Cardiovascular actions of angiotensin-(1-7)

Brazilian Journal of Medical and Biological Research, 2005
Angiotensin-(1-7) (Ang-(1-7)) is now considered to be a biologically active member of the renin-angiotensin system. The functions of Ang-(1-7) are often opposite to those attributed to the main effector component of the renin-angiotensin system, Ang II ...

Porcine kidney xenotransplantation: From primate models to clinical reality

Animal Models and Experimental Medicine, EarlyView.
In the face of a critical shortage of human donor kidneys for end‐stage renal disease patients, porcine kidney xenotransplantation has emerged as a viable solution. This field has navigated major hurdles, including immune rejection, physiological incompatibilities, potential biomechanical differences and the risk of cross‐species infection. To overcome

Enhanced expression of Ang-(1-7) during pregnancy

Brazilian Journal of Medical and Biological Research, 2004
Pregnancy is a physiological condition characterized by a progressive increase of the different components of the renin-angiotensin system (RAS). The physiological consequences of the stimulated RAS in normal pregnancy are incompletely understood, and ...

An orally active formulation of angiotensin-(1-7) produces an antithrombotic effect

Clinics, 2011
INTRODUCTION AND OBJECTIVE: The heptapeptide angiotensin-(1-7) is a component of the renin-angiotensin system, which promotes many beneficial cardiovascular effects, including antithrombotic activity. We have recently shown that the antithrombotic effect

Animal models of idiopathic membranous nephropathy: Recent advances and future perspectives

Animal Models and Experimental Medicine, EarlyView.
This review focuses on the evolution of idiopathic membranous nephropathy (IMN) animal models from traditional approaches (Heymann nephritis, C‐BSA, APA) to antigen‐specific models (PLA2R, THSD7A), critically evaluating their advances and limitations in replicating human IMN pathology.

Modulation of the renin-angiotensin system against COVID-19: A path forward?

International Journal of Infectious Diseases
Soon after the pandemic outbreak in 2020, it was proposed that binding of SARS-CoV-2 to the angiotensin converting enzyme-2 may explain most of COVID-19’s manifestations.

Effect of Melatonin on the Renin-Angiotensin-Aldosterone System in l-NAME-Induced Hypertension

Molecules, 2018
The renin-angiotensin-aldosterone system (RAAS) is a dominant player in several cardiovascular pathologies. This study investigated whether alterations induced by l-NAME, (NLG)-nitro-l-arginine methyl ester, a nitric oxide synthase inhibitor, and the ...

Chrysin alleviates pressure overload–induced myocardial remodeling through regulating the PI3K/AKT/NRF2 pathway–mediated oxidative stress response

Animal Models and Experimental Medicine, EarlyView.
In this study, we primarily simulated pathological myocardial remodeling induced by transverse aortic constriction surgery and found significant cardiac hypertrophy and fibrosis, characterized by deteriorated cardiac function. Oxidative stress response is considered as a pivotal pathological process, which contributes to inflammation and apoptosis of ...

Idiopathic Intracranial Hypertension Is Characterized by a Distinct Proteomic Profile

Annals of Neurology, EarlyView.
Objectives The pathophysiology of idiopathic intracranial hypertension (IIH) is poorly understood and disease‐specific biomarkers are lacking. We aimed to shed light on IIH pathophysiology and identify disease‐specific biomarkers. Methods This prospective cross‐sectional cohort study included patients with new‐onset IIH and age‐, body mass index‐, and ...
