About this Research Topic
Animal heart models of human heart diseases are cornerstones of drug discovery, both to identify new drug targets and to screen new drugs for cardiovascular toxicities. In less than four decades since Streisinger et al. advocated the use of zebrafish as a laboratory animal in 1981, the two-chamber zebrafish heart has rapidly emerged as popular, high-throughput vertebrate model to study human cardiac electrophysiology and myopathies. There are so many reasons for the well-deserved popularity of this unique animal model: high fecundity, rapid development, high genetic homology with mammals (particularly humans), ease of genetic manipulation, transparency of the embryos, extraordinary capability to regenerate the injured heart retained throughout adulthood, and superior similarity to human electrophysiological phenotype (particularly when compared with the mouse heart model). On the other hand, our understanding of zebrafish cardiac electrophysiology is limited, especially in comparison to the discovery pace in zebrafish developmental biology. Translational applications in cardiovascular medicine could be further advanced with more in-depth insights into the electrophysiology of the zebrafish heart, particularly the adult heart. Therefore, the aim of this Frontiers Research Topic is to provide a platform to promote and disseminate the latest ideas and insights in zebrafish cardiac arrhythmogenesis and cardiomyopathies.
