Gene Ontology analysis reveals activation of distinct pathways in diverse anatomic features of glioblastoma: Function of top-20 (a–f) and 29 outcome predictive gens (g–i) represented as Gene Ontology tree in indicated categories. Color bars (a,b,d,e) represent an enrichment of upregulated genes from different anatomic tumor features (LE-pink, CT-green, PZ-blue), a single-color square indicates activation of unique pathways, and a two-color square indicates shared pathways. FDR values are shown as a heat map, with red maxim and blue minimum.
