چکیده
Objective(s): This study aims to explore the effect of mitoTEMPOL on histopathology, lipid droplet, and mitophagy gene expression of Wistar rat’s liver after injection of streptozotocin (STZ).Materials and Methods: Twenty male Wistar rats were divided into ۴ groups: Control (n=۵); ۱۰۰ mg/kg BW/day mitoTEMPOL orally (n=۵); ۵۰ mg/kg BW STZ intraperitoneal injection (n=۵); and mitoTEMPOL+STZ (n=۵). STZ was given a single dose, while mitoTEMPOL was given for ۵ weeks after ۱ week of STZ injection. Histopathological appearance, lipid droplets, mitophagy, and autophagy gene expression were examined after the mitoTEMPOL treatment. Results: We found metabolic zone shifting that might be correlated with the liver activity of fatty acid oxidation in the STZ group, a decrease of lipid droplets in mitoTEMPOL and mitoTEMPOL + STZ compared with Control and STZ groups were found in this study. We also found significant changes in PINK۱, Parkin, BNIP۳, Mfn۱, and LC۳ gene expression, but no difference in Opa۱, Fis۱, Drp۱, and p۶۲ gene expression, suggesting a change of mitochondrial fusion rather than mitochondrial fission correlated with mitophagy.Conclusion: All this concluded that mitoTEMPOL could act as a modulator of mitophagy and metabolic function of the liver, thus amplifying its crucial role in preventing mitochondrial damage in the liver in the early onset of diabetes mellitus.کلیدواژه ها
