Vicente Miranda H, Gomes MA, Branco-Santos J, Breda C, Lázaro DF, Lopes LV, Herrera F, Giorgini F, Outeiro TF. Glycation potentiates neurodegeneration in models of Huntington's disease. Sci Rep. 2016 Nov 18;6:36798. PMID: 27857176; PMCID: PMC5114697.
From the abstract: "Protein glycation is an age-dependent posttranslational modification associated with several neurodegenerative disorders, including Alzheimer's and Parkinson's diseases. By modifying amino-groups, glycation interferes with folding of proteins, increasing their aggregation potential. Here, we studied the effect of pharmacological and genetic manipulation of glycation on huntingtin (HTT), the causative protein in Huntington's disease (HD). ... increased glycation enhanced HTT toxicity in human cells and neurodegeneration in fruit flies, impairing eclosion and decreasing life span. Overall, our study provides evidence that glycation modulates HTT exon-1 aggregation and toxicity ...."
