The set of genes identified as GFAP-regulated low-malignant genes, also contained 4 genes which showed the GFAP-dependent pattern within one or more of the astrocytoma grades (NOS2, SPC24, VAV3, and DUSP4; Figure 6A-6H, corresponding statistics in Supplementary Table 9). This evidence concerns the gene DUSP4 and astrocytoma (excluding glioblastoma).
