Abstract:
Objective:To clarify the effects of the BMP receptor inhibitor LDN-193189 in the dedifferentiated chondrosarcoma (DDCS) cell line NDCS-1 and to explore the anti-tumor mechanism of LDN-193189 in DDCS. Methods:NDCS-1 was treated with 5 nmol/L of LDN-193189. MTT assay and clone formation experiments were used to verify that LDN-193189 suppressed cel proliferation. Transwel and wound healing tests were performed to demonstrate that LDN-193189 inhibited cell invasion. Western blot detection was used to show that LDN-193189 inhibited the suppression of BMPR2, p-Smad1/5, and RUNX2 protein expression. Results:The BMPR2 signaling pathway was inhibited by LDN-193189;thus, cell viability and invasion were significantly suppressed. Conclusion:LDN-193189 induces the inhibition of progression in vitro via the BMPR2-p-Smad1/5-RUNX2 signaling pathway in the human DDCS cell line NDCS-1.
