Title

Early-life stress induces depression-like behavior and synaptic-plasticity changes in a maternal separation rat model: gender difference and metabolomics study

Overall design

The aim of this study was to explore the mechanism of the maternal separation (MS) rat model in depression-like behavior in adult rats. Sprague-Dawley rats were divided into the following 4 groups: (1) male control group, (2) male MS group, (3) female control group, and (4) female MS group. From postnatal day (PND) 1 to 21, the pups of the MS groups were separated from their dams for 6 hours daily. Effect of MS on sex hormones and their metabolites was investigated by LC-MS. Differential metabolites in brain tissues were investigated by LC-MS-based untargeted metabolomics analysis. Six samples per group were used for metabonomic analysis.
