SLC2A1 and hepatocellular carcinoma: Next, to confirm whether FOXM1 is required for the SLC2a1‐AS1‐mediated GLUT1 downregulation, we conducted cell transfection with control plasmids and SLC2A1‐AS1 overexpression plasmids, or cotransfected with SLC2A1‐AS1 and FOXM1 overexpression plasmids in HCC cells.
