somatostatina 28

Descrizione:

somatostatina 28 è un ormone peptidico che svolge un ruolo cruciale nella regolazione di vari processi fisiologici, inclusa l'inibizione del rilascio dell'ormone della crescita e la modulazione della secrezione di insulina e glucagone. È un membro della famiglia della somatostatina, che consiste in diverse isoforme, con somatostatina 28 che è una delle forme più lunghe, derivata dal precursore preprosomatostatina. Questo peptide è composto da 28 aminoacidi ed espone una struttura ciclica che contribuisce alla sua stabilità e attività biologica. somatostatina 28 è prodotto principalmente nell'ipotalamo e nel tratto gastrointestinale, dove agisce su recettori specifici per esercitare i suoi effetti. Le sue funzioni si estendono al sistema nervoso centrale, dove influenza la neurotrasmissione e la segnalazione neuroendocrina. Il numero CAS 73032-94-7 identifica univocamente questo composto nelle banche dati chimiche, facilitando la ricerca e l'applicazione in farmacologia e biochimica. In generale, somatostatina 28 è significativo sia in contesti clinici che di ricerca, in particolare nella comprensione della regolazione ormonale e delle potenziali applicazioni terapeutiche nei disturbi endocrini.

Somatostatin-28

CAS: 73032-94-7

The octacosapeptide somatostatin-28 arises from the posttranslational cleavage of prosomatostatin, which in turn is derived from a larger precursor, preprosomatostatin. S-28 was first isolated from porcine duodenum. In guinea-pig pancreatic acini, S-28, unlike S-14, increased amylase secretion, cellular cyclic GMP, and Ca²⁺ outfluxes.

Somatostatin-28

CAS: 73032-94-7

Somatostatin-28 H-Ser-Ala-Asn-Ser-Asn-Pro-Ala-Met-Ala-Pro-Arg-Glu-Arg-Lys-Ala-Gly (Disulfide bond) is a peptide hormone that is produced in the body by different tissues, including the pancreas. Somatostatin inhibits the release of various hormones, including growth hormone and insulin. It also has been shown to inhibit cell proliferation, tumor growth and angiogenesis in vitro. Somatostatin is used to diagnose diseases such as acute pancreatitis, chronic pancreatitis and prostate cancer. The somatostatin analog octreotide has been shown to reduce symptoms of diarrhea in patients with AIDS.

Somatostatin-28

CAS: 73032-94-7

Somatostatin-28 is the 28 amino acid isoform of somatostatin and has similar activity to the 14 amino acid isoform. While the 14 amino acid form mainly acts in the brain, somatostatin-28 mainly operates in the gastrointestinal tract. Somatostatin is a peptide hormone that is widely expressed throughout the body for example in the gastrointestinal (GI) tract, hypothalamus, pancreas and the central nervous system. It has been found to inhibit pituitary growth hormone release as well as endocrine, pancreatic and GI secretions. In the central nervous system somatostatin plays a role in neurotransmission modification and it has also demonstrated to be effective against a number of cancers such as squamous carcinoma.
