Potential relevance to the human ageing process

Main reason for selection
Entry selected based on evidence directly linking the gene product to ageing in a non-mammalian animal model
Description

IRS1 and IRS2 mediate many of the cellular actions of insulin (INS). Results from model organisms suggest IRS1 is involved in the IGF1/GH1 axis that could regulate ageing. In Drosophila, loss of chico, an insulin receptor substrate, extends lifespan [188]. Median lifespan was extended 18% in knockout mice from both sexes and 32% in females. Female animals displayed signs of resistance to ageing markers in skin, bone, immune system, and motor dysfunction, in spite of mild, lifelong insulin resistance. Heterozygous animals had normal lifespans [1924]. IRS1 may also be involved in the extended lifespan of some mouse strains [292]. In humans, mutations in IRS1 have been associated with diabetes [1658] and atherosclerosis [1657]. While it appears that IRS1 plays a role in some human age-related pathologies, its exact impact on the human ageing process is unknown.
