Growth Factors - IGF1   (Site not responding. Last check: 2007-10-24) IGF1 is primarily secreted by the liver in response to a signal from human growth hormone (hGH). IGF1 communicates an anabolic signal to cells, regulating cell division and differentiation as the muscle acquires an increased need for strength or as injury to the muscle is incurred. IGF1 acts within the nervous system and is critical for the growth and development of nerve cells. www.biomedcomm.com /store/hgh_gf_igf1.html   (554 words)

Insulin-like Growth Factor-1 IGF1 belongs in the ‘superfamily’ of substances known as ‘growth factors,’ along with epidermal, transforming, platelet derived, fibroblast, nerve, and ciliary neurotrophic growth factors. Because IGF1 is mitogenic to prostate epithelial cells, as well as other cell lines in tissue culture, its role, if any, in prostate cancer has been considered and raises the question as to whether higher levels of circulating IGF1 might increase the risk of prostate cancer. IGF1 levels were further broken down into quartiles and compared with PSA levels in each. drcranton.com /hrt/insulinlike_growth_factor1.htm   (731 words)

ProTrainerOnline.com IGF1 levels increase in muscle tissues during resistance exercise partly by virtue of increased muscle cellular synthesis of IGF1 and partly due to increased serum levels of growth hormones (GH), which promotes synthesis of IGF1. So close is the similarity between insulin and IGF1, that both generate their anabolic actions through the same growth signaling compound P 1 3K (Phosphatidylinositol –3-kinase). IGF1, however, has a more profound anabolic effect, whereas insulin is believed to facilitate mostly an anti-catabolic effect. www.protraineronline.com /April05/article4.cfm   (1761 words)

IGF1 - Insulin Growth Factor! IGF1 Works!   (Site not responding. Last check: 2007-10-24) IGF1 is produced after growth hormone is secreted by the pituitary gland and then taken into the liver. IGF1 has also been shown to repair nerve damage, which not only occurs from accidents, but also from poor nutrition, stress, disease and pollution. IGF1 and HGH work together in a synergistic manner enhancing each others abilities, and although they both do many of the same things, there are also functions each of them performs that the other does not.* www.ultranutraceuticals.com /igf1.htm   (512 words)

IGF1 and Brain Development   (Site not responding. Last check: 2007-10-24) During the course of brain development, insulin-like growth factor (IGF1) and the IGF1 receptor are most highly expressed by maturing projection neurons during a time of rapid process growth and synaptogenesis. IGF1 deletion results in reduced neuronal size, dendrite growth, branching and synapse formation and a selective decrease in dentate gyrus and olfactory neuron survival. Taken together with the fact that IGF1 and IGF1 receptor expression are predominantly neuronal, these findings suggest that IGF1’s effects on developmental myelination are secondary to its direct effects on neuronal growth and survival. www.eurekah.com /abstract.php?chapid=982&bookid=34&catid=19   (413 words)

BeyondMass - The IGF story,..The what, the hows, & the whys! IGF1 belongs in the 'superfamily' of substances known as 'growth factors,' along with epidermal (skin), transforming; platelet derived fibroblast, nerve, and ciliary neurotrophic growth factors. Users of IGF1 have reported various results but all along the same lines, It does not appear to be dramatically less effective in any one individual (at least not to the best of my knowledge). I have a good friend who had to stop taking IGF1 due to stomach illness that was completely unrelated But he to experienced good gains from it for the 2 weeks he was on it, his dosage was 120mcg per day. www.beyondmass.com /forums/showthread.php?threadid=946   (1995 words)

IGF1 assists competent cells toward cell division and often that is all cells need for successful activation and often that is all cells need for successful activation. Hormonal functions such as the anabolic (constructive) activity of HGH depends on the production and presence of IGF1 to achieve positive results. www.kchgh.com /hgh_famous_igf1.htm   (622 words)

Variation In IGF1 Gene Associated With Risk Of Prostate Cancer A new study suggests that genetic variation in the insulin-like growth factor 1 (IGF1) gene may be associated with the risk of prostate cancer. Matthew Freedman, M.D., at the Dana-Farber Cancer Institute and Broad Institute of Harvard and MIT in Cambridge, and colleagues examined specific variations in the IGF1 gene called single nucleotide polymorphisms (SNPs) largely derived from a public SNP database in 4610 individuals with and without prostate cancer. They identified two specific polymorphisms on the IGF1 gene that were associated with an increased risk of prostate cancer. www.medicalnewstoday.com /medicalnews.php?newsid=36360&nfid=rssfeeds   (257 words)

IGF1 Receptor (phospho Y1158) antibody (ab5679) datasheet   (Site not responding. Last check: 2007-10-24) IGF1 receptor is a disulfide-linked heterotetrameric transmembrane protein consisting of two alpha (130 kD) and two beta (95 kD) subunits. The IGF1 receptor is therefore similar in structure to the insulin receptor. The proreceptor polypeptide is proteolytically cleaved and disulfide-linked to yield the mature heterotetrameric receptor. www.abcam.com /?datasheet=5679   (764 words)

IGF1 What is interesting about this compound is that compounds such as steroids and IGF1 increase protein synthesis but this effect happens after a workout when you recover and this is where you grow.
