Fig. (4) Myocardial tissue homogenates, and Western blot experiments were performed using the β-actin was normalized the results. Western blot demonstrating phosphorylation and total protein levels of (ERK1/2), Vit D treated mice displayed reduction in the levels of p-ERK1/2. Densities (Arbitrary Units, AU). Data are expressed as mean ± standard error; *P <0.05 versus corresponding sham; **P <0.05 versus I/R and vehicle.
