[Abstract] Small interfering RNAs (siRNAs) are small (typically 18-24 nucleotides) RNA molecules capable of silencing gene expression post-transcriptionally and as such, they provide a simple method by which the role of individual genes in complex cellular systems can be easily assessed. As siRNAs are easy to use experimentally, and can be designed to target any gene (including pathogens), their use is perfectly suited to and easily adapted to high-throughput genome-wide screening methodologies and a range of phenotypic assays. Here we describe the use of a large siRNA library (>8,000 genes targeted individually) to screen for and identify host factors functionally involved in the replication of a human herpesvirus (Herpes simplex virus type 1; HSV-1) (Griffiths et al., 2013; Griffiths, ...
[摘要] 小干扰RNA（siRNA）是能够沉默转录后基因表达的小（通常为18-24个核苷酸）RNA分子，因此，它们提供了一种简单的方法，通过其可以容易地评估单个基因在复杂细胞系统中的作用。 由于siRNA易于实验使用，并且可以设计为靶向任何基因（包括病原体），它们的使用完全适合于并且容易地适应于高通量全基因组筛选方法学和一系列表型测定。 这里我们描述了使用大的siRNA文库（> 8,000个基因单独靶向）来筛选和鉴定功能上涉及人疱疹病毒（1型单纯疱疹病毒; HSV-1）（Griffiths）的复制的宿主因子， et al。，2013; Griffiths，2013）。

[Abstract] Small Interfering RNA (siRNA) is a class of double-stranded RNAs of 20-25 nucleotides that play important roles in many biological processes (Hamilton and Baulcombe, 1999). siRNAs act by “neutralizing” the mRNA of the target protein, facilitating degradation of the mRNA and hence altering the biological effect of the protein (reviewed in Hannon and Rossi, 2004). siRNAs may also change the intracellular levels of regulatory RNAs. Use of siRNAs for manipulating the expression of genes of interest in biological research is commonly referred to as RNA interference or knockdown technique (Elbashir et al., 2001). Synthetic siRNAs are an emerging tool that are now widely used in these studies. A variety of algorithms are employed by different companies for the design of siRNA products, ...
[摘要] 小干扰RNA（siRNA）是一类20-25个核苷酸的双链RNA，在许多生物过程中起重要作用（Hamilton和Baulcombe，1999）。 siRNA通过"中和"靶蛋白的mRNA起作用，促进mRNA的降解，从而改变蛋白的生物效应（综述于Hannon和Rossi，2004）。 siRNA也可以改变调节RNA的细胞内水平。 在生物研究中使用siRNA操纵目的基因的表达通常被称为RNA干扰或敲除技术（Elbashir等人，2001）。 合成的siRNA是一种新兴的工具，现在广泛应用于这些研究。 不同公司采用多种算法来设计siRNA产品，其在功效，特异性和成本等方面不同。 在此使用来自Dharmacon的siGENOME SMARTpool试剂解释siRNA敲低的示例方案。
