Somatostatin is a hormone produced by many tissues in the body, principally in the nervous and digestive systems.

Growth hormone—releasing hormone GHRH , also known as somatocrinin or by several other names in its endogenous forms and as somatorelin INN in its pharmaceutical form , is a releasing hormone of growth hormone GH. It is a 44 [1] - amino acid peptide hormone produced in the arcuate nucleus of the hypothalamus. GHRH first appears in the human hypothalamus between 18 and 29 weeks of gestation, which corresponds to the start of production of growth hormone and other somatotropes in fetuses. GHRH is released from neurosecretory nerve terminals of these arcuate neurons, and is carried by the hypothalamo- hypophyseal portal system to the anterior pituitary gland , where it stimulates growth hormone GH secretion by stimulating the growth hormone-releasing hormone receptor. In addition, GHRH also promotes slow-wave sleep directly. The GHRHR is a member of the secretin family of G protein-coupled receptors , and is located on chromosome 7 in humans.

Authors Timothy J. O'Toole 1 ; Sandeep Sharma 2. Somatostatin is a cyclic peptide well known for its strong regulatory effects throughout the body. Also known by the name of growth hormone inhibiting hormone, it is produced in many locations, which include the gastrointestinal GI tract, pancreas, hypothalamus, and central nervous system CNS. Two active forms of the peptide exist, and they vary in length at fourteen amino acids and twenty-eight amino acids respectively. The two isoforms have considerable overlap in activity and differ primarily in their location of effect. The shorter isoform 14 amino acids works primarily in the brain, while the longer 28 amino acids form operates in the GI tract. Its half-life is between 1 to 3 minutes. Somatostatin produces predominantly neuroendocrine inhibitory effects across multiple systems.

Somatostatin , also known as growth hormone-inhibiting hormone GHIH or by several other names , is a peptide hormone that regulates the endocrine system and affects neurotransmission and cell proliferation via interaction with G protein-coupled somatostatin receptors and inhibition of the release of numerous secondary hormones. Somatostatin inhibits insulin and glucagon secretion. Somatostatin has two active forms produced by the alternative cleavage of a single preproprotein: one consisting of 14 amino acids shown in infobox to right , the other consisting of 28 amino acids. Synonyms of "somatostatin" include: [ citation needed ]. Somatostatin is secreted by delta cells at several locations in the digestive system, namely the pyloric antrum , the duodenum and the pancreatic islets. Somatostatin released in the pyloric antrum travels via the portal venous system to the heart, then enters the systemic circulation to reach the locations where it will exert its inhibitory effects.

Somatostatin released in the pyloric antrum travels via the portal venous system to the heart, then enters the systemic circulation to reach the locations where it will exert its inhibitory effects. In addition, somatostatin release from delta cells can act in a paracrine manner. In the stomach, somatostatin acts directly on the acid-producing parietal cells via a G-protein coupled receptor which inhibits adenylate cyclase, thus effectively antagonising the stimulatory effect of histamine to reduce acid secretion. Somatostatin is produced by neuroendocrine neurons of the ventromedial nucleus of the hypothalamus.

Development As previously mentioned, the two types of somatostatin differ in length of amino acids. Normal Physiology of Growth Hormone in Adults. The inhibitory effect of somatostatin leads to decreased gallbladder emptying as well as reduced cholecystokinin production, which results in gallstones. It also prevents angiogenesis and has anti-proliferative effects on healthy and cancerous cells in human and animal models. You and Your Hormones.

While there is no data relating to under-production of somatostatin, there are documented cases of over-production of somatostatin referred to as somatostatinoma.
