We further treated the cells with CHIR99021, an activator of the Wnt signaling pathway. The results showed that CHIR99021 activated the GSK3β/β-catenin signaling pathway and reversed the PFOA-induced ...

Conclusion: Taken together, our results indicated that DSI could protect against ferroptosis to attenuate renal fibrosis by activating the SIRT1/GPX4 pathway. It is expected to be a potential agent to ...
