Galanin receptors (provisional nomenclature as recommended by NC-IUPHAR [57]) are activated the endogenous peptides galanin and galanin-like peptide. Human is a 30 amino-acid non-amidated peptide [52]; in other species, it 29 amino acids long C-terminally amidated. Amino 1-14 of highly conserved mammals, birds, reptiles, amphibia fish. Shorter species (e.g. human galanin-1-19 [21] porcine galan...

Galanin and the N-terminal fragment Galanin(1-15) are involved in central cardiovascular regulation. The present paper reviews the recent cardiovascular results obtained by intracisternal injections of Galanin and Galanin(1-15) showing that: (A) the Galanin antagonist M40 blocks the central cardiovascular responses induced by Galanin(1-15) but not those elicited by Galanin; (B) both Galanin and...

The galanin family currently consists of four peptides, namely galanin, galanin-message associated peptide, galanin-like peptide and alarin. Unlike galanin that signals through three different G protein-coupled receptors; GAL1, GAL2, and GAL3, binding at its N-terminal end, the cognate receptors for other members of the galanin family are currently unknown. Research using short N-terminal galan...

This study investigated the effects of five levels of galanin on plasma concentrations of growth hormone, triiodothyronine, thyroxine, and milk protein in dairy goat breed was sannan. 15 breeds of dairy goats sannan all about the same age and weight were selected for this study and were randomly divided into five treatments (three replicates per treatment). Levels of the hormone injection of ga...

Estrogen is a robust stimulator of galanin synthesis and secretion in the anterior pituitary. Galanin is colocalized in lactotrophs in the estrogen-treated anterior pituitary, and its roles in lactotroph function are still being elucidated. In the present studies, we quantified the phenotypes of estrogen-treated Fischer 344 rat anterior pituitary cells expressing the galanin gene by dual in sit...

Galanin mRNA and peptide are not detectable in normal islets. We studied the effect of galanin antagonists on insulin secretion in the rat beta cell line, RIN5AH, and in perifused rat islets. In RIN cell membranes galanin and its antagonists showed high affinity for 125I-galanin binding sites [Kd: (galanin) 0.03+/-0.01; Ki for galanin antagonists: (C7) 0.12+/- 0.02, (M35) 0.21+/-0.04, and (M40)...

It has been demonstrated previously that central administration of the N-terminal galanin fragment (1-15) elicits hypertension and tachycardia and antagonizes the hypotensive effect of the parent molecule galanin-(1-29). In order to further clarify the role of galanin in central cardiovascular control, the possible modulation of the baroreceptor reflex by both galanin molecules has been studied...

The distribution of galanin-containing nervous elements in the chicken pancreas was investigated by use of immunohistochemical method. Galanin-immunoreactive nerve fibres formed a perivascular plexus and a dense network in the subepithelial layer of secretory ducts. The muscle layers of secretory ducts were also supplied with galanin-immunoreactive nerve fibres. The exocrine pancreas received a...
