Although no putative repressor has been identified so far, some genes of interest have been isolated. Further characterization is required to reveal their functions.

这些受CWC1调控的基因，尚需后续的探讨与分析，始能了解其於隐球菌蓝光反应中的角色。

We show that the expression of BCL11A, a repressor of human gamma-globin expression identified by genome-wide association studies, differs between mouse and human.

作为已被大量的基因组相关研究证实的一种人γ-球蛋白表达抑制剂，BCL11A的表达在鼠和人是不同的。

We discuss the relationship between repressor and

这样它与启动内的右侧重合，我们以后将细致的讨论阻遏子和RNase的关系。

BMI-1(B-cell-specific Moloney murine leukemia virus integration site 1), a Polycomb group repressor, is always present as a PcG complex combined with RING1, HPC2, Mph2, et al. BMI-1 prolongs cells'capacity to proliferate and represses their senescence by repressing the transcription of CDKN2A through acetylhydrolasing or deacetylhydrolasing the Polycomb response elements in chromosome.

BMI-1 (B-cell-specific Moloney murine leukemia virus integration site 1)属于PcG家族，它与该家族其他成员如RING1，HPC2，Mph2等结合形成蛋白复合体，作用于染色质PREs位点，通过对组蛋白进行乙酰化和去乙酰化修饰，从而稳定抑制CDKN2A转录，最终促进细胞的增殖并抑制细胞凋亡。

The RNA polymerase binding site is adjacent to OR2. This explains how repressor autogenously regulates its own synthesis.

它们排在抑制子的一个位点上，该位点与DNA 磷酸基因邻近，而这个磷酸基因也与RNA聚合酶邻近。

AIM: To investigate the effect of PD98059, a specific repressor of extracellular signal regulated kinase1/2 (ERK1/2), on the proliferation of the murine lymphocytes. METHODS: Lymphocytes were isolated from lymphoid nodes of BALB/c mouse. After stained with carboxy fluorescein diacetate, succinimidyl ester, the cells were stimulated with polyclonal activators, concanavalin and phorbol 12,13 dibutyrate plus ionomycin.

分离小鼠淋巴结细胞，藉羧基荧光素乙酰乙酸染色，用多克隆刺激剂刀豆A蛋白或者佛波醇酯加离子霉素刺激，以流式细胞术分析PD98059对淋巴细胞增殖的影响；利用碘化丙锭染色分析PD98059对细胞周期的影响。

ABSTRACT Hairy and Enhancer-of-split-type protein 1 (Hes1) is a main effecter of the Notch pathway and acts as a differentiation repressor and/or as a pro-expansion factor during the pancreatic development.

由于人们尚未找到胰腺干细胞的特异性标志，因而给胰腺干细胞的分离纯化及其特性的研究带来了极大的困难。来自hes1-/-敲除小鼠的研究提示，Hes1作为Notch信号通路的一个关键分子，在胰腺发育过程中扮演着扩增促进因子或分化抑制因子的角色，因而有可能用作胰腺干细胞的备选标志分子，但这一推论缺乏直接的证据。

Recent work in Arabidopsis demonstrates the molecular basis of this memory of winter: vernalization causes changes in the chromatin strcture of a flowering repressor gene, FLOWERING LOCUS, that switch this gene into a repressed state that is mitotically stable.

最近对拟南芥的研究显示了植物记忆冬季的分子基础：促进成熟促使一个开花抑制基因（FLOWERING LOCUS C，FLC）的染色质结构的改变，这种改变使这个基因从抑制状态转为有丝分裂稳定。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
