Role of G-protein-coupled receptor kinase 4 on the dysfunction of renal Mas receptor in hypertension.

ABSTRACT: The angiotensin converting enzyme 2/angiotensin-(1-7)/Mas receptor axis plays an important role in the regulation of blood pressure. G protein-coupled receptor kinase 4 (GRK4) has attracted more attentions by modulating G protein-coupled receptors and blood pressure. However, it remains unknown whether renal Mas receptor is regulated by GRK4 and its role in the pathogenesis of hypertension. Compared with Wistar-Kyoto (WKY) rats, spontaneously hypertensive rats (SHRs) exhibited impaired Mas receptor-mediated diuresis and natriuresis, which was accompanied with increased phosphorylation levels of Mas receptors. Similarly, the phosphorylation of renal Mas receptor was increased and its-induced renal effects were decreased in human (h) GRK4γ 142V transgenic mice relative to wild-type littermat
