    • An analysis system for measuring a Smad activation by a TGF-beta is provided to simplify the experiment process and measure a small amount of sample. A Smad activation-dependent reporter gene expression vector comprises (i) a nucleic acid molecule having DNA sequence which Smad transcription factor is connected to, (ii) a luciferase gene connected to 3'-terminal of the nucleic acid molecule, (iii) an antibiotics-resistant gene as a selection probe. The antibiotics-resistant gene is hygromycine resistant gene. A method for measuring the activation or amount of Smad transcription factor or TGF- beta comprises: a step of treating TGF- beta inhibitor or activator into a transfected cell line; and a step of measuring the luciferase activation of the treated cell line; A method for screening an anticancer drug, anti-inflammatory drug or anti-fibrosis drug comprises: a step of treating the TGF- beta inhibitor or activator into the transfected cell line; and a step of comparing the luciferase activations between the transfected cell line and the control cell.
    • 提供了一种用于测量TGF-β的Smad活化的分析系统,以简化实验过程并测量少量样品。 Smad活化依赖性报告基因表达载体包含(i)具有与Smad转录因子连接的DNA序列的核酸分子,(ii)与核酸分子的3'-末端相连的荧光素酶基因,(iii) 抗生素抗性基因作为选择探针。 抗生素抗性基因是抗潮霉素基因。 用于测量Smad转录因子或TGF-β的活化或量的方法包括:将TGF-β抑制剂或活化剂处理到转染的细胞系中的步骤; 以及测量经处理的细胞系的荧光素酶活化的步骤; 用于筛选抗癌药物,抗炎药或抗纤维化药物的方法包括:将TGF-β抑制剂或活化剂处理至转染的细胞系中的步骤; 以及比较转染细胞系和对照细胞之间荧光素酶活化的步骤。
