查询词典 transcription

These constructs, together with the construct containing the GUS gene expression cassette under the control of the Hsp70 promoter, were utilized in the co-bombardment experiments to identify viral cistrons that could activate the transcription directed by the Hsp70 promoter. We found that the P1, K2NIa and CP cistrons could independently activate the Hsp70 promoter.

用这些瞬时表达载体与含有Hsp70基因启动子指导下的GUS基因的表达载体共轰击豌豆叶片，发现P1、K2NIa和CP能诱导Hsp70基因启动子的转录活性，P1最强，K2NIa次之，而CP最弱，同时还发现P1基因的功能区域在127碱基以后。

Some stimulators, including viruses, tumor cells and hot shock, could promote the expression of NKG2 receptors and their ligands via activating certain transcription factors which are capable of up-regulating NKG2 promoters' activity. Meanwhile, epigenetic mechanisms including DNA methylation and histone posttranslational modifications are also critical to expression of NKG2 receptors and their ligands and may control the clonally distribution of some NK cell receptors.

病毒、肿瘤和热休克等刺激可以通过激活相应的转录调节因子，提高启动子活性而上调NKG2家族受体及其配体的表达，而启动子区DNA的甲基化状态、组蛋白的乙酰化和甲基化等表观遗传调控，在NK细胞受体及其配体的表达方面亦起重要作用，并决定NK细胞受体的克隆性分布。

In aid of the domain flexibility and requirement of cofactors, POU proteins exhibit very complicated ability to bind and recognize DNA in function of regulator and transcription factors.

遍及小肠上皮细胞的Ascl2转录因子的转基因表达，能够引起小肠绒毛上小囊的增生和异位。

ZmBH and ZmWD, containing bHLH or WD40-repeat demain, are unknown function transcription factor-like genes in maize. Under different treatments, various transcripts were determined in the two genes.

ZmBH、ZmWD是玉米中分别具有转录因子bHLH和WD重复蛋白结构的两个功能未知基因，在不同组织中及各种胁迫诱导条件下，这两个基因均发生不同程度的剪接，产生大小各异的转录本。

To satisfy the needs of the phoneticians in the study of speech sounds, a set of symbols called diacritics are added to broad transcription to show the more subtle differences between similar sounds.

为了满足语音学家研究语音的需求，一套叫做&附加符号&的标志添加到宽式标音法上来表明更加微妙的语音差别。（宽式标音法是一套仅用字母符号来标音的方法

Methods According to the examination result of vagina smears, 12 female rats were killed in proestrus, estrus, metaestrus and diestrus respectively, 3 for each, and their uterus and ovary were taken out, from which the total RNA and total protein were extracted for determination of transcription of SLC26A3 mRNA by RT-PCR, and expression of SLC26A3 protein by Western blot.

根据阴道涂片检测结果，将12只雌性Wister大鼠分别在动情前期、动情期、动情后期和动情间期断头处死，取出卵巢及子宫，提取总RNA及总蛋白，用RT-PCR及Western blot方法检测卵巢及子宫内SLC26A3在动情周期中各时期的表达。

The classical mechanism of E2 involves estrogen binding to receptors in the nucleus, after which the receptors dimerize and bind to specific response elements known as estrogen response elements located in the promoters of target genes. However, ERs can also regulate gene expression through protein-protein interactions with other DNA-binding transcription factors in the nucleus, or through regulation with production and activity of other genes.

除了与经典的雌激素反应元件结合引起基因转录外，也可通过蛋白质-蛋白质之间的相互作用而调节其他转录因子的转录激活作用，或者对其他转录因子生成或活性的影响而调节基因转录。

The authors speculate that loss of DNA binding impairs the transcription regulation of target genes in individuals with DYT6 dystonia.

作者推论，丧失DNA键结会造成DYT6肌张力障碍者之目标基因的转译调节不佳。

In addition to promoter regions, transcription of most eukaryotic genes is regulated by other dna sequences called enhancers.
