1 Role of GLUT1 in regulation of reactive oxygen species. Reactive Oxygen Species solute carrier family 2 member 1 Homo sapiens
2 We hypothesized that conditions that would decrease GLUT1-mediated transport would cause increased reactive oxygen species (ROS) levels in L6 myoblasts, while conditions that would increase GLUT1-mediated transport would result in decreased ROS levels.

4 We found that the GLUT1 inhibitors fasentin and phloretin increased the ROS levels induced by antimycin A and the superoxide generator pyrogallol. Reactive Oxygen Species solute carrier family 2 member 1 Homo sapiens
5 Mutation of an ATM target site on GLUT1 (GLUT1-S490A) increased ROS levels and prevented the ROS-lowering effect of the ATM activator doxorubicin. Reactive Oxygen Species solute carrier family 2 member 1 Homo sapiens
6 Mutation of an ATM target site on GLUT1 (GLUT1-S490A) increased ROS levels and prevented the ROS-lowering effect of the ATM activator doxorubicin. Reactive Oxygen Species solute carrier family 2 member 1 Homo sapiens

9 In contrast, expression of GLUT1-S490D lowered ROS levels during challenge with pyrogallol, prevented an increase in ROS when ATM was inhibited, and prevented the pyrogallol-induced decrease in insulin signaling and insulin-stimulated glucose transport.
