摘要

Dioxin-like pollutants, especially 2,3,7,8-Tetrachlorodibenzo-p-dioxin, are recognized human carcinogens. Retrospective studies suggest a link between dioxins and soft tissue sarcomas, including liposarcoma, but mechanisms remain unclear. This study explores the toxicological effects of dioxins on liposarcoma, identifies key proteins, and proposes potential solutions. We identified dioxin- and liposarcoma-related targets via databases, analyzed overlaps through enrichment and network toxicology, and validated them with phenotypic and clinical data. We built a prediction model using 117 combinations of machine learning algorithms, confirmed the results with molecular docking and simulations, and proposed therapies through drug experiments. TCDD modulates adipocytic malignancy through activation of xenobiotic response pathways, disruption of cellular metabolism, and interactions with cancer-related receptors. AhR partially mediates this toxicological effect, and five key proteins, including CDH3, ADORA2B, MMP14, IP6K2, and HTR2A, are used to predict the development of dioxin-related liposarcoma. The selective HTR2A receptor antagonist ketanserin has the potential to alleviate this toxicological impact. Our study presents an efficient, cost-effective toxicological analysis using network toxicology, offering new insights into dioxin-associated liposarcoma.
