Abstract:
:The non-competitive N-methyl-D-aspartate (NMDA) receptor antagonist such as an abused drug phencyclidine (PCP) causes the induction of heat shock protein HSP-70, a sensitive marker of neuronal injury, in the retrosplenial cortex of rat brain. The present study was undertaken to examine the role of a -amino-3- hydroxy-5-methyl-4-isoxazole propionate (AMPA) receptor in the expression of heat shock protein HSP-70 and hsp-70 mRNA in the retrosplenial cortex by PCP. Administration of PCP (50 mg/kg, i.p.) caused the induction of heat shock protein HSP-70 in the retrosplenial cortex of rat brain, whereas no HSP-70 immunoreactivity was detected in the vehicle-treated group. Pretreatment with a potent and selective AMPA receptor antagonist YM90K (1, 3 or 10 mg/kg, i.p; 15 min) inhibited in a dose dependent manner, the induction of heat shock protein HSP-70 by PCP (50 mg/kg). Furthermore, administration of PCP (50 mg/kg, i.p) caused marked expression of hsp-70 mRNA in the retrosplenial cortex of rat brain, whereas the expression of hsp-70 mRNA was NOT found in the vehicle-treated group. Pretreatment with YM90K (1, 3 or 10 mg/kg, i p; 15 min) also inhibited the expression of hsp-70 mRNA by PCP (50 mg/kg), in a dose-dependent manner. These results suggest that AMPA receptor may play a role in the expression of heat shock protein HSP-70 and heat shock gene hsp-70 mRNA in the retrosplenial cortex of rat brain by non-competitive NMDA receptor antagonists such as PCP.
