AKT1 and myocardial infarction: Western blotting analysis revealed that the levels of phosphorylation of Akt and ERK were rescued by nesfatin‐1 to a significant extent in the heart of mouse with MI/R injury, but the basal levels of Akt and ERK were not affected obviously (Figure 3A), therefore describing that the activation of Akt/ERK pathway is recovered by nesfatin‐1.
