The vasodilating peptide adrenomedullin (AM) has been reported to regulate vascular tone as well as proliferation and differentiation of various cell types in an autocrine/paracrine manner. Our study was designed to investigate the effect of AM on Ang II-induced contraction on human aortic smooth muscle cells (HASMC) in vitro, evaluating the signal pathways involved. Our findings indicate that AM was able to inhibit HASMC Ang II-induced contraction (IC50 19 nM). AM stimulated cAMP production in a dose-dependent fashion as well. SQ 22.536, an adenylate cyclase inhibitor, and KT5720, a PKA inhibitor, blunted the AM effect, suggesting that it was mediated by the activation of the cAMP transduction pathway. Our results suggest that AM plays a role in the regulation of HASMC contraction by antagonizing the Ang II effects and may be involved in conditions of altered regulation of the blood vessels.
