High-throughput mRNA sequencing (RNA-seq) uses massively parallel sequencing to allow an unbiased analysis of both genome-wide transcription levels and mutation status of a tumor. In the RNA-seq method, complementary DNA (cDNA) is used to generate short sequence reads by immobilizing millions of amplified DNA fragments onto a solid surface and performing the sequence reaction. The resulting sequences are aligned to a reference genome or transcript database to create a comprehensive description of the analyzed transcriptome. This chapter describes a protocol to perform RNA-seq using the Illumina sequencing platform, presents sequencing data quality metrics and outlines a bioinformatic pipeline for sequence alignment, digital gene expression, and mutation discovery.
高通量mRNA测序(RNA-seq)使用大规模平行测序技术,对肿瘤的全基因组转录水平和突变状态进行无偏分析。在RNA-seq方法中,通过将数百万个扩增的DNA片段固定在固体表面并进行序列反应,利用互补DNA(cDNA)生成短序列读数。将得到的序列与参考基因组或转录本数据库进行比对,以全面描述所分析的转录组。本章介绍了使用Illumina测序平台进行RNA-seq的实验方案,给出了测序数据质量指标,并概述了用于序列比对、数字基因表达和突变发现的生物信息学流程。
