| 1 | Sequential fate-switches in stem-like cells drive the tumorigenic trajectory from human neural stem cells to malignant glioma显示文摘Glioblastoma(GBM)is an incurable and highly heterogeneous brain tumor,originating from human neural stem/progenitor cells(hNSCs/hNPCs)years ahead of diagnosis.Despite extensive efforts to characterize hNSCs and end-stage GBM at bulk and single-cell levels,the de novo gliomagenic path from hNSCs is largely unknown due to technical difficulties in early-stage sampling and preclinical modeling.Here,we established two highly penetrant hNSC-derived malignant glioma models,which resemble the histopathology and transcriptional heterogeneity of human GBM.Integrating time-series analyses of whole-exome sequencing,bulk and single-cell RNA-seq,we reconstructed gliomagenic trajectories,and identified a persistent NSC-like population at all stages of tumorigenesis.Through trajectory analyses and lineage tracing,we showed that tumor progression is primarily driven by multi-step transcriptional reprogramming and fate-switches in the NSC-like cells,which sequentially generate malignant heterogeneity and induce tumor phenotype transitions.We further uncovered stage-specific oncogenic cascades,and among the candidate genes we functionally validated C1QL1 as a new glioma-promoting factor.Importantly,the neurogenic-to-gliogenic switch in NSC-like cells marks an early stage characterized by a burst of oncogenic alterations,during which transient AP-1 inhibition is sufficient to inhibit gliomagenesis.Together,our results reveal previously undercharacterized molecular dynamics and fate choices driving de novo gliomagenesis from hNSCs,and provide a blueprint for potential early-stage treatment/diagnosis for GBM. | Xiaofei Wang Ran Zhou Yanzhen Xiong Lingling Zhou Xiang Yan Manli Wang Fan Li Chuanxing Xie Yiming Zhang Zongyao Huang Chaoqiong Ding Kaidou Shi Weida Li Yu Liu Zhongwei Cao Zhen-Ning Zhang Shengtao Zhou Chong Chen Yan Zhang Lu Chen Yuan Wang | 2021 | Cell Research2021,31,6: | 8 |
| 2 | Laser direct writing and characterizations of flexible piezoresistive sensors with microstructures显示文摘Functional materials with high viscosity and solid materials have received more and more attentions in flexible pressure sensors,which are inadequate in the most used molding method.Herein,laser direct writing(LDW)method is proposed to fabricate flexible piezoresistive sensors with microstructures on PDMS/MWCNTs composites with an 8%MWCNTs mass fraction.By controlling laser energy,microstructures with different geometries can be obtained,which significantly impacts the performances of the sensors.Subsequently,curved microcones with excellent performance are fabricated under parameters of f=40 kHz and v=150 mm·s^(-1).The sensor exhibits continuous multi-linear sensitivity,ultrahigh original sensitivity of 21.80%kPa^(-1),wide detection range of over 20 kPa,response/recovery time of~100 ms and good cycle stability for more than 1000 times.Besides,obvious resistance variation can be observed when tiny pressure(a peanut of 30 Pa)is applied.Finally,the flexible piezoresistive sensor can be applied for LED brightness controlling,pulse detection and voice recognition. | Chenying Zhang Wei Zhou Da Geng Cheng Bai Weida Li Songyue Chen Tao Luo Lifeng Qin Yu Xie | 2021 | Opto-Electronic Advances2021,4,4: | 7 |
| 3 | Roles of fishing and climate change in long-term fish species succession and population dynamics in the outer Beibu Gulf,South China Sea显示文摘A prevailing,controversial hypothesis is that fishing pressure has played a greater role than climatic and environmental drivers,in changing fish species succession and biomass fluctuation in the South China Sea(SCS).Based on otter trawl survey data from 1959 to 2010 in the outer Beibu Gulf(OBG),northern SCS,large seasonal and interannual variation is reported for fish species composition,the proportional abundances of dominant taxa,and fish biomass.Generalized additive models are developed to quantify relationships between fish biomass and the external factors of fishing pressure and climate change.Fishing pressure proved to be the main driver of sharp declines in demersal fish stocks,with high-value species being replaced by low-value ones over time.Abrupt decreases in fish biomass during the years of 1993 and 1998 correspond to El Nino events,with climate change possibly the main driver of proportional representation of pelagic species in fisheries trawl catch.The need to differentiate impacts of fishing and environmental drivers on fish species with different life history strategies is stressed to better understand fish community dynamics. | Xuehui Wang Yongsong Qiu Feiyan Du Weida Liu Dianrong Sun Xiao Chen Weiwen Yuan Yong Chen | 2019 | Acta Oceanologica Sinica2019,38,10: | 6 |
