摘要: 目的: 通过高通量测序筛选口腔扁平苔藓(oral lichen planus, OLP)患者和正常人口腔黏膜组织中差异表达的微小RNA(miRNAs),探讨miRNAs在OLP发病机制中的作用。方法: 收集3例就诊于河北医科大学第四医院口腔科的OLP患者病变组织(P组)和3例正常口腔黏膜组织(N组),进行illumina高通量测序,筛选差异表达的miRNAs,利用生物信息学分析对差异最显著的6个miRNA进行靶基因预测和功能富集分析。结果: 应用DESeq软件,筛选出两组间差异表达的miRNAs共61个(|log2FoldChange| > 1,P<0.05),其中表达上调的23个,下调的38个。选择上调(miR-449c-5p、miR-663b和miR-196a-5p)和下调(miR-133b、miR-1-3p和miR-133a-3p)最显著的miRNA各3个进行靶基因预测,GO分析显示这些靶基因主要富集在细胞膜区域,可能参与了细胞迁移、分化、代谢和分泌调节等生物过程,KEGG分析显示这些靶基因显著富集在MAPK、Rap1、NF-κB、Ras等信号通路上。结论: OLP和正常口腔黏膜之间存在差异表达的miRNA,这些miRNA可通过SEMA3F、HECW1、POLDIP等靶基因作用于MAPK、NF-κB、Rap1等通路,参与OLP的发生发展。

Abstract: Objective: To explore the role of microRNAs (miRNAs) in the pathogenesis of oral lichen planus (OLP). Methods: The tissues of 3 OLP patients (experimental group) and 3 normal individual (control group) were collected in the Department of Stomatology of the Fourth Hospital of Hebei Medical University for illumina high-throughput sequencing to screen the differentially expressed miRNAs. The target genes were predicted and analyzed by bioinformatics analyses. Results: A total of 61 differentially expressed miRNAs were screened between the two groups by using DESeq software, including 23 up-regulated and 38 down-regulated miRNAs. Three of the most significantly up-regulated (miR-449c-5p, miR-663b, and miR-196a-5p) and down-regulated (miR-133b, miR-1-3p, and miR-133a-3p) miRNAs were selected for target gene prediction, and GO analysis revealed that these targets were mainly enriched in the cell membrane region and might be involved in biological processes such as cell migration, differentiation, metabolism, and secretion regulation. KEGG analysis revealed that these targets were significantly enriched in MAPK, Rap1, NF-κB, Ras, and other signaling pathways. Conclusion: There are differentially expressed miRNAs between OLP and normal oral mucosa, and these miRNAs can act on MAPK, NF-κB, Rap1 and other pathways through SEMA3F, HECW1, POLDIP and other target genes to participate in the development and progression of OLP.
