[Abstract]  Although temporal regulation of gene expression during the course of infection is known to be critical for determining the outcome of host-virus interactions, systematic temporal analysis of the miRNA targetomes during productive viral infection has been technically challenging due to the large range of miRNA-mRNA cross-talks at the host-virus interface. High-confidence quantifying models of the suppression efficacy in targeting sites by integrating bioinformatics with Argonaute-crosslinking and immunoprecipitation followed by high-throughput sequencing (AGO-CLIP-seq) (Chi et al., 2009) data have been poorly developed. To accurately identify miRNA target sites and calculate the targeting efficacy of miRNA-target interactions, we developed a new bioinformatic quantitation method, ... [摘要]  尽管已知在感染过程中基因表达的时间调节对于确定宿主 - 病毒相互作用的结果是至关重要的,但是在生产性病毒感染期间对miRNA targetomes的系统时间分析在技术上是具有挑战性的,因为大范围的miRNA- mRNA在主机 - 病毒接口交叉对话。数据通过将生物信息学与Argonaute-交联和免疫沉淀接着高通量测序(AGO-CLIP-seq)数据(Chi等人,2009)数据结合,已经不发达。为了准确地鉴定miRNA靶位点并计算miRNA-靶相互作用的靶向效果,我们开发了新的生物信息学定量方法,即AGO-CLIP-seq富集(ACE) - 评分算法(Kim等, 2015)。在我们的AGO-CLIP-seq分析中包括未感染的对照可以显着提高病毒或人miRNA的真实靶位点识别的准确性,并且在我们的ACE评分方法中提取生产性人巨细胞病毒(HCMV)感染期间的生理学显着变化。因此,我们建议我们新的基于ACE评分的方法可以应用于各种miRNA targetome研究,这将在其他类型的时间背景下进行,如发展阶段,细胞因子或病原体的免疫刺激和其他病毒。

[Abstract]  The fate of mRNA, in particular its stability, localization and rate of translation is regulated by RNA binding proteins assembling to messenger ribonucleoprotein (mRNP) complexes. To investigate the transcriptome-wide RNA binding sites of UPF1, the core factor of nonsense-mediated mRNA decay (NMD), we performed individual-nucleotide-resolution UV cross-linking and immunoprecipitation (iCLIP) (Zund et al., 2013) followed by high-throughput sequencing. The presented protocol is optimized to investigate the RNA-binding sites of UPF1 and is based on previously described studies (Konig et al., 2010; Konig et al., 2011; Hafner et al., 2010). We want to thank the Group of Mihaela Zavolan (Swiss Institute of Bioinformatics, Basel, Switzerland) and Jernej Ule ... [摘要]  mRNA的命运,特别是其稳定性,定位和翻译速率由装配到信使核糖核蛋白(mRNP)复合物的RNA结合蛋白调节。 为了研究无义介导的mRNA衰变(NMD)的核心因子UPF1的转录组范围的RNA结合位点,我们进行单个核苷酸分辨率的UV交联和免疫沉淀(iCLIP)(Zund等,/em>,2013),然后进行高通量测序。 优化所提出的方案以研究UPF1的RNA结合位点并且基于先前描述的研究(Konig等人,2010; Konig等人,2011; Hafner等人,2010)。 我们要感谢Mihaela Zavolan(瑞士巴塞尔瑞士生物信息学研究所)和Jernej Ule(英国剑桥的分子生物学医学研究委员会实验室)组织这些实验的技术支持。
