1 BACKGROUND AND PURPOSE: This study was designed to determine the oxygen dependency for expression of the endogenous hypoxic markers carbonic anhydrase IX (protein: CAIX/gene: CA9), glucose transporter 1 (GLUT1/GLUT1), osteopontin (OPN/OPN) and lactate dehydrogenase A (LDH-A/LDHA), and how this expression was influenced by extracellular pH (pHe). Oxygen lactate dehydrogenase A Homo sapiens

Oxygen lactate dehydrogenase A Homo sapiens
4 RESULTS: Under normal pHe conditions, CA9, GLUT1 and LDHA gene expression was upregulated within 1-3h of anoxia, reaching near maximal values by 6h. Phenylalanine lactate dehydrogenase A Homo sapiens
5 Expression of CA9, GLUT1, OPN and LDHA was inhibited under hypoxic conditions when pHe was reduced to 6.3. Phenylalanine lactate dehydrogenase A Homo sapiens
