目的
2
探讨柴胡皂苷d逆转乳腺癌放疗抵抗的分子机制。
方法
2
通过在线数据库预测柴胡皂苷d的潜在靶点,并从GEO数据库中获取乳腺癌放疗抵抗的差异性表达基因;筛选两者交集靶点,并进行网络拓扑分析、GO功能富集分析和KEGG通路富集分析。通过在线数据库分析核心靶点在正常乳腺组织和乳腺癌组织中的表达差异及其预后价值。利用分子对接技术验证柴胡皂苷d与核心靶点的相互作用。
结果
2
柴胡皂苷d逆转乳腺癌放疗抵抗的潜在靶点主要包括TP53、HSP90AA1、MYC、HSP90AB1、EGFR、H3-3B、JUN、HDAC1、CDK2、TGFB1、mTOR、RELA,这些靶点富集在PD-1/PD-L1、AGE-RAGE等多条信号通路上。HPA数据库分析发现,MYC、CDK2和HSP90AB1等在乳腺癌组织中表达相对较高;The Kaplan-Meier Plotter数据库分析发现,H3-3B、TGFB1、mTOR和RELA与乳腺癌的发生及预后显著相关。分子对接技术显示,柴胡皂苷d与核心靶点有着较好的结合能力。
结论
2
柴胡皂苷d可能通过H3-3B、mTOR、RELA等多个靶点及PD-1/PD-L1、AGE-RAGE等多条信号通路逆转乳腺癌放疗抵抗,为其临床应用提供了新的理论依据。
Objective
2
To investigate the molecular mechanisms of saikosaponin-d in reversing radioresistance of breast cancer.
Methods
2
The potential targets of saikosaponin-d were predicted using online databases, and differentially expressed genes associated with radioresistance of breast cancer were obtained from the GEO database. The intersecting targets were then screened, followed by network topology analysis, GO functional enrichment analysis and KEGG pathway enrichment analysis. The online databases were employed to assess the expression differences of the core targets between normal breast tissue and breast cancer tissue, as well as their prognostic significance. Molecular docking technology was used to verify the interaction between saikosaponin-d and core targets.
Results
2
The potential targets of saikosaponin-d in reversing radioresistance of breast cancer mainly included TP53, HSP90AA1, MYC, HSP90AB1, EGFR,H3-3B,JUN,HDAC1,CDK2,TGFB1,mTOR,and RELA,and these targets were enriched in multiple pathways such as PD-1/PD-L1 and AGE-RAGE. The HPA database revealed that MYC, CDK2, and HSP90AB1 were highly expressed in breast cancer tissues, and the Kaplan-Meier Plotter database showed that H3-3B, TGFB1, mTOR and RELA were significantly related to the occurrence and prognosis of breast cancer. Molecular docking technology demonstrated that saikosaponin-d has good binding ability to the core targets.
Conclusion
2
Saikosaponin-d may reverse the radioresistance of breast cancer through multiple core targets, including H3-3B, mTOR, and RELA, as well as multiple pathways including PD-1/PD-L1 and AGE-RAGE, thereby providing a new theoretical basis for its clinical application.
