英文摘要Aim: To study the effects of actinomycin D (Act D) on the cytotoxicity and apoptosis elicited by salvicine in human leukemia K562 cells. Methods: Growth inhibition of K562 cells was measured by the microculture tetrozolium (MTT) assay. Cell apoptosis was evaluated by fluorescence microscopy, DNA agarose gel electrophoresis, and flow cytometry. Results: Following exposure of K-562 cells to salvicine plus Act D for 24 h, Act D at the concentrations of 0.04, 0.4, and 4 mumol/L potentiated the cytotoxicity of salvicine 6.25 mumol/L to, some degree. The mean growth inhibitory rates went from 8% up to 69%, 71%, and 70%, respectively. However, the same enhancement of Act D did not continue to emerge at the higher concentrations than salvicine 6.25 mumol/L. Act D enhanced, or at least, did not decrease the cytotoxicity of salvicine against K562 cells. Fluorescence microscopy, DNA agarose gel electrophoresis, and flow cytometry revealed that Act D concentration-dependently inhibited the induction of apoptosis by salvicine in the same cell line. Conclusion: The combination of salvicine and Act D in a proper range of concentrations is able to enhance the cytotoxicity of salvicine against K562 cells though inhibiting apoptosis. The other mechanisms of cell death except apoptosis may be implicated in the process.
