TITLE: Effects of Forsythia suspensa ethanol extract on the proliferation,migration and invasion of lung cancer cells NCI-H226
摘要: 目的 探究连翘醇提物对肺癌NCI-H226细胞增殖、迁移、侵袭的影响。方法以肺癌NCI-H226细胞为研究对象,将细胞分为对照组,连翘醇提物低、中、高浓度组(5、10、20mg/mL),激活剂组[10mg/mL连翘醇提物+0.5μmol/L核因子κB(NF-κB)信号通路激活剂PMA],抑制剂组(10mg/mL连翘醇提物+10μmol/LNF-κB信号通路抑制剂BAY11-7082),阳性对照组(20μg/mL顺铂),除对照组细胞不作干预外,其余各组细胞加入相应药物培养24h。检测细胞增殖、迁移、侵袭情况,并计算增殖率、迁移率、侵袭细胞数;检测细胞中NF-κBp65、NF-κB抑制蛋白α(IκBα)、磷酸化NF-κBp65(p-NF-κBp65)、磷酸化IκBα(p-IκBα)蛋白表达水平。结果与对照组比较,连翘醇提物各浓度组和阳性对照组细胞的增殖率、迁移率、侵袭细胞数以及细胞中p-IκBα、p-NF-κBp65蛋白表达水平均显著降低(P<0.05);与连翘醇提物中浓度组比较,抑制剂组细胞增殖率、迁移率、侵袭细胞数及细胞中上述蛋白表达水平均显著降低(P<0.05),而激活剂组均显著升高(P<0.05)。结论连翘醇提物可抑制肺癌NCI-H226细胞增殖、迁移和侵袭,其作用机制可能与抑制NF-κB信号通路有关。
ABSTRACT: OBJECTIVE To investigate the effects of Forsythia suspensa ethanol extract on the proliferation, migration and invasion of lung cancer cells NCI-H226. METHODS As research objects, lung cancer cells NCI-H226 were divided into control group, F. suspensa ethanol extract low-, medium- and high-concentration groups (5, 10, 20 mg/mL), activator group [10 mg/mL F. suspensa ethanol extract+0.5 μmol/L nuclear factor kappa B (NF-κB) signaling pathway activator PMA], inhibitor group (10 mg/mL F. suspensa ethanol extract+10 μmol/L NF-κB signaling pathway inhibitor BAY 11-7082) and positive control group (20 μg/mL cisplatin). Except for the control group of cells without intervention, all other groups of cells were cultured with corresponding drugs for 24 hours; the proliferation, migration and invasion of cells were all detected, and the proliferation rate, migration rate, and the number of invading cells were also calculated; protein expressions of NF-κB p65, NF-κB inhibitory protein α (IκBα), phosphorylated NF-κB p65 (p-NF-κB p65) and phosphorylated IκBα (p-IκBα) were determined. RESULTS Compared with control group, the proliferation rate, migration rate, and the number of invading cells as well as the protein expressions of p- IκBα and p-NF-κB p65 were decreased significantly in F. suspensa ethanol extract groups and positive control group (P<0.05). Compared with F. suspensa ethanol extract medium-concentration group, the proliferation rate, migration rate, and the number of invading cells as well as above protein expressions were all decreased significantly in inhibitor group (P<0.05), while those of activator group were increased significantly (P<0.05). CONCLUSIONS F. suspensa ethanol extract can inhibit the proliferation, migration and invasion of lung cancer cells NCI-H226, and the mechanism of which may be related to the inhibition of NF-κB signaling pathway.
