Muscle protein oxidation in untrained and trained animals. Western blotting analysis to detect carbonylated proteins (MW: 37 kDa). Representative experiments are shown. For the densitometric analysis of the results values are shown as mean (±SD) of a WT untrained (n = 6), WT trained (n = 8), PGC-1α KO untrained (n = 7), and PGC-1α KO-trained animals (n = 6); b young untrained (n = 6), young trained (n = 6), aged untrained (n = 6), and aged-trained animals (n = 6)
