Chronic arsenic exposure has been associated with various toxic effects, especially to the organs of liver and kidney. As a plant polyphenol, curcumin is the most vital bioactive ingredient of turmeric and has a wide range of pharmacological activities. In the present study, we investigated the potential roles of curcumin against arsenic‐induced liver and kidney dysfunctions in mice. Curcumin treatment (200 mg/kg) not only decreased the deposition of arsenic in liver and kidney, but also relieved the hepatic and nephritic biochemical indexes (Glutamic oxaloacetic transaminase [AST], Alanine aminotransferase [ALT], albumin, and creatinine) altered by arsenic at doses of 10 and 25 mg/L via drinking water. What's more, curcumin exerted influences on the activities of myeloperoxidase and on the secretion of inflammatory cytokines in liver and kidney tissues. In addition, the levels of mitogen‐activated protein kinases (MAPKs) and nuclear factor kappa B (NF‐κB) phosphorylation were declining while NRF2‐signaling targets were increasing in mice liver and kidney by curcumin administration. In conclusion, our results here suggest that curcumin could exert both anti‐inflammatory and antioxidant functions on arsenic‐induced hepatic and kidney injury by inhibiting MAPKs/NF‐κB and activating Nrf2 pathways cooperatively.
