A, quantification of the mRNA content of several proteins involved in the mitochondrial biogenesis program in skeletal muscle homogenates from Park2−/− and Park2+/+ mice. B–G, quantification of the content of PGC‐1a (n = 4 per group), PGC‐1b (B) (n = 4 per group), TOMM70 (C) (n = 4 per group), VDAC (D) (n = 4 per group), COX I (E) (n = 7 or 8 per group), COX IV (F) (n = 4 per group) and HSP60 (G) (n = 4 per group) in skeletal muscle of Park2−/− and Park2+/+ mice by western blotting (n = 4 per group). *
