Fig. 2. GLUT1 promotes iCCA cell migration and invasion in vitro.
a The migration ability of iCCA cells was determined by wound-healing assays. The representative images were captured at 0 and 24 h. Bar = 300 μm. b and c Migration and invasion assays for the indicated cell lines after GLUT1 knockdown or overexpression. Bar = 100 μm. d Expression of MMP2, MMP7, and MMP9 was evaluated using western blot assays with the indicated processed cells and the corresponding control group. e MMP2 knockdown decreased the GLUT1-induced invasion of RBE cells. Bar = 100 μm. Data are means ± SD of three independent experiments. **P < 0.01; ***P < 0.001.
