Exercise training increases expression of the endothelial marker platelet endothelial cell adhesion molecule-1 (PECAM-1) in human skeletal muscle. (A and B) Representative immunoblots of PECAM-1 protein expression in the vastus lateralis muscle from young men (A, n = 16) or senior subjects (B, n = 14) before and after endurance training. C, Densitometric analysis of PECAM-1 protein expression is represented and β-actin was used as a loading control. Data are presented as means ± SEM. The effect of exercise training or age was considered statistically significant when P ≤ 0.05 after two-way ANOVA analysis and Bonferroni posttest.
