Sestrins are a family of proteins that respond to a variety of environmental stresses, including genotoxic, oxidative, and nutritional stresses. Sestrins affect multiple signaling pathways: AMP-activated protein kinase, mammalian target of rapamycin complexes, insulin-AKT, and redox signaling pathways. By regulating these pathways, Sestrins are thought to help adapt to stressful environments and subsequently restore cell and tissue homeostasis. In this review, we describe how Sestrins mediate physiological stress responses in the context of nutritional and chemical stresses (liver), physical movement and exercise (skeletal muscle), and chemical, physical, and inflammatory injuries (heart). These findings also support the idea that Sestrins are a molecular mediator of hormesis, a paradoxical beneficial effect of low- or moderate-level stresses in living organisms.
期刊介绍:
Since 1939, the Annual Review of Physiology has been highlighting significant developments in animal physiology. The journal covers diverse areas, including cardiovascular physiology, cell physiology, ecological, evolutionary, and comparative physiology, endocrinology, gastrointestinal physiology, neurophysiology, renal and electrolyte physiology, respiratory physiology, and special topics.
