摘要
目的分析hsa-mir-337表达在判断乳腺癌病人预后的作用。方法利用人类肿瘤基因组(TCGA)数据库下载乳腺癌miRNA测序数据及其对应的临床病理资料,使用R软件进行数据分析。Cox单因素回归分析与不良预后相关的miRNAs,对差异表达中有意义的miRNAs进行Cox多因素回归分析,建立风险评估模型,使用基因富集方法(GSEA)预测hsa-mir-337的调控基因。结果hsa-mir-337低表达病人的总生存期低于高表达。Cox比例风险模型的多变量分析表明hsa-mir-337(HR=0.981062,P<0.001)可以作为乳腺癌的独立预后因素。结论hsa-mir-337可成为预测乳腺癌预后的有效生物标志物。
Objective To identify the prognostic role of hsa-mir-337 in breast cancer.Methods The TGGA database was used to gain miRNA-seq expression as well as clinical data.R software was used for data analysis.Univariate Cox analysis as well as Multivariate Cox analysis were used to identify the prognostic significance of hsa-mir-337 in BREAST CANCER patients.GSEA was performed to analyze the functional annotation of the predicted genes.Results Hsa-mir-337 was significantly associated with overall survival(OS)of BREAST CANCER.The low expression group had worse OS compared to the high expression group.Through Multivarite analysis with Cox proportional hazards model indicated that hsa-mir-337(HR=0.981062,P<0.001)was independent progonostic factor for patients with breast cancer.Conclusion Hsa-mir-337 was identified as an independent factor in the prognosis of breast cancer.
