| Abstract |
BACKGROUND:The (pro)renin receptor [(P)RR)] is involved in the activation of local renin-angiotensin system and subsequent development of cardiovascular disease. We investigated the therapeutic effect of a (P)RR blocker, handle-region peptide (HRP), on chronic kidney disease (CKD)-associated heart failure. METHODS AND RESULTS:CKD was induced in C57BL/6J mice by means of five-sixths nephrectomy. Eight weeks later, cardiac dysfunction and cardiac dilatation with hypertension developed. Mice were then assigned to 1 of the 3 following groups: vehicle, low-dose (0.01 mg·kg-1·d-1) HRP, or high-dose (0.3 mg·kg-1·d-1) HRP for 4 weeks. High-dose HRP treatment reversed left ventricular dilation and significantly improved cardiac dysfunction with ameliorated hypertension compared with the vehicle. The hearts with high-dose HRP treatment showed significant attenuation of cardiac fibrosis, cardiomyocyte hypertrophy, macrophage infiltration, and oxidative DNA damage. This treatment decreased the myocardial expressions of angiotensin (Ang) II, Ang II type 1 receptor, transforming growth factor β1, extracellular matrix-related proteins, and lipid peroxidation. Autophagy was activated in the cardiomyocyte from nephrectomized mice, but HRP treatment had no effect on cardiomyocyte autophagy. CONCLUSIONS:This study indicates that (P)PR blockade is a beneficial strategy by suppressing cardiac fibrosis and hypertrophy to ameliorate heart failure caused by CKD. |
