摘要: 目的:利用尿酸诱导的小鼠肾小管上皮细胞(mouse tubular epithelial cells, mTECs)观察薯蓣皂苷及NF-κB P65抑制剂BAY11-7082对于尿酸导致的细胞炎症损伤的影响。方法:1.2 mol/L尿酸诱导mTECs细胞后,分别给予25 μmol/L、50 μmol/L和100 μmol/L薯蓣皂苷或者10 μmol/LBAY11-7082干预,利用Western Blot、免疫荧光染色和real-time PCR检测细胞中IκB-α、NF-κB P65、PP65、NLRP3、IL-1β、β-actin的表达。结果:Western Blot、免疫荧光染色和real-time PCR结果显示,薯蓣皂苷及BAY11-7082可下调尿酸诱导mTECs细胞中PP65/P65比值、NLRP3及IL-1β的表达(P<0.05),同时薯蓣皂苷上调IκB-α的表达(P<0.05)。 结论:薯蓣皂苷可通过抑制NF-κB信号通路减轻尿酸诱导的细胞炎性损伤。

Abstract: AIM: To observe the effect of Dioscin treatment on NF-κB signaling pathway and cellular inflammatory injury and explore its potential mechanism in uric acid-induced mouse tubular epithelial cells (mTECs).  METHODS: After 1.2 mol/L uric acid induced mTECs, Dioscin and NF-κB P65 inhibitor BAY11-7082 were given to intervene respectively. IκB-α, NF-κB P65, PP65, NLRP3, IL-1β and β-actin were detected by Western Blot, immunofluorescence staining and real-time PCR. RESULTS: Western Blot, immunofluorescence staining and real-time PCR analysis showed that expression levels of PP65, NLRP3 and IL-1β were significantly downregulated in the uric acid-induced mTECs with Dioscin and BAY11-7082 treatment. CONCLUSION: Dioscin attenuates uric acid-induced cellular inflammatory damage by suppression NF-κB signaling pathway.
