摘要: 目的 探讨TRIB2在结肠癌中的表达水平及与预后及免疫浸润之间的关系。方法 TIMER数据库分析TRIB2在泛癌种中的表达;TCGA、GSE17538下载结肠癌患者RNA-seq数据和临床信息,评估其与临床病理特征的相关性;生存曲线、单因素和多因素Cox分析探讨TRIB2与预后的相关性,并构建列线图;对TRIB2进行差异基因的富集分析;分析TRIB2表达水平与免疫细胞浸润、免疫检查点、肿瘤突变负荷(TMB)以及免疫治疗敏感性之间的相关性。结果 TRIB2在结肠癌组织中高表达(P<0.05);CMS1结肠癌患者TRIB2 mRNA表达水平最高;TRIB2是结肠癌患者的独立预后因素(单因素Cox回归分析:HR=1.397,95%CI:1.100~1.774,P=0.006;多因素Cox回归分析:HR=1.502,95%CI:1.158~1.947,P=0.002);TRIB2与免疫细胞的浸润密切相关,并且与免疫检查点分子表达水平以及TMB正相关(r=0.39,P<0.001);TRIB2的表达水平与免疫检查点抑制剂的疗效相关。结论 TRIB2在结肠癌中高表达且与结肠癌患者预后差和免疫微环境密切相关。

Abstract: Objective To explore the expression of TRIB2 in colon cancer and its relationship with prognosis and immune cell infiltration. Methods TIMER database was used to analyse the expression of TRIB2 in pan-cancer.RNA-seq data and clinical information of colon cancer patients were downloaded from TCGA and GSE17538 to assess the correlation between TRIB2 with clinicopathological features.Survival curves,univariate and multivariate COX regression analysis were performed to explore the correlation between TRIB2 and prognosis,and a nomogram was constructed.Gene enrichment analyses were performed for TRIB2.Correlations between TRIB2 expression and immune cell infiltration,immune checkpoints,tumor mutation burden(TMB),and immunotherapy sensitivity were analyzed.Results TRIB2 was highly expressed in colon cancer tissues(P<0.05).The highest level of TRIB2 mRNA expression was found in CMS1.TRIB2 was an independent prognostic factor for colon cancer patients(univariate Cox regression analysis:HR=1.397,95%CI:1.100-1.774,P=0.006;multivariate Cox regression analysis:HR=1.502,95%CI:1.158-1.947,P=0.002).TRIB2 was closely associated with immune cell infiltration and positively correlated with the expression level of immune checkpoint molecules as well as TMB(r=0.39,P<0.001).The expression of TRIB2 was correlated with the efficacy of immune checkpoint inhibitors.Conclusions TRIB2 is highly expressed in colon cancer and is closely associated with poor prognosis and the immune microenvironment of colon cancer patients.
