We next examined effect of GLUT1 inhibitor BAY-876 on selenite-induced cytotoxicity of HCT116 cells and results demonstrated that an enhanced cytotoxicity was achieved by all the combinations of selenite and BAY-876, further supporting the sensitization effect of glucose deprivation on selenite-induced cytotoxic effect against HCT116 colon cancer cells (Figure 1C). The gene discussed is SLC2A1; the disease is colonic neoplasm.
