Outline of Research at the Start

胆管発生メカニズムは非常に複雑で未解明な部分が多く残されている。また、慢性肝疾患の病態進行に関わる現象の一つに細胆管反応があるが、細胆管反応のメカニズムも未解明の部分が多く残されている。申請者らはいずれにもSOX9が関与していることを発見しており、本研究はSOX9とSOX9関連シグナル経路の動態について幅広く解析・理解し、将来的に肝疾患への新規治療構築への基盤とする研究である。

Outline of Final Research Achievements

Our preliminary experiments indicated that SOX9 may play a critical role in the normal development of the bile ducts. Therefore, this study was conducted using Sox9 conditional knockout (cKO) mice. Visualization of the bile ducts by clearing the liver revealed that at five weeks of age, the density of the bile ducts was significantly reduced in Sox9 cKO mice, and in particular, the capillary bile ducts were poorly visualized. Focal hepatic necrosis was observed and the liver enzyme ALT was significantly elevated. In the central region, there was poor development of CK19-positive bile ducts, while in the peripheral region there was an increase in the number of irregular small bile ducts. Periportal fibrosis was also observed. These findings suggested that there may be a problem with the formation of a network between the capillary and small bile ducts. We concluded that SOX9 may contribute to bile duct development.

Academic Significance and Societal Importance of the Research Achievements

前研究で行われた細胆管反応の進展メカニズムとSOX9との関連性に関する研究に加えて、本研究では胆管の正常発生にSOX9が関わっている可能性が示された。SOX9はアラジール症候群の原因遺伝子であるNotch2やJagged1が関わるNotchシグナル経路と密接なかかわりのある転写因子である。そのSOX9が持つ役割について新たな知見を見出すことができたことから、胆管発生の複雑なメカニズムの解明に貢献でき、かつ、先天的な胆管発生異常の解明の一助となる研究であると考えられる。
