1Potentiating CD8^(+) T cell antitumor activity by inhibiting PCSK9 to promote LDLR-mediated TCR recycling and signaling显示文摘Metabolic regulation has been proven to play a critical role in T cell antitumor immunity.However,cholesterol metabolism as a key component of this regulation remains largely unexplored.Herein,we found that the low-density lipoprotein receptor(LDLR),which has been previously identified as a transporter for cholesterol,plays a pivotal role in regulating CD8+T cell antitumor activity.Besides the involvement of cholesterol uptake which is mediated by LDLR in T cell priming and clonal expansion,we also found a non-canonical function of LDLR in CD8+T cells:LDLR interacts with the T-cell receptor(TCR)complex and regulates TCR recycling and signaling,thus facilitating the effector function of cytotoxic T-lymphocytes(CTLs).Furthermore,we found that the tumor microenvironment(TME)downregulates CD8+T cell LDLR level and TCR signaling via tumor cell-derived proprotein convertase subtilisin/kexin type 9(PCSK9)which binds to LDLR and prevents the recycling of LDLR and TCR to the plasma membrane thus inhibits the effector function of CTLs.Moreover,genetic deletion or pharmacological inhibition of PCSK9 in tumor cells can enhance the antitumor activity of CD8+T cells by alleviating the suppressive effect on CD8+T cells and consequently inhibit tumor progression.While previously established as a hypercholesterolemia target,this study highlights PCSK9/LDLR as a potential target for cancer immunotherapy as well.Juanjuan Yuan Ting Cai Xiaojun Zheng Yangzi Ren Jingwen Qi Xiaofei Lu Huihui Chen Huizhen Lin Zijie Chen Mengnan Liu Shangwen He Qijun Chen Siyang Feng Yingjun Wu Zhenhai Zhang Yanqing Ding Wei Yang 2021Protein & Cell2021,12,4:12
2Crystalline behaviors and phase transition during the manufacture of fine denier PA6 fibers显示文摘Recently we have successfully produced fine denier PA6 fibers by using additives containing lanthanide compounds.Meanwhile,crystallization and phase transition of PA6 fibers during spinning and drawing processes were investigated.During the spinning process,β phase crystal could be obtained in as-spun PA6 fibers which were produced with relatively high melt draw ratio,while γ phase crystal predominated when the melt draw ratio was relatively low.β phase crystal,whose behaviors are similar with those of γ phase by FT-IR and XRD characterization,could be transformed to α form easily when PA6 fibers are immersed in boiling water.However,γ phase crystal of PA6 remains unchanged in boiling water.Thus,β and γ phase crystals of PA6 can be differentiated by the crystalline behaviors of PA6 fibers after treatment in boiling water.Further experiments demonstrate that the β phase can also be produced during a drawing process where a phase transformation from γ to α occurs.In other words,β phase may act as an intermediate state during the phase transformation.ZHANG ChengFeng LIU YuHai LIU ShaoXuan LI HuiZhen HUANG Kun PAN QingHua HUA XiaoHui HAO ChaoWei MA QingFang LV ChangYou LI WeiHong YANG ZhanLan ZHAO Ying WANG DuJin LAI GuoQiao JIANG JianXiong XU YiZhuang WU JinGuang 2009Science China Chemistry2009,52,11:4
3The Fibrillin-1/VEGFR2/STAT2 signaling axis promotes chemoresistance via modulating glycolysis and angiogenesis in ovarian cancer organoids and cells显示文摘Background:Chemotherapy resistance is a primary reason of ovarian cancer therapy failure;hence it is important to investigate the underlying mechanisms of chemotherapy resistance and develop novel potential therapeutic targets.Methods:RNA sequencing of cisplatin-resistant and sensitive(chemoresis-tant and chemosensitive,respectively)ovarian cancer organoids was performed,followed by detection of the expression level of fibrillin-1(FBN1)in organoids and clinical specimens of ovarian cancer.Subsequently,glucose metabolism,angiogenesis,and chemosensitivity were analyzed in structural glycoprotein FBNl-knockout cisplatin-resistant ovarian cancer organoids and cell lines.To gain insights into the specific functions and mechanisms of action of FBN1 in ovarian cancer,immunoprecipitation,silver nitrate staining,mass