MDM4 and diffuse large B-cell lymphoma: In addition to the GEP results as above, p63 expression correlated with MDM2 upregulation and BCL2 and MDM4 downregulation (P=0.0174, P=0.0487 and P=0.090 respectively) resembling WT-p53 expression GEP signature (although the FDRs for the comparison between p63+ and p63− DLBCL were higher).
