muscle
N
• despite mitochondrial defects, mice exhibit normal muscle strength and performance (J:104378)
• despite mitochondrial defects, mice exhibit normal muscle strength and performance (J:104378)
• at 18 months, muscle fibers exhibit an increase in the number and size of mitochondria compared to in wild-type mice (J:104378)
• severely affected muscle fibers exhibit large mitochondria with concentric cristae and electron-dense inclusions unlike in wild-type mice (J:104378)
