NR1D1 and Anxiety: In addition, we assessed the expression of specific stress-responsive genes—glucocorticoid and mineralocorticoid receptors, Nr3c1 and Nr3c2 (which are important mediators of the stress response and interact with proteins that are activated by neuronal activity [34]) and Nr1d1, which encodes the transcription factor REVERBα modulating sociability and anxiety-related behavior [35].
