| 1 | Reactivation of γ-globin expression through Cas9 or base editor to treat β-hemoglobinopathies显示文摘Dear Editor,Mutations in the β-globin gene,the essential component of adult hemoglobin(HbA;a2p2),results in either a production of aberrant sickle hemoglobin(HbS)leading to sickle cell disease(SCD)or an insufficient β-globin synthesis leading to β-thalassemia.These two major forms of β-hemoglobinopathies cause impaired erythropoiesis and life-threatening anemia.Clinical evidence has suggested that reaaivation of fetal γ-globin(HBG)gene expression which is normally silenced after birth by certain genetic mutations can ameliorate the clinical course of β-hemoglobinopathies. | Liren Wang Linxi Li Yanlin Ma Handan Hu Qi Li Yang Yang Wenbang Liu Shuming Yin Wei Li Bin Fu Ryo Kurita Yukio Nakamura Mingyao Liu Yongrong Lai Dali Li | 2020 | Cell Research2020，30，3： | 14 |

| 3 | A wireless, implantable optoelectrochemical probe for optogenetic stimulation and dopamine detection显示文摘Physical and chemical technologies have been continuously progressing advances in neuroscience research.The development of research tools for closed-loop control and monitoring neural activities in behaving animals is highly desirable.In this paper,we introduce a wirelessly operated,miniaturized microprobe system for optical interrogation and neurochemical sensing in the deep brain.Via epitaxial liftoff and transfer printing,microscale light-emitting diodes(micro-LEDs)as light sources and poly(3,4-ethylenedioxythiophene)polystyrene sulfonate(PEDOT:PSS)-coated diamond films as electrochemical sensors are vertically assembled to form implantable optoelectrochemical probes for real-time optogenetic stimulation and dopamine detection capabilities.A customized,lightweight circuit module is employed for untethered,remote signal control,and data acquisition.After the probe is injected into the ventral tegmental area(VTA)of freely behaving mice,in vivo experiments clearly demonstrate the utilities of the multifunctional optoelectrochemical microprobe system for optogenetic interference of place preferences and detection of dopamine release.The presented options for material and device integrations provide a practical route to simultaneous optical control and electrochemical sensing of complex nervous systems. | Changbo Liu Yu Zhao Xue Cai Yang Xie Taoyi Wang Dali Cheng Lizhu Li Rongfeng Li Yuping Deng He Ding Guoqing Lv Guanlei Zhao Lei Liu Guisheng Zou Meixin Feng Qian Sun Lan Yin Xing Sheng | 2020 | Microsystems & Nanoengineering2020，6，1： | 3 |

| 5 | Optoelectronic sensing of biophysical and biochemical signals based on photon recycling of a micro-LED显示文摘Conventional bioelectrical sensors and systems integrate multiple power harvesting,signal amplification and data transmission components for wireless biological signal detection.This paper reports the real-time biophysical and biochemical activities can be optically captured using a microscale light-emitting diode(micro-LED),eliminating the need for complicated sensing circuit.Such a thin-film diode based device simultaneously absorbs and emits photons,enabling wireless power harvesting and signal transmission.Additionally,owing to its strong photon-recycling effects,the micro-LED^photoluminescence(PL)emission exhibits a superlinear dependence on the external conductance.Taking advantage of these unique mechanisms,instantaneous biophysical signals including galvanic skin response,pressure and temperature,and biochemical signals like ascorbic acid concentration,can be optically monitored,and it demonstrates that such an optoelectronic sensing technique outperforms a traditional tethered,electrically based sensing circuit,in terms of its footprint,accuracy and sensitivity.This presented optoelectronic sensing approach could establish promising routes to advanced biological sensors. | He Ding Guoqing Lv Zhao Shi Dali Cheng Yang Xie Yunxiang Huang Lan Yin Jian Yang Yongtian Wang Xing Sheng | 2021 | Nano Research2021，14，9： | 2 |
| 6 | Design, synthesis and in vitro antitumor evaluation of novel diaryl urea derivatives bearing sulfonamide moiety显示文摘A novel series of diaryl urea derivatives bearing sulfonamide moiety have been designed and synthesized.Their in vitro antitumor effect against human cancer cell lines MX-1,A375,HepG2,Ketr3 and HT-29 was screened and evaluated by the standard MTT assay with sorafenib as the positive control.Some of the compounds showed significant inhibitory activity against multiple cell lines compared to sorafenib.In particular,2,6-dimethyl-4-{6-[3-(4-chloro-3-(trifluoromethyl)phenyl)urea]naphthalen-2-yl}sulfonyl morpholine(10d)was found to be the most potent against A375,HepG2 and Ketr3 with IC50values of 0.65–0.97mol/L,which were 5–20-fold more potent than sorafenib.Compound 10d emerged as a valuable lead for further optimization. | LUO Can TANG Ke LI Yan YIN DaLi CHEN XiaoGuang HUANG HaiHong | 2013 | Science China Chemistry2013，56，11： | 2 |
