Area of Science:

  • Genomics
  • Neuroscience
  • Molecular Biology

Background:

  • Microarray technology enables simultaneous measurement of thousands of mRNA levels, a technique known as gene expression profiling.
  • Gene expression profiling is a powerful tool for discovering novel genes implicated in psychiatric disorders, particularly when applied to animal models or post-mortem tissues.
  • This genomic approach complements traditional methods like positional cloning for gene discovery.

Purpose of the Study:

  • To review the application of microarray technologies and gene expression profiling in animal models and post-mortem tissues of bipolar disorder.
  • To describe a novel approach, convergent functional genomics, for rapid identification of candidate disease genes.
  • To highlight the integration of gene profiling and positional cloning for enhanced gene discovery in psychiatric disorders.
