levels, and MDA levels and decreased GSH levels, suggesting that the HG condition induced ferroptosis. PD treatment inhibited ferroptosis in HG-induced cells, downregulated ACSL4 and TFR1 expression, and upregulated FTH-1 and SLC7A11 expression. PD reversed the effects of HG condition on cell death. Moreover, GPX4 expression was downregulated in HG-stimulated cells. Furthermore, we substantiated that PD suppressed ferroptosis by modulating GPX4 expression. In conclusion, PD inhibited ferroptosis in HG-induced HK-2 cells by upregulating GPX4 expression, suggesting that PD may be an effective drug for the clinical treatment of DN.
