Pulmonary arterial hypertension (PAH) leads to pressure overload in the right ventricle (RV) and induces right ventricular hypertrophy (RVH). GPR91 is an orphan G-protein-coupled receptor (GPCR) that has been characterized as a receptor for succinate, which increases in RVH; however, its role remains unknown. We studied succinate-GPR91 signaling in a ...
