核转录因子 κB (NF-κB)/Rel 家族的转录因子,在炎症和免疫应答中发挥重要作用 (1,2)。在哺乳动物中有五个家族成员:RelA、c-Rel、RelB、NF-κB1 (p105/p50) 和 NF-κB2 (p100/p52)。p105 和 p100 都可由蛋白酶体经蛋白水解处理后,分别产生 p50 和 p52。Rel 蛋白结合 p50 和 p52 形成二聚体,二聚体再结合 DNA,调节转录活动。未刺激细胞中 NF-κB 被 IκB 抑制性蛋白阻隔在细胞浆中 (3-5)。NF-κB 活化剂可诱导 IκB 蛋白的磷酸化,并通过泛素-蛋白酶体通路将其靶标进行快速降解,释放 NF-κB 进入胞核,使其调节基因表达 (6-8)。NIK 和 IKKα (IKK1) 可调节 NF-κB2 (p100) 的磷酸化和加工以产生 p52,后者再转位入胞核 (9-11)。 Baeuerle, P.A. and Henkel, T.

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.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5 μl of NF-κB p65 (D14E12) XP® Rabbit 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。
