[Retracted] Treadmill Training Increases SIRT-1 and PGC-1α Protein Levels and AMPK Phosphorylation in Quadriceps of Middle-Aged Rats in an Intensity-Dependent Manner

Figure 3

Effects of exercise protocols performed in different intensities on the CPT1, Cyt-c, citrate synthase, and SDH protein levels and SDH and citrate synthase activity in the quadriceps of young and middle-aged rats. Protein levels of CPT1 (a), Cyt-c (b), SDH (c), and citrate synthase (e). Upper panels show representative blots of these proteins. The results of scanning densitometry are expressed as arbitrary units. The activities of succinate dehydrogenase (d) and citrate synthase (f) are expressed as nmol/min/mg of protein. Bars represent means ± SEM of six rats. ^∗𝑃<0.05 versus young NE rats, ^#𝑃<0.05 versus middle-aged NE rats, ^$𝑃<0.05 versus young rats at 0.8 km/h, and ^&𝑃<0.05 versus middle-aged rats at 0.8km/h.
