Treatment of PC12 cells and PD mouse models with ferrostatin-1 or DADLE remarkably reduced the accumulation of MDA and 4-HNE (Figures 5(a) and 6(a)), decreased the protein expressions of GPX4 and SLC7a11 (Figures 5(b) and 6(b)), and restored the mitochondrial membrane potential (Figure 5(c), Supplementary Figure S3A). This evidence concerns the gene SLC7A11 and Parkinson disease.
