Outline of Final Research Achievements

In nerve-specific Ubqln2 CKO mice, the Wire-hang test showed promising findings suggestive of hypokinesia, but the phenotype was minor. Therefore, for the purpose of further testing the hypothesis of loss of function, mice expressing Cre under the Thy1.2 promoter (Thy1-cre / ERT2, -EYFP) induced by Tamoxifen were mated with Ubqln2-flox mice, and the growth and development phase was passed. After that, we established a strain of a model mouse that arrests Ubqln2 expression in a nerve-specific manner, and evaluated motor function.

Academic Significance and Societal Importance of the Research Achievements

これまでの研究では筋萎縮性側索硬化症の病態は不明な点が多く、現時点では進行を止める治療法は見いだされていない。本研究では、家族性筋萎縮性側索硬化症の原因として明らかとなっているUBQLN2に着目し、神経特異的なノックアウトを作成することにより、Loss of functionの観点からUBQLN2の病態を明らかにすることを目的としている。
