Microarray gene expression profiling of mouse brain mRNA in a model of lithium treatment

Abstract

These genes are involved in a diverse range of biological functions, including maintaining metal ion homeostasis and chemical/electrical gradients across membranes, regulating RNA polymerase II, protein degradation, and G-protein-coupled signal transduction. These results indicate that lithium can regulate a large number of different cellular pathways in the brain. Understanding the molecular and cellular mechanisms by which lithium achieves its therapeutic action represents a valuable step in clarifying the pathophysiology of bipolar disorder.
