| 1 | Simultaneous cotargeting of ATR and RNA Polymerase I transcription demonstrates synergistic antileukemic effects on acute myeloid leukemia显示文摘Dear Editor,Continued development of novel therapeutic agents is critical to improve the survival of patients with acute myeloid leukemia(AML).RNA Polymerase I(Pol I)-mediated transcription and ribosomal biogenesis become dysregulated,thereby allowing synthesis of necessary substrates to support uncontrolled cancer cell proliferation 1.The Pol I transcription rate is higher in AML cells than nonleukemic myeloid precursors 2,suggesting Pol I transcrip-tion as a therapeutic target for AML.CX-5461 is a potent Pol I transcription inhibitor and stabilizer of the DNA G-quadruplex structure,which causes G2/M-phase arrest via the ATR(ataxia telangiectasia and Rad3-related protein)-mediated DNA damage response(DDR)3–5. | Tingting Wang Margaret Shatara Fangbing Liu Tristan Knight Holly Edwards Guan Wang Hai Lin Yue Wang Jeffrey W.Taub Yubin Ge | 2019 | Signal Transduction and Targeted Therapy2019，4，1： | 1 |

| 3 | Double knock-in pig models with elements of binary Tet-On and phiC31 integrase systems for controllable and switchable gene expression显示文摘Inducible expression systems are indispensable for precise regulation and in-depth analysis of biological process.Binary Tet-On system has been widely employed to regulate transgenic expression by doxycycline.Previous pig models with tetracycline regulatory elements were generated through random integration.This process often resulted in uncertain expression and unpredictable phenotypes,thus hindering their applications.Here,by precise knock-in of binary Tet-On 3G elements into Rosa26 and Hipp11 locus,respectively,a double knock-in reporter pig model was generated.We characterized excellent properties of this system for controllable transgenic expression both in vitro and in vivo.Two att P sites were arranged to flank the td Tomato to switch reporter gene.Single or multiple gene replacement was efficiently and faithfully achieved in fetal fibroblasts and nuclear transfer embryos.To display the flexible application of this system,we generated a pig strain with Dox-inducing h KRASexpression through phiC31 integrase-mediated cassette exchange.After eight months of Dox administration,squamous cell carcinoma developed in the nose,mouth,and scrotum,which indicated this pig strain could serve as an ideal large animal model to study tumorigenesis.Overall,the established pig models with controllable and switchable transgene expression system will provide a facilitating platform for transgenic and biomedical research. | Qin Jin Xiaoyu Yang Shixue Gou Xiaoyi Liu Zhenpeng Zhuang Yanhui Liang Hui Shi Jiayuan Huang Han Wu Yu Zhao Zhen Ouyang Quanjun Zhang Zhaoming Liu Fangbing Chen Weikai Ge Jingke Xie Nan Li Chengdan Lai Xiaozhu Zhao Jiaowei Wang Meng Lian Lei Li Longquan Quan Yinghua Ye Liangxue Lai Kepin Wang | 2022 | Science China(Life Sciences)2022，65，11： | 1 |
| 4 | A hybrid monolithic column based on flower-shaped zeolitic imidazolate framework for efficient capillary microextraction of brominated flame retardants显示文摘A novel flower-shaped zeolitic imidazolate framework(ZIF) doped organic-inorganic hybrid monolithic column(ZIF-HMC) was prepared by a simple sol-gel 'one-step' method and utilized for efficient capillary microextraction(CME) of four brominated flame retardants.The prepared monolithic was characterized by Fourier transform infrared,scanning electron microscopy,X-ray photoelectron spectroscopy,energy disperse spectroscopy,and N_(2) adsorption-desorption.The parameters of CME were optimized by orthogonal array design.Under the optimal conditions,the ZIF-HMC showed excellent extraction efficiency,the limit of detection(LODs) and the limit of quantification(LOQs) were in the range of0.52$3.1 mg/L and 1.7$10 mg/L,respectively,and the proposed method demonstrated good recovery(88.8%–116.6%) with the RSD less than 13.6% and a reusability of at least 30 times.The ZIF-HMC possessed great potential for separating organic pollutants and the strategy used here could be extended to prepare other derivatized HMC functionalized monoliths. | Xuemei Wang Xinglan Cui Hong Ji Fangbing Wang Yacong Liu Xinzhen Du Xiaoquan Lu | 2021 | Chinese Chemical Letters2021，32，10： | 0 |
| 5 | Electrochemical conversion of furfural to furoic acid:a more stable,efficient and energy-saving system显示文摘The paired electrolytic system is constructed by combining the valuable organic electro-oxidation and electro-reduction reactions,which can replace the ineffective water splitting half-reaction.By reducing the energy consumption of the electrolytic cell,the value-added electrolysis is realized.The indirect electrolysis method greatly reduces the dependence of the organic electrolysis reaction on electrode potential by introducing the redox mediators,which solves the problem on the matching of anode and cathode current under potentiostatic conditions.Here,we report a more stable,efficient and energy-saving linear paired electrochemical synthesis system that can simultaneously convert furfural to furoic acid at both the anode and cathode at higher current densities.Stable three-dimensional networked PbO_(2)is used as the anode and the catalytic amount of 2,2,6,6-tetramethyl-1-piperidinyloxy(TEMPO)is used as the mediator to realize the efficient conversion of furfural to furoic acid in a wide potential range.The cathode catalyzes two-electron oxygen reduction to hydrogen peroxide using Pb/RHPC gas-diffusion electrode,which mediates the oxidation of furfural to furoic acid simultaneously.In potentiostatic electrolysis,the selectivity of the furoic acid in the cathode and anode is 33.2%and 99.3%,respectively,and the total electron efficiency is 127.1%.The properties of the cathode and anode remain stable after the long-time electrolysis in a flow cell.By choosing a stable anode with high oxygen evolution overpotential and a gas-diffusion cathode with high hydrogen evolution overpotential,the electrolytic cell can be operated efficiently and stably by introducing reasonable mediated reactions.The two half-reactions have good compatibility during the electrolysis process,saving energy consumption by about 12.3%,for certain industrial application prospects. | Xinxin Li Linchuan Cong Haibo Lin Fangbing Liu Fuyu Han Nan Lin | 2022 | Science China Chemistry2022，65，12： | 0 |
| 6 | Linear paired electrolysis of furfural to furoic acid at both anode and cathode in a multiple redox mediated system显示文摘Implementing a new energy-saving electrochemical synthesis system with high commercial value is a strategy of the sustainable development for upgrading the bulk chemicals preparation technology in the future.Here,we report a multiple redox-mediated linear paired electrolysis system,combining the hydrogen peroxide mediated cathode process with the I2 mediated anode process,and realize the conversion of furfural to furoic acid in both side of the dividedflow cell simultaneously.By reasonably controlling the cathode potential,the undesired water splitting reaction and furfural reduction side reactions are avoided.Under the galvanostatic electrolysis,the two-mediated electrode processes have good compatibility,which reduce the energy consumption by about 22%while improving the electronic efficiency by about 125%.This system provides a green electrochemical synthesis route with commercial prospects. | Xinxin Li Linchuan Cong Haibo Lin Fangbing Liu Xiangxue Fu Hai-Chao Xu Nan Lin | 2024 | Green Energy & Environment2024，9，1： | 0 |
