SLC2A1 and neoplasm: Glucose transporters (GLUTs), as an important transmembrane protein family, regulate the entry of extracellular glucose into cells and serve as the “valve” to control the constant glucose uptake of cells.[11] Due to the “Warburg effect,” elevated expression levels of GLUTs have been observed in tumor cells to meet their requirements for enhanced glucose supply during the fast‐growing of tumors.[12] GLUT1, whose expression level is much higher than that of the other 14 human GLUTs family members, is considered as the main prognostic indicator for tumorigenesis.
