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.
[2] [4] [9] Another topic of interest for beta-cell physiologists is the mechanism of insulin pulsatility which has been well investigated. [41] [42] Many genome studies have been completed and are advancing the knowledge of beta-cell function exponentially. [43] [44] Indeed, the area of beta-cell research is very active yet many mysteries remain.
The 99m Tc product is supplied as a kit with two vials, one containing the chelating agent ethylenediaminediacetic acid (EDDA) and the other the HYNIC-Tyr3-octreotide chelator and somatostatin analog. [13] Approximately 400-700 MBq may be administered, with imaging at 2, 4, and occasionally 24 hours post administration.

Somatostatin receptor type 5 is a protein that in humans is encoded by the SSTR5 gene. [5] Somatostatin acts at many sites to inhibit the release of many hormones and other secretory proteins. The biological effects of somatostatin are probably mediated by a family of G protein-coupled receptors that are expressed in a tissue-specific manner.
The biological effects of somatostatin are probably mediated by a family of G protein-coupled receptors that are expressed in a tissue-specific manner. The encoded protein is a member of the superfamily of somatostatin receptors having seven transmembrane segments, and is expressed in highest levels in jejunum and stomach. [6]
The somatostatin hormone itself can negatively affect the uptake of hormones in the body and may play a role in some hormonal conditions. Somatostatin 2 receptors have been found in concentration on the surface of tumor cells, particularly those associated with the neuroendocrine system where the overexpression of somatostatin can lead to many complications [22] [23] Due to this, these ...
