The Journal of Physiology, EarlyView.Abstract figure legend Blebbistatin reduces Ca2+ buffering in induced pluripotent stem cell‐derived atrial cardiomyocytes. Blebbistatin, a widely used excitation–contraction uncoupling agent, decreases calcium (Ca2+) buffer affinity (increased buffer dissociation constant), leading to elevated diastolic Ca2+ levels, increased sarcoplasmic reticulum Ca2+

Region-specific and activity-dependent regulation of SVZ neurogenesis and recovery after stroke. [PDF]
, 2019 Stroke is the leading cause of adult disability. Neurogenesis after stroke is associated with repair; however, the mechanisms regulating poststroke neurogenesis and its functional effect remain unclear. Here, we investigate multiple mechanistic routes of

Phosphorylation of Spinophilin Modulates Its Interaction with Actin Filaments [PDF]
, 2003 Spinophilin is a protein phosphatase 1 (PP1)- and actin-binding protein that modulates excitatory synaptic transmission and dendritic spine morphology. We report that spinophilin is phosphorylated in vitro by protein kinase A (PKA).

TMEM16A channel signalling microdomains in the regulation of vascular function
The Journal of Physiology, EarlyView.Abstract figure legend Schematic representation of TMEM16A channel signalling microdomains. Calcium influx or calcium release from the endoplasmic/sarcoplasmic reticulum (ER/SR) activates TMEM16A channels through interactions with regulatory proteins in vascular smooth muscle cells or endothelial cells. TMEM16A channel activation drives chloride efflux,

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 ...

Ca2+/Calmodulin-Dependent Protein Kinase II Activity and Expression in the Aged Mouse Hippocampus [PDF]
, 2018 CaM Kinase II (Ca2+/calmodulin-dependent protein kinase II) is a serine/threonine-specific protein kinase enzyme that acts as a critical regulator of learning and memory. It has previously been shown that the inability of CaMKII to maintain activation is

The Journal of Physiology, EarlyView.Abstract figure legend In rat and human adult ventricular myocytes, acute hyperglyceaemia (Glucose) causes increased glucose uptake (via GLUT) leading to O‐GlcNAcylation of CaMKII at Ser280, such that CaMKII activates NADPH oxidase 2 (NOX2) to increase cytosolic reactive oxygen species (ROS). That perturbs the ROS to Antioxidant (AntiOx) balance.

The Journal of Physiology, EarlyView.Abstract figure legend To investigate the role of glucose availability in fetal left ventricle (LV) development, this study assessed whether maternal late gestation undernutrition (LGUN; 50% of Control diet) induced alterations in the contractility, metabolic, and hormonal profile can be ameliorated in LGUN fetuses receiving glucose infusion (LGUN+G ...
