Abstract
Doxorubicin (DXR) is one of the most important chemotherapeutic agent. However, nephrotoxicity reduces its clinical utility in humans. The aim of the study was to investigate protective effects of curcumin (CMN) against DXR-induced nephrotoxicity. Rats were subjected to oral treatment of CMN (100 and 200 mg/kg body weight) for 7 days. Nephrotoxicity was induced by single intra peritoneal injection of DXR (40 mg/kg body weight) on the fifth day and then the experiment was terminated on the eighth day. Nephroprotective effects of CMN were associated with decrease in serum toxicity markers and increase in antioxidant enzyme activities. CMN was able to reduced the levels of inflammatory markers such as TNF-α, NF-κB, IL-1β, iNOS and COX-2 in the rats. It also reduced the expressions of apoptotic marker including caspase-3, and oxidative DNA damage marker including 8-OHdG. Collectively, these findings indicated that CMN protect against DXR-induced nephrotoxicity.
