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 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 ...

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

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

   Approximately 98% of IGF-1 is always bound to one of six binding proteins (IGF-BP). 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.

6. Neurobiological effects of physical exercise - Wikipedia

   en.wikipedia.org/wiki/Neurobiological_effects_of...

   Neuroplasticity is the process by which neurons adapt to a disturbance over time, and most often occurs in response to repeated exposure to stimuli. [27] Aerobic exercise increases the production of neurotrophic factors [note 1] (e.g., BDNF, IGF-1, VEGF) which mediate improvements in cognitive functions and various forms of memory by promoting blood vessel formation in the brain, adult ...

7. Growth hormone - Wikipedia

   en.wikipedia.org/wiki/Growth_hormone

   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 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 ...