spectrometry,immunofluorescence,Western blotting,and Forister resonance energy transfer-fluorescence lifetime imaging analyses were performed,followed by in vivo assays using vertebrate model systems of nude mice and zebrafish.Results:FBN1 expression was significantly enhanced in cisplatin-resistant ovar-ian cancer organoids and tissues,indicating that FBNI might be a key factor in chemoresistance of ovarian cancer.We also discovered that FBN1 sustained the energy stress and induced angiogenesis in vitro and in vivo,which promoted the cisplatin-resistance of ovarian cancer.Knockout of FBN1 combined with treat-ment of the antiangiogenic drug apatinib improved the cisplatin-sensitivity of ovarian cancer cells.Mechanistically,FBN1 mediated the phosphorylation of vascular endothelial growth factor receptor 2(VEGFR2)at the Tyrl054 residue,which activated its downstream focal adhesion kinase(FAK)/protein kinase B(PKB or AKT)pathway,induced the phosphorylation of signal transducer and activator of transcription 2(STAT2)at the tyrosine residue 690(Tyr690),pro-moted the nuclear translocation of STAT2,and ultimately altered the expression of genes associated with STAT2-mediated angiogenesis and glycolysis.Conclusions:The FBN1/VEGFR2/STAT2 signaling axis may induce chemore-sistance of ovarian cancer cells by participating in the process of glycolysis and angiogenesis.The present study suggested a novel FBNl-targeted therapy and/or combination of FBN1 inhibition and antiangiogenic drug for treating ovarian cancer.Ziliang Wang Wei Chen Ling Zuo Midie Xu Yong Wu Jiami Huang Xu Zhang Yongheng Li Jing Wang Jing Chen Husheng Wang Huizhen Sun 2022Cancer Communications2022,42,3:3
4A photosensitizer-loaded zinc oxide-polydopamine core-shell nanotherapeutic agent for photodynamic and photothermal synergistic therapy of cancer cells显示文摘In clinical cancer research,it is quite promising to develop multimodal synergistic therapeutic strategies.Photodynamic and photothermal synergistic therapy is a very desirable multimodal therapy strategy.Herein,we report a facile and simple method to construct a nanotherapeutic agent for photodynamic and photothermal therapy.This nanotherapeutic agent(ZnO@Ce6-PDA)is composed of a ZnO nanoparticle core,an interlayer of photosensitizer chlorin e6(Ce6)and an outer layer of polydopamine(PDA).Due to the existence of Ce6,the ZnO@Ce6-PDA can efficiently generate singlet oxygen(1O2)under 660 nm laser irradiation.Moreover,the ZnO@Ce6-PDA can serve as a photothermal agent,because of the excellent photothermal conversion efficiency of the PDA coating layer in the presence of 780 nm laser.Experiment results demonstrated that the designed nanotherapeutic agent had outstanding phototoxicity upon the combination of laser irradiation at 660 and 780 nm.Thus,our work proves that the ZnO@Ce6-PDA is a promising photodynamic/photothermal dual-modal nanotherapeutic agent for enhanced cancer therapy.Ri Wu Huizhen Wang Luo Hai Tianzheng Wang Min Hou Dinggeng He Xiaoxiao He Kemin Wang 2020Chinese Chemical Letters2020,31,1:3
5Ultrabroadband and multiband infrared/terahertz photodetectors with high sensitivity显示文摘Broadband response is pursued in both infrared(IR)and terahertz(THz)detection technologies,which find their applications in both terrestrial and astronomical realms.Herein,we report an ultrabroadband and multiband IR/THz detector based on blocked-impurity-band detecting principle.The detectors are prepared by implanting phosphorus into germanium(Ge:P),where photoresponses with a P impurity band,a self-interstitial defect band,and a vacancy-P(V-P)pair defect band are realized simultaneously.The response spectra of the detectors show ultrabroad and dual response bands in a range of 3-28μm(IR band)and 40-165μm(THz band),respectively.Additionally,a tiny mid-IR(MIR)band within 3-4.2μm is embedded in the IR band.The THz band arises from the P impurity band,whereas the IR and the MIR bands are ascribed to the two defect bands.At150 m V and 4.5 K,the peak detectivities of the three bands are obtained as 2.9×10^(12) Jones(at 3.9μm),6.8×10^(12) Jones(at 16.3μm),and 9.9×10^(12) Jones(at 116.5μm),respectively.The impressive coverage andsensitivity of the detectors are promising for applications in IR and THz detection technologies.JIAQI ZHU HE ZHU MENGJUAN LIU YAO WANG HANLUN XU NASIR ALI HUIYONG DENG ZHIYONG TAN JUNCHENG CAO NING DAI HUIZHEN WU 2021Photonics Research2021,9,11:2
