title: [Roles of glutamate receptor in c-fos gene expression and epilepsy susceptibility in rats].
abstract: We use NMDA to induce expression of c-fos mRNA as a marker to observe the activity of NMDA receptor in neurons during development, and compare the activity of NMDA receptor between audiogenic epilepsy -prone (P77PMC) and audiogenic epilepsy resistant rats brain. In primary culture of rats cerebral cortical neurons NMDA induced c-fos mRNA expression exhibits dose and time-dependent changes, which can be prevented by antagonists. During the development of neurons, the NMDA -induced c-fos mRNA expression reaches a maximum at day 24. NMDA-induced c-fos mRNA expression of P77PMC rats is higher than that of controls during 6 to 24 days in vitro with significant difference (P < 0.05) at day 18. To present changes in c-fos mRNA expression induced by NMDA in cultured P77PMC rat cortical neurons may be one of the factors related to susceptibility of epilepsy in P77PMC rats.
