摘要:

背景:有研究表明人白细胞抗原-A*0206亚型与鼻咽癌的发生正相关,但目前还没有相应的转基因动物模型,以用于从整体水平评价HLA-A*0206与鼻咽癌的关系及进一步研究免疫和基因疗法。
目的:构建pLVX-CMV-人白细胞抗原-A*0206-HA-mCMV-ZsGreen载体,并进行病毒包装,以用于HLA-A*0206转基因小鼠制作。
方法:合成HLA-A*0206序列,利用聚合酶链式反应在5’端引入Eco RⅠ酶切位点,在3’端引入Bam HⅠ酶切位点和流感病毒血凝素标签,Eco RⅠ和Bam HⅠ双酶切目的片段及pLVX-CMV-mCMV-ZsGreen质粒,连接酶切产物,转化到大肠杆菌JM109感受态细胞,双酶切及测序鉴定阳性重组质粒,阳性重组质粒与四质粒包装系统共转染表达SV40大T抗原的人肾上皮细胞系293T细胞,产生含目的基因的慢病毒。
结果与结论:凝胶电泳及测序证实人白细胞抗原A*0206基因成功导入pLVX-CMV-mCMV-ZsGreen骨架质粒,转染293T细胞48 h后的转染率为92%。荧光法测定病毒滴度,获得病毒滴度约为5×108。结果证实,实验成功构建了含巨细胞病毒启动子、HLA-A*0206、流感病毒血凝素标签以及ZsGreen报告基因的慢病毒。

Abstract:

BACKGROUND: Studies have shown that human leukocyte antigen (HLA)-A*0206 subtype is related to the abscess of nasopharyngeal carcinoma, but there is no corresponding transgenic animal models that could used to judge the relationship between HLA-A*0206 and nasopharyngeal carcinoma on the overall level and further research of immunotherapy and gene therapy.
OBJECTIVE: To construct lentiviral vectors carrying pLVX-CMV-HLA-A*0206-HA-mCMV-ZsGreen and establish HLA-A*0206 transgenic mice.
METHODS: The HLA-A*0206 sequence was synthesized. EcoRI recognition site was introduced in the 5’ end by polymerase chain reaction, and influenza virus hemagglutinin labels and BamHI recognition site were introduced in the 3’ end. Eco RI and Bam HI double enzyme digestion target fragments and the pLVX-CMV-mCMV-ZsGreen plasmids were connected to the digested productions and transfected JM109 competent cells. The positive clones were selected and identified by double enzyme digestion and sequencing. The positive plasmid and packaging plasmids were transfected into 293T cells, which were human renal epithelial cell line that can express SV40 large T antigen. The lentivirus containing target sequence was produced.
RESULTS AND CONCLUSION: Gel electrophoresis and sequencing results showed that, HLA-A*0206 was successfully inserted into pLVX-CMV-mCMV-ZsGreen frame plasmids. Transfection efficiency was 92% after 48 hours of transfecting 293T cells. The viral suspension titer was 5 × 108 measured by fluorescence method. Experimental findings indicate that, the lentivirus containing cytomegalovirus promoter, HLA-A*0206, influenza virus hemagglutinin label and Zsgreen report gene was successfully constructed.
