Figure Lengend Snippet: Inhibition of GLUT1 Improves the Efficiency of Doxorubicin-mediated Growth Suppression in MDA-MB-231. MDA-MB-231 cells were treated with 0.5 μM doxorubicin (DOX) with or without WZB117 at 6 μM (a) or 10 μM (b) for 48 h, after which growth was assessed. Data are mean ± SE of five independent experiments for panel a and four independent experiments for panel b. *: p=0.04, **: p=0.0004. (c) MDA-MB-231 cells were treated with varying concentrations of WZB117 with or without 0.5 μM DOX for 48 h. Data are mean ± SE of three independent experiments *: < p,0.05. (d) MDA-MB-231 cells were transfected with control or GLUT1 siRNA for 48 h, protein extracted, cell lysate resolved in SDS-PAGE and immunoblotted with GLUT1. Loading control: GAPDH . Transfected MDA-MB-231 cells with control or GLUT1 siRNA were treated with 0.5 μM DOX for 48 h and live cells were counted using trypan blue. Data are mean of ± SE (n=3). * p= 0.02 (versus control siRNA), ** p=0.03 (versus control siRNA + DOX), *** p=0.02 (versus GLUT1 siRNA). (e) MDA-MB-231 cells were transfected with GLUT 1 expression plasmid or control vector, treated with 0.5 μM DOX for 48 h and live cells were counted using trypan blue. Data are mean of ± SE (n=3). * p= 0.04 (versus control vector), ** p= 0.03 (versus GLUT1 OE), *** p= 0.02 (versus control vestor + Dox)
