ResultsThe results showed that the induction of NAFLD reduced expression of Mfn1 (P=0.001) and Mfn2 (P=0.001) compared to control-normal.Also, in SUPNAF and RSUPNAF groups, Mfn1 (P=0.002 and P=0.017 respectively) and Mfn2 (P=0.000 and P=0.000 respectively) increased significantly compared to the NAFLD group.Conclusion The combination of aerobic exercise and resveratrol may be due to changes in expression of mitochondrial fusion, modifying indexes apoptosis induced by oxidative stress in NAFLD patients.
