Project description:Using microarray analyses and subsequent verification by RT-PCR, we studied the changes in gene expression in the inferior colliculus after an ictal event in one models of audiogenic epilepsy, genetic audiogenic seizure hamster (GASH:Sal). GASH:Sal, a hamster strain developed at the University of Salamanca, exhibits genetic audiogenic epilepsy similar to human Grand Mal epilepsy. GASH:Sal shows an autosomal recessive inheritance for susceptibility to audiogenic seizures, which manifest more severely in young animals; the seizure severity progressively declines with age. Genetic animal models of epilepsy are an important tool for further understanding the basic cellular mechanisms underlying epileptogenesis and for developing novel antiepileptic drugs. We conducted a comparative study of gene expression in the inferior colliculus, a nucleus that triggers audiogenic seizures, using two animal models, the Wistar audiogenic rat (WAR) and the genetic audiogenic seizure hamster (GASH:Sal). For this purpose, both models were subjected to auditory stimulation, and 60 minutes after stimulation, the inferior colliculi were collected. As a control, intact Wistar rats and Syrian hamsters were subjected to identical stimulation and tissue preparation protocols to those performed on the experimental animals. A total of 24 animals were used in this study according to the following distribution: 12 control Syrian hamsters (Mesocricetus auratus) and 12 GASH:Sal at 16 weeks of age and a body weight of approximately 60 g. Six animals Syrian and GASH:Sal hamsters, respectively, were exposed to auditory stimulation, and 60 min after the seizures, we harvested the IC for all gene expression analyses (stimulated Syrian hamsters and stimulated GASH:Sal hamsters). As controls, other six animals Syrian and GASH:Sal hamsters, respectively, were not exposed to the same stimulation (Syrian hamsters and GASH:Sal hamsters).

Project description:Using microarray analyses and subsequent verification by RT-PCR, we studied the changes in gene expression in the inferior colliculus after an ictal event in one models of audiogenic epilepsy, Wistar audigenic rat (WAR). WAR is a genetically selected strain susceptible to audiogenic seizures that was inbred in the School of Medicine of Ribeirão Preto (Brazil) beginning in 1990. This strain is a model of audiogenic idiopathic epilepsy that develops tonic-clonic generalized seizures. Genetic animal models of epilepsy are an important tool for further understanding the basic cellular mechanisms underlying epileptogenesis and for developing novel antiepileptic drugs. We conducted a comparative study of gene expression in the inferior colliculus, a nucleus that triggers audiogenic seizures, using two animal models, the Wistar audiogenic rat (WAR) and the genetic audiogenic seizure hamster (GASH:Sal). For this purpose, both models were subjected to auditory stimulation, and 60 minutes after stimulation, the inferior colliculi were collected. As a control, intact Wistar rats and Syrian hamsters were subjected to identical stimulation and tissue preparation protocols to those performed on the experimental animals. A total of 15 animals were used in this study according to the following distribution: 9 male WAR and 6 male control rats (Rattus norvegicus, Wistar albino, Charles River Laboratories) at 12 weeks of age and a body weight of approximately 230 g. The animals were exposed to auditory stimulation, and 60 min after the seizures, we harvested the IC for all gene expression analyses. As controls, normal Wistar rats were exposed to the same stimulation according to the identical procedure. For gene microarray (Rat Gene 1.0 ST), the rats were randomly divided into two groups, and we used both sides of the IC (ipsilateral and contralateral) from each animal: stimulated Wistar rats and stimulated WAR rats.

Project description:The GASH/Sal hamster (Genetic audiogenic seizure, Salamanca) is a model of audiogenic seizures with the epileptogenic focus localized in the inferior colliculus (IC). The sound-induced seizures exhibit a short latency (7-9 seconds), which implies innate protein disturbances in the IC as a basis for seizure susceptibility and generation. Here, we aim to study the protein profile in the GASH/Sal IC in comparison to controls. Protein samples from the IC were processed for enzymatic digestion and then analyzed by mass spectrometry in Data-Independent Acquisition mode. After identifying the proteins using the UniProt database, we selected those with differential expression. We identified 5254 proteins, of which 184 were differentially expressed, 126 upregulated and 58 downregulated. Moreover, a small number of proteins were uniquely found in the GASH/Sal or the control. The resuls indicated a protein profile alteration in the epileptogenic nucleus that might underlie the innate occuring audiogenic seizures in the GASH/Sal model.
