Gene set variation analysis (GSVA) of differentially activated gene sets identified inhibition of hypoxia, vasculo- and angiogenesis signaling pathways in IDH-1/2 mutant tumors and activation in IDH-1/2 wild-type tumors.
Rows represent samples of 288 patients with low-grade diffuse or anaplastic gliomas from The Cancer Genome Atlas (TCGA). Columns represent GSVA enrichment scores for the individual gene set.
