Outline of Final Research Achievements |
Our laboratory has identified pancreatic cancer-specific glycans (H-Type 1/3/4) using lectin microarray technology and clinically relevant animal models, and discovered a lectin, rBC2LC-N, which binds specifically to these glycans. We produced a fusion drug of lectin and endotoxin, which showed remarkable anti-tumor effects in a mouse pancreatic cancer model. Based on the results for pancreatic cancer, we are now preparing for lectin drug discovery, and have conducted research with a view to its application to colorectal cancer, which has a higher incidence than pancreatic cancer. In this study, we conducted experiments to elucidate glycan expression in colorectal cancer, to confirm its antitumor effect in mice, and to elucidate its pharmacokinetics, which will serve as a basis for the application of drug discovery to colorectal cancer, which our laboratory is promoting.
