The zebrafish (Danio rerio) has been recognized as a promising animal model for studies of developmental biology and human diseases. Among the many advantages of this model in comparison to rodents are the ease of visualization of early development and relatively low maintenance cost. The zebrafish model is considered genetically useful in the investigation of human diseases, with recent successful applications of this model in epilepsy studies. However, studies using zebrafish to elucidate the mechanisms involved in epilepsy are still relatively scarce. Thus, the main objective of this project is to establish a model for zebrafish genetic epilepsies. Therefore, the strategy initially employed will be knockdown of SCN1A orthologous, which is one of the genes with greater clinical applicability among those already identified for the various epilepsy syndromes, using morpholinos (MO) antisense to block target mRNA expression in zebrafish. The new techniques that will be implemented in the laboratory will allow our group to develop an innovative research line and become more competitive internationally with regard to studies of epilepsy using zebrafish.
