Glucocorticoid Receptor-Regulated Gene Networks and Mental Health

Stressors, including those occurring in early development, predict an increased risk for psychopathology. The challenge is that of defining causal pathways that connect stressful conditions to specific health outcomes and then leveraging this knowledge toward treatments. This review focuses on glucocorticoids (GCs), the end products of stressor-induced hypothalamic-pituitary-adrenal axis activity, and reviews evidence, including recent multiomics analyses, regarding their role in mental health. We outline the challenges in translating this knowledge into effective treatments and recent evidence for the potential of gene network analyses to identify molecular pathways linking stress to psychopathology. A detailed examination of GC activity through the glucocorticoid receptor is presented as an example of the complexities involved in achieving this research objective and paths to novel interventions through gene network analyses.
