Partial inhibition of mTORC1 in genetic mouse models can extend lifespan and healthspan in mice.
“Even partial inhibition of mTORC1 in genetic mouse models (e.g., S6K1−/−, mTOR+/− mLST8+/−, mTORΔ/Δ, TSC1tg) can extend lifespan and healthspan in mice 13,17–19.”
From Targeting the biology of aging with mTOR inhibitors (2023) · cites this paper as [18]
The Abstract reports that mTORΔ/Δ mice had approximately 20% longer median survival and preserved function in many, but not all, organ systems. However, it says these mice had reduced activity of both mTORC1 and mTORC2; the Discussion likewise describes a balanced reduction in both. This study therefore does not establish that partial inhibition of mTORC1 alone extends lifespan and healthspan. (LLM, conf=0.86)

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.
