Potential relevance to dietary restriction and ageing

Observations

LAT1 is suggested to play a role in lifespan extension of DR. Deleting LAT1 abolishes replicative lifespan extension induced by 0.5% and 0.05% glucose restriction. In contrast, overexpressing Lat1 extends replicative lifespan, and this lifespan extension was not further increased by 0.5% glucose restriction. Similar to DR, replicative lifespan extension by LAT1 overexpression largely requires mitochondrial respiration [2317]. Interestingly, LAT1 overexpression does not require the Sir2 family to extend lifespan. Lat1 is also a limiting longevity factor in non-dividing cells in that overexpressing LAT1 extends cell survival during prolonged culture at stationary phase.
