摘要

Sodium fluoride-induced ocular damage constitutes a significant public health concern globally; however, the precise molecular mechanisms underlying this issue remain obscure. This study aims to investigate the effects of sodium fluoride on myopia and to offer novel theoretical foundations for future strategies in myopia prevention and control. The experimental data showed that sodium fluoride could promote myopia progression, and through bioinformatics analysis, we found that sodium fluoride could affect the ferroptosis pathway. Western blotting and redox kit assays further confirmed that sodium fluoride activates the ferroptosis pathway. We also demonstrated that PIEZO1 plays a crucial role in sodium fluoride-induced myopia, and that the PIEZO1 inhibitor (GsMTx4) can inhibit the ferroptosis pathway. Subsequently, we identified PIEZO1 as a potential target of baicalin, which inhibited PIEZO1 expression in vivo and in vitro, as confirmed by molecular docking modeling and CETSA assays. Finally, we found that baicalin inhibited sodium fluoride-induced myopia via PIEZO1. Taken together, our findings indicate that sodium fluoride can promote myopia progression by activating the ferroptosis pathway through PIEZO1, and that targeting PIEZO1 expression can delay myopia progression, which may provide a new drug target for myopia treatment in the future.
