a The fCLIP target transcripts were classified as strong-, median- or weak-affinity with MTA1 according to the fCLIP-seq data normalized by the RNA-seq expressional abundance in the control. The empirical cumulative distribution function of the log2 CrMTA1/control fold changes of the abundance for each set were plotted. b Hierarchical clustering heatmap of the differentially expressed genes (DEGs) between CrMTA1 and the control. c Venn diagram showing the overlap between the MTA1 binding transcripts (fCLIP genes) and DEGs. d The ChIP promoters were classified as strong-, median- or weak-affinity with MTA1. The affinity was defined using a binding affinity score, which is the sum of fold enrichment (MTA1-ChIP/Input) of peaks in the gene promoter region according to the ChIP-seq data. The empirical cumulative distribution function of the log2 CrMTA1/control fold changes of the abundance for each set were plotted. e Venn diagram showing the overlap between the MTA1 binding gene promoters (ChIP-promoters) and DEGs. f The fCLIP target transcripts were classified as strong-, median- or weak-affinity with MTA1 according to the fCLIP-seq data normalized by the RNA-seq expressional abundance in the control, and the empirical cumulative distribution function of the log2 CrMTA1/control fold changes of the AS ratio for each set were plotted. g The ChIP promoters were classified as strong-, median- or weak-affinity with MTA1, and the empirical cumulative distribution function of the log2 CrMTA1/control fold changes of the AS ratio for each set were plotted. h Bar plot showing that MTA1 deletion generated more IR events. IntronR, intron retentions; ES, exon skips; MXE, mutually exclusive exons; A5SS, alternative 5’ss; A3SS, alternative 3’ss. i Venn diagram showing that the transcripts of most of the RASGs were bound by MTA1. j RT-qPCR validation for the non-IR and IR events. Data are represented as mean ± SD (n = 3 per group). a, d, f and g One-way ANOVA with Tukey’s multiple comparisons test. h Two-tailed Fisher’s exact test. j Two-tailed Student’s t-test.
