The rapidly growing list of small RNA species generated by next-generation sequencing technologies has accelerated the development of new bioinformatics tools for their detection. Small RNAs generated from tRNAs, transfer RNA-derived fragments (tRFs), represent a novel challenge in accurately identifying and distinguishing them from random degradation products of tRNAs. Here, we describe a bioinformatics approach to detect tRFs in next-generation sequencing libraries. We also present a biochemical purification protocol for enriching 5' tRFs and separating them from miRNAs. And finally, we suggest reliable methods for detecting and quantifying tRFs.
下一代测序技术产生的小RNA种类迅速增加,加速了用于检测它们的新生物信息学工具的开发。从tRNA产生的小RNA,即转移RNA衍生片段(tRF),在准确识别它们并将其与tRNA的随机降解产物区分开来方面提出了新的挑战。在这里,我们描述了一种在下一代测序文库中检测tRF的生物信息学方法。我们还提出了一种生化纯化方案,用于富集5' tRF并将它们与miRNA分离。最后,我们提出了检测和定量tRF的可靠方法。
