摘要:

目的探讨环氧化酶-2(Cox-2)抑制剂塞来昔布对人舌鳞癌细胞系Tca8113侵袭、黏附及基质金属蛋白酶-2(MMP-2)分泌的影响。方法Tca8113细胞经塞来昔布作用24 h后,免疫组织化学方法检测细胞Cox-2蛋白表达,细胞外基质黏附实验检测细胞黏附力,Boyden侵袭小室测定细胞的侵袭力,酶联免疫吸附法检测培养液中MMP-2的水平。结果Tca8113细胞经塞来昔布作用24 h后,Cox-2蛋白表达明显受到抑制,Boyden侵袭小室细胞穿膜数和细胞外基质黏附率明显降低,同时,培养液中MMP-2水平也明显降低。结论Cox-2抑制剂塞来昔布可抑制Tca8113细胞Cox-2蛋白表达,其抑制细胞侵袭力和黏附率作用可能与抑制MMP-2分泌有关。

Abstract:

Objective To 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. Methods Following 24 h incubation with celecoxib, the Tca8113 cells were detected for cell adhesion and migration using cell adhesion as-say and Boyden chamber invasion assay. The expression of cyclooxygenase-2(Cox-2) protein in Tca8113 cells was detected 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 with 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. Conclusion Cox-2 inhibitor celecoxib can significantly inhibit the adhesion and migration of Tca8113 cells. The inhibitory effect on adhesion and migration may be correlative with its effect on decrese of Cox -2 protein expression and secretion of MMP-2 in Tca8113 cells.
