Abstract: Objective To find the differential expression genes (DEGs) between ameloblastoma and odontogenic keratocyst, analyze their function, and explore the mechanism of ameloblastoma invasion and growth. Methods The gene chip data set GSE38494 was downloaded from GEO database. The LIMMA packets was used to analyze the differential expression genes between ameloblastoma and odontogenic keratocyst. Then the Database for Annotation, Visualization and Integrated Discovery (DIVID) was employed to analyze Gene Oncology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG). The PPI network of differential expression genes was constructed on Search Tool for the Retrieval of Interacting Genes (STRING) website. The results were visualized by Cytoscape software, and the hub genes were screened by MCODE plug-in. Results 335 differential genes were identified. GO analysis showed that differential genes mainly affected neuronal differentiation, cell adhesion, biological adhesion, cell morphogenesis involved in differentiation, cell fate commitment and other biological processes. Cell component enrichment was mainly involved in extracellular domain, extracellular matrix, extracellular region, proteinaceous extracellular matrix, component and synapse of extracellular matrix structure and so on. The molecular function of enrichment was mainly involved in carbohydrate binding, heparin binding and transcription factor activity. KEGG pathway analysis showed that differential genes were mainly engaged in signaling pathways such as ECM-receptor interaction, axon orientation and pathway in cancer. The 8 hub genes were SPARCL1, SERPINA1, ITIH2, IGFBP5, LAMB1, C3, GOLM1 and FAM20A. Conclusion The DEGs between ameloblastoma and odontogenic keratocyst are screened out by means of bioinformatics. The 8 hub genes are expected to become new markers for differential diagnosis between ameloblastoma and odontogenic keratocyst, and provide new ideas for studies on ameloblastoma.
