We present important findings linking DNA repair pathways with stem cell exhaustion during ageing, as well as in specific cancer-related mutational patterns. Moreover, we put forward a general model, in which remaining cellular lifespan determines which DNA damage response strategy is used by the cell.
Such a model provides an explanation for the segmental ageing phenotypes of human progeroid syndromes and DNA repair-deficient corresponding mouse mutants, as well as the different aging trajectories between organs and tissues during natural ageing.
