	1	Suppression of a core metabolic enzyme dihydrolipoamide dehydrogenase (dld ) protects against amyloid beta toxicity in C.elegans model of Alzheimer’s disease显示文摘A decrease in energy metabolism is associated with Alzheimer’s disease(AD),but it is not known whether the observed decrease exacerbates or protects against the disease.The importance of energy metabolism in AD is reinforced by the observation that variants of dihydrolipoamide dehydrogenase(DLD),is genetically linked to late-onset AD.To determine whether DLD is a suitable therapeutic target,we suppressed the dld-1 gene in Caenorhabditis elegans that express human Ab peptide in either muscles or neurons.Suppression of the dld-1 gene resulted in significant restoration of vitality and function that had been degraded by Ab pathology.This included protection of neurons and muscles cells.The observed decrease in proteotoxicity was associated with a decrease in the formation of toxic oligomers rather than a decrease in the abundance of the Ab peptide.The mitochondrial uncoupler,carbonyl cyanide 4-(trifluoromethoxy)phenylhydrazone(FCCP),which like dld-1 gene expression inhibits ATP synthesis,had no significant effect on Ab toxicity.Proteomics data analysis revealed that beneficial effects after dld-1 suppression could be due to change in energy metabolism and activation of the pathways associated with proteasomal degradation,improved cell signaling and longevity.Thus,some features unique to dld-1 gene suppression are responsible for the therapeutic benefit.By direct genetic intervention,we have shown that acute inhibition of dld-1 gene function may be therapeutically beneficial.This result supports the hypothesis that lowering energy metabolism protects against Ab pathogenicity and that DLD warrants further investigation as a therapeutic target.
