背景:探讨四逆汤加参汤的抗肿瘤和抗病毒关键活性成分及其作用机制。
方法:采用网络药理学方法对SNRS的主要成分进行分析,槲皮素被确定为关键活性成分。然后,我们通过使用Drugbank获得槲皮素的靶标,PharmMapper,和SwissTargetPrediction数据库。然后,使用Genecards数据库获得HBV相关肝细胞癌(HBV相关HCC)的目标。此外,使用GEO数据库中HBV相关HCC患者的基因表达谱和GEPIA2数据库中生存差异最大的基因确定了槲皮素的潜在靶标。此外,通过GO研究潜在基因的机制,KEGG分析,和PPI网络。使用AUC和生存分析评估细胞周期蛋白依赖性激酶1(CDK1)和CCNB1的诊断和预后价值。最后,在体外验证槲皮素对Hep3B和HepG2215细胞增殖及CDK1和CCNB1水平的影响。采用ELISA检测槲皮素干预24h和48h后HepG2215细胞中乙型肝炎表面抗原(HBsAg)和乙型肝炎e抗原(HBeAg)的表达水平。
结果:确定了SNRS的前10个关键成分,槲皮素是最关键的成分。确定了101个潜在的槲皮素靶标用于治疗HBV相关的HCC。GO和KEGG显示101个潜在的靶向富集在癌症和细胞周期调控中。根据维恩分析,CDK1和CCNB1是交叉目标,可作为槲皮素对HBV相关HCC作用的潜在靶点。此外,CDK1和CCNB1在高危人群中高表达,而OS率较低。1年,CDK1和CCNB1的3年和5年曲线下面积(AUC)分别为0.724、0.676、0.622和0.745、0.678、0.634。此外,实验结果还表明,槲皮素抑制Hep3B和HepG2215细胞的增殖,降低CDK1的表达。HepG2215细胞上清液和细胞中HBsAg和HBeAg的表达随着槲皮素和CDK1抑制剂干预时间的增加而逐渐降低。
结论:槲皮素是抗HBV相关HCC活性的关键成分,通过抑制CDK1抑制SNRS中的HBV复制。
BACKGROUND: To explore the anti-tumor and anti-virus key active ingredients of Sini Decoction Plus Ginseng Soup (SNRS) and their mechanisms.
METHODS: The main ingredients of SNRS were analyzed by network pharmacology, and quercetin was identified as the key active ingredient. Then, we obtained the targets of quercetin by using Drugbank, PharmMapper, and SwissTargetPrediction databases. Then, the targets of HBV-related hepatocellular carcinoma (HBV-related HCC) were obtained by using Genecards database. In addition, using the gene expression profiles of HBV-related HCC patients in GEO database and the genes with the greatest survival difference in GEPIA 2 database identified the potential targets of quercetin. In addition, the mechanism of potential genes was studied through GO, KEGG analysis, and PPI network. Using AUC and survival analysis to evaluate the diagnostic and prognostic value of cyclin-dependent kinase 1 (CDK1) and CCNB1. Finally, the effects of quercetin on proliferation of Hep3B and HepG2215 cells and the level of CDK1 and CCNB1 were verified in vitro. ELISA was used to measure the expression levels of hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) after the intervention by quercetin for 24 h and 48 h in HepG2215 cell.
RESULTS: The first 10 key ingredients of SNRS were identified, and quercetin was the most key ingredient. The 101 potential quercetin targets were identified for the treatment of HBV-related HCC. GO and KEGG showed that 101 potential target enrichment in cancer and cell cycle regulation. By Venn analysis, CDK1 and CCNB1 were intersection targets, which could be used as potential targets for the action of quercetin on HBV-related HCC. Moreover, the expression of CDK1 and CCNB1 was highly expressed in the high-risk group, while the OS rate was low. The 1-year, 3-year and 5-year area under the curve (AUC) curves of CDK1 and CCNB1 were 0.724, 0.676, 0.622 and 0.745, 0.678, 0.634, respectively. Moreover, experimental results also showed that quercetin inhibited cell proliferation and reduced CDK1 expression in Hep3B and HepG2215 cells. The expressions of HBsAg and HBeAg in HepG2215 cell supernatant and cell gradually decreased with the increase of intervention time of quercetin and CDK1 inhibitor.
CONCLUSIONS: Quercetin is a key ingredient of anti-HBV-related HCC activity and inhibits HBV replication in SNRS by inhibiting CDK1.
