Journal ArticleDOI

Mitochondrial point mutations do not limit the natural lifespan of mice

TL;DR: The results strongly indicate that mitochondrial mutations do not limit the lifespan of wild-type mice and that the mutation frequency in mouse mitochondria is more than ten times lower than previously reported.
Journal ArticleDOI

Human cancers express a mutator phenotype

TL;DR: Measurements of random single-nucleotide substitutions in normal and neoplastic human tissues indicate that accelerated mutagenesis prevails late into tumor progression, and suggest that elevation of random mutation frequency in tumors might serve as a novel prognostic indicator.
Journal ArticleDOI

DNA deletions and clonal mutations drive premature aging in mitochondrial mutator mice.

TL;DR: It is demonstrated that the rate at which mtDNA mutations reach phenotypic expression differs markedly among tissues, which may be an important factor in determining the tolerance of a tissue to random mitochondrial mutagenesis.
Journal ArticleDOI

Heterogeneity of tumor-induced gene expression changes in the human metabolic network

TL;DR: Overall, the metabolic gene expression program in tumors is similar to that in the corresponding normal tissues, and many hundreds of metabolic isoenzymes show significant and tumor-specific expression changes, which are potential targets for anticancer therapy.
