Outline of Final Research Achievements

In this study, a method for the enrichment of O-GlcNAcylated peptides using two-step click chemistry was developed. Analysis of O-GlcNAcylated proteins was performed using extracts from rat kidney tissue. A total of 34 O-GlcNAcylated peptides from 28 proteins were identified. Of these, 2 proteins were increased and 7 proteins were decreased in diabetic rat.

Academic Significance and Societal Importance of the Research Achievements

タンパク質のO-GlcNAc化は血糖値によって変化することから、糖尿病において重要な修飾である。本研究課題により、糖尿病モデル動物の腎臓で増加あるいは減少するO-GlcNAc化タンパク質の同定に成功した。今後、これらの生物学的な意義を明らかにすることで、糖尿病性腎症の病因・病態の解明に繋がる可能性がある。
