Research summary

The paper claims that the accumulation of mutant mitochondrial DNA heteroplasmy is a significant marker of aging. This research addresses the underlying mechanisms of aging by exploring mtDNA mutations, which are relevant to understanding the biological processes that contribute to longevity and age-related decline.
