Abstract excerpt
In cell culture systems insulin-like growth factor (IGF)-binding protein-3 (IGFBP-3) can both enhance and inhibit IGF-I action. To investigate the biological role of IGFBP-3 in vivo, transgenic (Tg) mice that constitutively overexpress the human IGFBP-3 complementary DNA (cDNA) driven by the mouse phosphoglycerate kinase I (PGK) and the cytomegalovirus (CMV) promoters were examined. Serum levels of human IGFBP-3...
