Abstract:
Objective: A network model of ulcerative colitis-associated colon cancer (UCRCC) and NF-κB signaling pathway was established, in order to predict the key inflammatory targets of UCRCC and identify the effect of GQD and composition of index components on these targets. Methods: HPLC method was used, the mobile phase was acetonitrile-0.2% phosphoric acid aqueous solution, and the gradient elution was carried out. The 10 indicators were determined. The literature of databases such as Pubmed and ScienceDirect were searched, the terms of the upstream and downstream proteins of UCRCC disease and NF-κB pathway were examined. The Cytoscape software was used to predict the key inflammatory targets of UCRCC. The UCRCC model was established by AOM/DSS method, and the effect of GQD and composition of index components on key inflammatory targets were identified by immunohistochemistry and ELISA. Results: The contents of puerarin, daidzin, glycyrrhizin, jatrorrhizine, baicalin, palmatine, berberine, baicalein, glycyrrhizic acid and wogonin in GQD were 1.677, 0.154, 0.159, 0.045, 0.448, 0.035, 0.095, 0.013, 0.111 and 0.006 μg/g, respectively. The top eight inflammatory factors of the key protein in the interaction network were NF-κBp65, iNOS, COX-2, Bcl-2, TNF-α, IL-1β, ICAM-1 and VCAM-1. Compared with the model group, the high-, medium- and low-dose groups of GQD, the composition of index components group and the 5-ASA group were able to down-regulate the relative expression levels of NF-κBp65, iNOS, Bcl-2, COX-2 in colonic tissues of UCRCC mice (P < 0.01), and down-regulate the expression levels of TNF-α, IL-1β, ICAM-1, VCAM-1 in serum of UCRCC mice (P < 0.05, 0.01). Conclusion: GQD and composition of index components can improve the pathological condition of colon tissue in UCRCC mice, down-regulate the expression of inflammatory factors in colon tissue of UCRCC mice, and have a certain intervention effect on UCRCC, which laid the foundation for determining the quality marker (Q-marker) of GQD.
