Insulin-Like Growth Factor Binding Protein-3 (IGFBP-3): …
2020年5月5日 · Insulin-like growth factor (IGF) binding protein-3 (IGFBP-3), one of the six members of the IGFBP family, is a key protein in the IGF pathway. IGFBP-3 can function in an IGF-dependent as well as in an IGF-independent manner.
Mayo Clinic Laboratories | Endocrinology Catalog
Insulin-like growth factor-binding protein 3 (IGFBP-3) is a 264-amino acid peptide (molecular weight 29 kDa) produced by the liver. It is the most abundant of a group of IGFBPs that transport and control bioavailability and half-life of the insulin-like growth factors (IGF), in particular IGF-1, the major mediator of the anabolic- and growth ...
IGFBP-1 in cancer: expression, molecular mechanisms, and …
In this review, we provided an overview of IGFBP-1 in normal physiology, and its aberrantly expression and the underlying molecular mechanisms in a range of common tumors, as well as discussed the potential clinical implications of IGFBP-1 …
IGF-Binding Proteins: Why Do They Exist and Why Are There So …
2018年4月8日 · In the bloodstream and in local tissues, most IGF molecules are bound by one of the members of the IGF-binding protein (IGFBP) family, of which six distinct types exist. These proteins bind to IGF with an equal or greater affinity than the IGF1 receptor and are thus in a key position to regulate IGF signaling globally and locally.
Insulin-like growth factors: Ligands, binding proteins, and …
The insulin-like growth factor family of ligands (IGF-I, IGF-II, and insulin), receptors (IGF-IR, M6P/IGF-IIR, and insulin receptor [IR]), and IGF-binding proteins (IGFBP-1-6) play critical roles in normal human physiology and disease states. ...
Regulation of IGFBP-1 in Metabolic Diseases - PMC
IGFBP-1 secretion is regulated by a variety of pathological and physiological signals . Serum level of IGFBP-1 is associated with metabolic nutritional factors and increases IGF-1 concentration, resulting in reciprocal regulation of plasma insulin level. Glucagon acts as an activator of serum IGFBP-1 independently of insulin level . This ...
IGF binding proteins in cancer: mechanistic and clinical insights
2014年4月10日 · The insulin-like growth factor (IGF) binding proteins (IGFBPs) are a family of six proteins that function as transport proteins for IGF-I and IGF-II in the circulation and also...
IGFB3 - Overview: Insulin-Like Growth Factor-Binding Protein 3, …
For all applications, insulin-like growth factor 1 (IGF-1) measurement has generally been shown to have superior diagnostic sensitivity and specificity compared with insulin-like growth factor-binding protein 3 (IGFBP-3). IGFBP-3 testing should, therefore, usually be combined with IGF-1 testing.
The insulin-like growth factor-binding protein (IGFBP) superfamily
Over the last decade, the concept of an IGFBP family has been well accepted, based on structural similarities and on functional abilities to bind IGFs with high affinities. The existence of other potential IGFBPs was left open.
Insulin-Like Growth Factor Binding Protein-5 in Physiology and …
2020年3月3日 · Insulin-like growth factor (IGF) signaling is regulated by a conserved family of IGF binding proteins (IGFBPs) in vertebrates. Among the six distinct types of IGFBPs, IGFBP-5 is the most highly conserved across species and has the broadest range of biological activities.
