3A cyclic nucleotide-gated channel mediates cytoplasmic calcium elevation and disease resistance in rice显示文摘The transient elevation of cytoplasmic calcium is essential for pathogen-associated molecular pattern(PAMP)-triggered immunity(PTI).However,the calcium channels responsible for this process have remained unknown.Here,we show that rice CDSI(CELL DEATH and SUSCEPTIBLE to BLAST 1)encoding OsCNGC9;a cyclic nucleotide-gated channel protein,positively regulates the resistance to rice blast disease.We show that OsCNGC9 mediates PAMP-induced Ca2+influx and that this event is critical for PAMPs-triggered ROS burst and induction of PTI-related defense gene expression.We further show that a PTI related receptor-lih cytoplasmic kinase OsRLCK185 physically interacts with and phosphorylates OsCNGC9 to activate its channel activity.Our results suggest a signaling cascade linking pattern recognition to calcium channel activation,which is required for initiation of PTI and disease resistance in rice.Jiachang Wang Xi Liu An Zhang Yulong Ren Fuqing Wu Gang Wang Yang Xu Cailin Lei Shanshan Zhu Tian Pan Yongfei Wang Huan Zhang Fan Wang Yan-Qiu Tan Yupeng Wang Xin Jin Sheng Luo Chunlei Zhou Xiao Zhang Jinling Liu Shuai Wang Lingzhi Meng Yihua Wang Xi Chen Qibing Lin Xin Zhang Xiuping Guo Zhijun Cheng Jiulin Wang Yunlu Tian Shijia Liu Ling Jiang Chuanyin Wu Ertao Wang Jian-Min Zhou Yong-Fei Wang Haiyang Wang Jianmin Wan 2019Cell Research2019,29,10:13
4Factors Associated with Thrombolysis Outcome in Ischemic Stroke Patients with Atrial Fibrillation显示文摘The outcome of early intravenous thrombolysis for ischemic stroke in patients with atrial fibrillation(AF)is worse than that without thrombosis. How to increase the efficacy of intravenous thrombolysis for AF-related ischemic stroke remains largely unknown. In this study, we investigated factors that influence the effect of intravenous thrombolysis in these patients. Our results showed that thrombolysis was independently associated with a favorable outcome(P \ 0.001) and did not influence the mortality of AF-related ischemic stroke, although it increased the risk of hemorrhage within 24 h after treatment. Risk factors for a poor outcome at admission were:heart failure(P = 0.045); high systolic pressure(P = 0.039); high blood glucose(P = 0.030); and a high National Institutes of Health Stroke Scale(NIHSS) score(P \ 0.001). Moreover, high systolic pressure at admission(P = 0.007), high blood glucose(P = 0.027), and a high NIHSS score(P \ 0.001) were independent risk factors for mortality at 3 months. Besides thrombolysis, a high NIHSS score(P = 0.006) and warfarin taken within 48 h before stroke onset(P = 0.032) were also independent risk factors for symptomatic hemorrhage within 24 h after treatment. Ischemic stroke patients with AF benefited from intravenous thrombolysis with recombinant tissue plasminogen activator within 4.5 h after stroke.Qiuyun Zhao Xiaobo Li Wanli Dong Min Ye Yongjun Cao Meijuan Zhang Qiantao Cheng Junshan Zhou Guofang Chen Ming Yu Shanshan Hong Xiue Wei Bei Wang Guiyun Cui Peng Zhang Hong Ding Rongzhen Xu Yan Chen Yun Xu 2016Neuroscience Bulletin2016,32,2:13
5Detection and fine-mapping of SC7 resistance genes via linkage and association analysis in soybean显示文摘Soybean mosaic virus(SMV) disease is one of the most serious and broadly distributed soybean(Glycine max(L.) Merr.) diseases. Here, we combine the advantages of association and linkage analysis to identify and fine-map the soybean genes associated with resistance to SMV strain SC7.A set of 191 soybean accessions from different geographic origins and 184 recombinant inbred lines(RILs) derived from Kefeng No.1(resistant) Nannong 1138-2(susceptible) were used in this study. The SC7 resistance genes were previously mapped to a 2.65 Mb region on chromosome 2 and a 380 kb region on chromosome 13. Among 19 single nucleotide polymorphisms(SNPs) detected via association analysis in the study, the SNP BARC-021625-04157 was located in the2.65 Mb region, and the SNP BARC-041671-08065 was located near the 380 kb region; three genes harboring the SNPs were probably related to SC7 resistance. The resistance gene associated with BARC-021625-04157 was then finemapped to a region of approximately 158 kb on chromosome2 using 184 RILs. Among the 15 genes within this region, one NBS-LRR type gene, one HSP40 gene and one serine carboxypeptidase-type gene might be candidate SC7 resistance genes. These results will be useful for map-based cloning and marker-assisted selection in soybean breeding programs.Honglang Yan Hui Wang Hao Cheng Zhenbin Hu Shanshan Chu Guozheng Zhang Deyue Yu 2015Journal of Integrative Plant Biology2015,57,8:10
