Adrenomedullin (1-50), rat is a 50 amino acid peptide, which induces a selective arterial vasodilation via activation of CGRP1 receptor.

Adrenomedullin (1-50), rat is a 50 amino acid peptide, which induces a selective arterial vasodilation via activation of CGRP1 receptor[1].

Adrenomedullin (1-50), rat causes a dose-dependent and endothelium-independent vasodilation on the arterial mesenteric vasculature, and this effect is inhibited by CGRP1 receptor antagonist. Adrenomedullin (1-50), rat activates CGRP1 receptor in the double-perfused mesenteric bed of the rat[1]. Adrenomedullin (1-50) ameliorates pulmonary vascular structural remodeling of hypoxic rats with incresed plasma NO and H(2)S concentrations. Adrenomedullin (1-50) also regulates the development of hypoxic pulmonary hypertension and hypoxic pulmonary vascular structural remodeling, through promoting NO and H(2)S production in hypoxic rats[2].
