Contrasting, we did not find significant differences in the expression of key enzymes involved in the aerobic glycolytic pathway such as HKII, Pkm2 and Ldh. Thus differences in enzymatic activity may be present since previous findings relate the growth of C6 tumor cells to the high expression of Glut-1 coupled to glucose metabolism [40]. The gene discussed is SLC2A1; the disease is neoplasm.
