Abstract

Ca2+ is a key second messenger in the intricate workings of the heart. In cardiac myocytes, Ca2+ signaling controls or modulates electrophysiological function, excitation-contraction coupling, contractile function, energy balance, cell death, and gene transcription. Thus, diverse Ca2+-dependent regulatory processes occur simultaneously within a cell. Yet, distinct signals can be resolved by local Ca2+ sensitive protein complexes and differential Ca2+ signal integration. In addition to its importance to normal cardiac function, such regulation is also crucial in disease conditions. Ca2+ is likely involved in ectopic cardiac rhythms in both atrial and ventricular tissues through generating triggered activity often appearing as delayed afterdepolarisations, particularly following cellular Ca overloading. Recent studies also implicate Ca2+ in Na+ channel expression and properties with consequences for conduction velocity and therefore arrhythmic substrate. At the cellular level, such regulation involves control of the activity of membrane ion channels and Ca2+ handling proteins. These in turn involve multiple extra- and intracellular signaling pathways. This e-book assembles review and original articles from experts in this field. It summarises major recent progress bearing on roles of Ca2+ in cardiac electrophysiological function encompassing both normal and abnormal cardiac function. These extend from physiological roles of Ca2+ signaling in pacemaker function, in particular generation of sino-atrial pacemaker potentials, to pathological roles of abnormal Ca2+ signaling in both atrial and ventricular arrhythmogenesis. It also seeks to bridge the gap between advances in basic science and development of new therapies.

Abstract

The endometrium has been the subject of intense research in a variety of clinical settings, because of its importance in the reproductive process and its role in women’s health. In the past 15 years, significant efforts have been invested in defining the molecular phenotype of the receptive phase endometrium as well as of various endometrial pathologies. Although this has generated a wealth of information on the molecular landscape of human endometrium, there is a need to complement this information in light of the novel methodologies and innovative technical approaches. The focus of this International Journal of Molecular Sciences Special Issue is on molecular and cellular mechanisms of endometrium and endometrium-related disorders. The progress made in the molecular actions of steroids, in the metabolism of steroids and intracrinology, in endometrial intracellular pathways, in stem cells biology, as well as in the molecular alterations underlying endometrium-related pathologies has been the focus of the reviews and papers included.
