To clarify the molecular mechanism of phencyclidine (PCP)-induced schizophreniform psychosis in humans and of behavioral abnormalities in experimental animals, we used differential screening of a cDNA library from the cerebral cortex of rats treated with PCP. We identified a PCP-induced cDNA clone as the gene encoding glutamate dehydrogenase (GDH), an enzyme central to glutamate metabolism. GDH mRNA levels significantly increased as early as 15 min following PCP administration in both the cerebral cortex and the cerebellum. This effect was observed even in the presence of a protein synthesis inhibitor, cycloheximide. In contrast to a transient increase in c-fos expression, the elevation of GDH mRNA levels lasted up to 8 days after a single PCP injection. These results suggest that GDH mRNA induction may be involved in the pathology of PCP-induced psychosis, and that GDH may be one of the candidate genes that are vulnerable in subjects with schizophrenia.
