Abstract:
Objective:To study the biological basis of Banxia Xiexintang against chronic gastritis by using quantitative proteomics. Method:The experimental rats were divided into normal group，chronic gastritis model group，and Banxia Xiexintang group. The chronic gastritis model was established four weeks later by gavage with 56% ethanol. After treatment，the stomach tissues were stained with hematoxylin and eosin （HE） to observe the histopathological damage and improvement of gastric tissue in each group. The protein in gastric tissue was extracted. The differential proteins among different groups were studied by quantitative proteomics using tandem mass spectrometry tag（TMT），and the key differentially expressed proteins（DEPs） were verified by Western blot. Result:A total of 4 452 proteins were identified from rat stomach tissues，of which 318 proteins were different between the model and the normal group. After the intervention of Banxia Xiexintang，compared with the model group，there were a total of 258 differential proteins， which were mainly enriched in cell killing，nucleoid and hijacked molecular function. Kyoto encyclopedia of genes and genomes（KEGG） pathway enrichment included tricarboxylic acid（TCA） cycle，steroid hormone biosyntheis，and Retrograde endocannabinoid signaling，as well as phosphatidylinositol 3-kinase（PI3K）/protein kinase B（Akt），nuclear transcription factor-κB（NF-κB） signal pathways. Western blot verification found that 14-3-3 theta，Tenascin-C，ntercellular adhesion molecule-1（ICAM-1），stem cell factor（SCF），Caspase-3，GTPase of the Immunity-associated protein 4（GIMAP4） and mitochondrial pyruvate carrier 1（Mpc1） might be the crucial proteins for the treatment of chronic gastritis. Conclusion:The mechanism of Banxia Xiexintang in the treatment of chronic gastritis involves energy metabolism，hormone regulation，inflammation and immune processes. The target proteins found by differential proteomics and the signaling pathways may be the biological basis of Banxia Xiexintang in the treatment of chronic gastritis.