| 4 | Pristine PN junction toward atomic layer devices显示文摘In semiconductor manufacturing,PN junction is formed by introducing dopants to activate neighboring electron and hole conductance.To avoid structural distortion and failure,it generally requires the foreign dopants localize in the designated micro-areas.This,however,is challenging due to an inevitable interdiffusion process.Here we report a brand-new junction architecture,called'layer PN junction',that might break through such limit and help redefine the semiconductor device architecture.Different from all existing semiconductors,we find that a variety of van der Waals materials are doping themselves from n-to p-type conductance with an increasing/decreasing layer-number.It means the capability of constructing homogeneous PN junctions in monolayers'dimension/precision,with record high rectification-ratio(>10^(5))and low cut-off current(<1 pA).More importantly,it spawns intriguing functionalities,like gate-switchable-rectification and noise-signal decoupled avalanching.Findings disclosed here might open up a path to develop novel nanodevice applications,where the geometrical size becomes the only critical factor in tuning charge-carrier distribution and thus functionality. | Hui Xia Man Luo Wenjing Wang Hailu Wang Tianxin Li Zhen Wang Hangyu Xu Yue Chen Yong Zhou Fang Wang Runzhang Xie Peng Wang Weida Hu Wei Lu | 2022 | Light(Science & Applications)2022,11,7: | 4 |

| 6 | Tinea faciei in a newborn due toTrichophyton tonsurans显示文摘We report here the first case of neonatal tinea faciei caused by Trichophyton tonsurans in China's Mainland.The mother of the infant had tinea corpris and tinea capitis while the father had tinea incongnito.The infections in the parents were mycologically confirmed to be due to Trichophyton tonsurans.Ttinea faciei in the infant was cured after two-week topical use of amorolfine cream.The mother ceased breastfeeding and took oral terbinafine for 4 weeks.No recurrence was observed in the infant during 12 months of follow-up. | Meihua Fu Yiping Ge Wei Chen Suying Feng Xiaodong She Xiaofang Li Weida Liu | 2013 | The Journal of Biomedical Research2013,27,1: | 3 |
| 7 | A versatile photodetector assisted by photovoltaic and bolometric effects显示文摘The advent of low-dimensional materials with peculiar structure and superb band properties provides a new canonical form for the development of photodetectors.However,the limited exploitation of basic properties makes it difficult for devices to stand out.Here,we demonstrate a hybrid heterostructure with ultrathin vanadium dioxide film and molybdenum ditelluride nanoflake.Vanadium dioxide is a classical semiconductor with a narrow bandgap,a high temperature coefficient of resistance,and phase transformation.Molybdenum ditelluride,a typical two-dimensional material,is often used to construct optoelectronic devices.The heterostructure can realize three different functional modes:(i)the p-n junction exhibits ultrasensitive detection(450 nm-2μm)with a dark current down to 0.2 pA and a response time of 17μs,(ii)the Schottky junction works stably under extreme conditions such as a high temperature of 400 K,and(iii)the bolometer shows ultrabroad spectrum detection exceeding 10μm.The flexible switching between the three modes makes the heterostructure a potential candidate for next-generation photodetectors from visible to longwave infrared radiation(LWIR).This type of photodetector combines versatile detection modes,shedding light on the hybrid application of novel and traditional materials,and is a prototype of advanced optoelectronic devices. | Wei Jiang Tan Zheng Binmin Wu Hanxue Jiao Xudong Wang Yan Chen Xiaoyu Zhang Meng Peng Hailu Wang Tie Lin Hong Shen Jun Ge Weida Hu Xiaofeng Xu Xiangjian Meng Junhao Chu Jianlu Wang | 2020 | Light(Science & Applications)2020,9,1: | 3 |
| 8 | Visualization Research and Application of Water Quality Monitoring Data Based on ECharts显示文摘Water resources are one of the basic resources for human survival,and water protection has been becoming a major problem for countries around the world.However,most of the traditional water quality monitoring research work is still concerned with the collection of water quality indicators,and ignored the analysis of water quality monitoring data and its value.In this paper,by adopting Laravel and AdminTE framework,we introduced how to design and implement a water quality data visualization platform based on Baidu ECharts.Through the deployed water quality sensor,the collected water quality indicator data is transmitted to the big data processing platform that deployed on Tencent Cloud in real time through the 4G network.The collected monitoring data is analyzed,and the processing result is visualized by Baidu ECharts.The test results showed that the designed system could run well and will provide decision support for water resource protection. | Yifu Sheng Weida Chen Huan Wen Haijun Lin Jianjun Zhang | 2020 | Journal on Big Data2020,2,1: | 3 |

