Inhibition of NF-κB Signaling as a Strategy in Disease Therapy
As described extensively in this issue, NF-κB transcription factors regulate a number of important physiological processes, including inflammation and immune responses, cell growth and survival, and the expression of certain viral genes. Moreover, NF-κB activity is elevated in and contributes to the pathology of several human diseases, including many cancers and chronic inflammatory diseases. Therefore, there has been great interest in the characterization and development of methods to limit NF-κB signaling for pharmacological intervention. This article describes some of the approaches that have been employed to inhibit NF-κB using in vitro and in vivo experimental models. Moreover, some examples of the clinical use of NF-κB inhibitors are discussed, primarily for the treatment of two B-cell malignancies, multiple myeloma and diffuse large B-cell lymphoma. Finally, the rationale and strategies for inhibiting specific NF-κB subunit activity for disease therapy are discussed.
