| Outline of Final Research Achievements |
This study aimed to determine specific urine biomarkers of Alzheimer disease (AD) by using metabolomics. Urine samples of 9 AD patients and 9 controls were analyzed with predictive model and validation model. Two and 7 metabolites were increased and decreased, respectively in predictive model, and 3 and 6 metabolites, respectively, were in validation model. Especially, glycerol-3-phosphate was significantly decreased in the both model. It is suggested that urine glycerol-3-phosphate is a new biomarker.

| Academic Significance and Societal Importance of the Research Achievements |
本研究で見出された尿中glycerol-3-phosphateは、アルツハイマー病の新たなバイオマーカーの可能性があり、尿でアルツハイマー病が予測できることが期待される。また同時に、glycerol-3-phosphateが減少したことはアルツハイマー病におけるリン脂質代謝の異常を反映している可能性がある。今後は尿中の脂溶性代謝産物の変化についての解析を行うことが重要と考える。
