| 摘 要： | 目的:研究重组真核载体PcDNA3.l-MxA体外抗HBV的作用,为研究MxA基因(myxovirus-resistant A)治疗慢性HBV感染奠定基础.方法:将构建成功的重组真核载体PcDNA3.l-MxA转染入HepG 2.2.15.将HepG 2.2.15分为实验组(转染PcDNA3.1-MxA的HepG 2.2.15)和对照组(转染PcDNA3.1的HepG 2.2.15),应用RT-PCR方法检测两组HepG2.2.15内MxAmRNA(P<0.01),并应用ELISA法检测两组HepG2.2.15内HBsAg、HBeAg的水平.结果:RT-PCR扩增结果显示实验组的MxAmRNA水平均较对照组明显升高,实验组HBsAg、HBeAg水平明显低于对照组(均P<0.01).结论:转染重组真核载体PcDNA3.l-MxA HepG2.2.15内MxA蛋白明显抑制了HBV DNA的复制及表达,为进一步研究MxA蛋白体内抗病毒作用提供理论.
