Reduced dorsal and orbital prefrontal gray matter volumes in schizophrenia.
BACKGROUND Converging neuroanatomic, neurophysiological, and neurobehavioral evidence implicate prefrontal subregions in schizophrenia. Neuroanatomic studies with magnetic resonance (MR) imaging enable regional volume parcellation. Inconsistent reports may relate to variable methods and small samples. We attempted to resolve volume differences within sectors of the prefrontal lobe in a large sa...
متن کاملDysbindin-1 in dorsolateral prefrontal cortex of schizophrenia cases is reduced in an isoform-specific manner unrelated to dysbindin-1 mRNA expression.
DTNBP1 (dystrobrevin binding protein 1) remains a top candidate gene in schizophrenia. Reduced expression of this gene and of its encoded protein, dysbindin-1, have been reported in the brains of schizophrenia cases. It has not been established, however, if the protein reductions encompass all dysbindin-1 isoforms or if they are associated with decreased DTNBP1 gene expression. Using a matched ...
متن کاملHuman dysbindin (DTNBP1) gene expression in normal brain and in schizophrenic prefrontal cortex and midbrain.
CONTEXT The schizophrenia-susceptibility gene dysbindin (DTNBP1 on 6p22.3) encodes a neuronal protein that binds to beta-dystrobrevin and may be part of the dystrophin protein complex. Little is known about dysbindin expression in normal or schizophrenic brain. OBJECTIVES To determine whether brain regions implicated in schizophrenia express dysbindin and whether abnormal levels of dysbindin ...
متن کاملDysbindin-1 is reduced in intrinsic, glutamatergic terminals of the hippocampal formation in schizophrenia.
Eleven studies now report significant associations between schizophrenia and certain haplotypes of single-nucleotide polymorphisms in the gene encoding dysbindin-1 at 6p22.3. Dysbindin-1 is best known as dystrobrevin-binding protein 1 (DTNBP1) and may thus be associated with the dystrophin glycoprotein complex found at certain postsynaptic sites in the brain. Contrary to expectations, however, ...
متن کاملBrain volumes in psychotic youth with schizophrenia and mood disorders.
BACKGROUND We sought to test the hypothesis that deficits in grey matter volume are characteristic of psychotic youth with early-onset schizophrenia-spectrum disorders (EOSS) but not of psychotic youth with early-onset mood disorders (EOMD). METHODS We used magnetic resonance imaging to examine brain volume in 24 psychotic youth (13 male, 11 female) with EOSS (n = 12) or EOMD (n = 12) and 17 ...
