Abstract
BACKGROUND
The POU-domain transcription factor Oct-6 has been reported to be differentially expressed between schizophrenic and control post-mortem brains. In this study, we attempted to replicate this finding and to discover whether Oct-6 was also dysregulated in bipolar disorder and major depression.
METHODS
Oct-6 mRNA and protein expression were determined by in-situ hybridization and immunohistochemistry respectively in sections of post-mortem brain.
RESULTS
We did not observe any differences in Oct-6 expression between any of the groups under study. Oct-6 mRNA and protein was identically expressed in the hippocampal and cortical regions of most specimens in all groups, including controls.
CONCLUSION
Oct-6 is, therefore, unlikely to be a specific marker for any psychological disorder; rather its expression in controls suggests that it is normally expressed in most adult brains.
