Description

Study of 961 chinese subjects (424 longevity subjects and 537 younger controls) showed that the mtDNA content for individuals aged 40-70 years old decreases with age. Additionally, no reduction of mtDNA content is observed in nonagenarians and centenarians. Instead, nonagenarians and centenarians show a significant increase in mtDNA content compared to elderly people aged between 50 and 70 years.
