发布时间:2018-12-29 11:33
【摘要】: 目的:克隆鼠IFN-λ2基因,构建其腺病毒载体,获取病毒重组子,并研究其生物学活性。 方法:用人水疱口炎病毒VSV(vesicular stomatovirus)病毒诱导小鼠原代脾细胞表达IFN-λ2,通过RT-PCR获取IFN-λ2 cDNA,将其亚克隆至pShuttle-CMV载体,经PmeⅠ线性化后,与腺病毒的骨架载体pAdEasy在BJ5183菌中同源重组,293A细胞包装扩增,免疫荧光、Western blot检测mIFN-λ2蛋白的表达。mIFN-λ2对鼠肺腺癌细胞LA795的抑制作用,通过MTT细胞存活实验检测活性。 结果:获取鼠IFN-λ2的cDNA,序列与GeneBank公布序列完全一致,成功构建腺病毒载体;MTT法研究Ad-mIFN-λ2和Ad-Lacz对小鼠肺腺癌细胞LA795的体外抑制作用,结果显示mIFN-λ2对LA795细胞生长具有一定的抑制作用。 结论:成功构建mIFN-λ2的重组腺病毒载体,其病毒重组子体外具有生物活性。
