    There is accumulating evidence that disturbances in N-methyl-D-aspartate receptor (NMDA-R) functioning are associated with the pathogenesis of schizophrenia. To assess actual changes in the expression of the GluN1 subunit and its isoforms, we measured absolute differences in the levels of mRNA/protein for panGluN1 (eight isoforms altogether) as well as the mRNA individual isoforms in the postmortem left/right hippocampus of patients with schizophrenia in comparison with non-psychiatric subjects. Our results suggest that NMDA-R hypofunction in schizophrenia might be selectively dependent on the dysregulation of GluN1 subunit expression, which exhibits a somewhat different expression in the left/right hippocampus of psychotic patients.
