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。
