The results revealed that both RSV doses (20 and 30 mg/kg/day) as well as Fer‐1 treatment significantly enhanced the expression levels of GPX4 and FTH1 compared to the PD model group (p < 0.05, p < 0.05; Figure 6K–M), suggesting that RSV may protect against ferroptosis through this axis. This evidence concerns the gene FTH1 and Parkinson disease.
