【摘要】 目的将pcDNA3.1(-)-ALR(hALR)和pcDNA3.1(-)分别转染人肝星形细胞(HSC),筛选在人肝星形细胞中存在表达差异的基因,进一步研究hALR的生物学功能及机制。方法以脂质体技术将pcDNA3.1(-)-ALR和pcDNA3.1(-)分别转染人肝星形细胞系,提取总mRNA,逆转录为cDNA,应用基因表达谱芯片方法分析差异表达的基因。结果在所筛选的4096个基因中,有2个基因表达水平显著上调,25个基因表达水平显著下调。结论 hALR对于人肝星形细胞基因表达谱有显著影响,为进一步研究hALR的生物学功能和作用机制提供了线索。更多还原

【Abstract】 Objective To screening the differential gene expression in human hepatic stellate cells (HSC) treated with pcDNA3.1-ALR in order to investigate the biological functions and mechanism of human augmenter of liver regeneration (hALR). Methods HSC were transfected by pcDNA3.1 (-) and pcDNA3.1- ALR, respectively, using FuGENE6 transfection reagent. The total mRNA was isolated and reverse transcribed to synthesize the cDNA probes. Analyzed the differentially expressed genes by microarray gene expression profiling technique. Results Two genes were up-regulated and 25 genes were down-regulated among detected 4096 genes. Conclusions hALR has marked effect on gene expression profilings of human HSC. These results provide new clues for studying the molecular biological function and mechanism of hALR.更多还原
