Fig. 3: GLUT1 promotes growth and metastasis in vivo.

a GLUT1 upregulation enhanced RBE cell xenograft tumor growth in nude mice, while GLUT1 knockdown reduced HuCCT1 growth. b The expression of MMP2 and cyclin D1 was evaluated using western blot assays with xenograft tissues. c IHC staining was used to detect Ki-67 expression in xenograft tissues. d Representative bioluminescence images, gross specimens, and hematoxylin and eosin (H&E) staining of the lung tumors are shown in the left panels. The number and incidence of nodules are displayed in the right panels. Bar = 100 μm. Data are means ± SD of three independent experiments. **P < 0.01; ***P < 0.001.
