摘    要:目的 :了解乙型肝炎病毒DNA序列在乙型肝炎病毒转基因小鼠中的整合情况。方法 :用头尾相接的乙型肝炎病毒全序列基因 ,通过原核显微注射法产生转基因小鼠 ,用C区特异性引物扩增鼠尾DNA检测整合 ,对其中 10只阳性鼠的扩增产物测序。结果 :12 8只仔鼠中 ,14只整合阳性。对 10只阳性鼠测序 ,9只与所转基因序列完全相同 ,1只在173 9、1740位缺失两个碱基。结论 :外源乙型肝炎病毒基因确实整合至小鼠基因组 ,多数为正常整合 ,但也存在缺失整合。

关 键 词:转基因小鼠  乙型肝炎病毒  整合

Abstract:Objective:To investigate the integration of exogenous DNA in hepatitis B Virus (HBV) transgenic mice. Methods:Transgenic mice carrying HBV gene were generated by means of pronucleus injection. Using HBV Core gene primer to amplify tail tissue DNA, the PCR pruducts of 10 positive transgenic mice were sequenced. Results:14 out of 128 offsprings were HBV positive,9 out of the 10 positive mice had the same sequence as the injected HBV DNA,while one transgenic mice had 2 nucleotide (nt) deletions in 1739nt and 1740nt.Conclusions:It was showed that exogenous HBV DNA had integration into mice genome.
Keywords:Transgenic mice  HBV  Integration
