Low Dose Chronic Angiotensin II Induces Selective Senescence of Kidney Endothelial Cells

Frontiers in Cell and Developmental Biology, 2021
Angiotensin II can cause oxidative stress and increased blood pressure that result in long term cardiovascular pathologies. Here we evaluated the contribution of cellular senescence to the effect of chronic exposure to low dose angiotensin II in a model ...

Angiotensin II, angiotensin II antagonists and spironolactone and their modulation of cardiac repolarization

, 2005
Angiotensin II and aldosterone produce pro-arrhythmic effects by several mechanisms, including the modulation of voltage-dependent K(+) channels involved in human cardiac repolarization.

GPCRs in CAR‐T Cell Immunotherapy: Expanding the Target Landscape and Enhancing Therapeutic Efficacy

Advanced Science, EarlyView.
Chimeric antigen receptor T cell therapy faces dual challenges of target scarcity and an immunosuppressive microenvironment in solid tumors. This review highlights how G protein‐coupled receptors can serve as both novel targets to expand the therapeutic scope and functional modules to enhance CAR‐T cell efficacy.

Canagliflozin Alleviates Diabetic Glomerular Endothelial Injury via Melibiose in a Microbiota‐Dependent Manner

Advanced Science, EarlyView.
Canagliflozin treatment reshapes the gut microbiota in DKD and elevates levels of melibiose, a metabolite derived from Roseburia intestinalis. Melibiose directly binds to and enhances the enzymatic activity of glyoxalase 1, leading to decreased methylglyoxal accumulation.

Endothelial Vasodilator Angiotensin Receptors are Changing in Mice with Ageing

Research in Molecular Medicine, 2014
Background: The vascular function of Angiotensin II-type-2 receptors in adults is controversial. We sought their location and function in mouse aortic rings at young and old mice.

Renin-Angiotensin-Aldosterone System in Heart Failure: Focus on Nonclassical Angiotensin Pathways as Novel Upstream Targets Regulating Aldosterone [PDF]

, 2019
Aldosterone plays an important role in the regulation of blood pressure, body fluid, and electrolyte homeostasis. Overactivation of aldosterone/mineralocorticoid receptor (MR) pathway leads to hypertension, atherosclerosis, vascular damage, heart failure,

Tailored Porous Bimetallic Nanozyme Platform for Full‐Cycle Therapeutics of Intestinal Ischemia/Reperfusion

Advanced Science, EarlyView.
ABSTRACT Intestinal ischemia/reperfusion (I/R) injury presents a biphasic pathology: an acute oxidative‐inflammatory phase leading to organ failure, and a recovery phase marked by mucosal dysfunction and bacterial translocation. The developed MPB@TA‐Cu‐Ma nanocomposite functions as a dual‐phase therapeutic platform with significant efficacy. It rapidly

Angiotensin II treatment is associated with improved oxygenation in ARDS patients with refractory vasodilatory shock

Annals of Intensive Care, 2023
Background The physiological effects of renin-angiotensin system modulation in acute respiratory distress syndrome (ARDS) remain controversial and have not been investigated in randomized trials. We sought to determine whether angiotensin-II treatment is

Angiotensin II impairs endothelial function via tyrosine phosphorylation of the endothelial nitric oxide synthase

, 2009
Proline-rich tyrosine kinase 2 (PYK2) can be activated by angiotensin II (Ang II) and reactive oxygen species. We report that in endothelial cells, Ang II enhances the tyrosine phosphorylation of endothelial NO synthase (eNOS) in an AT1-, H2O2-, and PYK2-

NSUN5 Attenuates Renal Injury and Ferroptosis in Hyperuricaemic Nephropathy Through YBX2‐Dependent Stabilisation of SCD1 m5C Methylation

Advanced Science, EarlyView.
NSUN5 is downregulated in hyperuricaemic nephropathy. Overexpression of NSUN5 enhances the stability of SCD1 mRNA through the m5C reader YBX2, ultimately inhibiting ferroptosis in renal tubular epithelial cells. Additionally, this axis suppresses the NF‐κB signaling pathway to alleviate inflammation and upregulates ABCG2 to promote uric acid excretion,
