Summary	Insulin-like growth factor-binding protein 3 (IGFBP3) is a member of IGF binding protein superfamily. IGF binding proteins prolong the half-life of the IGFs and have been shown to either inhibit or stimulate the growth-promoting effects of the IGFs on cell culture. IGFBP3 is expressed by most tissues and the expression levels are higher during development. It is up-regulated in the presence of IGF1, insulin and other growth-stimulating factors such as growth hormone, EGF and phorbol esters. IGFBP3 is the most abundant IGF binding protein in human serum and has been shown to be a growth inhibitory, apoptosis-inducing molecule, capable of acting via IGF-dependent and IGF-independent mechanisms. Several clinical studies have shown that individuals with IGFBP3 levels in the upper range of normal may have a decreased risk for certain common cancers
