Effect of RC on oxidative stress in skeletal muscle atrophy. Muscle antioxidant activities, including superoxide dismutase (SOD, (A), catalase (B), and glutathione content (C). Enzyme activity (D) and isoform mRNA expression (E) of NADPH oxidase (NOX) were measured. Western blot analysis of Nrf2 and its downstream targets were performed (F). Malondialdehyde (MDA) for lipid peroxidation (G) and 8-hydroxy-2ʹ-deoxyguanosine (8-OHdG) for DNA damage (H) were measured. Data are shown as mean values ±SEM. (I) The potential mechanism of RC and rutin for the improvement of muscle atrophy. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001 versus DEX.
