Abstract B072: Molecular targets of caffeine in breast cancer treatment: A network pharmacology approach

Abstract

Abstract In Ghana, breast cancer leads in female cases (31.8%), demanding advanced treatments. Rising caffeine-filled energy drinks raise concerns. Yet, caffeine's role in breast cancer lacks understanding, urging more research. Our study uses network pharmacology and molecular docking to unravel the intricate molecular targets of caffeine in breast cancer, offering new therapies for this widespread disease We identified breast cancer-related targets from GEO datasets and TCGA databases, while caffeine targets were obtained from the SwissTarget Prediction database and literature. Common targets of both caffeine and breast cancer were considered using Venny software. PPI networks were generated using STRING and Cytoscape, identifying hub genes. Target proteins were annotated using the GO database, and pathway enrichment analysis was performed using KEGG. To investigate the binding affinity target proteins were retrieved from the Protein DataBank and docking studies were conducted using AutoDock Vina to explore the binding interactions between caffeine and potential target proteins identified. We identified 108 targets, and 6 common targets, including Cyclin-Dependent Kinase 1, Cyclin B1, Epidermal Growth Factor Receptor, Cyclin B2, Monoamine Oxidase A, and Carbonic Anhydrase 12 in relation to breast cancer. Gene Ontology (GO) and KEGG pathway enrichment analysis revealed their interactions in key pathways such as the P53 signaling pathway and Foxo signaling pathway, suggesting their critical roles in anti-breast cancer processes. Notably, caffeine exhibited the best overall binding affinity when interacting with CDK1, CCNB1, EGFR, and CCNB2 These findings provide valuable insights into the potential molecular targets and pathways associated with caffeine's anti-breast cancer effects, offering new strategies for therapeutic strategies.
