关键词: Curcumin Hyperuricemia XOD NLRP3 inflammasome

摘要:
Current evidences suggest that hyperuricemia is closely related to the overproduction or underexcretion of uric acid (UA). Curcumin (CUR), a natural polyphenol component extracted from the rhizome of Curcuma longa, has been reported to treat various symptoms such inflammation disease, seems to be efficacious in hyperuricemia. In this study, we aimed to investigate the effect of CUR on hyperuricemia and kidney inflammation in hyperuricemic mice. Administration with CUR (20 or 40 mg/kg) or allopurinol (ALL, 5 mg/kg) was given to mice orally one hour later after the injection of potassium oxonate (PO) (300 mg/kg, i.p.) for 14 days. CUR administration decreased the levels of uric acid (UA), creatinine (CRE) and blood urea nitrogen (BUN) in serum. Meanwhile, treatment with CUR effectively inhibited serum and liver xanthine oxidase (XOD) levels, and further renewed normal antioxidant enzymes activities (SOD, GSH-Px), reduced MDA accumulation in serum. Further studies showed that CUR decreased inflammatory cytokines productions (IL-1 beta, IL-18) in serum, as well as inhibited PO-induced the activation of NLRP3 inflammasome signaling in the kidney. In conclusion, the study revealed that CUR exhibited anti-hyperuricemic and anti-inflammatory effects through suppressing NLRP3 inflammasome activation in kidney and provided the evidence for treating hyperuricemia and associated renal inflammation.
