中文摘要:
      摘 要:[目的] 评估马钱子碱对非小细胞肺癌A549细胞的增殖、侵袭和迁移的影响,并探讨其增强化疗敏感性。[方法] 采用NSCLC细胞系A549为研究对象,分别采用CCK-8法、集落形成实验和细胞侵袭、迁移实验检测马钱子碱对A549细胞活力、侵袭和迁移的影响;应用Western blot检测马钱子碱对PTEN、Akt和p-Akt蛋白表达影响。[结果] 马钱子碱或顺铂单独有效抑制细胞生长、细胞集落的发育以及细胞的侵袭和迁移(P<0.05),并且马钱子碱和DDP联合处理对细胞的抑制作用强于单独的化合物(P<0.05)。Western blot分析结果显示,在A549细胞中,马钱子碱(20μg/ml)处理增加PTEN蛋白的表达(P<0.05)减少了p-Akt蛋白表达(P<0.05),并且hsa-miR-21 minic可部分抑制马钱子碱对PTEN蛋白表达的促进作用。[结论] 马钱子碱可抑制肺癌的进展,增强抗癌药物顺铂对肺癌细胞的作用。
英文摘要:
      Abstract:[Objective] To investigate the effect of brucine on proliferation,invasion,migration and sensitivity to cisplatin of non-small cell lung cancer(NSCLC) A549 cells. [Methods] NSCLC A549 cells were treated with brucine(20μg/ml),DDP(6μM)or brucine(20μg/ml) +DDP(6μM) for 12,24,48,72 and 96h. CCK-8 method,colony formation assay,transwell assays were used to determine the proliferation invasion and migration of A549 cells,respectively. Western blot was used to detect the expression of PTEN,Akt and p-Akt proteins in A549 cells. [Results] Brucine or DDP alone inhibited cell growth,colony development,cell invasion and migration(P<0.05),and brucine combined with DDP resulted in stronger cell growth inhibition than single agents(P<0.05). Western blot analysis showed that brucine significantly increased PTEN protein expression(P<0.05) and decreased p-Akt protein expression(P<0.05) in A549 cells. And hsa-miR-21 mimics could partially inhibit the effect of brucine on PTEN protein expression. [Conclusion] Brucine can inhibit cell proliferation and enhance the effects of cisplatin in NSCLC A549 cells.
