Gene Set Enrichment Analysis identified a significant inverse correlation between 'antigen processing and presentation' signature (entry no. hsa04612; KEGG database) and four independent FOXP1 probes in a primary DLBCL microarray data set (n=414; GSE10846: Figure 4b).29 MHC II genes contributing to the core enrichment of the gene set on a negative scale, in all four FOXP1 probes, included HLA-DRA, HLA-DMB, HLA-DQB1, HLA-DPA1, HLA-DPB1 and HLA-DRB1 (Supplementary Table S2). Here, FOXP1 is linked to diffuse large B-cell lymphoma.
