摘要: 为分析去甲基斑蝥素二钠盐对人和小鼠肺癌细胞增殖的抑制作用,体外培养人非小细胞肺癌A549细胞和小鼠肺癌Lewis细胞,用WST-1还原法检测不同浓度去甲斑蝥素(norcantharidin,NCTD)对肿瘤细胞增殖的抑制作用,并用流式细胞术分析细胞周期;免疫印迹技术分析MAPK激酶表达。NCTD抑制A549和Lewis增殖的IC50值分别为13.5和9.5 μmol/L;0、6.25、12.50和25.00 μmol/L NCTD处理24 h,诱导A549细胞G2/M期阻滞率分别为26.30%、29.44%、49.83%和81.35%。结果表明,抑制肿瘤细胞增殖可能是去甲基斑蝥素抗肿瘤作用的分子机制之一。

Abstract: To study the influence and mechanism of norcantharidin(NCTD) on growth of lung cancer cell line A549 and Lewis, the inhibitory rate, cell cycle arrest, mitogen activated protein kinase(MAPK) were detected by wst-1, flow cytometry and immunoblotting technique,respectively. IC50 of NCTD to A549 and Lewis was 13.5 μmol/L and 9.5 μmol/L,respectively. This study showed that the inhibition of NCTD on A549 and Lewis. G2/M phase blocking rate was 26.30%,29.44%,49.83% and 81.35% at 24 h after NCTD treated cells, dose of NCTD was 0,6.25,12.50 and 25.00 μmol/L. The results indicated that one of the major antitumor mechanisms of NCTD may be through inhibiting proliferation.
