Receiving signals from any kinds of cascades, a number of transcription factors have been implicated as direct mediators of hypertrophic gene expression including SPl, Elk-1, SRF, MEF-2, GATA, and LIM proteins.

目前虽然认为心肌肥大的发病机制与细胞外的心肌肥大因子刺激、细胞内的信号转导和核内的某些基因活化有关，但其最本质的特征是心肌细胞基因表达的异常。

Methods Differential display reverse transcription polymerase chain reaction was carried out to screen the differentially expressed gene fragments from the lateral geniculate body and the visual cortex.

利用差异显示反转录PCR技术分析大鼠外侧膝状体与视皮层基因差异表达情况，并筛选差异表达基因片段。

The regulation of KUP/HAK/KT families mainly occurs on transcription level and the regulation of K(superscript +) channel proteins is mainly a post-translation regulation.

KUP/HAK/KT家族基因的调节，主要是转录水平的调节，而K通道蛋白的调节则可能主要是一种翻译后调节。

Four field strains of infectious bronchitis viruswere isolated from chicken kidney, trachea and lung of the young layer flocks in some regions of Shaanxi province. Biological characterizations of the virus were investigated by virus pathogenicity to chicken embryo and healthy chickens, hemagglutination test, hemagglutination inhibition test, dwarfing embryonated chicken eggs, electron microscopy and reverse transcription polymerase chain reaction. It demonstrated that allantoic fluid of each passage virus could hemagglutinate chicken red blood cells by treatment with 1% trypsin. The standard positive serum to IBV could inhibited the hemagglutination. The isolates could make respiratory and kidney diseases in chickens.

采集陕西省宝鸡市、扶风县、兴平市和榆林市等地鸡场疑似传染性支气管炎发病鸡病料，通过9～11 日龄非免疫鸡胚进行了病毒的实验室分离和传代，并对分离毒株进行了病毒的血凝性、血凝抑制性、致病性、鸡胚矮小化、电镜特征等生物学特性鉴定，结果表明，4 株分离株经1%胰酶处理后的各代病毒尿囊液均可凝集鸡红细胞，标准阳性血清可特异性的抑制其凝集性，回归试验可复制出与自然发病相同的病例，病毒传代物有明显的致鸡胚矮小化作用，透射电镜下可见有近似球形、直径100 nm左右的冠状病毒粒子，将分离鉴定的4 株IBV 定名为BJ-04、FF-04、XP-03 和YL-04。

Silenced chromatin, largely heterochromatic,contains a number of restrictive histone modifications, such as meH3K9, meH3K27, meH4K20,and histone deacetylation, which allow for a higher-order packing and inaccessibility to transcription factors.

沉默的染色质，大部分的是异染色质，包含大量的限制性的组蛋白修饰因子，例如meH3K9， meH3K27， meH4K20和组蛋白的脱乙酰作用，这些因子需要高度包装和不易转录因子。

The CCAAT binding factor of brewer's yeast Saccharomyces cerevisiae has been shown previously to be a heteromeric complex containing HAP2, HAP3, HAP4 and HAP5 subunits. This factor can bind specifically to CCAAT-containing upstream sites within the promoters of numerous yeast genes, and then activate the transcription.

HAP转录因子(HAP2/HAP3/HAP4/HAP5)是存在于酿酒酵母中的一种异源多聚蛋白，它能与酵母中许多启动子上游的CCAAT盒专一性结合，以增强基因的转录。

TGF-βbinds to a heteromeric complex of type I and type II receptors. The constitutively active type II receptor phosphorylates and activates the type I receptor which phosphorylates Smad2 and Smad3 (receptor-associated Smads). Receptor-associated Smads bind the common mediator Smad4 and are translocated to the nucleus, where they associate with DNA-binding cofactors to modulategene transcription.

TGF-β与其效应细胞表面的Ⅱ型受体TβRⅡ和Ⅰ型受体TβRⅠ形成的异源二聚体结合，相继激活TβRⅡ和TβRⅠ，活化的TβRⅠ再进一步活化Smad2和Smad3，磷酸化的Smad2/3必须与Smad4结合形成复合物，才能进入细胞核，调节靶基因的转录[6]。

Plant homeotic genes and homeobox genes are two types of the important genes encoding transcription factors involved in plant development.

植物同源异型基因及同源异型盒基因是涉及植物个体发育调节的两类重要转录因子编码基因。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
