3A novel m6A reader Prrc2a controls oligodendroglial specification and myelination显示文摘While N6-methyladenosine (m6A), the most abundant internal modification in eukaryotic mRNA, is linked to cell differentiation and tissue development, the biological significance of m6A modification in mammalian glial development remains unknown. Here, we identify a novel m6A reader, Prrc2a (Proline rich coiled-coil 2A), which controls oligodendrocyte specification and myelination. Nestin-Cre-mediated knockout of Prrc2a induces significant hypomyelination, decreased lifespan, as well as locomotive and cognitive defects in a mouse model. Further analyses reveal that Prrc2a is involved in oligodendrocyte progenitor cells (OPCs) proliferation and oligodendrocyte fate determination. Accordingly, oligodendroglial-lineage specific deletion of Prrc2a causes a similar phenotype of Nestin-Cre-mediated deletion. Combining transcriptome-wide RNA-seq, m6A-RIP-seq and Prrc2a RIP-seq analysis, we find that Olig2 is a critical downstream target gene of Prrc2a in oligodendrocyte development. Furthermore, Prrc2a stabilizes Olig2 mRNA through binding to a consensus GGACU motif in the Olig2 CDS (coding sequence) in an m6A-dependent manner. Interestingly, we also find that the m6A demethylase, Fto, erases the m6A modification of Olig2 mRNA and promotes its degradation. Together, our results indicate that Prrc2a plays an important role in oligodendrocyte specification through functioning as a novel m6A reader. These findings suggest a new avenue for the development of therapeutic strategies for hypomyelination-related neurological diseases.Rong Wu Ang Li Baofa Sun Jian-Guang Sun Jinhua Zhang Ting Zhang Yusheng Chen Yujie Xiao Yuhao Gao Qingyang Zhang Jun Ma Xin Yang Yajin Liao Wei-Yi Lai Xiaolong Qi Shukun Wang Yousheng Shu Hai-Lin Wang Fengchao Wang Yun-Gui Yang Zengqiang Yuan 2019Cell Research2019,29,1:32

5A method to estimate concentrations of surface-level particulate matter using satellite-based aerosol optical thickness显示文摘We propose a new method to estimate surface-level particulate matter(PM)concentrations by using satellite-retrieved Aerosol Optical Thickness(AOT).This method considers the distribution and variation of Planetary Boundary Layer(PBL)height and relative humidity(RH)at the regional scale.The method estimates surface-level particulate matter concentrations using the data simulated by an atmospheric boundary layer model RAMS and satellite-retrieved AOT.By incorporation MODIS AOT,PBL height and RH simulated by RAMS,this method is applied to estimate the surface-level PM 2.5 concentrations in North China region.The result is evaluated by using 16 ground-based observations deployed in the research region,and the result shows a good agreement between estimated PM 2.5 concentrations and observations,and the coefficient of determination R2 is 0.61 between the estimated PM 2.5 concentrations and the observations.In addition,surface-level PM 2.5 concentrations are also estimated by using MODIS AOT,ground-based LIDAR observations and RH measurements.A comparison between the two estimated PM 2.5 concentrations shows that the new method proposed in this paper is better than the traditional method.The coefficient of determination R2 is improved from 0.32 to 0.62.TAO JinHua ZHANG MeiGen CHEN LiangFu WANG ZiFeng SU Lin GE Cui HAN Xiao ZOU MingMin 2013Science China Earth Sciences2013,56,8:20
6Inhibition of FOXO3a/BIM signaling pathway contributes to the protective effect of salvianolic acid A against cerebral ischemia/reperfusion injury显示文摘Salvianolic acid A(SalA) is an effective compound extracted from traditional Chinese medicine Salvia miltiorrhiza Bunge. The Forkhead box O3a(FOXO3a) signaling pathway plays crucial roles in the modulation of ischemia-induced cell apoptosis. However, no information about the regulatory effect of SalA on FoxO3a is available. To explore the anti-cerebral ischemia effect and clarify the therapeutic mechanism of SalA, SH-SY5Y cells and Sprague–Dawley rats were applied, which were exposed to oxygen