Cyclooxygenase-2 (COX-2) is an enzyme that helps catalyze the formation of prostaglandins, which promote inflammation, pain, and fever and maintain other normal physiological functions throughout the body. However, the overexpression of COX-2 has been found to play a role in various diseases including breast cancer. COX-2 exists as two major glycoforms— 72 kDa and 74 kDa— due to the glycosylation site Asn580 which is glycosylated 50% of the time. Past studies from our lab have shown that this glycosylation regulates COX-2 protein turnover in the cell3. The proteins E-cadherin— a tumor suppressor— and β-catenin— a tumor driver— can be regulated …
