Results obtained in another study showed that transfection of GLUT1 antisense cDNA reduces the level of GLUT1 mRNA and cell proliferation in human leukemia cells [95], decreases glucose uptake and GLUT1 mRNA levels in MKN45 gastric cancer cell line [96], reduces in vitro invasiveness of rhabdosarcoma and glioblastoma cell line [94], and decreases glucose uptake and the level of GLUT1 mRNA and GLUT1 protein, as well as decreasing proliferation of HEp-2 laryngeal carcinoma cells [49]. The gene discussed is SLC2A1; the disease is leukemia.
