Figure 1From: Metabolic markers in relation to hypoxia; staining patterns and colocalization of pimonidazole, HIF-1α, CAIX, LDH-5, GLUT-1, MCT1 and MCT4 MCT4 and CAIX expression according to nodal stage. A significantly higher expression of MCT4 (p = 0.04, a) and CAIX (p = 0.05, b) was found in node-positive tumours. One tumor without nodal metastasis had a high CAIX expression of 17%. Interestingly, no HIF-1α expression was found in this tumor.Back to article page