| 10 | Stoichiometric effect on electrical and near-infrared photodetection properties of full-composition-range GaAs1−xSbx nanowires显示文摘As one of the most important narrow bandgap ternary semiconductors, GaAs1−xSbx nanowires (NWs) have attracted extensive attention recently, due to the superior hole mobility and the tunable bandgap, which covers the whole near-infrared (NIR) region, for technological applications in next-generation high-performance electronics and NIR photodetection. However, it is still a challenge to the synthesis of high-quality GaAs1−xSbx NWs across the entire range of composition, resulting in the lack of correlation investigation among stoichiometry, microstructure, electronics, and NIR photodetection. Here, we demonstrate the success growth of high-quality GaAs1−xSbx NWs with full composition range by adopting a simple and low-cost surfactant-assisted solid source chemical vapor deposition method. All of the as-prepared NWs are uniform, smooth, and straight, without any phase segregation in all stoichiometric compositions. The lattice constants of each NW composition have been well correlated with the chemical stoichiometry and confirmed by high-resolution transmission electron microscopy, X-ray diffraction, and Raman spectrum. Moreover, with the increase of Sb concentration, the hole mobility of the as-fabricated field-effect-transistors and the responsivity and detectivity of the as-fabricated NIR photodetectors increase accordingly. All the results suggest a careful stoichiometric design is required for achieving optimal NW device performances. | Jiamin Sun Mingming Han Meng Peng Lei Zhang Dong Liu Chengcheng Miao Jiafu Ye Zhiyong Pang Longbing He Hailu Wang Qing Li Peng Wang Lin Wang Xiaoshuang Chen Chongxin Shan Litao Sun Weida Hu Zai-xing Yang | 2021 | Nano Research2021,14,11: | 1 |

| 12 | A gate-free MoS2 phototransistor assisted by ferroelectrics显示文摘During the past decades,transition metal dichalcogenides(TMDs) have received special focus for their unique properties in photoelectric detection.As one important member of TMDs,MoS2 has been made into photodetector purely or combined with other materials,such as graphene,ionic liquid,and ferroelectric materials.Here,we report a gate-free MoS2 phototransistor combined with organic ferroelectric material poly(vinylidene fluoride-trifluoroethylene)(P(VDF-TrFE)).In this device,the remnant polarization field in P(VDF-TrFE) is obtained from the piezoelectric force microscope(PFM) probe with a positive or negative bias,which can turn the dipoles from disorder to be the same direction.Then,the MoS2 channel can be maintained at an accumulated state with downward polarization field modulation and a depleted state with upward polarization field modulation.Moreover,the P(VDF-TrFE) segregates MoS2 from oxygen and water molecules around surroundings,which enables a cleaner surface state.As a photodetector,an ultra-low dark current of 10^–11 A,on/off ration of more than 10^4 and a fast photoresponse time of 120 μs are achieved.This work provides a new method to make high-performance phototransistors assisted by the ferroelectric domain which can operate without a gate electrode and demonstrates great potential for ultra-low power consumption applications. | Shuaiqin Wu Guangjian Wu Xudong Wang Yan Chen Tie Lin Hong Shen Weida Hu Xiangjian Meng Jianlu Wang Junhao Chu | 2019 | Journal of Semiconductors2019,40,9: | 1 |

| 15 | Pectin modulates intestinal immunity in a pig model via regulating the gut microbiota-derived tryptophan metabolite-AhR-IL22 pathway显示文摘Background Pectin is a heteropolysaccharide that acts as an intestinal immunomodulator,promoting intestinal development and regulating intestinal flora in the gut.However,the relevant mechanisms remain obscure.In this study,pigs were fed a corn-soybean meal-based diet supplemented with either 5%microcrystalline cellulose(MCC)or 5%pectin for 3 weeks,to investigate the metabolites and anti-inflammatory properties of the jejunum.Result The results showed that dietary pectin supplementation improved intestinal integrity(Claudin-1,Occludin)and inflammatory response[interleukin(IL)-10],and the expression of proinflammatory cytokines(IL-1β,IL-6,IL-8,TNF-α)was down-regulated in the jejunum.Moreover,pectin supplementation altered the jejunal microbiome and tryptophan-related metabolites in piglets.Pectin specifically increased the abundance of Lactococcus,Enterococcus,and the microbiota-derived metabolites(skatole(ST),3-indoleacetic acid(IAA),3-indolepropionic acid(IPA),5-hydroxyindole-3-acetic acid(HIAA),and tryptamine(Tpm)),which activated the aryl hydrocarbon receptor(AhR)pathway.AhR activation modulates IL-22 and its downstream pathways.Correlation analysis revealed the potential relationship between metabolites and intestinal morphology,intestinal gene expression,and cytokine levels.Conclusion In conclusion,these results indicated that pectin inhibits the inflammatory response by enhancing the AhR-IL22-signal transducer and activator of transcription 3 signaling pathway,which is activated through tryptophan metabolites. | Guoqi Dang Xiaobin Wen Ruqing Zhong Weida Wu Shanlong Tang Chong Li Bao Yi Liang Chen Hongfu Zhang Martine Schroyen | 2023 | Journal of Animal Science and Biotechnology2023,14,4: | 1 |
