Phosphatidylinositol 3-kinase catalyzes the reaction from PI(4,5)P2 to PI(3,4,5)P3 and is encoded by the age-1 gene known to regulate lifespan. Here the researchers found that the metabolite myo-inositol, which can be converted to PI(3,4,5)P3 extends worm lifespan and alleviates worm as well as mouse health decline during aging.
