Abstract
Cellular senescence induced by different stresses and telomere shortening appears to play an important role in the aging process. The products of the INK4a/ARF locus - p16INK4a and ARF - arrest cell proliferation at the senescence stage by exerting their effects on retinoblastoma protein- and p53-mediated responsive pathways. A study in this issue of the JCI provides experimental evidence of a specific upregulation of these cell cycle inhibitors in a variety of organs during mammalian aging (see the related article beginning on page 1299).
