Outline of Final Research Achievements

One of the Ca binding proteins, Annexin group, Anxa5 is localized to bone attachments of tendon and ligament (enthesis). We have found that Anxa5 KO mice have bone overgrowths at entheses. The present analyses of gene expression in knockdown cells and immuno-histology using tissue sections of KO mice showed that mineralization at the enthesis may be regulated by pyrophosphates and/or mechanical loading. Anxa5 KO mice with bone overgrowths at entheses exhibit depression behavior. A behavior testing revealed that KO mice exhibit decreases of regulation of physical function. We suggest that this phenotype is due to deletions of Anxa5 localizations in the central nervous system.
Rescue experiment with recombinant protein for the phenotypes of KO mice would be required.

Academic Significance and Societal Importance of the Research Achievements

学術的意義:①腱・靭帯の骨への付着部は運動機能の上で重要な機能を担っている。本研究によりAnxa5の末梢、中枢における機能を介したenthesisへの関与を明らかにすることは、enthesisの中枢・末梢における制御機構の解明に寄与できる。②マウスにおけるAnxa5のうつ病様行動への影響のメカニズムを明らかにすることにより、海外研究協力者が同定したヒトにおける遺伝子変異を持った患者の病態発症メカニズム解明に寄与できる。
社会的意義:Anxa5リコンビナントタンパク投与によるレスキューから得られる結果は、ヒトAnxa5欠損による病態の治療法に応用できる可能性を有すると言う点で、社会的意義が高い。
