Outline of Final Research Achievements

We idenitfied MUC16 and mesothelin, the genes associated with invasion in pancreatic cancer by expression profile. The downregulation of MUC16 and mesothelin by shRNA inhibited both invasion and migration of pancreatic cancer cell lines. Therefore, we focused on these genes as a tumor-specific antigen target for pancreatic cacer vaccine. We investigated thhe MUC16 or mesothelin-derived epitope peptide restricted to HLA-A*2402, and we determined their potential to induce peptide-specific T lymphocytes (CTL). After the expansion of each CTL, two CTL lines (each gene) were established. Finally, we could generate only one peptide-specific CTL clone. These results indictate that our identified mesothelin peptide is a novel HLA-A*2402 restricted CTL epitope, and that is a candidate for antigen-specific immunotherapy against pancreatic cancers.
