OBJECTIVE To explore the pathogenesis of depression according to the LC-MS/MS-based metabolomics in the mouse model which exhibits social avoidance state induced by the chronic social defeat stress model(CSDS).METHODS Twenty male C57BL/6N mice were randomly divided into control group and model group suffering CSDS,and the ICR retired breeder mice were used to attack the model group for 14 d of chronic social defeated stress.The open field test and source preference test were both used to observe depression-like behavior.Besides,the social interaction test is used to observe the social interaction state,especially.After the stress,the serum samples of mice were collected,and the changes of endogenous metabolites were analyzed by LC-MS metabolomics technology,and the pathway analysis of the differential metabolites was performed to explore the pathogenesis of the CSDS induced depressive-like mouse model.RESULTS After the stress of CSDS was completed,the mice in the model group showed a significant slowdown in body weight growth,a reduction in the source preference rate,and a significant reduction in the total distance and the number of rearing in the open field test.Distinctively,the social interaction rate is remarkably decreasing.There are 24 differential metabolites found in the serum of CSDS model mice.CONCLUSION The mouse who suffered CSDS stress would show depressive-like behavior.Based on the LC-MS/MS metabolomics,24 differential metabolites were found in the serum of CSDS model mice.The amino acid metabolism might be significant to the pathogenesis of the CSDS induced depressive-like mouse model. 展开更多
