摘要
目的:旨在探讨β-榄香烯对人胃癌BGC823细胞Akt通路的活化和凋亡相关蛋白Bax、Bcl-2和PARP表达的影响。方法:实验分为对照组和β-榄香烯处理组,采用四甲基偶氮唑盐(MTT)试验法检测β-榄香烯对人胃癌BGC823细胞的药物敏感性,采用Western blot检测蛋白表达,应用SPSS(13.0软件包)进行统计学分析。结果:β-榄香烯处理胃癌BGC823细胞24h的IC50为46.56μg/ml,选用50μg/ml和200μg/ml的β-榄香烯处理24h,BGC823细胞凋亡率分别为12.33%和42.59%,与对照组相比有统计学差异(P<0.05)。与对照组相比,β-榄香烯处理组Bcl-2与Bax的比值显著下调、伴有PARP裂解。进一步检测发现β-榄香烯处理组明显下调了Akt的磷酸化水平,从而有效抑制Akt信号转导通路。结论:β-榄香烯可以通过抑制Akt信号通路的活化、下调Bcl-2与Bax的比值和诱导PARP裂解,进而抑制胃癌细胞增殖和诱导细胞凋亡。
