[Abstract]  microRNA (miRNA) directly associates with its target transcripts (mRNA). This protocol describes a method for detection of direct interaction between miRNA and mRNA. The result of interaction helps screening the specific target mRNAs for a miRNA. [摘要]  microRNA(miRNA)与其目标转录物(mRNA)直接相关。 该方案描述了检测miRNA和mRNA之间直接相互作用的方法。 相互作用的结果有助于筛选miRNA的特异性靶mRNA。

背景 MiRNA是小的非编码调控RNA。 MiRNA通常通过与靶mRNA中的互补序列结合来控制基因表达。 许多生物信息学和计算程序可用于预测miRNA靶标。 但是鉴定miRNA与靶mRNA的直接相关性的实验方法非常有限。 目前的方案可以非常有助于识别miRNA靶标(Phatak等人,2016)。

[Abstract]  Adeno-associated virus (AAV)-based targeting vectors have 1-4-log higher gene targeting efficiencies compared with plasmid-based targeting vectors. The efficiency of AAV-mediated gene targeting is further increased by introducing a promoter-trap system into targeting vectors. In addition, we found that the use of ribosome-skipping 2A peptide rather than commonly used internal ribosome entry site (IRES) in the promoter-trap system results in significantly higher AAV-mediated gene targeting efficiencies (Karnan et al., 2016). In this protocol, we describe the procedures for AAV-mediated gene targeting exploiting 2A for promoter trapping, including the construction of a targeting vector based on the platform plasmid pAAV-2Aneo or pAAV-2Aneo v2, production of AAV particles, infection ... [摘要]  与基于质粒的靶向载体相比,基于腺相关病毒(AAV)的靶向载体具有1-4对较高的基因靶向效率。 通过将启动子捕获系统引入靶向载体中,AAV介导的基因靶向的效率进一步增加。 此外,我们发现使用核糖体跳跃2A肽而不是通常使用的内部核糖体进入位点(IRES)在启动子捕获系统中导致显着更高的AAV介导的基因靶向效率(Karnan等,2016)。 在该方案中,我们描述了AAV介导的基因靶向开发2A用于启动子捕获的程序,包括基于平台质粒pAAV-2Aneo或pAAV-2Aneo v2的靶向载体的构建,AAV颗粒的产生,细胞感染 基于AAV的靶向载体,以及基因靶向细胞克隆的分离和验证。
【背景】以前在其他方案中描述了AAV介导的基因靶向的程序(对应于本方案的BG部分)(Kohli等人,2004; Rago等人,2007; Khan等人,2011; Howes and Schofield ,2015)。 然而,该方案提供了如何使用基于2A的启动子捕获系统首次进行AAV介导的基因靶向的详细描述。
