| Outline of Final Research Achievements |
Articular cartilage is physiologically in a hypoxic condition, and HIF-1α is important for chondrocyte survival, differentiation, and metabolism. We tried to force rats to run on treadmill and evaluate that the production of HIF-1, 2α in articular cartilage were changed by running speed. Furthermore, by analyzing the mechanical stress application mechanism in hypoxic condition in vitro, We expected that genes different from regulating in normoxic condition may regulate cartilage metabolism in hypoxic condition.
