摘 要 目的 研究过氧化麦角甾醇衍生物EP-3P对人三阴性乳腺癌细胞MDA-MB-231增殖、迁移和侵袭的影响,为乳腺癌治疗
相关药物的开发提供参考。方法 采用MTT法检测0(空白对照)、1.25、2.5、5、10、20、40 μmol/L EP-3P作用于MDA-MB-231细胞
24、48、72 h后细胞的增殖情况。以0(空白对照)、5、10、20 μmol/L EP-3P作用于MDA-MB-231细胞24 h后,分别采用细胞划痕法、
Transwell小室法检测细胞迁移和侵袭能力,采用流式细胞术分别测定细胞凋亡和周期分布情况,并采用Western blot法检测细胞
中 B 淋巴细胞瘤 2(Bcl-2)、Bcl-2 相关 X 蛋白(Bax)、胱天蛋白酶 3(caspase-3)、活化的 caspase-3(cleaved-caspase-3)、细胞色素 C
(Cyt-C)、基质金属蛋白酶2(MMP-2)、MMP-9蛋白的表达水平。结果 与空白对照比较,2.5、5、10、20、40 μmol/L EP-3P均可显著
升高细胞的增殖抑制率(P<0.05或P<0.01),且呈浓度和时间依赖趋势。10、20 μmol/L EP-3P作用24 h后,均可显著降低/减少细
胞迁移愈合率和侵袭细胞数(P<0.01),将细胞周期阻滞于G2/M期(P<0.05或P<0.01),显著升高细胞的凋亡率(P<0.05),并且
可显著上调细胞中 Bax、Cyt-C、cleaved-caspase-3 蛋白表达和下调细胞中 Bcl-2、caspase-3、MMP-2、MMP-9 蛋白表达(P<0.01)。
结论 EP-3P可通过线粒体介导的内源性caspase途径抑制人乳腺癌细胞MDA-MB-231的增殖、迁移和侵袭,并可诱导细胞发生凋亡。

ABSTRACT OBJECTIVE To study the effects of ergosterol peroxide derivatives EP-3P on the proliferation,migration and
invasion of human tripe negative breast cancer cell MDA-MB-231,and to provide reference for the development of breast cancer
related drugs. METHODS MTT assay was adopted to detect the proliferation of MDA-MB-231 cells after treated with 0(blank
control),1.25,2.5,5,10,20,40 μmol/L EP-3P for 24,48 and 72 h. Wound healing assay and Transwell chamber method were
adopted to detect the migration and invasion ability of MDA-MB-231 cells after treated with 0(blank control),5,10,20 EP-3P for
24 h. The apoptosis and cell cycle distribution were detected by flow cytometry. Western blot assay was used to detect the
expressions of B-cell lymphoma-2 (Bcl-2),Bcl-2 associated X protein (Bax),caspase-3,cleaved-caspase-3,cytochrome C
(Cyt-C),matrix metalloproteinase-2(MMP-2)and MMP-9. RESULTS Compared with blank control group,2.5,5,10,20,40
μmol/L EP-3P could significantly increase the inhibitory rate of cell proliferation(P<0.05 or P<0.01)in a dose and time-
dependent manner. After 24 h treatment of EP-3P(10,20 μmol/L),the rate of cell migration and the number of invasive cells
were decreased significantly (P<0.01),and cell was arrested at G2/M stage (P<0.05 or P<0.01);the apoptotic rate was
increased significantly(P<0.05);the protein expressions of Bax,Cyt-C and cleaved-caspase-3 were upregulated significantly,
while those of Bcl-2,caspase-3,MMP-2 and MMP-9 were downregulated significantly (P<0.01). CONCLUSIONS EP-3P can
inhibit the proliferation,migration and invasion of human tripe negative breast cancer cells MDA-MB-231 through mitochondrial
mediated endogenous caspase pathway,and induce the apoptosis of cells.
