Project description:NRSF mediated epigenetic mechanisms of ion channel dysfunction in experimental temporal lobe epilepsy
Project description:Ion channel splice array data collected from temporal neocortex brain tissue collected from patients with mesial temporal lobe epilepsy. Temporal cortex samples from control subjects were compared to temporal neocortex of patients with mesial temporal lobe epilepsy
Project description:Ion channel splice array data from temporal cortex brain tissue samples collected from control subjects (no mesial temporal lobe epilepsy). Keywords: disease associated splicing changes Temporal cortex samples from control subjects were compared to temporal neocortex of patients with mesial temporal lobe epilepsy
Project description:Transcriptome studies of brain resections from mesial temporal lobe epilepsy (mTLE) patients revealed a dysregulation of transforming growth factor (TGF)-β, interferon (IFN)-α/β and nuclear factor erythroid 2-related factor 2 (NRF2) pathways among other neuroinflammatory mechanisms. Since ubiquitin-specific proteases (USP), in particular USP15, have been shown to regulate these pathways, we hypothesized that the blockade of USP15 may provide therapeutic relief in treatment-resistant epilepsies. The intrahippocampal kainate mouse model for mTLE, an established model for pharmacoresistant epilepsy was used for validation of USP15 as a therapeutic target. Transgenic mice which inducibly lack USP15 underwent intrahippocampal kainate injections to investigate the impact of USP15 downregulation at the transcriptomic level.

The intrahippocampal kainate mouse model for mTLE, an established model for pharmacoresistant epilepsy was used for validation of USP15 as a therapeutic target. Transgenic mice which constitutively lack USP15 underwent intrahippocampal kainate injections to investigate the impact of USP15 inactivation at the transcriptomic level.
Project description:It has long been established that in neurological disease models, KA is a potent excitotoxin, mediating acute limbic seizures and long-term morphologic changes in the hippocampus, which are hallmark characteristics seen in temporal lobe epilepsy (i.e. mossy-fiber sprouting, neuronal loss, and reactive gliosis; Ben-Ari and Cossart, 2000). Persuasive clinical evidence employing KA receptor agonists further substantiate the detrimental effects of kainate. For instance, domoic acid (a structural analogue of kainate) has been found to inflict detrimental damage the hippocampus through a real-life outbreak incident of toxic encephalopathy caused by ingestion of mussels contaminated with domoic acid (Pearl et al., 1990).
