摘要:

目的:探索独一味乙醇提取物(ethanol extract of lamiophlomis rotate,EELR)促进人黏液表皮样癌MEC-1细胞凋亡的作用及其机制。方法: 采用磺酰罗丹明B(sulforhodamine B,SRB)比色法测定细胞活力、细胞克隆形成实验检测细胞增殖率、Hoechst33258/PI荧光染色以及流式细胞术检测EELR对MEC-1细胞凋亡率的影响,采用蛋白质免疫印迹试验(Western blot)检测凋亡相关蛋白的表达水平。结果:EELR在一定浓度范围呈时间和剂量依赖性抑制MEC-1细胞增殖,且不同剂量EELR作用于MEC-1细胞48 h后细胞凋亡率有明显差异,Western blot检测表明随EELR作用浓度增加,MEC-1细胞Bcl-2蛋白表达下调,Bax、Casepase-3蛋白表达量升高。 结论:EELR可能通过调节人黏液表皮样癌MEC-1细胞的Bcl-2、Bax、Casepase-3蛋白表达水平进而诱导细胞凋亡。

Abstract:

AIM: To investigate the pro-apoptotic of ethanol extract of Lamiophlomis rotate (EELR) on human mucoepidermoid cancer cells (MEC-1). METHODS: Sulforhodamine B (SRB) colorimetric method, cell clone formation experiment, Hoechst33258/PI staining and flow cytometry instrument technique were used to determine cell apoptosis, and Western blot analysis was used to detect alterations in cell apoptosis pathway-related proteins.RESULTS:EELR dose- and time-dependently exhibited anti-proliferation. With the increase of EELR concentration, the pro-apoptotic effect on MEC-1 was increased gradually. Moreover, Western blot analysis indicated that the expression of Bcl-2 was reduced and Bax and Casepase-3 were increased with the increasing of EELR concentration. CONCLUSION: EELR can induce MEC-1 cells apoptosis, which may be associated with the down-regulation of the Bcl-2 expression and up-regulation of the Bax and Casepase-3 expressions.

Key words: ethanol extract of Lamiophlomis rotate, mucoepidermoid carcinoma MEC-1 cell lines, cell apoptosis