6Transcriptional activation and phosphorylation of OsCNGC9 confer enhanced chilling tolerance in rice显示文摘Low temperature is a major environmental factor that limits plant growth and productivity.Although transient elevation of cytoplasmic calcium has long been recognized as a critical signal for plant cold tolerance,the calcium channels responsible for this process have remained largely elusive.Here we report that OsCNGC9,a cyclic nucleotide-gated channel,positively regulates chilling tolerance by mediating cytoplasmic calcium elevation in rice(Oryza sativa).We showed that the loss-of-function mutant of OsCNGC9 is defective in cold-induced calcium influx and more sensitive to prolonged cold treatment,whereas OsCNGC9 overexpression confers enhanced cold tolerance.Mechanistically,we demonstrated that in response to chilling stress,OsSAPK8,a homolog of Arabidopsis thaliana OST1,phosphorylates and activates OsCNGC9 to trigger Ca2+influx.Moreover,we found that the transcription of OsCNGC9 is activated by a rice dehydration-responsive element-binding transcription factor,OsDREB1A.Taken together,our results suggest that OsCNGC9 enhances chilling tolerance in rice through regulating cold-induced calcium influx and cytoplasmic calcium elevation.Jiachang Wang Yulong Ren Xi Liu Sheng Luo Xiao Zhang Xin Liu Qibing Lin Shanshan Zhu Hua Wan Yang Yang Yu Zhang Bin Lei Chunlei Zhou Tian Pan Yongfei Wang Mingming Wu Ruonan jing Yang Xu Meng Han Fuqing Wu Cailin Lei Xiuping Guo Zhijun Cheng Xiaoming Zheng Yihua Wang Zhigang Zhao Ling Jiang Xin Zhang Yong-Fei Wang Haiyang Wang Jianmin Wan 2021Molecular Plant2021,14,2:10
7GW5-Like, a homolog of GW5, negatively regulates grain width, weight and salt resistance in rice显示文摘Grain size is an important determinant of yield potential in crops. We previously demonstrated that natural mutations in the regulatory sequences of qSW5/GW5 confer grain width diversity in rice. However, the biological function of a GW5 homolog, named GW5-Like(GW5 L), remains unknown. In this study, we report on GW5 L knockout mutants in Kitaake, a japonica cultivar(cv.)considered to have a weak gw5 variant allele that confers shorter and wider grains. GW5 L is evenly expressed in various tissues, and its protein product is localized to the plasma membrane. Biochemical assays verified that GW5 L functions in a similar fashion to GW5. It positively regulates brassinosteroid(BR) signaling through repression of the phosphorylation activity of GSK2. Genetic data show that GW5 L overexpression in either Kitaake or a GW5 knockout line, Kasaorf3(indica cv. Kasalath background), causes more slender, longer grains relative to the wild-type. We also show that GW5 L could confer salt stress resistance through an association with calmodulin protein OsCa M1-1. These findings identify GW5 L as a negative regulator of both grain size and salt stress tolerance, and provide a potential target for breeders to improve grain yield and salt stress resistance in rice.Peng Tian Jiafan Liu Changling Mou Cuilan Shi Huan Zhang Zhichao Zhao Qibing Lin Jie Wang Jiulin Wang Xin Zhang Xiuping Guo Zhijun Cheng Shanshan Zhu Yulong Ren Cailin Lei Haiyang Wang Jianmin Wan 2019Journal of Integrative Plant Biology2019,61,11:9

9Occurrence of mycotoxins in feed ingredients and complete feeds obtained from the Beijing region of China显示文摘Background:The current study was carried out to provide a reference for the control of mycotoxin contamination in feed ingredients and complete feeds for swine.Methods:A total of 55 feed ingredients,including 14 corn,13 wheat bran,11 soybean meal and 17 dried distillers grains with solubles(DDGS) as well as 76 complete swine feeds including 7 creep feeds,14 starter feeds,14 grower feeds,18 grower-finisher feeds,10 gestating sow feeds,and 13 lactating sow feeds were randomly collected from15 swine farms located in the Beijing region of China from July to August 2011.Immunoaffinity clean-up,using