摘要

摘要: 目的通过探讨差异性表达的外泌体lncRNA及其调控的信号通路在结直肠癌发生、发展中的作用，以期为结直肠癌的诊断和治疗提供新的靶点。方法使用R软件线性回归模型软件包limma包进行差异表达分析，根据筛选阈值得到显著差异表达的lncRNA和mRNA；通过计算差异表达lncRNA与mRNA皮尔逊相关性系数，获得其之间协同表达关系，通过相关系数筛选存在正向协同表达的lncRNA-mRNA关系对；分别对lncRNA的协同表达mRNA进行GO功能和KEGG通路富集分析，以间接预测lncRNA的功能。结果在32例健康志愿者和12例结直肠癌患者中筛选出差异性表达的外泌体lncRNA共202个、mRNA共1 014个。验证出差异性表达的lncRNA-mRNA关系对10个。对lncRNA协同表达的mRNA进行功能富集显示，差异性表达的外泌体lncRNA可能与B细胞受体信号通路、NF-κB信号通路、JAK-STAT信号通路、抗原处理与呈递信号通路和NOD样受体信号通路活化密切相关。结论深入探索外泌体lncRNA在结直肠癌中的差异性表达、功能富集及通路活化，有助于为结直肠癌的治疗提供新思路，为诊断提供新靶点。

Abstract: Objective To explore the role of differential expression of exosome lncRNA and its regulated signal pathway in the occurrence and development of colorectal cancer and provide a new target for the diagnosis and treatment of colorectal cancer. Methods The linear regression model package limma of R software was used to analyse the differential expression of lncRNA and mRNA. By calculating the Pearson correlation coefficient between differentially expressed lncRNA and mRNA, their co-expression was obtained. The positive co-expression of lncRNA-mRNA was screened by using a correlation coefficient. Go function and KEGG pathway enrichment of mRNA co-expressed with lncRNA were analysed to indirectly predict the function of lncRNA. Results A total of 202 differentially expressed exosome lncRNAs and 1014 exosome mRNA were screened from 32 healthy volunteers and 12 colorectal cancer patients. Ten pairs of lncRNA-mRNA co-expression were verified. Functional enrichment of mRNA co-expressed by lncRNA showed that differentially expressed exosome lncRNA may be closely related to B cell receptor signal pathway, NF-KB signal pathway, JAK-STAT signal pathway, antigen processing and presentation signal pathway and NOD-like receptor signal pathway activation. Conclusion In-depth exploration of differential expression, functional enrichment and pathway activation of exosome lncRNA in colorectal cancer is important to provide new ideas for the diagnosis and treatment of colorectal cancer.
