Effects of asiatic acid on the expression of mRNA of smad7 and PPARγ in HSC-T6 in vitro

  • 摘要: 目的检测积雪草酸对HSC-T6细胞Smad-7和PPARγ的mRNA表达的影响,探讨积雪草酸抗肝纤维化的分子生物学机制。方法用MTT实验检测积雪草酸对HSC-T6细胞的增殖抑制作用,计算抑制率,确定积雪草酸作用浓度;设置空白对照组与积雪草酸干预组,用半定量RT-RCR检测两组HSC-T6细胞Smad7和PPARγ的mRNA表达差异。结果积雪草酸抑制HSC-T6细胞的增殖,药物浓度为10、20、30、40、50、70、90μmol/L时,抑制率分别为7.47%、12.42%、13.97%、21.32%、47.31%、51.18%、60.36%。空白对照组和积雪草酸干预组的半定量RT-PCR的结果分别为:Smad7/GAPDH mRNA空白对照组为0.267±0.037,积雪草酸干预组为0.358±0.035;PPARγ/GAPDH mRNA空白对照组为0.157±0.054,积雪草酸干预组为0.570±0.066。两组结果间比较差异具有统计学意义,P<0.05。结论积雪草酸可以上调HSC-T6细胞Smad7和PPARγ的mRNA的表达,从而抑制HSC-T6细胞合成和分泌胶原,改善肝...
