Fig. 4.22. Hypoxia-mediated metabolic adaptation for energy preservation. Activation of genes for glucose transporter-1 (GLUT-1 = 1) and glycolytic enzymes yields an increased glycolytic rate. H -ions produced are preferentially exported via a Na /H -antiporter (NHE-1 = 3) and a lactate /H -symporter (monocarboxylate transporter MCT-1 = 2) leading to a drop in extracellular pH (pH.). Low extracellular pH activates the membrane-bound ectoenzyme carbonic anhydrase IX (CA IX = 4). Key mechanism regulating intracellular pH in tumor cells when protons are produced is also shown (Na -depen-dent HCOs" /CL -exchanger = 5). HIF-Ia = hypoxia-inducible factor la, PHDs = prolyl hydroxylases, FIH = asparagyl hydroxylase, lac" = lactic acid...
