To further examine whether inhibition of Glut1 suppresses osteosarcoma, cell migration and invasion assays were performed in primary osteosarcoma cells derived from Ctsk‐Cre;Trp53f/f/Rb1f/f mice with or without treatment with the Glut1 inhibitor BAY‐876 for 48 h. Here, SLC2A1 is linked to osteosarcoma.
