CD4 and neoplasm: To initially determine how expression of glycolysis-related genes correlated with tumor immune infiltration, we created a minimal selection of glycolysis genes (one for each of the 10 steps of glycolysis, plus the glucose transporter GLUT1 (SLC2A1), lactate dehydrogenase A (LDHA) and the lactate transporters SLC16A1 and SLC16A3) and immune genes (consisting of the ‘identity’ genes CD3, CD4, CD8 and the cytotoxicity genes Granzyme A (GZMA) and Perforin 1 (PRF1)).
