The 3T3-L1 pre-adipocytes predominantly express the GLUT1 glucose transporter over GLUT4 [37]; the differentiated C2C12 myocytes and the primary cells the GLUT4 transporter and the H-4-II-E hepatoma cells the GLUT2 glucose transporter [38]. This evidence concerns the gene SLC2A2 and hepatocellular carcinoma.
