Targeting GPR39 in structure-based drug discovery reduces Ang II-induced hypertension.

ABSTRACT: The endothelium-dependent vascular injury, a primary pathological feature of angiotensin II (Ang II)-induced hypertension. This study aimed to explore the role and underlying mechanisms of G protein-coupled receptor 39 (GPR39) in the pathogenesis of Ang II-induced hypertension. For in vivo studies, GPR39 knockout (KO) mice (C57BL/6 J, male) were generated and administered Ang II for 4 weeks. GPR39 expression was upregulated in the aorta of hypertensive patients and mice. The ablation of GPR39 mitigated vascular fibrosis, augmented endothelium-dependent vasodilation, and inhibited endothelial inflammation, oxidative stress, and apoptosis in mice. Additionally, GPR39 KO decreased NOD-like receptor protein 3 (Nlrp3) gene expression in Ang II-stimulated endothelial cells. Notably, Nlrp3 activa
