FIGURE 3.
Mitochondria from 2-week-old, mdx male muscles display altered size, cristae numbers per area of mitochondria, and enzymatic activity. (A) Mitochondrial DNA copy number in quadriceps muscle (N = 5). (B) Immunoblot images from quadriceps muscle (N = 6–8, showing N = 3). (C) HE stain of gastrocnemius muscle. Scale bar = 0.1 mm. (D) Electron micrograph images of the soleus muscle with quantified mitochondrial area and cristae numbers per area of mitochondria shown right. Black arrows indicate aberrant mitochondria. (E) Complex IV activity in quadriceps muscle (N = 5). Data presented as Mean ± SEM. (F) Mitochondrial respirometry analysis in frozen quadriceps muscle (N = 6–8). *P < 0.05.
