Lipid peroxidation, superoxide dismutase and UCP3 content in muscle mitochondria from adult and old rats. A: Lipid peroxidation in intermyofibrillar and subsarcolemmal skeletal muscle mitochondria from adult and old rats. B: Superoxide dismutase specific activity in intermyofibrillar and subsarcolemmal skeletal muscle mitochondria from adult and old rats. C: Quantification of UCP3 (with representative western blots; odd numbers = adult rats, even numbers = old rats) and UCP3 content ratio in intermyofibrillar and subsarcolemmal skeletal muscle mitochondria from adult and old rats. Values are the means ± SEM of eight different rats. IMF = intermyofibrillar; SS = subsarcolemmal; TBARS = thiobarbituric acid reactive substances. *P < 0.05 compared to adult rats; #P < 0.05 compared to intermyofibrillar mitochondria (non parametric two-way ANOVA).
