A complex series of steps must take place to allow for a single cell to metastasize. Identifying factors responsible for these steps is essential in developing targeted therapy. We developed series of osteosarcoma cell lines with differing metastatic potentials. We used them to investigate mechanisms of metastasis and possible therapeutic targets for osteosarcoma metastasis to the lung in a nude mouse model. No correlation was found between epidermal growth factor receptor (EGFR), insulin-like growth factor receptor inhibitor (IGF-I-R), gelatinase, p53, metalloproteinase 9 (MMP 9), platelet derived growth factor receptor (PDGF-R), vascular endothelial growth factor (VEGF) and c-met expression and metastatic potential as measured by Northern analysis. By contrast, Fas expression inversely correlated with metastatic potential, and manipulation of Fas expression altered the metastatic phenotype of the cell. Our data indicate that fas gene expression may offer a new therapeutic target for the treatment of metastatic osteosarcoma in the lung.
