RELA and diffuse large B-cell lymphoma: Collectively, our work showed effects of inhibitors on RELA phosphorylation and gene expression, which supports a role for IKKε/TBK1 in contributing to NF‐κB activity in some DLBCL and we note that Ly10, which was used for the gene expression studies has constitutive NF‐κB activity due to MYD88 mutation.
