| 1 | PHF8 is a histone H3K9me2 demethylase regulating rRNA synthesis显示文摘histone H3 离氨酸 9 的 Dimethylation (H3K9me2 ) 是与抄写压抑联系的一个重要 epigenetic 标记。这里,我们识别了 PHF8, JmjC-domain-containing 蛋白质,为这个镇压标记特定的 histone demethylase。Recombinant 全身的野类型蛋白质能把 methylation 从 H3K9me2 移开,但是到丙氨酸 H247A 的保存 histidine 的变化废除 demethylase 活动。Overexpressed 外长的 PHF8 是 colocalized, B23 染色。内长的 PHF8 也是有 B23 和 fibrillarin 的 colocalized,二生长得很好的核蛋白质,建议那 PHF8 在核是局部性的并且可以调整 rRNA 抄写。确实, PHF8 跳了到 rDNA 基因的倡导者区域。减少的 PHF8 击倒 rRNA 的表示,和基因的 overexpression 导致了 rRNA 的 upregulation 抄本。附随地, H3K9me2 水平在 PHF8 击倒的房间在 rDNA 基因的倡导者区域被提高并且当野类型然而并非催化地不活跃的 H247A 变异的 PHF8 是 overexpressed 时,显著地减少了。因此,我们的学习为调整 rRNA 抄写的 H3K9me2 识别了 histone demethylase。 | Ziqi Zhu Yanru Wang Xia Li Yiqin Wang Longyong Xu Xiang Wang Tianliang Sun Xiaobin Dong Lulu Chen Hailei Mao Yi Yu Jingsong Li Pin Adele Chen Charlie Degui Chen | 2010 | Cell Research2010,20,7: | 7 |
| 2 | Redox-responsive ferrocene-containing poly(ionic liquid)s for antibacterial applications显示文摘Ferrocene(Fc)-containing imidazolium type ionic liquids(ILs) and corresponding poly(ionic liquid)(PIL) membranes with tunable antibacterial activity based on electrochemical redox reaction and host-guest chemistry were developed. The effect of Fc moiety on the antimicrobial activities against both Staphylococcus aureus(S. aureus) and Escherichia coli(E. coli) was studied by minimum inhibitory concentration(MIC). The presence of Fc groups highly enhanced the antibacterial efficiency of Fccontaining ILs because of the generation of reactive oxygen species(ROS). The electrochemical oxidation of Fc to Fc+and the formation of inclusion complexes between Fc and β-CD via host-guest interactions decreased the antibacterial activities of ILs and PIL membranes. The antibacterial activities may be recovered in some extent upon the electrochemical reduction of Fc+to Fc or the exclusion of the Fc out of the cavity of β-CD. Furthermore, all the Fc-containing PIL membranes showed relatively low hemolysis activities and none cytotoxicity toward human cells, indicating clinical feasibility in topical applications. | Tikai Zhang Jiangna Guo Yingying Ding Hailei Mao Feng Yan | 2019 | Science China Chemistry2019,62,1: | 3 |
| 3 | Coordinated regulation of active and repressive histone methylations by a dual-specificity histone demethylase ceKDM7A from Caenorhabditis elegans显示文摘H3K9me2 和 H3K27me2 是与抄写压抑联系的重要 epigenetic 标记,当 H3K4me3 与抄写激活被联系时。活跃、压抑的 histone methylations 以一种互相独占的方式散布,这被显示出,但是内在的机制糟糕被理解。这里,我们识别了 ceKDM7A,一个哲学博士(植物 homeodomain )- 并且 JmjC 包含域的蛋白质,为 H3K9me2 和 H3K27me2 特定的 histone demethylase。我们进一步证明 ceKDM7A 的 PHD 领域在染色体宽的水平绑了 H3K4me3 和与 ceKDM7A co 局部性的 H3K4me3。到 H3K4me3 的 PHD 域绑定的混乱在 vivo 减少了 demethylase 活动,并且 ceKDM7A 的损失减少了它的联系目标基因的表达式。这些结果显示 ceKDM7A 被招募到倡导者到 demethylate H3K9me2 和 H3K27me2 并且通过 PHD 领域的绑定激活基因表示到 H3K4me3。因此,我们的学习识别双特性的 histone demethylase 并且提供新奇卓见进 histone methylation 的规定。 | Hanqing Lin Yiqin Wang Yanru Wang Feng Tian Pu Pu Yi Yu Hailei Mao Ying Yang Ping Wang Lulu Hu Yan Lin Yi Liu Yanhui Xu Charlie Degui Chen | 2010 | Cell Research2010,20,8: | 2 |

| 5 | Enzyme-Induced Carbonate Precipitation for the Protection of Earthen Dikes and Embankments Under Surface Runoff: Laboratory Investigations显示文摘Earthen structures such as shore protection dikes and river embankments easily suffer from erosion under surface water runoff.This study made experimental efforts to explore the enzyme-induced carbonate precipitation(EICP)method for slope erosion control under surface runoff for earthen structures.The sandy soils were treated by the EICP method for various rounds.Surface characteristics were evaluated by the surface penetration resistance,calcium carbonate content,and surface hard crust thickness of EICP-treated soils.Slope runoff erosion experiments were carried out to evaluate the erosion control performances of the EICP treatment.The surface penetration resistance,calcium carbonate content,and surface hard crust thickness were found to significantly increase with the treatment rounds.In the erosion experiments,it was observed that the level of damages decreased and the water flow volume required to trigger the damage increased with more treatments.The increase in the soil slope angle led to more serious surface damages.The amount and rate that the soil particles were eroded from the slope surfaces declined with more EICP treatments,which was consistent with those of visual observations.The preliminary investigations presented in this study have shown the potential of the EICP method for slope erosion control under surface runoff for earthen structures. | HE Jia FANG Changhang MAO Xunyu QI Yongshuai ZHOU Yundong KOU Hailei XIAO Liang | 2022 | Journal of Ocean University of China2022,21,2: | 0 |
| 6 | 固液界面的离子束分析显示文摘Investigations of the microstructure formation and elemental formation at the solid-liquid interfaces are of great significance due to the various valuable applications such as super-capacitors,battery,medical implantation and electrochemical industry and research.Traditional ion beam analysis is performed in vacuum which just allows investigation of solid samples.Liquids interface with a solid surface are not accessible for the vacuum measurements in the ion beam laboratory.By utilizing a silicon nitride vacuum window coated with 10 nm aluminum we built up an enclosed chamber,which can hold solution in vacuum and is able to perform precise elemental analysis by means of ion beam analysis at the solid-liquid interface.By utilizing a silicon nitride vacuum window coated with several nm aluminum we built up an enclosed chamber,which can hold solution in vacuum and is able to perform precise elemental analysis by means of ion beam analysis at the solid-liquid interface the chamber of the solid-liquid interface probe used the aluminum layer as electrode,which allowed online apply and adjust the electric field at the interface. | Li Xiaoyue Du Guanghua Yu Tao Zhang Hailei Shen Hao Guo Jinlong Wu Ruqun Liu Wenjing Li Yaning Zhao Jing Mao Guangbo Shen Cheng | 2018 | IMP & HIRFL Annual Report2018,,1: | 0 |
