Abstract Title:
Neuroprotective effects of mitochondria-targeted curcumin against rotenone-induced oxidative damage in cerebellum of mice.
Abstract:
The present study investigated the protective effect of curcumin and mitochondrial-targeted curcumin (MTC) in rotenone-induced cerebellar toxicity in mice. Treatment of rotenone in mice significantly shortened the stride length for both forelimb and hind-limb and increased fore-paws and hind-limb base width. Co-treatment of curcumin and MTC with rotenone improved the walking pattern. A significant increase in lipid peroxidation, nitric oxide and decreased activity of AChE, reduced glutathione, superoxide dismutase and catalase were observed in rotenone-treated mice while co-treatment of curcumin and MTC with rotenone significantly increased AChE activity and protected against rotenone-induced oxidative damage. Rotenone exposed mice showed irregular, damaged Purkinje cells and perineuronal vacuolation while co-treatment of curcumin and MTC with rotenone protected against rotenone-induced cellular damage in these cells. The result exhibits that both curcumin and MTC showed protective effects against rotenone-induced cerebellar toxicity in mice and MTC is more effective than curcumin.
