Title | Oral administration of 5-hydroxytryptophan restores gut microbiota dysbiosis in a mouse model of depression |
Overall design | The aim of this study was to determine the effects of 5-hydroxytryptophan on the mouse gut microbiome. Both the high-fat diet and chronic unpredictable stress (CUS) were used to induce the depression phenotype in mice. C57BL/6J mice were divided into the following 4 groups (n = 8/group): (1) control group (normal diet, no stress), (2) control + 5-hydroxytryptophan group (normal diet, no stress, with 5-hydroxytryptophan treatment at the dose of 100 mg/kg), (3) CUS + high-fat diet group (high-fat diet and stress), and (4) CUS + high-fat diet + 5-hydroxytryptophan group (high-fat diet and stress, with 5-hydroxytryptophan treatment at the dose of 100 mg/kg). For the first 5 weeks, mice received CUS stress or no stress. Then mice were orally gavaged daily with 5-hydroxytryptophan or vehicle for 8 weeks. The concentrations of 11 short-chain fatty acids in the serum samples of mice in the four groups were determined using GC-MS analysis. |
