1 Effects of antipsychotic drugs on neurotoxicity, expression of fos-like protein and c-fos mRNA in the retrosplenial cortex after administration of dizocilpine. Dizocilpine Maleate Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus
2 In this study, we examined the effect of clozapine, olanzapine, risperidone and haloperidol on the neuropathology (i.e. neuronal vacuolization) and the expression of Fos-like protein and c-fos mRNA in the retrosplenial cortex of female Sprague-Dawley rats induced by the NMDA receptor antagonist dizocilpine. Dizocilpine Maleate Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus
3 Furthermore, pretreatment (15 min) with clozapine or olanzapine, but not risperidone or haloperidol, significantly attenuated the expression of Fos-like protein in the retrosplenial cortex induced by dizocilpine (0.5 mg/kg, s.c.) in a dose-dependent manner. Dizocilpine Maleate Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus
4 The marked expression of c-fos mRNA in the rat retrosplenial cortex induced by the administration of dizocilpine (0.5 mg/kg, s.c.) was significantly attenuated by pretreatment (15 min) with clozapine (10 mg/kg) or olanzapine (10 mg/kg), but not risperidone (10 mg/kg) or haloperidol (10 mg/kg). Dizocilpine Maleate Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus
5 The present results suggest that pharmacologically relevant doses of clozapine or olanzapine, but not risperidone or haloperidol, block the neuropathological changes and the expression of Fos-like protein and c-fos mRNA in the rat retrosplenial cortex elicited by the administration of dizocilpine. Dizocilpine Maleate Fos proto-oncogene, AP-1 transcription factor subunit Rattus norvegicus