High-Performance Liquid Chromatography(HPLC) in combination with UV or Fluorescence Detection,was used for quantitative analysis of aflatoxin B,(AFB,),deoxynivalenol(DON),zearalenone(ZEA) and ochratoxin A(OTA) in the ingredients and complete feeds.Results:DON and ZEA were the most prevalent mycotoxins found.DON was detected at percentages of 93,92,54,100 and 97%with a mean level of 1.01,0.44,0.05,1.36 and 0.65 ppm in the samples of corn,wheat bran,soybean meal,DDGS and complete feeds,respectively.The detected percentages of ZEA were 100,100,54,100 and 100 with mean levels of 109.1,14.9,9.2,882.7 and 58.9 ppb in the same samples.In the wheat bran and soybean meal samples,the content of all four mycotoxins were below the maximum limits set by Chinese regulations while the percentage of samples that exceeded regulatory limits were 7,57 and 7%for corn,and 7,14 and 3%for the complete feeds for AFB,,DON and OTA respectively.DDGS showed the most serious mycotoxin contamination and the percentage of samples that exceeded regulatory limits were 6,88 and 41%,for AFB,,DON and ZEA,respectively.Conclusions:This paper is the first to present data on the natural occurrence of AFB,,DON,ZEA and OTA in ingredients and complete feeds obtained from swine farms in China's Beijing region.The data shows that feed ingredients and complete swine feeds obtained from these farms are most often contaminated with DON followed by contamination with AFB,and ZEA.Xiaoying Li Lihong Zhao Yu Fan Yaxiong Jia Lei Sun Shanshan Ma Cheng Ji Qiugang Ma Jianyun Zhang 2014Journal of Animal Science and Biotechnology2014,5,4:7
10Activation of various brain areas during acupuncture at Taixi (KI 3) and Qiuxu (GB 40) acupoints显示文摘A number of previous studies of acupuncture acupoint specificity have used sham acupoints,sham acupuncture or meridian acupoints at a great distance from each other as controls in functional MRI (fMRI) experiments.However,few studies have compared different meridian acupoints within the same segment,which are associated with similarly intense needle sensations.We performed fMRI on 12 healthy young volunteers and observed differences in brain activation elicited by acupuncture of the Taixi (KI 3) and Qiuxu (GB 40) acupoints.Acupuncture was applied at the Taixi and Qiuxu acupoints,using a multiple-block fMRI design with three blocks,involving three alternations of resting and task phases.After scanning,needle sensation was assessed.The behavioral results revealed that the subjective needle sensation was similar between the Taixi and Qiuxu acupoints.The fMRI results revealed that acupuncture at the right Taixi acupoint activated the right superior temporal gyrus (BA 22),left middle frontal gyrus (BA 46) and inferior frontal gyrus (BA 45),bilateral parietal lobe postcentral gyrus (BA 2),right parietal lobe (BA 3),and left parietal lobe (BA 40).Acupuncture at the right Qiuxu acupoint activated the left superior temporal gyrus (BA 42),right parietal lobe postcentral gyrus (BA 40,BA 43),right inferior frontal gyrus (BA 47),bilateral superior temporal gyrus (BA 22),and right insula BA13.These results suggest that the right Taixi and Qiuxu acupoints activated different brain areas.Shangjie Chen Huajun Cheng Shanshan Wu Jun Chen Pengcheng Ran Xuemin Shi 2011Neural Regeneration Research2011,6,12:4
113D-printed controllable gradient pore superwetting structures for high temperature efficient oil-water separation显示文摘Superwetting surfaces have the potential to address oil pollution in water,through their ability to separate the two.However,it remains a great challenge to fabricate stable and efficient separation structures using conventional manufacturing techniques.Furthermore,the materials traditionally used for oil-water separation are not stable at high temperature.Therefore,there is a need to develop stable,customizable structures to improve the performance of oil-water separation devices.In recent years,3D printing technology has developed rapidly,and breakthroughs have been made in the fabrication of complicated ceramic structures using this technology.Here,a ceramic material with a gradient pore structure and superhydrophobic/superoleophilic properties was prepared using 3D printing for high-efficiency oil-water separation.The gradient pore structure developed here can support a flux of up to 25434 L/m^(2)h,which is nearly 40%higher than that an analogous structure with straight pores.At 200℃,the oil-water separation performance was maintained at 97.4%.Furthermore,samples of the material exhibited outstanding mechanical properties,and chemical stability in a variety of harsh environments.This study provides an efficient,simple,and reliable method for manufacturing oil-water separation materials using 3D printing,and may have broader implications for both fundamental research and industrial applications.Zhipeng Jin Hui Mei Yuekai Yan Longkai Pan Hongxia Liu Shanshan Xiao Laifei Cheng 2021Journal of Materiomics2021,7,1:4
