Abstract目的:非小细胞肺癌是世界范围内最常见且致死率最高的恶性肿瘤之一,迫切需要寻找新的有效治疗药物。本研究主要探讨竹柏来源天然产物PNE6C对非小细胞肺癌的抗肿瘤作用及其机制。 方法:以MTT和克隆形成实验检测PNE6C对A549细胞增殖能力的影响。流式细胞术和Western Blot检测PNE6C对A549细胞周期与凋亡的影响及相关蛋白表达的变化。 结果:PNE6C 能够显著抑制A549细胞增殖,半数抑制浓度为1.90±1.25 μM。PNE6C预处理24 h能够显著抑制A549细胞克隆形成。细胞周期检测结果显示,PNE6C处理24 h能够引起细胞G2期周期阻滞。进一步实验发现,PNE6C下调Cyclin B1、磷酸化cdc2 (Tyr15) 和cdc25C (Ser216) 以及Wee1的蛋白表达水平, 表明PNE6C可能抑制了Cyclin B1/cdc2的复合物活性而引起G2期周期阻滞。PNE6C处理A549细胞48 h可诱导其凋亡。随着PNE6C浓度的升高,Annexin V 阳性细胞增加,PARP切割增多。 结论:PNE6C抑制A549细胞增殖,诱导细胞G2期阻滞与凋亡,对非小细胞肺癌具有潜在的治疗作用。
