Expression of small hairpin RNA (shRNA) in mammalian cells can trigger potent RNAi-mediated gene silencing. The dominant-acting RNAi can often result in phenotypes similar to that of a null allele. Moreover, the generation of shRNA knockdown mice and subsequent phenotypic analysis can be achieved in a condensed timeline compared to that of conventional gene-targeting knockout strategies. Here, we discuss methods for the in vivo analysis of gene function in adult mouse tissues following tetracycline-induced RNA knockdown in a single-copy inducible polymerase III promoter-driven shRNA system.
小发夹RNA(shRNA)在哺乳动物细胞中的表达可引发强大的RNA干扰(RNAi)介导的基因沉默。显性作用的RNAi通常会导致与无效等位基因相似的表型。此外,与传统的基因靶向敲除策略相比,shRNA敲低小鼠的产生及随后的表型分析可以在更短的时间内完成。在此,我们讨论了在单拷贝诱导型聚合酶III启动子驱动的shRNA系统中,通过四环素诱导的RNA敲低后,对成年小鼠组织中基因功能进行体内分析的方法。
