Circulating IGF-I, IGFBP-3 and the IGF-I/IGFBP-3 Molar Ratio
High levels of IGFBP-3 within tumors are associated with increased cancer severity (or worse outcome) for some cancers, but decreased severity or better outcome for others. No cases of IGFBP3 gene deletion in humans have been reported, but mice lacking the gene show near-normal growth. Ver mais Insulin-like growth factor-binding protein 3, also known as IGFBP-3, is a protein that in humans is encoded by the IGFBP3 gene. IGFBP-3 is one of six IGF binding proteins (IGFBP-1 to IGFBP-6) that have highly conserved … Ver mais IGFBP-3 was first isolated, characterized, and quantitated in human plasma, in 1986. It has well-documented functions in the circulation, in the … Ver mais IGFBP-3 mRNA is expressed in all tissue examined, with kidney, stomach, placenta, uterus and liver showing highest expression in rat tissues. Rat liver IGFBP-3 mRNA is found in … Ver mais IGFBP-3 exerts antiproliferative effects in many cell types by blocking the ability of IGF-1 and IGF-2 to activate the IGF1R (which stimulates cell proliferation). For example, in esophageal epithelial cells, responsiveness to IGF-1 stimulation is suppressed by … Ver mais The IGFBP3 gene (or IBP3), on human chromosome 7, is organized into four protein-coding exons with a 5th exon in the 3’ untranslated … Ver mais The main IGFBP-3 ligands in the circulation are IGF-1 and IGF-2, and the acid-labile subunit (ALS). The serum proteins Ver mais Based on cell growth experiments, animal cancer models, and epidemiological studies, it appears that IGFBP-3 functions as a low-penetrance tumor suppressor gene.
