Genetic depletion of mTORC1 subunits, deletion of S6K1 or downstream substrates, or expression of dominant negative 4E-BP1 in specific tissues extends lifespan and healthspan of mice.
“Studies in mice have likewise shown that genetic depletion of mTORC1 subunits, deletion of S6K1 or downstream substrates, or expression of dominant negative 4E-BP1 in specific tissues extends the lifespan and healthspan of mice 13–16.”
From Targeting the biology of aging with mTOR inhibitors (2023) · cites this paper as [14]
The paper reports increased lifespan in S6K1-knockout mice (Extended Data Figure 5) and in mice carrying a phosphorylation-deficient mutation in the downstream effector EPRS (main text, page unavailable). It also reports improved glucose homeostasis and reduced adiposity, but does not establish an extension of healthspan. Its EPRS mutation is not described as a tissue-specific deletion, and the paper does not report lifespan extension from dominant-negative 4E-BP1. (LLM, conf=0.86)
Experimental — accuracy not yet measuredMice expressing EPRS S999A have reduced body weight and adipose mass, and increased lifespan, similar to mice lacking S6K1.
“Mice expressing EPRS S999A, which is non phosphorylatable, have reduced body weight and adipose mass, and increased lifespan, similar to mice lacking S6K1 14.”

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.
