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 ...
As somatostatin can cause inhibition of hormone production that uses it as a mediating hormone, it has an antiproliferative effect on cell tumors, especially in neuroendocrine tumors. [2] Somatostatin analogue therapy uses longer-acting agonists than the endogenous somatostatin to extend the antiproliferative effects. [ 25 ]
The main release-inhibiting hormones or inhibiting hormones are as follows: The hypothalamus uses somatostatin to tell the pituitary to inhibit somatotropin and to tell the gastrointestinal tract to inhibit various gastrointestinal hormones. There are various other inhibiting factors that also have tropic endocrine inhibition activity.
The somatostatin family is a protein family with somatostatin as titular member, a hormone which inhibits the release of the pituitary somatotropin (growth hormone) and inhibits the release of glucagon and insulin from the pancreas of fasted animals. Cortistatin is a cortical neuropeptide with neuronal depressant and sleep-modulating properties ...
Cyclosomatostatin is one such compound. Contrary to previously discussed compounds, cyclosomatostatin does not contain a radionuclide. It is a non-selective somatostatin receptor antagonist, [36] inhibiting the effects of somatostatin on target cells in the gastrointestinal (GI) tract, pancreas, hypothalamus, and central nervous system (CNS). [2]
In both species, the peptide hormone Urocortin III (Ucn3) is a major local signal that is released from beta cells (and alpha cells in primates) to induce the local secretion of somatostatin. [3] It has also been suggested that somatostatin may be implicated in insulin-induced hypoglycaemia through a mechanism involving SGLT-2 receptors.
Beta cells are specialized cells in the pancreas that produce and release the hormone insulin, which helps regulate blood sugar levels. People with type 2 diabetes have a weakened beta-cell ...
Somatomedin C, Human. Somatomedins are a group of proteins produced predominantly by the liver when growth hormones act on target tissue. Somatomedins inhibit the release of growth hormones by acting directly on anterior pituitary and by stimulating the secretion of somatostatin from the hypothalamus.
