Mitochondrial DNA deletions in Alzheimer's brains: A review

Abstract excerpt

Mitochondrial dysfunction and increased oxidative stress have been associated with normal aging and are possibly implicated in the etiology of late-onset Alzheimer's disease (AD). DNA deletions, as well as other alterations, can result from oxidative damage to nucleic acids. Many studies during the past two decades have investigated the incidence of mitochondrial DNA deletions in postmortem brain tissues of...
