Outline of Final Research Achievements |
The aim of the study was to explore blood biomarkers (microRNA) for Alzheimer's disease which is one of the most frequent dementia all over the world. Previous results imply that single blood microRNA cannot be efficient enough for screening the patients. We propose a statistical meta-analysis theory to evaluate multiple blood microRNAs simultaneously and have been applying the theory to real world examples (multi-source = totally >30,000 studies).

Academic Significance and Societal Importance of the Research Achievements |
本研究成果により、認知症の過半数を占めるアルツハイマー病(AD)の早期発見・早期介入のための血液バイオマーカーが開発できる(社会的意義)。現在、軽度認知障害(MCI)等で実用化されている血液検査の改良につながる。一方、構築した理論はアルツハイマー病の血液miRNAバイオマーカーだけでなく、他の生体分子、重金属、さらには、他のさまざまな疾病の統合解析に適用可能である(学術的・社会的意義)。
