Determination of Differential Alternative Splicing Under Stress Conditions

Alternative splicing (AS) is an important mechanism contributing to stress-induced regulation of gene expression and proteome diversity. Massive sequencing technologies allow the identification of transcripts generated via stress-responsive AS, potentially important for adaptation to stress conditions. Several bioinformatics tools have been developed to identify differentially expressed alternative splicing events/transcripts from RNA-sequencing results. This chapter describes a detailed protocol for differential alternative splicing analysis using the rMATS tool. In addition, we provide guidelines for validation of the detected splice variants by qRT-PCR based on the obtained output files.
