title: Prevalent expression of fibroblast growth factor (FGF) receptors and FGF2 in human tumor cell lines.
abstract: Basic fibroblast growth factor (FGF2) has potent mitogenic and angiogenic activities that have been implicated in tumor development and malignant progression. The biological effects of FGF2 and other members of the FGF ligand family are mediated by 4 transmembrane tyrosine kinase receptors (FGFRs). To better understand the roles of FGFRs in cancer, the expression of FGF2 and each of the 4 FGFRs was assessed by RNase protection analysis of 60 human tumor cell lines, representing 9 tumor types. Expression of at least one FGFR isoform was detected in 90% and FGF2 mRNA in 35% of the cell lines. Our comprehensive analysis of FGF2 and FGFR expression in human tumor cell lines provides evidence that FGF signaling pathways are active in a majority of human tumor cell lines, and lends support to the development of anti-tumor strategies that target FGFRs.
