Outline of Final Research Achievements

Parathyroid hormone (PTH) and parathyroid hormone-related peptide (PTHrP), and its receptor (PTH1R) play an important role not only in differentiation of bone and cartilage in the developing stages, also in tooth eruption. In this study, we have attempted to examine skeletal and alveolar bone abnormalities in Jansen type metaphyseal cartilage dysplasia. From this research, functional abnormality of Jansen type PTH1R appears to be due to their abnormal intracellular localization, presumably caused by the altered molecular structures different from wild type PTH1R. Furthermore, it is suggested that this functional abnormality may cause intrachondral and intramural ossification abnormalities in vivo.

Academic Significance and Societal Importance of the Research Achievements

申請者は小児歯科医であり、歯科臨床においては、骨・軟骨異常に伴い顎顔面や口腔内にも歯の萌出異常を含め、様々な異常を生じる疾患と遭遇する機会がある。これら骨・軟骨異常疾患を持つ患者への歯科的な対応としては、今のところ対症的治療しか行えない現実があるため、その度に少しでも苦痛を軽減させてあげられるような処置(特に対象が低年齢児であるほど)ができないものか考えさせられる。本研究により局所的な遺伝子治療、あるいは軟骨細胞や骨芽細胞を用いたテイッシュエンジニアリング等の応用が将来的に期待できるという学術的意義、さらに局所治療薬等の開発に役立つ情報が得られる社会的意義があると考える。