6Performance-enhanced and cost-effective triboelectric nanogenerator based on stretchable electrode for wearable SpO2 monitoring显示文摘Recently,stretchable and wearable health monitoring equipment has greatly improved human’s daily life,which sets higher demands for portable power source in stretchability,sustainability,and biocompatibility.In this work,we proposed a stretchable triboelectric nanogenerator(TENG)based on stretchable poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS)/porous carbon hybrid for oxyhemoglobin saturation(SpO2)monitoring.To combine advantages of carbon material for its high conductivity and organic electrode for its high stretchability,we spin-coated a solution of PEDOT:PSS/porous carbon onto a plasma-treated pre-stretched Ecoflex film to fabricate a stretchable electrode with rough surface.Due to its roughness and high potential difference with the dielectric material,the stretchable-electrode-based TENG exhibited better performance compared to the pristine TENG based on carbon or PEDOT:PSS material.The output voltage and current reached up to 51.5 V and 13.2μA as the carbon concentration increased.More importantly,the performance further increased under large strain(100%)which is suitable for wearable systems.Finally,the device demonstrated its application potential for powering a flexible blood oxygen monitor.This simple and cost-effective method can enhance the stretchability and stability of organic/inorganic electrode-based TENG,which paves the development of high-performance stretchable TENG.Huamin Chen Wei Yang Cheng Zhang Mingqiang Wu Wenjie Li Yuxiao Zou Longfeng Lv Hualiang Yu Huizhen Ke Ruping Liu Yun Xu Jun Wang Zhou Li 2022Nano Research2022,15,3:2

8Programmed death ligand-1 regulates angiogenesis and metastasis by participating in the c-JUN/VEGFR2 signaling axis in ovarian cancer显示文摘Background:Although programmed cell death-ligand 1(PD-L1)plays a wellknown function in immune checkpoint response by interacting with programmed cell death-1(PD-1),the cell-intrinsic role of PD-L1 in tumors is still unclear.Here,we explored the molecular regulatory mechanism of PD-L1 in the progression and metastasis of ovarian cancer.Methods:Immunohistochemistry of benign tissues and ovarian cancer samples was performed,followed by migration,invasion,and angiogenesis assays in PDL1-knockdown ovarian cancer cells.Immunoprecipitation,mass spectrometry,and chromatin immunoprecipitation were conducted along with zebrafish and mouse experiments to explore the specific functions and mechanisms of PD-L1 in ovarian cancer.Results:Our results showed that PD-L1 induced angiogenesis,which further promoted cell migration and invasion in vitro and in vivo of ovarian cancer.Mechanistically,PD-L1 was identified to directly interact with vascular endothelial growth factor receptor-2(VEGFR2)and then activated the FAK/AKT pathway,which further induced angiogenesis and tumor progression,leading to poor prognosis of ovarian cancer patients.Meanwhile,PD-L1 was found to be regulated by the oncogenic transcription factor c-JUN at the transcriptional level,which enhanced the expression of PD-L1 in ovarian cancer.Furthermore,we demonstrated that PD-L1 inhibitor durvalumab,combined with the antiangiogenic drug,apatinib,could enhance the effect of anti-angiogenesis and the inhibition of cell migration and invasion.Conclusion:Our results demonstrated that PD-L1 promoted the angiogenesis and metastasis of ovarian cancer by participating in the c-JUN/VEGFR2 signaling axis,suggesting that the combination of PD-L1 inhibitor and antiangiogenic drugs may be considered as a potential therapeutic approach for ovarian cancer patients.Yufei Yang Lingfang Xia Yong Wu Hongyu Zhou Xin Chen Haoran Li Midie Xu Zihao Qi Ziliang Wang Huizhen Sun Xi Cheng 2021Cancer Communications2021,41,6:1