glucose deprivation/reoxygenation(OGD/R) and middle cerebral artery occlusion/reperfusion(MCAO/R) injuries, respectively. The involved pathway was identified using the specific inhibitor LY294002. Results showed that SalA concentration-dependently inhibited OGD/R injury triggered cell viability loss. SalA reduced cerebral infarction, lowered brain edema, improved neurological function, and inhibited neuron apoptosis in MCAO/R rats, which were attenuated by the treatment of phosphatidylinositol-4,5-bisphosphate 3-kinase(PI3K) specific inhibitor LY294002. SalA time-and concentration-dependently upregulated the phosphorylation levels of protein kinase B(AKT) and its downstream protein FOXO3a. Moreover, the nuclear translocation of FOXO3a was inhibited by SalA both in vivo and in vitro, which was also reversed by LY294002. The above results indicated that SalA fought against ischemia/reperfusion damage at least partially via the AKT/FOXO3a/BIM pathway.Junke Song Wen Zhang Jinhua Wang Haiguang Yang Qimeng Zhou Haigang Wang Li Li Guanhua Du 2019Acta Pharmaceutica Sinica B2019,9,3:20
7Modeling study of residence time and water age in Dahuofang Reservoir in China显示文摘Understanding the dynamics of water renewal in a reservoir is essential when the transport and fate of dissolved substances are evaluated.A three-dimensional hydrodynamic model was implemented to compute average residence time and water age in Dahuofang Reservoir in China.The model was verified for a one-year time period in 2006.A simulation reproduced intra-annual variation of mixing represented by the fall/winter mixing and the spring/summer stratification.The simulated variation of vertical thermal structures also matched observation.The spatially varying average residence times and age distribution were investigated through a series of numerical experiments using a passively dissolved and conservative tracer as a surrogate.Residence time estimations yield a broad range of values depending on the position.The average residence time for a tracer placed at the head of the reservoir under high-,mean-,and low flow conditions was found to be about 125,236 and 521 days,respectively.The age simulation reveals that the age distribution is a function of the freshwater discharge.In the vertical direction,the age of the surface layers is larger than that of the bottom layers and the age difference between the surface and bottom layers decreases further downstream.The density-induced circulation plays an important role in the circulation in the reservoir,and can generate vertical age distribution in the reservoir.These findings provide useful information for understanding the transport process in Dahuofang Reservoir that can be used to assist the water quality management of the reservoir.SHEN YongMing WANG JinHua ZHENG BingHui ZHEN Hong FENG Yu WANG ZaiXing YANG Xu 2011Science China(Physics,Mechanics & Astronomy)2011,54,1:18

9Wnt and BMP signaling crosstalk in regulating dental stem cells:Implications in dental tissue engineering显示文摘Tooth is a complex hard tissue organ and consists of multiple cell types that are regulated by important signaling pathways such as Wnt and BMP signaling.Serious injuries and/or loss of tooth or periodontal tissues may significantly impact aesthetic appearance,essential oral functions and the quality of life.Regenerative dentistry holds great promise in treating oral/dental disorders.The past decade has witnessed a rapid expansion of our understanding of the biological features of dental stem cells,along with the signaling mechanisms governing stem cell self-renewal and differentiation.In this review,we first summarize the biological characteristics of seven types of dental stem cells,including dental pulp stem cells,stem cells from apical papilla,stem cells from human exfoliated deciduous teeth,dental follicle precursor cells,periodontal ligament stem cells,alveolar bone-derived mesenchymal stem cells(MSCs),and MSCs from gingiva.We then focus on how these stem cells are regulated by bone morphogenetic protein(BMP)and/or Wnt signaling by examining the interplays between these pathways.Lastly,we analyze the current status of dental tissue engineering strategies that utilize oral/dental stem cells by harnessing the interplays between BMP and Wnt pathways.We also highlight the challenges that must be addressed before the dental stem cells may reach any clinical applications.Thus,we can expect to witness significant progresses to be made in regenerative dentistry in the coming decade.Fugui Zhang Jinlin Song Hongmei Zhang Enyi Huang Dongzhe Song Viktor Tollemar Jing Wang Jinhua Wang Maryam Mohammed Qiang Wei Jiaming Fan Junyi Liao Yulong Zou Feng Liu Xue Hu Xiangyang Qu Liqun Chen Xinyi Yu Hue H.Luu Michael J.Lee Tong-Chuan He Ping Ji 2016Genes & Diseases2016,3,4:16
10Development and validation of a three-dimensional,wave-current coupled model on unstructured meshes显示文摘Using unstructured meshes provides great flexibility for modeling the flow in complex geomorphology of tidal creeks,barriers and islands,with refined grid resolution in regions of interest and not elsewhere.In this paper,an unstructured three-dimensional fully coupled wave-current model is developed.Firstly,a parallel,unstructured wave module is developed.Variations in wave properties are governed by a wave energy equation that includes wave-current interactions and dissipation representative of wave breaking.Then,the existing Finite-Volume Coastal Ocean Model(FVCOM) is modified to couple with the wave module.The couple procedure includes depth dependent wave radiation stress terms,Stokes drift,vertical transfer of wave-generated pressure transfer to the mean momentum equation,wave dissipation as a source term in the turbulence kinetic energy equation,and mean current advection and refraction of wave energy.Several applications are presented to evaluate the developed model.In particular the wind and wave-induced storm surge generated by Hurricane Katrina is investigated.The obtained results have been compared to the in situ measurements with respect to the wave heights and water level elevations revealing good accuracy of the model in reproduction of the investigated events.In a comparison to water level measurements at Dauphin Island,inclusion of the wave induced water level setup reduced the normalized root mean square error from 0.301 to 0.257 m and increased the correlation coefficient from 0.860 to 0.929.Several runs were carried out to analyze the effects of waves.The experiments show that among the processes that represent wave effects,radiation stress and wave-induced surface stress are more important than wave-induced bottom stress in affecting the water level.The Hurricane Katrina simulations showed the importance of the inclusion of the wave effects for the hindcast of the water levels during the storm surge.WANG JinHua SHEN YongMing 2011Science China(Physics,Mechanics & Astronomy)2011,54,1:16
11Sinomenine ester derivative inhibits glioblastoma by inducing mitochondria-dependent apoptosis and autophagy by PI3K/AKT/mTOR and AMPK/mTOR pathway显示文摘Glioblastoma multiforme(GBM)in the central nervous system is the most lethal advanced glioma and currently there is no effective treatment for it.Studies of sinomenine,an alkaloid from the Chinese medicinal plant,Sinomenium acutum,showed that it had inhibitory effects on several kinds of cancer.Here,we synthesized a sinomenine derivative,sino-wcj-33(SW33),tested it for antitumor activity on GBM and explored the underlying mechanism.SW33 significantly inhibited proliferation and colony formation of GBM and reduced migration and invasion of U87 and U251 cells.It also arrested the cell cycle at G2/M phase and induced mitochondria-dependent apoptosis.Differential gene enrichment analysis and pathway validation showed that SW33 exerted anti-GBM effects by regulating PI3 K/AKT and AMPK signaling pathways and significantly suppressed tumorigenicity with no obvious adverse effects on the body.SW33 also induced autophagy through the PI3 K/AKT/mTOR and AMPK/mTOR pathways.Thus,SW33 appears to be a promising drug for treating GBM effectively and safely.Xiangjin Zheng Wan Li Huanli Xu Jinyi Liu Liwen Ren Yihui Yang Sha Li Jinhua Wang Tengfei Ji Guanhua Du 2021Acta Pharmaceutica Sinica B2021,11,11:15
12MicroRNAs in tomato plants显示文摘MicroRNAs (miRNAs) are a specialized class of small silencing RNAs that regulate gene expression in eukaryotes.In plants,miRNAs negatively regulate target mRNAs containing a highly complementary sequence by either mRNA cleavage or translational repression.As a model plant to study fleshy fruit ripening,miRNA studies in tomato have made great progress recently.MiRNAs were predicted to be involved in nearly all biological processes in tomato,particularly development,differentiation,and biotic and abiotic stress responses.Surprisingly,several miRNAs were verified to be involved in tomato fruit ripening and senescence.Recent studies suggest that miRNAs are related to host-virus interactions,which raises the possibility that miRNAs can be used as diagnostic markers for response to virus infection in tomato plants.In this review,we summarize our current knowledge systematically and advance future directions for miRNA research in tomato.ZUO JinHua WANG YunXiang LIU HaiPing MA YuanZheng JU Zheng ZHAI BaiQiang FU DaQi ZHU Yi LUO YunBo ZHU BenZhong 2011Science China(Life Sciences)2011,54,7:13
13Mild hypothermia combined with a scaffold of Ng Rsilenced neural stem cells/Schwann cells to treat spinal cord injury显示文摘Because the inhibition of Nogo proteins can promote neurite growth and nerve cell differentiation, a cell-scaffold complex seeded with Nogo receptor(Ng R)-silenced neural stem cells and Schwann cells may be able to improve the microenvironment for spinal cord injury repair. Previous studies have found that mild hypothermia helps to attenuate secondary damage in the spinal cord and exerts a neuroprotective effect. Here, we constructed a cell-scaffold complex consisting of a poly(D,L-lactide-co-glycolic acid)(PLGA) scaffold seeded with Ng R-silenced neural stem cells and Schwann cells, and determined the effects of mild hypothermia combined with the cell-scaffold complexes on the spinal cord hemi-transection injury in the T9 segment in rats. Compared with the PLGA group and the Ng R-silencing cells + PLGA group, hindlimb motor function and nerve electrophysiological function were clearly improved, pathological changes in the injured spinal cord were attenuated, and the number of surviving cells and nerve fibers were increased in the group treated with the Ng R-silenced cell scaffold + mild hypothermia at 34°C for 6 hours. Furthermore, fewer pathological changes to the injured spinal cord and more surviving cells and nerve fibers were found after mild hypothermia therapy than in injuries not treated with mild hypothermia. These experimental results indicate that mild hypothermia combined with Ng R gene-silenced cells in a PLGA scaffold may be an effective therapy for treating spinal cord injury.Dong Wang Jinhua Liang Jianjun Zhang Shuhong Liu Wenwen Sun 2014Neural Regeneration Research2014,9,24:12
14Uterine Rbpj is required for embryonic-uterine orientation and decidual remodeling via Notch pathway-independent and -dependent mechanisms显示文摘协调的子宫胚胎的轴形成并且蜕膜的改变是哺乳动物的培植以后的胚胎开发的特点。胚胎子宫的取向在起始的培植被决定并且与蜕膜的开发同步。然而,控制这些事件的分子的机制留下尽管有它的发现逃犯很长时间以前。在现在的学习,我们发现了 Rbpj 的那子宫特定的删除,槽口发信号的原子变换器,在培植以后的阶段导致了反常胚胎子宫的取向和蜕膜的 patterning,导致实质的胚胎损失。我们进一步表明在胚胎附件以前, Rbpj 授与在时间上经由身体上与子宫的雌激素受体交往的子宫的腔形状转变(ERα) 以一种槽口小径无关的方式,它为在有子宫的轴的排列的胚胎取向的起始的建立是必要的。当时在培植以后的阶段, Rbpj 直接以一种槽口小径依赖者方式调整子宫的矩阵 metalloproteinase 的表示,它为正常被要求培植以后的蜕膜的改变。这些结果证明子宫的 Rbpj 为经由指示起始的胚胎子宫的取向并且以一种阶段特定的方式保证正常蜕膜的 patterning 的正常胚胎开发是必要的。我们的数据也证实正常哺乳动物的胚胎子宫的取向要求的概念合适的指导从发展地控制了子宫的发信号。Shuang Zhang Shuangbo Kong Bingyan Wang Xiaohong Cheng Yongjie Chen Weiwei Wu Qiang Wang Junchao Shi Ying Zhang Shumin Wang Jinhua Lu John P Lydon Francesco DeMayo Warren S Pear Hua Han Haiyan Lin Lei Li Hongmei Wang Yan-ling Wang Bing Li Qi Chen Enkui Duan Haibin Wang 2014Cell Research2014,24,8:12
15Retrieval of aerosol optical depth over bright targets in the urban areas of North China during winter显示文摘Two factors that affect satellite retrieval of Aerosol Optical Depth(AOD) are aerosol model assumptions and the separation of surface reflectance.NASA/MODIS Dense Dark Vegetation(DDV) algorithm has been proven valuable in deriving aerosol distribution and properties over land;however,it cannot be applied to bright targets.As a supplement to the DDV algorithm,an algorithm to retrieve AOD over urban areas in North China in winter is developed using MODIS data,including(1) the generation and analysis of adjacent clear-days surface reflectance using MOD09 product from 2007 to 2008,and(2) seasonal aerosol models derived from AERONET data in Beijing and Xianghe sites.Ground-based measurements using sun photometers were used to validate the retrieved AOD,and the correlation coefficient(r) is up to 0.931.Especially for high AOD values(AOD>0.4),more retrievals meet the inversion accuracy.The temporal variations of retrieval errors over urban,rural and mountain regions were examined,and the results indicated that the variation of blue-band surface reflectance is less than 0.02 in a short period except for unusual weather conditions,the retrieval bias is under 0.08,and the relative error decreases as the AOD increases.LI ShenShen CHEN LiangFu TAO JinHua HAN Dong WANG ZhongTing SU Lin FAN Meng YU Chao 2012Science China Earth Sciences2012,55,9:11
16Flame spread over the surface of thermal insulation materials in different environments显示文摘Experiments were conducted in a plateau area in Lhasa and a plain area in Hefei China to investigate the flame spread characteristics on thermal insulation materials under different environmental conditions (pressure and oxygen concentration).Molded polystyrene foam (EPS) and extruded polystyrene foam (XPS) samples were placed horizontally on a small-scale flame spread experimental bench.Changes in the average length of the pool fire,flame spread speed,average flame height,and length of preheating zone were used to determine the effect of the plateau and plain environments on flame spread characteristics.These parameters were all larger in Hefei than in Lhasa,which indicates the fire hazard in Hefei will be higher than that in Lhasa if insulation materials of the same size are used.HUANG XinJie SUN JinHua JI Jie ZHANG Ying WANG QingSong ZHANG Yi 2011Chinese Science Bulletin2011,56,15:10
17The efficiency and toxicity of dodecafluoro-2-methylpentan-3-one in suppressing lithium-ion battery fire显示文摘Currently,the effective and clean suppression of lithium-ion battery(LIB)fires remains a challenge.The present work investigates the use of various inhibitor doses(Xin)of dodecafluoro-2-methylpentan-3-one(C_(6) F_(12)O)in 300 Ah LIBs,and systematically examines the thermal and toxic hazards of the extinguished batteries via real scale combustion and gas analysis.The inhibitor is shown to be completely effective.The inhibition mechanism involves a combination of chemical inhibition and physical cooling.While the chemical inhibition effect tends to saturate with increasing Xin,the physical cooling remains effective at higher inhibitor doses.However,extinguishing the battery fire with a high Xin of C_(6)F_(12)O is found to incur serious toxicity problems.These results are expected to provide a guideline for the design of inhibitor doses for the suppression of LIB fires.Yujun Liu Kai Yang Mingjie Zhang Shi Li Fei Gao Qiangling Duan Jinhua Sun Qingsong Wang 2022Journal of Energy Chemistry2022,31,2:10
