摘要
Insulin-like growth factor binding protein (IGFBP)-3, the major carrier of insulin-like growth factors (IGFs) in the circulation, was first isolated and characterised over a decade ago. More recently, IGFBP-3 has been assigned a role as a putative death-promoting factor, a function that appears, under certain circumstances, to be independent of its IGF-binding ability. This review examines the current evidence for a pro-apoptotic function for IGFBP-3 and speculates on its physiological significance.
