This disclosure provides data showing that LEFTY inhibits differentiation-promoting pathways such as BMP7/pSMAD5 in breast cancer cell lines, over and above its known role of inhibiting Nodal/pSMAD2. LEFTY competes with BMP7 to bind to its cell surface receptor BMPR2, leading to inhibition of pSMAD5...
