Insulin-like growth factor 1 (IGF-1), also called somatomedin C, is a hormone similar in molecular structure to insulin which plays an important role in childhood growth, and has anabolic effects in adults. [5] In the 1950s IGF-1 was called " sulfation factor" because it stimulated sulfation of cartilage in vitro, [6] and in the 1970s due to ...
The insulin-like growth factor 1 (IGF-1) receptor is a protein found on the surface of human cells. It is a transmembrane receptor that is activated by a hormone called insulin-like growth factor 1 (IGF-1) and by a related hormone called IGF-2. It belongs to the large class of tyrosine kinase receptors. This receptor mediates the effects of IGF ...
Growth hormone (GH) or somatotropin, also known as human growth hormone (hGH or HGH) in its human form, is a peptide hormone that stimulates growth, cell reproduction, and cell regeneration in humans and other animals. It is thus important in human development. GH also stimulates production of insulin-like growth factor 1 (IGF-1) and increases ...
The IGF-1 receptor is the "physiological" receptor. IGF-1 binds to it at significantly higher affinity than it binds the insulin receptor. Like the insulin receptor, the IGF-1 receptor is a receptor tyrosine kinase—meaning the receptor signals by causing the addition of a phosphate molecule on particular tyrosines. The IGF-2 receptor only ...
The drug has an estimated half-life of about 6 to 8 days in humans. [3] With multiple doses of CJC-1295, IGF-1 levels were found to remain elevated in humans for up to 28 days. [3] CJC-1295 has been shown to extend the half-life and bioavailability of growth-hormone-releasing hormone 1-29 and stimulate insulin-like growth factor 1 secretion.
Many of them also induce the secretion of insulin-like growth factor 1 (IGF-1), [6] as well as of other hypothalamic-pituitary hormones such as prolactin and cortisol. The main clinical application of these agents is the treatment of growth hormone deficiency. [7] They also see black market use, similarly to anabolic steroids, for bodybuilding ...
Insulin receptor substrate 1 (IRS-1) is a signaling adapter protein that in humans is encoded by the IRS1 gene. [5] It is a 180 kDa protein with amino acid sequence of 1242 residues. [ 6 ] It contains a single pleckstrin homology (PH) domain at the N-terminus and a PTB domain ca. 40 residues downstream of this, followed by a poorly conserved C ...
The drug is a synthetic androgen and anabolic steroid [6] and hence is an agonist of the androgen receptor (AR), the biological target of androgens like testosterone and dihydrotestosterone (DHT). [ 5 ] [ 2 ] [ 7 ] It has strong anabolic effects and highly androgenic effects, as well as potent progestogenic effects, and weak glucocorticoid effects.
