短发夹RNA(shRNA)筛选是在功能丧失研究中探测遗传依赖性的有力工具,例如在癌症研究中识别治疗靶点。嵌入内源性microRNA环境中的慢病毒递送的shRNA(shRNAmiR)介导靶基因的有效长期抑制,适用于许多实验环境和临床应用。在这里,描述了一个易于使用的实验室方案,包括设计和集中的shRNAmiR文库合并组装成优化的Tet-inducible all-in-one慢病毒载体,包装病毒颗粒,然后在细胞DNA回收后检索和定量发夹序列。从基因列表开始到识别命中,该方案能够在6周内进行shRNA筛选。
Short hairpin RNA (shRNA) screens are powerful tools to probe genetic dependencies in loss-of-function studies, such as the identification of therapeutic targets in cancer research. Lentivirally delivered shRNAs embedded in endogenous microRNA contexts (shRNAmiRs) mediate efficient long-term suppression of target genes suitable for numerous experimental contexts and clinical applications. Here, an easy-to-use laboratory protocol is described, covering the design and pooled assembly of focused shRNAmiR libraries into an optimized, Tet-inducible all-in-one lentiviral vector, packaging of viral particles, followed by retrieval and quantification of hairpin sequences after cellular DNA-recovery. Starting from a gene list to the identification of hits, the protocol enables shRNA screens within 6 weeks.
