These data underscore the loss of tumor suppressive pathways and activation of specific oncogenic mechanisms associated with osteosarcoma oncogenesis, while drawing attention to the role of RUNX2 expression as a potential biomarker of chemotherapy failure in osteosarcoma.

Our analyses show that the RUNX2 interactome may be constitutively activated in osteosarcoma, and that the downstream intracellular pathways are strongly associated with the regulation of osteoblast differentiation and control of cell cycle and apoptosis in osteosarcoma.

To study the expression pattern of the target genes from the hotspot amplicon and known candidate genes from 6p12-21, we did quantitative reverse transcription-PCR analysis of MAPK14, MAPK13, CDKN1A, PIM1, MDGA1, BTB9, DNAH8, CCND3, PTK7, CDC5L, and RUNX2 on osteosarcoma patient samples and seven cell lines.

Cell growth regulation of Runx2 is also observed in primary calvarial osteoblasts and other osteoblastic cells with relatively normal cell growth characteristics, but not in osteosarcoma cells (e.g.SAOS-2 and ROS17/2.8).

Antibodies raised to the unique C-terminal domain were shown to be reactive by immunoprecipitation and immunoblot assay, and were used in confocal immunofluorescence microscopy to reveal low level cytoplasmic staining in osteosarcoma and lymphoma cells that express high levels of Runx2 mRNA.

Stable clones of the human MG63 osteosarcoma cells (MG63-Ap and MG63-IIIc) overexpressing a splice variant form of FGFR2 with or without the S252W mutation (FGFR2IIIcS252W and FGFR2IIIc) showed a higher RUNX2 mRNA expression than parental MG63 cells.
