NFκB index and regulators of NFκB activity. (A) NFκB index determined by Annunziata et al31 on the basis of the mean expression of 11 genes (BIRC3, TNFAIP3, NFKB2, IL2RG, NFKBIE, RELB, NFKBIA, CD74, PLEK, MALT1, WNT10A). (B) NFκB index determined by Keats et al32 on the basis of the mean expression of 4 genes (CD74, IL2RG, and TNFAIP3, 2×). Expression (log2) per cluster of negative regulators of the NFκB pathway: (C) TRAF3 and (D) CYLD. Expression (log2) of positive regulators of NFκB pathway: (E) CD40 and (F) NIK.
