Chromatin IP

Chromatin IP

Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 106 Raji cells and either 5 µl of FoxP1 (D35D10) 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 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.

Forkhead box (Fox) proteins are a family of evolutionarily conserved transcription factors containing a sequence known as Forkhead box or winged helix DNA binding domain (1). The human genome contains 43 Fox proteins that are divided into subfamilies. The FoxP subfamily has four members, FoxP1 to FoxP4, which are broadly expressed and play important roles in organ development, immune response, and cancer pathogenesis (2-4). The FoxP subfamily has several characteristics that are atypical among Fox proteins: their Forkhead domain is located at the carboxy-terminal region, and they contain motifs that promote homo- and heterodimerization. FoxP proteins usually function as transcriptional repressors (4,5).

叉头盒(Fox)蛋白是进化保守转录因子家族之一,含有一个叉头盒或翼型螺旋DNA结合结构域的序列(1)。人类基因组含有43个叉头蛋白,并被分为亚家族。FoxP亚家族有四个成员FoxP1 到 FoxP4,它们广泛表达,并在器官发育,免疫反应和癌症病例中起重要作用(2-4)。FoxP亚家族有一些非典型的Fox蛋白的特点,就是它们的叉头结构域定位在羧基末端区域,它们含有的基序促进同源和异源二聚化。FoxP蛋白经常起着转录抑制因子功能(4,5).

FoxP1 plays an important role in cardiac valve and B cell development. Targeted deletion of FoxP1 in mice results in embryonic death at E14.5 with severe defects in cardiac outflow development, endocardial cushion morphogenesis, and myocyte proliferation and maturation (6). The FoxP1 gene is located on chromosome 3p14.1 and loss of heterozygosity of this region in multiple cancer types suggests a role for Foxp1 as a tumor suppressor (7). On the other hand, FoxP1 is highly expressed in a variety of B cell malignancies and is frequently involved in chromosome translocation, suggesting that FoxP1 may also act as an oncogene (8,9).FoxP1对心脏瓣膜和B细胞发育起重要作用,在小鼠中靶向敲出FoxP1会导致胚胎在E14,5时死亡,并有严重心脏血流发育和心内膜垫形态发生以及肌细胞增殖成熟的缺失(6),FoxP1基因坐落在染色体3p14.1,多种肿瘤中在这一区域的杂合子丢失,显示了Foxp1肿瘤抑制因子的作用(7)。另外,FoxP1在各种B细胞恶性肿瘤中高表达,高频率涉及染色体异位,暗示FoxP1也可能是癌基因(8,9).
