2. Insulin-like growth factor 1 - Wikipedia

   en.wikipedia.org/wiki/Insulin-like_growth_factor_1

   The polypeptide hormone IGF-1 is synthesized primarily in the liver upon stimulation by growth hormone (GH). It is a key mediator of anabolic activities in numerous tissues and cells, such as growth hormone-stimulated growth, metabolism and protein translation. [17]

3. Insulin-like growth factor - Wikipedia

   en.wikipedia.org/wiki/Insulin-like_growth_factor

   The IGF "axis" is also commonly referred to as the Growth Hormone/IGF-1 Axis. 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 ...

4. Growth hormone - Wikipedia

   en.wikipedia.org/wiki/Growth_hormone

   IGF-1 has growth-stimulating effects on a wide variety of tissues. Additional IGF-1 is generated within target tissues, making it what appears to be both an endocrine and an autocrine/paracrine hormone. IGF-1 also has stimulatory effects on osteoblast and chondrocyte activity to promote bone growth.

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. Hypothalamic–pituitary–somatotropic axis - Wikipedia

   en.wikipedia.org/wiki/Hypothalamic–pituitary...

   The hypothalamic–pituitary–somatotropic axis (HPS axis), or hypothalamic–pituitary–somatic axis, also known as the hypothalamic–pituitary–growth axis, is a hypothalamic–pituitary axis which includes the secretion of growth hormone (GH; somatotropin) from the somatotropes of the pituitary gland into the circulation and the subsequent stimulation of insulin-like growth factor 1 ...

7. 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 ...
