Parkinson's disease (PD) is a neurodegenerative disorder characterized by degeneration of dopaminergic neurons associated with dysregulation of iron homeostasis in the brain. Ferroptosis is an iron-dependent cell death process that serves as a significant regulatory mechanism in PD. However, its underlying mechanisms are not yet fully understood. By performing RNA sequencing analysis, we found that the main iron storage protein ferritin heavy chain 1 (FTH1) is differentially expressed in the rat 6-hydroyxdopamine (6-OHDA) model of PD compared with control rats. Our present work demonstrates that FTH1 is involved in iron accumulation and the ferroptosis pathway in this model. Knockdown of FTH1 in PC-12 cells significantly inhibited cell viability and caused mitochondrial dysfunction. Moreover, FTH1 was found to be involved in ferritinophagy, a selective form of autophagy involving the degradation of ferritin by ferroptosis. Overexpression of FTH1 in PC-12 cells impaired ferritinophagy and downregulated microtubule-associated protein light chain 3 and nuclear receptor coactivator 4 expression, ultimately suppressing cell death induced by ferroptosis. Consistent with these findings, the ferritinophagy inhibitors chloroquine and bafilomycin A1 inhibited ferritin degradation and ferroptosis in 6-OHDA-treated PC-12 cells. This entire process was mediated by the cyclic regulation of FTH1 and ferritinophagy. Taken together, these results suggest that FTH1 links ferritinophagy and ferroptosis in the 6-OHDA model of PD, and provide a new perspective and potential for a pharmacological target in this disease.
