In this study, colorectal cancer (CRC)-diseased targets and resveratrol (Res)-associated targets were combined and constructed by the use of grouped databases for identification of the predicted targets. After production of target-functional protein interaction network of Res anti-CRC, the topological analysis was used to create the core targets of Res anti-CRC. All core targets performed the analyses of biological function and pathway enrichment to optimize the biological processes and key signaling pathways of Res anti-CRC. The resultant five core therapeutic targets of Res anti-CRC were identified as protein kinase B1 (AKT1), interleukin 6 (IL6), Tumor protein p53 (TP53), vascular endothelial growth factor, and mitogen-activated protein kinase 1, respectively. Biological processes of Res anti-CRC were predominantly associated with regulating apoptosis, immune response, cellular communication, signal transduction, and metabolism of the nuclide. In addition, the top 10 key signaling pathways were identified, respectively. In human CRC sample assays, CRC histologic sections showed elevated expression of AKT1 and IL6 proteins, accompanied with abnormal changes in blood molecules. In pharmacological experiments of Res anti-CRC in vitro, Res-treated HCT116 cells showed inhibited cell growth, induced cell death. In addition, downregulation of intracellular AKT1 and IL6 expression were checked in Res-treated HCT116 cells. Taken together, these bioinformatic findings and preliminary validated data uncovered pharmacological molecular mechanisms associated with Res anti-CRC, and further identified top five core therapeutic targets. Beneficially, these five predicted targets might serve as potential biomolecules for anti-CRC treatment.
在本研究中,通过使用分组数据库将结直肠癌(CRC)相关靶点和白藜芦醇(Res)相关靶点进行合并与构建,以识别预测靶点。在构建Res抗CRC的靶点-功能蛋白相互作用网络后,利用拓扑分析确定Res抗CRC的核心靶点。对所有核心靶点进行生物学功能和通路富集分析,以优化Res抗CRC的生物学过程和关键信号通路。结果确定Res抗CRC的五个核心治疗靶点分别为蛋白激酶B1(AKT1)、白细胞介素6(IL6)、肿瘤蛋白p53(TP53)、血管内皮生长因子和丝裂原活化蛋白激酶1。Res抗CRC的生物学过程主要与调节细胞凋亡、免疫反应、细胞通讯、信号转导和核素代谢有关。此外,还分别确定了前10条关键信号通路。在人CRC样本检测中,CRC组织切片显示AKT1和IL6蛋白表达升高,同时血液分子发生异常变化。在Res抗CRC的体外药理学实验中,Res处理的HCT116细胞显示出细胞生长受到抑制、细胞死亡。此外,在Res处理的HCT116细胞中检测到细胞内AKT1和IL6表达下调。综上所述,这些生物信息学研究结果和初步验证数据揭示了与Res抗CRC相关的药理分子机制,并进一步确定了前五个核心治疗靶点。有益的是,这五个预测靶点可能作为抗CRC治疗的潜在生物分子。
