Outline of Final Research Achievements

Aging is a risk factor for various diseases. For this reason, various interventions to delay aging have been investigated. Among them, dietary restriction and exercise are thought to exert their anti-aging effects partly through a common mechanism. In this study, we focused on the effects of gene-modified animal models of WD repeat protein 6 (WDR6), which is suggested to be important for such effects, and liver-specific functional inhibition by siRNA on the pathogenesis of obesity model mice and nonalcoholic steatohepatitis (NASH), respectively. The results suggest that inhibition of WDR6 function suppresses disease progression in both animal models.

Academic Significance and Societal Importance of the Research Achievements

WDR6は全身性に発現しているが、その機能はまだあまり解明されていない。本研究成果により、肥満症やNASHが誘導される際には、その病態進行を促進する可能性があり、そのためWDR6の機能を阻害することで病態進行を抑制することが可能であることが示唆された。これらの結果は、WDR6を標的とした肥満症およびNASHに対する新たな治療薬の開発が可能であることを示唆している。
