FIG. 3.
The suppression of anaerobic metabolism by p53 is mediated through multiple pathways. Glycolysis is inhibited by decreasing metabolic substrate availability through downregulation of glucose transporters and by modulating key enzymes in the glycolytic pathway hexokinase 2 (HK2), 6-phosphofructo-1-kinase (PFK-1), and phosphoglycerate mutase (PGM).
