- Nemopilema nomurai venom (NnV) is severely toxic to many organisms. However, the mechanism of its poisoning has not been properly understood yet. The present work demonstrates that zebrafish (Danio rerio) is an alternative vertebrate model for studying NnV jellyfish venom for the first time. In this model, NnV appears to cause severe hemorrhage and inflammation in cardiopulmonary regions of zebrafish. NnV also altered the swimming behavior of zebrafish accompanied by a significant downregulation of acetylcholinesterase (AChE) activity in brain tissues. Histopathological changes observed for various organs of D. rerio caused by NnV corresponded to an increase in lactate dehydrogenase (LDH) activity in tissues. NnV also significantly altered glutathione S-transferase (GST) activity in cardiopulmonary and brain tissues of D. rerio. SDS-PAGE revealed many protein bands of NnV of various sizes after silver staining. Taken together, these results indicate that Danio rerio can be a useful alternative animal model for jellyfish venom toxicology studies. Findings of the present study also suggest that Danio rerio could be used to develop an effective treatment strategy and discover the mechanism of action of jellyfish venom envenomation.
