Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 Raji cells and either 5 µl of BCL6 (D65C10) 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 BCL2 Promoter Primers #12924, SimpleChIP® Human HSP90B1 Promoter Primers #12899, 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.


Chromosomal translocations result in misregulation of the proto-oncogene BCL6 in patients with B cell-derived non-Hodgkins lymphoma (1). The BCL6 gene is selectively expressed in mature B cells and encodes a nuclear phosphoprotein that belongs to the BTB/POZ zinc finger family of transcription factors (2,3). BCL6 protein can bind to target DNA sequences of Stat6 and, analogous to Stat6, modulate the expression of interleukin-4-induced genes (4). Furthermore, BCL6 restrains p53-dependent senescence, making BCL6-active tumors functionally p53-negative (5). The mitogen-activated protein kinases, Erk1 and Erk2, but not JNK, phosphorylate BCL6 at multiple sites. Phosphorylation of BCL6 at Ser333 and Ser343 results in degradation of BCL6 by the ubiquitin/proteasome pathway in B cells (6,7). In addition, BCL6 is acetylated and its transcriptional repressor function is inhibited by the transcriptional co-activator p300 (8).

在B细胞起源的非霍奇金淋巴瘤病人中,染色体易位导致了对原癌基因Bcl-6 的调节失去准确性(1)。 The Bcl-6在成熟的B细胞中选择性表达并编码了属于BTB/POZ锌指蛋白家族转录调控因子的核磷酸化蛋白(2-3)。Bcl-6 蛋白能结合到Stat6蛋白和同源蛋白的目标DNA序列,调节白细胞介素-4诱导基因的表达(4)。另外,Bcl-6抑制了p53依赖的衰老,使得Bcl-6激活肿瘤功能上p53成为负因素(5)。分裂原活化蛋白激酶Erk1和Erk2, 而不是JNK, 在多位点磷酸化 Bcl-6。在B细胞中,磷酸化位于Bcl-6的Ser333 和 Ser343位点导致了Bcl-6被泛素/蛋白酶体通路降解(6-7)。另外, Bcl-6 被乙酰化后其转录抑制的功能也被转录共激活因子p300所抑制(8)。
