In summary, the BRD7 gene acted as a candidate of tumor suppressor gene with NPC. The overexpression of BRD7 can partly reverse malignant phenotype of NPC cell line. The suppression effect of BRD7 on NPC tumorigenesis my be achieved by recognizing acetylated histone peptide through their motif-bromodomain, then modulating gene transcription by taking part in histone acetylating and chromosome remodeling, finally influencing signal-transduction pathways.

综上所述，BRD7基因作为一个重要的鼻咽癌抑瘤基因侯选者，在鼻咽癌细胞中的过表达后，可导致鼻咽癌细胞 HNE蛋白质表达谱发生改变，逆转其恶性表型，其作用机理可能是：BRD7基因通过其功能域彭聪硕士学位论文10Bromodomain与乙酚化的组蛋白特异性结合，参于染色体的乙酚化，染色质的组装，从而影响基因转录的调控，最终影响细胞内的信号传导通路并实现对细胞周期的调控，从而发挥抑制鼻咽癌细胞生长的作用。

To understand the listed contents:the studies about component of nuclear pore complex; the main functions of gp210;the different configuration models of sequence specific DNA-binding proteins; karyotype and chromosome bandings; configuration of chromatin and dene transcription; nuclear bodies is many subnuclear domains which have different conformation between chromatin.

In order to develop a new path for gene mapping of fish, the digoxigenin and tritium labeled in situ hybridization techniques combined with multiple banding analysis on the pachytene bivalents of M. albus were studied using the wheat ribosomal RNA genes, pig growth hormone gene and MaSoxl (M. albus SRY boxl) DNA segment as the probes. Moreover, the techniques of random primed in situ DNA synthesis were also developed on the bivalents of M.
