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.
