摘要 目的:研究青蒿琥酯对人肺成纤维细胞(HFL-I)的TGF-β1/smad通路及其对细胞增殖的影响。方法:使用青蒿琥酯和重组人TGF-β1刺激因子的干预下对HFL-I在体外培养,然后Western bloting(WB)检测TGF-β1、Smad3和Smad7蛋白的表达;并使用流式细胞仪检测细胞周期。结果:青蒿琥酯可抑制TGF-β1及Smad3蛋白的表达(P<0.05),刺激Smad7的磷酸化蛋白的表达(P<0.05);对Smad3非磷酸化蛋白无影响;对青蒿琥酯处理的HELF细胞使用重组人TGF-β1刺激因子可使TGF-β1蛋白的表达升高(P<0.05),磷酸化的Smad3蛋白的表达升高(P<0.05)。HELF细胞经过青蒿琥酯处理后细胞主要停滞于G1期,经过重组人TGF-β1刺激因子处理的细胞主要分布于S期。结论:青蒿琥酯可以通过TGF-β1/smad通路对HFL-I有抑制的作用,抑制的细胞停滞在细胞周期的G1期。
