Abstract

Cancer is a disease of aging. The accumulation of mutations in individual cells over a lifetime is thought to be the reason. In this work, we explored an additional hypothesis: could p53 function decline with age, which would contribute to an enhanced mutation frequency and tumorigenesis in the aging process? The efficiency of the p53 response to γ-irradiation was found to decline significantly in various tissues of aging mice from several inbred strains, including lower p53 transcriptional activity and p53-dependent apoptosis. This decline resulted from a decreased stabilization of the p53 protein after stress. The function of the Ataxia-telangiectasia mutated (ATM) kinase declined significantly with age, which may then be responsible for the decline of the p53 response to radiation. Declining p53 responses to other stresses were also observed in the cultured splenocytes from aging mice. Interestingly, the time of onset of this decreased p53 response correlated with the life span of mice; mice that live longer delay their onset of decreased p53 activity with time. These results suggest an enhanced fixation of mutations in older individuals because of the declining fidelity of p53-mediated apoptosis or senescence in response to stress, and they suggest a plausible explanation for the correlation between tumorigenesis and the aging process.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • ROS levels in cells may be regulated by ATM kinase, and age-related declines in ATM expression can increase ROS.

    “Levels of ROS in cells may also be regulated by ataxia telangiectasia mutated (ATM) kinase, and age-related declines in expression of ATM can result in an increase in ROS in cells (77,78).”

  • As p53 response efficiency declines during aging, aerobic glycolysis is increased as well as the proinflammatory SASP via NF-κB signaling.

    “As the p53 response efficiency declines during aging [228], aerobic glycolysis is increased as well as the proinflammatory SASP via NF-κB signaling [155].”

  • Signaling from ATM and the response of other DNA repair proteins declines with age.

    “For example, signaling from the DNA damage kinase, ATM, and the response of other DNA repair proteins declines with age (Feng et al., 2007, Gorbunova et al., 2007).”
  • There is a decrease in p53 function with age.

    “Similarly, there is a decrease in p53 function with age (Feng et al., 2007).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
