1 To study the seizure-induced activation of glutamate decarboxylase, we investigated the expression of both embryonic and adult glutamate decarboxylase messenger RNAs in the adult rat hippocampus after kainic acid administration by semi-quantitative reverse transcription-coupled polymerase chain reaction, in situ hybridization and immunoblotting. Kainic Acid glutamate-ammonia ligase Rattus norvegicus
2 The expression of embryonic glutamate decarboxylase transcripts, identified here as the splice variant that contains exon 7/B, peaked at about 2h after kainic acid injection and gradually returned to nearly basal levels by 24h. Kainic Acid glutamate-ammonia ligase Rattus norvegicus
3 Expression of the messenger RNA encoding for an alternatively spliced, truncated form of the GABA-synthesizing enzyme glutamate decarboxylase was detected in dentate granule cells briefly after kainic acid-induced seizures. Kainic Acid glutamate-ammonia ligase Rattus norvegicus
