| Outline of Final Research Achievements |
To develop a potent inhibitor for the uPA binding, many types of peptides of amino acids were produced and their effect on the cancer invasion was investigated in the previous biochemical experiments. A computer ab initio molecular simulation has clarified that some amino acid residues of uPA play important roles in the specific binding between uPA and uPAR. In the present study, we propose KG6-Glu, KG7-Glu, KG8-Glu, KG9-Glu and KG10-Glu synthetic peptides and investigate the specific interactions and the binding affinity between uPAR and the peptides based on binding assay, Western blot, invasion and cell growth assay. We elucidated KG6-Glu peptide can bind more strongly to uPAR and propose a novel potent peptide which can inhibit the binding between uPAR and uPA efficiently. KG6-Glu peptide strongly inhibited tumor metastasis.
