Serum IGF-I is controlled by several different regulatory factors. The final adult level represents the sum of the inert circulating depot, newly derived IGF-I synthesized from various tissues including liver, heart, kidney, bone, and others, and the departure from the circulation of IGF-I through mechanisms including receptor internalization and ...

IGF‐I and the IGF‐I receptor in development of nonmammalian vertebrates
Molecular Reproduction and Development, 1993AbstractExtracellular signals are likely to be involved in the control of growth and differentiation during embyrogenesis of vertebrates. These signals include, among others, several members of the insulin family: insulin‐like growth factor (IGF)‐I, IGF‐II, and insulin. In the chick embryo, maternal IGF‐I is stored in the yolk.

Patient Selection for IGF-I Therapy
Hormone Research, 2006• Many patients previously classified as 'idiopathic short stature' have Primary IGFD. In some studies, this number is as high as 50%. • For patients with severe Primary IGFD, treatment of choice should be IGF-I, either alone or in combination with IGFBP-3.

Abstract. Binding of 125I-insulin-like growth factor-I and 125I-ovine somatomedin-C/IGF-I to monolayer cultures of muscle-derived ovine fibroblasts is described. Preliminary competitive binding experiments indicate that ovine fibroblasts possess independent cell surface receptors for IGF-I.

Growth hormone (GH) and insulin-like growth factor-I (IGF-I) are relevant regulators of bone homeostasis throughout human life, acting on both the trabecular and cortical bone [1]. The anabolic effects of these hormones are important to reach an adequate bone mass during puberty and early adulthood—a critical determinant for the future risk of ...

AbstractConstitutive overexpression of the insulin‐like growth factor‐I (IGF‐I) receptor makes 3T3 cells capable of growing in serum‐free medium supplemented solely with IGF‐I to the total exclusion of the platelet‐derived growth factor (PDGF) and epidermal growth factor (EGF) receptors, the other two receptors that are required for the growth of 3T3 ...

Utility of Free IGF-I Measurements
Pituitary, 2007For nearly 30 years, the endogenous bioactivity of insulin-like growth factor I (IGF-I) has been estimated by its circulating concentrations of immunoreactive IGF-I, obtained after either removal or inactivation of the IGF-binding proteins (IGFBPs), and today serum/plasma total IGF-I serves as a useful parameter in the diagnosis and clinical control of

As the significance of putative intraovarian regulators becomes increasingly recognized, much of the attention centers on insulin-like growth factors (IGFs). Indeed, a large body of evidence now suggests the existence of an intraovarian IGF system complete with ligands, receptors, and binding proteins.

Clinical proteomics: Insights from IGF-I
Clinica Chimica Acta, 2018Clinical proteomics aims to deliver cost-effective multiplexing of potentially hundreds of diagnostic proteins, including distinct protein isoforms. The analytical strategy known as targeted proteomics is particularly promising because it is compatible with robust mass spectrometry (MS)-platforms already implemented in many clinical laboratories for ...

IGF I Receptor Phosphorylation
1989Physiologically, cells are simultaneously exposed to a plethora of hormones. The way in which a cell responds to stimulation by a specific hormone depends not only upon the concentration of that hormone, but upon the presence of other hormones as well.
