Outline of Final Research Achievements

Mutations in the genes encoding Na,K-ATPase (Na pump) alpha2 and alpha3 subunit (ATP1A2 and ATP1A3, respectively) are associated with different neurologic disorders, such as rapid onset dystonia parkinsonism, alternating hemiplegia of childhood, and so on. However, pathophysiological bases of these disorders are still unknown and no cure has yet to be found. A preliminary experimental study shows that the level of ascorbic acids is decreased in the brains of Atp1a2 and Atp1a3 knockout mice (pathological model mice). The present study investigated 1. Functional coupling between Na pump alpha subunit and a transporter of ascorbic acid (SVCT2); 2. The level of oxidative stress of Na pump knockout mice; 3. Genetical link between Atp1a2/Atp1a3 and the gene encoding SVCT2. The results indicate increased level of oxidative stress is one of underlying pathological mechanisms in the Na pump related neurological disorders.

Academic Significance and Societal Importance of the Research Achievements

Naポンプαサブユニット遺伝子変異はさまざまな神経疾患をひきおこすことが報告されている。しかし、同じ変異がはいっていても発症しない場合と発症する場合があること、複数の神経疾患をひきおこし、多様な症状を呈すること、症状発現のきっかけがあること等、既知の神経疾患とは異なる表現型を示す。今回、病態モデルマウスを使い、酸化ストレス増加が発症に関わること、酸化ストレス増加がおこる脳部位を同定したこと、身体的ストレスが酸化ストレス増加につながることを示したことで、病態生理の一端を明らかにできた。酸化ストレスを標的とした新たな治療法への道筋をつけることができ、社会的意義を示すことができた。
