摘要: 目的:探讨肉桂醛对HL-60细胞的增殖及凋亡的影响。方法:采用台盼蓝细胞计数和四甲基偶氮唑蓝(MTT)法研究肉桂醛对HL-60细胞增殖的抑制作用;采用流失细胞仪(FCM)、荧光显微镜(FM)、扫描电镜(SEM)以及透射电镜(TEM)探讨肉桂醛对HL-60细胞的诱导凋亡作用。结果:台盼蓝细胞计数和MTT法结果表明:肉桂醛对HL-60细胞的增殖有明显抑制作用,抑制作用与肉桂醛质量浓度及作用时间呈依赖关系,其半数致死质量浓度为34.87μg/mL;流式细胞仪检测结果表明:肉桂醛(终质量浓度20μg/mL)作用16h后,HL-60细胞早期凋亡比例为32.6%;该组细胞在荧光显微镜、扫描电镜以及透射电镜观察下均呈现早期凋亡特征。结论:肉桂醛能抑制HL-60细胞增殖并促进其凋亡。

Abstract: Objective: To determine the proliferation inhibitory and apoptosis-inducing effects of cinnamaldehyde on HL-60 cells. Methods: The proliferation inhibitory effect was evaluated using trypan-blue staining and MTT assay, and the apoptosis-inducing effect using flow cytometry, scanning electron microscope (SEM) and transmission electron microscope (TEM). Results: Cinnamaldehyde had an oblivious inhibitory effect on the proliferation of HL-60 cells with dependence upon its concentration and treatment time and the LC50, median lethal concentration was 34.87 μg/mL. The rate of apoptosis in HL-60 cells was 32.6 % after being treated with cinnamaldehyde at the dose of 20 μg/mL. for 16 h. Typical apoptotic morphological changes in the cells was observed under fluorescence microscopy, SEM and TEM. Conclusion: cinnamaldehyde cna notably inhibit the proliferation and induce the apoptosis of HL-60 cells.
