背景 | ATP-dependent chromatin remodeling complexes play an essential role in the regulation of various nuclear processes, such as gene expression, DNA replication, and repair (1,2). The SWI/SNF chromatin remodeling complex consists of more than 10 subunits with a single molecule of the ATPase catalytic subunit BRM or BRG1, but not both. The activities of these two subunits drive the disruption of histone-DNA contacts that lead to changes in accessibility of crucial regulatory elements within chromatin (2-5). The BRM/BRG1 containing SWI/SNF complexes are recruited to target promoters by transcription factors, such as nuclear receptors, p53, RB, and BRCA1 to regulate gene activation, cell growth, the cell cycle, and differentiation processes (1,6-9). BRM and BRG1 are also considered to be tumor suppressors and their expression levels are severely reduced in several cancer cell lines (10-13). |

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 MCF7 cells grown in phenol red free medium and 5% charcoal stripped FBS for 4 d followed by treatment with β-estradiol (10 nM, 45 min) and either 5 μl of BRM (D9E8B) 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 ESR1 Promoter Primers #9673, SimpleChIP® Human pS2 Promoter Primers #9702, 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. 染色质免疫沉淀反应利用4×106MCF细胞进行染色质交联。MCF细胞在含有5%活性炭去除FBS的无酚红培养基中生长4天后,利用β-雌二醇(10nm, 45min) 处理,同时利用SimpleChIP® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003试剂盒进行分析,采用抗体或为5ul BRM (D9E8B) XP® Rabbit mAb 或为2ul Normal Rabbit IgG #2729。利用SimpleChIP® 人ESR1启动子引物#9673, SimpleChIP® 人PS2启动子引物 #9702, and SimpleChIP® 人α Satellite repeat 引物#4486对DNA含量进行实时PCR.每个样品中免疫沉淀的DNA的量以相对于总的染色质量的比值呈现。 | |
