IGF-Binding Protein-3-Induced Growth Inhibition and Apoptosis Do Not Require Cell Surface Binding and Nuclear Translocation in Human Breast Cancer Cells
1 Jul 2002
Abstract excerpt
IGF-binding protein-3 (IGFBP-3) has both antiproliferative and proapoptotic effects on the growth of human breast cancer cells in vitro. However, the mechanisms governing these effects are not well understood. IGFBP-3 has been shown to associate with the cell surface through carboxyl-terminal residues. This suggests that it may interact with a specific cell surface receptor, although a signaling receptor for...
