Abstract

Background: Xuan-Fu-Hua decoction is a traditional Chinese medicine formula widely used for the treatment of inflammation-related disease in the lung and liver. This study aimed to investigate the effect of Xuan-Fu-Hua decoction treatment on liver cancer cells and its mechanism of action.

Methods: The impact of Xuan-Fu-Hua decoction treatment on the proliferation and apoptosis of SMMC-7721 liver cancer cells with or without 5-fluorouracil (5-FU) cotreatment was determined in both and settings. Alterations in gene expression patterns in SMMC-7721 cells induced by Xuan-Fu-Hua decoction treatment were explored by transcriptomic sequencing. Effective components of Xuan-Fu-Hua decoction and their target proteins were investigated using network pharmacology approaches.

Results: Xuan-Fu-Hua decoction alone did not significantly influence SMMC-7721 liver cancer cell growth, but it significantly increased the 5-Fu-induced growth inhibition and apoptosis of SMMC-7721 liver cancer cells and . Most differentially expressed genes in SMMC-7721 liver cancer cells with or without Xuan-Fu-Hua decoction treatment were enriched in cell apoptosis-related pathways. Xuan-Fu-Hua decoction treatment significantly increased the transcription levels of , and genes while decreasing that of , and genes. An interaction network between the effective components and their possible target proteins was constructed by predicting compound-target protein and protein-protein interactions. Gene set enrichment analysis revealed the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway as well as Bcl-2 and Mcl-1 proteins as potential regulatory targets of Xuan-Fu-Hua decoction in sensitizing SMMC-7721 cells to the cytotoxicity of 5-FU treatment.

Conclusions: Xuan-Fu-Hua decoction increased the sensitivity of liver cancer cells to the cytotoxicity of 5-FU treatment, possibly by potentiating cell apoptosis and inhibiting the prosurvival machinery.
