2. Insulin-like growth factor - Wikipedia

   en.wikipedia.org/wiki/Insulin-like_growth_factor

   Insulin-like growth factor 1 (commonly referred to as IGF-1 or at times using Roman numerals as IGF-I) is mainly secreted by the liver as a result of stimulation by growth hormone (GH). IGF-1 is important for both the regulation of normal physiology, as well as a number of pathological states, including cancer.

   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 ...

   en.wikipedia.org/wiki/Laron_syndrome

   Laron syndrome (LS), also known as growth hormone insensitivity or growth hormone receptor deficiency (GHRD), is an autosomal recessive disorder characterized by a lack of insulin-like growth factor 1 (IGF-1; somatomedin-C) production in response to growth hormone (GH; hGH; somatotropin). [6] It is usually caused by inherited growth hormone ...

   Insulin-like growth factor II E-peptide (somatomedians-A ) Insulin-like growth factor 2 (IGF-2) is one of three protein hormones that share structural similarity to insulin. The MeSH definition reads: "A well-characterized neutral peptide believed to be secreted by the liver and to circulate in the blood.

6. Insulin signal transduction pathway - Wikipedia

   en.wikipedia.org/wiki/Insulin_signal...

   Several hormones can affect insulin secretion. Estrogen is correlated with an increase of insulin secretion by depolarizing the β-cells membrane and enhancing the entry of Ca+2. In contrast, growth hormone is known to lower the serum level of insulin by promoting the production of insulin-like growth factor-I (IGF-I).

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

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

   IGFBP-3, the most abundant protein, accounts for 80% of all IGF binding. 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 ...
