Outline of Final Research Achievements |
Epithelial to mesenchymal transition (EMT) is involved not only in normal conditions such as wound healing and development, but also in pathological conditions such as malignant progression of cancer and keloid formation. Therefore, a better understanding of the cellular biology of EMT is important for developing therapies to treat diseases. In this study, we demonstrated that a certain protein on the mitochondrial outer membrane affects mitochondrial function and, moreover, motility as a cellular function.

Academic Significance and Societal Importance of the Research Achievements |
本研究では,ミトコンドリアの外膜タンパク質が,酸化的リン酸化に影響を与えるだけでなく,細胞機能としての運動能に影響を与えることを示した点が新しく,さらにその外膜タンパク質のミトコンドリア上における局在が重要であることを示唆させるデータが得られた。この結果により,ミトコンドリア外膜タンパク質の新たな制御機構が示唆された点で,ミトコンドリアバイオロジーに新規の概念を提供できた。
