Besides ESRP1 and ESRP2 that were selected on the basis of their documented effect on ITGA6 splicing in breast and renal neoplastic cells [25,26], respectively, we also tested the three MYC-controlled factors of the heterogeneous nuclear RNA-binding protein (hnRNP) family in cancer cells: PTBP1, hnRNPA1 and hnRNPH1 [38,39]. Here, PTBP1 is linked to cancer.
