Abstract
Agedependent changes of gene expression in the prefrontal cortex PFC of rats around the time of puberty were investigated by means of microarray and quantitative polymerase chain reaction qPCR About 127 and 138 genes were increased and decreased respectively in the PFC of rats at postpuberty PD56 compared with those at prepuberty PD35 Functional analysis showed significant associations of these genes with aging cellular development and neuropsychological disorders qPCR analysis confirmed downregulation of seven genes related to myelination As these genes have been reported to be diminished in the brain of patients with schizophrenia the results of this study suggest an exaggerated maturation process may contribute to the pathogenesis of psychotic disorders
