To elucidate the biological processes, molecular function, cellular component and pathway associations of ALKBH5 in GBMs, we conducted gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis in GBM by categorizing GBMs into ALKBH5-low and ALKBH5-high two subgroups. Here, ALKBH5 is linked to glioblastoma.
