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
2Mechanistic insights into the adsorption and bioactivity of fibronectin on surfaces with varying chemistries by a combination of experimental strategies and molecular simulations显示文摘Fibronectin(Fn)is significant to the performance of biomaterials,and the chemistry of biomaterial surface play important roles in Fn adsorption and subsequent cell behavior.However,the“molecular scale”mechanism is still unclear.Herein,we combined experimental strategies with molecular simulations to solve this problem.We prepared self-assembled monolayers with varying chemistries,i.e.,SAMs-CH3,SAMs-NH2,SAMs-COOH and SAMs-OH,and characterized Fn adsorption and cell behaviors on them.Next,Monte Carlo method and all-atom molecular dynamics simulations were employed to reveal the orientation/conformation of Fn on surfaces.We found that SAMs-CH3 strongly adsorbed Fn via hydrophobic interactions,but show poor bioactivity as the low exposure of RGD/PHSRN motifs and the deformation of Fn.SAMs-NH2 and SAMs-COOH could adsorb Fn efficiently via vdW interactions,electrostatic interactions,hydrogen bonds and salt bridges.Fn exhibited excellent bioactivity for cell adhesion,proliferation and osteogenic differentiation as high exposure of bioactive motifs on SAMs-NH2,or as the activation of other inferior cell-binding motifs on SAMs-COOH.SAMs-OH showed poor Fn adsorption as the water film.However,the adsorbed Fn displayed non-negligible bioactivity due to high exposure of PHSRN motif and large degree of protein flexibility.We believe that the revealed mechanism presents great potential to rationally design Fn-activating biomaterials.Lijing Hao Tianjie Li Lin Wang Xuetao Shi Yan Fan Chang Du Yingjun Wang 2021Bioactive Materials2021,6,10:3

4Origami meets electrospinning:a new strategy for 3D nanofiber scaffolds显示文摘Inspired by the constitution of things in the natural world,three-dimensional (3D)nanofiber scaffold/cells complex was constructed via the combination of electrospinning technology and origami techniques.The nanofiber boxes prepared by origami provided a limited space for the layer-by-layer nanofiber films,and the human fetal osteoblasts (hFOBs)seeded on the both sides of the nanofiber films were expected to facilitate the bonding,of the adjacent nanofiber films through the secretion of extracellular matrix.Specifically,the hFOBs presented 3D distribution in the nanofiber scaffold,and they can stretch across the gaps between the adjacent nanofiber films,forming the cell layers and filling the whole 3D nanofiber scaffold.Eventually,a 3D block composed of electrospun nanofiber scaffold and cells was obtained',which possesses potential applications in bone tissue engineering.Interestingly,we also created 3D nanofiber structures that range from simple forms to intricate architectures via origami,indicating that the combination of electrospinning technology and origami techniques is a feasible method for the 3D construction of tissue engineering scaffolds.Juqing Song Guanglin Zhu Huichang Gao Lin Wang Nanying Li Xuetao Shi Yingjun Wang 2018Bio-Design and Manufacturing2018,1,4:1
5Precise Thermoplastic Processing of Graphene Oxide Layered Solid by Polymer Intercalation显示文摘The processing capability is vital for the wide applications of materials to forge structures as-demand.Graphene-based macroscopic materials have shown excellent mechanical and functional properties.However,different from usual polymers and metals,graphene solids exhibit limited deformability and processibility for precise forming.Here,we present a precise thermoplastic forming of graphene materials by polymer intercalation from graphene oxide(GO)precursor.The intercalated polymer enables the thermoplasticity of GO solids by thermally activated motion of polymer chains.We detect a critical minimum containing of intercalated polymer that can expand the interlayer spacing exceeding 1.4 nm to activate thermoplasticity,which becomes the criteria for thermal plastic forming of GO solids.By thermoplastic forming,the flat GO-composite films are forged to Gaussian curved shapes and imprinted to have surface relief patterns with size precision down to 360 nm.The plastic-formed structures maintain the structural integration with outstanding electrical(3.07×10^(5) S m^(−1))and thermal conductivity(745.65 W m^(−1) K^(−1))after removal of polymers.The thermoplastic strategy greatly extends the forming capability of GO materials and other layered materials and promises versatile structural designs for more broad applications.Zeshen Li Fan Guo Kai Pang Jiahao Lin Qiang Gao Yance Chen Dan Chang Ya Wang Senping Liu Yi Han Yingjun Liu Zhen Xu Chao Gao 2022Nano-Micro Letters2022,14,1:1

