Cyclooxygenase-2 enzyme induces the expression of the α-2,3-sialyltransferase-3 (ST3Gal-I) in breast cancer. Aberrant glycosylation is a common feature of malignant change. Changes in mucin-type O-linked glycosylation in breast cancer can result in the expression of truncated core 1-based sialylated glycans rather than the cor
