Outline of Final Research Achievements

This research was aimed at visualizing human disease models of medaka in vivo using a high resolution Magnetic Resonance Imaging, “MR microscope”, and at monitoring a disease progression in an individual medaka in a long term to investigate disease mechanisms. First, to obtain a higher quality image, we developed a digitalized spectrometer, larger gradient coils and RF coils of the MR microscope. Second, using the upgraded MR microscope, we visualized a disease progression in a cancer model of medaka (p53 knockout) and showed that the disease might develop from a kidney, which was a hematopoietic organ. Third, we found that a transgenic medaka overexpressing a tau protein, which was considered to cause Alzheimer disease, showed a different behavior from wild type medaka with age.

Academic Significance and Societal Importance of the Research Achievements

MR顕微鏡では、ヒト疾患の小型魚類モデルを生きたまま、経時的に可視化できる。遺伝子や環境が均一であっても、疾患の進行は個体ごとに異なるため、同一個体で病態を追跡することが重要となる。また、動物愛護の観点からも重要である。MR顕微鏡を高性能化し、生きたままでのより詳しい病態解析が可能となった。また、ガン抑制遺伝子であるp53はヒトのガンの約半数に変異が認められており、本研究により、ガンのメカニズムの理解に貢献できた。さらに、アルツハイマー病の原因とされるタウタンパク質が及ぼす影響を短命のメダカのモデルで見出したことにより、加齢に伴う疾患のメカニズムの研究に重要なツールを提供できたと考えられる。
