Doxorubicin (DXR) is a highly effective drug for chemotherapy. However, cardiotoxicity reduces its clinical utility in humans. The present study aimed to assess the ameliorative effect of curcumin against DXR-induced cardiotoxicity in rats. Rats were subjected to oral treatment of curcumin (100 and 200 mg/kg body weight) for 7 days. Cardiotoxicity was induced by single intraperitoneal injection of DXR (40 mg/kg body weight) on the 5th day and the rats sacrificed on 8th day. Curcumin ameliorated DXR-induced lipid peroxidation, glutathione depletion, decrease in antioxidant (superoxide dismutase,catalase, and glutathione peroxidase) enzyme activities, and cardiac toxicity markers (CK-MB, LDH, and cTn-I). Curcumin also attenuated activities of Caspase-3, cyclooxygenase-2, inducible nitric oxide synthase, and levels of nuclear factor kappa-B, tumor necrosis factor-α, and interleukin-1β, and cardiac tissue damages that were induced by DXR. Moreover, curcumin decreased the expression of 8-OHdG and 3,3'-dityrosine. This study demonstrated that curcumin has a multi-cardioprotective effect due to its antioxidant, anti-inflammatory, and antiapoptotic properties.
