In the present study, the cytoplasmic and perinuclear expression levels of CYLD suggest that CYLD may play a role in the deubiquitination of BCl-3 and/or TRAF in NF-κB signaling within the cytoplasm or perinuclear region in keratinocytes of normal skin and cholesteatoma, in agreement with previously reported results. Here, NFKB1 is linked to cholesteatoma.
