摘要 目的:观察重组人肝再生增强因子(recombinant humanaugmenter of liver regeneration,rhALR)对梗阻性黄疸大鼠肝细胞线粒体转录因子A(mitochondrial transcription factor A,TFAM)及核呼吸因子1(nuclear respiratory factor-1,NRF-1)表达的影响。方法:健康Wistar大鼠随机分为假手术(Sham)组、胆道梗阻再通(BDO-RBF)组、胆道梗阻再通及rhALR治疗(BDO-RBF-rhALR)组(n=48),利用荧光定量PCR方法检测各组大鼠肝细胞TFAM、NRF-1mRNA的表达。结果:当胆道梗阻后,大鼠肝细胞TFAM、NRF-1mRNA表达均下降(P<0.05),且随着梗阻时间的延长其下降程度逐步增加;解除梗阻后,其拷贝数逐步恢复。BDO-RBF-rhALR组大鼠TFAM、NRF-1mRNA表达明显高于同一时间点BDO-RBF组(P<0.05)。结论:腹腔注射rhALR可能通过促进梗阻性黄疸大鼠肝细胞TFAM、NRF-1mRNA表达发挥保护肝功能的作用。
