Core Tip

Core tip: Quantitative proteomic analysis was used to screen for differentially expressed proteins in the mediodorsal thalamic nucleus of rats subjected to restraint water-immersion stress. A total of 65 dysregulated proteins were identified, which are mainly involved in the neurological disease signalling pathways. Meanwhile, the 31 upregulated proteins are primarily related to cell division, whereas the 34 downregulated proteins are related to neuron morphogenesis and neurotransmitter regulation. Furthermore, glycogen synthase kinase-3 beta might be related to the central mechanism through which restraint water-immersion stress gives rise to stress-induced gastric ulcer (SGU). Proteomic analysis elucidated the nervous system molecular targets of SGU.
