Gene Information

General description

The somatostatin gene codes for a peptide hormone containing 14 and 28 amino acid moieties. SST-14 is highly expressed in the central nervous system and peripheral organs. SST-28 is mainly expressed in enteroendocrine cells of the intestine.

Biochem/physiol Actions

NK-1 tachykinin receptor antagonist
Somatostatin plays an important role in regulating the metabolism of other hormones such as growth hormone, insulin, IGF-1 (insulin-like growth factor 1), glucagon, glucagon-like peptide and gastrin. Somatostatin has both regulatory and inhibitory functions. It retards gastrointestinal motility and gallbladder contraction, suppresses gut exocrine secretion and reduces epithelial proliferation. Somatostatin is associated with intestinal nutrient absorption and blood flow regulation. This peptide hormone is believed to inhibit cell proliferation and promote apoptosis. Somatostatin acts as a neurotransmitter and neuromodulator, and is also associated in maintaining water balance.

Obesity is a risk factor for poor outcomes after trauma, and circulating levels of ghrelin are decreased in obese patients. We hypothesized that ghrelin modifies microvascular permeability. The purposes of this study were to determine (1) the effect of ghrelin

Mitogenic stimulation of Swiss 3T3 fibroblasts with bombesin results in receptor-mediated activation of a complex array of effectors, including phospholipase C beta and mitogen-activated protein (MAP) kinase. Incubation of Swiss 3T3 fibroblasts with the 11-amino acid [D-Arg1,D-Phe5,D-Trp7,9,Leu11]substance P peptide inhibited

The effect of peptide and nonpeptide substance P antagonists on prolactin (PRL) and growth hormone (GH) secretion was evaluated in three-dimensional rat anterior pituitary cell aggregates. [D-Arg1,D-Phe5,D-Trp7,9,Leu11]Substance P inhibited basal growth hormone (GH) release at a concentration range of 1-10
