摘要:

目的 采用网络药理学和计算机模拟探讨白头翁皂苷D(PSD)抑制三阴性乳腺癌(TNBC)侵袭转移的作用机制,并进行实验验证。 方法 运用Super-PRED、Swiss Target Prediction、PharmMapper、STITCH和BATMAN-TCM数据库收集PSD潜在靶点,利用GeneCards和OMIM数据库获得TNBC侵袭转移靶点,将两者相交获得药物-疾病交集靶点,利用Cytoscape3.10.1软件绘制“PSD-靶点-疾病”互作网络。运用Cytoscape3.10.1中的Centiscape2.2插件设定阈值并获得核心靶点,使用String数据库进行蛋白质互作(PPI)分析,通过David数据库对核心靶点进行KEGG通路和GO功能富集分析。最后将核心靶点依次与PSD进行分子对接。通过Transwell和Western blotting法对PSD的作用及机制进行验证。 结果 网络药理学结果显示,共筛选出PSD潜在靶点285个及药物与疾病核心靶点26个。GO分析获得175个条目,涉及生物大分子(蛋白质、DNA、RNA)的结合、酶活性、基因转录调控等方面。KEGG分析获得46个条目,涉及癌症途径、化学致癌-受体活化、癌症中的微小RNA、化学致癌-活性氧、癌症中PD-L1表达和PD-1检查点通路等。分子对接显示,PSD与MTOR、HDAC2、ABL1、CDK1、TLR4、TERT、PIK3R1、NFE2L2、PTPN1有较高的结合性。Transwell和Western blotting结果显示,PSD抑制TNBC细胞侵袭迁移且降低其MMP2、MMP9、N-cadherin及关键蛋白p-mTOR、ABL1、TERT、PTPN1、HDAC2、PIK3R1、CDK1、TLR4和细胞核内NFE2L2的表达(P<0.05),PSD可通过这些靶点阻碍TNBC侵袭转移。 结论 PSD通过多靶点和多途径抑制TNBC侵袭转移,为后续深入的机制研究提供前期基础,为TNBC药物研发提供新思路。

Abstract:

Objective To explore the mechanism by which Pulsatilla saponin D (PSD) inhibits invasion and metastasis of triple-negative breast cancer (TNBC). Methods The public databases were used to identify the potential targets of PSD and the invasion and metastasis targets of TNBC to obtain the intersection targets between PSD and TNBC. The "PSD-target-disease" interaction network was constructed and protein-protein interaction (PPI) analysis was performed to obtain the core targets, which were analyzed for KEGG pathway and GO functional enrichment. Molecular docking study of the core targets and PSD was performed, and the therapeutic effect and mechanism of PSD were verified using Transwell assay and Western blotting in cultured TNBC cells. Results Network pharmacology analysis identified a total of 285 potential PSD targets and 26 drug-disease intersection core targets. GO analysis yielded 175 entries related to the binding of biomolecules (protein, DNA and RNA), enzyme activities, and regulation of gene transcription. KEGG analysis yielded 46 entries involving pathways in cancer, chemical carcinogenesis-receptor activation, microRNAs in cancer, chemical carcinogenesis-reactive oxygen species, PD-L1 expression and PD-1 checkpoint pathway in cancer. Molecular docking showed high binding affinities of PSD to MTOR, HDAC2, ABL1, CDK1, TLR4, TERT, PIK3R1, NFE2L2 and PTPN1. In cultured TNBC cells, treatment with PSD significantly inhibited cell invasion and migration and lowered the expressions of MMP2, MMP9, N-cadherin and the core proteins p-mTOR, ABL1, TERT, PTPN1, HDAC2, PIK3R1, CDK1, TLR4 as well as NFE2L2 expressionin the cell nuclei. Conclusion The inhibitory effects of PSD on TNBC invasion and metastasis are mediated by multiple targets and pathways.
