Description

The receptor for IGF1, IGF1R, mediates the activation of the IGF1-stimulated signalling cascade. Evidence from model organisms, including results from flies [187] and roundworms [239], relates IGF1R homologues to ageing, most likely as part of the GH1/IGF1 axis. Mice (129/SvPas genetic background) heterozygous for IGF1R live 26% longer, though it is unclear whether they age slower. Null mutants are not viable [18]. In the B6 genetic background however, IGF-1R+/- female mutants show only an 11% lifespan extension, while males do not show any changes in median lifespan and have a slightly shorter maximum lifespan [3549]. In male mice where IGF1R has been knocked out specifically in cardiomyocytes, cardiac ageing is attenuated. Fibrosis and expression of proinflammatory cytokines and NFKB1 are reduced when compared to wild type mice [4351]. IGF1R integrates nutrient and temperature homeostasis in mice and a reduction in IGF1R enhances the reduction of temperature and energy expenditure seen during calorie restriction. Therefore, IGF1 signalling plays a role in regulating hypothermia during calorie restriction [4502].

The IGF1/GH1 axis appears to impact on ageing in model organisms, including rodents, and so IGF1R may affect human ageing. In humans, IGF1R has been implicated with growth retardation [186], and genotype combinations in the human IGF1R and PIK3CB genes have been related to plasma IGF1 levels and longevity [141].
