| Outline of Final Research Achievements |
2 - DG (2 - deoxy - D - glucose), a glucose metabolism inhibitor takes into tumor cells, but the amount of uptakes are depending on the phenotype of tumor cells. In our study, we established mice xenograft models with oral squamous cell carcinoma cell line , and we examined the antitumor effect by the combination of radiotherapy with 2-DG. As a result, in the group of the combination of radiotherapy with 2-DG, there is a significant tumor growth suppression compared with the control group and 2-DG alone. Our study suggested that 2-DG has synergistic effects when combined with radiotherapy, which might lead to the design of an effective metabolic target therapy.
