摘要:
研究乙酰氧基胡椒酚乙酸酯(ACA)对人乳癌MCF7细胞增殖及凋亡的影响及其作用机制。方法：应用MTT法检测ACA对人乳癌MCF7细胞的增殖抑制作用，观察细胞形态学改变，流式细胞仪分析细胞周期及凋亡率，免疫细胞化学法检测Bcl2、Bax蛋白的表达。结果：ACA剂量依赖性地抑制MCF7细胞增殖，其24h的IC50为(108.57±5.85)μmol/L。100、150μmol/LACA作用后MCF7细胞出现典型的凋亡形态学特征，包括核浓缩致密，细胞皱缩。ACA对MCF7细胞周期分布无明显影响，而终浓度为100、150μmol/L时，出现亚Gl峰。50、100、150μmol/LACA作用后MCF7细胞的Bcl2蛋白表达减少,Bax蛋白表达增加，与对照组比较，差异有统计学意义(P<0.05)。结论：ACA能明显抑制MCF7细胞的增殖，并可通过下调Bcl2和上调Bax蛋白表达诱导其凋亡。
Abstract:
To study the effects and mechanism of 1’acetoxychavicol acetates(ACA) on the proliferation and apoptosis of breast carcinoma cell line MCF7.Methods:Antiproliferative effect of ACA against MCF7 was tested by MTT assay，morphological changes of MCF7 cells were observed by light microscopy,and cell apoptosis percentage and cell cycle phase distribution of MCF7 were measured by flow cytometric assay.The expressions of apoptosisrelated proteins Bcl2 and Bax were determined by immunocytochemical method.Results:A dosedependent proliferation inhibition was demonstrated in ACA and the IC50 for 24 h on MCF7 cells was (108.57 ±5.85) μmol/L. The characteristic morphological changes of apoptosis were observed in cells after treated with ACA，including cell shrinkage and chromatin condensation. There were no significant differences in the percentage of cells treated with ACA in G0/G1,S or G2/M. However, subG1 peak was observed in both the 100 μmol/L and 150 μmol/L treatment groups. With the treatment of ACA，the protein expression of Bcl2 decreased while Bax increased.Conclusion: ACA exhibits the potent proliferation inhibition and apoptosis induction on MCF7 cells, which might be related to the downregulation of Bcl2 expression and upregulation of Bax.
