SLC2A1 and osteosarcoma: Both GLUT1 and GLUT3 have been detected in rat UMR-106 osteosarcoma cells (Thomas et al., 1996) and immortalized rat osteoblast cell line PyMS (Zoidis et al., 2011), while the presence of only GLUT1 has been reported in human osteosarcoma cell lines MG-63, Saos-2, and U-2 OS (Cifuentes et al., 2011), and in murine MC3T3-E1 and ST2 cell lines (Takeno et al., 2018).
