title: IKK- and NF-κB-mediated functions in carcinogenesis.
abstract: Since the initial cloning of RelA and its close relationship to c-Rel, the cellular homolog of the viral oncoprotein v-Rel, the nuclear factor κB (NF-κB) signaling pathway and its upstream activating kinase complex (IκB-kinase) have been suspected to play a major role in tumorigenesis. This was further corroborated by the discovery of oncogenic mutations in NF-κB proteins in certain lymphoid malignancies and the notion that NF-κB is persistently activated in a large variety of solid tumors. With the advent of conditional knockout mice allowing tissue-specific targeting of the various components of the NF-κB signaling pathway, it was possible to genetically test the cell autonomous and non-autonomous functions of NF-κB in inflammation-associated cancer as well as sporadic cancers. Here, we review molecular evidence that demonstrates the various functions of NF-κB during different tumor stages and that supports the rationale to target NF-κB in cancer prevention and therapy.
