IKKε and TBK1 in diffuse large B-cell lymphoma: A possible mechanism of action of an IKKε/TBK1 inhibitor to repress NF-κB and IL-10 signalling.

ABSTRACT: The IKK-related kinases, IKKε and TBK1, have essential roles in innate immunity in part through modifying MYD88 signalling from the Toll-like receptors to regulate NF-κB signalling. We investigated the expression and function of IKKε and TBK1, in diffuse large B-cell lymphoma (DLBCL). DLBCL cell lines and patient-derived xenografts were used to determine their sensitivity to IKKε and TBK1 inhibitors. To understand the function of IKKε and TBK1 secreted factors were determined following administration of inhibitors. Gene expression microarrays were used to determine the transcriptional effects of inhibitors. Higher TBK1 mRNA levels associated with poorer clinical outcome but IKKε and TBK1 were expressed in both germinal centre and non-germinal centre types of DLBCL. Survival of cell lines L