15Photodynamic Therapy for Advanced Gastric Cancer: A Case Report显示文摘Background and Study Aims:To observe the efficacy of photodynamic therapy in patients with advanced gastric cancer and analyze the reasons affecting the efficacy.Methods:In this paper,a patient with advanced gastric cancer in our hospital was selected.HoPorfin is used as a photosensitizer and photodynamic therapy was performed 48 hours and 72 hours later.Results:One month after the photodynamic treatment,the patient came to our hospital to reexamine the gastroscope.Through the comparison of gastroscopy before and after the photodynamic treatment,the gastric cancer lesion of the patient after the photodynamic treatment was not significantly smaller than before,and the effect of photodynamic treatment was not ideal.Conclusion:The four reasons for the unsatisfactory effect:individual differences of patients,photosensitizer,light source and oxygen.Hongyan Zhang Lule Wu Xiaoxiong Hu Jianwen Sheng Yuwen Wu Huizhen Fan 2021Journal of Clinical and Nursing Research2021,5,2:0
16Sustainable development index of shale gas exploitation in China, the UK, and the US显示文摘While shale gas could complement the world's natural gas supply,its environmental tradeoffs and sustainability potential should be cautiously assessed before using it to satisfy future energy needs.Shale gas development in China is still in its infancy but has been progressing by the Central Government at a fast pace nowadays.Advanced experience from North America would greatly benefit sustainable design and decision-making for energy development in China.However,the lack of consistency concerning internal and external parameters among previous investigations does not allow an integrated impact comparison among shale gas-rich countries.Herein,we applied a meta-analysis to harmonize environmental tradeoff data through a comprehensive literature review.Greenhouse gas emission,water consumption,and energy demand were selected as environmental tradeoff indicators during shale gas production.Data harmonization suggested that environmental tradeoffs ranged from 5.6 to 37.4 g CO_(2)-eq,11.0-119.7 mL water,and 0.027-0.127 MJ energy to produce 1 MJ shale gas worldwide.Furthermore,sustainable development indexes(SDIs)for shale gas exploitation in China were analyzed and compared to the United States and the United Kingdom by considering environment,economy,and social demand through an analytic hierarchy process.The United States and China elicit higher SDIs than the United Kingdom,indicating higher feasibility for shale gas exploitation.Although China has relatively low scores in the environmental aspect,large reservoirs and high future market demand make Chinese shale gas favorable in the social demand aspect.Region-specific SDI characteristics identified among representative countries could improve the sustainability potential of regional development and global energy supply.Liang Li Fan Wu Yuanyu Cao Fei Cheng Dali Wang Huizhen Li Zhiqiang Yu Jing You 2022Environmental Science and Ecotechnology2022,,4:0
17Robust Carbon-Carbon Cleavage in Lignin to Produce Phenol and Cyclohexanone显示文摘The challenge of breaking 5-5'bonds in lignin,attributed to their high bonding energy,has prompted the development of a new transformation pathway.Biphenyl,an important model compound for lignin,contains these 5-5'bonds,making it crucial to devise a strategy for their cleavage in lignin transformation.This study introduces a novel method for transforming biphenyl,involving selective hydrogenation to cyclohexylbenzene by Ni/SiO2 catalyst,followed by its oxidation to phenol and cyclohexanone through a radical mechanism.Results demonstrate that the catalysts with small particles have strong catalytic activity,while there is little difference in selectivity.The reason for the high selectivity of cyclohexylbenzene is due to the limited adsorption of cyclohexylbenzene on Ni/SiO2.This work presents a fresh approach to breaking resilient C-C bonds in lignin.WANG Lulin CHENG Xiaomeng DONG Minghua LUAN Sen WU Yuxuan HAN Buxing LIU Huizhen 2024Chemical Research in Chinese Universities2024,40,1:0
