Consistently, the results showed that the protein levels of both HIF-1α and GLUT-1 in LoVo tumor tissues were significantly higher than those in HT29 tissues (0.21 ± 0.006 vs. 0.16 ± 0.2 and 0.96 ± 0.03 vs. 0.69 ± 0.03, respectively, P < 0.05) (Fig. 5E–G). The gene discussed is SLC2A1; the disease is neoplasm.
