An Investigation of the Effect of the Traditional Naxi Herbal Formula Against Liver Cancer Through Network Pharmacology, Molecular Docking, and In Vitro Experiments

<b>Background/Objectives</b>: The formula Chong-Lou-Yao-Fang (CLYF) is an herbal medicinal formulation developed by the indigenous Naxi people for treating liver cancer. This study was to reveal the biological activity, potential targets, and molecular mechanisms of CLYF for cancer treatment. <b>Methods</b>: Network pharmacology, microarray data analysis, survival analysis, and molecular docking were employed to predict potential compounds, targets, and pathways for the treatment of liver cancer. In vitro experiments and Western blot validation were conducted to confirm these predictions. <b>Results</b>: 35 key compounds and 20 core targets were screened from CLYF, involving signaling pathways for PI3K-Akt, MAPK, hepatitis B and C, which were effective for liver cancer treatment. Microarray data analysis and survival analysis indicated that EGFR and TP53 serve as promising biomarkers for diagnosis and prognosis in liver cancer. Molecular docking revealed stable binding between EGFR, TP53, and AKT1 with active ingredients. Cell experiments confirmed that CLYF-A suppressed cell proliferation, induced apoptosis, and caused cell cycle arrest in HepG2 cells, which were associated with a loss of mitochondrial membrane potential. Compared to the control group, the relative protein expression levels of EGFR and AKT1 significantly decreased following treatment with CLYF-A, while TP53 levels increased significantly. <b>Conclusions</b>: Verification of the anticancer activity of CLYF and its potential mechanisms may have important implications for anticancer therapies. Our results may provide a scientific basis for the clinical use of CLYF for cancer treatment and have important implications for developing pharmaceutical preparations, which also need more pharmacological experiments, clinical experiments, and in vivo experiments.