18Co-Ru alloy nanoparticles decorated onto two-dimensional nitrogen doped carbon nanosheets towards hydrogen/oxygen evolution reaction and oxygen reduction reaction显示文摘Constructing highly-efficient electrocatalysts toward hydrogen evolution reaction(HER)/oxygen evolution reaction(OER)/oxygen reduction reaction(ORR)with excellent stability is quite important for the development of renewable energy-related applications.Herein,Co-Ru based compounds supported on nitrogen doped two-dimensional(2D)carbon nanosheets(NCN)are developed via one step pyrolysis procedure(Co-Ru/NCN)for HER/ORR and following low-temperature oxidation process(Co-Ru@RuO_(x)/NCN)for OER.The specific 2D morphology guarantees abundant active sites exposure.Furthermore,the synergistic effects arising from the interaction between Co and Ru are crucial in enhancing the catalytic performance.Thus,the resulting Co-Ru/NCN shows remarkable electrocatalytic performance for HER(70 mV at 10 mA cm^(-2))in 1 M KOH and ORR(half-wave potential E_(1/2)=0.81 V)in 0.1 M KOH.Especially,the Co-Ru@RuO_(x)/NCN obtained by oxidation exhibits splendid OER performance in both acid(230 mV at 10 mA cm^(-2))and alkaline media(270 mV at 10 mA cm^(-2))coupled with excellent stability.Consequently,the fabricated two-electrode water-splitting device exhibits excellent performance in both acidic and alkaline environments.This research provides a promising avenue for the advancement of multifunctional nanomaterials.Huizhen Wang Pengfei Yang Xiaoyuan Sun Weiping Xiao Xinping Wang Minge Tian Guangrui Xu Zhenjiang Li Yubing Zhang Fusheng Liu Lei Wang Zexing Wu 2023Journal of Energy Chemistry2023,,12:0
19Reversal Efficacy of SDZ-PSC833 and Verapamil on Drug-Resistant Human Cervical Carcinoma Cells Line显示文摘This article discusses the characteristics of the drugresistant human cervical carcinoma cell line HeLa/MMC and investigates reversal effect of SDZ-PSC833(PSC833) and Verapamil (Ver) upon HeLa/MMC. Relative content of cell DNA detection, H^3-TdR incorporation test and drug-resistance have been experimented, meanwhile a tumor transplant model in the nude mice for Hela/MMC has been established. Then the volume of cancer, tumor weight, curve line of growing up in tumor -bearing nude mouse and its morphological variation of carcinoma organism are observed to evaluate the reversal effect of PSC833 and VER. It has been found that: ① Compared with HeLa cells,subline HeLa/ MMC Cells' drug-resistant capability against Mitomycin(MMC) or cisplatin(DDP) is as 5.02 folds or 2 folds as that of the former, respectively. The Hela/MMC cell line has characteristics of multi-drug resistance and stronger multiplication; ② PSC833 and VER can reverse resistance of HeLa/MMC to Mitomycin in vivo.PSC833 will be a better candidate for reversing multidrug resistant than verapamil in clinic application.CHEN Hong CHEN Huizhen WU Xufeng LIU Shiquan YANG Qingyi 2007Wuhan University Journal of Natural Sciences2007,12,2:0
20Electrochemical capacitance-voltage characterization of plasma-doped ultra-shallow junctions显示文摘Ultra-shallow Si p^(+)n junctions formed by plasma doping are characterized by electrochemical capacitance-voltage(ECV).By comparing ECV results with those of secondary ion mass spectroscopy(SIMS),it is found that the dopant concentration profiles in heavily-doped p+layer as well as junction depths measured by ECV are in good agreement with those measured by SIMS.However,the ECV measurement of dopant concentration in the underlying lightly doped n-type substrate is significantly influenced by the upper heavily-doped layer.The ECV technique is also easy to control and reproduce.The ECV results of ultra-shallow junctions(USJ)formed by plasma doping followed by different annealing processes show that ECV is capable of reliably characterizing a Si USJ with junction depth as low as 10 nm,and dopant concentration up to 10^(21) cm^(-3).Also,its depth resolution can be as fine as 1 nm.Therefore,it shows great potential in application for characterizing USJ in the sub-65 nm technology node CMOS devices.Huizhen WU Guoping RU Yonggang ZHANG Chengguo JIN Bunji MIZUNO Yulong JIANG Xinping QU Bingzong LI 2008Frontiers of Electrical and Electronic Engineering in China2008,3,1:0
