Elevated serum mitochondrial DNA in females and lack of altered platelet mitochondrial methylation in patients with Parkinson´s disease

Abstract excerpt

Purpose: Mitochondrial dysfunction has long been considered in the pathogenesis of Parkinson's disease (PD). This is evident from the presence of mitochondrial DNA deletions in substantia nigra neurons and respiratory chain abnormalities in the skeletal muscle of PD patients. However, the contributing factors that potentially cause oxidative stress in PD are still elusive. To a certain extent, the identification...
