2-Fold reduction of Mclk1 expression significantly reduces the levels of systemic oxidative damage observed in Sod2+/− mice. Mclk1 heterozygosity reduced the levels of systemic oxidative stress as revealed by an increased mitochondrial aconitase activity (A) as well as by a reduction in the amounts of cytosolic lipid peroxidation (B), cytosolic carbonyls (C), and plasmatic 8-OHdG (D) observed in 15-month-old Sod2+/− Mclk1+/− mutants. Each point or bar in the graphs represents the mean ± S.E. of 8–10 animals. The statistical significance of the differences between 3- and 15-month-old Sod2+/− Mclk1+/− animals (A) or between Sod2+/− and Sod2+/− Mclk1+/− animals (B–D) were shown on the respective graphs; p < 0.05.
