Abstract

Abstract: An interesting clue with regard to molecular mechanisms underlying age-associated cancers is the apparent defect in mitochondrial function. Recent studies demonstrate a progressive decline in mitochondrial function during aging. Studies have established that the decline in mitochondrial function is due to the accumulation of mutations in mitochondrial DNA. These observations suggest that the mitochondrial dysfunction that accompanies aging may exert a major influence on carcinogenesis.
