ESRP1 and cancer: In the context of cancer-related cellular programs, the best example illustrating this concept was provided by a recent study of Warzecha and collaborators, who uncovered a network of alternative splicing changes that are under the control of the ESRP1 (RBM35A) and ESRP2 (RBM35B) splicing factors and that contribute to the epithelial-mesenchymal transition (EMT) [54].
