Mitochondrial impairment in p53-deficient human cancer cells

Abstract excerpt

The mechanism linking p53 inactivation to human cell malignancy remains unclear. Studies have indicated that mitochondrial dysfunction is involved in carcinogenesis. In this study we investigated the role of p53 in mitochondrial DNA (mtDNA) mutation and maintenance of proper mitochondrial function. We measured mtDNA mutation and found no difference in frequency of mutation between the p53(+/+) and p53(-/-) cell...
