Outline of Final Research Achievements

We examined the possibility that the increase in TXNIP protein expression with aging may cause skeletal muscle and brain atrophy.In the skeletal muscle, although TXNIP protein expression level increased with aging, exercise training did not decrease TXNIP protein expression. Similarly, in the brain, the expression level of TXNIP increased with aging. Exercise training at a young age reduced the TXNIP expression level in the brain, whereas exercise training at a old age did not reduce the TXNIP expression in the brain.

Academic Significance and Societal Importance of the Research Achievements

本研究の結果から、老化にともなって骨格筋や脳が萎縮する時に、TXNIP発現量が増加する可能性が示された。老化にともなう骨格筋や脳の萎縮は、それぞれサルコペニアと認知症の発症につながるが、そのメカニズムは十分明らかにされていない。このメカニズムにTXNIPが関与している可能性が示されたことから、老化にともなうサルコペニアや認知症予防の研究の発展に寄与する研究成果であると考える。
