Recent studies indicated that zinc activates neural transmission via the GPR39 Zn2+-sensing receptor. Preclinical and clinical studies demonstrated the antidepressant properties of zinc. To investigate whether the GPR39 receptor is involved in the mechanism of antidepressant action, we measured the expression of the GPR39 receptor (Western Blot) in the frontal cortex of mice treated intraperitoneally with imipramine (30 mg/kg), escitalopram (4 mg/kg), reboxetine (10 mg/kg) or bupropion (15 mg/kg) for 14 days. The present study shows the up-regulation of the GPR39 receptor protein level after escitalopram (by 290%), reboxetine (by 816%) and bupropion (by 272%), but not imipramine treatment. This is the first report to indicate the involvement of the GPR39 Zn2+-sensing receptor in the antidepressant effect of selective monoamine reuptake inhibitors. (C) 2013 Elsevier Ltd.
