The normal-like samples did not stain for GLUT1, HK2, and LDHA, with the differences being significant and near-significant with regard to the LDHA and HK2 expression in the cancer sections (44.9% positivity for LDHA, p = 0.018; 35.5% positivity for HK2, p = 0.050). This evidence concerns the gene SLC2A1 and cancer.
