KLF6 and glioblastoma: Then, we measured the expression of a panel of NF-κB target genes previously implicated in glioblastoma by RT–PCR (Figure 4g and Supplementary Figures 4B and C).32, 33, 34, 35, 36, 37, 38, 39 In all tested cells, the majority of the genes were downregulated upon KLF6-wt overexpression, whereas KLF6-sv1 had no effect.
