We thus analyzed the Immune Escape Gene Signature published by C Laurent et al (Additional file 1: Table S1) [7] from the Affymetrix transcriptome (HT MG-430 PM Array, Additional file 1: Table S2 and Additional file 2: Table S3) of a series of six LMP1/CD40 B-cell lymphomas that were compared to their CD19_Cre littermate. This evidence concerns the gene PDLIM7 and B-cell non-Hodgkin lymphoma.
