PG - 91-100 LID - S0006-2952(18)30030-3 [pii] LID - 10.1016/j.bcp.2018.01.030 [doi] AB - Caloric restriction (CR) is a dietary regimen that aims to reduce the intake of total calories while maintaining adequate supply of key nutrients so as to avoid malnutrition. CR is one of only a small number of interventions that show promising outcomes on health span and lifespan across different species. There is growing interest in the development of compounds that might replicate CR-related benefits without actually restricting food intake. Hydrogen sulfide (H(2)S) is produced inside the bodies of many animals, including humans, by evolutionarily conserved H(2)S synthesizing enzymes. Endogenous H(2)S is increasingly recognized as an important gaseous signalling molecule involved in diverse cellular and molecular processes. However, the specific role of H(2)S in diverse biological processes remains to be elucidated and not all its biological effects are beneficial. Nonetheless, recent evidence suggests that the biological functions of H(2)S intersect with the network of evolutionarily conserved nutrient sensing and stress response pathways that govern organismal responses to CR. Induction of H(2)S synthesizing enzymes appears to be a conserved and essential feature of the CR response in evolutionarily distant organisms, including nematodes and mice. Here we review the evidence for a role of H(2)S in CR and lifespan modulation. H(2)S releasing drugs, capable of controlled delivery of exogenous H(2)S, are currently in clinical development. These findings suggest such H(2)S releasing drugs as a promising novel avenue for the development of CR mimetic compounds. CI - Copyright (c) 2018 Elsevier Inc. All rights reserved.
