本研究利用网络药理学和分子对接技术探究迷迭香酸缓解家禽热应激的潜在作用机制,先通过PubChem和Genecards数据库分别获取迷迭香酸及热应激的潜在靶点,再构建“迷迭香酸—热应激—靶点”的网络关系以筛选核心靶点,同时进行GO富集分析和KEGG通路分析,最后将迷迭香酸和核心靶点逐一进行分子对接。结果显示,共筛选到37个相关靶点,其中核心靶点包括EGFR、MMP2和CASP3等8个。GO富集分析发现,37个相关靶点共涉及24个生物学过程(细胞外基质组织等),12个细胞成分(细胞质膜等)和15个分子功能(锌离子结合等)。KEGG通路分析表明,37个相关靶点涉及黏着斑、细胞黏附分子和MAPK信号通路等9条KEGG通路。分子对接结果显示,除与MMP1外,该成分与其余7个核心靶点的结合能均<-5 kJ/mol。综合表明,迷迭香酸可能通过作用于MMP2、MMP13、EGFR、MMP9、CASP3、MMP3和ESR1共7个核心靶点,调控MAPK、ErbB、GnRH等信号通路,从调控细胞凋亡与自噬、降低肠道损伤和保护繁殖功能等途径,缓解热应激对家禽造成的损伤。

The network pharmacology and molecular docking techniques were employed to investigate the potential mechanism of action by which rosmarinic acid alleviates heat stress in poultry. First, the PubChem and Genecards databases were used to obtain potential targets of rosmarinic acid and heat stress, respectively. Subsequently, a “rosmarinic acid-heat stress-target” network was constructed to screen for core targets, with simultaneous GO enrichment analysis and KEGG pathway analysis conducted. Finally, molecular docking was performed between rosmarinic acid and each core target individually. The results showed that a total of 37 related targets were screened, among which 8 were core targets including EGFR, MMP2, and CASP3. GO enrichment analysis revealed that these 37 related targets were involved in 24 biological processes (such as extracellular matrix organization), 12 cellular components (such as plasma membrane), and 15 molecular functions (such as zinc ion binding). KEGG pathway analysis indicated that the 37 related targets were associated with 9 KEGG pathways, including focal adhesion, cell adhesion molecules, and the MAPK signaling pathway. Except MMP1,molecular docking results demonstrated that the binding energies of other 7 core targets were less than -5 kJ/mol. Collectively, these findings suggested that rosmarinic acid may alleviate heat stress-induced damage in poultry by acting on 7 core targets (MMP2, MMP13, EGFR, MMP9, CASP3, MMP3, and ESR1), regulating signaling pathways such as MAPK, ErbB, and GnRH, and mediating processes including the regulation of cell apoptosis and autophagy, reduction of intestinal damage, and protection of reproductive function.
