Abstract:

目的:通过GEO公共数据库,探讨ATP柠檬酸盐裂合酶(ACLY)在多种肿瘤中的表达情况,并进一步探索其与肝细胞癌临床病理特征的关系,评价ACLY对肝细胞癌术后患者预后评价的意义,预测ACLY推动肝细胞癌发展的机制。方法:收集NCBI的肿瘤公共数据集,对表达谱资料及临床信息进行分析;利用基因富集分析(GSEA)方法,分析受ACLY调控的相关基因。结果:ACLY在多种肿瘤中高表达(P<0.05);在不同年龄、AFP、肿瘤大小、T分期、BCLC分期的肝细胞癌患者中,ACLY的表达均有显著性差异(P<0.05);ACLY的表达状态与肝细胞癌患者术后的总体生存和复发相关(P<0.05);ACLY高表达样本富集了与有丝分裂、细胞周期调控、血管生成、E2F1信号通路、myc信号通路相关的基因集。结论:ACLY在多种肿瘤中高表达,且可以作为潜在的判断肿瘤患者预后的标志物和治疗肿瘤的靶标
