Dephospho-dynamin 1 coupled to activity-dependent bulk endocytosis participates in epileptic seizure in primary hippocampal neurons.

Background And Purpose: Epilepsy is a severe neurological and mental disorder, and not all patients adequately respond to the current treatments. Dynamin 1 plays a key role in synaptic endocytosis and the modulation of neurological function.

Material And Methods: Cultured hippocampal neurons were used in the study.

Association of RASgrf1 methylation with epileptic seizures.

DNA methylation, one of the mechanisms of epigenetic regulation, has been suggested to be related with epilepsy. RASgrf1 is a paternally imprinted gene and has a differentially methylated region (DMR) at the promoter that can silence gene expression. We have previously observed the down-regulation of RASgrf1 in the temporal neocortex of epilepsy patients and in the hippocampus of epileptic animals.
