Agarwal, B. published the artcileCox-2 is needed but not sufficient for apoptosis induced by Cox-2 selective inhibitors in colon cancer cells, COA of Formula: C20H17FO4S, the publication is Apoptosis (2003), 8(6), 649-654, database is CAplus and MEDLINE.

The role of Cox-2 in NSAID-induced apoptosis is debated. We studied the role of Cox-2 inhibition in apoptosis induced by a selective Cox-2 inhibitor, SC 236 (a structural analog of celecoxib) in two colon cancer cell lines, HT29 (expressing Cox-2 protein) and HCT116 (not expressing Cox-2 protein). Apoptosis was quantified by flow cytometry. SC 236 0-75 μM decreased cell numbers and induced apoptosis to identical levels in HT29 and HCT116 cells. However, SC 236, concentrations >75 μM reduced Cox-2 protein expression in HT29 cells and induced greater levels of apoptosis in HT29 than in HCT116 cells. In contrast, sulindac sulfide (SSD) (which inhibits Cox-1 and Cox-2) 0-200 μM or sulindac sulfone (SSN) 0-500 μM (without significant activity against Cox-1 or Cox-2) caused identical decreases in cell number and increases in apoptosis in HT29 and HCT116 cells. Neither SSD nor SSN altered the expression of Cox-2 in HT29 cells. To determine that the higher levels of apoptosis in HT29 cells with SC 236 >75 μM were related to decreased Cox-2 protein levels, we decreased Cox-2 protein expression in HT29 cells with curcumin (diferuloylmethane) and studied its effect on SC 236-induced apoptosis. Curcumin augmented apoptosis induced by SC 236 in HT29 cells but not in Cox-2 lacking HCT116 cells. In conclusion, selective Cox-2 inhibitors can induce apoptosis independent of Cox-2 expression. However they may selectively target cells that express Cox-2 by decreasing their Cox-2 protein expression.
