Mitochondrial DNA copy number correlates with oxidative stress and predicts mortality in nondiabetic hemodialysis patients

Oxidative stress is highly prevalent in hemodialysis patients and may contribute to ath-erosclerosis and mortality. The copy number of mi-tochondrial DNA (mtDNA) is affected by oxidative stress in blood circulation. This study aimed to test whether mtDNA copy number correlates with oxida-tive stress and predicts all-cause mortality in non-diabetic hemodialysis patients.
