The roles of the pha-4 and daf-16 genes in diet-restricted induced longevity are described and characterized. Pha-4 acts, e.g., in the absence of daf-16, to increase lifespan, e.g., in nematodes. Given the role that pha-4 and daf-16 play in the mediation of longevity, they represent targets for modulation of life span. Methods of increasing life span and delaying age onset diseases by modulation of pha-4 activity are disclosed, as are screening methods for identifying compounds that modulate pha-4 and/or daf-16 activity. In addition, recombinant animals expressing the pha-4 gene and not the daf-16 gene, and methods of using the pha-4 and/or daf-16 genes to modulate longevity and age-onset diseases are described.
