Outline of Final Research Achievements |
Analysis of teeth extract from subjects with cleidocranial dysplasia and normal subjects revealed changes in protein localization of RUNX family transcription factor 2 (RUNX2) and connective tissue growth factor (CTGF/CCN2). Positive correlations were evident between RUNX2 and CTGF/CCN2 gene expression promotion and suppression in Saos-2 cells. Several RUNX2 protein candidate regions were identified that altered CTGF/CCN2 expression in Cos-7 cells. The findings indicate that the structure of RUNX2 protein changes depending on the mutation site of the RUNX2 gene, and that the CTGF/CCN2 expression changes accordingly. These changes result in an altered phenotype of cleidocranial dysplasia involved in tooth eruption.

Academic Significance and Societal Importance of the Research Achievements |
歯の形成において重要なRUNX2がCTGF/CCN2の発現を調節し,その調節機構を解析したことによって,歯の形成を指揮する重要なメカニズムの一端を解明する手がかりとなる結果を得た.これらの結果は,歯の再生医療を樹立するための基盤となり,また,鎖骨頭蓋異形成症患者においては,RUNX2遺伝子変異箇所の違いに対して,歯科的なオーダーメイド治療を行うための一助となる成果となったではないかと考えている.
