(A) (B) Effects of exercise and/or Epi on myocardial HSP-90, AKT, CAM1 and Cav-1 protein levels from water (W), exercise (Ex), epicatechin (Epi) and epicatechin plus exercise (Epi-Ex) groups. GAPDH was used as a loading. An antibody against total eNOS was used for the immunoprecipitation. (C) eNOS, p-Ser617, p-Ser1177 levels. Mean±SEM relative to W group (100%) values. *p < 0.05 vs. water; **significantly different from Ex or Epi, †significantly different vs. exercise only.
