title: Integrated Analysis and MicroRNA Expression Profiling Identified Seven miRNAs Associated With Progression of Oral Squamous Cell Carcinoma.
abstract: MicroRNAs have been used as diagnostic and prognostic biomarkers for many cancers including oral squamous cell carcinoma (OSCC). Several studies have been shown that microRNA (miRNA) play important roles during the progression of OSCC. However, the results vary largely in different studies due to different platforms and sample sizes. In this study, we systematically evaluated a large scale of miRNA profiles from current qualified OSCC samples, and further investigated the functions of genes regulated by these key miRNAs as well as the signaling pathways through which these miRNA effect carcinogenesis. Seven key miRNAs were identified, and of which three were significantly upregulated, including hsa-miR-21, hsa-miR-31, hsa-miR-338, and four were downregulated, namely hsa-miR-125b, hsa-miR-133a, hsa-miR-133b, and hsa-miR-139. The function enrichment analysis revealed that target genes of upregulated miRNAs were associated with cellular protein metabolic process, macromolecule metabolic process, and TGF-beta pathway, while the targets of downregulated were enriched in negative regulation of macromolecule biosynthetic process and gene expression, and p53, long-term potentiation and adherens junction pathways. Transcription factor analysis revealed that there were 67 (51.1%) transcription factors influenced by both up and downregulated miRNAs. In summary, seven key miRNAs were found to play essential role in progression of OSCC, as well as the target genes and transcription factors of these miRNAs. The potential functions of these target genes identified in our study may be profitable to diagnosis and prognostic prediction of OSCC as biomarkers. J. Cell.
