RESUMO
Objective:To study the effects of dexamethasone(DEX)on the cytotoxicity and apoptosis of NK-92MI cells and the mechanisms involved.Methods:NK-92MI cells were treated with different doses of DEX.The proliferative rate and cytotoxicity of the NK-92MI cells were detected by MTT colorimetry.The cell apoptotic rate was observed by flow cytometry with Annexin V and propidium iodide(PI)double staining.The expression of apoptosis-related gene,Bcl-2 and Bax was detected by RT-PCR.Results:After treated with 1?10-8mol/L to 1?10-3mol/L of DEX for 24 h,48 h and 72 h,the proliferation of NK-92MI cells was significant inhibited(P
