TTF-1 was found to be positive in 8 of 48 (16.6%) nephroblastomas and negative in all 5 metanephric adenomas. WT1 was positive in 43 of 48 (89.6%) nephroblastomas and 4 of 5 (80.0%) metanephric adenomas.

在他的肺部转移灶中，我们意外观察到瘤细胞核的甲状腺转录因子1（TTF-1）的免疫反应与Wilms氏瘤1型蛋白（WT1）免疫反应的明显缺失相关。

We amied the BCP sequence and the preS2 gene sequence of HBV separately as the target region, according to HBV DNA sequence of Chinese strain, synthesized the set of specific primers, amplified the sequence by PCR method from the serum of patients with CHI, verified by restriction analysis, subcloned into pGEM Teasy vectors, employed polyacrylamide gel electrophoresis to display the deletion mutation and selected the clones with differential length to be sequenced.

本研究应用PCR技术及其他分子生物学技术，分别以HBV转录调控序列BCP以及表面蛋白编码序列pre S2为靶基因，以中国株HBV基因序列为依据，设计特异性多聚酶链反应引物，分别自43例、51例慢性HBV感染患者血清中扩增出目的片段，构建质粒Teasy-BCP和Teasy-pre S2，酶切鉴定后，采用聚丙烯酰胺凝胶电泳技术展示缺失突变，再经DNA测序以了解在慢性乙型肝炎患者体内的病毒变异情况。

This study focused on the mRNA decay process of the transcripts of the candidate sterile gene in maize Zea mays L.

本研究对玉米S型细胞质雄性不育中胞质不育候选基因的转录产物在核恢复基因的作用下被降解并引起育性恢复的生物学机理进行了探讨。

The effect of cyclin C on zygotic transcription activation during vertebrate embryonic development is poorly understood.

在脊椎动物胚胎发育过程中有关细胞周期蛋白C合子型转录激活机制尚知甚少。

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。

The RT-PCR of coronas has v, as positive in three (18.8%) of sixteen throat swabs and in none (0%) of seven rectal swabs.

冠状病毒RNA是用反录型的聚合多链反应酶来检测，共侦测喉头检体十六例，血清检体二例及肛门检体七例。

Supplementation of folate in diets may reduce hyperhomocysteinemia induced by excess intake of methionine and decrease the expression of NF-κBP65 protein and monocyte chemoattractant protein-1 (MCP-1) in carotid common artery after balloon angioplasty, These data show that Hcy may exacerbate neointima hyperplasia after denuding injury by increasing the expression of inflammatory factors via the activation of NF-kB, Folate can reverse the effect of Hcy on the activation of NF-κB and the expression of MCP-1, an effect of preventing the restenosis postangioplasty.

而Hcy有可能通过激活核转录因子通路增加损伤血管组织炎症因子的表达而加重血管球能损伤后新内膜的过度增生过程，叶酸能对抗Hcy的上述作用，对高同型半胱氨酸血症引起的血管成形术后再狭窄可能有一定的预防作用。
