摘要: 目的:探讨灵芝酸A在体外对人炎性乳腺癌SUM149细胞增殖和凋亡的影响,阐明其可能机制。方法:人炎性乳腺癌SUM149细胞分为对照组和不同浓度(0.1、0.5、1.0、5.0和10.0 μmol·L-1)灵芝酸A组,每组设4个复孔,分别于培养24、48和72h取样本。MTT法检测各组SUM149细胞增殖抑制率,流式细胞术检测各组SUM149细胞凋亡率和细胞周期,免疫细胞化学染色法检测各组SUM149细胞Ki67和Livin蛋白表达水平。结果:MTT法检测,与0.1μmol·L-1灵芝酸A组比较,其他浓度灵芝酸A组SUM149细胞增殖抑制率明显升高(P<0.05或P<0.01),并呈浓度和时间依赖性。流式细胞术检测,与对照组比较,不同浓度灵芝酸A组SUM149细胞凋亡率明显升高(P<0.05或P<0.01),并呈浓度和时间依赖性;同时细胞周期发生明显变化,与对照组比较,随着灵芝酸A浓度的增加和作用时间的延长,不同浓度灵芝酸A组G1期细胞百分率明显增加(P<0.05),S期细胞百分率减少(P<0.05或P<0.01)。与对照组比较,不同浓度灵芝酸A组细胞中Ki67和Livin蛋白表达水平降低(P<0.05或P<0.01)。结论:灵芝酸A通过诱导细胞凋亡抑制人炎性乳腺癌SUM149细胞增殖。

Abstract: Objective: To study the effects of ganoderma lucidum A on the proliferation and apoptosis of human inflammatory breast cancer SUM149 cells in vitro,and to clarify their mechanisms. Methods: The human inflammatory breast cancer SUM149 cells were divided into control group and different concentrations (0.1,0.5,1.0,5.0 and 10.0 μmol·L-1) of ganoderma lucidum A groups; four holes were set up,and the samples were taken at 24,48 and 72 h after culture.MTT assay was used to detect the inhibitory rate of proliferation of SUM149 cells.Flow cytometry was used to detect the apoptotic rate and cell cycle of SUM149 cells.The expression levels of Ki67 and Livin proteins in SUM149 cells were detected by immunocytochemical staining. Results: Compared with 0.1 μmol·L-1 ganoderma lucidum A group,the inhibitory rates of proliferation of SUM149 cells in other concentrations of ganoderma lucidum A groups were significantly increased detectde by MTT method (P<0.05 or P<0.01) in a concentration-and time-dependent manner.The flow cytometry results showed that the apoptotic rates of SUM149 cells in different conventrations of ganoderma lucidum A groups were significantly higher than that in control group (P<0.05 or P<0.01) in a concentration-and time-dependent manner;at the same time,the cell cycle changed significantly.With the increase of ganoderma lucidum A of the concentration of ganoderma lucidum A,the pencentages of cells at G1 phase in different concentrations of ganoderma lucidum A groups were increased(P<0.05),and the percentages of cells at S phase were decreased compared with control group(P<0.05 or P<0.01).The expression levels of Ki67 and Livin proteins in different concentrations of ganoderma lucidum A groups were decreased compared with control group (P<0.05). Conclusion: Ganoderma lucidum A can inhibit the proliferation of human inflammatory breast cancer SUM149 cells through induction of apoptosis.

Key words: human inflammatory breast cancer cells, ganoderma lucidum A, cell proliferation, apoptosis
