Research Abstract

新生児期には、肝内胆汁うっ滞、多種アミノ酸血症、ガラクトース血症などを、成人期では高アンモニア血症を伴う成人発症II型シトルリン血症を発症するシトリン(肝型アスパラギン酸・グルタミン酸ミトコンドリア膜輸送体)欠損症のモデルマウスを作成した。本研究では、その病態を解析し、アミノ酸、尿素合成異常だけでなく、糖代謝異常が大きな役割を果たしていることを明らかにし、ピルビン酸ナトリウムやアミノ酸混合物が、疾患モデルマウスの病態改善に有効であることを見いだした。さらに、ショ糖投与後、肝臓において解糖系中間体濃度が著しく増加することを見いだした。本現象は、今後有効な治療薬検定における有効なマーカーになる得るものと考えている。
