Introduction: Insulin-like growth factor-1 (IGF-1) promotes survival and inhibits cardiac autophagy disruption. Methods: Male Wistar rats were treated with IGF-1 (50 μg/kg), and 24 h after injection hearts were excised. The level of interaction between Beclin-1 and the α1 subunit of sodium/potassium-adenosine triphosphates (Na+/K+-ATPase), and phosphorylated forms of IGF-1 receptor/insulin receptor (IGF-1R/IR), forkhead box protein O1 (FOXO1) and AMP-activated protein kinase (AMPK) were measured. Results: The results indicate that IGF-1 decreased Beclin-1’s association with Na+/K+-ATPase (p < 0.05), increased IGF-1R/IR and FOXO1 phosphorylation (p < 0.05), and decreased AMPK phosphorylation (p < 0.01) in rats’ hearts. Conclusions: The new IGF-1 therapy may control autosis and minimize cardiomyocyte mortality.
