Somatostatin Receptors

Digestion, 2000
Somatostatin is a neuropeptide produced by neuroendocrine, inflammatory and immune cells in response to different stimuli. Somatostatin inhibits various cellular functions including secretions, motility and proliferation. Its action is mediated by five specific somatostatin receptors (sst1-sst5) which belong to the G protein-coupled receptor family ...

Somatostatin Receptor Manipulation

Digestion, 1996
The expression of somatostatin receptors (ssts) on human tumours is the basis for the successful therapeutic and diagnostic application of (radiolabelled) somatostatin analogues. Manipulation (up-regulation) of sst expression might improve the uptake of radioligand in in vivo scintigraphy of human sst-positive tumours, as well as the potential success ...

Somatostatin receptor imaging

Seminars in Nuclear Medicine, 2002
[(111)In-DTPA(0)]octreotide is a radiopharmaceutical with a great potential for the visualization of somatostatin receptor-positive tumors. The overall sensitivity of Somatostatin Receptor Imaging (SRI) to localize neuroendocrine tumors is high.

Somatostatin receptor SPECT

European Journal of Nuclear Medicine and Molecular Imaging, 2012
Somatostatin is a peptide with a broad distribution in the nervous system and acts as a neurotransmitter in several organs, having a wide range of mainly inhibiting effects, such as the suppression of growth hormone release, as well as the inhibition of pancreatic and gastrointestinal hormone release.

Somatostatin, Somatostatin Receptors, and Pancreatic Cancer

World Journal of Surgery, 2005
AbstractSomatostatin may play an important role in the regulation of cancer growth including pancreatic cancer by interaction with somatostatin receptors (SSTRs) on the cell surface. Five SSTRs were cloned, and the function of these SSTRs is addressed in this review.

Somatostatin and Somatostatin Receptors

2009
The biological effects of somatostatin (SST) were first encountered unexpectedly in the late 1960s in two unrelated studies, one by Krulich et al. (1968) who reported on a growth hormone (GH)-releasing inhibitory substance from hypothalamic extracts, and the other, by Hellman and Lernmark (1969), on the presence of a potent insulin inhibitory factor ...

Somatostatin Receptors

Scandinavian Journal of Gastroenterology, 1986
More insight into the biochemical structure and operation of the somatostatin receptor(s) has been gained in recent years from several approaches. The minimal active structure of the receptor(s) has been identified, and active minisomatostatins have been synthesized.

Somatostatin and Somatostatin Receptor Physiology

Endocrine, 2003
Since the discovery of somatostatin (SST) over three decades ago, its ubiquitous distribution and manifold functions are still being documented. SST is synthesized in the hypothalamus and transported to the anterior pituitary gland where it tonicaly inhibits GH and TSH secretion as well as being responsible for GH pulsatile release.

Somatostatin receptors.

Critical reviews in neurobiology, 1992
The neuropeptide somatostatin (SRIF) is a neurotransmitter in the brain that exerts physiological actions including the modulation of Ca2+ and K+ conductances, neuronal cell firing, neurotransmitter release, and certain behaviors such as locomotion and cognitive functions.

The somatostatin receptor family

Life Sciences, 1995
The diverse biological effects of somatostatin (SST) are mediated through a family of G protein coupled receptors of which 5 members have been recently identified by molecular cloning. This review focuses on the molecular biology, pharmacology, expression, and function of these receptors with particular emphasis on the human (h) homologs.
