摘要:

基于网络药理学、分子对接技术挖掘马齿苋主要活性成分抑制奶牛乳腺炎的关键靶点,体外细胞试验验证其可能的作用机制。利用TCMSP数据库检索马齿苋的活性成分及对应靶点,使用GeneCards数据库和OMIM数据库检索奶牛乳房炎的疾病靶点,并于马齿苋活性成分靶点进行交集整合,并构建PPI网络。DAVID数据库进行GO功能富集分析和KEGG通路富集分析,AutoDock软件进行分子对接验证。最后,CCK-8法测定马齿苋提取物对奶牛乳腺上皮细胞的影响,LPS诱导MAC-T构建体外炎症模型,RT-qPCR检测关键靶点、IL-17信号通路以及炎症相关因子表达情况。结果显示:共筛选到马齿苋10种活性成分及188个对应靶点,从GeneCards和OMIM数据库中筛选出2 495个奶牛乳腺炎的相关靶点,通过Venn平台共找到40个共表达靶点。通过PPI网络得到ALB、TNF、IL6、IL1B、MMP9等10个关键靶点,涉及AGE-RAGE、脂质和动脉粥样硬化、癌症、IL-17、PI3K-AKT等信号通路。体外细胞试验表明,马齿苋能够增加MAC-T中ALB的含量,并提供IL-17信号通路下调炎症因子MMP9、TNF-αIL-6、IL-、IL-8、IFN-γ基因的转录,上调抑炎因子IL-10基因的转录。本研究揭示了马齿苋中能够通过抑制IL-17信号通路来抑制炎症因子的释放,从而抑制奶牛乳腺炎症反应。

Abstract:

Based on network pharmacology and molecular docking technology, the key targets of the main active components of Portulaca oleracea L. (POL) to inhibit mastitis in dairy cows were explored, and the possible mechanism of action was verified by in vitro cell experiments. The TCMSP database was used to search the active ingredients and corresponding targets of POL. The GeneCards database and OMIM database were used to search the disease targets of dairy cow mastitis, and the intersection and integration of the active ingredient targets of POL were carried out, and the PPI network was constructed. DAVID database was used for GO function enrichment analysis and KEGG pathway enrichment analysis, and AutoDock software was used for molecular docking verification. Finally, the effect of purslane extract on bovine mammary epithelial cells was determined by CCK-8 method. LPS induced MAC-T to construct an in vitro inflammation model. RT-qPCR was used to detect the expression of key targets, IL-17 signaling pathway and inflammation-related factors. Results showed that a total of 10 active components and 188 corresponding targets of POL were screened. A total of 2 495 targets related to mastitis in dairy cows were screened from the GeneCards and OMIM databases, and a total of 40 co-expressed targets were found through the Venn platform. Ten key targets such as ALB, TNF, IL6, IL1 B, and MMP9 were obtained through the PPI network, involving AGE-RAGE, lipid and atherosclerosis, cancer, IL-17, PI3K-AKT and other signaling pathways. In vitro cell experiments showed that purslane could increase the content of ALB in MAC-T, and provide IL-17 signaling pathway to down-regulate the transcription of inflammatory factors MMP9, TNF-α, IL-6, IL-1β, IL-8 and IFN-γ genes, and up-regulate the expression of anti-inflammatory factor IL-10 gene. This study revealed that purslane can inhibit the release of inflammatory factors by inhibiting the IL-17 signaling pathway, thereby inhibiting the inflammatory response of dairy cow mammary gland.
