Gene Expression Analysis Identifies Cholesterol Metabolism Dysregulation in Hippocampus of Phenytoin-Resistant Pentylenetetrazol-Kindled Epileptic Mice

AbstractPharmaco-resistant Epilepsy has been a major challenge for medical interventions in controlling seizures. To date, up to 33% of the patients with epilepsy do not show adequate response to anti-epileptic drugs even after prolonged combinatorial drug usage. Using microarray, this study explores the changes in hippocampal gene expression in the phenytoin-resistant pentylenetetrazol (PTZ)-kindled mouse model of epilepsy. Our results from mRNA microarray analysis show distinct gene expression profiles in the hippocampus of phenytoin-resistant and sensitive mice. Pathway enrichment analysis showed differential expression of genes involved in cholesterol biosynthesis in phenytoin-resistant and sensitive mice.
