The Insulin-Like Growth Factor System
The insulin-like growth factor (IGF) system in ubiquitous and plays a role in every tissue of the body. It is comprised of ligands, receptors and binding proteins, each with specific functions. While it plays an essential role in embryonic and post-natal development, the IGF system is also important in normal adult physiology. There are now numerous examples of diseases such as diabetes, cancer...
متن کاملInsulin-like Growth Factor System and Aging
IGF (insulin-like growth factor, IGF) system is composed of three ligands (insulin, IGF-1, IGF-2), three cell surface binding receptors (Ins R, IGF-1R, IGF-2 R), and Insulin-like growth factor binding proteins (IGF binding proteins, IGFBPs) and IGFBP protease. Delaying aging and exploring the molecular mechanism of aging have always been important research topics. IGF system plays an important ...
متن کاملThe Insulin-Like Growth Factor System in the Human Pathology
Insulin-like growth factors are single chain polypeptides. There are two principle IGFs referred to as IGF-I and IGF-II. IGF-1 is a polypeptide hormone with a molecular weight of 7.6-kDa structurally similar to insulin. In 1957, it is identified by Salmon and Daughaday. Because of the its ability to stimulate the sulfation of the cartilage proteoglycans, it was regarded as a sulphation factor [...
متن کاملDoxorubicin Impairs the Insulin-Like Growth Factor-1 System and Causes Insulin-Like Growth Factor-1 Resistance in Cardiomyocytes
BACKGROUND Insulin-like growth factor-1 (IGF-1) promotes the survival of cardiomyocytes by activating type 1 IGF receptor (IGF-1R). Within the myocardium, IGF-1 action is modulated by IGF binding protein-3 (IGFBP-3), which sequesters IGF-1 away from IGF-1R. Since cardiomyocyte apoptosis is implicated in anthracycline cardiotoxicity, we investigated the effects of the anthracycline, doxorubicin,...
متن کاملModeling the Insulin-Like Growth Factor System in Articular Cartilage
IGF signaling is involved in cell proliferation, differentiation and apoptosis in a wide range of tissues, both normal and diseased, and so IGF-IR has been the focus of intense interest as a promising drug target. In this computational study on cartilage, we focus on two questions: (i) what are the key factors influencing IGF-IR complex formation, and (ii) how might cells regulate IGF-IR comple...
