Outline of Final Research Achievements

It remains unclear whether the AhR signaling affects the TMJ. The aim of this study was to investigate possible mechanisms of bone loss in the TMJ due to the epigenetic alteration such as smoking. In particular, whether benzo[a]pyrene (B[a]P) induces expression of Cyp1a1 in the mandible. Possible functions of an endogenous ligand FICZ were investigated in a TMJ-OA mouse model. B[a]P was administered orally to mice and bone metabolism was examined. TMJ-OA was induced in WT mice with forceful opening of the mouth, and therapeutic functions of FICZ were detected. Exposure to B[a]P accelerated bone loss in the mandible. This bone loss manifested with osteoclastic bone resorption. In a TMJ-OA model, FICZ exhibited a dose-dependent rescue of subchondral bone loss by repressing osteoclast activity. Pretreatment with FICZ reduced RANKL-mediated osteoclastogenesis. B[a]P regulates subchondral bone metabolism via the Cyp1a1. FICZ can prevent TMJ-OA by regulating osteoclast differentiation.

Academic Significance and Societal Importance of the Research Achievements

以上の研究結果より、AhRリガンドであるBaP及びFICZ投与により、下顎頭において各々異なる作用を示し、AhRリガンド刺激によるCyp1a1を介したAhR活性化経路が破骨細胞分化において重要な役割を果たしていることが示唆された。これらの所見は、TMJ-OAを含めたAhR関連の炎症性骨代謝疾患に対する新しい治療方法への開発及び臨床応用に大きな意義を有することが期待される。
