OBJECTIVETo investigate the effect of celecoxib on adhesion, invasion, migration and matrix metalloproteinase-2(MMP-2) expression of tongue squamous cell carcinoma cell line Tca8113 cells.

METHODSFollowing incubation with celecoxib, the Tca8113 cells were detected for cell adhesion and migration using cell adhesion assay and Boyden chamber invasion assay. The expression of cyclooxygenase-2 (Cox-2) protein in Tca8113 cells was tected with SP immunohistochemistry staining. The MMP-2 level in supernatant was detected with enzyme-linked immunosorbent assay. RESULTS; The adhesion and Boyden chamber invasion assays showed that, after treatment celecoxib, the ability of adhesion and migration of Tca8113 cells was significantly inhibited. Celecoxib could decrease the expression of Cox-2 protein in Tca8113 cell and decrease the MMP-2 level in supernatant.

CONCLUSIONCox-2 inhibitor celecoxib can significantly inhibit the adhesion and migration of Tca8113 cells. The inhibitory effect on hesion and migration may be correlative with its effect on decrese of Cox-2 protein expression and secretion MMP-2 in Tca8113 cells.
