摘　　要：探索阔叶十大功劳Mahonia bealei调控铁死亡干预肝癌的机制.从GEO数据库下载肝癌的转录组数据集,从FerrDb数据库下载铁死亡相关基因,使用TCMSP、SymMap、SwissTargetPrediction数据库获取M.bealei的成分与靶点;使用DS BIOVIA Discovery Studio 2016 v16.1软件进行分子对接;运用Cytoscape软件及STRING平台,对药物-疾病-铁死亡交集靶点进行PPI分析;利用GEPIA、TIMER数据库进行差异表达分析;利用UALCAN数据库进行临床相关性分析;利用Kaplan-Meier Plotter数据库进行生存分析;使用THPA数据库进行病理学切片分析;使用Western blot进行体外实验验证;最后,进行转录因子的预测,共筛选出5个M.bealei调控铁死亡干预肝癌的关键基因,通过基因差异表达选取3个核心基因AKR1C3、AKR1C1、AURKA,进一步分析发现AURKA与肝癌生存分析、临床参数、病理学结果均显著相关.Western blot实验证实,与HepG2肝癌细胞组相比,M.bealei含药血清组的AURKA蛋白表达上调(P<0.05).通过以上研究认为M.bealei可通过作用于AURKA调控铁死亡而干预肝癌.Through network pharmacology and bioinformatics,we explored the mechanism of Mahonia bealei regulating ferroptosis to interfere with liver hepatocellular carcinoma(LIHC).LIHC gene chip data set was downloaded from GEO database,ferroptosis markers were downloaded from FerrDb database,components and targets of M.bealei were obtained from TCMSP,SymMap and SwissTargetPrediction database.Molecular docking was performed using DS BIOVIA Discovery Studio 2016 v16.1 software to search for hub genes;Using Cytoscape software and STRING platform,PPI analysis was performed on the intersection targets of drug-disease-ferroptosis.The GEPIA and TIMER database were used for differential expression analysis.Clinical correlation analysis was performed using UALCAN data.Kaplan-Meier Plotter database was used for survival analysis.Pathology section analysis was performed using the THPA database.We used Western blot to Verify in vitro experiments Finally,transcription factor prediction and cell experiments were performed.A total of 5 hub genes regulating ferroptosis and interfering LIHC were screened out.Three core genes,AKR1C3,AKR1C1 and AURKA,were selected through gene differential expression.Further analysis found that AURKA was significantly correlated with LIHC survival analysis,clinical parameters and pathological results.We also verified that AURKA protein expression was up-regulated in M.bealei containing serum group compared with HepG2 hepatocellular carcinoma group by Western blot assay(P<0.05).Through the above research,we believe that the M.bealei can intervene in LIHC by acting on AURKA to regulate ferroptosis.
