Estrogen Signaling via a Linear Pathway Involving Insulin-Like Growth Factor I Receptor, Matrix Metalloproteinases, and Epidermal Growth Factor Receptor to Activate Mitogen-Activated Protein Kinase in MCF-7 Breast Cancer Cells
Abstract
We present an integrated model of an extranuclear, estrogen receptor-α (ERα)-mediated, rapid MAPK activation pathway in breast cancer cells. In noncancer cells, IGF-I initiates a linear process involving activation of the IGF-I receptor (IGF-IR) and matrix metalloproteinases (MMP), release of heparin-binding epidermal growth factor (HB-EGF), and activation of EGF receptor (EGFR)-dependent MAPK. 17β-Estradiol (E2) rapidly activates IGF-IR in...
