Contractile activity during physical exercise induces an increase in GLUT4 expression in skeletal muscle, helping to improve glucose transport capacity and insulin sensitivity. An important mechanism by which exercise upregulates GLUT4 is through the activation of Ca(2+)/calmodulin-dependent protein kinase II (CaMKII) in response to elevated levels of cytosolic Ca(2+) during muscle contraction....
Cells attaching to an extracellular matrix through integrins flatten out (spread) on the matrix, eliciting cellular signals needed for survival. We show that the shape of the nucleus changes and the nuclear calcium level increases in spreading cells. Moreover, cell spreading and osmotic stretching of isolated nuclei cause release of perinuclear Ca(2+), and patch clamping of nuclei reveals stret...
The pulmonary myocardium is a muscular coat surrounding the pulmonary and caval veins. Although its definitive physiological function is unknown, it may have a pathological role as the source of ectopic beats initiating atrial fibrillation. How the pulmonary myocardium gains pacemaker function is not clearly defined, although recent evidence indicates that changed transcriptional gene expressio...
