Abstract
The present study investigated whether 3,4,5-trimethoxycinnamic acid (TMCA) treatment ameliorated restraint stress-provoked anxiety- and depression-like behaviors in mice. Fourteen consecutive days of restraint stress produced anxiety- and depression-like behaviors, including reduced time and frequency in the open arms of the elevated plus maze (EPM), as well as enhanced immobility times in the forced swim test (FST). However, TMCA (50Â mg/kg) treatment ameliorated this effect; mice showed increased time and frequency of visits in the open arms of the EPM and showed reduced immobility in the FST. In parallel with the behavioral data, long-lasting stimulation of ÎFosB in the nucleus accumbens shell subregion was exhibited in response to TMCA. Furthermore, a reduction in expression of SC1, a target of ÎFosB, in the nucleus accumbens of mice subjected to restraint stress was significantly reversed by TMCA (50Â mg/kg) treatment. Collectively, these results suggest that TMCA treatment might provide a therapeutic strategy for treatment of anxiety and depression.
