    摘要:

    目的 分别构建由自噬相关基因(ATG)与自噬相关lncRNA(ATL)构成的预后模型,预测胶质母细胞瘤(GBM)患者的预后情况,为其个性化诊疗与基础研究提供依据。方法 利用TCGA数据库中GBM的测序与临床数据,通过单因素Cox回归分析筛选差异表达且具备预后价值的ATG与ATL,之后通过多因素Cox回归分析分别构建预后模型,根据模型计算患者风险值并验证其有效性。结果 GBM组织相较正常组织共筛选到72个差异表达的ATG(上调53个,下调19个)和170个ATL(上调102个;下调68个),单因素Cox回归分析筛选到16个与患者预后相关的ATG和22个ATL,多因素Cox回归分析分别纳入3个ATG与8个ATL构建预后模型。生存曲线显示在2个模型中高风险组生存率远低于低风险组,受试者工作特性曲线证明2个模型均具有较好的预测能力。结论 所构建的2个预后模型可有效预测患者生存情况,并提供个性化诊疗与基础研究参考。

    Abstract:

    Objective Two prognostic models consisting of autophagy-related gene (ATG) or autophagy-related lncRNA (ATL) were constructed to predict the prognosis of patients with glioblastoma multiforme (GBM) and provide the basis for personalized diagnosis and treatment.Methods The RNA sequencing and clinical data of GBM in TCGA database were used to screen the differentially expressed ATG and ATL with prognostic value by univariate Cox regression analysis. Then, the prognostic models were constructed by multivariate Cox regression analysis, the risk values of patients were calculated according to the models and their effectiveness was verified.Results Compared with normal tissues, 72 differentially expressed ATG (up-regulated 53, down-regulated 19) and 170 differentially expressed ATL (up-regulated 102; down-regulated 68) were obtained. 16 ATG and 22 ATL were identified by univariate Cox regression analysis and multivariate Cox regression analysis included 3 ATG and 8 ATL, respectively, to construct the prognosis model. The survival curves of the two models showed that the survival rate of the high-risk group was much lower than that of the low-risk group, and the receiver operating characteristic curves proved that both models had good predictive ability.Conclusions The two prognostic models can effectively predict the survival of GBM patients, and provide reference for personalized diagnosis and treatment.
