摘要:
对象: 动脉粥样硬化(AS)是由慢性炎症引起的。苯酯(ART)是一种从中草医学中分离出的倍半萜内酯内氧化苯甲酸酯,表现出极好的抗炎活性。在这项研究中,我们调查了青霉素对APOE敲除小鼠动脉粥样硬化的影响,并使用了未靶向的代谢组学进行在ART治疗后,确定这些小鼠的代谢物变化。
方法: apoe敲除小鼠被喂食西方饮食,并施用了八周的艺术。使用非靶向代谢组学来检测ART给药后的差异代谢产物。 Oil Red O was used to assess plaque size, western blot and ELISA were used to detect inflammatory factors, and flow cytometry was used to detect the expression of markers on macrophages.
RESULTS: Results of the in vivo experiment suggested that ART reduced atherosclerotic plaques in murine aortic 根。此外,体内和体外实验都表明,ART降低了炎症细胞因子的表达水平,但增强了巨噬细胞中抗炎细胞因子的表达水平。未靶向的代谢组学分析表明,被阻塞在AS小鼠中的多个代谢途径显示出DIF艺术治疗后,改善程度。此外,生物信息学分析表明,在AS小鼠和ART治疗小鼠中,HIF-1α途径改变了。 In vitro experiments confirmed that LPS-induced upregulation of HIF-1α expression and activation of the NF-κB signaling pathways was significantly inhibited by ART treatment.
CONCLUSION: These results suggest that ART exerts anti-atherosclerosis effects by inhibiting M1 macrophage polarization.分子机制之一是ART通过调节HIF-1α和NF-κB信号通路抑制M1样巨噬细胞极化。
