We transduced p18-/-;Brca1MGKO tumor cells with pBabe-Empty and pBabe-Gata3 respectively, and found that ectopic Gata3 restored expression of Cdh1, a target of Gata3, but inhibited expression of Vim and EMT-TFs including Slug, Snail, and Twist1 (Figure 6A, B), which was stimulated by loss of Brca1 in mammary tumors (Figure 1A, Figure S1). This evidence concerns the gene SNAI2 and breast cancer.
