Abstract:
Enkephalin gene expression is modulated by the dopaminergic system in the rat striatum. Intraperitoneal administration of the typical neuroleptic drugs haloperidol (1mg/kg) and fluphenazine (3mg/kg) significantly increase levels of proenkephalin mRNA in the caudal striatum compared to saline treated controls, although the atypical neuroleptic drug clozapine (3mg/kg) has no effect on the levels of proenkephalin mRNA in the rat. Methiothepin (10mg/kg), an antipsychotic with the ability to antagonise both serotonin and dopamine receptors, can also induce proenkephalin mRNA levels in rat striatum. This induction is observed twenty-four hours after the drugs are given. Tachykinin gene expression is modulated by the dopaminergic system in the rat striatum. Intraperitoneal administration of the typical neuroleptic drugs haloperidol (1mg/kg) and fluphenazine (3mg/kg) significantly reduce the levels of preprotachykinin mRNA in the rat striatum, compared to saline treated controls. This effect is observed twenty-four hours after drug administration. The atypical neuroleptic drug clozapine (3mg/kg) and the antipsychotic methiothepin (10mg/kg) have no significant effect on the levels of preprotachykinin mRNA in the rat striatum. Somatostatin gene expression in the rat striatum is significantly increased by low doses of the atypical neuroleptic drug clozapine (3mg/kg) and by the antipsychotic drug methiothepin (10mg/kg), after acute administration. Acute treatment with typical neuroleptics has no effect in the rat striatum.
