title: Molecular biology and the major psychoses.
abstract: OBJECTIVE
  To highlight the potential role of molecular biological studies in examining the expression of genes of interest in brain tissue to elucidate the pathophysiological basis of the major psychoses.
  
  
  METHODS
  To review the principles underlying the available techniques for expression studies.
  
  
  RESULTS
  Detection of messenger RNA by in situ hybridisation and quantitation by Northern analysis are powerful tools to detect abnormalities in gene expression in brain tissue.
  
  
  CONCLUSIONS
  The availability of simple techniques to examine the expression of RNA and protein products of individual genes, including examination at the level of individual cells, offers a clear opportunity to define the molecular basis of the major psychoses.
