Aging is a key risk factor for a variety of devastating, chronic diseases, yet the biological factors that influence when and how rapidly cells deteriorate over time remain largely unknown. Now, for the first time, a research team has linked the function of a core component of cells’ machinery — which cuts and rejoins RNA molecules in a process known as “RNA splicing” — with longevity in the roundworm. The finding sheds light on the biological role of splicing in lifespan and suggests that manipulating specific splicing factors in humans might help promote healthy aging.
