Abstract
Steroid hormones coordinate the activity of many brain regions by binding to nuclear receptors that act as transcription factors. This study uses genome-wide correlation of gene expression in the mouse brain to discover (i) brain regions that respond in a similar manner to particular steroids, (ii) signaling pathways that are used in a steroid receptor and brain region-specific manner, and (iii) potential target genes and relationships between groups of target genes. The data constitute a rich repository for the research community to support further new insights in neuroendocrine relationships and to develop novel ways to manipulate brain activity in research or clinical settings.
