Abstract

Rather than being a passive, haphazard process of wear and tear, lifespan can be modulated actively by components of the insulin/insulin-like growth factor I (IGFI) pathway in laboratory animals. Complete or partial loss-of-function mutations in genes encoding components of the insulin/IGFI pathway result in extension of life span in yeasts, worms, flies, and mice. This remarkable conservation throughout evolution suggests that altered signaling in this pathway may also influence human lifespan. On the other hand, evolutionary tradeoffs predict that the laboratory findings may not be relevant to human populations, because of the high fitness cost during early life. Here, we studied the biochemical, phenotypic, and genetic variations in a cohort of Ashkenazi Jewish centenarians, their offspring, and offspring-matched controls and demonstrated a gender-specific increase in serum IGFI associated with a smaller stature in female offspring of centenarians. Sequence analysis of the IGF1 and IGF1 receptor ( IGF1R ) genes of female centenarians showed overrepresentation of heterozygous mutations in the IGF1R gene among centenarians relative to controls that are associated with high serum IGFI levels and reduced activity of the IGFIR as measured in transformed lymphocytes. Thus, genetic alterations in the human IGF1R that result in altered IGF signaling pathway confer an increase in susceptibility to human longevity, suggesting a role of this pathway in modulation of human lifespan.

  • The activity of IGF-1/IGFR that elevates PI3K/Akt/mTor has been shown to act against longevity in animal and human studies.

    “The activity of IGF-1/IGFR that elevates PI3K/Akt/mTor has been shown to act against longevity in animal [110] and human studies [111,112].”

    The Results (page unavailable) report that IGF1R mutations found in centenarians were associated with reduced receptor levels and reduced AKT phosphorylation. The Discussion (page unavailable) says this suggests a role for reduced IGF signaling in human longevity, but calls that role controversial. The paper does not establish that increased PI3K/Akt/mTOR activity acts against human longevity; PI3K and mTOR are not addressed in the cited passages. (LLM, conf=0.87)

  • Polymorphisms in two IIS pathway genes, the IGF-1 receptor and the downstream FOXO3 transcription factor, have been associated with longevity and healthy ageing in humans.

    “Polymorphisms in two IIS pathway genes, the IGF-1 receptor and the downstream FOXO3 transcription factor, have been associated with longevity and healthy ageing in humans (62–64).”

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.
