Vascular endothelial growth factor (VEGF) is an endogenous mediator of tumor angiogenesis. Blocking associations of the VEGF with its corresponding receptors (Flt-1, KDR/flk-1) have become critical for anti-tumor angiogenesis therapy, Previously, we synthesized PEI-g-PEG-RGD conjugate and evaluated as an angiogenic endothelial polymeric gene carrier. In this study, PEI-g-PEG-RGD/pCMV-sF1t-1 complexes are evaluated in terms of tumor growth inhibition in vivo. Complexes were repeatedly injected systemically via tail vein into subcutaneous tumor-bearing mice. As a result, tumor growth was inhibited in the PEI-g-PEG-RGD/pCN/1V-sFlt-1 injected group. However, this effect was not identified in PEI-g-PEG/pCMVsF1t-1 or PEI-g-PEG-RGD/pCNIV-GFP control groups. Moreover, the survival rate increased in the PEI-g-PEG-RGD/pCMV-sFlt-1 group compared with the controls group. These results suggest that delivery of pCMV-sFIt-1 using PEG-g-PEG-RGD may be effective for anti-angiogenic gene therapy. (c) 2006 Elsevier B.V. All rights reserved.
