In recent years, the incidence rate of thyroid cancer is on the rise, posing a serious threat to human health. Therefore, this study reviews the targeted drugs currently used for the treatment of thyroid cancer and analyzes them using network pharmacology methods to reveal their mechanisms of action and potential therapeutic targets, providing new ideas for further research and clinical practice of the applications of targeted drug in thyroid cancer. Methods: First, a search was done on the current targeted drugs for the treatment of thyroid cancer by searching relevant literatures, including sorafenib, lenvatinib, vandetanib, cabozantinib and so on. Then, exploring from the perspective of network pharmacology, DrugBank, Uniprot databases, literature searches were used to identify molecular targets and drug targets. GeneCards, DrugBank and databases were searched and the VENNY 2.1 website was used to construct a Venn diagram by combining the obtained effective ingredient targets with thyroid cancer targets. Protein-Protein Interaction Networks and Drug-Potential Active Ingredient-Target Interaction Networks (PPI) were constructed using STRING database and Cytoscape software. Gene Ontology (GO) functional analysis and Kyoto Encyclopedia of Genes and Genomes (KEEG) pathway enrichment analysis were further conducted on common targets through the DAVID database to screen for key pathways. GO network diagrams, KEGG diagrams and key target pathways diagrams were drawn using Microbiology Data to reveal the possible mechanisms of drug functions. Results: Currently, the targeted therapeutic drugs for thyroid cancer mainly include molecular targeted drugs such as sorafenib, lenvatinib, vandetanib, cabozantinib and so on. Based on databases and software screening, the effective ingredients and related targets were determined. Combining with the drug-component-target network diagram, the importance of some targets in embryonic development, cell proliferation, and other aspects were revealed. Analyzing GO functional enrichment revealed that drugs exert their effects by regulating biological processes such as multicellular biological development and cell proliferation. KEGG functional enrichment analysis showed that multiple pathways such as MAPK signaling pathway and PI3K-AKT signaling pathway and so on were highly correlated with the treatment of thyroid cancer. Conclusion: We analyzed the current targeted drugs for the treatment of thyroid cancer and their mechanisms of function, revealing that clinical drugs intervene in the treatment of the occurrence and development of thyroid cancer through multiple pathways. At the same time, the constructed drug-component-target network and functional enrichment analysis provide important references for further clinical integrated therapy. 展开更多
