Differential Expression of NADPH Oxidases Depends on Skeletal Muscle Fiber Type in Rats

Figure 1

Basal levels of oxygen (O2) consumption and citrate synthase activity in slow- and fast-twitch oxidative and glycolytic skeletal muscle fibers of rats. (a) Maximal coupled O2 consumption after pyruvate, malate, and succinate (PMS) addition and proton leak and O2 consumption related to ATP synthesis and (b) citrate synthase activity. Data were obtained with 10 animals from at least two independent experiments and are shown as mean ± SEM. ; .
