Abstract:
This study identified the anti-depression targets of Kaixin San(KXS) in the brain tissue with "target fishing" strategy, and explored the target-associated pharmacological signaling pathways to reveal the anti-depression molecular mechanism of KXS. The Balb/c mouse model of depression was established by chronic unpredictable mild stress(CUMS) and the anti-depression effect of KXS was evaluated by forced swimming test and sucrose preference test. KXS active components were bonded to the benzophenone-modified magnetic nanoparticles by photocrosslinking reaction for capturing target proteins from cortex, thalamus and hippocampus of depressive mice. The target proteins were identified by liquid chromatography-mass spectrometry/mass spectrometry(LC-MS/MS). The enrichment analysis on signaling pathways was performed by Cytoscape. The potential biological functions of targets were verified by immunohistochemistry and Western blot assay. The results showed that KXS significantly improved the behavioral indexes. There were 64, 91, and 44 potential targets of KXS identified in cortex, thalamus, and hippocampus, respectively, according to the target identification experiment. The functions of these targets were mainly associated with vasopressin-regulated water reabsorption, salmonella infection, thyroid hormone synthesis, and other signaling pathways. Besides, the results of immunohistochemistry and Western blot showed that KXS up-regulated the expressions of argipressine(AVP) in the cortex, heat shock protein 60(HSP60), cytochrome C oxidase 4(COX4), and thyrotropin-releasing hormone(TRH) in the thalamus, and down-regulated the expressions of tumor necrosis factor-α(TNF-α) and nuclear factor kappa B(NF-κB) p65 in the thalamus. Therefore, KXS may exert anti-depression effect through regulating vasopressin signaling pathway in the cortex and inflammation, energy metabolism, and thyroid hormone signaling pathways in the thalamus, and the effect of KXS on hippocampus is not significant.