12New possible silver lining for pancreatic cancer therapy:Hydrogen sulfide and its donors显示文摘As one of the most lethal diseases,pancreatic cancer shows a dismal overall prognosis and high resistance to most treatment modalities.Furthermore,pancreatic cancer escapes early detection during the curable period because early symptoms rarely emerge and specific markers for this disease have not been found.Although combinations of new drugs,multimodal therapies,and adjuvants prolong survival,most patients still relapse after surgery and eventually die.Consequently,the search for more effective treatments for pancreatic cancer is highly relevant and justified.As a newly re-discovered mediator of gasotransmission,hydrogen sulfide(H2S)undertakes essential functions,encompassing various signaling complexes that occupy key processes in human biology.Accumulating evidence indicates that H2S exhibits bimodal modulation of cancer development.Thus,endogenous or low levels of exogenous H2S are thought to promote cancer,whereas high doses of exogenous H2S suppress tumor proliferation.Similarly,inhibition of endogenous H2S production also suppresses tumor proliferation.Accordingly,H2S biosynthesis inhibitors and H2S supplementation(H2S donors)are two distinct strategies for the treatment of cancer.Unfortunately,modulation of endogenous H2S on pancreatic cancer has not been studied so far.However,H2S donors and their derivatives have been extensively studied as potential therapeutic agents for pancreatic cancer therapy by inhibiting cell proliferation,inducing apoptosis,arresting cell cycle,and suppressing invasion and migration through exploiting multiple signaling pathways.As far as we know,there is no review of the effects of H2S donors on pancreatic cancer.Based on these concerns,the therapeutic effects of some H2S donors and NO-H2S dual donors on pancreatic cancer were summarized in this paper.Exogenous H2S donors may be promising compounds for pancreatic cancer treatment.Xu Hua Yan Xiao Jianan Sun Bao Ji Shanshan Luo Bo Wu Chao Zheng Peng Wang Fanxing Xu Keguang Cheng Huiming Hua Dahong Li 2021Acta Pharmaceutica Sinica B2021,11,5:4
13Silicon lithium-ion battery anode with enhanced performance: Multiple effects of silver nanoparticles显示文摘Silicon has been regarded as one of the most promising next generation lithium-ion battery anode. However, the poor cyclic stability of the Si based anode has severely limited its practical applications, which is even worse with high mass loading density(>1 mg cm^(-2)). A new concept has been developed to enhance the electrochemical performance of the Si nanoparticle anode. Silver nanoparticles are composited with the silicon nanoparticles in a facile way for the first time. It is found that the mechanical properties of the Si electrode have been significantly improved by the incorporation of the silver nanoparticles, leading to enhanced cyclic performance. With the Si/Ag mass ratio of 4:1, the reversible specific discharge capacity is retained as 1156 m A h g^(-1) after 100 cycles at 200 mA g^(-1), which is more than three times higher than that of the bare silicon(318 mA h g^(-1)). The rate performance has been effectively improved as well due to excellent electron conductivity of the silver nanoparticles.Shanshan Yin Qing Jia Xiuxia Zuo Shuang Xie Kai Fang Yonggao Xia Jinlong Li Bao Qiu Meimei Wang Jianzhen Ban Xiaoyan Wang Yi Zhang Ying Xiao Luyao Zheng Suzhe Liang Zhaoping Liu Cundong Wang Ya-Jun Cheng 2018Journal of Materials Science & Technology2018,34,10:4
