Project description:Analysis of the dentate gyrus of amygdala electrical stimulation model of temporal lobe epilepsy. Results provide insight into the molecular mechanism underlying epileptogenesis. This study was designed to estimate changes in gene expression levels after 7 and 30 days after electrical stimulation of amygdala as a model of temporal lobe epilepsy. The advantage of this study is time matched control (sham operated animals sacrificed at the same age as stimulated animals).
Project description:Analysis of the dentate gyrus of amygdala electrical stimulation model of temporal lobe epilepsy. Results provide insight into the molecular mechanism underlying epileptogenesis. This study was designed to estimate changes in miRNA expression levels after 7, 14, 30 and 90 days after electrical stimulation of amygdala as a model of temporal lobe epilepsy. The advantage of this study is time matched control (sham operated animals sacrificed at the same age as stimulated animals).
Project description:In vivo high frequency stimulated of left dentate gyrus was performed on anaesthetised rats followed by RNA-seq to study long-term potentiation. Both left and right dentate gyrus was collected, sequenced and compared against each other for naive rats and for rats 30 min, 2 hours, and 5 hours post-HFS.
Project description:The aim of this study was to investigate whether the differences in memory decline associated with aging are a result of differences in gene expression. We first categorized age-unimpaired and age-impaired rats based on their performance in the Morris water maze, when compared to young rats. Then we isolated messenger RNA from the dentate gyrus of the hippocampus of each animal to interrogate Affymetrix RAE 230A rat genome microarrays. Supervised statistical analysis of the different groups of aged animals recognized 85 genes (p<0.005) that were significantly different in the dentate gyrus of aged rats that had learned the Morris water maze (MWM) paradigm when compared to learning impaired and a number of controls for stress, exercise and non-spatial learning. In addition, statistical analysis of the microarray data that included young and aged rats identified 1129 genes (p<0.005) that were differentially expressed between aged and young rats independent of behavior, but due to aging alone. Keywords: behavior comparison, age comparison
Project description:The dentate gyrus of the hippocampus is a brain region involved in learning, memory formation, and spatial coding. We performed single-cell RNA-sequencing of the dentate gyrus of young and old mice to identify the age-induced changes.
Project description:The gene expression patterns in the dentate gyrus of wild-type mice during postnatal development were examined using Affymetrix GeneChip arrays.
