- Description
Growth hormone (GH1) binds GHR to activate an intracellular signal transduction pathway that leads to the synthesis and secretion of IGF1. The GHR gene also encodes a soluble form called growth hormone binding protein (GHBP) that binds GH1 and likely serves as a reservoir of GH1 in the plasma.
Disruption of GHR causes dwarfism in mice, enhances insulin (INS) sensitivity, and significantly extends longevity [3]. Mice with disrupted GHR (GHRKO) do not live longer when subjected to calorie restriction, which suggests a role for GHR and possibly the associated GH1/IGF1 signalling in caloric restriction [1773]. Mice where GHR is interrupted in adulthood (aGHRKO) display many of the same traits as GHR knockout mice including reduced growth, high adiposity and enhanced INS sensitivity. However, only female animals show an increase in their maximal lifespan, the lifespan of male aGHRKO mice do not differ from the controls [4335]. Ames mice, which lack GH1 due to a mutation in PROP1, have increased health span and lifespan. Ames mice have been crossbred with GHRKO mice, producing a new lineage lacking both GH1 and the GHR. These mice have improved glucose tolerance and increased adiponectin levels. Whilst these mice show the same increased longevity as their progenitors they do not show any further increases in longevity [4374].
Humans with mutations in GHR suffer from Laron syndrome, which is characterized by short stature and a similar phenotype to GHR knockout mice. Whether the ageing process is modified in patients with Laron syndrome remains unclear [1345]. One study found evidence of cancer protection in individuals with GHR deficiency, but a normal lifespan [2035]. The d3-GHR genetic polymorphism modulates GH1 sensitivity in humans and has been found to positively affect male longevity. Multivariate regression analysis indicates that being d3 homozygous could add up to 10 years to male lifespan. Homozygous individuals also showed lower serum IGF1 levels [4508].
