A high rate of glycolysis in cancer depends on key glycolytic enzymes and proteins, especially the glucose transporters GLUT‐1/GLUT‐3, hexokinase 2 and pyruvate kinase 2.6 The increased absorbance of glucose by overexpression of GLUTs contributed to the development of positron emission tomography using 18F‐labeled 2‐deoxy‐d‐glucose, which is used to visualize tumors within the patient's body.7 The gene discussed is SLC2A3; the disease is cancer.