14Metagenome analysis reveals potential microbial functions in topsoil of wheat-maize rotation system with five-year application of fertilizers显示文摘Fertilization mode affects soil quality and ecological health.The effects of four fertilization regimens on lignocellulose content,readily degradable carbohydrate decomposition,and potential microbial functions in the topsoil of a wheat-maize rotation system between 2012 and 2017 were investigated.The fertilization regimens of control(control NFNB),high chemical fertilizer(HCF),high biochar plus low chemical fertilizer(HBLCF),and biochar-based fertilizer(BBF)were compared on soil fundamental properties,microbial structure,and potential function in soil carbohydrate degradation based on metagenome analysis.The diversity of carbohydrate-active enzyme genes in the topsoil microbial consortia in the four trials was primarily distributed within the ten ecologically most dominant phyla.Application of BBF was associated with the lowest decline in total nitrogen and P2O5(2012-2017:6.5%and 28.1%,respectively)and the most effective carbohydrate decomposition(2015-2017:67.0%for cellulose and 59.9%for readily degradable carbohydrate).Carbohydrate transport and metabolism accounted for 6.0%of reads assigned functional classification under the BBF regimen.These findings reveal the ecologically functional diversity of topsoil microorganisms and suggest BBF application as a promising strategy for sustainable agriculture and beneficial to soil health.Yujun Shen Lixin Zhao Haibo Meng Hongsheng Cheng Jingtao Ding Jiarui Wang Shanshan Dong Xi Zhang Liqiu Song Shengwei Zheng 2019International Journal of Agricultural and Biological Engineering2019,12,6:3
15Mapping Toll-Like Receptor Signaling Pathway Genes of Zhikong Scallop(Chlamys farreri) with FISH显示文摘Toll-like receptor(TLR) signaling pathway plays a pivotal role in the innate immune system. Studies on TLR signaling pathway genes in Zhikong scallop(Chlamys farreri) have mainly focused on sequence analysis and expression profiling, no research has been carried out on their localization. The chromosomal position of TLR signaling pathway genes can be valuable for assemblying scallop genome and analysizing gene regulatory networks. In the present study, five key TLR signaling pathway genes(Cf TLR, Cf Myd88, Cf TRAF6, Cf NFκB, and Cf IκB) containing bacterial artificial chromosomes(BACs) were isolated and physically mapped through fluorescence in situ hybridization on five non-homologous chromosome pairs, showing a similar distribution to another five model species. The isolation and mapping of these key immune genes of C. farreri will aid to the research on innate immunity, assignment of interested genes to chromosomes, and integration of physical, linkage and cytogenetic maps of this species.ZHAO Bosong ZHAO Liang LIAO Huan CHENG Jie LIAN Shanshan LI Xuan HUANG Xiaoting BAO Zhenmin 2015Journal of Ocean University of China2015,14,6:3

17Basic fibroblast growth factor protects against influenza A virus-induced acute lung injury by recruiting neutrophils显示文摘Influenza virus (IAV)infection is a major cause of severe respiratory illness that affects almost every country in the world.IAV infections result in respiratory illness and even acute lung injury and death,but the underlying mechanisms responsible for IAV pathogenesis have not yet been fully elucidated.In this study,the basic fibroblast growth factor 2 (FGF2)level was markedly increased in H1N1 virus-infected humans and mice.FGF2,which is predominately derived from epithelial cells,recruits and activates neutrophils via the FGFR2-PI3K-AKT-NFKB signaling pathway.FGF2 depletion or knockout exacerbated influenzaassociated disease by impairing neutrophil recruitment and activation.More importantly,administration of the recombinant FGF2 protein significantly aUeviated the severity of IAV-induced lung injury and promoted the survival of IAV-infected mice.Based on the results from experiments in which neutrophils were depleted and adoptively transferred,FGF2 protected mice against IAV , infection by recruiting neutrophils.Thus,FGF2 plays a critical role in preventing IAV-induced lung injury,and FGF2 is a promising potential therapeutic target during IAV infection.Keyu Wang Chengcai Lai Tieling Li Cheng Wang Wei Wang Bing Ni Changqing Bai Shaogeng Zhang Lina Han Hongjing Gu Zhongpeng Zhao Yueqiang Duan Xiaolan Yang Li Xing Lingna Zhao Shanshan Zhou Min Xia Chengyu Jiang Xiliang Wang Penghui Yang 2018Journal of Molecular Cell Biology2018,10,6:3
