生物活性

Somatostatin-25 is a endogenous neuropeptide hormone that shows inhibitory activity against secretion of growth hormone.

体外研究
(In Vitro)

Somatostatin-25 (0.1 pM-1 nM) significantly inhibits secretion of growth hormone in the in vitro system, and is 3-14 times more effective than the tetradecapeptide. Somatostatin-25 (0.1 nM-1pM) also inhibits secretion of growth hormone induced by the addition of prostaglandin 2 (PGE2). However, Somatostatin-25 shows no effect on the secretion of prolactin[1].

生物活性

Somatostatin-28 (1-14) is an N-terminal fragment of the neuropeptide somatostatin-28.

体外研究
(In Vitro)

The tetradecapeptide hormone somatostatin arises from proteolytic processing of a large precursor, preprosomatostatin[1]. Somatostatin-28 (1-14) has been used to produce antibodies selective for somatostatin-28 that do not bind to the C-terminal fragment somatostatin-14[2].

生物活性

Somatostatin is a tetradecapeptide which can suppress the growth hormone (GH) secretion and control the pituitary hormone secretion in human CNS.

体外研究
(In Vitro)

Somatostatin is a tetradecapeptide which can suppress the growth hormone (GH) secretion and control the pituitary hormone secretion in human CNS. Somatostatin has two biologically active forms: the predominant form is the 14 amino-acid long Somatostatin-14 while the more potent form is the amino-terminus extended Somatostatin-28. The biological roles of the two Somatostatin isoforms very strongly overlap and the relative proportions of Somatostatin-14 to Somatostatin-28 vary between different tissues. Somatostatin can reduce adhesion of carcinosarcoma cells to the blood vessels and thus attenuate the metastatic potential of these tumours. Somatostatin can also inhibit monocyte chemotactic migration[1].
