摘要: 目的 研究细胞坏死相关基因对肝细胞癌(HCC)患者预后的影响。方法 自癌症基因组图谱TCGA数据库下载HCC患者mRNA水平数据及其对应的临床资料。应用LASSO Cox回归在TCGA文件中构建多坏死相关基因预后模型。结果 在单因素Cox回归分析中,23个细胞坏死相关差异水平基因与预后生存相关(P<0.05);构建一个显著相关的6个细胞坏死相关基因的预后模型,发生高风险组总体生存期显著低于低风险组(P<0.01);多因素Cox回归分析风险评分符合独立的预后因子标准(P<0.O1);对差异水平基因进行富集分析(GO/KEGG)和单样本基因集富集分析(ssGSEA),发现差异基因与免疫通路显著相关(P<0.05)。结论 通过6个细胞坏死相关基因构建的预后模型可以用于预测HCC患者的预后,或许能为HCC患者的临床治疗提供参考。

Abstract: Objective The purpose of this study was to investigate the impact of cell necrosis-related genes on prognosis of patients with hepatocellular carcinoma (HCC). Methods The mRNA data of patients with HCC and the clinical data of corresponding patients were downloaded from the Cancer Genome Atlas TCGA database. The polynecrosis-related gene prognostic models were constructed in TCGA files by using LASSO Cox regression. Results by univariate Cox regression analysis, 23 cell necrosis-related differentially expressed genes were associated with prognostic survival (P < 0.05); in this protocol, a significantly correlated prognostic model of 6 cell necrosis-related genes was constructed; the patients were divided into two groups according to the threshold of risk, and the overall survival in patients with high risk was significantly reduced as compared to in those with low risk (P<0.01); meanwhile, by multivariate Cox regression analysis, the risk score met the criteria for independent prognostic factors (P<0.01); the enrichment analysis (GO/KEGG) and one-sample gene set enrichment analysis (ssGSEA) were performed based on differentially gene levels, and the differential genes were found to be correlated to immune pathways (P<0.05). Conclusion The prognostic model we constructed by 6 cell necrosis-related genes could be applied to predict independently the prognosis of patients with HCC and provide a reference for the clinical management appropriately.
