Levels of proteins involved in lipid metabolism. (E) Liver TG content. (F) Liver FFA concentration. (G) Plasma TG content. (H) Plasma FFA concentration. Proteins levels were quantitated by NIH image J. All values are denoted as means ± SD. * P < 0.05 vs PF, ** P < 0.01 vs PF, # P<0.05 vs. AF, ## P<0.01 vs. AF, §, P<0.05 vs. PF/MitoQ.
