Somatostatin Analogs Inhibit Somatostatin Release*

Endocrinology, 1979
To determine if, like insulin, somatostatin inhibits its own secretion from the pancreas, nonimmunoreactive analogs of somatostatin were perfused in an isolated dog pancreaticoduodenal preparation using a nonrecirculating system. [D-Trp8-D-Cys14]somatostatin, at a concentration of 200 ng/ml, blocked the response of somatostatin-like immunoreactivity ...

Somatostatin analogs

The Journal of Peptide Research, 2001
Abstract:  Somatostatin is a hypothalamic peptide hormone that inhibits the secretion of growth hormone, glucagon, insulin, gastrin and secretin, and also plays a role in neural transmission. Because of its wide range of possible clinical applications hundreds of somatostatin analogs have been synthesized and bioassayed to date.

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 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, 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 Receptors

Trends in Endocrinology and Metabolism, 1985
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.
