Similar to NUMB, the EMT negative regulators GATA3 and FOXA1 had significantly lower expression in the BLBC subtypes and in ER-negative and higher histological grade breast cancer patients, whereas the EMT inducers FOXC1, FOXC2 and SNAI1 mimicked the expression profile of Notch1. This evidence concerns the gene GATA3 and breast carcinoma.
