Distinguished from several other glucose transporters, GLUT1 is a facilitative glucose transporter that belongs to the solute-linked carrier gene family SLC2 and is overexpressed ubiquitously in human cancer cells (Ganapathy et al., 2009), including breast, lung, renal, colorectal, and pancreatic cancers (Szablewski, 2013), which has potential effects on glycolysis process in cancer (Shang et al., 2020). Here, SLC2A1 is linked to cancer.
