Ravichandran S, Jeyakumar N, Brain tumor biomarker identification by differential gene expression analysis microarray data, Onl J Vet Res., 27 (1): 1-9, 2023. We undertook a meta-analysis to identify drug brain tumor therapeutic targets over-expressed in cancer tissue compared to normal brain tissue. Data mining for differential gene expression analysis of normal and brain cancer tissue by applying sequence odds ratio for significance (P < 0.001). Analyses yielded 2298 up regulated genes in brain tumor tissues and functional annotation through gene ontology database and found 5 enriched GO categories. Analysis of Transcription Factor Activity included 75 genes in KEGG pathway database for 5 genes TCF7L1, RXRA, RXRG, RB1, and NFATC3 implicated in cancer pathways. These genes may be considered as biomarkers for brain tumors.
