Somatostatin and somatostatin receptors in fish growth
General and Comparative Endocrinology, 2010Multiple forms of somatostatin (SS) and SS receptors (SSTR) are produced widely in the tissues of fish and interact to coordinate numerous physiological processes. Insight into their role in growth regulation emerged from studies of abnormal growth and of whole animals.

It is now well established that the biological actions of tetradecapeptide somatostatin (somatostatin-14, S-14) are receptor-mediated. These receptors were first quantified in GH4C pituitary tumor cells using [125I-Tyr1] S-14 as radioligand which was found to exhibit high non-specific binding to membrane receptor preparations from normal tissues.

Somatostatin induces its biological actions by activating a family of receptor subtypes. The recent cloning of five somatostatin receptor subtypes has led to the development of subtype-selective agonists. These compounds are revealing distinct functions of the individual receptor subtypes.

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 and Somatostatin Receptors
2009The 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 in the Orbits
Clinical Nuclear Medicine, 1995In-111 pentetreotide has been recommended for the detection of somatostatin receptor (SSR) positive tumors. Sites with increased numbers of activated lymphocytes may also show In-111 pentetreotide with Graves' ophthalmopathy (GO) compared to various other orbital disorders.

Somatostatin Receptor Manipulation
Digestion, 2009The 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 ...

Evolutionary history of the somatostatin and somatostatin receptors
Journal of Genetics, 2009Somatostatin and its receptors have a critical role in mammalian growth through their control pattern of secretion of growth hormone, but the evolutionary history of somatostatin and somatostatin receptors are ill defined. We used comparative whole genome analysis of Danio rerio, Carassius auratus, Xenopus tropicalis, Gallus gallus, Monodelphis ...

Somatostatin, Somatostatin Receptors, and Pancreatic Cancer
World Journal of Surgery, 2005AbstractSomatostatin 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 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.
