摘　　要：目的利用GEPIA数据库,包括TCGA数据库和GTEX数据库,探讨二氢丹参酮Ⅰ通过氧化应激治疗胃癌的潜在靶点。方法在数据库中检索二氢丹参酮Ⅰ在胃癌中潜在靶点的文献,利用GEPIA数据库工具分析二氢丹参酮Ⅰ在胃癌中的潜在作用机制,分析潜在靶基因与表达关键抗氧化应激蛋白基因的相关性;二氢丹参酮Ⅰ对胃癌潜在靶基因表达水平的分析;二氢丹参酮Ⅰ对胃癌潜在靶基因的预后分析。结果二氢丹参酮Ⅰ对潜在靶基因的主要靶向基因(蛋白)为缺氧诱导因子-1 (hif-1)和瓜氨酸组蛋白h3 (cith3),其基因分别为HIF1 A和NOS2;GEPIA数据库显示HIF1 A与CAT (P=e-04,r=0. 18)、GPX1 (P=0. 033,r=0. 11)或NFE2L2呈正相关。(P=0,r=0. 41),而NOS2与SOD1仅呈正相关(P=0. 21,r=0. 18),与其它三个基因均无相关性;HIF1 A和NOS2在胃癌组织中的表达水平高于正常胃旁组织;HIF1 A的高表达降低了胃癌患者的总生存率。结论二氢丹参酮Ⅰ可通过活性氧介导的氧化应激诱导AGS细胞凋亡,抑制HIF1 A和NOS2的表达,从而抑制AGS细胞的抗氧化应激,提高胃癌患者的总生存率。Objective In this study,GEPIA database,including TCGA database and GTEx database,were used to explore the potential targets of dihydrotanshinone Ⅰ on gastric cancer through oxidative stress. Methods Literatures on potential targets of dihydrotanshinone Ⅰ in gastric cancer were searched in the database;GEPIA database tool was used to analyze the potential mechanism of dihydrotanshinone Ⅰ on gastric cancer;taking analysis of the correlation between potential target genes and genes expressing key antioxidant stress proteins;We had analysis of expression level of dihydrotanshinone Ⅰ on potential target genes in gastric cancer patients;and prognostic analysis of dihydrotanshinone Ⅰ on potential target genes in gastric cancer patients. Results The main targeting genes( proteins) of dihydrotanshinone Ⅰ on potential target genes were hypoxia inducible factor-1( hif-1) and citrulline histone H3( CITH3),whose genes were HIF1 A and NOS2,respectively;GEPIA database showed that there was a positive correlation between HIF1 A and CAT( P = 2 e-04,R = 0. 18),GPX1( P = 0. 033,R = 0. 11),or NFE2 L2( P = 0,R = 0. 41),while NOS2 only had a positive correlation with SOD1( P =0. 21,R = 0. 18),and no correlation with other three genes. The expression levels of HIF1 A and NOS2 in gastric cancer tissues were higher than those in normal adjacent gastric tissues. The overall survival rate of patients with gastric cancer decreased with the high expression of HIF1 A. Conclusion Dihydrotanshinone Ⅰ may induce apoptosis of AGS cells through reactive oxygen species mediated oxidative stress,and inhibit the expression of HIF1 A and NOS2,thus inhibit their antioxidative stress,which may improve the overall survival rate of gastric cancer patients.
