A Doughnut chart for RNA-seq analysis showing the differentially regulated alternative splicing events (ASEs) and their corresponding genes in ESRP1 knockdown cells compared to control cells; SE: skipped exon, RI: retained intron, MXE: mutually exclusive exons, A5SS: alternative 5' splice site, and A3SS: alternative 3' splice site). The "percent spliced in" (PSI or ψ) value was estimated. Differences in inclusion levels (∆ψ) between samples and their significance were calculated (P<0.05 and IΔψI>0.1). Circle 1: all ASEs; Circle 2: all genes corresponding to all ASEs; Circle 3: significant ASEs; Circle 4: significant genes corresponding to significantly altered ASEs; Circle 5: significant ASEs with ESRP1 motifs; Circle 6: significant genes corresponding to significantly altered ASEs with ESRP1 motifs. ESRP-binding motifs were obtained from Dittmar et al.31[] and analyzed based on the following assumption: the presence of the motif in the downstream region of an exon results in inclusion of the exon, while upstream or intraexonic location leads to exclusion of the exon.
