Sommario Le tecniche di sequenziamento nuova generazione hanno rivoluzionato l’identificazione dei geni-malattia, accelerando la scoperta nuove mutazioni e nuovi geni candidati per le malattie della tiroide. Per far fronte a questo flusso informazioni genetiche è importante disporre modelli animali adeguati studiare i meccanismi che regolano lo sviluppo tiroide, biodisponibilità l’azione degli ...

Much of our current understanding of the function of genes modulating the normal process of embryonic development has come from mutant analysis. The availability of thousands of mutant lines in zebrafish that allows for identification of novel genes regulating various aspects of embryogenesis has been instrumental in establishing zebrafish as a robust and reliable genetic system. With the advan...

Unlike mammals, zebrafish can regenerate their injured spinal cord and regain control of caudal tissues. It was recently shown that Wnt/β-catenin signaling is necessary for spinal cord regeneration in the larval zebrafish. However, the molecular mechanisms of regeneration may or may not be conserved between larval and adult zebrafish. To test this, we assessed the role of Wnt/β-catenin signalin...

The zebrafish is an ideal model organism for behavioral genetics and neuroscience. The high conservation of genes and neurotransmitter pathways between zebrafish and other vertebrates permits the translation of research between species. Zebrafish behavior can be studied at both larval and adult stages and recent research has begun to establish zebrafish models for human disease. Fast scan cycli...

Among a diversity of animal models of disease, the zebrafish is a promising model organism for enabling novel translational biomedical research. To fully achieve the latter, a key requirement is to match molecular readouts measured in zebrafish with information relevant to health and disease in humans. A fundamental step in this direction is to accurately map gene sequences from zebrafish to hu...

The zebrafish has become an important genetic model, but their small size makes them impractical for traditional physiological studies. In contrast, the closely related giant danio is larger and can be utilized for physiological studies that can also make use of the extensive zebrafish genomic resources. In addition, the giant danio and zebrafish appear to exhibit different growth types, indica...

Stress is the body’s reaction to any change that requires adaptive responses. In various organisms, stress a seizure-related comorbidity. Despite exposure stressors eliciting aversive behaviors in zebrafish, there are no data showing whether potentiates epileptic seizures this species. Here, we investigated previous an intense acute stressor positively modulates susceptibility pentylenetetrazol...

Progranulin (PGRN) is a secreted glycoprotein with multiple biological functions in early embryogenesis, anti-inflammation, and neurodegeneration. A good model for the functional study of PGRN zebrafish knockdown or knockout grn, gene encoding PGRN. Morpholino oligonucleotides (MOs) zinc finger nucleases have been used to generate grn models, yet they shown inconsistent phenotypes due either ne...

Zebrafish (Danio rerio) are becoming one of the most important model organisms in behavioural neuroscience. It has been shown repeatedly that different zebrafish strains show large differences. These divergent profiles may have a genetic basis, but environmental factors and previous experience also known to greatly affect phenotype zebrafish. could be expected differences at larval stage should...

The zebrafish (Danio rerio) is a useful vertebrate model for use in cardiovascular drug discovery. The present study aimed to construct optimized methods for the study of intravascular lipid metabolism of zebrafish. The lipophilic dye, Oil Red O, was used to stain fasting zebrafish one to eight days post-fertilization (dpf) and to stain 7-dpf zebrafish incubated in a breeding system containing ...
