摘要
目的克隆出大鼠结缔组织生长因子(connective tissue growth factor, CTGF)的部分cDNA序列,并观察在实验性肝纤维化大鼠肝脏中 CTGF mRNA的表达改变。方法根据小鼠CTGF mRNA序列设计引物,用 RT-PCR从大鼠肝脏总 RNA中扩增出一段 430 bp的产物,并测定其序列。将 16只雌性 Wistar大鼠随机分为胆管堵塞组(n=8)及假手术组(n=8)。6周后取大鼠肝脏提取总RNA,利用多探针以核酸酶保护分析法测定CTGF及TGFβ1的mRNA水平。结果克隆出的大鼠CTGF cDNA序列在核酸水平与小鼠的同源性为95%。胆汁性肝硬化大鼠肝脏中 TGF β1及 CTGF的 IRNA水平分别为假手术组大鼠的 4倍和 7倍。结论在实验性肝纤维化大鼠肝脏中CTGF mRNA的表达水平明显上调。
