Abstract

(Figure presented.) α-Melanocyte-stimulating hormone (α-MSH) regulates several physiological functions by interacting with melanocortin receptors (MC1-R–MC5-R). This study shows that α-MSH is expressed in the heart and it protects against pathological cardiac remodeling by activating MC5-R in cardiomyocytes. α-MSH production declines in the failing mouse heart. Pharmacological administration of α-MSH alleviates pathological cardiac hypertrophy induced by pressure overload. The protective effects of α-MSH are mediated by the melanocortin 5 receptor (MC5-R), which is expressed in mouse and human cardiac myocytes. Silencing MC5-R in cardiomyocytes renders mice susceptible to cardiac hypertrophy and fibrosis after pressure overload.
