| Outline of Final Research Achievements |
The aim of this study is to identify the metabolic pathways characterized in the invaded cancer cells, PANC-1, whose invasiveness is enhanced after the carbon-ion (C-ion) irradiation, and propose the new candidates reducing the C-ion enhanced invasiveness. Metabolome analysis using CF-TOFMS showed that several metabolites in the glycolytic pathway, the uric acid pathway synthesizing arginine, and the folate pathway producing glutathione were all increased in the invaded PANC-1 cells compared to those of whole-cultured PANC-1 cells. Such increases in the metabolite were also shown in the invaded cells after the C-ion irradiation. From the results, we next clarified the enzymes responsible for the synthesis of increased metabolites found in the invaded cells. This approach would be useful for identifying new inhibitors for the invasion of cancer cells.
