The diagnostic value of somatostatin receptor scintigraphy (SRS) in detecting tumors has been assessed in a number of studies. We present a 30-year-old female with a history of eight months cough and left shoulder pain. Radiologic evaluation showed pulmonary mass and hepatic lesions, which were pathologically diagnosed as neuroendocrine carcinoma. 99mTc-octreotide scan demonstrated that the pul...
Somatostatin inhibits adrenocorticotropin (ACTH) secretion from pituitary tumor cells. To assess the contribution of somatostatin receptor subtype 5 (SST5) to somatostatin receptor subtype 2 (SST2) action in these cells, we assessed multipathway responses to novel highly monoreceptor-selective peptide agonists and multireceptor agonists, including octreotide and somatostatin-28. Octreotide and ...
Somatostatin is highly expressed in mammalian brain and is involved in many brain functions such as motor activity, sleep, sensory, and cognitive processes. Five somatostatin receptors have been described: sst(1), sst(2) (A and B), sst(3), sst(4), and sst(5), all belonging to the G-protein-coupled receptor family. During the recent years, numerous studies contributed to clarify the role of soma...
The tetradecapeptide somatostatin has been implicated as an important regulator of neuronal and neuroendocrine function in the CNS. The cellular actions of somatostatin are mediated by specific receptors. The genes encoding two different somatostatin receptors (SSTRs) have been isolated and characterized, and RNA blotting studies have shown that both SSTR1 and SSTR2 are expressed in the brain. ...
BACKGROUND & OBJECTIVES Chemotherapy with praziquantel remains the only control measure to Schistosoma mansoni infections to date. The neuropeptide hormone somatostatin gives relief from gastrointestinal disturbances, liverpathology, and reduces egg production in S. mansoni infected mice, suggesting an interaction of somatostatin with the parasite rather than with the host alone. Using antibodi...
