It has been shown that the interaction between the potent angiogenic factor; the vascular endothelial growth factor (VEGF) and its receptors (VEGFR-1 and VEGFR-2), plays a pivotal role in tumor development, including hepatocellular carcinoma (HCC). However, the properties of the respective VEGF receptor in the signaling transduction pathway of VEGF-mediated effects in HCC have not been elucidated yet. The aim of this study was to examine the respective signaling pathway of two VEGFRs in the VEGF-mediated murine HCC development and angiogenesis. We examined the signaling cascades of VEGFR-1 and VEGFR-2 in the VEGF-mediated HCC development in combination with a retroviral tetracycline (tet)-regulated (Retro-Tet) gene expression system, which can manipulate the gene expression in vivo by providing tet in the drinking water, as well as VEGFR-1 and VEGFR-2 specific neutralizing monoclonal antibodies (R-1mAb and R-2mAb, respectively). Both R-1mAb and R-2mAb significantly suppressed the VEGF-mediated tumor growth associated with reduction of the tumoral neovascularization, and the combination treatment with both mAbs almost completely attenuated the tumor development and angiogenesis. The protein kinase-C (PKC) and MEK1/2 activities in the tumor were markedly attenuated by treatment with R-2mAb, whereas R-1mAb did not alter these activities. These results suggested that both VEGFR-1 and VEGFR-2 play important roles, and lie in the different signaling cascades by which VEGF augments HCC development and angiogenesis.
