FOXP1 and diffuse large B-cell lymphoma: To identify FOXP1-regulated biological processes in GCB- and ABC-DLCBL cell lines, we applied GO enrichment analysis to FOXP1-repressed or FOXP1-induced gene sets with a fold change cutoff of ±1.41 (corresponding to ±0.5 on log2 scale), comparable to other studies.38 Genes commonly regulated by FOXP1 in GCB- or ABC-DLBCL cells were derived from several distinct biological processes (Figure 2).
