ABSTRACT
AIM:
To study the protective effects of crocetin on the doxorubicin-induced damage in rats with myocardial mitochondria.METHODS:
Rats were given intraperitoneal injection of doxorubicin to induce cardiotoxicity. After continuous oral administration of crocetin, the rats were sacrificed, and myocardial mitochondria were isolated. The mitochondrial membrane potential (MMP), O~-_2. production, the activity of respiratory chain complex IV and glutathione peroxidase (GSH-PX), and DNA fragmentation were determined. The expression level of COII gene was determined through RT-PCR.RESULTS:
Crocetin increased the activity of respiratory chain complex IV and GSH-PX, MMP and the expression level of COII and decreased DNA fragmentation and superoxide anion radical O~-_2. production in rats with myocardial mitochondria.CONCLUSION:
Crocetin may decrease the damage in rat myocardial mitochondria induced by doxorubicin.
