This study investigated the potential mechanisms of aged citrus peel (CP) in the treatment of oral squamous cell carcinoma (OSCC) using network pharmacology. Tangeretin was identified as the most crucial active ingredient in CP. Further analysis revealed core genes and essential pathways, and in vitro experiments demonstrated that tangeretin inhibits cell proliferation and induces apoptosis.
Oral squamous cell carcinoma (OSCC) is a malignant cancer and lacks ideal drugs. Aged citrus peel (Chenpi, CP) is an easily available traditional Chinese medicine (TCM) with potential anticancer effects. Network pharma-cology were used to investigate the potential mechanisms of CP in OSCC. Tangeretin was the most crucial active ingredient in CP, as shown by the establishment of the component-target-disease network (C-T-D). Protein-protein interaction (PPI) analysis and survival analysis showed that PIK3R1, ESR1, and CDK1 are core genes. Pathway enrichment analysis showed that PI3K-AKT is the top essential pathways. Molecular docking was used to predict the binding of targets and compounds. In vitro experiments showed that tangeretin inhibits cell proliferation, blocks the cell cycle in S phase, induces apoptosis, regulates core gene expression in SCC25 cells, and has lower toxicity to HOK cells. In conclusion, our study lays the foundation for the use of CP in the treatment of OSCC.
