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

The 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 ...

14‐3‐3 proteins: Regulators of cardiac excitation–contraction coupling and stress responses

The Journal of Physiology, EarlyView.
Abstract figure legend 14‐3‐3 protein interactions in cardiac regulation. Schematic representation of 14‐3‐3 binding partners in excitation–contraction coupling, transcriptional regulation/development and stress response pathways. Asterisks indicate targets where the exact 14‐3‐3 binding site is unknown.

Deciphering pro‐arrhythmogenic mechanisms of EPAC in human atrial cardiomyocytes

The Journal of Physiology, EarlyView.
Abstract figure legend This study aimed to investigate the effect of exchange proteins directly activated by cAMP (EPAC) on the regulation of human atrial cardiomyocyte electrophysiology and their potential involvement in the onset of atrial fibrillation (AF).

Computational modelling of cardiac fibroblast signalling reveals a key role for Ca2+ in driving atrial fibrillation‐associated fibrosis

The Journal of Physiology, EarlyView.
Abstract figure legend A pre‐existing fibroblast signalling model was enhanced by integrating atrial‐specific components and reactions linked to atrial fibrosis and atrial fibrillation (AF). The analysis highlights the central role of Ca2⁺ signalling in driving profibrotic responses to AF‐relevant stimuli, angiotensin‐II and transforming growth factor ...

Amyloid β alters vascular CaV1.2 channel spatiotemporal properties

The Journal of Physiology, EarlyView.
Abstract figure legend Amyloid‐β1‐42 (Aβ1‐42) triggers a male‐specific signalling cascade influencing CaV1.2 spatiotemporal properties in cerebral vascular smooth muscle. The signalling pathway involves NADPH oxidase (NOX)‐derived reactive oxygen species (ROS) activation of protein kinase C (PKC). Aβ1‐42 can also activate protein kinase A (PKA).

Potential health benefits of cold‐water immersion: the central role of PGC‐1α

The Journal of Physiology, EarlyView.
Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

Small‐conductance Ca2⁺‐activated K⁺ channels in cardiac excitation–contraction coupling: Bridging mitochondria, sarcolemma and antiarrhythmic therapy

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance
