| 1 | Wnt/b-catenin signaling plays an ever-expanding role in stem cell self-renewal,tumorigenesis and cancer chemoresistance显示文摘Wnt signaling transduces evolutionarily conserved pathways which play important roles in initiating and regulating a diverse range of cellular activities,including cell proliferation,calcium homeostasis,and cell polarity.The role of Wnt signaling in controlling cell proliferation and stem cell self-renewal is primarily carried out through the canonical pathway,which is the best-characterized the multiple Wnt signaling branches.The past 10 years has seen a rapid expansion in our understanding of the complexity of this pathway,as many new components of Wnt signaling have been identified and linked to signaling regulation,stem cell functions,and adult tissue homeostasis.Additionally,a substantial body of evidence links Wnt signaling to tumorigenesis of cancer types and implicates it in the development of cancer drug resistance.Thus,a better understanding of the mechanisms by which dysregulation of Wnt signaling precedes the development and progression of human cancer may hasten the development of pathway inhibitors to augment current therapy.This review summarizes and synthesizes our current knowledge of the canonical Wnt pathway in development and disease.We begin with an overview of the components of the canonical Wnt signaling pathway and delve into the role this pathway has been shown to play in stemness,tumorigenesis,and cancer drug resistance.Ultimately,we hope to present an organized collection of evidence implicating Wnt signaling in tumorigenesis and chemoresistance to facilitate the pursuit of Wnt pathway modulators that may improve outcomes of cancers in which Wnt signaling contributes to aggressive disease and/or treatment resistance. | Maryam K.Mohammed Connie Shao Jing Wang Qiang Wei Xin Wang Zachary Collier Shengli Tang Hao Liu Fugui Zhang Jiayi Huang Dan Guo Minpeng Lu Feng Liu Jianxiang Liu Chao Ma Lewis L.Shi Aravind Athiviraham Tong-Chuan He Michael J.Lee | 2016 | Genes & Diseases2016,3,1: | 70 |

| 3 | On the combined effect of soil fertility and topography on tree growth in subtropical forest ecosystems—a study from SE China显示文摘Aims The aim of our research was to understand small-scale effects of topography and soil fertility on tree growth in a forest biodiversity and ecosystem functioning(BEF)experiment in subtropical SE China.Methods Geomorphometric terrain analyses were carried out at a spatial resolution of 5×5 m.Soil samples of different depth increments and data on tree height were collected from a total of 566 plots(667 m2 each).The soils were analyzed for carbon(soil organic carbon[SOC]),nitrogen,acidity,cation exchange capacity(CEC),exchangeable cations and base saturation as soil fertility attributes.All plots were classified into geomorphological units.Analyses of variance and linear regressions were applied to all terrain,soil fertility and tree growth attributes.Important Findings In general,young and shallow soils and relatively small differences in stable soil properties suggest that soil erosion has truncated the soils to a large extent over the whole area of the experiment.This explains the concurrently increasing CEC and SOC stocks downslope,in hollows and in valleys.However,colluvial,carbon-rich sediments are missing widely due to the convexity of the footslopes caused by uplift and removal of eroded sediments by adjacent waterways.The results showed that soil fertility is mainly influenced by topography.Monte-Carlo flow accumulation(MCCA),curvature,slope and aspect significantly affected soil fertility.Furthermore,soil fertility was affected by the different geomorphological positions on the experimental sites with ridge and spur positions showing lower exchangeable base cation contents,especially potassium(K),due to leaching.This geomorphological effect of soil fertility is most pronounced in the topsoil and decreases when considering the subsoil down to 50 cm depth.Few soil fertility attributes affect tree height after 1-2 years of growth,among which C stocks proved to be most important while pH_(KCl)and CEC only played minor roles.Nevertheless,soil acidity and a high proportion of Al on the exchange complex affected tree height even after only 1-2 years growth.Hence,our study showed that forest nutrition is coupled to a recycling of litter nutrients,and does not only depend on subsequent supply of nutrients from the mineral soil.Besides soil fertility,topography affected tree height.We found that especially MCCA as indicator of water availability affected tree growth at small-scale,as well as aspect.Overall,our synthesis on the interrelation between fertility,topography and tree growth in a subtropical forest ecosystem in SE China showed that topographic heterogeneity lead to ecological gradients across geomorphological positions.In this respect,small-scale soil-plant interactions in a young forest can serve as a driver for the future development of vegetation and biodiversity control on soil fertility.In addition,it shows that terrain attributes should be accounted for in ecological research. | Thomas Scholten Philipp Goebes Peter Kühn Steffen Seitz Thorsten Assmann Jürgen Bauhus Helge Bruelheide Francois Buscot Alexandra Erfmeier Markus Fischer Werner Härdtle Jin-Sheng He Keping Ma Pascal A.Niklaus Michael Scherer-Lorenzen Bernhard Schmid Xuezheng Shi Zhengshan Song Goddert von Oheimb Christian Wirth Tesfaye Wubet Karsten Schmidt | 2017 | Journal of Plant Ecology2017,10,1: | 22 |
| 4 | Single-cell transcriptomics reveals regulators underlying immune cell diversity and immune subtypes associated with prognosis in nasopharyngeal carcinoma显示文摘Nasopharyngeal carcinoma(NPC)is an aggressive malignancy with extremely skewed ethnic and geographic distributions.Increasing evidence indicates that targeting the tumor microenvironment(TME)represents a promising therapeutic approach in NPC,highlighting an urgent need to deepen the understanding of the complex NPC TME.Here,we generated single-cell transcriptome profiles for 7581 malignant cells and 40,285 immune cells from fifteen primary NPC tumors and one normal sample.We revealed malignant signatures capturing intratumoral transcriptional heterogeneity and predicting aggressiveness of malignant cells.Diverse immune cell subtypes were identified,including novel subtypes such as CLEC9A^+dendritic cells(DCs).We further revealed transcriptional regulators underlying immune cell diversity,and cell–cell interaction analyses highlighted promising immunotherapeutic targets in NPC.Moreover,we established the immune subtype-specific signatures,and demonstrated that the signatures of macrophages,plasmacytoid dendritic cells(pDCs),CLEC9A^+DCs,natural killer(NK)cells,and plasma cells were significantly associated with improved survival outcomes in NPC.Taken together,our findings represent a unique resource providing in-depth insights into the cellular heterogeneity of NPC TME and highlight potential biomarkers for anticancer treatment and risk stratification,laying a new foundation for precision therapies in NPC. | Yu-Pei Chen Jian-Hua Yin Wen-Fei Li Han-Jie Li Dong-Ping Chen Cui-Juan Zhang Jia-Wei Lv Ya-Qin Wang Xiao-Min Li Jun-Yan Li Pan-Pan Zhang Ying-Qin Li Qing-Mei He Xiao-Jing Yang Yuan Lei Ling-Long Tang Guan-Qun Zhou Yan-Ping Mao Chen Wei Ke-Xu Xiong Hong-Bo Zhang Shi-Da Zhu Yong Hou Ying Sun Michael Dean Ido Amit Kui Wu Dong-Ming Kuang Gui-Bo Li Na Liu Jun Ma | 2020 | Cell Research2020,30,11: | 19 |
| 5 | The Deep-Time Digital Earth program:data-driven discovery in geosciences显示文摘Current barriers hindering data-driven discoveries in deep-time Earth(DE)include:substantial volumes of DE data are not digitized;many DE databases do not adhere to FAIR(findable,accessible,interoperable and reusable)principles;we lack a systematic knowledge graph for DE;existing DE databases are geographically heterogeneous;a significant fraction of DE data is not in open-access formats;tailored tools are needed.These challenges motivate the Deep-Time Digital Earth(DDE)program initiated by the International Union of Geological Sciences and developed in cooperation with national geological surveys,professional associations,academic institutions and scientists around the world.DDE’s mission is to build on previous research to develop a systematic DE knowledge graph,a FAIR data infrastructure that links existing databases and makes dark data visible,and tailored tools for DE data,which are universally accessible.DDE aims to harmonize DE data,share global geoscience knowledge and facilitate data-driven discovery in the understanding of Earth’s evolution. | Chengshan Wang Robert MHazen Qiuming Cheng Michael HStephenson Chenghu Zhou Peter Fox Shu-zhong Shen Roland Oberhansli Zengqian Hou Xiaogang Ma Zhiqiang Feng Junxuan Fan Chao Ma Xiumian Hu Bin Luo Juanle Wang Craig M.Schiffries | 2021 | National Science Review2021,8,9: | 14 |
| 6 | Boceprevir,GC-376,and calpain inhibitors Ⅱ,Ⅻ inhibit SARS-CoV-2 viral replication by targeting the viral main protease显示文摘A new coronavirus SARS-CoV-2,also called novel coronavirus 2019(2019-nCoV),started to circulate among humans around December 2019,and it is now widespread as a global pandemic.The disease caused by SARS-CoV-2 virus is called COVID-19,which is highly contagious and has an overall mortality rate of 6.35%as of May 26,2020.There is no vaccine or antiviral available for SARS-CoV-2.In this study,we report our discovery of inhibitors targeting the SARS-CoV-2 main protease(Mpro).Using the FRET-based enzymatic assay,several inhibitors including boceprevir,GC-376,and calpain inhibitorsⅡ,andⅫwere identified to have potent activity with single-digit to submicromolar ICs0 values in the enzymatic assay.The mechanism of action of the hits was further characterized using enzyme kinetic studies,thermal shift binding assays,and native mass spectrometry.Significantly,four compounds(boceprevir,GC-376,calpain inhibitorsⅡandⅫ)inhibit SARS-CoV-2 viral replication in cell culture with EC50 values ranging from 0.49 to 3.37μM.Notably,boceprevir,calpain inhibitorsⅡandⅫrepresent novel chemotypes that are distinct from known substrate-based peptidomimetic Mpro inhibitors.A complex crystal structure of SARS-CoV-2 Mpro with GC-376,determined at 2.15(A)resolution with three protomers per asymmetric unit,revealed two unique binding configurations,shedding light on the molecular interactions and protein conformational flexibility underlying substrate and inhibitor binding by Mpro.Overall,the compounds identified herein provide promising starting points for the further development of SARS-CoV-2 therapeutics. | Chunlong Ma Michael Dominic Sacco Brett Hurst Julia Alma Townsend Yanmei Hu Tommy Szeto Xiujun Zhang Bart Tarbet Michael Thomas Marty Yu Chen Jun Wang | 2020 | Cell Research2020,30,8: | 13 |
| 7 | Soil respiration is driven by fine root biomass along a forest chronosequence in subtropical China显示文摘Aims Soil respiration(Rs)is a major process controlling soil carbon loss in forest ecosystems.However,the underlying mechanisms leading to variation in Rs along forest successional gradients are not well understood.In this study,we investigated the effects of biotic and abiotic factors on Rs along a forest successional gradient in southeast China.Methods We selected 16 plots stratified by forest age,ranging from 20 to 120 years.In each plot,six shallow collars and six deep collars were permanently inserted into the soil.Shallow and deep collars were used to measure Rs and heterotrophic respiration(Rh),respectively.Autotrophic soil respiration(Ra)was estimated as the difference between Rs and Rh.Litter layer respiration(R_(L))was calculated by subtracting soil respiration measured in collars without leaf litter layer(R_(NL))from Rs.Rs was measured every 2 months,and soil temperature(ST)and soil volumetric water content(SVWC)were recorded every hour for 19 months.We calculated daily Rs using an exponential model dependent on ST.Daily Rs was summed to obtain cumulative annual Rs estimates.Structural equation modelling(SEM)was applied to identify the drivers of Rs during forest succession.Important Findings Rs showed significant differences among three successive stages,and it was the highest in the young stage.Ra was higher in the young stage than in the medium stage.Cumulative annual Rs and Ra peaked in the young and old stages,respectively.Cumulative annual Rh and respiration measured from soil organic matter(R_(SOM))decreased,whereas R_(L)increased with forest age.The SEM revealed that cumulative annual Rs was influenced by fine root biomass and SVWC.Our results indicated that the dominant force regulating Rs on a seasonal scale is ST;however,on a successional scale,belowground carbon emerges as the dominant influential factor. | Chao Wang Yinlei Ma Stefan Trogisch Yuanyuan Huang Yan Geng Michael Scherer-Lorenzen Jin-Sheng He | 2017 | Journal of Plant Ecology2017,10,1: | 13 |
| 8 | Overexpression of an ABA biosynthesis gene using a stress-inducible promoter enhances drought resistance in petunia显示文摘The response of plants to drought stress includes reduced transpiration as stomates close in response to increased abscisic acid(ABA)concentrations.Constitutive overexpression of 9-cis-epoxycarotenoid dioxygenase(NCED),a key enzyme in ABA biosynthesis,increases drought resistance,but causes negative pleiotropic effects on plant growth and development.We overexpressed the tomato NCED(LeNCED1)in petunia plants under the control of a stress-inducible promoter,rd29A.Under water stress,the transgenic plants had increased transcripts of NCED mRNA,elevated leaf ABA concentrations,increased concentrations of proline,and a significant increase in drought resistance.The transgenic plants also displayed the expected decreases in stomatal conductance,transpiration,and photosynthesis.After 14 days without water,the control plants were dead,but the transgenic plants,though wilted,recovered fully when re-watered.Well-watered transgenic plants grew like non-transformed control plants and there was no effect of the transgene on seed dormancy. | Alejandro C Estrada-Melo Chao Ma Michael S Reid Cai-Zhong Jiang | 2015 | Horticulture Research2015,2,1: | 12 |
| 9 | A new prognostic histopathologic classification of nasopharyngeal carcinoma显示文摘Background:The current World Health Organization(WHO) classification of nasopharyngeal carcinoma(NPC) con?veys little prognostic information.This study aimed to propose an NPC histopathologic classification that can poten?tially be used to predict prognosis and treatment response.Methods:We initially developed a histopathologic classification based on the morphologic traits and cell differentia?tion of tumors of 2716 NPC patients who were identified at Sun Yat?sen University Cancer Center(SYSUCC)(training cohort).Then,the proposed classification was applied to 1702 patients(retrospective validation cohort) from hospitals outside SYSUCC and 1613 patients(prospective validation cohort) from SYSUCC.The efficacy of radiochemotherapy and radiotherapy modalities was compared between the proposed subtypes.We used Cox proportional hazards models to estimate hazard ratios(HRs) with 95% confidence intervals(CI) for overall survival(OS).Results:The 5?year OS rates for all NPC patients who were diagnosed with epithelial carcinoma(EC;3708 patients),mixed sarcomatoid?epithelial carcinoma(MSEC;1247 patients),sarcomatoid carcinoma(SC;823 patients),and squamous cell carcinoma(SCC;253 patients) were 79.4%,70.5%,59.6%,and 42.6%,respectively(P < 0.001).In mul?tivariate models,patients with MSEC had a shorter OS than patients with EC(HR = 1.44,95% CI = 1.27–1.62),SC(HR = 2.00,95% CI = 1.76–2.28),or SCC(HR = 4.23,95% CI = 3.34–5.38).Radiochemotherapy significantly improved survival compared with radiotherapy alone for patients with EC(HR 49–0.75),and possibly for those with SCC(HR = 0.67,95% CI = 0.56–0.80),MSEC(HR = 0.58,95% CI = 0..74–1.28).= 0.63;95% CI = 0.40–0.98),but not for patients with SC(HR = 0.97,95% CI = 0Conclusions:The proposed classification offers more information for the prediction of NPC prognosis compared with the WHO classification and might be a valuable tool to guide treatment decisions for subtypes that are associ?ated with a poor prognosis. | Hai-Yun Wang Yih-Leong Chang Ka-Fai To Jacqueline S.G.Hwang Hai-Qiang Mai Yan-Fen Feng Ellen T.Chang Chen-Ping Wang Michael Koon Ming Kam Shie-Lee Cheah Ming Lee Li Gao Hui-Zhong Zhang Jie-Hua He Hao Jiang Pei-Qing Ma Xiao-Dong Zhu Liang Zeng Chun-Yan Chen Gang Chen Ma-Yan Huang Sha Fu Qiong Shao An-Jia Han Hai-Gang Li Chun-Kui Shao Pei-Yu Huang Chao-Nan Qian Tai-Xiang Lu Jin-Tian Li Weimin Ye Ingemar Ernberg Ho Keung Ng Joseph T.S.Wee Yi-Xin Zeng Hans-Olov Adami Anthony T.C.Chan Jian-Yong Shao | 2016 | Chinese Journal of Cancer2016,35,6: | 10 |

| 12 | Low-dose real-time X-ray imaging with nontoxic double perovskite scintillators显示文摘X-rays are widely used in probing inside information nondestructively,enabling broad applications in the medical radiography and electronic industries.X-ray imaging based on emerging lead halide perovskite scintillators has received extensive attention recently.However,the strong self-absorption,relatively low light yield and lead toxicity of these perovskites restrict their practical applications.Here,we report a series of nontoxic double-perovskite scintillators of Cs_(2)Ag_(0.6)Na_(0.4)In_(1-y)Bi_(y)Cl_(6).By controlling the content of the heavy atom Bi^(3+),the X-ray absorption coefficient,radiative emission efficiency,light yield and light decay were manipulated to maximise the scintillator performance.A light yield of up to 39,000±7000 photons/MeV for Cs_(2)Ag_(0.6)Na_(0.4)In_(0.85)Bi_(0.15)Cl_(6) was obtained,which is much higher than that for the previously reported lead halide perovskite colloidal CsPbBr_(3)(21,000 photons/MeV).The large Stokes shift between the radioluminescence(RL)and absorption spectra benefiting from self-trapped excitons(STEs)led to a negligible selfabsorption effect.Given the high light output and fast light decay of this scintillator,static X-ray imaging was attained under an extremely low dose of ∼1μGy_(air),and dynamic X-ray imaging of finger bending without a ghosting effect was demonstrated under a low-dose rate of 47.2μGy_(air) s^(−1).After thermal treatment at 85℃ for 50 h followed by X-ray irradiation for 50 h in ambient air,the scintillator performance in terms of the RL intensity and X-ray image quality remained almost unchanged.Our results shed light on exploring highly competitive scintillators beyond the scope of lead halide perovskites,not only for avoiding toxicity but also for better performance. | Wenjuan Zhu Wenbo Ma Yirong Su Zeng Chen Xinya Chen Yaoguang Ma Lizhong Bai Wenge Xiao Tianyu Liu Haiming Zhu Xiaofeng Liu Huafeng Liu Xu Liu Yang(Michael)Yang | 2020 | Light(Science & Applications)2020,9,1: | 9 |
| 13 | Optical observations of LIGO source GW 170817 by the Antarctic Survey Telescopes at Dome A,Antarctica显示文摘The LIGO detection of gravitational waves(GW) from merging black holes in 2015 marked the beginning of a new era in observational astronomy. The detection of an electromagnetic signal from a GW source is the critical next step to explore in detail the physics involved. The Antarctic Survey Telescopes(AST3),located at Dome A, Antarctica, is uniquely situated for rapid response time-domain astronomy with its continuous night-time coverage during the austral winter. We report optical observations of the GW source(GW 170817) in the nearby galaxy NGC 4993 using AST3. The data show a rapidly fading transient at around 1 day after the GW trigger, with the i-band magnitude declining from 17:23 ± 0:13 magnitude to 17:72 ± 0:09 magnitude in ~1:8 h. The brightness and time evolution of the optical transient associated with GW 170817 are broadly consistent with the predictions of models involving merging binary neutron stars. We infer from our data that the merging process ejected about ~10^(-2) solar mass of radioactive material at a speed of up to 30% the speed of light. | lei hu xuefeng wu igor andreoni michael c.b.ashley jeff cooke xiangqun cui fujia du zigao dai bozhong gu yi hu haiping lu xiaoyan li zhengyang li ensi liang liangduan liu bin ma zhaohui shang tianrui sun n.b.suntzeff charling tao syed a.uddin lifan wang xiaofeng wang haikun wen di xiao jin xu ji yang shihai yang xiangyan yuan hongyan zhou hui zhang jilin zhou zonghong zhu | 2017 | Science Bulletin2017,62,21: | 6 |
| 14 | Differential gene expression in nontransgenic and transgenic“M.26”apple overexpressing a peach CBF gene during the transition from eco-dormancy to bud break显示文摘The CBF signal pathway is responsible for a significant portion of plant responses to low temperature and freezing.Overexpression of CBF genes in model organisms such as Arabidopsis thaliana enhances abiotic stress tolerance but also reduces growth.In addition to these effects,overexpression of the peach(Prunus persica[L.]Batsch)CBF1 gene in transgenic apple(Malus x domestica Borkh.)line T166 also results in early entry into and late exit from dormancy.Although the regulation of dormancy-induction and dormancy-release occur while the CBF regulon is operative in perennial,woody plants,how overexpression of CBF1 affects these dormancy-related changes in gene expression is incompletely understood.The objective of the present study was to characterize global changes in gene expression in peach CBF1-overexpressing and non-transformed apple bark tissues at different states of dormancy via RNA-seq.RNAseq bioinformatics data was confirmed by RT-qPCR on a number of genes.Results indicate that the greatest number of significantly differentially expressed genes(DEGs)occurred in April when dormancy release and bud break normally occur but are delayed in Line T166.Genes involved in storage and inactivation of auxin,GA,and cytokinin were generally upregulated in T166 in April,while those for biosynthesis,uptake or signal transduction were generally downregulated in T166.Genes for cell division and cambial growth were also downregulated in T166 relative to the non-transformed line.These data suggest that overexpression of the peach CBF1 gene impacts growth hormone homeostasis and as a result the activation of growth in the spring,and most likely growth cessation in the fall as well. | Timothy Artlip Adam McDermaid Qin Ma Michael Wisniewski | 2019 | Horticulture Research2019,6,1: | 6 |
| 15 | Perovskite semiconductors for direct X-ray detection and imaging显示文摘Halide perovskites have emerged as the next generation of optoelectronic materials and their remarkable performances have been attractive in the fields of solar cells,light-emitting diodes,photodetectors,etc.In addition,halide perovskites have been reported as an attractive new class of X-ray direct detecting materials recently,owning to the strong X-ray stopping capacity,excellent carrier transport,high sensitivity,and cost-effective manufacturing.Meanwhile,perovskite based direct Xray imagers have been successfully demonstrated as well.In this review article,we firstly introduced some fundamental principles of direct X-ray detection and imaging,and summarized the advances of perovskite materials for these purposes and finally put forward some needful and feasible directions. | Yirong Su Wenbo Ma Yang(Michael)Yang | 2020 | Journal of Semiconductors2020,41,5: | 6 |
| 16 | Temperature and velocity dependent friction of a microscale graphite-DLC heterostructure显示文摘One of the promising approaches to achieving large scale superlubricity is the use of junctions between existing ultra-flat surface together with superlubric graphite mesas.Here we studied the frictional properties of microscale graphite mesa sliding on the diamond-like carbon,a commercially available material with a ultra-flat surface.The interface is composed of a single crystalline graphene and a diamond-like carbon surface with roughness less than I nm.Using an integrated approach,which includes Argon plasma irradiation of diamond-like carbon surfaces,X-ray photoelectron spectroscopy analysis and Langmuir adsorption modeling,we found that while the velocity dependence of friction follows a thermally activated sliding mechanism,its temperature dependence is due to the desorption of chemical groups upon heating.These observations indicate that the edges have a significant contribution to the friction.Our results highlight potential factors affecting this type of emerging friction junctions and provide a novel approach for tuning their friction properties through ion irradiation. | Yujie GONGYANG Wengen OUYANG Cangyu QU Michael URBAKH Baogang QUAN Ming MA Quanshui ZHENG | 2020 | Friction2020,8,2: | 5 |