| 7 | Inhibition of aberrant Hif1αactivation delays intervertebral disc degeneration in adult mice显示文摘The intervertebral disc(IVD) is the largest avascular tissue. Hypoxia-inducible factors(HIFs) play essential roles in regulating cellular adaptation in the IVD under physiological conditions. Disc degeneration disease(DDD) is one of the leading causes of disability, and current therapies are ineffective. This study sought to explore the role of HIFs in DDD pathogenesis in mice. The findings of this study showed that among HIF family members, Hif1α was significantly upregulated in cartilaginous endplate(EP) and annulus fibrosus(AF) tissues from human DDD patients and two mouse models of DDD compared with controls. Conditional deletion of the E3 ubiquitin ligase Vhl in EP and AF tissues of adult mice resulted in upregulated Hif1α expression and age-dependent IVD degeneration. Aberrant Hif1α activation enhanced glycolytic metabolism and suppressed mitochondrial function. On the other hand, genetic ablation of the Hif1α gene delayed DDD pathogenesis in Vhl-deficient mice. Administration of 2-methoxyestradiol(2ME2), a selective Hif1α inhibitor, attenuated experimental IVD degeneration in mice. The findings of this study show that aberrant Hif1α activation in EP and AF tissues induces pathological changes in DDD, implying that inhibition of aberrant Hif1α activity is a potential therapeutic strategy for DDD. | Zuqiang Wang Hangang Chen Qiaoyan Tan Junlan Huang Siru Zhou Fengtao Luo Dali Zhang Jing Yang Can Li Bo Chen Xianding Sun Liang Kuang Wanling Jiang Zhenhong Ni Quan Wang Shuai Chen Xiaolan Du Di Chen Chuxia Deng Liangjun Yin Lin Chen Yangli Xie | 2022 | Bone Research2022，10，1： | 1 |

| 15 | A de novo missense mutation in MPP2 confers an increased risk of Vogt–Koyanagi–Harada disease as shown by trio-based whole-exome sequencing显示文摘Vogt–Koyanagi–Harada(VKH)disease is a leading cause of blindness in young and middle-aged people.However,the etiology of VKH disease remains unclear.Here,we performed the first trio-based whole-exome sequencing study,which enrolled 25 VKH patients and 50 controls,followed by a study of 2081 VKH patients from a Han Chinese population to uncover detrimental mutations.A total of 15 de novo mutations in VKH patients were identified,with one of the most important being the membrane palmitoylated protein 2(MPP2)p.K315N(MPP2-N315)mutation.The MPP2-N315 mutation was highly deleterious according to bioinformatic predictions.Additionally,this mutation appears rare,being absent from the 1000 Genome Project and Genome Aggregation Database,and it is highly conserved in 10 species,including humans and mice.Subsequent studies showed that pathological phenotypes and retinal vascular leakage were aggravated in MPP2-N315 mutation knock-in or MPP2-N315 adeno-associated virus-treated mice with experimental autoimmune uveitis(EAU).In vitro,we used clustered regularly interspaced short palindromic repeats(CRISPR‒Cas9)gene editing technology to delete intrinsic MPP2 before overexpressing wild-type MPP2 or MPP2-N315.Levels of cytokines,such as IL-1β,IL-17E,and vascular endothelial growth factor A,were increased,and barrier function was destroyed in the MPP2-N315 mutant ARPE19 cells.Mechanistically,the MPP2-N315 mutation had a stronger ability to directly bind to ANXA2 than MPP2-K315,as shown by LC‒MS/MS and Co-IP,and resulted in activation of the ERK3/IL-17E pathway.Overall,our results demonstrated that the MPP2-K315N mutation may increase susceptibility to VKH disease. | Xianyang Liu Jiayu Meng Xingyun Liao Yusen Liu Qian Zhou Zongren Xu Shuming Yin Qingfeng Cao Guannan Su Siyuan He Wanqian Li Xiaotang Wang Guoqing Wang Dali Li Peizeng Yang Shengping Hou | 2023 | Cellular & Molecular Immunology2023，20，11： | 0 |
| 16 | Tracing drug release process with dual-modal hyperbranched polymer-gold nanoparticle complexes显示文摘Dual-modal surface enhanced Raman spectrum(SERS)-fluorescence polymer/metal hybrid complexes have been prepared for tracing drug release process in tumor cells. Firstly, the hyperbranched poly((S-(4-vinyl) benzyl S′-propyltrithiocarbonate)-co-(poly(ethylene glycol) methacrylate))(HPVBEG) was synthesized via the combination of reversible addition-fragmentation chain-transfer(RAFT) polymerization and self-condensing vinyl polymerization(SCVP). Subsequently, the anticancer drug doxorubicin(DOX) was linked to HPVBEG via pH sensitive Schiff base bonds to form HPVBEG-g-DOX conjugates.Through aminolysis reaction, HPVBEG-g-DOX was