Bisphenol F (BPF) has gained prominence as an alternative to bisphenol A (BPA) in various manufacturing applications, yet being detected in diverse environments and posed potential public health risk. This research aims to elucidate the putative toxic targets and underlying molecular mechanisms of prostate injury induced by exposure to BPF through multi-level bioinformatics data, integrating network toxicology and molecular docking. Systematically leveraging multilevel databases, we determined 276 targets related to BPF and prostate injury. Subsequent screenings through STRING and Cytoscape tool highlighted 27 key targets, including BCL2, HSP90AA1, MAPK3, ESR1, and CASP3. GO and KEGG enrichment analyses demonstrated enrichment of targets involved in apoptosis, abnormal hormonal activities, as well as cancer-related signal transduction cascades, ligand-receptor interaction networks, and endocrine system signaling pathways. Molecular docking simulations conducted via Autodock corroborated high-affinity binding interaction between BPF and key targets. The results indicate that BPF exposure can contribute to the initiation and progression of prostate cancer and prostatic hyperplastic by modulating apoptosis and proliferation, altering nerve function in blood vessel endothelial cells, and disrupting androgen metabolism. This study offers theoretical underpinnings for comprehending the molecular mechanisms implicated in BPF-elicited prostatic toxicity, while concomitantly establishing foundational framework for the development of prophylactic and therapeutic strategies for prostatic injuries related to polycarbonate and epoxy resin plastics incorporated with BPF, as well as environments afflicted by elevated levels of these compounds.
双酚 F(BPF)作为双酚 A(BPA)的替代品在各种制造应用中受到关注,但已在各种环境中被检测到,并构成潜在的公共健康风险。本研究旨在通过多层次生物信息学数据,整合网络毒理学和分子对接,阐明 BPF 暴露致前列腺损伤的潜在毒性靶标和分子机制。系统利用多层次数据库,我们确定了 276 个与 BPF 和前列腺损伤相关的靶点。随后通过 STRING 和 Cytoscape 工具筛选出 27 个关键靶点,包括 BCL2、HSP90AA1、MAPK3、ESR1 和 CASP3。GO 和 KEGG 富集分析表明,目标涉及细胞凋亡、异常激素活动以及与癌症相关的信号转导级联、配体-受体相互作用网络和内分泌系统信号通路的富集。通过 Autodock 进行的分子对接模拟证实了 BPF 与关键靶标之间的高亲和力结合相互作用。结果表明,BPF 暴露可通过调节细胞凋亡和增殖、改变血管内皮细胞的神经功能以及破坏雄激素代谢,导致前列腺癌和前列腺增生的发生和发展。本研究为理解 BPF 诱发的前列腺毒性所涉及的分子机制提供了理论基础,同时为开发与聚碳酸酯和环氧树脂塑料中 BPF 相关的前列腺损伤的预防和治疗策略以及受这些化合物影响的环境奠定了基础。
