Objective: To construct and analyze the differential expression profiles of microRNAs (miRNA) and mRNA in oral squamous cell carcinoma (OSCC). To explore the miRNA and mRNA of OSCC development and progression.
Methods: The differential expression profiles of miRNA and mRNA were built by high-throughput deep sequencing technology. Using Gene Ontology (GO) enrichment analysis, the roles of differentially expressed miRNA and mRNA in cell cycle, cell proliferation, cell differentiation and cell apoptosis were analyzed.
Results: Seventy-seven differentially expressed miRNA and 1 298 differentially expressed mRNAs were identified in OSCC. GO analysis showed that 73 miRNA had found target mRNA in cell cycle, cell proliferation, cell differentiation and cell apoptosis of OSCC. Moreover, a miRNA could regulate multiple mRNA.
Conclusion: The differential expression profiles of miRNA and mRNA have close relationship with the development and progression of OSCC.
目的: 构建分析口腔鳞状细胞癌（OSCC）中差异表达的微小RNA（miRNA）和mRNA表达谱，初步预测与OSCC发生和发展相关的miRNA和mRNA。
方法: 运用高通量深度测序技术构建miRNA和mRNA表达谱，通过Gene Ontology功能显著性富集分析预测与OSCC细胞周期、增殖、分化和凋亡相关的miRNA和mRNA。
结果: 共发现77个miRNA和1 298个mRNA显著性差异表达，富集分析显示与OSCC细胞周期、增殖、分化和凋亡相关的miRNA共73个，且一个miRNA可调控多个mRNA。
结论: OSCC中差异表达的miRNA和mRNA对OSCC的发生和发展有潜在的作用。
