背景 | Transcription factors of the nuclear factor κ B (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 is then translocated to the nucleus (9-11). |

Flow cytometric analysis of HeLa cells, untreated (blue) or TNF-α-treated (green), using Phospho-NF-κB p65 (Ser536) (93H1) Rabbit mAb compared to a nonspecific negative control antibody (red). | |
Western blot analysis of extracts from HeLa and NIH/3T3 cells, untreated or TNF-α treated (#2169, 20 ng/ml for 5 minutes), using Phospho-NF-κB p65 (Ser536) (93H1) Rabbit mAb (upper) or NF-κB p65 Antibody #3034 (lower). | |
Confocal immunofluorescent analysis of HeLa cells, untreated (left) and TNF-α treated (#8902 at 20 ng/ml for 20 min, right), using Phospho-NF-κB p65 (Ser536) (93H1) Rabbit mAb (green). Actin filaments have been labeled with Alexa Fluor® phalloidin 555 (red). | |
Western blot analysis of extracts from THP-1 cells, differentiated with TPA (#9905, 80 nM for 24h) and treated with 1 μg/ml LPS for the indicated times, using Phospho-NF-κB p65 (Ser536) (93H1) Rabbit mAb (upper) and NF-κB p65 (C22B4) Rabbit mAb #4764 (lower). | |
Confocal immunofluorescent analysis of HT-1080 cells, untreated (left) or treated with hTNF-α #8902 (20 ng/ml, 20 min) (right), using NF-κB p65 (D14E12) XP® Rabbit mAb (green). Actin filaments were labeled with DY-554 phalloidin (red). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye). | |
Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 HeLa cells treated with hTNF-α #8902 (30 ng/ml, 1 hr) and either 5 μl of NF-κB p65 (D14E12) XP® Rabbit mAb or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by Real-Time PCR using SimpleChIP® Human IκBα Promoter Primers #5552, human IL-8 promoter primers, and SimpleChIP® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one. | |
