Abstract

Inhibition of the TOR signalling pathway by genetic or pharmacological intervention extends lifespan in invertebrates, including yeast, nematodes and fruitflies; however, whether inhibition of mTOR signalling can extend lifespan in a mammalian species was unknown. Here we report that rapamycin, an inhibitor of the mTOR pathway, extends median and maximal lifespan of both male and female mice when fed beginning at 600 days of age. On the basis of age at 90% mortality, rapamycin led to an increase of 14% for females and 9% for males. The effect was seen at three independent test sites in genetically heterogeneous mice, chosen to avoid genotype-specific effects on disease susceptibility. Disease patterns of rapamycin-treated mice did not differ from those of control mice. In a separate study, rapamycin fed to mice beginning at 270 days of age also increased survival in both males and females, based on an interim analysis conducted near the median survival point. Rapamycin may extend lifespan by postponing death from cancer, by retarding mechanisms of ageing, or both. To our knowledge, these are the first results to demonstrate a role for mTOR signalling in the regulation of mammalian lifespan, as well as pharmacological extension of lifespan in both genders. These findings have implications for further development of interventions targeting mTOR for the treatment and prevention of age-related diseases.

  • Rapamycin and rapalogs suppress the SASP by inhibiting mTOR and appear to extend healthspan and lifespan in mice.

    “Rapamycin and its analogs (so-called ‘rapalogs’) suppress the SASP by inhibiting mTOR and appear to extend healthspan and lifespan in mice105,108,109.”

    From Cellular senescence and senolytics: the path to the clinic (2022) · cites this paper as [108]

    The Abstract (page unavailable) reports that rapamycin inhibits the mTOR pathway and extends median and maximal lifespan in genetically heterogeneous mice. It does not report SASP suppression, effects of rapalogs, or an extension of healthspan; it says that whether mTOR inhibition alters other aspects of ageing remains to be tested. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Rapamycin treatment extended lifespan and postponed some ageing-related dysfunctions in mice.

    “Additionally, rapamycin treatment increased lifespan and delayed certain ageing-related dysfunctions in mice234.”

    From Cellular senescence in ageing: from mechanisms to therapeutic opportunities (2021) · cites this paper as [234]

    The Abstract reports that rapamycin extended median and maximal lifespan in mice. It does not establish that ageing-related dysfunctions were delayed; the paper says that demonstrating altered ageing would require testing age-dependent changes in multiple organs and processes. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Rapamycin's inhibition of SASP factors might explain its beneficial impact on longevity.

    “which might explain its beneficial impact on longevity [121,122].”

    From The role of cellular senescence and SASP in tumour microenvironment (2023) · cites this paper as [122]

    The Abstract reports that rapamycin extended median and maximal lifespan in mice. It discusses possible anti-neoplastic and cellular-stress mechanisms, but does not mention SASP factors or show that inhibiting them explains the longevity benefit (searched: SASP, senescence-associated secretory phenotype, senescent cells). (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Mice treated with rapamycin, a well-characterized inhibitor of mTOR, show marked increase in lifespan and enhanced health-span.

    “marked increase in lifespan and enhance health-span in mice treated with rapamycin, a well-characterized inhibitor of mTOR (Harrison et al., 2009)”

    From Protein Homeostasis and Aging: the importance of exquisite quality control (2011) · cites this paper as Harrison et al., 2009

    The Abstract (page not provided) reports that rapamycin inhibits the mTOR pathway and extends median and maximal lifespan in male and female mice. It does not establish enhanced health-span: disease patterns did not differ from controls, and the authors say that determining whether ageing was slowed would require testing age-dependent changes in multiple tissues and processes. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Rapamycin inhibits the production of SASP factors.

    “a well-known inhibitor of mTOR, rapamycin, inhibits the production of SASP factors”

    From The role of cellular senescence and SASP in tumour microenvironment (2023) · cites this paper as [122]

    The Abstract reports that rapamycin reduced phosphorylation of an mTOR-pathway target in mice, but it does not address production of SASP factors. Searches for SASP, senescence-associated secretory phenotype, and secretion by senescent cells found no passage supporting that specific claim in our copy. (LLM, conf=0.74)

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.
