For example, galectin-7 genes (LGALS7 and LGALS7B) are expressed by cancer cells in SCC; fucosylation-related genes (GMDS, FUT2, FUT3) in Gastro-Intestinal cancers; MUC21 in Lung Adenocarcinoma; MUC16 in ovarian cancer; ST3GAL4 and ST3GAL6 in cutaneous and uveal Melanoma; GALNT6 and MUCL1 for non-TNBC breast cancer and ST6GAL1 and UGT2B4 for Liver Cancer (Figure 2D). The gene discussed is ST3GAL4; the disease is breast cancer.
