Outline of Final Research Achievements |
Articular cartilage is thought to exhibit tolerance against mechanical compression such as body weight loading on knee joint. On the other hand, mandibular condylar cartilage is sensitive to the mechanical loading. Orthodontic treatment uses this characteristics to modulate the growth at the mandibular condylar cartilage. In this research project, we hypothesized that epigenetic control of the anti-oxidative stress tolerance via the transcription factor, Nrf2, in the specificity of the condylar cartilage. To clarify the issue, we utilized in vivo and in vitro experiment, and revealed the possible epigenetic control of the anti-oxidative stress tolerance in the specificity of the condylar cartilage.

Academic Significance and Societal Importance of the Research Achievements |
膝関節軟骨と下顎頭軟骨を比較することで、両者のメカニカルストレス耐性にエピジェネティックな抗酸化ストレス耐性制御が関連していることが明らかとなった。 これは疾患耐性にエピゲノムが関連していることを示しており、学術的に大きな意義がある研究と思われる。
