The (pro)renin receptor [(P)RR] has been implicated as a renin/prorenin receptor, and plays a role in local renin angiotensin system activation. Our goal was to investigate whether a transgenic mouse that expresses rat tonin [TGM'(rTon)] can regulate (P)RR mRNA levels. Control (C) and TGM'(rTon) animals were subdivided into the C sham, C MI, TGM'(rTon) sham, and TGM'(rTon) MI groups. The levels of tonin, (P)RR, and renin were determined using RT-PCR mRNA. Tonin activity as determined by RIE was significantly increased in the TGM'(rTon) sham group as compared to the C sham group in the atrium (AT) and right ventricle (RV), respectively...

Since the prorenin receptor (PRR) was first reported, investigations into its role in many cellular processes have been underway. Renin and prorenin binding to PRR and its soluble form (sPRR) increases angiotensin I formation and intracellular pathways resulting in induction of profibrotic factors. The PRR has supplementary roles as a vital accessory protein of the vacuolar-type H+-ATPase and also as an intermediate in Wnt signaling. As a component of the H-ATPase, the PRR has been found upregulated during cardiac stress...

Aims: Renal renin-angiotensin system (RAS) plays a pivotal role in the development of diabetic nephropathy (DN). Angiotensin II (Ang II) type 1 receptor (AT1R) blockade elevates (pro)renin, which may bind to (pro)renin receptor (PRR) and exert receptor-mediated, angiotensin-independent profibrotic effects. We therefore investigated whether PRR activation leads to the limited anti-fibrotic effects of AT1R blockade on DN, and whether PRR inhibition might ameliorate progression of DN. Methods: To address the issue, the expression of RAS components was tested in different stages of streptozotocin (STZ)-induced diabetic rats (6, 12, and 24 weeks) and 6-week AT1R blockade (losartan) treated diabetic rats...

Women with preexisting or gestational diabetes mellitus have an increased risk for developing preeclampsia. Diabetes and pregnancy are both characterized by very high prorenin levels and renin-angiotensin system activation. Prorenin bound to the (pro)renin receptor has enzymatic activity. We hypothesized that soluble (pro)renin receptor levels are elevated in high-risk pregnancies. Third trimester maternal blood samples from complicated pregnancies (n = 165), (preeclampsia [n = 76], diabetes mellitus [type I diabetes, n = 35; type II diabetes, n = 11; gestational diabetes mellitus, n = 43]), and healthy pregnancies (n = 49) were analyzed for prorenin, renin, and soluble (pro)renin receptor...

We hypothesized that PRR contributes to renal inflammation in the 2-kidney, 1-clip (2K1C) renal ischemia model. Male Sprague-Dawley rats were fed normal sodium diet. BP was obtained on day 0 and 28 after left renal artery clipping that reduced renal blood flow by 40%. Renal expression of TNF-α, COX-2, NF-κB, IL-1β, MCP-1 and collagen type I were assessed in sham and 2K1C rats with or without left renal administration of scramble or PRR shRNA. At baseline, there were no differences in BP. Compared to sham, MAP significantly increased in clipped animals (sham: 102± 1...

BACKGROUND: Prostaglandin E2 (PGE2) regulates renin expression in renal juxtaglomerular cells. PGE2 acts through E-prostanoid (EP) receptors in the renal collecting duct (CD) to regulate sodium and water balance. CD cells express EP1 and EP4, which are linked to protein kinase C (PKC) and PKA downstream pathways, respectively. Previous studies showed that the presence of renin in the CD, and that of PKC and PKA pathways, activate its expression. The (pro)renin receptor (PRR) is also expressed in CD cells, and its activation enhances cyclooxygenase-2 (COX-2) through extracellular signal-regulated kinase (ERK)...

INTRODUCTION: The prorenin (PR) receptor [(P)RR] contributes to the regulation of the tissue renin-angiotensin system (RAS) and Wnt signaling, which is involved in embryogenesis and the pathological progression of malignant tumors and diabetes mellitus. Placental (P)RR is significantly upregulated in placental tissues from preeclamptic women. However, because it cannot be examined during pregnancy, the chronological relationship between the acceleration of tissue RAS and the disease state of hypertensive disorder of pregnancy (HDP) has not been reported...

The stimulation of angiotensin II (Ang II), the effector peptide of renin-angiotensin system, has been reported to increase the expression of vascular endothelial growth factor (VEGF) through the activation of the Ang II type 1 receptor (AT1R). In this study, we investigated whether hyperglycemia (HG, 33 mM glucose) in ARPE-19 cells could promote the expression of VEGF independently of Ang II through prorenin receptor (PRR), via an NADPH oxidase (Nox)-dependent mechanism. ARPE-19 cells were treated with the angiotensin converting enzyme (ACE) inhibitor perindopril to block the synthesis of Ang II...

Augmented intratubular angiotensin (ANG) II is a key determinant of enhanced distal Na+ reabsorption via activation of epithelial Na+ channels (ENaC) and other transporters, which leads to the development of high blood pressure (BP). In ANGII-induced hypertension, there is increased expression of the prorenin receptor (PRR) in the collecting duct (CD), which has been implicated in the stimulation of the sodium transporters and resultant hypertension. The impact of PRR deletion along the nephron on BP regulation and Na+ handling remains controversial...

