Differential expression of NFκB target genes in large B-cell lymphoma subtypes. NFκB target genes that met the 99th percentile of the permutation distribution and exhibited a 30% or more difference in median expression values were considered to be differentially expressed. Differentially expressed NFκB target genes in (A) primary MLBCL versus DLBCL; (B) ABC-like DLBCLs versus GCB-like and other DLBCLs; and (C) HR DLBCLs versus OxPhos and BCR/proliferation DLBCLs. (D) Comparison of the NFκB target gene signatures from primary MLBCL, HR DLBCLs, and ABC-like DLBCLs.