18Curcumin protects against ischemic spinal cord injury The pathway effect显示文摘Inducible nitric oxide synthase and N-methyl-D-aspartate receptors have been shown to participate in nerve cell injury during spinal cord ischemia.This study observed a protective effect of curcumin on ischemic spinal cord injury.Models of spinal cord ischemia were established by ligating the lumbar artery from the left renal artery to the bifurcation of the abdominal aorta.At 24 hours after model establishment,the rats were intraperitoneally injected with curcumin.Reverse transcription-polymerase chain reaction and immunohistochemical results demonstrated that after spinal cord ischemia,inducible nitric oxide synthase and N-methyl-D-aspartate receptor mRNA and protein expression significantly increased.However,curcumin significantly decreased inducible nitric oxide synthase and N-methyl-D-aspartate receptor mRNA and protein expression in the ischemic spinal cord.Tarlov scale results showed that curcumin significantly improved motor function of the rat hind limb after spinal cord ischemia.The results demonstrate that curcumin exerts a neuroprotective effect against ischemic spinal cord injury by decreasing inducible nitric oxide synthase and N-methyl-D-aspartate receptor expression.Jinhua Zhang Hao Wei Meimei Lin Chunmei Chen Chunhua Wang Maobai Liu 2013Neural Regeneration Research2013,8,36:9
19Zircon SHRIMP U-Pb age and geological implications of tuff at the bottom of Chang-7 Member of Yanchang Formation in the Ordos Basin显示文摘A table tuff interlayer at the bottom of Chang-7 Member of Yanchang Formation,the Ordos Basin,may serve as an indicator for stratigraphic division and correlation.In this study,zircon SHRIMP U-Pb dating was performed on the tuff at the bottom of Chang-7 Member using samples from wells Luo-36 and Zhuang-211 in the southwest of the basin,which yielded weighted average 206Pb/238U ages of 241.3±2.4 and 239.7±1.7 Ma,respectively.The cathodoluminescence images and the U/Th element ratio of tuff indicate that the zircons are magmatogenic and their ages represent that of the sedimentation age of the tuff at the bottom of Chang-7,which is 239.7–241.3 Ma in age.This finding confirms presence of the Middle Triassic strata at the bottom of Yanchang Formation.Taking previous findings into account,we suggest restricing the Late Triassic Yanchang Formation sensu stricto to the interval from Chang-7 to Chang-1 and assigning the interval from Chang-10 to Chang-8 as the Tongchuan Formation.The tuff at the bottom of the Chang-7 Member of Yanchang Formation represents the sedimentary response to the Qinling orogenic event in the early Indosinian.This tectonic event resulted in major changes in paleogeomorphology and the sedimentary environment of the lake basin during deposition of the Yanchang Formation.During this period,extremely favourable conditions were present for subsequent hydrocarbon generation and pooling of lake basin.WANG DuoYun XIN BuShe YANG Hua FU JinHua YAO JinLi ZHANG Yu 2014Science China Earth Sciences2014,57,12:9
20Development of an integrated model system to simulate transport and fate of oil spills in seas显示文摘A three-dimensional integrated model is developed for simulating transport and final fate of oil spills in seas.The model contains two main modules,flow and transport-fate modules.The flow module uses an unstructured finite-volume wave-ocean coupling model.Using unstructured meshes provides great flexibility for modeling the flow in complex geometries of tidal creeks,barriers and islands.In the transport-fate module the oil dispersion is solved using a particle-tracking method.Horizontal diffusion is simulated using random walk techniques in a Monte Carlo framework,whereas the vertical diffusion process is solved on the basis of the Langeven equation.The model simulates the most significant processes that affect the motion of oil particles,such as advection,surface spreading,evaporation,dissolution,emulsification and turbulent diffusion as well as the interaction of the oil particles with the shoreline,sedimentation and the temporal variations of oil viscosity,density and surface tension.The model simulates either continuous or instantaneous oil spills,and also other toxic matter.This model has been applied to simulate the oil spill accident in the Bohai Sea.In comparison with the observations,the numerical results indicate that the model is reasonably accurate.WANG JinHua & SHEN YongMing State Key Laboratory of Coastal and Offshore Engineering,Dalian University of Technology,Dalian 116023,China 2010Science China(Technological Sciences)2010,53,9:9
