Short but Long Lived
Long-life’ genes found in 100-year-old humans
It’s not quite the elixir of life, but researchers have at last identified gene variants that make people live longer. Men may miss out, as all carriers identified so far are women. They are also slightly shorter than average.
Yes! Finally the odds are tipped in my favour.
It’s interesting to note the mechanism affected by by the genes.
Both mutations affect the receptor for insulin-like growth factor 1 (IGF1), a driver of bodily growth and maturity, especially during puberty. By making the receptor slightly faulty, the mutations may disrupt IGF1 binding and decelerate the process of maturation and ageing.
