Abstract:
This study aims to investigate the effect and mechanism of the herb pair Agrimoniae Herba-Coptidis Rhizoma in inhibiting angiogenesis in the colorectal cancer inflammatory microenvironment by using the method of network pharmacology and the zebrafish model. The method of network pharmacology was employed to obtain the active components, potential core targets, and signaling pathways regulated by the herb pair in inhibiting angiogenesis in the inflammatory microenvironment of colorectal cancer, on the basis of which the underlying mechanism was predicted. The zebrafish model of colorectal cancer was established, and the inflammatory microenvironment was modeled. The effects of different concentrations of the herb pair on the area, number, and length of intersegmental vessels(ISVs) of the zebrafish model were observed. Western blot and real-time quantitative PCR were employed to measure the protein and mRNA levels, respectively, of vascular endothelial growth factor A(VEGFA), vascular epidermal growth factor receptor 2(VEGFR2, also known as kdrl, Flk1), and vascular epidermal growth factor receptor 3(VEGFR3, also known as Flt4). A total of 18 active components and 488 potential targets of Agrimoniae Herba-Coptidis Rhizoma were predicted, and 108 common targets were shared by the herb pair and the disease. According to the results of KEGG pathway enrichment analysis, the angiogenesis-related factors VEGFA, kdrl, and Flt4 in the VEGFA/VEGFR2 signaling pathway were selected for verification. The zebrafish experiment showed that compared with the blank group, the model group showed increased area, number, and length of ISVs in the inflammatory microenvironment. Compared with the model group, the herb pair decreased the area, number, and length of ISVs in a concentration-dependent manner. Compared with the blank group, the model group showed up-regulated protein and mRNA levels of VEGFA, kdrl, and Flt4 in the inflammatory microenvironment. Compared with the model group, the herb pair down-regulated the protein and mRNA levels of VEGFA, kdrl, and Flt4 in a concentration-dependent manner. The results indicated that in the colorectal cancer inflammatory microenvironment, the herb pair Agrimoniae Herba-Coptidis Rhizoma could inhibit angiogenesis via multiple components, targets, and pathways. The anti-angiogenesis effect might be related to the down-regulation of the expression levels of angiogenesis-related factors VEGFA, kdrl, and Flt4 in the VEGFA/VEGFR2 signaling pathway.
