The Role of Heparin-Binding EGF-Like Growth Factor in Breast Cancer
Abstract
Heparin-binding epidermal growth factor-like growth factor (HB-EGF) is a member of the EGF family which binds to and activates the EGF receptor. Its role in breast cancer, however, is unclear. We have studied the regulation of HB-EGF expression in nontransformed and transformed mammary epithelial cells. HB-EGF is induced by 12-0- tetradecanoylphorbol- 13-acetate (TPA) in most of the cell lines analyzed. In contrast with transforming growth factor alpha or amphiregulin, HB-EGF is not induced by estrogen or progesterone in any of the estrogen responsive, estrogen receptor positive breast cancer cell lines examined. HB-EGF RNA levels are induced by EG-related peptides in the spontaneously immortalized mammary epithelial cell line.
