Background & objectives: Dynamic disorders of mitochondria cause the pathogenesis of many diseases, such as type 2 diabetes. Therefore, the aim of this study was to investigate the interactive effect of aerobic exercises and atorvastatin consumption on the expression of MFN1/2 and DRP1 in hepatocytes of rat liver with type 2 diabetes. Methods: In this experimental study, 25 male rats were divided into 5 equal groups: diabetes, healthy control, persistence+diabetes, atorvastatin+diabetes, persistence+atorvastatin+ diabetes. Type 2 diabetes was induced by streptozotocin (STZ) in mice. The training groups performed the running program on the treadmill for eight weeks. Atorvastatin and atorvastatin-exercise groups received atorvastatin (10 mg/kg) by gavage. 48 hours after the last training session, the rats were dissected; their liver tissue was removed and immediately frozen in liquid nitrogen solution at a temperature of minus 80 ° C to measure MFN1/2 and DRP1. One-way analysis of variance and Tukey post hoc test were used for statistical analysis at a significance level of p
