Abstract:

BACKGROUND: Molecular features of osteosarcoma are not fully understood because of the complexity of osteosarcoma gene. In human osteosarcoma, there are highly expressed alkaline phosphatase, runt-related transcription factor 2 (Runx2) and bone morphogenetic protein 4 (BMP4), as well as slightly expressed desmin, S100 and neuro-specific enolase (NSE). However, whether markers of osteosarcoma are similar to those of human osteosarcoma remains unclear.
OBJECTIVE: To verify the canine osteosarcoma experiments simulating human disease model and to assess the expression of important markers for human osteosarcoma.
METHODS: Fifty-nine tissue sections of the canine osteosarcoma were used for immunohistochemical staining. The expression levels of alkaline phosphatase, desmin, S100, NSE, Runx2 and BMP4 were detected.
RESULTS AND CONCLUSION: Alkaline phosphatase, Runx2 and BMP4 were highly expressed in all tumors, while the expression of desmin, S100 and NSE was variable. The findings are similar to those found in human osteosarcoma, suggesting that canine animals can be used as the models for studying human diseases.
