The igf-1 is basically the Insulin-like growth factor in our body that is actually a form of polypeptide protein hormone, similar in structural build up to the hormone, insulin. It is igf-1 that plays a vital role in developing the body's growing power during childhood and straight through adolescence and scientists have found that igf-1 also has certain anabolic effects in adults too. The igf's are essentially categorized as insulin-like growth factors, which are synthesized by almost all tissues; this makes the igf and igf-1 important mediators of cell growth, differentiation, and transformation, all of which determine the health condition of the human body over various life stages. The igf-1 has a wide range of useful biologic effects and contains vital therapeutic potential that has recently proved to be of utmost importance in the prevention of cardiovascular issues, when used to balance tissue regeneration. The focus of many researches, igf-1 has been thoroughly investigated in the attempt to recognize its role in the development and repair of the human body with strong emphasis laid on the way the igf-1 expresses itself towards optimal body functioning, along with its other IGF-1 receptors, namely the IGF-1Rs. There are also other crucial counterparts to the igf-1, such as the IGF-1 binding proteins, known as IGFBPs that are present in blood vessels.
igf-1 is produced by the IGF-1 gene in the liver, which makes it an endocrine hormone; the igf-1 is a gene that has been successfully mapped to chromosome 12 in humans and a single chain of IGF-1 can well contain seventy amino acids along side three intra molecular disulphide bridges. As for the structural composition of the igf-1, it weighs at 7649 daltons.
The growth hormones in the human body are responsible for the production of the igf-1 and reasons such as lack of nutrition, low growth hormone receptors and failure of growth hormones or signaling pathway after GH receptors like SHP2 and STAT5b can result in stunting the outflow of igf-1. Recent studies indicate that close to 98% of the igf contains one of the 6 insulin-like growth factor binding proteins. Igf-1 also is known to induce hypertrophy of skeletal muscle and other target tissues.
The chief action of igf is mediated by binding proteins to specific IGF receptors that are present on many cell types in several human body tissues; beyond this basic effect, igf transfers the signal via intracellular event and emerges as the strongest natural activators of the AKT signaling pathway. This is the primary reason why igf is also regarded as a potent stimulator of cell growth and multiplication as well as a welcome inhibitor of programmed cell death, which helps divert the destruction possibilities in the human body, such as cardiovascular disease and skin cell damage.
Atherosclerosis is the leading cause of mortality in the West and the IGF-1 system works to bring about vital balance between the death and survival of VSMCs in atherosclerotic lesions, renewing hope for persons suffering this near-fatal condition.
