目的 探讨基于糖酵解相关基因预测弥漫大B细胞淋巴瘤(DLBCL)的肿瘤免疫微环境,并研究其潜在机制.方法 从NCICCR数据库中下载DLBCL患者的RNA-seq数据和相应的临床信息,基于糖酵解相关基因,采用共识聚类的方法将其分为C1簇和C2簇.采用Kaplan-Meier(K-M)生存分析、ESTIMATE、TIMER和ssGSEA分析来确定所识别的2个簇类之间的生存、功能和肿瘤微环境(TME)的差异性.通过GO、KEGG和GSEA功能分析阐明其潜在机制.结果 2个簇类之间的生存率显著不同;K-M生存曲线表明,C1簇的存活率高于C2簇,并且免疫评分、ESTIMATE评分与基质评分高于C2簇.GO和KEGG分析表明,两簇之间的差异性表达基因主要在细胞外基质和免疫途径中富集.GSEA分析显示,免疫通路在C1簇的富集度高于C2簇.结论 差异性表达基因于C1簇中与肿瘤免疫微环境显著相关,并且生存率高于C2簇.说明糖酵解代谢失调导致了肿瘤免疫微环境的损害,从而导致DLBCL预后不良.
Effect of Glycolysis-related Genes on the Immune Microenvironment of DLBCL Based on Bioinformatics Analysis
Objective To explore the prediction of tumor immune microenvironment in diffuse large B-cell lymphoma(DLBCL)based on glycolysis-related genes,and to study its potential mechanism.Methods The RNA-seq data and corresponding clinical information of DLBCL patients were downloaded from the NCICCR database.Based on the genes related to glycolysis,they were divided into C1 cluster and C2 cluster by consensus clustering method.Kaplan-Meier(K-M)survival analysis,ESTIMATE,TIMER,and ssGSEA analysis were used to determine differences in survival,function,and tumor microenvironment(TME)between the two identified cluster classes.The potential mechanism was elucidated by GO,KEGG and GSEA functional analysis.Results The survival rates between the two clusters were significantly different.The K-M survival curve showed that the survival rate of C1 cluster was higher than that of C2 cluster,and the immune score,ESTIMATE score and matrix score were higher than those of C2 cluster.GO and KEGG analysis showed that the differentially expressed genes between the two clusters were mainly enriched in extracellular matrix and immune pathways.GSEA analysis showed that the enrichment of immune pathways in C1 cluster was higher than that in C2 cluster.Conclusion Differentially expressed genes in C1 cluster are significantly associated with tumor immune microenvironment,and the survival rate is higher than that in C2 cluster.It indicates that the disorder of glycolysis metabolism leads to the damage of tumor immune microenvironment,which leads to the poor prognosis of DLBCL.
