Inhibition of kinin metabolism and the role of the vascular B₁ kinin receptor in patients with congestive heart failure [PDF]

, 2008
BACKGROUND Angiotensin-converting enzyme and neutral endopeptidase are endothelial metallopeptidases that metabolise bradykinin. Inhibitors of angiotensinconverting enzyme improve symptoms and survival in patients with heart failure and vascular ...

Mechanical Stress Induced NOX2 Promotes Endothelial Dysfunction in Ventilator‐Induced Lung Injury: Potential Treatment with Quercetin

Advanced Science, EarlyView.
Abnormal mechanical stretch induced by mechanical ventilation (MV) disrupts endothelial junctions via the NOX2/ROS/CaMKII/ERK1/2 axis both in human aortic endothelial cells (HAECs) in vitro and in ventilator‐induced lung injury (VILI) in mice. Quercetin, an antioxidant predicted to bind to NOX2, can effectively prevent mechanical stretch‐induced ...

Enzyme localization can drastically affect signal amplification in signal transduction pathways [PDF]

, 2007
Push-pull networks are ubiquitous in signal transduction pathways in both prokaryotic and eukaryotic cells. They allow cells to strongly amplify signals via the mechanism of zero-order ultrasensitivity. In a push-pull network, two antagonistic enzymes control the activity of a protein by covalent modification.

Angiotensin Blockade in Patients with Diabetic Nephropathy [PDF]

, 2007
When used to delay the progression of early nephropathy in patients with type 2 diabetes mellitus, angiotensin receptor blockers (ARBs) are not superior to angiotensin-converting enzyme (ACE) inhibitors.

Immunohistochemical expression of intrarenal renin angiotensin system components in response to tempol in rats fed a high salt diet [PDF]

, 2017
AIM:To determine the effect of tempol in normal rats fed high salt on arterial pressure and the balance between antagonist components of the renal renin-angiotensin system.METHODS:Sprague-Dawley rats were fed with 8% NaCl high-salt (HS) or 0.4% NaCl ...

Neutrophil–Endothelium Interaction Mediated by S100A9 Promotes Pulmonary Vascular Remodeling During Pulmonary Hypertension

Advanced Science, EarlyView.
This study investigates the critical mechanisms underlying pulmonary hypertension progression, with a focus on the novel role of neutrophil‐derived S100A9 in endothelial dysfunction‐mediated pulmonary vascular remodeling. By integrating human lung samples, multi‐omics analyses, animal models, and mechanistic in vitro studies, it is revealed that how ...

Astrocytic ET‐1 System Determines Microglia Phenotype Following Spinal Cord Injury

Advanced Science, EarlyView.
The study reveals that astrocytic ET‐1 system is solely activated by thrombin following SCI via RhoA/NF‐κB and MAPKs/NF‐κB signal pathway. The release of astrocytic ET‐1 drives microglia polarization toward M1 phenotype through YAP signaling via ETA and ETB receptors.
