| Outline of Final Research Achievements |
Intervertebral disc degeneration (IDD) is a main contributor of low back pain and is a common clinical condition observed in more than 90% of the population. However, the actual molecular mechanism of IDD remains unknown. Here, we established a novel mouse IDD model in which instability is induced by resecting bilateral facet joints. Using this IDD model, we performed expression analyses by laser microdissectoin and RNA-seq. In consequence, we identified important signals and genes which may be associated with IDD.

| Academic Significance and Societal Importance of the Research Achievements |
本研究により生理的なマウス椎間板変性モデルを樹立できた。また、このモデルを用いた網羅的解析により椎間板変性に関与するいくつかの重要なシグナルおよび遺伝子群を同定する事が出来、椎間板変性研究の基板を構築することが出来たといえる。今後はこれらの遺伝子やシグナルの機能を解析し、椎間板変性発生の機序をより詳細に解析するとともに、治療標的となりうる物質の探索を行う。
