Over the past 10 years the signal transduction networks for p53, IGF-1-AKT, and TOR pathways have been assembled in worms, flies, and mammals, and their functions elucidated. In the past 1-2 years a number of genes and their proteins have been identified that permit extensive communication and coordination between these pathways. These three pathways are involved in sensing and integrating signals arising from nutrient and growth factor availability, signals from sensory and sexual organs, and intrinsic and extrinsic stress signals. In turn these pathways regulate cell growth, proliferation, and death. These networks are central to our understanding of a variety of physiological and pathological conditions, including cancer, diabetes, and longevity.
