| 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).转录调控因子的核因子κ B(NF-κB)/Rel 家族在炎症反应和免疫反应中发挥了至关重要的作用(1,2)。在哺乳动物中一共有5个家族 : RelA, c-Rel, RelB, NF-κB1 (p105/p50), 和 NF-κB2 (p100/p52)。 p105 和 p100 在蛋白水解酶的作用下分别形成p50 和 p52。p50 和 p52形成二聚体并结合Rel蛋白，此复合体能够结合到DNA上调控转录。在未刺激的状态下， NF-κB 在IκB抑制剂作用下在细胞质中处于非活性状态(3-5)。 NF-κB激活因子能够诱导 IκB 蛋白的磷酸化, 这就使IκB能够快速的经过泛素化-蛋白酶通路降解从而释放 NF-κB，激活的NF-κB入核调控基因的表达(6-8)。 NIK 和 IKKα (IKK1) 调节磷酸化并促使NF-κB2 (p100) 生成p52, p52入核(9-11)。 |

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 HeLa cells treated with Human Tumor Necrosis Factor-α (hTNF-α) #8902 (30 ng/ml, 1 hr) and either 10 μl of NF-κB p65 (L8F6) Mouse 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.染色质免疫共沉淀。HeLa细胞培养至4 x 106，并用hTNF-α #8902 (30 ng/ml, 1 hr)处理后，将染色质交联到玻片上,然后用SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003进行免疫沉淀实验,本实验中用10 μl NF-κB p65 (L8F6) Mouse mAb 抗体或2 μl Normal Rabbit IgG #2729 。对富集的DNA做real-time PCR,所用引物为SimpleChIP® Human IκBα Promoter Primers #5552, human IL-8 promoter primers和SimpleChIP® Human α Satellite Repeat Primers #4486。每个样本中沉淀的DNA量定义为相对信号与输入的总染色质相比的数值。 | |
