As hepatocellular carcinoma (HCC) is a complex disease, it is hard to classify HCC with a specific biomarker. This study used data from TCGA to create a genetic signature for predicting the prognosis of HCC patients.
In a group of HCC patients ( = 424) from TCGA, mRNA profiling was carried out. To recognize gene sets that differed significantly between HCC and normal tissues, an enrichment study of genes was carried out. Cox relative hazard regression models have been used to identify genes that are significantly associated with overall survival. To test the function of a prognostic risk parameter, the following multivariate Cox regression analysis was used. The log-rank test and Kaplan-Meier survival estimates were used to test the significance of risk parameters for predictive prognoses.
Eight genes have been identified as having a significant link to overall survival (PAM, NUP155, GOT2, KDELR3, PKM, NSDHL, ENO1, and SRD5A3). The 377 HCC patients were divided into eight-gene signature-based high/low-risk subgroups. The eight-gene signature's prognostic ability was unaffected by a number of factors.
To predict the survival of patients with HCC, an eight-gene signature associated with cellular glycolysis was then identified. The findings shed light on cellular glycolysis processes and the diagnosis of patients with low HCC prognoses.
由于肝细胞癌(HCC)是一种复杂疾病,很难用特定生物标志物对其进行分类。本研究利用来自癌症基因组图谱(TCGA)的数据创建了一个基因特征,用于预测HCC患者的预后。
在一组来自TCGA的HCC患者(n = 424)中进行了mRNA谱分析。为了识别HCC与正常组织之间存在显著差异的基因集,对基因进行了富集研究。采用Cox相对风险回归模型来识别与总生存期显著相关的基因。为了检验预后风险参数的功能,采用了以下多变量Cox回归分析。采用对数秩检验和Kaplan-Meier生存估计来检验风险参数对预测预后的显著性。
已确定八个基因与总生存期有显著关联(PAM、NUP155、GOT2、KDELR3、PKM、NSDHL、ENO1和SRD5A3)。这377例HCC患者被分为基于八基因特征的高/低风险亚组。八基因特征的预后能力不受多种因素影响。
为了预测HCC患者的生存期,随后确定了一个与细胞糖酵解相关的八基因特征。这些发现揭示了细胞糖酵解过程以及低HCC预后患者的诊断情况。
