TF and breast carcinoma: Breast cancer cells MCF748 and epithelial subclones from immortalized humanmammary epithelial cells HMLE49—that had low EMT scores47—expressed high levels of ESRP1 and lowlevels of ZEB1, whereas MCF7 cells transfected with EMT-TF SNAIL and mesenchymalsubclones from HMLE exhibited a reverse trend [Fig. 3(a), i–ii; GSE58252 and GSE28681] and had higher EMTscores.
