Expression and signaling of CD30, a tumor necrosis factor (TNF) receptor family member, is upregulated in numerous lymphoid-derived neoplasias, most notably anaplastic large cell lymphoma (ALCL) and Hodgkin’s lymphoma (HL). To gain insight into the mechanism of CD30 signaling, we used an affinity purification strategy that led to the identification of the aryl hydrocarbon receptor nuclear translocator (ARNT) as a CD30 interacting protein that modulated the activity of the RelB subunit of the transcription factor nuclear factor (NF)-κB. ALCL cells deficient in ARNT exhibited defects in RelB recruitment to NF-κB-responsive promoters whereas RelA recruitment to the same sites was potentiated, resulting in augmented expression of these NF-κB-responsive genes. These findings indicate that ARNT functions in concert with RelB in a CD30-induced negative feedback mechanism.