9Macroscopic assembled graphene nanofilms based room temperature ultrafast mid-infrared photodetectors显示文摘Graphene with linear energy dispersion and weak electron-phonon interaction is highly anticipated to harvest hot electrons in a broad wavelength range.However,the limited absorption and serious backscattering of hot-electrons result in inadequate quantum yields,especially in the mid-infrared range.Here,we report a macroscopic assembled graphene(nMAG)nanofilm/silicon heterojunction for ultrafast mid-infrared photodetection.The assembled Schottky diode works in 1.5-4.0μm at room temperature with fast response(20-30 ns,rising time,4 mm2 window)and high detectivity(1.61011 to 1.9109 Jones from 1.5 to 4.0μm)under the pulsed laser,outperforming single-layer-graphene/silicon photodetectors by 2-8 orders.These performances are attributed to the greatly enhanced photo-thermionic effect of electrons in nMAG due to its high light absorption(~40%),long carrier relaxation time(~20 ps),low work function(4.52 eV),and suppressed carrier number fluctuation.The nMAG provides a long-range platform to understand the hot-carrier dynamics in bulk 2D materials,leading to broadband and ultrafast MIR active imaging devices at room temperature.Li Peng Lixiang Liu Sichao Du Srikrishna Chanakya Bodepudi Lingfei Li Wei Liu Runchen Lai Xiaoxue Cao Wenzhang Fang Yingjun Liu Xinyu Liu Jianhang Lv Muhammad Abid Junxue Liu Shengye Jin Kaifeng Wu Miao-Ling Lin Xin Cong Ping-Heng Tan Haiming Zhu Qihua Xiong Xiaomu Wang Weida Hu Xiangfeng Duan Bin Yu Zhen Xu Yang Xu Chao Gao 2022InfoMat2022,4,6:1
10Dissolved black carbon concentrations in suspended particulate matter from the Bohai Sea显示文摘Dissolved black carbon(DBC)includes the water-soluble component of black carbon and/or its degradation products.It is a hydrophobic organic compound due to its thick cyclic aromatic structure and can therefore be present as particulate DBC(PDBC)on suspended particulate matter or particulate organic matter.PDBC is not equivalent to particulate black carbon(PBC)and is thus often overlooked when researchers measure PBC in particulate matter using current conventional methods.Consequently,the amount of DBC in nature is likely underestimated in many studies and the reliability of current findings on the geochemical behavior of DBC is subject to challenge.In this study,we attempted to draw the solid-liquid partition coefficient(K_(d),PDBC/DBC)based on detailed data on PBC,DBC,particulate organic carbon,total suspended solids,dissolved polycyclic aromatic hydrocarbons,and particulate polycyclic aromatic hydrocarbons in the surface waters of the Bohai Sea.The obtained K_(d)was in the range of 0.018-0.072.Accordingly,the concentrations of PDBC were 1.637-6.449μg C L^(-1).The estimated inventory of PDBC on suspended particulate matter in the Bohai Sea was 2.049-8.194 Gg,which was lower than that of PBC(15.16 Gg)but of the same order of magnitude.These results indicate that PDBC is an important form of DBC in the Bohai Sea.Quantitative results of DBC fluxes between the dissolved and particulate phases will benefit our understanding of DBC transport and fates in the ocean.Chongtai CHEN Yin FANG Yingjun CHEN Tian LIN Fengchang WU 2023Science China Earth Sciences2023,66,5:0
11Whole-process optimization for industrial production of glucosamine sulfate sodium chloride based on QbD concept显示文摘The double salt of glucosamine sulfate sodium chloride(glucosamine-SP) is an important pharmaceuticals ingredient for healing osteoarthritis. However, the study about its industrial production is rarely documented, let alone the optimization over the whole process to produce glucosamine-SP using glucosamine hydrochloride and anhydrous sodium sulfate as synthetic raw materials. In order to improve the production efficiency, this study screened the process parameters based on the concept of quality by design(QbD), optimized 13 operational parameters related to reaction and separation in the process, and finally proposed the mixed dropping process. The reaction conditions for the preparation of glucosamineSP were found as follows: the molar ratio of anhydrous sodium sulfate to glucosamine hydrochloride is 0.42, the mass ratio of water to glucosamine hydrochloride is is 2.0, the reaction temperature is 50 ℃ and the reaction time is 1 h. Through step-by-step scaling up following QbD, the mixed dropping process was successfully applied to achieve a trial production of 200 kg products satisfying national quality standards.In all, the results of this study have high technical value and guiding significance for the industrial mass production of glucosamine-SP.Yingjun Lin 2023Chinese Journal of Chemical Engineering2023,54,2:0
