Impact of genome instability on transcription regulation of aging and senescence.

Abstract excerpt

Genomic instability has been implicated as a major stochastic mechanism of aging. Using a transgenic mouse model with chromosomally integrated lacZ mutational target genes, mutations were found to accumulate with age at an organ- and tissue-specific rate. Also, the spectrum of age-accumulated mutations was found to differ greatly from organ-to-organ; while initially similar, mutation spectra of different tissues...
