AKR1C3 and astrocytoma (excluding glioblastoma): We found that 4 of the genes that we identified as GFAP-regulated high-malignant genes: i.e. NTRK2, FBXO2, ST3GAL6, and AKR1C3, also correlated with GFAPα or GFAPδ/α ratio within an astrocytoma grade (Figure 5A-5H, corresponding statistics in Supplementary Table 9).