12Up-regulation of miR-1245 by c-myc targets BRCA2 and impairs DNA repair显示文摘BRCA2,a clinical prognostic factor,is significantly up-regulated in mRNA level,while its protein expression is often decreased in sporadic breast cancer.However,how BRCA2 protein expressions are suppressed in these tumors remains unknown.In this study,we demonstrated that miR-1245 directly suppressed BRCA23′-UTR and translation,impaired homologous recombination(HR)-mediated repair,reduced DNA damage-induced Rad51 nuclear foci,and rendered cells hypersensitive to g-irradiation(IR),ul-timately inducing high chromosomal abnormalities in normal breast cells and breast cancer cells.Conversely,inhibiting miR-1245 in breast cancer cells enhanced BRCA2 levels and induced resistance to IR.Furthermore,we demonstrated that c-myc up-regulated miR-1245 expression via direct binding to the miR-1245 promoter,which led to down-regulation of BRCA2 and reduction in HR efficiency.Significantly,miR-1245 levels in primary breast tumors correlated with c-myc overexpression and BRCA2 suppression.These findings uncover a BRCA2 regulatory and signaling pathway in sporadic breast cancer and support a functionally and clinically relevant epigenetic mechanism in cancer pathogenesis.Libing Song Ting Dai Yingjun Xie Chanjuan Wang Chuyong Lin Zhiqiang Wu Zhe Ying Jueheng Wu Mengfeng Li Jun Li 2012Journal of Molecular Cell Biology2012,4,2:0

14Wrinkling modes of graphene oxide assembled on curved surfaces显示文摘Assembling two-dimensional(2D)sheets into macroscopic three-dimensional(3D)forms has created a promising material family with rich functionalities.Multiscale wrinkles are intrinsic features of 2D sheets in their 3D assembles.Therefore,the precise wrinkling modulation optimizes the transition of outstanding properties of 2D sheets to expected performances of assembled materials and dominates their fabrication process.The wrinkling evolution of 2D sheets assembling onto flat surfaces has been extensively understood,however,the wrinkling behaviors on the more generally curved surface still remain unclear.Here,we investigate the wrinkling behaviors of graphene oxide sheets assembled onto curved surfaces and reveal the selection rule of wrinkling modes that determined by the curvature mismatch between 2D sheets and target surfaces.We uncover that three wrinkling modes including isotropic cracked land,labyrinth,and anisotropic curtain phases,respectively emerge on flat,spherical,and cylindrical surfaces.A favorable description paradigm is offered to quantitatively measure the complex wrinkling patterns and assess the curvature mismatch constraint underlying the wrinkling mode selection.This research provides a general and quantitative description framework of wrinkling modulation of 2D materials such as high performance graphene fibers,and guides the precise fabrication of particles and functional coatings.Kaiwen Li Zhanpo Han Lidan Wang Jiaqing Wang Chuanwei Zhang Jiahao Lin Shiyu Luo Li Peng Wenzhang Fang Yingjun Liu Ziliang Wu Yeqiang Tan Chao Gao Zhen Xu 2023Nano Research2023,16,2:0
15Boosting wheat functional genomics via an indexed EMS mutant library of KN9204显示文摘A better understanding of wheat functional genomics can improve targeted breeding for better agronomic traits and environmental adaptation.However,the lack of gene-indexed mutants and the low transformation efficiency of wheat limit in-depth gene functional studies and genetic manipulation for breeding.In this study,we created a library for KN9204,a popular wheat variety in northern China,with a reference genome,transcriptome,and epigenome of different tissues,using ethyl methyl sulfonate(EMS)mutagenesis.This library contains a vast developmental diversity of critical tissues and transition stages.Exome capture sequencing of 2090 mutant lines using KN9204 genome-designed probes revealed that 98.79%of coding genes had mutations,and each line had an average of 1383 EMS-type SNPs.We identified new allelic variations for crucial agronomic trait-related genes such as Rht-D1,Q,TaTB1,and WFZP.We tested 100 lines with severemutations in 80 NAC transcription factors(TFs)under drought and salinity stress and identified 13 lines with altered sensitivity.Further analysis of three lines using transcriptome and chromatin accessibility data revealed hundreds of direct NAC targets with altered transcription patterns under salt or drought stress,including SNAC1,DREB2B,CML16,and ZFP182,factors known to respond to abiotic stress.Thus,we have generated and indexed a KN9204 EMS mutant library that can facilitate functional genomics research and offer resources for genetic manipulation of wheat.Dongzhi Wang Yongpeng Li Haojie Wang Yongxin Xu Yiman Yang Yuxin Zhou Zhongxu Chen Yuqing Zhou Lixuan Gui Yi Guo Chunjiang Zhou Wenqiang Tang Shuzhi Zheng Lei Wang Xiulin Guo Yingjun Zhang Fa Cui Xuelei Lin Yuling Jiao Yuehui He Junming Li Fei He Xigang Liu Jun Xiao 2023Plant Communications2023,4,4:0

