ST3GAL4 and cutaneous melanoma: The same is the case for epithelial cells from normal colon or colorectal cancer, which express Galectin-3 (LGALS3) and 4 (LGALS4); hepatocytes from normal tissue and hepatocellular carcinoma (HCC) express ST6GAL1 and UGT2B4; and melanocytes derived from cutaneous SCC (healthy) and cutaneous Melanoma (malignant), that both show the expression of ST3GAL4 and ST3GAL6 (Figure S7A).
