Abstract
ABSTRACT The zebrafish (Danio rerio) has become a popular model for human cardiac diseases and pharmacology including cardiac arrhythmias and its electrophysiological basis. Notably, the phenotype of zebrafish cardiac action potential is similar to the human cardiac action potential in that both have a long plateau phase. Also the major inward and outward current systems are qualitatively similar in zebrafish and human hearts. However, there are also significant differences in ionic current composition between human and zebrafish hearts, and the molecular basis and pharmacological properties of human and zebrafish cardiac ionic currents differ in several ways. Cardiac ionic currents may be produced by non-orthologous genes in zebrafish and humans, and paralogous gene products of some ion channels are expressed in the zebrafish heart. More research on molecular basis of cardiac ion channels, and regulation and drug sensitivity of the cardiac ionic currents are needed to enable rational use of the zebrafish heart as an electrophysiological model for the human heart.
期刊介绍：
Channels is an open access journal for all aspects of ion channel research. The journal publishes high quality papers that shed new light on ion channel and ion transporter/exchanger function, structure, biophysics, pharmacology, and regulation in health and disease.
Channels welcomes interdisciplinary approaches that address ion channel physiology in areas such as neuroscience, cardiovascular sciences, cancer research, endocrinology, and gastroenterology. Our aim is to foster communication among the ion channel and transporter communities and facilitate the advancement of the field.
