Abstract
With approximately 2 million lung cancer patients and 1.8 million deaths per year, the world ranks among the highest incidence rates in the world. Non-small cell lung cancer (NSCLC) accounts for up to 85% of lung cancer patients and has a poor prognosis. To investigate the mechanism
of Fuzheng Xiaoji Decoction in the treatment of NSCLC. Fuzheng Xiaoji Decoction, consisting of ten traditional Chinese medicines, was analyzed using the TCMSP database to identify its active ingredients and their corresponding targets. Simultaneously, NSCLC-related targets were obtained from
GeneCards. The study aimed to predict Fuzheng Xiaoji Decoction’s targets in treating NSCLC and establish a network diagram illustrating the relationship between traditional Chinese medicine, active ingredients, targets, and the disease. The STRING platform was used to construct a PPI
network, and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis and Gene Ontology (GO) function enrichment analysis were performed on the intersecting targets. Based on the interaction network analysis, the core target proteins, represented by the TOP5 nodes with the highest degrees,
were selected. These core targets were then subjected to molecular docking with the top five key active components of Fuzheng Xiaoji Decoction to construct the docking model. We identified 132 active components in Fuzheng Xiaoji Decoction and picked the TOP 5 proteins from the PPI network
as the primary active elements in Fuzheng Xiaoji Decoction for NSCLC treatment, including kaempferol, quercetin, ingenin, luteolin, and osterol, involving a total of 209 targets. The top five core targets obtained by PPI network were AKT1, TP53, STAT3, TNF and IL6. A total of 7879 targets
related to NSCLC were retrieved, and 164 drug-disease intersection targets were identified. GO functional analysis results showed that 164 gene sets were involved in 377 biological processes, mainly involved in 79 processes related to cell composition and 46 molecular function expression processes.
KEGG enrichment results showed 132 significantly enriched signaling pathways. Molecular docking findings indicated favorable binding interactions between the receptor and ligand, suggesting a strong affinity between the key NSCLC treatment protein and the primary active ingredient in Fuzheng
Xiaoji Decoction. The potential mechanism of Fuzheng Xiaoji Decoction in NSCLC treatment may involve flavonoids, triterpenoids and other compounds regulate lung cancer-related signaling pathways by acting on AKT1, TP53, STAT3 and other proteins to affect the expression of P53, IL6 and other
cytokines. This may help regulate immune function and inhibit tumor cell proliferation.
