Ectopic expression of the ErbB-3 binding protein Ebp1 inhibits growth and induces differentiation of human breast cancer cell lines

Abstract excerpt

Ebp1, an ErbB-3 binding protein, translocates from the cytoplasm to the nucleus of human breast cancer cells after treatment with the ErbB-3 ligand, heregulin. The purpose of these studies was to examine the effects of ectopic expression of ebp1 on the biological properties of human ErbB-3-expressing breast carcinoma cell lines. Ectopic expression of ebp1 in ErbB-2, ErbB-3-expressing breast carcinoma cell lines...
