Crosstalk between beta‐adrenergic and insulin signaling mediates mechanistic target of rapamycin hyperactivation in liver of high‐fat diet‐fed male mice

Physiological Reports, 2021
Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease. While increased nutrient intake and sympathetic activity have been associated with the disease, the pathogenesis of NAFLD remains incompletely understood.

Decreased RYR2 Cluster Size and Abnormal SR Ca2+ Release Contribute to Arrhythmogenesis in TMEM43‐Related ARVC

Advanced Science, EarlyView.
The TMEM43 ‐ P386S mutation causes arrhythmogenic right ventricular cardiomyopathy (ARVC) by mislocalizing itself from nuclear envelope (NE) to cytoplasm, disrupting lamin B2 (a novel TMEM43 interactor) localization, NE integrity and chromatin accessibility, causing hyper ‐ phosphorylation and reduced expression/clustering of ryanodine receptor type 2 (

High affinity binding of beta-adrenergic receptor kinase to microsomal membranes. Modulation of the activity of bound kinase by heterotrimeric G protein activation.

Journal of Biological Chemistry, 1996
The beta-adrenergic receptor kinase (beta ARK) modulates beta-adrenergic and other G protein-coupled receptors by rapidly phosphorylating agonist-occupied receptors at the plasma membrane.

Targeted 2‐Deoxy‐D‐Ribose Delivery by Biomimetic Nanoplatform Activates EGFR for Accelerated Heart Valve Endothelialization

Advanced Science, EarlyView.
This study develops a biomimetic nanoplatform using erythrocyte membrane‐camouflaged, CD144 antibody‐functionalized nanoparticles to deliver 2‐deoxy‐D‐ribose (2dDR). This system promotes heart valve endothelialization by enhancing endothelial cell migration and proliferation via EGFR activation, while improving hemocompatibility.

Association of the ADRB2 rs1042714 variant with retinopathy of prematurity highlights the importance of the renin-angiotensin-aldosterone system

Scientific Reports
Retinopathy of prematurity (ROP) remains a leading cause of childhood blindness globally. The clinical progression of ROP exhibits notable similarities to infantile hemangioma (IH), suggesting shared risk factors and underlying mechanisms.

Stimulation of β-adrenergic receptors plays a protective role via increased expression of RAF-1 and PDX-1 in hyperglycemic rat pancreatic islet (RIN-m5F) cells

Archives of Medical Science, 2016
Introduction : It is a widely held view that a progressive reduction of beta-cell mass occurs in the progression of diabetes. RAF-1 kinase and pancreas duodenal homeobox 1 (PDX-1) are major factors that promote survival of cells and maintain normal ...

α1A Adrenoreceptor blockade attenuates myocardial infarction by modulating the integrin-linked kinase/TGF-β/Smad signaling pathways

BMC Cardiovascular Disorders, 2023
Background Myocardial infarction (MI) is considered a public health problem. According to the World Health Organization, MI is a leading cause of death and comorbidities worldwide. Activation of the α1A adrenergic receptor is a contributing factor to the

Endothelium‐Independent Relaxation of Alkaloid Boldine in Isolated Aortas From Normotensive and Hypertensive Rats: Participation of Ca2+ Channels

Chemistry &Biodiversity, EarlyView.
Involvement of Ca2+ channels in boldine‐induced vascular relaxation. ABSTRACT The regulation of vascular tone plays a fundamental role in blood pressure homeostasis and still represents a significant challenge in clinical practice. Boldine, a naturally occurring alkaloid from Peumus boldus, has emerged as a compound of interest due to its therapeutic ...

Targeting cardiac beta-adrenergic signaling via GRK2 inhibition for heart failure therapy

Frontiers in Physiology, 2013
Cardiac cells, like those of the other tissues, undergo regulation through membrane-bound proteins known as G protein-coupled receptors (GPCRs). β-adrenergic receptors (βARs) are key GPCRs expressed on cardiomyocytes and their role is crucial in cardiac
