Outline of Final Research Achievements

Osteoclasts are responsible for bone resorption. In inflammatory disease such as arthritis and periodontitis leads to bone destruction due to the excess bone-resorbing activity of osteoclasts. We investigated roles of Wnt5a, a cytokine, in the osteoclast function. We have shown that Wnt5a-Ror2 signaling promotes osteoclast function through the activation of Daam2-Rho-protein kinase N3 (Pkn3)-c-Src signaling pathways.

Academic Significance and Societal Importance of the Research Achievements

破骨細胞の機能を促進するメカニズムとして、Wnt5a-Ror2シグナルの下流で、Rho-Pkn3-c-Src経路が重要であることを明らかにした。破骨細胞の機能亢進は、骨粗鬆症や炎症性疾患(関節リウマチや歯周病)における骨破壊の進行に重要である。そのため、破骨細胞の機能を分子レベルで明らかにすることは、破骨細胞の機能を抑制する低分子の探索につながる。これにより、骨粗鬆症や炎症性骨破壊の新たな治療薬の開発が可能となる。
