Hexosamine pathway metabolites enhance protein quality control and prolong life.

Abstract excerpt

Aging entails a progressive decline in protein homeostasis, which often leads to age-related diseases. The endoplasmic reticulum (ER) is the site of protein synthesis and maturation for secreted and membrane proteins. Correct folding of ER proteins requires covalent attachment of N-linked glycan oligosaccharides. Here, we report that increased synthesis of N-glycan precursors in the hexosamine pathway improves ER...
