Statistical analysis was performed using GraphPad Prism using one-way ANOVA.</p><p><strong>Results: </strong>Metabolomics combined with network pharmacology detected 2023 unique metabolites at the MS1 level and 216 metabolites at the MS2 level. Bhallataka taila metabolites were found to interact with 180 human target proteins identified through BindingDB analysis. These target proteins were mapped to key cancer regulatory signaling pathways, along with TNF-related apoptosis-inducing ligand (TRAIL), protease-activated receptor-1 (PAR1)-mediated thrombin signaling, Syndecan-1 and Glypican pathways, and vascular endothelial growth factor receptor (VEGFR)1/2 pathways. <i>In vitro</i> validation demonstrated that Bhallataka taila significantly regulated apoptosis (57%) and ROS production (56%) in A549 cells compared to control while modulating other cancer-related regulatory pathways.</p><p><strong>Conclusion: </strong>This data-driven study can help researchers identify promising cancer treatment candidates and validate their efficacy. This approach integrates traditional knowledge with modern scientific techniques to reinforce the anticancer potential of Bhallataka taila and its mechanisms.</p>","PeriodicalId":48614,"journal":{"name":"Bioimpacts","volume":"15 ","pages":"30568"},"PeriodicalIF":2.2,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12204778/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144530515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
