| Abstract | Neurodegenerative diseases including dementia with Lewy bodies, Lewy body variant of Alzheimer's disease, and Parkinson's disease are associated with the aberrant aggregation of alpha-synuclein, which is influenced by several post-translational modifications (PTM5). O-GlcNAcylation is one PTM that has an important role in many fundamental processes. The O-GlcNAcylation of endogenous a-synuclein at residues 53, 64, 72 and 87 has been reported in an unbiased mass spectrum analysis. The consequences of O-GlcNAcylation at residues 72 or 87 have been studied by using a synthetic a-synuclein bearing O-GlcNAcylation at threonine residue 72 or serine 87, respectively. O-GlcNAcylation at Thr72 or Ser87 suppresses the aggregation of alpha-synuclein. However, the effect of enzymatic O-GlcNAcylation of otsynuclein at multiple residues is not clear. Here, we successfully generated O-GlcNAcylated alpha-synuclein by co-expressing a shorter form of OGT (sOGT) with a-synuclein. The O-GlcNAcylation inhibited asynuclein aggregation and promoted the formation of soluble SDS-resistant and Thioflavine T negative oligomers. Our data warrant further studies on the role of O-GlcNAcylation in the progression/treatment of Parkinson's disease in animal models. (C) 2017 Elsevier B.V. All rights reserved. |
