Abstract
While microarray studies are generating novel insights into the etiology of major psychiatric disorders, the validation of microarray-identified candidate genes and their role in the causality of these disorders has been less often studied. We have previously demonstrated, by microarray, up-regulation of SELENBP1 in the brain and blood of patients with schizophrenia. The main aim of the current study was to validate this finding using quantitative real-time PCR (QPCR) in an independent brain cohort that included patients with bipolar disorder. Our sample consisted of mRNAs from the dorsolateral prefrontal cortex (dlPFC) of 34 schizophrenic patients, 33 bipolar disorder patients (including 20..
