Down-regulation of Slit–Robo Pathway Mediating Neuronal Cytoskeletal Remodeling Processes Facilitates the Antidepressive-like Activity of Gastrodia elata Blume
2014
Nowadays, depression is a serious psychological disorder that causes extreme economic loss and social problems. Previously, we discovered that the water extract of Gastrodia elata Blume (WGE) improved depressive-like behavior by influencing neurotransmitters in rats subjected to the forced swimming test. To elucidate possible mechanisms, in the present study, we performed a proteomics and bioinformatics analysis to identify the related pathways. Western blot-validated results indicated that the core protein network modulated by WGE administration was closely associated with down-regulation of the Slit–Robo pathway, which modulates neuronal cytoskeletal remodeling processes. Although Slit–Robo signaling has been well investigated in neuronal development, its relationship with depression is not fully understood. We provide a potential hint on the mechanism responsible for the antidepressive-like activity of WGE. In conclusion, we suggest that the Slit–Robo pathway and neuronal cytoskeleton remodeling are possibly one of the pathways associated with the antidepressive-like effects of WGE.
