Reduced Expression of the Proto-oncogene Myc Increases Mouse Longevity and Enhances Healthspan

MYC is a pleiotropic transcription factor that regulates numerous pathways and whose deregulation promotes cancer. Myc+/- mice have extended lifespan relative to their wild type littermates. To better understand the effects of the Myc+/- genotype on cellular processes, microarrays were performed on young (5 month) and old (24 month) Myc+/- and WT males in liver, skeletal muscle, and adipose tissues.
