GSE (14520, 36376, 57957, 76427) datasets were accessed from GEO database. 55 differential mRNAs (DEGs) were obtained by differential analysis based on the datasets. GO and KEGG analysis results indicated that the DEGs were enriched in xenobiotic metabolic process and other pathways. Expression profiles and clinical data of TCGA-LIHC mRNAs were from TCGA database. We established a prognostic model of HCC through univariate and multivariate Cox risk regression analyses. ROC curve analysis was used to examine the prognostic model performance. GSEA analysis was performed between the high- and low-risk score sample groups.
A 4-gene HCC prognostic model was constructed, in which the gene expressions correlated to HCC patients' survival. The AUC value presented 0.734 in the ROC analysis for the prognostic model.
The four-gene model could be introduced as an independent prognostic factors to assess HCC patients' survival status.
从 GEO 数据库中获取 GSE（14520、36376、57957、76427）数据集。基于数据集进行差异分析，获得 55 个差异表达 mRNA（DEGs）。GO 和 KEGG 分析结果表明，DEGs 富集在外源物代谢过程和其他途径中。TCGA-LIHC mRNAs 的表达谱和临床数据来自 TCGA 数据库。我们通过单因素和多因素 Cox 风险回归分析建立了 HCC 的预后模型。ROC 曲线分析用于检验预后模型的性能。对高风险评分和低风险评分样本组进行 GSEA 分析。
构建了一个与 HCC 患者生存相关的 4 个基因 HCC 预后模型。该预后模型的 ROC 分析 AUC 值为 0.734。
该四基因模型可作为独立的预后因素来评估 HCC 患者的生存状况。
