Imaging targeted at tumor with 188Re-labeled VEGF189 exon 6-encoded peptide and effects of the transfecting truncated KDR gene in tumor-bearing nude mice

188Re-MAG3-QKRKRKKSRYKS can accumulate in tumor tissues, which could be increased by the transfection of truncated KDR gene. This study provides a basis for further applying the peptide to tumor targeted radionuclide imaging and treatment.