coordinated with gold nanoparticles(GNP), resulting in the formation of HPVBEG-g-DOX/GNP complexes. In neutral condition, the HPVBEG-g-DOX/GNP complexes were stable, and DOX was bound to the surface of GNPs. Therefore, the SERS of DOX could be observed, while the fluorescence of DOX was quenched by GNPs. Under an acidic environment, DOX was released from the surface of GNPs with breakage of Schiff base bonds.Thus, the SERS signal of DOX was gradually reduced. Correspondingly, the fluorescence signal of DOX was enhanced.Through dual-modal SERS-fluorescence technique, the DOX delivery and release process was traced in tumor cells. Moreover,the viability of MCF-7 cells incubated with HPVBEG-g-DOX/GNP complexes was investigated by Cell Counting Kit-8(CCK-8) assay. The experimental results showed that HPVBEG-g-DOX/GNP complexes had similar proliferation inhibition effect compared with free DOX. Definitely, the dual-modal SERS-fluorescence complexes for tracing drug delivery and release will have promising prospects on tumor diagnosis and therapy. | Yuanyuan Zhuang Dali Wang Chunhui Yin Hongping Deng Mo Sun Lin He Yue Su Xinyuan Zhu | 2016 | Science China Chemistry2016，59，12： | 0 |

| 18 | Biocompatibility of Surface-Modified Biphasic Calcium Phosphate/Poly-L-Lactide Biocomposite in vitro and in vivo显示文摘The biocompatibility of surface-modified biphasic calcium phosphate (mBCP)/poly-L-Lactide (PLLA) biocomposite was investigated through a series of experiments in vitro and in vivo. Acute toxicity and short term systemic toxicity experiments revealed no toxicity of the materials. Hemolysis assay indicated the good blood compatibility of the composite. In cytotoxicity assay, L929 mouse fibroblasts could well differentiate and proliferate. Animal experiments in vivo were performed by implanting the materials into rabbits muscle for 8 weeks. The decreasing of inflammatory cells, the building of fibrous tissue layer as well as the growing of blood cells into materials indicated the nontoxicity of the composite. Based on the experiment results, surfacemodified BCP/PLLA biocomposite is proven to have superior biocompatibility, which would be a promising bone repairing material. | Weizhong Yang Guangfu Yin Dali Zhou Jianwen Gu Yadong Li Hujun Zhang | 2010 | Journal of Materials Science & Technology2010，26，8： | 0 |
| 19 | Characterization of ZnO Based Varistor Derived from Nano ZnO Powders and Ultrafine Dopants显示文摘Nanosized ZnO powders were prepared with a two-step precipitation method. The average size of ZnO particles was about 80 nm and their size distribution was narrow. Combining with ultrafine additive powders, ZnO base varistor was produced via an oxide mixing route. ZnO varistor derived from normal reagent grade starting materials was investigated for comparison purpose. Outstanding microstructure of the ZnO varistor derived from nanosize ZnO powders and ultrafine dopants was obtained: uniform distribution of fine ZnO grains (less than 3 microns), grain boundary and the dopant position. Higher varistor voltage (U=492 V/mm) and nonlinear coefficient (α=56.2) as well as lower leakage current (IL=1.5μA) were achieved. The better electrical properties were attributed to the uniform microstructure, which in turn led to stable and uniform potential barriers. Also this improved technique is more feasible for producing ZnO nanopowders and resulting varistor in large scales. | Weizhong YANG, Dali ZHOU, Guangfu YIN, Runsheng WANG and Yun ZHANG College of Material Science and Engineering, Sichuan University, Chengdu 610064, China | 2005 | Journal of Materials Science & Technology2005，21，2： | 0 |
| 20 | A general strategy for in situ assembly of light-up fluorophores via bioorthogonal Suzuki-Miyaura cross-coupling显示文摘Herein we presented a general strategy for in situ assembly of intramolecular charge-transfer(ICT)-based light-up fluorophores via bioorthogonal Suzuki-Miyaura cross-coupling reaction.By introducing iodo group at the appropriate position,five fluorophores with different scaffolds including naphthalimide,coumarin,naphthalene sulfonate,nitrobenzoxadiazole,and acetonaphthone,were designed as bioorthogonal multicolor fluorogenic probes,which could produce significant fluorescence enhancement and high fluorescence quantum yield after Suzuki-Miyaura reaction with aryl boronic acid or boronate.Manipulating the substituents andπscaffold in the fluorophores allows fine-tuning of their photophysical properties.With this strategy,we succeeded in peptide conjugation,no-wash fluorogenic protein labeling,and mitochondria-selective bioorthogonal imaging in live cells. | Xiang Li Hong Yang Yu Teng Yongcheng Wang Dali Yin Yulin Tian | 2022 | Chinese Chemical Letters2022，33，9： | 0 |
