ESRP1 and breast cancer: Available transcriptomics data in ESRP1/2 and RBM47 lung carcinoma NCI-H358-depleted cells [52] and RBM47 overexpressing breast cancer metastatic MDA-MB-231 cells [57] showed that 19 of the 25 splicing events responsible for the newly identified basal B-specific splicing signature could potentially be regulated by ESRP1/2 and/or RBM47 in breast cancer cells (Fig. 6c, d).
