Analysis of the expression of other mesenchymal gene candidates such as NF110, CREB134, and ZEB126, 35–37 across GBM subtypes revealed that NF1 and ZEB1 expression were rather significantly reduced in mesenchymal versus other GBM subtypes, whereas CREB1 expression was similar across GBM subclasses (Fig. 2D–F). This evidence concerns the gene NF1 and glioblastoma.
