Somatostatin receptor type 5 modulates somatostatin receptor type 2 regulation of adrenocorticotropin secretion.

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 ...

Nonpeptide somatostatin receptor agonists specifically target ocular neovascularization via the somatostatin type 2 receptor.

PURPOSE To define the molecular pharmacology underlying the antiangiogenic effects of nonpeptide imidazolidine-2,4-dione somatostatin receptor agonists (NISAs) and evaluate the efficacy of NISA in ocular versus systemic delivery routes in ocular disease models. METHODS Functional inhibitory effects of the NISAs and the somatostatin peptide analogue octreotide were evaluated in vitro by chemot...

Mutation of somatostatin receptor type 5 in an acromegalic patient resistant to somatostatin analog treatment.

Introduction of somatostatin analogs has greatly contributed to improving the prognosis of acromegaly. Although the majority of patients are effectively treated by these agents, resistance occurs in a subset of patients. So far, resistance to somatostatin has never been associated with mutations of the somatostatin receptor subtypes (sst2 and sst5) that inhibit GH secretion. Molecular analysis ...

The multi-ligand somatostatin analogue SOM230 inhibits ACTH secretion by cultured human corticotroph adenomas via somatostatin receptor type 5.

OBJECTIVE Currently, there is no effective medical treatment for patients with pituitary-dependent Cushing's disease. A novel somatostatin (SS) analogue, named SOM230, with high binding affinity to SS receptor subtypes sst(1), sst(2), sst(3) and sst(5) was recently introduced. We compared the in vitro effects of the sst(2)-preferring SS analogue octreotide (OCT) and the multi-ligand SOM230 on A...

Noninvasive monitoring of somatostatin receptor type 2 chimeric gene transfer.

UNLABELLED Noninvasive monitoring of gene transfer will benefit basic research and patient care. Most gene-transfer imaging systems do not directly detect the gene of interest, and most do not exploit radiopharmaceuticals that have Food and Drug Administration approval for total-body use. (111)In-Octreotide is used clinically to locate tumors overexpressing primarily somatostatin receptor type ...
