摘　　要：背景:蒜氨酸作为大蒜中的主要活性成分具有抗炎和抗氧化作用,但蒜氨酸改善类风湿性关节炎的作用和机制仍不清楚。目的:利用基因表达数据分析类风湿性关节炎的差异表达基因,探讨蒜氨酸在类风湿性关节炎中的调控作用。方法:从GSE45291和GSE93777数据集中收集类风湿性关节炎的基因表达数据,进行差异表达分析。对两套数据中的共同差异表达基因进行共表达网络分析,识别与类风湿性关节炎相关性最高的模块基因,进行功能富集分析。通过SwissTargetPrediction数据库预测蒜氨酸的靶向调控基因,并与差异表达基因行交集分析,计算差异表达靶基因的受试者工作特征曲线下面积。将人永生化类风湿性关节炎滑膜成纤维细胞接种于孔板内培养24 h后分5组处理:对照组不进行任何处理,阳性药组加入甲氨蝶呤,蒜氨酸低、中、高质量浓度组分别加入20,80,160μg/mL的蒜氨酸,处理48 h后,CCK-8法检测细胞活性,TUNEL法检测细胞凋亡,ELISA法检测氧化应激和炎症因子水平,JC-1法检测线粒体膜电位变化,RT-qPCR和Western Blot检测靶基因及相关信号通路的表达。结果与结论:(1)在GSE45291和GSE93777数据集中共鉴定出6 487个共同的差异表达基因,并获得了12个共表达模块,magenta模块与类风湿性关节炎的相关性最高,模块基因主要富集于磷酯酰肌醇3-激酶/蛋白激酶B(PI3K/AKT)信号通路。(2)通过数据库预测发现7个差异表达基因被蒜氨酸靶向调控,其中表皮生长因子受体在GSE45291数据集中的受试者工作特征曲线下面积值最大,犬尿氨酸酶在GSE93777数据集中的受试者工作特征曲线下面积值最大。(3)与对照组比较,其他4组类风湿性关节炎滑膜成纤维细胞活性降低,细胞凋亡数量增加,活性氧、丙二醛、白细胞介素6、白细胞介素1β水平均降低,线粒体膜电位均升高,表皮生长因子受体、犬尿氨酸酶、线粒体动力�BACKGROUND:Allicin,the main active ingredient in garlic,has anti-inflammatory and antioxidant effects,but the role and mechanism of allicin in ameliorating rheumatoid arthritis remain unclear.OBJECTIVE:To analyze differentially expressed genes in rheumatoid arthritis using gene expression data and explore the regulatory role of alliin in rheumatoid arthritis.METHODS:Gene expression data for rheumatoid arthritis were collected from the GSE45291 and GSE93777 datasets,and differential expression analysis was then performed.Co-expression network analysis was conducted on the common differentially expressed genes identified in both datasets to identify the module genes most closely related to rheumatoid arthritis,followed by functional enrichment analysis.The SwissTargetPrediction database was used to predict the target genes of allicin in the differentially expressed genes.The area under the receiver operator characteristic curve(AUC)of the differentially expressed target genes was calculated.Human immortalized rheumatoid arthritis fibroblast-like synoviocytes were seeded onto pore plates and cultured for 24 hours,and the cells were then divided into five groups.The control group was not treated;methotrexate was added to the positive drug group;and 20,80,and 160μg/mL allicin was added to the low-,medium-,and high-dose allicin groups,respectively.After 48 hours of treatment,cell activity was assessed using cell counting kit-8 assay and cell apoptosis was detected using TUNEL assay.Levels of oxidative stress and inflammatory factors were measured by ELISA.Changes in mitochondrial membrane potential were detected by JC-1 staining.The expression levels of target genes and related signaling pathways were detected by RT-qPCR and western blot.RESULTS AND CONCLUSION:A total of 6487 common differentially expressed genes were identified in the GSE45291 and GSE93777 datasets,and 12 co-expression modules were obtained.The magenta module had the highest correlation with rheumatoid arthritis,with module genes primarily enriched i
