Establishment of BEAS-2B stable cell lines with lentiviral-based hsa-miR-100-3p inhibitor

  • 摘要: 目的 建立稳定感染人hsa-miR-100-3p抑制剂慢病毒表达载体的人支气管上皮(human bronchial epithelial,BEAS-2B)细胞株,为研究miR-100的功能奠定基础。方法 根据hsa-miR-100-3p的成熟序列,设计其反向互补序列,用聚合酶链式反应(polymerase chain reaction,PCR) 的方法扩增目的基因,将目的基因与慢病毒载体GV280经双酶切后,进行定向连接,产生GV280-hsa-miR-100-3p-inhibitor慢病毒表达载体。将制备好的重组慢病毒质粒与两种辅助包装原件载体质粒共转染人胚肾上皮细胞293(human embryo kidney epithelial cell,HEK-293)T细胞,包装产生病毒颗粒并以最适滴度感染BEAS-2B细胞以获得稳定感染的细胞株。倒置荧光显微镜观察感染效率,用逆转录聚合酶链式反应(reverse transcription-polymerase chain reaction,RT-PCR)的方法检测重组慢病毒感染后BEAS-2B细胞中miR-100的相对表达量。结果 测序结果表明,目的基因成功的连接到慢病毒载体上,重组慢病毒高效的感染了BEAS-2B细胞。RT-PCR检测发现,BEAS-2B细胞中miR-100的相对表达明显的下调了。结论 稳定感染hsa-miR-100-3p抑制剂的BEAS-2B细胞株构建成功,敲低了细胞中内源性miR-100的表达。
