| Outline of Final Research Achievements |
Many tumors including non-small cell lung cancer exhibit the Warburg effect, a metabolic state in which glucose oxidation is limited even in the presence of oxygen. However, the role(s) for the Warburg effect in carcinogenesis remains controversial. In this study, we asked potential mechanism in which the Warburg effect promotes tumor progression in non-cell-autonomous manner via reprograming their microenvironment. Our results suggest that the Warburg effect-like metabolism of tumor cells mediates immune-suppression.
