Abstract

Recent reports suggest that FKBP5 gene and its corresponding FKBP5 protein play a relevant role in the regulation of anxiety and depression in animal models and human stress-related disorders. In the present study, FKBP5 and glucocorticoid receptor (GR) gene and protein expression were analyzed in the amygdala (AMY) of suicide victims (n=13 males, without clinical psychiatric history and non-treated with anxiolytic or antidepressant drugs) and its corresponding controls (n=13 males) by real-time PCR and Western blotting. The results revealed that FKBP5 and GR gene expression were significantly reduced in the AMY (-38% and -48%, respectively) of suicide victims compared with controls. Interestingly, FKBP5 and GR protein expression were also significantly decreased (-41% and -42%, respectively) in the AMY of suicide victims compared with controls. These results suggest that the FKBP5 plays a relevant role in human emotional responses and suggest this receptor as a new promising target in the treatment of suicide behavior.
