Homeostatic systems mount adaptive responses to meet the energy demands of the cell and to compensate for dysfunction in cellular compartments. Such surveillance systems are also active at the organismal level: Nutrient and stress sensing in one tissue can lead to changes in other tissues. Here, we review the emerging understanding of the role of skeletal muscle in regulating physiological homeostasis and disease progression in other tissues. Muscle-specific genetic interventions can induce systemic effects indirectly, via changes in the mass and metabolic demand of muscle, and directly, via the release of muscle-derived cytokines (myokines) and metabolites (myometabolites) in response to nutrients and stress. In turn, myokines and myometabolites signal to various target tissues in an autocrine, paracrine, and endocrine manner, thereby determining organismal resilience to aging, disease, and environmental challenges. We propose that tailoring muscle systemic signaling by modulating myokine and myometabolite levels may combat many degenerative diseases and delay aging.
