TP53 and diffuse large B-cell lymphoma: GEP analysis of cases with PIM1mutant versus PIM1WT in HGBCL, NOS, ABC‐DLBCL, and GCB‐DLBCL were compared, and the consensus of upregulated genes showed enrichment of genes related to MYC and NF‐κB‐related pathways, whereas downregulated pathways included genes involved in KRAS signaling and the p53 responses (Figure S3).
