The polyphenol quercetin protects the mev-1 mutant of Caenorhabditis elegans from glucose-induced reduction of survival under heat-stress depending on SIR-2.1, DAF-12, and proteasomal activity.

Abstract excerpt

SCOPE: Hyperglycemia is a hallmark of diabetes mellitus but slighter increases of blood glucose levels are observed also during ageing. Using the Caenorhabditis elegans mev-1 mutant, we identified molecular mechanisms underlying the protection from glucose toxicity by the polyphenol quercetin. METHODS AND RESULTS: We fed C. elegans mev-1 mutants on a liquid medium supplemented with 10 mM glucose, which resulted...
