Most cancers showed higher levels of GLUT1 than GLUT3 expression, while testicular germ cell tumors, mesothelioma, sarcoma, diffuse large B-cell lymphoma, thyroid carcinoma, pheochromocytoma/paraganglioma, and liver hepatocellular carcinoma showed higher levels of GLUT3 than GLUT1 expression (Figure 1A). This evidence concerns the gene SLC2A3 and diffuse large B-cell lymphoma.
