Figure 2. Increased ROS production and altered mitochondrial regulators of SM in mice during aging. (A) Representative ROS fluorescence staining of Ga muscles and quantification, Scale bar: 100 μm, n=3; (B) mRNA levels of mitochondrial biogenesis, mitochondrial dynamics and mitophagy/autophagy-related markers, n=7; (C) Representative Western blots and (D) quantification of Mfn1, Drp1, Pink1, DJ-1, LC3II/I, p62 and Gapdh (loading control), n=3. *p<0.05, **p<0.01, ***p<0.001 vs. 6m group; #p<0.05, ##p<0.01 vs. 15m group.
