Interestingly, several mitochondrial proteins involved in AD, PD and Huntington's disease were only significantly changed in the chronic low dose group, such as ATP synthase subunit epsilon (P56382), Cytochrome c oxidase subunit 7C (P17665), Cytochrome c oxidase subunit 6A1 (P43024). The gene discussed is COX7C; the disease is Parkinson disease.
