Genome Evolution and Ageing

The accumulation of mitochondrial dysfunction with age is one of the nine classic hallmarks of the ageing process. Many different analyses have identified the age-related accumulation of cells displaying mitochondrial dysfunction in the tissues of long-lived animals. Molecular analyses have identified the accumulation of mitochondrial DNA point mutations, structural aberrations of the mitochondrial chromosome, and a decrease in the number of mtDNA copies found within each cell. The lab focuses on the following research questions – how do the mitochondria acquire these mutations? How do they clonally expand to lead to mitochondrial deficiency? What effects do these sporadic deficient cells have on organismal health and ageing?
