Abstract
Despite the extensive knowledge about the effects of acute restraint stress (ARS) in rodents, zebrafish research is still elementary in this field, and the consequences of stress on purinergic system are unclear. Therefore, we evaluated the effects of ARS on behavior, biochemical, and molecular parameters in zebrafish brain. Animals were submitted to a 90 min ARS protocol and tested for anxiety levels, exploratory behavior, and memory performance. Furthermore, we analyzed ectonucleotidase and adenosine deaminase activities and their gene expression profile, as well as transcription of adenosine receptors. ARS increased anxiety, but did not impair locomotion or cognition. ARS significantly increased ATP hydrolysis, decreased cytosolic ADA activity, and changed the entpd and adora gene expression. In conclusion, ARS disturbed zebrafish behavior, and we hypothesize that the augmentation in adenosine-mediated signaling may be a strategy to reestablish homeostasis and normal behavior after a stressful event.
