摘要
目的:构建大鼠野生型肿瘤坏死因子受体相关因子6(tumor necrosis factor receptor-associated factor 6,TRAF6)基因及其特异性短发卡状小干涉RNA(shRNA)真核表达质粒,并观察其在大鼠肾小球系膜细胞(GMC)中过表达和沉默TRAF6基因的情况。方法:用DNA重组技术将针对大鼠TRAF6基因的CDS区序列(加HA标签)和针对其不同位点所设计的3种shRNA序列分别克隆到pcDNA3.1及pGenesil-1/GFP真核表达质粒中。在酶切鉴定及序列测定正确后,用NeonTM电转仪,将上述质粒分别转染入培养的大鼠GMC中,然后用Western blot检查HA-TRAF6融合蛋白的表达情况,同时筛选最有效的TRAF6shRNA。结果:限制性酶切及核酸序列分析确证,上述TRAF6基因过表达和shRNA表达质粒均构建成功。Western blot显示,构建的pcDNA3.1-HA-TRAF6质粒能在大鼠GMC中表达,且TRAF6 shRNA-1具有最佳的沉默效率。结论:本实验成功构建了大鼠野生型TRAF6真核表达质粒及其特异性的shRNA表达载体,这为今后进一步研究TRAF6基因的生物学功能提供了实验基础。
