Title | Untargeted and targeted mass spectrometry reveal the effects of theanine on the central and peripheral metabolomics of chronic unpredictable mild stress-induced depression in juvenile rats |
Overall design | The aim of this study was to explore the antidepressive effect of L-theanine and its related mechanisms in the chronic unpredictable mild stress (CUMS) model of depression. Sprague-Dawley rats were divided into the following 5 groups (n = 6 in each group): (1) control group, (2) CUMS group, (3) L-theanine group (stress with L-theanine treatment at the dose of 10 mg/kg), (4) CUMS + fluoxetine group (stress with fluoxetine treatment at the dose of 2 mg/kg), and (5) CUMS + L-theanine group (stress with L-theanine treatment at the dose of 10 mg/kg). Untargeted reversed-phase liquid chromatography-quadrupole-time-of-flight mass spectrometry and targeted hydrophilic interaction liquid chromatography-triple quadrupole mass spectrometry were developed to analyze the metabolism changes in the serum and hippocampus to screen for potential biomarkers related to L-theanine treatment. |
