Integrins, the major class of alpha beta heterodimeric transmembrane glycoprotein receptors, play crucial roles in mediating tumor angiogenesis. Genetic ablation experiments combined with use of antibodies/peptide ligands for blocking either alpha(5) or beta(1), integrins have convincingly demonstrated alpha(5)beta(1) integrin to be unquestionably proangiogenic among the 24 known integrin receptors. Herein, we report on a novel RGDK-lipopeptide 1 that targets selectively alpha(5)beta(1) integrin and is capable of targeting genes to mouse tumor vasculatures.
