Calcitonin gene-related peptide in noradrenergic transmission in rat hypothalamus.

Calcitonin gene-related peptide in noradrenergic transmission in rat hypothalamus.

In the present study, we examined the regulatory mechanisms of calcitonin gene-related peptide on norepinephrine release in rat hypothalamus. Calcitonin gene-related peptide inhibited the stimulation-evoked norepinephrine release from hypothalamic slices of Sprague-Dawley rats in a dose-dependent manner, although the peptide did not affect basal release of norepinephrine. The blockade of the al...

Comparison between Brain Natriuretic Peptide and Calcitonin Gene Related Peptide in Children with Dilated Cardiomyopathy

Background: Dilated cardiomyopathy (DCM) is revealed with the left ventricular dilatation and systolic dysfunction. This study was performed to determine the level of Calcitonin Gene Related Peptide (CGRP) and Brain Natriuretic Peptide (BNP) in children with dilated cardiomyopathy and controls and comparison of these two biomarkers in patients. Materials and Methods: This case-control study was...

Calcitonin gene related peptide.

Calcitonin Gene-Related Peptide (CGRP)

Calcitonin gene-related peptide (CGRP) is a 37 amino acid vasoactive neuropeptide that is widely distributed in central and peripheral nervous systems in mammals. CGRP was discovered in 1982 by molecular cloning of calcitonin (CT) gene. CGRP-specific mRNA appears to predominate in the hypothalamus while CT mRNA predominates in the thyroid. CGRP has an amphiphilic α-helical secondary structure i...

Solution structures of calcitonin-gene-related-peptide analogues of calcitonin-gene-related peptide and amylin.

Near-u.v. and far-u.v. c.d. spectra of human alpha-calcitonin-gene-related peptide (h alpha CGRP), analogues and fragments of CGRP and amylin were recorded in aqueous solution and in trifluoroethanol (TFE)/water mixtures. All peptides contained significant amounts of alpha-helix in aqueous solution, and this amount increased on adding TFE. The helical content was unaffected by pH and salt. Howe...
