    Résumé

    Epithelial cancers of the elderly are caused by a combination of telomere dysfunction and the mutational invalidation of major tumor suppressors including p53. A recent article published in Cell by Davoli et al. shows that the simultaneous elimination of p53 and telomerase causes a state of chronic DNA damage that results in tetraploidization through endoreplication, that is, two consecutive S phases that are not separated by mitosis. As tetraploid cells represent a metastable intermediate between normal diploidy and cancer-associated aneuploidy, this novel route to tetraploidization may constitute (one of) the functional link(s) between aging and carcinogenesis.
