Sample Preparation and Differential Gene Expression Analysis of Human Cancer Cell Lines by RNA Sequencing.

ABSTRACT

RNA sequencing (RNA-seq) is a method used for the high-throughput quantification of mRNA in a biological sample. It is widely used to investigate differential gene expression between drug-resistant and sensitive cancers to identify genetic mediators of drug resistance. Here, we describe a comprehensive experimental and bioinformatic pipeline to isolate mRNA from human cell lines, prepare mRNA libraries for next-generation sequencing, and perform post-sequencing bioinformatics analyses.
