| Outline of Final Research Achievements |
Adam10 and Adam17 were abundantly expressed during articular cartilage degeneration of mouse osteoarthritis model. When we suppressed them by their specific siRNA, hypertrophic differentiation of chondrocytes was inhibited. As downstream signal, we showed that Hes1 promoted cartilage degeneration by inducing Adamts5 and Mmp13. We further performed microarray analysis and identified IL6 and IL1RL1 as its direct target.
