- Immunohistochemical analysis of paraffin-embedded HCT 116 cell pellets, untreated (left) or treated with Human Tumor Necrosis Factor-α (hTNF-α) #8902 (right), using NF-κB p65 (D14E12) XP® Rabbit mAb #8242. Note the translocation from the cytoplasm to the nucleus upon hTNF-α treatment.
Each control slide contains formalin fixed, paraffin-embedded HCT 116 cells, both untreated and treated with hTNF-α, that serve as a control for NF-κB p65 immunostaining.
Transcription factors of the nuclear factor κB (NF-κB)/Rel family play a pivotal role in inflammatory and immune responses (1,2). There are five family members in mammals: RelA, c-Rel, RelB, NF-κB1 (p105/p50), and NF-κB2 (p100/p52). Both p105 and p100 are proteolytically processed by the proteasome to produce p50 and p52, respectively. Rel proteins bind p50 and p52 to form dimeric complexes that bind DNA and regulate transcription. In unstimulated cells, NF-κB is sequestered in the cytoplasm by IκB inhibitory proteins (3-5). NF-κB-activating agents can induce the phosphorylation of IκB proteins, targeting them for rapid degradation through the ubiquitin-proteasome pathway and releasing NF-κB to enter the nucleus where it regulates gene expression (6-8). NIK and IKKα (IKK1) regulate the phosphorylation and processing of NF-κB2 (p100) to produce p52, which translocates to the nucleus (9-11).
