Statistical analyses were performed by Mann-Whitney test with p<0.05. Results: The mean±SEM obtained were: (i) cox2a: SG+indo 0.5±0.06 vs SG 1.3±0.12 (p=0.004); (ii) cox2b: SG+indo 0.73±0.06 vs SG 1.73±0.18 (p=0.004). Animals pretreated with indomethacin showed longer latency to reach seizure: SG+indo: 4.6±0.33 vs SG: 2.92±0.17 (p=0.0004) and presented less number of seizure-like behavior response when compared to SG (SG+indo: 11.2±1.5 vs SG: 38.16±4.5; p=0.003). Animal Ethical Committee/UNICAMP (#3098-1). Conclusion: Indomethacin treatment prior to PTZ-induced seizure reduced the cox2a and cox2b mRNA expression levels in zebrafish brain, increased the latency to seizure onset and significantly decreased the number of seizures during PTZ exposure. Our findings support evidence that zebrafish is a valuable model for further investigations of the main role of inflammation in seizure as well as a valuable model for anti-inflammatory screening of compounds that are potentially therapeutic for seizures.
