Abstract

Colon cancer is one of the most common malignant tumors of the digestive system that seriously threaten human health and whose pathogenesis has not been completely elucidated. The purpose of this study was to investigate genes related to colon cancer and explore their potential values in colon cancer prognosis. Clinical information and transcriptome data of patients with colon cancer were obtained from UCSC Xena. The differentially expressed genes (DEGs) between colon cancer tissues and normal colon tissues were identified and analyzed by R packages. A total of 1414 DEGs were identified, including 593 upregulated and 821 downregulated genes in colon cancer tissues. These DEGs were enriched in multiple biological processes, such as cell junction organization, mitotic nuclear division and digestive tract development. The expression of 14 DEGs (such as PBK, C2CD4A and CXCL10) was correlated with tumor stages of colon cancer. Kaplan-Meier survival analysis showed that the expression of 139 DEGs (such as HSPA1A, CCDC136 and SEZ6L2) was related to the prognosis of patients with colon cancer. The prognosis prediction model constructed based on 35 DEGs could effectively estimate 3- and 5-year overall survival (OS) of patients with colon cancer (AUC of 3- and 5-year OS were 0.816 and 0.897, respectively). In addition, the OS of high-risk patients was significantly poorer than that of low-risk patients. In conclusion, the present study identified multiple genes related to the development and prognosis of colon cancer, which would provide novel molecular targets for the diagnosis and therapy of colon cancer.

基于转录组鉴定与结肠癌发展和预后相关的分子标志物

摘要

结肠癌是消化系统最常见的恶性肿瘤之一,严重威胁人类健康,其发病机制尚未完全阐明。本研究的目的是研究与结肠癌相关的基因,并探讨它们在结肠癌预后中的潜在价值。结肠癌患者的临床信息和转录组数据来自 UCSC Xena。通过R包对结肠癌组织和正常结肠组织之间的差异表达基因(DEGs)进行鉴定和分析。共鉴定出1414个DEGs,包括结肠癌组织中593个上调基因和821个下调基因。这些DEGs在多种生物过程中富集,如细胞连接组织、有丝分裂核分裂和消化道发育。14个DEGs(如PBK、C2CD4A和CXCL10)的表达与结肠癌的肿瘤分期相关。Kaplan-Meier生存分析显示139个DEGs(如HSPA1A、CCDC136和SEZ6L2)的表达与结肠癌患者的预后相关。基于35DEGs构建的预后预测模型可以有效估计结肠癌患者的3年和5年总生存期(OS)(3年和5年OS的AUC分别为0.816和0.897)。此外,高危患者的OS明显低于低危患者。总之,本研究鉴定了多个与结肠癌发生发展和预后相关的基因,为结肠癌的诊断和治疗提供了新的分子靶点。C2CD4A 和 CXCL10) 与结肠癌的肿瘤分期相关。Kaplan-Meier生存分析显示139个DEGs(如HSPA1A、CCDC136和SEZ6L2)的表达与结肠癌患者的预后相关。基于35DEGs构建的预后预测模型可以有效估计结肠癌患者的3年和5年总生存期(OS)(3年和5年OS的AUC分别为0.816和0.897)。此外,高危患者的OS明显低于低危患者。总之,本研究鉴定了多个与结肠癌发生发展和预后相关的基因,为结肠癌的诊断和治疗提供了新的分子靶点。C2CD4A 和 CXCL10) 与结肠癌的肿瘤分期相关。Kaplan-Meier生存分析显示139个DEGs(如HSPA1A、CCDC136和SEZ6L2)的表达与结肠癌患者的预后相关。基于35DEGs构建的预后预测模型可以有效估计结肠癌患者的3年和5年总生存期(OS)(3年和5年OS的AUC分别为0.816和0.897)。此外,高危患者的OS明显低于低危患者。总之,本研究鉴定了多个与结肠癌发生发展和预后相关的基因,为结肠癌的诊断和治疗提供了新的分子靶点。CCDC136和SEZ6L2)与结肠癌患者的预后有关。基于35DEGs构建的预后预测模型可以有效估计结肠癌患者的3年和5年总生存期(OS)(3年和5年OS的AUC分别为0.816和0.897)。此外,高危患者的OS明显低于低危患者。总之,本研究鉴定了多个与结肠癌发生发展和预后相关的基因,为结肠癌的诊断和治疗提供了新的分子靶点。CCDC136和SEZ6L2)与结肠癌患者的预后有关。基于35DEGs构建的预后预测模型可以有效估计结肠癌患者的3年和5年总生存期(OS)(3年和5年OS的AUC分别为0.816和0.897)。此外,高危患者的OS明显低于低危患者。总之,本研究鉴定了多个与结肠癌发生发展和预后相关的基因,为结肠癌的诊断和治疗提供了新的分子靶点。基于35 DEGs构建的预后预测模型可以有效估计结肠癌患者的3年和5年总生存期(OS)(3年和5年OS的AUC分别为0.816和0.897)。此外,高危患者的OS明显低于低危患者。总之,本研究鉴定了多个与结肠癌发生发展和预后相关的基因,为结肠癌的诊断和治疗提供了新的分子靶点。基于35DEGs构建的预后预测模型可以有效估计结肠癌患者的3年和5年总生存期(OS)(3年和5年OS的AUC分别为0.816和0.897)。此外,高危患者的OS明显低于低危患者。总之,本研究鉴定了多个与结肠癌发生发展和预后相关的基因,为结肠癌的诊断和治疗提供了新的分子靶点。
