Abstract:
Objective:To investigate the effect of dexamethasone on the growth and the mechanism of apoptosis in K562 cells.Methods:Treat of different dosages of dexamethasone in K562 cell cultural to observe cell inhibitory rate and cell morphology variation.To detected telomerase activity,Fas expression and NO release.Results:Dexamethasone can inhibit the proliferation of K562 cell,decrease telomerase activity,increase Fas expression and induce apoptosis.But no significant effect on nitric oxide production.Conclusion:Inhibit telomerase activity and increase Fas expression maybe one of mechanism of apoptosis.
