Hepatocellular carcinoma (HCC) is a malignant tumor harmful to human health. Ganji Fang (GJF) has good clinical efficacy in the treatment of HCC, but its mechanism is still unclear. The aim of this study was to investigate the mechanism of action of GJF in the treatment of HCC through network pharmacology, molecular docking and experiments. A series of network pharmacology methods were used to identify the potential targets and key pathways of GJF in the treatment of HCC. Then, molecular docking technology was used to explore the binding ability of key active ingredients and targets in GJF. Multiple external databases were used to validate the key targets. In in vitro experiments, we performed MTT assays, wound-healing assays, cell cycle assays, apoptosis assays and RT‒qPCR to verify the inhibitory effect of GJF on the Human hepatoma G2 (HepG2) cells. A total of 162 bioactive components and 826 protein targets of GJF were screened, and 611 potential targets of HCC were identified. Finally, 63 possible targets of GJF acting on HCC were obtained. KEGG enrichment analyses showed that the top five pathways were the cell cycle, cellular senescence, p53 signaling pathway, PI3K/Akt signaling pathway, and progesterone-mediated oocyte maturation. Among them, we verified the PI3K/Akt signaling pathway. CCNE1, PKN1, CCND2, CDK4, EPHA2, FGFR3, CDK6, CDK2 and HSP90AAI were enriched in the PI3K/Akt pathway. The molecular docking results showed that the docking scores of eight active components of GJF with the two targets were all less than -5.0, indicating that they had certain binding activity. cell experiments showed that GJF could inhibit the proliferation and migration of HepG2 cells, block the cell cycle and induce apoptosis of HepG2 cells, which may be related to the PI3K/Akt signaling pathway. In summary, EPHA2 may be an important target of GJF in HCC, and pachymic acid may be an important critical active compound of GJF that exerts anticancer activity. In general, we demonstrated, for the first time, that the molecular mechanism of GJF in HCC may involve induction of G0/G1 phase cycle arrest through inhibition of the PI3K/Akt signaling pathway and promote apoptosis of hepatoma cell lines. This study provides a scientific basis for the subsequent clinical application of GJF and the in-depth study of its mechanism.
肝细胞癌(HCC)是一种对人类健康有害的恶性肿瘤。肝积方(GJF)在HCC治疗中具有良好的临床疗效,但其作用机制仍不清楚。本研究旨在通过网络药理学、分子对接和实验研究GJF治疗HCC的作用机制。采用一系列网络药理学方法确定GJF治疗HCC的潜在靶点和关键通路。然后,运用分子对接技术探究GJF中关键活性成分与靶点的结合能力。利用多个外部数据库对关键靶点进行验证。在体外实验中,我们进行了MTT实验、伤口愈合实验、细胞周期实验、凋亡实验和RT-qPCR,以验证GJF对人肝癌G2(HepG2)细胞的抑制作用。共筛选出GJF的162种生物活性成分和826个蛋白靶点,确定了611个HCC潜在靶点。最终获得63个GJF作用于HCC的可能靶点。KEGG富集分析显示,排名前五的通路为细胞周期、细胞衰老、p53信号通路、PI3K/Akt信号通路和孕酮介导的卵母细胞成熟。其中,我们验证了PI3K/Akt信号通路。CCNE1、PKN1、CCND2、CDK4、EPHA2、FGFR3、CDK6、CDK2和HSP90AAI在PI3K/Akt通路中富集。分子对接结果显示,GJF的8种活性成分与两个靶点的对接分数均小于-5.0,表明它们具有一定的结合活性。细胞实验表明,GJF可抑制HepG2细胞的增殖和迁移,阻断细胞周期并诱导HepG2细胞凋亡,这可能与PI3K/Akt信号通路有关。综上所述,EPHA2可能是GJF在HCC中的重要靶点,茯苓酸可能是GJF发挥抗癌活性的重要关键活性化合物。总体而言,我们首次证明GJF在HCC中的分子机制可能涉及通过抑制PI3K/Akt信号通路诱导G0/G1期细胞周期阻滞并促进肝癌细胞系凋亡。本研究为GJF后续的临床应用及其作用机制的深入研究提供了科学依据。
