      摘 要 目的: 研究香芹酚对胃癌BGC-823细胞的生长、凋亡及侵袭的影响。方法: 采用MTT法检测香芹酚对胃癌BGC-823细胞的增殖抑制作用;流式细胞技术检测香芹酚对胃癌BGC-823细胞凋亡的影响;Transwell法检测香芹酚对胃癌BGC-823细胞侵袭能力的影响;实时荧光定量PCR检测MMP-9、TIMP-1的表达;Western blot检测caspase-9、PARP的表达以及ERK、P38信号通路的激活情况。结果:香芹酚能够明显抑制胃癌细胞生长(P<0.05),与对照组相比,香芹酚处理组胃癌BGC-823细胞凋亡明显增加(0 μmol·L-1 vs 10 μmol·L-1,0 μmol·L-1 vs 20 μmol·L-1,0 μmol·L-1 vs 40 μmol·L-1,0 μmol·L-1 vs 80 μmol·L-1),侵袭能力显著降低(0 μmol·L-1 vs 80 μmol·L-1),差异均有统计学意义(P<0.000 1)。香芹酚处理组细胞caspase-9、TIMP-1表达升高(P<0.000 1)、PARP发生裂解(P<0.000 1),P38信号被激活,同时MMP-9表达降低(P<0.000 1),ERK信号通路受到抑制。结论: 香芹酚能够抑制胃癌细胞的增殖和侵袭,诱导其凋亡,其作用与MAPK信号通路激活密切相关。
英文摘要:
      ABSTRACT Objective: To investigate the anti proliferation effect of carvacrol on human gastric cancer cell BGC-823 and explore the molecular mechanism. Methods: The proliferation of BGC-823 cells was evaluated by MTT assay. Flow cytometry was used to analyze the cell apoptosis after exposed to carvacrol. Transwell assay was used to analyze the effect of carvacrol on cell metastasis. Quantitative realtime PCR was used to detect the expression of MMP-9 and TIMP-1. The expression of caspase-9 and PARP, and the activation of ERK and P38 were detected by Western blot. Results: The incubation with carvacrol resulted in a significant inhibition of BGC-823 cell proliferation. After the treatment with carvacrol, the apoptotic rate was significantly increased(0 μmol·L-1 vs 10 μmol·L-1,P<0.000 1;0 μmol·L-1vs 20 μmol·L-1,P<0.000 1;0 μmol·L-1vs 40 μmol·L-1, P<0.000 1;0 μmol·L-1vs80 μmol·L-1, P<0.000 1)and the invasion ability was decreased (0 μmol·L-1vs 80 μmol·L-1, P<0.000 1).The expression of caspase-9(0 μmol·L-1vs80 μmol·L-1,P<0.000 1)and TIMP-1 was increased(P<0.000 1), PRAP fragment occurred (P<0.000 1)and P38 signaling pathway was activated in the carvacrol treated group, while the expression of MMP-9 activity of ERK signaling pathway was inhibited(P<0.000 1).Conclusion: Carvacrol can inhibit cell growth and invasion, and induce cell apoptosis, which is closely related to MAPK signaling pathway.
