Differential expression of NFκB target genes in an independent series of primary MLBCLs and DLBCLs. The independent data set includes all primary MLBCLs (38 tumors) and DLBCLs (26 tumors: 13 GC-type and 13 ABC-like) that were made available at the NIH Lymphoma/Leukemia Molecular Profiling Project website.27 Differentially expressed NFκB target genes were defined as in Figure 3. (A) MLBCLs versus DLBCLs. This independent series of primary MLBCLs had significantly higher expression of 79% (26/33) of the NFκB target genes that were identified in our series and represented on both platforms; and (B) GC-type versus ABC-like DLBCLs.
