WebOct 4, 2024 · System Xc- and glutathione peroxidase 4 (GPX4) are widely known to be required for ferroptosis prevention. For example, the inhibition of system Xc- can block cystine/glutamate transport, leading to cellular glutathione depletion. Glutathione is a major antioxidant and can be utilized by GPX4 to reduce lipid peroxidation. WebApr 6, 2024 · And the phosphorylation of JNK and c-Jun played an essential role in the underlying molecular mechanism. Wen et al. ... Moreover, PD suppressed ferroptosis in high glucose-induced cells by regulating GPX4 expression, suggesting that PD may help treat diabetic nephropathy. However, ...