During the early phase of ANG II-dependent hypertension, tubular PGE2 is increased. Renin synthesis and secretion in the collecting duct (CD) are upregulated by ANG II, contributing to further intratubular ANG II formation. However, what happens first and whether the triggering mechanism is independent of tubular ANG II remain unknown. PGE2 stimulates renin synthesis in juxtaglomerular cells via E-prostanoid (EP) receptors through the cAMP/cAMP-responsive element-binding (CREB) pathway. EP receptors are also expressed in the CD...

Recent studies suggested that activation of the PRR upregulates profibrotic markers through reactive oxygen species (ROS) formation; however, the exact mechanisms have not been investigated in CD cells. We hypothesized that activation of the PRR increases the expression of profibrotic markers through MAPK-dependent ROS formation in CD cells. Mouse renal CD cell line (M-1) was treated with recombinant prorenin plus ROS or MAPK inhibitors and PRR-shRNA to evaluate their effect on the expression of profibrotic markers...

The presence of renin production by the principal cells of the collecting duct has opened new perspectives for the regulation of intrarenal angiotensin II (Ang II). Angiotensinogen (AGT) and angiotensin-converting enzyme (ACE) are present in the tubular fluid coming from the proximal tubule and collecting duct. All the components needed for Ang II formation are present along the nephron, and much is known about the mechanisms regulating renin in juxtaglomerular cells (JG); however, those in the collecting duct remain unclear...

Recent studies have supported an important contribution of prorenin (PR) and its receptor (PRR) to the regulation of hypothalamic, sympathetic, and neurosecretory outflows to the cardiovascular system, including systemic release of vasopressin (VP), both under physiological and cardiovascular disease conditions. Still, the identification of precise cellular mechanisms and neuronal/molecular targets remain unknown. We have recently shown that PRR is expressed in VP neurons and that their activation increases neuronal activity...

The receptor-associated prorenin system (RAPS) refers to the pathogenic mechanism whereby prorenin binding to the (pro)renin receptor [(P)RR] dually activates the tissue renin-angiotensin system (RAS) and RAS-independent intracellular signaling. Here we revealed significant upregulation of prorenin and soluble (P)RR levels in the vitreous fluid of patients with uveitis compared to non-inflammatory controls, together with a positive correlation between these RAPS components and monocyte chemotactic protein-1 among several upregulated cytokines...

The prorenin receptor was originally discovered as a receptor that binds renin and prorenin, thereby inducing pro-fibrotic intracellular signal cascades. These effects are partially mediated in vitro by angiotensin (ANG) and partially independent of ANG. Consequently, inhibitors of the interaction between the prorenin and the (pro)renin receptor (PRR) were designed hoping that they may prevent fibrotic tissue damage, for instance, in the kidney. However, this concept was challenged by the fact that overexpression of the PRR was not harmful at all, whereas depletion of the PRR was lethal or markedly detrimental...

The renin-angiotensin system (RAS) is undisputedly one of the most prominent endocrine (tissue-to-tissue), paracrine (cell-to-cell) and intracrine (intracellular/nuclear) vasoactive systems in the physiological regulation of neural, cardiovascular, blood pressure, and kidney function. The importance of the RAS in the development and pathogenesis of cardiovascular, hypertensive and kidney diseases has now been firmly established in clinical trials and practice using renin inhibitors, angiotensin-converting enzyme (ACE) inhibitors, type 1 (AT1) angiotensin II (ANG II) receptor blockers (ARBs), or aldosterone receptor antagonists as major therapeutic drugs...

The discovery of the (pro)renin receptor [(P)RR] 15years ago stimulated ideas on prorenin being more than renin's inactive precursor. Indeed, binding of prorenin to the (P)RR induces a conformational change in the prorenin molecule, allowing it to display angiotensin-generating activity, and additionally results in intracellular signaling in an angiotensin-independent manner. However, the prorenin levels required to observe these angiotensin-dependent and -independent effects of the (P)RR are many orders above its in vivo concentrations, both under normal and pathological conditions...

Microglia can transform into proinflammatory/classically activated (M1) or anti-inflammatory/alternatively activated (M2) phenotypes following environmental signals related to physiological conditions or brain lesions. An adequate transition from the M1 (proinflammatory) to M2 (immunoregulatory) phenotype is necessary to counteract brain damage. Several factors involved in microglial polarization have already been identified. However, the effects of the brain renin-angiotensin system (RAS) on microglial polarization are less known...

PURPOSE: MicroRNAs (miRNAs/miRs) are involved in a large number of biological functions and diseases, such as cancer, cardiovascular diseases, and diabetes. MiR-21 has been reported to target Sprouty homolog 1 (SPRY1), SMAD7, and PTEN. In this study, we examined the underlying role of miR-21 in the regulation of prorenin receptor (PRR)-mediated induction of vascular endothelial growth factor (VEGF) expression via targeting SMAD7, SPRY1, and PTEN in a hyperglycemic condition. METHODS: PRR-mediated induction of VEGF under a hyperglycemic condition (high glucose, 33mM) was studied by treating ARPE-19 cells with perindopril (10 µmol/l), which inhibits angiotensin II-mediated signaling...

Even mild abnormalities of the renal structure or function can increase the risk of mortality and complications in other organs. Therefore, safe and effective treatments are necessary in order to influence the progression of renal disease. We used 2 methods to assess the renoprotective effects of aliskiren: 1) a statistical analysis of clinical trials that investigated aliskiren-induced renoprotection, in terms of changes in serum creatinine concentration (sCr) or estimated glomerular filtration rate (eGFR), and, 2) clinical trials that investigated the renoprotective effects of aliskiren with respect to changes in albuminuria or proteinuria...
