Summary:Oral cancer is one of the most common cancers in the world, meanwhile, differentially expressed genes are thought to regulate the development and progression of oral squamous cell carcinomas (OSCC). In this study we screened RNA transcripts from the oral buccal mucosa of healthy male Chinese hamster, divided into 3 groups: a control group with no disposal, a solvent control group coated with acetone solvent, and an experimental group coated with 0.5% DMBA acetone solution by high-throughput RNA sequencing. Tophat and Bowtie were used to align the high-quality reads into transcripts, DEseq was used to analysis the expression of differential gene. Then, the Gene Ontology (GO) enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were conducted. The chemokine and TNF signaling pathway were differentially expression and the mRNA expression of CXCL1, CXCL2, CXCL3, CCL7, MMP9, monitored by qRT-PCR, increased remarkably in the cancer group and coincided with the result of RNA-Sequencing. Meanwhile, the CXCL1, CXCL2, CXCL3, and CCL7 are significantly enriched in the chemokine signaling pathway, and CXCL1, CXCL2, CXCL3, and MMP9 are significantly enriched in the tumor necrosis factor (TNF) signaling pathway. The differentially expression of the chemokine and TNF signaling pathway was a response to the invasion of the organism immune system due to oral buccal mucosa squamous carcinoma. All the findings provided novel insights for further molecular researches of oral cancer.
