ABSTRACT
Objective:
To investigate the effects of taraxerol and taraxeryl acetate on cell cycle and apoptosis of human gastric epithelial cell line AGS cells.Methods:
The inhibitory effects of taraxerol and taraxeryl acetate at different concentrations on AGS cell growth were measured by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) method and the concentrations of taraxerol and taraxeryl acetate to be used in following experiments were decided. Then, cell cycle analysis was performed by FACScan flow cytometry after culture with taraxerol or taraxeryl acetate. Annexin V-fluorescein isothiocyanate/propidium iodide staining was used to measure cell apoptosis.Results:
Taraxerol significantly inhibited AGS cell proliferation in a dose- and time-dependent manner. Taraxerol arrested the AGS cells at G(2)/M stage. 110 μmol/L taraxerol elevated the population of AGS cells arrested in G(2)/M phase compared with solvent (P0.05).Conclusion:
Taraxerol has inhibitory effects on AGS cell growth through inducing G(2)/M arrest and promotion of cell apoptosis. Taraxeryl acetate has less effect on cell cycle arrest and apoptosis of AGS cells than taraxerol.
