摘要
目的研究白屈菜红碱对大鼠肝星状细胞(HSC-T6)的增殖和胶原合成的影响。方法利用MTT法检测乙醛活化的HSC-T6的细胞活力,消化法检测细胞羟脯氨酸(Hyp)含量,ELISA法检测细胞上清液中Ⅰ型胶原蛋白(Col-Ⅰ)和Ⅲ型胶原蛋白(Col-Ⅲ),RT-PCR检测α-平滑肌肌动蛋白(α-SMA)mRNA的表达。结果与正常组比较,模型组HSC-T6的细胞增殖、Hyp含量、Col-Ⅰ和Col-Ⅲ含量较正常对照组均显著升高(P<0.05),α-SMA mRNA表达明显上调(P<0.05)。而与模型组比较,模型+白屈菜红碱(10μg·ml~(-1),20μg·ml~(-1))组HSC-T6的细胞增殖、Hyp含量、Col-Ⅰ和Col-Ⅲ含量显著降低(P<0.05),α-SMA mRNA的表达明显下调(P<0.05)。结论白屈菜红碱抑制大鼠肝星状细胞的增殖和胶原合成。
