Transcription factor activity profiling reveals the role of REST and LEF1 in the recovery from depression
Psychophysiological disorders chronically impair brain functions, often accompanied by dysregulation of multiple genes, suggesting a multifaceted etiology behind the symptoms. To explore transcription factors (TFs) involved in such transcriptomic changes, we analyzed TF-activity profiles (TFAPs) from the brains of mice experienced chronic stress, and revealed alteration in TF-activity correlating with their pathophysiological phenotypes. We identified REST/NRSF and TCF/LEF associated with depressive phenotypes and discovered that neuropsychiatric drugs sertraline and lithium influence REST- and TCF/LEF-activity, both in vitro and in vivo, thereby affecting gene expression profiles. Pharmacological or genetic manipulation of REST- or TCF/LEF-activity in defeated mice impacts post-stress recovery from depressive phenotypes, with combined treatment further augmenting the outcomes. Our TFAP analysis enhances understanding of molecular mechanisms underpinning chronic diseases, aiding future therapeutic strategy development.
