What this study shows

Mice with growth hormone deficiency lived substantially longer than normal littermates - founding observation linking reduced growth-signaling to mammalian longevity.

Abstract

ShowHide

(Brief communication; no formal abstract in PubMed — editorial summary.) This landmark report shows that Ames dwarf mice, which carry a mutation causing combined deficiency of growth hormone, prolactin and thyroid-stimulating hormone, live substantially longer than their normal littermates (both sexes).

At a glance

Evidence type	A Animal model Marked A because it is an animal intervention or observation study measuring an organismal outcome (model: Ames dwarf mice (growth-hormone deficient)); the code names the system studied -- animal work can be rigorous and still not be human data.
Study type	4 - Animal Study
Model system	Ames dwarf mice (growth-hormone deficient)
Journal	Nature
Year	1996
Peer reviewed	Yes
Record last updated	2026-08-22
Source	DOI 10.1038/384033a0 · PMID 8900272

Extracted findings

Intervention	Genetic – Ames dwarf mutation (GH/prolactin/TSH deficiency)
Target	GH/IGF-1 axis (upstream of PI3K-Akt-mTOR)
Model	Mouse (Ames dwarf)
Effect	Substantially longer lifespan vs normal littermates (both sexes) – early evidence linking reduced growth signaling to longevity
