NFKB1 and ependymoma: By contrast, only 1.1 and 4.4% of these NF-κB target genes were identified in the RELAFUS1 target genes in 293T-RELAFUS1 and H1203 cells, respectively, highlighting the importance of yet unknown- or non-NF-κB target genes in the RELAFUS-driven ependymoma formation (Additional file 3: Fig. S2H, I).
