Abstract

Inflammation plays a crucial role in cardiac regeneration. Numerous advantages, including a robust regenerative ability, make the zebrafish a popular model to study cardiovascular diseases. The zebrafish breakdance (bre) mutant shares several key features with human long QT syndrome that predisposes to ventricular arrhythmias and sudden death. However, how inflammatory response and tissue regeneration following cardiac damage occur in bre mutant is unknown. Here, we have found that inflammatory response related genes were markedly expressed in the injured heart and excessive leukocyte accumulation occurred in the injured area of the bre mutant zebrafish. Furthermore, bre mutant zebrafish exhibited aberrant apoptosis and impaired heart regenerative ability after ventricular cryoinjury. Mild dosages of anti-inflammatory or prokinetic drugs protected regenerative cells from undergoing aberrant apoptosis and promoted heart regeneration in bre mutant zebrafish. We propose that immune or prokinetic therapy could be a potential therapeutic regimen for patients with genetic long QT syndrome who suffers from myocardial infarction.
