Background: Zinc-finger protein 750 (ZNF750) is a potential tumor suppressor in oral squamous cell carcinoma (OSCC). However, the molecular mechanisms underlying its anti-tumor effect remain elusive in OSCC. We report the application of RNA sequencing to identify differentially expressed genes (DEGs) between vector groups and ZNF750 groups (over-expressed ZNF750 in CAL-27 cell), and to elucidate the genes and pathways involved in tumor suppression following the ZNF750 over-expression in OSCC cell line CAL-27 cell. Methods: The RNA sequence libraries were constructed, and the data were analyzed to identify DEGs between vector groups and ZNF750 groups. QPCR and western-blot was used to validate differential expression of candidate genes with cell cycle regulation. The cell cycle distribution was analyzed by BrdU staining. Results: By RNA sequencing profiling, 7,131 genes were differentially expressed in ZNF750 groups. Among the DEGs, 3,285 genes were upregulated, 3,846 genes were downregulated and 4,507 genes were identified in three main categories (cellular_component, biological process and molecular function) based on the gene ontology (GO) classification. The Kyoto Encyclopedia of Genes and Genome (KEGG) pathway analysis defined the DEGs could be categorized into 280 pathways and identified the top two most significant pathways involved in spliceosome and cell cycle. Functional categorization and enrichment analysis revealed that most of DEGs involved in binding and catalytic activity, and the cell cycle associated genes was significantly enriched in response to ZNF750 over-expression. ZNF750 induced cell cycle arrest in G0/G1 phase of the cell cycle. Conclusion: Data from this study revealed that the cell cycle pathway was a key factor involved in the anti-tumor effect of ZNF750 in CAL-27 cells. SOURCE: Haiying Chen Liaocheng People's Hospital
