Abstract:

AIM: To investigate the effect and mechanism of resveratrol on the expression of high mobility group box 1 in rats with hepatic ischemia-reperfusion injury. METHODS: Thirty healthy male Sprague-Dawley (SD) rats were randomly divided into three groups: sham control (SC) group, hepatic ischemia reperfusion injury (HIR) group and resveratrol (Res) group. The blood samples and liver tissue samples were collected. The pathological changes of the liver were observed. Serum ALT, AST and AKP activity were detected as indicators of liver function damage and the content of TNF-α and IL-6 in serum were detected by ELISA. The expressions of HMGBl and TLR4 protein and mRNA were determined by Western Blot and RT-PCR.RESULTS:Compared with the HIR group, the pathological injury of the liver was significantly improved and the concentrations of serum AST, ALT and AKP were significantly lower in Res group (P<0.01); meanwhile, the expression of HMGB1 and TLR4 protein and mRNA of hepatic tissue were decreased, serum inflammatory factors IL-6 and TNF-α were also significantly decreased (P<0.01). CONCLUSION: Resveratrol shows significant protective effect on hepatic ischemia reperfusion injury in rat. This may be related with inhibiting the HMGBl-TLR4 signaling pathway and alleviating the inflammatory response.
