- Abstract: Aim To investigate the molecular mechanisms of alcohol extracts of Euphorbia fischeriana steud. against hepatocellular carcinoma (HCC) through a combination of network pharmacology analysis and experimental validation. Methods The active ingredients and targets of alcohol extracts of Euphorbia fischeriana steud. were determined through TCMSP, Swiss ADME, Swiss Target Prediction database and references. The databases DisGeNET and GeneCards were employed to screen potential HCC-related genes. Venny platform, STRING platform and Cytoscape software were applied to construct active ingredient-target-disease and protein-protein interaction (PPI) network maps. Gene ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) enrichment analyses were performed using the DAVID database. To assess the effects of Euphorbia fischeriana steud. alcohol extracts on BEL-7402 cells, the proliferation and apoptosis were detected by CCK-8, EdU and flow cytometry assays, and the related protein levels of JAK2/STAT3 pathway were analyzed by Western blot. Additionally, H22 hepatocellular carcinoma mouse model was used to evaluate the in vivo efficacy of Euphorbia fischeriana steud. alcohol extracts. Results A total of 916 HCC targeted genes, 30 active ingredients containing the related 567 potential targeted genes, and 115 intersection targets of disease and compounds were obtained. KEGG enrichment analysis identified JAK2/STAT3 signaling as a critical pathway. In vitro experiments showed the alcohol extracts of Euphorbia fischeriana steud. could inhibit proliferation, promote apoptosis and suppress JAK2/STAT3 signaling pathway in a dose-dependent manner in BEL-7402 cells. In addition, the alcohol extracts of Euphorbia fischeriana steud., either alone or in combination with sorafenib, dramatically blocked tumor growth in in vivo tests. Conclusions Euphorbia fischeriana steud. alcohol extracts have anti-cancer effects in HCC, and the molecular mechanisms may be connected to the regulation of JAK2/STAT3 signaling pathway.
