Abstract: OBJECTIVE: To identify differentially expressed genes in gliomas which were related to their prognosis. METHODS: Raw data of the GEO (Gene Expression Omnibus) database GSE15824 involving normal and glioma tissues were analyzed using R language,and bioinformatics analysis tools (DAVID,String,Cytoscape,oncomine,and GEPIA). Differentially expressed genes were subjected to biological function,protein interaction analysis,and screening for prognostic markers of gliomas. RESULTS: A total of 648 differentially expressed mRNAs, including 471 up-regulated mRNAs and 177 down-regulated mRNAs were screened. Biological functions of these differential genes were mainly enriched in the activation of T cells,and regulation of adhesion of leukocytes and of cell migration. The KEGG signaling pathway was mainly enriched in PI3K/Akt,MAPK,and calcium signaling pathways. Formyl peptide receptor 1 was highly expressed in gliomas,and the expression level was negatively correlated with the prognosis of gliomas (Log-rank P < 0.01). CONCLUSION: Through the analysis of gene expression microarray analysis,FPR1 was highly expressed in gliomas and was related to patients' survival. The observations provide new ideas for further molecular investigations.
