Finally, gene expression of key receptors involved in anxiety response, namely, α-estrogen receptor (ESR1), β-estrogen receptor (ESR2), α1 subunit of GABAA receptor (GABRA1), glutamate receptor subunit 1 (GRIN1), glucocorticoid receptor (GR), mineralocorticoid receptor (MR), and androgen receptor (AR) was evaluated in the hippocampus and the hypothalamus. This evidence concerns the gene NR3C1 and Anxiety.
