Objective:To investigate the effect of selective COX-2 inhibitor celecoxib on cell cycle arrest in Hepatocellular carcinoma cells. Methods:Three different human hepatoma cell lines HUH-7, Hep3B and HepG2, were used in this experiment. The cells were treated with various degrees of celecoxib for different time. The cell viability was detected by WST-8. The cell cycle of the hepatoma cells was analyzed by flow cytometry. Results:Celecoxib induced a significant decrease in cell viability in these three hepatoma cell lines. Flow cytometry showed a cell cycle arrest in G0/G1, and a weak arrest in G2/M checkpoint, when the cells were exposed to celecoxib 25 μmol/L for 24 h. And this effect seems to be stronger in 48 h. Conclusion:Celecoxib induce G0/G1 and G2/M cell cycle arrest in human hepatocellular cells, which may play an important role in hepatoma cell growth inhibition.
