Keyword:  湿生扁蕾(口山)酮肠纤维化上皮间质转化链霉菌抗生物素蛋白-过氧化物酶法实时荧光定量聚合酶链反应;
Abstract: 目的 探讨湿生扁蕾酮对溃疡性结肠炎(UC)肠纤维化大鼠肠上皮细胞间质转化的影响.方法 通过2,4,6-三硝基苯磺酸(TNBS)诱导大鼠溃疡性结肠炎肠纤维化模型,利用湿生扁蕾酮干预溃疡性结肠炎肠纤维化模型大鼠,采用链霉菌抗生物素蛋白-过氧化物酶(S-P)法检测上皮表型标记蛋白E-钙黏蛋白(E-cadherin)和间质表型标记蛋白α-平滑肌肌动蛋白(α-SMA)的表达情况,采用实时荧光定量聚合酶链反应(qRT-PCR)法检测E-钙黏蛋白、α-平滑肌肌动蛋白mRNA的表达情况.结果 与模型组相比,湿生扁蕾酮显著增加溃疡性结肠炎肠纤维化大鼠肠上皮细胞E-钙黏蛋白的表达,抑制α-平滑肌肌动蛋白的表达.结论 湿生扁蕾酮可通过抑制结肠上皮细胞间质转化作用,明显改善2,4,6-三硝基苯磺酸诱导的大鼠溃疡性结肠炎肠纤维化.