18G protein-coupled receptors: structure- and function-based drug discovery显示文摘As one of the most successful therapeutic target families,G protein-coupled receptors(GPCRs)have experienced a transformation from random ligand screening to knowledge-driven drug design.We are eye-witnessing tremendous progresses made recently in the understanding of their structure-function relationships that facilitated drug development at an unprecedented pace.This article intends to provide a comprehensive overview of this important field to a broader readership that shares some common interests in drug discovery.Dehua Yang Qingtong Zhou Viktorija Labroska Shanshan Qin Sanaz Darbalaei Yiran Wu Elita Yuliantie Linshan Xie Houchao Tao Jianjun Cheng Qing Liu Suwen Zhao Wenqing Shui Yi Jjiang Ming-Wei Wang 2021Signal Transduction and Targeted Therapy2021,6,2:3
19Investigation and analysis of the linkage mechanism and whole process cost of livestock manure organic fertilizer显示文摘In recent years,the utilization of manure resources for livestock and poultry farming has attracted a widespread attention,and manure resources utilization models suitable for different regional characteristics have formed gradually.Among them,the production of organic fertilizer from animal manure is a vital utilization method.However,there are still some problems such as high production costs,difficult sales,and the unwillingness of farmers to use organic fertilizers which have affected the breeding cycle and the sustainability of manure treatment in livestock and poultry breeding.This article selected 371 organic fertilizer plants,related farms and farmers in China,focusing on the main links of the entire process of livestock manure-organic fertilizer-farm application,and studied the mode of animal manure collection by organic fertilizer plants.The costs of organic fertilizer production and farmland application were discussed.Moreover,suggestions were made for the promotion and implementation of large-scale organic fertilizers to make good utilization of manure resources in livestock and poultry farming.Shanshan Dong Bin Sui Yujun Shen Haibo Meng Lixin Zhao Jingtao Ding Haibin Zhou Xi Zhang Hongsheng Cheng Jian Wang Ran Li Liqiu Song Pengxiang Xu Ji Li 2020International Journal of Agricultural and Biological Engineering2020,13,2:2
20Ultrasensitive and stable all graphene field-effect transistor-based Hg^(2+)sensor constructed by using different covalently bonded RGO films assembled by different conjugate linking molecules显示文摘As'molecular bridge,'coupling agents can not only realize the covalent connection of composites,but also affect their properties,thus affecting the properties of devices based on them.Herein,leveraging differences in charge conduction properties of the(3-aminopropyl)trimethoxysilane and 5,10,15,20-tetrakis(4-aminophenyl)-21H,23H-porphine caused by conjugacy structural differences,two kinds of layerby-layer assembled smart carbon materials with different electrical properties are obtained at the same reduction temperature.The two graphene ultrathin films are then“planted”on Si/SiO2 substrates,respectively,as semiconductor layer and source/drain electrodes to fabricate an ultra-stable all-graphene field effect transistor(AG-FET).Enabled by the covalent functionalized configuration and the functionally diverse of coupling agents,the AG-FET obtained by this simple method won the high electrical characteristics,the hole,electron mobility,and the shelflife could reach 3.79 cm2/(V·s),3.78 cm2/(V·s),and 18months,respectively.In addition,good material stability and excellent device structure endow the device exceptional stability,electrical stability,and solvent resistance,improving its application prospect in solution phase sensing/detection.Such characteristics could be used to sense,transduce,and respond to external stimuli,especially in solution phase to monitor the important analytes,such as Hg^(2+)in a flowing sewage environment.We believe that such easy-to-manufacture AG-FETs with ultrahigh performance and ultrahigh stability could also show great application prospects in other significant fields.Mingyuan Sun Congcong Zhang Duo Chen Jian Wang Yanchen Ji Na Liang Haoyang Gao Shanshan Cheng Hong Liu 2021SmartMat2021,2,2:2
