Genome Evolution and Ageing
Since the 1970's the involvement of mitochondria in the ageing process has been recognized. As we age, there is clear evidence of the accumulation of a mosaic pattern cell from different tissues that are deficient in the enzymatic capacity of the mitochondrial respiratory chain. Much of the research attention has focused on either the action of radical oxygen species, or the accumulation of somatic mutations and/or chromosomal rearrangements in mitochondrial DNA and their physiological effects. However, new hypotheses on the unusual evolutionary balance between the nuclear and mitochondrial genome are being investigated, which may have implication on the ageing process.