17APOE interacts with ACE2 inhibitingg SARS-CoV-2 cellular entry and inflammation in COVID-19 patients显示文摘Apolipoprotein E(APOE)plays a pivotal role in lipid including cholesterol metabolism.The APOE 4(APOE4)allele is a major genetic risk factor for Alzheimer's and cardiovascular diseases.Although APOE has recently been associated with increased susceptibility to infections of several viruses,whether and how APOEand its isoforms affect SARS-CoV-2 infection remains unclear.Here,we show that serum concentrations of APOE correlate inversely with levels of cytokine/chemokine in 73 COVID-19 patients.Utilizing multiple protein interaction assays,we demonstrate that APOE3 and APOE4 interact with the SARS-CoV-2 receptor ACE2;and APOE/ACE2 interactions require zinc metallopeptidase domain of ACE2,a key docking site for SARS-CoV-2 Spike protein.In addition,immuno-imaging assays using confocal,super-resolution,and transmission electron microscopies reveal that both APOE3 and APOE4 reduce ACE2/Spikemediated viral entry into cells.Interestingly,while having a comparable binding affinity to ACE2,APOE4 inhibits viral entry to a lesser extent compared to APOE3,which is likely due to APOE4's more compact structure and smaller spatial obstacle to compete against Spike binding to ACE2.Furthermore,APOE e4 carriers clinically correlate with increased SARS-CoV-2 infection and elevated serum inflammatory factors in 142 COVID-19 patients assessed.Our study suggests a regulatory mechanism underlying SARS-CoV-2 infection through APOE interactions with ACE2,which may explain in part increased COVID-19 infection and disease severity in APOE e4 carriers.Hongsheng Zhang Lin Shao Zhihao Lin Quan-Xin Long Huilong Yuan Lujian Cai Guangtong Jiang Xiaoyi Guo Renzhi Yang Zepeng Zhang Bingchang Zhang Fan Liu Zhiyong Li Qilin Ma Yun-Wu Zhang Ai-Long Huang Zhanxiang Wang Yingjun Zhao Huaxi Xu 2022Signal Transduction and Targeted Therapy2022,7,9:0
18Microfossil evidence of rice cultivation on the Southeast China Coast 7500 years ago显示文摘Located on the southeast coast of China,Fujian is an important junction for the spread and migration of agriculture and populations from mainland Asia to Taiwan and the Island Southeast Asia.Research on the emergence of agriculture and its relationship with the regional environmental context is key to understanding the evolution of ancient human-land interactions in the coastal zone of China.This paper presents a detailed microfossil analysis of the Dapingding site,which is located in the lower reaches of the Min River on the southeast coast of China.We found a large number of phytoliths produced in rice stems and leaves from the cultural layers of this site,dated to 7,500 cal.a BP.In addition,we found rice husk impressions and rice phytoliths in the pottery sherds of these cultural layers.Among these phytoliths,rice bulliform phytoliths with≥9 fish-scale patterns indicating the degree of rice domestication,accounted for 44%.This percentage is much higher than the established standard for wild rice bulliform phytoliths with fish-scale patterns,suggesting that rice cultivation had already occurred on the southeast coast of China approximately 7,500 years ago.Subsequently,the starting time of agricultural activity on the southeast coast of China was pushed from 5,000 to 7,500 years ago.Comparing the regional history of sea level and coastline changes in the early to mid-Holocene,we suggest that the emergence of early rice cultivation in Southeast China was associated with high sea levels in the midHolocene and the last transgression in the Fuzhou Basin.The’Fuzhou Bay’,formed by the retreating coastline and transgression driven by high sea levels,may have provided a sea channel for the southward movement of northern rice farmers.Xinxin ZUO Jinqi DAI Wei WU Jianhui JIN Wei GE Yinping WANG Lin REN Yingjun LIN Yaoyao PEI Hui XIE 2022Science China Earth Sciences2022,65,11:0
