Title | Tryptophan-rich diet ameliorates chronic unpredictable mild stress induced depression- and anxiety-like behavior in mice: the potential involvement of gut-brain axis |
Overall design | In this study, a chronic unpredictable mild stress (CUMS)-induced mouse model with depression- and anxiety-like behaviors was used to evaluate the potential effects of tryptophan treatment on the depression, despair, and anxiety-like behavioral disorders. C57BL/6 mice were divided into the following 4 groups: (1) control group (no stress, with normal diet), (2) CUMS group (stressor, with normal diet), (3) tryptophan supplementation group (no stress, with tryptophan supplementation diet), and (4) CUMS + tryptophan supplementation group (stressor, with tryptophan supplementation diet). The CUMS stress procedure lasted for 5 weeks, and tryptophan supplementation was administered during the model building period. Targeted tryptophan metabolism in serum and untargeted metabolomics in the brain were detected by LC-MS (n = 6/group). |
