目的:研究青蒿素类衍生物蒿甲醚(ARE)对小鼠 Lewis 肺癌细胞株(LLC)体外生长和侵袭的影响,探讨其可能的作用机制。方法采用 MTT 法观察 ARE 对 LLC 细胞生长的抑制效应。Trans-well 侵袭实验检测对照组、ARE 组、GW9662[过氧化物酶体增殖物激活受体γ(PPARγ)特异性抑制剂]组和 GW9662+ARE 组4组LLC 细胞的侵袭力。实时 PCR 和 Western blotting 法检测4组细胞 PPARγ、NF-κB p65、Caspase-3 mRNA 和蛋白表达。结果ARE 呈时间和剂量依赖性方式抑制 LLC 细胞生长,24、48、72 h ARE 对 LLC 的 IC50值分别为271.29、189.08、65.99μg/ml。4组中 ARE 组的荧光值最低,为1744.67,对照组为6887.00,GW9662+ARE 组为4597.00,GW9662组为10012.67,表明 ARE 组侵袭力最弱,而且相比对照组侵袭力明显减弱(t =12.411,P =0.000)。ARE 组、GW9662组 PPARγmRNA 相对表达量分别为2.276±0.534和0.362±0.206,与对照组相比差异均有统计学意义(t =4.785,P =0.001;t =2.395,P =0.044);ARE 组 PPARγ蛋白表达量为27688.33±3593.06,比对照组(17716.33±2273.95)、GW9662+ARE 组(21816.00±1644.07)高(t =5.159,P =0.001;t =3.038,P =0.016)。NF-κB p65 mRNA 表达量在 GW9662+ARE 组(0.346±0.149)最低,其次为 ARE 组(0.392±0.187), GW9662组最高(1.720±0.338),ARE 组与对照组和 GW9662组相比差异有统计学意义(t =3.592,P =0.007;t =7.851,P =0.000)。Caspase-3 mRNA 和蛋白在各组的表达差异没有统计学意义(F =1.181, P =0.376;F =0.647,P >0.05)。结论蒿甲醚可以通过上调 PPARγ表达抑制 NF-κB 的途径来抑制 LLC细胞体外增殖和侵袭,提示 PPARγ可能为肺癌治疗提供一个新的靶点。

mRNA in ARE and GW9662 group were 2.276 ±0.534 and 0.362 ±0.026,respectively.Compared with control group,PPARγmRNA level in both of ARE and GW9662 group reached statistical significance (t =4.785,P =0.001 ;t =2.395,P =0.044).PPARγprotein expression in ARE group,GW9662 +ARE group and control group were 27 688.33 ±3 593.06,21 816.00 ±1 644.07,17 716.33 ±2 273.95,respectively,which was higher in ARE group than that in control and GW+ARE group (t =5.159,P =0.001 ;t =3.038,P =0.016). NF-κB p65 mRNA expression in GW9662 +ARE group was 0.346 ±0.149,which in ARE group and GW9662 group were 0.392 ±0.1 87 and 1 .720 ±0.338,respec-tively.The differences of NF-κB p65 mRNA expression level between ARE,and control or GW9662 group were statistically significant (t =3.592,P =0.007;t =7.851 ,P =0.000).While,the differences of Caspase-3 mRNA and protein expression levels among the four groups were not statistically significant (F =1 .1 81 ,P =0.376;F =0.647,P >0.05).Conclusion ARE may restrain NF-κB through up-regulating PPARγto inhibit the proliferation and invasive potential of LLC in vitro, which suggests that PPAR-γmay be a novel therapeutic target for lung cancer.
