Abstract: AIM: To investigate the effects of aspirin and sulindac on the expression of cyclooxygenase-2(COX-2), vascular endothelial growth factor (VEGF), CD44V6 and laminin receptor (LN-R) in 3AO cells. METHODS: The growth inhibition effects of aspirin and sulindac in 3AO cells were tested by MTT assay.The expression of COX-2, VEGF, LN-R and CD44V6were evaluated by immunocytochemistry.RESULTS: Aspirin and sulindac significantly inhibited the growth of 3AO cells whether added before or after cells adhered.When the pH was adjusted with sodium bicarbonate, the inhibition had a little decrease.Aspirin and sulindac also inhibited the expression of COX-2 and VEGF.But there were no effect on the expression of LN-R and CD44V6.CONCLUSION: Inhibited expression of COX-2 may down-regulate the expression of VEGF, and inhibit the angiogenesis of tumor.Aspirin and sulindac may exert their chemopreventive and anticancer effects by inhibiting the expressions of COX-2 and VEGF.

Key words: aspirin, sulindac, cyclooxygenase-2, vascular endothelial growth factor, laminin receptor, CD44V6
