Assessment of Growth Parameters and Life Span of GHR/BP Gene-Disrupted Mice 1

Abstract

GH has many biological roles, including promotion of growth. Most, if not all, of its roles are achieved through interaction with its receptor. We chose to study the effects of loss of GH signaling on growth and aging in a mouse model for Laron Syndrome (LS) in which the GHR/BP gene has been disrupted. We observed that mice homozygous for the disruption (-/-) were significantly smaller than normal wild-type (+/+) mice as well as mice heterozygous for the disruption, even at 1.5 yr of age. IGF-I levels were also significantly lower in the -/- mice and remained low as the mice aged. IGFBP-3 levels were severely reduced in the -/- mice, whereas IGFBP-1, -2, and -4 levels remained unchanged. Finally, the -/- mice lived significantly longer than +/+ and +/- mice. The latter result contradicts the anti-aging GH data and suggests the need for further analysis of GH and aging.

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.
