| Outline of Final Research Achievements |
Pituitary adenylate cyclase-activating polypeptide (PACAP) is a multifunctional neuropeptide. Although the heart has VIP and PACAP signaling systems including the ligand and receptors, however, involvement of PACAP in cardiac hypertrophy and subsequent heart failure are still unknown. Recently,VIP and PACAP have been reported to have cardioprotective effect and be associated with heart failure.
In this study, elevated PACAP signaling was associated in hypertrophic right ventricles and heart failure induced with monocrotaline in rats. In addition, intravenous administration of PACAP but not VIP improved cardiac output. Therefore,PACAP may play an important roles in right cardiac hypertrophy. However, further study will be necessary to clarify the role in detail and the mechanism.
