An ability to sense and respond to nutrient availability is an important requisite for life.
Nutrient limitation is among main factors to influence the evolution of most cellular processes.
Different pathways that sense intracellular and extracellular levels of carbohydtrates, amino acids,
lipids, and intermediate metabolites are integrated and coordinated at the organismal level
through neuronal and humoral signals. During food abundance, nutrient-sensing pathways
engage anabolism and storage, whereas limitation triggers the mechanisms, such as the
mobilization of internal stores including through autophagy. These processes are affected during
aging and are themselves important regulators of longevity, stress resistance, and age-related
