In pancreatic ductal adenocarcinoma, TGF-β/Activin induce epithelial-to-mesenchymal transition (EMT) and stemness. Here, the authors show that TGF-β induces pro-tumourigenic miR-100 and miR-125b, but blocks anti-tumourigenic let-7a maturation via LIN28B, regulating pathways to promote stemness, EMT and tumourigenesis.
