Objective  To evaluate the potential roles of celecoxib on proliferation and cell cycle progression of colon adenocarcinoma cells and on the hepatic metastasis of nude mice. Methods The human colon cancer cells HT-29 and HCT-116 were employed in the study. After treatment with celecoxib, the inhibitory effects of celecoxib on the proliferation of cancer cells were quantified by MTT assay, and the cell cycle progression was detected by flow cytometry, tumor cells were inoculated in nude mice, and the hepatic metastasis was detected. Results ①Celecoxib inhibited the proliferation of the tumor cells in time and dose-dependent manners (P<0.05,P<0.01). The inhibitory effect on HT-29 cells was ber than that on HCT-116 cells (P<0.05). ②Celecoxib changed cell cycle progression of both kinds of cells, and decreased the proliferation index of both kinds of cells too. ③Celecoxib could inhibit the growth of the hepatic metastatic tumor obviously. Conclusion Celecoxib may inhibit the activity of cyclooxygenase-2, and resulting in the inhibition of division and proliferation, apoptosis of tumor cells and interfering in metastasis and relapse of colon cancer.
