Short-lived killifish reveals link between gene expression, longevity

Wednesday, February 24, 2016 - 17:20 in Biology & Nature

It's well known that genetic differences among individuals influence lifespan, but a new study suggests that differences in patterns of gene expression in youth may also predict longevity. Researchers of the shortest-lived vertebrate -- the African turquoise killifish -- found that when genes involved in a cell's energy production are less active at a young age, the animals tend to live longer.
