Abstract
Decline of cellular functions especially cognitive is a major deficit that arises with age in humans. Harnessing the strengths of small and genetic tractable model systems has revealed key conserved regulatory biochemical and signaling pathways that control aging. Here, we review some of the key signaling and biochemical pathways that coordinate aging processes with special emphasis on Caenorhabditis elegans as a model system and discuss how nutrients and metabolites can regulate lifespan by coordinating signaling and epigenetic programs. We focus on central nutrient-sensing pathways such as mTOR and insulin/insulin-like growth factor signaling and key transcription factors including the conserved basic helix-loop-helix transcription factor HLH-30/TFEB.
期刊介绍：
This journal examines the relationship between genetics and nutrition, with the ultimate goal of improving human health. It publishes original research articles and review articles on preclinical research data coming largely from animal, cell culture and other experimental models as well as critical evaluations of human experimental data to help deliver products with medically proven use.
