          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-
