A relation between magnesium (Mg) status and mood disorders has been suggested, but evidence remains inconsistent. Therefore, we examined in mice whether Mg-depletion would alter behavior evaluated in established animal models of depression and anxiety and whether these effects would be sensitive to antidepressants. Compared to control mice fed with normal diet, mice receiving a low Mg diet (10% of daily requirement) for several weeks displayed increased immobility time in the forced swim test, indicating enhanced depression-like behavior. In addition, the partial Mg-depletion increased anxiety-related behavior in the light/dark and open field test, while locomotor activity or motor coordination was not influenced. Chronic oral administration of desipramine (30 mg/kg/day), or Hypericum extract LI160 (Hyp, 380 mg/kg/day) prevented the "pro-depression-like" forced swim behavior in Mg-depleted mice. Furthermore, the increase in anxiety-related behavior of Mg-depleted mice was abolished in both the open field and light dark test by Hyp. Taken together, we report that Mg-depletion leads to enhanced depression- and anxiety-related behavior in mice, which was further validated by the reversibility of the behavioral changes by known antidepressant and anxiolytic substances. Further, the utility of Mg-depletion as a new screening model for clinically active antidepressant and anxiolytic drugs is suggested.
