5Allele-defined genome reveals biallelic differentiation during cassava evolution显示文摘Dear Editor,Generation of heterozygous genomes by hybridization between or within species can help maintain plant diversity and serve as a potential source of new species(Baek et al.,2018).Moreover,genomic heterozygosity is associated with genomic coadaptation,developmental stability,and heterosis.Accurate definition of alleles in haplotypes is necessary to precisely characterize allelic variation controlling agriculturally important traits(Shi et al.,2019).Currently,most released genomes have mosaic assembly of haplotypes due to random selection or collapse of alleles during genome assembly(Shi et al.,2019),which masked allelic variation and functional differentiation of divergent alleles in heterozygous species.Wei Hu Changmian Ji Haitao shi Zhe Liang Zehong Ding Jianqiu Ye Wenjun Ou Gang Zhou Weiwei Tie Yan Yan Jinghao Yang Xiaoying Yang Yunxie Wei Zhiqiang Jin Jianghui Xie Ming Peng Wenquan Wang Anping Guo Biyu Xu Jianchun Guo Songbi Chen Liming Ma Mingcheng Wang Yang Zhou Xiaolong Li Ruoxi Li Siyi Guo Xinhui Xiao Zhongqing Wan Feifei An Jie Zhang Qingyun Leng Yin Li Ray Ming Kaimian Li 2021Molecular Plant2021,14,6:8
6Whole genome sequencing of 10K patients with acute ischaemic stroke or transient ischaemic attack: design, methods and baseline patient characteristics显示文摘Background and purpose Stroke is the second leading cause of death worldwide and the leading cause of mortality and long-term disability in China,but its underlying risk genes and pathways are far from being comprehensively understood.We here describe the design and methods of whole genome sequencing(WGS)for 10914 patients with acute ischaemic stroke or transient ischaemic attack from the Third China National Stroke Registry(CNSR-III).Methods Baseline clinical characteristics of the included patients in this study were reported.DNA was extracted from white blood cells of participants.Libraries are constructed using qualified DNA,and WGS is conducted on BGISEQ-500 platform.The average depth is intended to be greater than 30×for each subject.Afterwards,Sentieon software is applied to process the sequencing data under the Genome Analysis Toolkit best practice guidance to call genotypes of single nucleotide variants(SNVs)and insertion-deletions.For each included subject,21 fingerprint SNVs are genotyped by MassARRAY assays to verify that DNA sample and sequencing data originate from the same individual.The copy number variations and structural variations are also called for each patient.All of the genetic variants are annotated and predicted by bioinformatics software or by reviewing public databases.Results The average age of the included 10914 patients was 62.2±11.3 years,and 31.4%patients were women.Most of the baseline clinical characteristics of the 10914 and the excluded patients were balanced.Conclusions The WGS data together with abundant clinical and imaging data of CNSR-III could provide opportunity to elucidate the molecular mechanisms and discover novel therapeutic targets for stroke.Si Cheng Zhe Xu Yang Liu Jinxi Lin Yong Jiang Yilong Wang Xia Meng Anxin Wang Xinying Huang Zhimin Wang Guohua Chen Songdi Wu Zhengchang Jia Yongming Chen Xuerong Qiu Jun Wu Binbin Song Weizhong Ji Zhongping An Wenjun Xue Lili Zhao Yu Geng Hongyan Li Hao Li Yongjun Wang 2021Stroke & Vascular Neurology2021,6,2:8
7Advances in crop phenotyping and multi-environment trials显示文摘Efficient evaluation of crop phenotypes is a prerequisite for breeding, cultivar adoption, genomics and phenomics study. Plant genotyping is developing rapidly through the use of high-throughput sequencing techniques,while plant phenotyping has lagged far behind and it has become the rate-limiting factor in genetics, large-scale breeding and development of new cultivars. In this paper,we consider crop phenotyping technology under three categories. The first is high-throughput phenotyping techniques in controlled environments such as greenhouses or specifically designed platforms. The second is a phenotypic strengthening test in semi-controlled environments, especially for traits that are difficult to be tested in multi-environment trials(MET), such as lodging, drought and disease resistance. The third is MET in uncontrolled environments, in which crop plants are managed according to farmer's cultural practices. Research and application of these phenotyping techniques are reviewed and methods for MET improvement proposed.Zhe LIU Fan ZHANG Qin MA Dong AN Lin LI Xiaodong ZHANG Dehai ZHU Shaoming LI 2015Frontiers of Agricultural Science and Engineering2015,2,1:7
