目的 通过转录组学分析探讨多发性硬化(MS)中铁死亡基因免疫浸润及综合网络调控.方法 采用转录组学分析方法鉴定MS中相关铁死亡基因表达,通过GO和KEGG进行富集分析.运用LASSO和SVM-RFE算法识别MS中的关键铁死亡基因,采用ROC曲线分析评价其诊断效能.构建MS小鼠模型通过qRT-PCR验证其表达.CIBERSORT算法探索关键铁死亡基因与免疫细胞浸润的相关性.利用在线数据库和Cytoscape分别预测候选小分子化合物/药物、转录因子和miRNA.结果 筛选出MS中39个为铁死亡基因,与氧化应激相关.确定了 BRD7、MTDH和SMAD7为MS关键铁死亡基因,三者的诊断效能高,在MS小鼠模型中表达均较对照组升高;且与免疫浸润高度相关.结论 MS中铁死亡基因BRD7、MTDH及SMAD7与免疫浸润密切相关.
Transcriptomic Analysis of Ferroptosis-Related Gene and Immune Infiltration in Multiple Sclerosis
Objective To investigate the immune infiltration and integrated network regulation of multiple sclerosis(MS)by transcriptomic analysis.Methods The differentially expressed ferroptosis-related genes of MS was identi-fied and the enrichment analysis was performed by GO and KEGG.LASSO and SVM-RFE algorithms were used to identify key ferroptosis-related genes in MS.ROC curve analysis was generated to test the predictive val-ue of the key ferroptosis-related genes in MS.MS mouse model was constructed to verify their expression by qRT-PCR.The CIBERSORT algorithm explored the correlation of key ferroptosis-related genes and im-mune cell infiltration.Online databases and Cytoscape were applied respectively to predict candidate small mole-cule compounds/drugs,transcription factors and miRNA.Results 39 ferroptosis-related genes of MS were se-lected and they were found associating with oxidative stress.BRD7,MTDH and SMAD7 were identified as the ferroptosis-related genes of MS.These three genes had high diagnostic efficacy and were all increased in the MS mouse model compared with in the control group.Besides,they were highly associated with immune infiltration.Conclusion BRD7,MTDH and SMAD7 were closely related with immune infiltration.