| 16 | Significant variations in alternative splicing patterns and expression profiles between human-mouse orthologs in early embryos显示文摘Human and mouse orthologs are expected to have similar biological functions; however, many discrepancies have also been reported. We systematically compared human and mouse orthologs in terms of alternative splicing patterns and expression profiles. Human-mouse orthologs are divergent in alternative splicing, as human orthologs could generally encode more isoforms than their mouse orthologs. In early embryos, exon skipping is far more common with human orthologs, whereas constitutive exons are more prevalent with mouse orthologs. This may correlate with divergence in expression of splicing regulators. Orthologous expression similarities are different in distinct embryonic stages, with the highest in morula. Expression differences for orthologous transcription factor genes could play an important role in orthologous expression discordance. We further detected largely orthologous divergence in differential expression between distinct embryonic stages. Collectively, our study uncovers significant orthologous divergence from multiple aspects, which may result in functional differences and dynamics between human-mouse orthologs during embryonic development. | Geng Chen Jiwei Chen Jianmin Yang Long Chen Xiongfei Qu Caiping Shi Baitang Ning Leming Shi Weida Tong Yongxiang Zhao Meixia Zhang Tieliu Shi | 2017 | Science China(Life Sciences)2017,60,2: | 1 |

| 18 | Sequencing XMET genes to promote genotype-guided risk assessment and precision medicine显示文摘High-throughput next generation sequencing (NGS) is a shotgun approach applied in a parallel fashion by which the genome is fragmented and sequenced through small pieces and then analyzed either by aligning to a known reference genome or by de novo assembly without reference genome.This technology has led researchers to conduct an explosion of sequencing related projects in multidisciplinary fields of science.However,due to the limitations of sequencing-based chemistry,length of sequencing reads and the complexity of genes,it is difficult to determine the sequences of some portions of the human genome,leaving gaps in genomic data that frustrate further analysis.Particularly,some complex genes are difficult to be accurately sequenced or mapped because they contain high GC-content and/or low complexity regions,and complicated pseudogenes,such as the genes encoding xenobiotic metabolizing enzymes and transporters (XMETs).The genetic variants in XMET genes are critical to predicate interindividual variability in drug efficacy,drug safety and susceptibility to environmental toxicity.We summarized and discussed challenges,wet-lab methods,and bioinformatics algorithms in sequencing 'complex' XMET genes,which may provide insightful information in the application of NGS technology for implementation in toxicogenomics and pharmacogenomics. | Yaqiong Jin Geng Chen Wenming Xiao Huixiao Hong Joshua Xu Yongli Guo Wenzhong Xiao Tieliu Shi Leming Shi Weida Tong Baitang Ning | 2019 | Science China(Life Sciences)2019,62,7: | 1 |

| 20 | QuaPra: Efficient transcript assembly and quantification using quadratic programming with Apriori algorithm显示文摘RNA sequencing(RNA-seq) has greatly facilitated the exploring of transcriptome landscape for diverse organisms.However,transcriptome reconstruction is still challenging due to various limitations of current tools and sequencing technologies.Here,we introduce an efficient tool,QuaPra(Quadratic Programming combined with Apriori),for accurate transcriptome assembly and quantification.QuaPra could detect at least 26.5% more low abundance(0.1–1 FPKM) transcripts with over 2.7% increase of sensitivity and precision on simulated data compared to other currently popular tools.Moreover,around one-quarter more known transcripts were correctly assembled by QuaPra than other assemblers on real sequencing data.QuaPra is freely available at http://gffzz964817d90372402ah00o50u50ffuo6nfw.ffgz.tsg.suse.edu.cn/QuaPra/. | Xiangjun Ji Weida Tong Baitang Ning Christopher E.
