Mechanisms Involved in Calcitonin Gene-Related Peptide-Induced Relaxation in Pregnant Rat Uterine Artery1

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 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...

Effect of subarachnoid hemorrhage on calcitonin gene-related peptide-induced relaxation in rabbit basilar artery.

An isometric tension measurement of ring segments was performed in the rabbit basilar and common carotid arteries in vitro to investigate the regional differences in the calcitonin gene-related peptide (CGRP)-induced vasodilation and the effect of subarachnoid hemorrhage on CGRP-induced vasodilation. CGRP elicited vasodilation of the rabbit basilar artery in a dose-dependent fashion when the ar...

Mechanisms of calcitonin gene-related peptide-induced increases of pulmonary blood flow in fetal sheep.

Fetal pulmonary blood flow is regulated by various vasoactive substances. One, calcitonin gene-related peptide (CGRP), increases pulmonary blood flow. We examined four key physiological mechanisms underlying this response using the blocker drugs CGRP receptor blocker (CGRP(8-37)), nitric oxide synthase inhibitor [N(omega)-nitro-L-arginine (L-NNA)], adenosine triphosphate-dependent potassium (K(...
