摘 要 目的 研究狼毒大戟活性成分17-羟-岩大戟内酯B(HJB)对人三阴性乳腺癌(TNBC)细胞MDA-MB-231、MDA-MB-468
增殖及凋亡的影响。方法 用0(空白对照)、5、10、20、40、80 μmol/L的HJB分别处理MDA-MB-231、MDA-MB-468细胞24、48、72
h,采用MTT法检测各组细胞的增殖抑制率。以0(空白对照)、10、20、40 μmol/L的HJB作用于上述2种细胞24 h后,采用激光共
聚焦显微镜和流式细胞术检测细胞的凋亡情况和线粒体膜电位、活性氧水平的变化情况,并采用Western blot法检测B细胞淋巴
瘤2(Bcl-2)、Bcl-2相关X蛋白(Bax)、细胞色素C(Cyt-C)、胱天蛋白酶3(caspase-3)、活化的caspase-3(cleaved caspase-3)、caspase-
9、cleaved caspase-9蛋白的表达水平。结果 与空白对照相比,5、10、20、40、80 μmol/L的HJB均可显著升高MDA-MB-231、MDA-
MB-468细胞的增殖抑制率(P<0.05),且有浓度和时间依赖趋势。10、20、40 μmol/L的HJB作用24 h后,2种细胞凋亡增多,总凋
亡率均显著升高(P<0.05);线粒体膜电位均显著降低(P<0.05);活性氧水平均显著升高(P<0.05);Bcl-2、caspase-3、caspase-9蛋白
的表达均显著下调(P<0.05),Cyt-C、Bax、cleaved caspase-3、cleaved caspase-9 蛋白的表达均显著上调(P<0.05)。结论 HJB 对
MDA-MB-231、MDA-MB-468细胞的增殖具有抑制作用,并可诱导其凋亡。

ABSTRACT OBJECTIVE To study the effects of the active component 17-hydroxy-jolkinolide B (HJB) of Euphorbia
fischeriana on the proliferation and apoptosis of human triple-negative breast cancers (TNBC) MDA-MB-231 and MDA-MB-468
cells. METHODS MTT assay was adopted to detect the inhibitory rate of MDA-MB-231 and MDA-MB-468 cells proliferation after
treated with 0 (blank control),5,10,20,40,80 μmol/L HJB for 24, 48 and 72 h. Laser confocal microscope and flow cytometry
were adopted to detect the apoptosis, mitochondrial membrane potential(MMP) and reactive oxygen species (ROS) of above 2
kinds of cells after treated with 0 (blank control), 10,20,40 μmol/L HJB for 24 h. Western blot assay was used to detect the
expressions of B cell lymphoma-2 (Bcl-2), Bcl-2-associated X protein (Bax), cytochrome-C (Cyt-C), caspase-3, cleaved caspase-
3, caspase-9 and cleaved caspase-9. RESULTS Compared with blank control group, 5,10,20,40,80 μmol/L HJB could
significantly increase the inhibitory rate of MDA-MB-231 and MDA-MB-468 cells proliferation (P<0.05), in dose- and time-
dependent trend. After 24 h treatment of HJB (10,20,40 μmol/L), the apoptosis of above 2 kinds of cells increased, and the total
apoptotic rate increased significantly (P<0.05); the mitochondrial membrane potential decreased significantly (P<0.05); the level
of ROS increased significantly (P<0.05); the protein expressions of Bcl-2, caspase-3 and caspase-9 were decreased significantly (P<
0.05), while the protein expressions of Cyt-C, Bax, cleaved caspase-3 and cleaved caspase-9 were increased significantly (P<0.05).
CONCLUSIONS HJB can inhibit the proliferation of MDA-MB-
