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 ...
Somatostatin: Pancreatic δ Cells: 1) Suppresses glucagon release from α cells (acts locally); 2) Suppresses release of Insulin, Pituitary tropic hormones, gastrin and secretin. 3) Decreases stomach acid production by preventing the release of other hormones (gastrin and histamine), thus slowing down the digestive process.

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.
Octreotide, sold under the brand name Sandostatin among others, is an octapeptide that mimics natural somatostatin pharmacologically, though it is a more potent inhibitor of growth hormone, glucagon, and insulin than the natural hormone. It was first synthesized in 1979 and binds predominantly to the somatostatin receptors SSTR2 and SSTR5. [5]
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 ...
Thus, the improvement in insulin sensitivity that comes with HRT is good news, as it could have a protective effect against diabetes. “Hormone replacement therapy, including estrogen and ...
