Abstract:BACKGROUND: Wogonin (5, 7-dihydroxy-8-methoxyflavone) is a natural di-hydroxyl flavonoid extracted from the root of Scutellaria baicalensis乔治。本文旨在研究Wogonin在减轻急性肺损伤(ALI)中炎症和凋亡的作用机理。class =“ sub_abstract_label”>材料和方法: 脂多糖(LPS)用于建立ALI的体外模型。经过Wogonin处理后,通过CCK-8,TUNEL分析和Acridine Orame/溴化溴化物双染色,分别测量了LPS诱导的A549细胞的细胞活力和凋亡,而RT-QPCR,ELISA ASSAY,krotay,Krot blot估算了炎症细胞因子和氧化应激标记的含量。还进行了蛋白质印迹以评估所涉及的蛋白质的表达。随后,研究了Wogonin对SIRTUIN 1(SIRT1)介导的高运动组1蛋白(HMGB1)脱乙酰基的影响。 SIRT1 inhibitor EX527 was used to evaluate the regulatory effects of wogonin on SIRT1-mediated HMGB1 deacetylation in A549 cells under LPS stimulation.
RESULTS: LPS induced inflammation, oxidative stress and apoptosis of A549 cells,这被沃戈宁废除了。还发现Wogonin促进了HMGB1脱乙酰基,并伴有上调的SIRT1表达。 However, SIRT1 inhibitor EX527 partially reversed the protective effects of wogonin on the inflammation and apoptosis of LPS-induced A549 cells.
CONCLUSION: Wogonin alleviated the inflammation and apoptosis in LPS-induced A549 cells by SIRT1介导的HMGB1脱乙酰基化,这可能代表了一种新型机制的识别,该机制通过该机制对ALI发挥保护作用,并为将Wogonin应用于ALI治疗提供了思想。
