NFĸB family members, RELA and REL, are highly expressed in MS Clusters 1 and 0, respectively, while expression of NFĸB target genes and enrichment of NFĸB-associated gene signatures were found in MS Clusters 1 and 3 (Fig. 4D, E and Additional file 2: S. Table 8). This evidence concerns the gene RELA and myeloid sarcoma.
