Figure 4 shows the top 10 functional categories identified, mainly involving biological processes such as oxidative stress, cell proliferation, cell cycle, cell invasion, and migration. A total of 114 signaling pathways were obtained through the undertaken KEGG enrichment analysis (Supplementary 7). The top 5 signaling pathways were the MAPK signaling pathway, the PI3K-AKT signaling pathway, the RAS signaling pathway, and the cell cycle, and the glioma signaling pathway (Table 2). This evidence concerns the gene AKT1 and central nervous system cancer.
