| Research Abstract |
The aims of this study were to systematically investigate the possible involvement of proteins at the cell surface in controlling cell motility and angiogenesis, and further identify the cell surface molecules involved in malignant tumors. We addressed these issues using functional human monoclonal antibodies (MAbs), which inhibit cell motility. In addition, we established human monoclonal antibodies using KM mice. We have established 11 monoclonal antibodies which suppress lung metastasis. Among them, 7 kinds of monoclonal antibodies have recognized proteins and the others were directed to sugar chains like glycoproteins and glycolipids. Previously, we established a murine MAb MH8-11, which inhibits cell motility and in vitro angiogenesis. This epitope was a 165-kD protein and the sequencing analysis revealed that it was almost identical to aminopeptidase N (APN)/cluster of differentiation 13 (CD13). The APN transfected B16-F1 gained a potential ability of metastasis to the lung. Using the actual clinical specimens of lung cancer, colon cancer and pancreatic cancer, we found that the expression of APN had an association with angiogenesis, and was a significant factor of a poor prognosis. Currently, as the molecular targeting therapy, we established the human monoclonal antibodies recognizing APN. MT95-4 has a stronger ability suppressing APN enzyme activity than the mouse monoclonal antibody MH8-11. Using the F1 cell line with highly metastatic potential to the lung, we demonstrated that MT95-4 MAb efficiently prevented the pulmonary metastasis of F1. Using MT95-4 we might be able to treat the various kinds of cancers as a molecular targeting therapy.
