Somatostatin induces translocation of the beta-adrenergic receptor kinase and desensitizes somatostatin receptors in S49 lymphoma cells.

open access: yesJournal of Biological Chemistry, 1987
The beta-adrenergic receptor kinase is a cytosolic enzyme that specifically phosphorylates the agonist-occupied form of the beta-adrenergic receptor (beta AR). Beta AR kinase appears to be translocated from the cytosol to the plasma membrane when kin- S49 lymphoma cells are incubated with either beta-adrenergic agonists or prostaglandin E1, both of ...

Intermittent hypoxia increases lipid insulin resistance in healthy humans: A randomized crossover trial

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
This scheme illustrates the main results of the present study showing an increase in circulating free fatty acids (FFA) that are likely to be related to several mechanisms like decrease in FFA insulin sensitivity and increase in FFA production. Significant changes are labelled in white, and non‐significant or hypothesis are labelled in pale green ...

A beta-adrenergic receptor kinase dominant negative mutant attenuates desensitization of the beta 2-adrenergic receptor.

open access: yesJournal of Biological Chemistry, 1994
The beta-adrenergic receptor kinase (beta ARK) specifically phosphorylates the activated form of the beta 2-adrenergic receptor (beta 2AR) and related G protein-coupled receptors. To further elucidate the role of beta ARK in receptor desensitization, we generated a beta ARK dominant negative mutant by converting an invariant lysine residue in the ...

Effects of Electroacupuncture at ST36 on Visceral Pain and Inflammatory Markers in IBS Rats

open access: yesNeurogastroenterology &Motility, EarlyView.
Electroacupuncture (EA) at ST36 significantly reduced visceral pain and colonic inflammation in IBS model rats. EA increased pain thresholds, lowered AWR scores, and downregulated key inflammatory mediators (IL‐1β, IL‐6, TNF‐α, TRPV1, NF‐κB). These findings highlight ST36‐targeted EA as a promising therapeutic strategy for IBS visceral hypersensitivity

Toll Like Receptor 4: A Potential Link Between Obesity and Metabolic Diseases

open access: yesObesity Reviews, EarlyView.
ABSTRACT Epidemiological evidence shows that obesity increases the risk of developing metabolic diseases. Nevertheless, the mechanisms behind this connection remain underappreciated. The substantial impact of these disorders on global health has led to extensive research efforts aimed at identifying the pathophysiological links between them.

Sex-Dependent Effects of Angiotensin II and Calcineurin in the Vasculature of Mice. [PDF]

open access: yesActa Physiol (Oxf)
ABSTRACT Aim Cardiovascular diseases display strong sex differences. Angiotensin II (AngII) is implicated in this process. The ubiquitously expressed enzymatic beta subunit of calcineurin (PPP3CB), a serine/threonine phosphatase, can mediate pathological effects of AngII in the heart.

Integrative Phosphoproteomic Profiling Reveals Stage‐Specific Signalling and Metabolism in Equine Melanocytic Neoplasm

open access: yesVeterinary and Comparative Oncology, EarlyView.
ABSTRACT Equine melanocytic neoplasms (EMN) are aggressive tumours characterised by high metastatic potential and limited therapeutic options available. However, the molecular mechanisms underlying their progression remain poorly understood. This study therefore presents the integrative phosphoproteomic analysis of EMN tissue, with the aim of ...

Cardiac remodelling in type 2 diabetes: Pathophysiological mechanisms and opportunities for multiscale computational modelling and simulation

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Overview of multiscale cardiac remodelling in type 2 diabetes and how to model and simulate these changes using a human‐based, multiscale computational framework. Cardiac remodelling in type 2 diabetes occurs at ionic channel, protein, cellular, tissue and whole‐organ level, affecting the electrophysiological function, mechanical

Mechanisms underlying local Ca2+ signalling differences between right and left atrial myocytes at normal and increased frequencies

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Left atrial myocytes have TAT‐associated faster Ca2+ release but are more prone to maladaptation at higher frequencies due to weaker peripheral SR Ca2+ uptake and smaller trigger Ca2+ current. Abstract Changes in heart rate affect Ca2+ signalling and contractility in ventricular muscle, but the effects on atrial Ca2+ signalling ...