8The Chinese Hα Solar Explorer(CHASE) mission: An overview显示文摘The Chinese Hα Solar Explorer(CHASE), dubbed “Xihe”—Goddess of the Sun, was launched on October 14, 2021 as the first solar space mission of China National Space Administration(CNSA). The CHASE mission is designed to test a newly developed satellite platform and to acquire the spectroscopic observations in the Hα waveband. The Hα Imaging Spectrograph(HIS)is the scientific payload of the CHASE satellite. It consists of two observational modes: raster scanning mode and continuum imaging mode. The raster scanning mode obtains full-Sun or region-of-interest spectral images from 6559.7 to 6565.9 ? and from 6567.8 to 6570.6 ? with 0.024 ? pixel spectral resolution and 1 min temporal resolution. The continuum imaging mode obtains photospheric images in continuum around 6689 ? with the full width at half maximum of 13.4 ?. The CHASE mission will advance our understanding of the dynamics of solar activity in the photosphere and chromosphere. In this paper, we present an overview of the CHASE mission including the scientific objectives, HIS instrument overview, data calibration flow, and first results of on-orbit observations.Chuan Li Cheng Fang Zhen Li MingDe Ding PengFei Chen Ye Qiu Wei You Yuan Yuan MinJie An HongJiang Tao XianSheng Li Zhe Chen Qiang Liu Gui Mei Liang Yang Wei Zhang WeiQiang Cheng JianXin Chen ChangYa Chen Qiang Gu QingLong Huang MingXing Liu ChengShan Han HongWei Xin ChangZheng Chen YiWei Ni WenBo Wang ShiHao Rao HaiTang Li Xi Lu Wei Wang Jun Lin YiXian Jiang LingJie Meng Jian Zhao 2022Science China(Physics,Mechanics & Astronomy)2022,65,8:7
9Protection of Mice from Lethal Endotoxemia by Chimeric Human BPI-Fcγ1 Gene Delivery显示文摘To evaluate the potentiality of applying gene therapy to endotoxemia in high-risk patients, we investigated the effects of transferring an adeno-associated virus serotype 2 (AAV2)-mediated BPI-Fcγ1 gene on protecting mice from challenge of lethal endotoxin. The chimeric BPI-Fcγ1 gene consists of two parts, one encods functional N-terminus (1 to 199 amino acidic residues) of human BPI, which is a bactericidal/permeability-increasing protein, and the other encodes Fc segment of human immunoglobulin G1(Fcγ1). Our results indicated that the target protein could be expressed and secreted into the serum of the gene-transferred mice. After lethal endotoxin challenge, the levels of endotoxin and TNF-αin the gene-transferred mice were decreased. The survival rate of the BPI-Fcγ1 gene-transferred mice was markedly increased. Our data suggest that AAV2-mediated chimeric BPI-Fcγ1 gene delivery can potentially be used clinically for the protection and treatment of endotoxemia and endotoxic shock in high-risk individuals.Chen Li Jing Li Zhe Lv Xinghua Guo Qinghua Chen Qingli Kong Yunqing An 2006Cellular & Molecular Immunology2006,3,3:7
10BPI_(700)-Fc∴1_(700) chimeric gene expression and its protective effect in a mice model of the lethal E. coli infection显示文摘Background Infections caused by gram-negative bacteria (GNB) often lead to high mortality in common clinical settings. The effect of traditional antibiotic therapy is hindered by drug-resistant bacteria and unneutralizable endotoxin. Few effective methods can protect high risk patients from bacterial infection. This study explored the protection of adeno-associated virus 2 (AAV2)-bacteriacidal permeability increasing protein 700 (BPI700) -fragment crystallizable gamma one 700 (Fc(1700) chimeric gene transferred mice against the minimal lethal dose (MLD) of E.coli and application of gene therapy for bacterial infection . Methods After AAV2-BPI700-Fc(1700 virus transfection,dot blotting and Western blotting were used to detect the target gene products in Chinese hamster ovary-K1 cells (CHO-K1cells). Reverse transcription-polymerase chain reaction and immunohistochemical assay were carried out to show the target gene expression in mice. Modified BPI-enzyme linked immunosorbent assay was used to identify the target gene products in murine serum. The protection of BPI700-Fc(1700 gene transferred mice was examined by survival rate after MLD E. coli challenge. Colony forming unit (CFU) count, limulus amebocyte lysate kit and cytokine kit were used to quantify the bacteria, the level of endotoxin, and proinflammatory cytokine. Results BPI1-199-Fc(1 protein was identified in the