Abstract

Previous studies demonstrated that the transforming growth factor (TGF) β superfamily, including TGF-βs and bone morphogenetic proteins (BMPs), plays important roles in cardiovascular diseases. The kielin/chordin-like protein (KCP) is a secreted protein that regulates the expression and function of TGF-βs and BMPs. However, the role of KCP during heart failure (HF) remains unknown. The present study aimed to investigate the cardiac expression of KCP in human failing hearts. The human failing heart samples from patients with dilated cardiomyopathy (DCM, n = 12) and ischemic cardiomyopathy (ICM, n = 12) were collected, and normal heart (n = 8) samples from unmatched donors were collected as controls. Collagen volume, KCP levels, and mRNA levels of several BMPs in left ventricles (LV) of all hearts were measured. The KCP levels were significantly higher in human failing hearts than in normal hearts. KCP levels were positively associated with hypertrophy markers, including atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP) and β-myosin heavy chain (β-MHC). In addition, KCP levels were also positively associated with left ventricular end-diastolic dimension (LVEDD), collagen Iα and collagen IIIα expression but were ne...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
