Osteosarcoma (OS) causes millions of death worldwide and, since there is no effective therapy, it is necessary to identify the molecular mechanism of OS, which can direct the development of new therapies. This study investigated the role of bone morphogenetic protein 9 (BMP9), a member of the transforming growth factor (TGF)-β family, in OS development. This study first examined BMP9 expression in tissue from OS patients and normal subjects. The OS cell line (MG63) and tumor cells from OS patients were then transfected with BMP9 and cell proliferation and apoptosis were assessed.

Synergistic effect of BMP9 and TGF-β in the proliferation and differentiation of osteoblasts

We investigated the synergistic effect of bone morphoge­netic protein 9 (BMP9) and transforming growth factor (TGF)-b in the transformation of mesenchymal stem cells into osteoblasts. We evalu­ated the effect of BMP9 and TGF-b on the induction of osteoblast for­mation. Mitogen-activated protein kinase (MAPK) pathway-related pro­teins such as p38, extracellular receptor kinase 1/2, and c-Jun N-terminal kinase (JNK) were analyzed. The interactions between TGF-Smad and BMP-MAPK were also studied.
