Expression of beta-arrestins and beta-adrenergic receptor kinases in the failing human heart. [PDF]

Circulation Research, 1994
The beta-adrenergic receptor system of the failing human heart is markedly desensitized. We have recently postulated that this desensitization may in part be caused by an increase in beta-adrenergic receptor kinase (beta ARK) expression. beta ARK is thought to effect desensitization by acting in concert with an inhibitor protein, called beta-arrestin ...

Semaglutide normalizes increased cardiomyocyte calcium transients in a rat model of high fat diet‐induced obesity

ESC Heart Failure, Volume 12, Issue 2, Page 1386-1397, April 2025.
Sequeira et al. reveal how the glucagon‐like peptide‐1 receptor agonist (GLP‐1‐RA) semaglutide restores cardiomyocyte function in rats subjected to a high‐fat/high‐fructose diet (HFD). Employing fluorescence‐ and patch‐clamp technology in isolated cardiac myocytes, they demonstrate that semaglutide reverses HFD‐induced activation of L‐type calcium ...

Cilostazol in patients with heart failure and preserved ejection fraction—The CLIP‐HFpEF trial

ESC Heart Failure, Volume 12, Issue 2, Page 1437-1446, April 2025.
• Cilostazol is an oral PDE‐3 inhibitor that may have advantageous effects in heart failure with preserved ejection fraction (HFpEF). • Cilostazol significantly improved short‐term heart failure‐related health status scores (KCCQ‐12) and NT‐proBNP levels when compared to placebo.

Status epilepticus: Updates on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Status epilepticus (SE) consists of prolonged, self‐sustaining seizures and is a common neurological emergency that causes respiratory compromise and neuronal injury. Without prompt treatment, the seizures can become resistant to benzodiazepines, leading to the progressive evolution of established, refractory, and super‐refractory SE.

Schisantherin A: Remodeling Gut Microbiota to Activate the Gut–Immune–Neural–Adipose Axis for Thermogenesis

iNew Medicine, EarlyView.
ABSTRACT The global obesity epidemic necessitates safe and effective strategies to enhance energy expenditure. Schisantherin A (Sin A), a lignan derived from Schisandra chinensis, has demonstrated metabolic benefits, yet its systemic mechanism remains unclear.

Biomarkers for the estimation of isoproterenol‐induced myocardial infarction: A review of key parameters

Journal of Intelligent Medicine, EarlyView.
Abstract The isoproterenol‐induced myocardial infarction model is a well‐established experimental approach for studying cardiac injury and testing potential protective treatments. By overstimulating beta‐adrenergic receptors, this model closely reproduces key features of human heart attacks, including oxidative damage, calcium imbalance, inflammatory ...

Circadian Immunity and Vascular Inflammation in Cardiovascular Disease Chronotherapy Windows: Time for a Re‐Assessment

Med Research, EarlyView.
ABSTRACT Circadian rhythms orchestrate cardiovascular physiology by regulating immune and inflammatory pathways. Disruption of these rhythms profoundly alters vascular homeostasis, thereby promoting the onset and progression of cardiovascular diseases (CVD).

Overexpression of a Neuronal Type Adenylyl Cyclase (Type 8) in Sinoatrial Node Markedly Impacts Heart Rate and Rhythm

Frontiers in Neuroscience, 2019
Heart rate (HR) and HR variability (HRV), predictors of over-all organism health, are widely believed to be driven by autonomic input to the sinoatrial node (SAN), with sympathetic input increasing HR and reducing HRV. However, variability in spontaneous

Light‐Based Molecular Tools to Precisely Monitor and Operate β‐Adrenoceptors

Medicinal Research Reviews, EarlyView.
ABSTRACT β‐Adrenoceptors are important G protein–coupled receptors involved in cardiovascular, metabolic, and neurological regulation. To study their function with high precision, light‐based molecular tools have been developed offering precise spatiotemporal control.
