Estrogen Signals Through Peroxisome Proliferator-Activated Receptor−γ Coactivator 1α to Reduce Oxidative Damage Associated With Diet-Induced Fatty Liver Disease

Inefficient fatty acid oxidation in mitochondria and increased oxidative damage are features of non-alcoholic fatty liver disease (NAFLD). In rodent models and patients with NAFLD, hepatic expression of peroxisome proliferator-activated receptor-γ (PPARG) coactivator 1α (PPARGC1A or PGC1A) is inversely correlated with liver fat and disease severity. A common polymorphism in this gene (rs8192678, encoding Gly482Ser) has been associated with...
