Abstract

Although the function of vascular endothelial growth factor in the induction of tumor angiogenesis is well understood, the role of a second group of angiogenic factors, the fibroblast growth factors (FGFs), remains elusive. We used a recombinant adenovirus expressing soluble FGF receptor (AdsFGFR) to interfere with FGF function in tumor angiogenesis. AdsFGFR repressed endothelial cell proliferation in vitro and inhibited tumor angiogenesis in an ex vivo bioassay, in which endothelial cells were cocultured with angiogenic tumor biopsies in a collagen gel. Moreover, AdsFGFR repressed tumor angiogenesis and hence tumor growth in vivo in allograft transplantation experiments. Whereas adenoviral expression of a soluble form of VEGF receptor 1 (AdsFlt) predominantly affected the initiation of tumor angiogenesis, soluble FGF receptor (sFGFR) appeared to impair the maintenance of tumor angiogenesis. The combination of sFGFR and soluble Flt exhibited a synergistic effect in the repression of tumor growth. Finally, i.v. injection of AdsFGFR resulted in a dramatic repression of tumor growth in a transgenic mouse model of pancreatic β cell carcinogenesis. Similar to control infections with AdsFlt, tumor-associated vessel density was decreased, indicating that the expression of sFGFR impaired tumor angiogenesis. These data indicate that FGFs play a critical role in tumor angiogenesis.
