| Outline of Final Research Achievements |
Glucose metabolism is often increased in human cancers, the significance of which for cancer cells remains mostly unclear. In this project, we conducted experiments to test the working hypothesis that glucose metabolism serves as a rheostat to determine the cell fate of glioblastoma stem cells. Inhibition of glucose metabolism through the inhibition of GLUT1, a facilitative glucose transporter, resulted in increased intracellular reactive oxygen species (ROS) level as well as in the loss of the stem cell properties of glioblastoma stem cells, which suggested the possibility that glucose metabolism could contribute to the maintenance of glioblastoma stem cells through the modulation of intracellular ROS level.
