Exploring the mechanism of genistein in treating hepatocellular carcinoma through network pharmacology and molecular docking

Abstract

Abstract Objectives Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death worldwide, with treatment options limited and outcomes often poor, especially in advanced stages. This study explores the therapeutic potential of genistein, a soybean-derived isoflavone, on HCC using network pharmacology to uncover its multi-targeted anti-cancer mechanisms. Methods Potential targets of genistein were predicted using databases such as Super-PRED, PharmMapper, and SwissTargetPrediction. Abnormally expressed genes in HCC tissues were analyzed from TCGA and GEO datasets, with genes linked to the prognosis of HCC patients selected as potential therapeutic targets. GO and KEGG pathway enrichment analyses were conducted for both genistein’s targets and the HCC-related gene set. Key targets were identified through network analysis using Cytoscape software. Molecular docking was performed with Autodock to assess the binding affinity between genistein and these key targets. The therapeutic effects of genistein on HCC were validated through animal experiments and cell line studies. Results This study identified 343 potential targets for genistein in treating hepatocellular carcinoma (HCC). Analyses revealed enrichment in cell cycle regulation pathways through GO and KEGG assessments. Transcriptomic data from HCC datasets unveiled 184 potential therapeutic targets, emphasizing cell cycle regulation. Notably, 12 proteins were identified as targets of both genistein and HCC treatment. Molecular docking studies demonstrated genistein’s strong binding affinity with CDC25C and MELK. In vitro and in vivo validations affirmed genistein’s role in inhibiting HCC proliferation by inducing G2/M phase arrest. This study elucidates genistein’s multi-target mechanism in suppressing HCC cell proliferation, supporting its potential clinical application in HCC treatment. Conclusions This study demonstrates that genistein effectively suppresses the malignant growth of HCC by interfering with the transition from the G2 to M phase, revealing a multifaceted mechanism of action.
