2. Insulin-like growth factor 1 - Wikipedia

   en.wikipedia.org/wiki/Insulin-like_growth_factor_1

   Low IGF-1 levels are shown to increase the risk of developing type 2 diabetes and insulin resistance. [67] On the other hand, a high IGF-1 bioavailability in people with diabetes may delay or prevent diabetes-associated complications, as it improves impaired small blood vessel function. [67] IGF-1 has been characterized as an insulin sensitizer ...

3. Insulin-like growth factor - Wikipedia

   en.wikipedia.org/wiki/Insulin-like_growth_factor

   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 ...

4. Insulin-like growth factor-binding protein - Wikipedia

   en.wikipedia.org/wiki/Insulin-like_growth_factor...

   IGF-1 binds to IGFBP-3 in a 1:1 molar ratio. IGF-BP also binds to IGF-1 inside the liver, allowing growth hormone to continuously act upon the liver to produce more IGF-1. IGF binding proteins (IGFBPs) are proteins of 24 to 45 kDa. All six IGFBPs share 50% homology with each other and have binding affinities for IGF-I and IGF-II at the same ...

5. Insulin-like growth factor 1 receptor - Wikipedia

   en.wikipedia.org/wiki/Insulin-like_growth_factor...

   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 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-1 ...

6. Insulin-like growth factor 2 - Wikipedia

   en.wikipedia.org/wiki/Insulin-like_growth_factor_2

   IGF-2 exerts its effects by binding to the IGF-1 receptor and to the short isoform of the insulin receptor (IR-A or exon 11-). [9] IGF-2 may also bind to the IGF-2 receptor (also called the cation-independent mannose 6-phosphate receptor), which acts as a signalling antagonist; that is, to prevent IGF-2 responses.

7. Growth hormone - Wikipedia

   en.wikipedia.org/wiki/Growth_hormone

   GH also stimulates, through the JAK-STAT signaling pathway, [39] the production of insulin-like growth factor 1 (IGF-1, formerly known as somatomedin C), a hormone homologous to proinsulin. [40] The liver is a major target organ of GH for this process and is the principal site of IGF-1 production. IGF-1 has growth-stimulating effects on a wide ...

8. Isolated growth hormone deficiency - Wikipedia

   en.wikipedia.org/wiki/Isolated_growth_hormone...

   The diagnosis of growth hormone deficiency is a multi-step procedure that involves pituitary MRI, biochemical testing (growth hormone stimulation tests and measurement of IGF-1/IGFBP3), clinical and auxological examination, and genetic test results. [8]

9. Bone growth factor - Wikipedia

   en.wikipedia.org/wiki/Bone_growth_factor

   A bone growth factor is a growth factor that stimulates the growth of bone tissue. [1] [2]Known bone growth factors include insulin-like growth factor-1 (IGF-1), insulin-like growth factor-2 (IGF-2), transforming growth factor beta (TGF-β), fibroblast growth factors (FGFs), platelet-derived growth factor (PDGF), parathyroid hormone-related peptide (PTHrP), bone morphogenetic proteins (BMPs ...
