Abstract:
The present study investigated the effects and mechanisms of Jiaotai Pills on depressed mice induced by chronic unpredictable mild stress(CUMS). The CUMS-induced depression model mice were established and the depression behaviors of mice were evaluated by sucrose preference test, open field test, tail suspension test, and forced swimming test. Molecular docking was employed to simulate the interaction of six main active ingredients in Jiaotai Pills with SIRT1. Immunohistochemical staining was used to detect the level of SIRT1 in the hippocampus of mice. Western blot was used to detect the protein expression levels of SIRT1, p-NF-κB p65, NF-κB p65, and FoxO1 in the hippocampus of mice. Enzyme-linked immunosorbent assay(ELISA) kits were used to detect the levels of interleukin(IL)-1β, IL-6, tumor necrosis factor-α(TNF-α), and brain-derived neurotrophic factor(BDNF) in the hippocampus and serum of mice. Biochemical kits were used to detect superoxide dismutase(SOD) activity and malondialdehyde(MDA) and glutathione(GSH) levels in the hippocampus and serum of mice. Liquid chromatography-tandem mass spectrometry(LC-MS/MS) was used to detect the levels of dopamine(DA), 5-hydroxytryptamine(5-HT), and norepinephrine(NE) in the hippocampus and serum of mice. The results showed that the sucrose preference rate, movement distance, and the number of crossing centers were reduced in the model group(P<0.01), and the tail suspension time and swimming immobility time were increased(P<0.01). Molecular docking results indicated good binding of six main active ingredients in Jiaotai Pills to SIRT1. In the hippocampus, the expression level of SIRT1 was reduced(P<0.01), and the levels of p-NF-κB p65/NF-κB p65 and FoxO1 were increased(P<0.01). In the hippocampus and serum, the levels of IL-1β, IL-6, TNF-α, and MDA were increased(P<0.01), and the activity of SOD and the levels of GSH, DA, 5-HT, NE, and BDNF were reduced(P<0.01). The treatment with high-dose Jiaotai Pills increased the sucrose preference rate, movement distance, and the number of crossing centers(P<0.05), reduced tail suspension time and swimming immobility time(P<0.01), elevated hippocampal SIRT1 expression level(P<0.01), decreased hippocampal and serum IL-1β, IL-6, TNF-α, and MDA levels(P<0.01), potentiated SOD activity, and up-regulated GSH, DA, 5-HT, NE, and BDNF levels in the hippocampus and serum(P<0.05, P<0.01) in model mice. In conclusion, the results showed that Jiaotai Pills could improve the depression behaviors of model mice with CUMS-induced depression, and the underlying mechanism was related to the up-regulation of SIRT1 in the hippocampus of mice to exert anti-inflammatory and anti-oxidative stress effects.
