Summary: Elevated plasma levels of soluble (pro)renin receptor (s(P)RR) are associated with edema in symptomatic heart failure patients with reduced ejection fraction, independent of renal dysfunction. This finding is consistent with observations in mice with dilated cardiomyopathy and heart failure with reduced ejection fraction.

Summary: The study highlights the role of sPRR as a ligand for AT1R, causing endothelial dysfunction and hypertension. The interaction between sPRR and AT1R contributes to obesity-induced cardiovascular diseases. The sPRR/AT1R complex may be a potential therapeutic target for endothelial dysfunction.

Summary: (Pro)renin receptor (PRR) is a component of the renin-angiotensin system (RAS) and is involved in the pathogenesis of cardiovascular diseases. This review focuses on the effects of PRR and its soluble form on various cardiovascular conditions, including hypertension, myocardial ischemia reperfusion injury, heart failure, metabolic cardiomyopathy, and atherosclerosis.

Summary: Loss of sPRR reduces baseline blood pressure, decreases Ang II-induced hypertension and renal injury, and is associated with greater endothelium-dependent vasorelaxation of resistance-sized arteries.

Summary: The study found that PRR is associated with the development and progression of renal tumors, with high expression at the tumor center and infiltrative front being significantly correlated with high grade, tumor diameter, local invasion, and stage, as well as high mortality risk. The potential of PRR as a novel biomarker for RCC diagnosis/prognosis and as a promising therapeutic target should be considered for the future.

Summary: The (P)RR and s(P)RR play important roles in pregnancy and have potential as biomarkers for pregnancy complications. Further research is needed to understand their functions in pregnancy and their dysregulation's contribution to complications. Soluble (P)RR levels could be indicative of placental, kidney or liver dysfunction and may serve as novel clinical biomarkers or therapeutic targets for improving the detection and treatment of pregnancy pathologies.

Summary: (Pro)renin receptor (PRR) plays a crucial role in renal pathophysiology by binding and activating renin. Recent studies have shown that soluble PRR (sPRR) mediates the pathological functions of PRR in the kidney.

Summary: This study reveals a novel mechanism by which PRR and sPRR negatively regulate NCC activity through S1P, impacting renal excretion of salt and potassium and thus modulating blood pressure and potassium balance.

Summary: Chronic kidney disease (CKD) is associated with advanced oxidation protein products (AOPPs). A recent study investigated the role of the (pro)renin receptor (PRR) in AOPP-induced renal damage in rats. The study found that the PRR inhibitor PRO20 can protect against AOPP-induced nephropathy by inhibiting intrarenal renin-angiotensin system (RAS) and Nox4-derived H2O2 mechanisms.

Summary: Inhibiting hepatic (P)RR can effectively reduce plasma cholesterol and triglyceride concentrations, but does not necessarily decrease atherosclerosis development. Transcriptomic analysis in the aortas revealed increased expression of genes related to immune responses and inflammation with (P)RR inhibition, while downregulating (P)RR in macrophages enhanced inflammatory responses and accelerated atherosclerosis.

Summary: Cardiovascular diseases are major public health problems globally and the activation of the (Pro)renin receptor (PRR) plays a significant role in cardiovascular homeostasis. PRR activation is associated with myocardial ischemia/reperfusion injury, cardiac hypertrophy, heart failure, vascular smooth muscle cell proliferation, endothelial cell dysfunction, and the progression of vascular diseases. Targeting PRR may have benefits for patients with cardiovascular diseases.

Summary: The study showed that inhibition of central PRR expression can ameliorate salt-induced renal injury in CKD rats by reducing sympathetic nerve activity, inflammation, and oxidative stress, as well as by blocking central MAPK/ERK1/2 and PI3K/Akt signaling pathways and ACE1-Ang II-AT1R axis. This suggests that targeting central PRR or PRR-mediated signaling pathway may be a novel strategy for CKD treatment.

Summary: The (pro)renin receptor (P)RR has important roles in the kidney and brain, independently of prorenin, in activating inflammatory and fibrotic responses in renal dysfunction and being linked to hypertension in the brain. By regulating pH and function of v-ATPase, (P) RR plays crucial roles in cellular homeostasis and autophagy in kidney, brain, and heart.

Summary: Cancer is a major global public health problem that affects hundreds of millions of people worldwide, and currently lacks reliable biomarkers for predicting its clinical outcomes. Recent research has shown that (pro)renin receptor (PRR) acts as a novel biomarker in various types of cancer. This review summarizes the current understanding of PRR in cancer, including its expression levels in different cancers, potential mechanisms in cancer progression, and its role in cancer treatment.

Summary: In the formalin pain test, the EM-2 analogs EM-2-Me, EM-2-Et, and EM-2-Bu showed significant analgesic effects with reduced tolerance and gastrointestinal side effects. These effects were mediated through central opioid mechanisms, with EM-2-Me possibly involving dynorphin A release and EM-2-Bu directly activating multiple opioid receptors.
