| Outline of Final Research Achievements |
Vascularization related molecules were expressed in growth plate and/or articular cartilage. In addition, we found the induction of such molecules in chondrosarcoma tissues and osteoarthritis cartilage. The association between the expression of vascularization related molecules and clinical parameters, including overall survival and disease free survival in chondrosarcoma patients, but no significant association could be found.
To find novel vascularization related molecules, we performed DNA microarray and VEGF promoter analysis and found some novel signalling pathways and molecules could induce VEGF. Finally, we examined if the VEGF inhibitor, sunitinib could inhibit chondrosarcoma progression or osteoarthritis progression. Sunitinib did not significantly affect the progression of chondrosarcomas in xenograft model and osteoarthritis in mouse knee osteoarthritis model.
