Development of an Autocrine Neuregulin Signaling Loop with Malignant Transformation of Human Breast Epithelial Cells

Abstract excerpt

Neuregulin (NRG) is a heparin-binding factor that activates members of the epidermal growth factor family of tyrosine kinase receptors including erbB2 that is overexpressed in more aggressive types of breast cancer. The exact role that NRG plays in breast cancer is complicated by the fact that NRG has been shown to have both proliferative and antiproliferative effects, depending on the breast cancer cell line...