CHO-K1 cell culture supernatant, injected muscles and serum of the gene transferred mice. After MLD E. coli challenge, the survival rate of AAV2-BPI700-Fc(1700 gene transferred mice (36.7%) was significantly higher than that of AAV2-enhanced green fluorescent protein (AAV2- EGFP) gene transferred mice (3.3%) and PBS control mice (5.6%). The survival rate of AAV2-BPI700-Fc(1700 gene transferred mice treated with cefuroxime sodium was 65.0%. The bacterium number in main viscera, the levels of endotoxin and proinflammatory cytokine (tumor necrcsis factor-α and interleukin-1β) in serum of the AAV2-BPI700-Fc(1700 gene transferred mice were markedly lower than that of PBS control mice (P<0.01). Conclusions AAV2-BPI700-Fc(1700 gene transferred mice can resist MLD E. coli infection through expressing BPI1-199-Fc(1 protein. Our findings suggested that AAV2 mediated BPI700-Fc(1700 gene delivery could be used for protection and treatment of clinical GNB infection in high-risk individuals.KONG Qing-li GUAN Yuan-zhi JING Xue-fang LI Chen GUO Xiang-hua LU Zhe AN Yun-qing 2006Chinese Medical Journal2006,,6:5

12Mesenchymal stem cell treatment improves outcome of COVID-19 patients via multiple immunomodulatory mechanisms显示文摘The infusion of coronavirus disease 2019(COVID-19)patients with mesenchymal stem cells(MSCs)potentially improves clinical symptoms,but the underlying mechanism remains unclear.We conducted a randomized,single-blind,placebo-controlled(29 patients/group)phase II clinical trial to validate previous findings and explore the potential mechanisms.Patients treated with umbilical cord-derived MSCs exhibited a shorter hospital stay(P=0.0198)and less time required for symptoms remission(P=0.0194)than those who received placebo.Based on chest images,both severe and critical patients treated with MSCs showed improvement by day 7(P=0.0099)and day 21(P=0.0084).MSC-treated patients had fewer adverse events.MSC infusion reduced the levels of C-reactive protein,proinflammatory cytokines,and neutrophil extracellular traps(NETs)and promoted the maintenance of SARS-CoV-2-specific antibodies.To explore how MSCs modulate the immune system,we employed single-cell RNA sequencing analysis on peripheral blood.Our analysis identified a novel subpopulation of VNN2+hematopoietic stem/progenitorlike(HSPC-like)cells expressing CSF3R and PTPRE that were mobilized following MSC infusion.Genes encoding chemotaxis factors—CX3CR1 and L-selectin—were upregulated in various immune cells.MSC treatment also regulated B cell subsets and increased the expression of costimulatory CD28 in T cells in vivo and in vitro.In addition,an in vivo mouse study confirmed that MSCs suppressed NET release and reduced venous thrombosis by upregulating kindlin-3 signaling.Together,our results underscore the role of MSCs in improving COVID-19 patient outcomes via maintenance of immune homeostasis.Rongjia Zhu Tingdong Yan Yingmei Feng Yan Liu Hongcui Cao Gongxin Peng Yanlei Yang Zhen Xu Jingqi Liu Wei Hou Xiaoyue Wang Zhe Li Luchan Deng Shihua Wang Jing Li Qin Han Hongling Li Guangliang Shan Yinghao Cao Xingyan An Jianshe Yan Zhonghui Zhang Huafei Li Xuebin Qu Jiaqi Zhu Shumin Zhou Jiao Wang Fengchun Zhang Jinming Gao Ronghua Jin Dayong Xu Yan-Qing Ma Tao Huang Shuang Peng Zhi Zheng Ilia Stambler Eric Gilson Lee Wei Lim Alexey Moskalev Antonio Cano Sasanka Chakrabarti Brun Ulfhake Huanxing Su Haoying Xu Sihuan Xu Feng Wei Holly MBrown-Borg Kyung-Jin Min Georgina Ellison-Hughes Calogero Caruso Kunlin Jin Robert Chunhua Zhao 2021Cell Research2021,31,12:5
13FeNi nanoparticles on Mo_(2)TiC_(2)T_(x)MXene@nickel foam as robust electrocatalysts for overall water splitting显示文摘The development of cost-effective electrocatalysts for overall water splitting is highly desirable,remaining a critical challenge at current stage.Herein,a class of composite FeNi@MXene(Mo_(2)TiC_(2)T_(x))@nickel foam(NF)has been synthesized through introducing Fe2+ions and in-situ combining with surface nickel atoms on nickel foam.The obtained FeNi@Mo_(2)TiC_(2)T_(x)@NF exhibited high activity with overpotentials of 165 and 190 mV for the hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)at a current density of 10 mA·cm^(-2),respectively.The synergetic effects of Mo_(2)TiC_(2)T_(x)and FeNi nanoalloys lead to increasing catalytic activities,where MXene provides high active surface area and rich active sites for HER,and FeNi nanoalloys promote the OER.Theoretical simulation of electron exchange capacity between FeNi and MXene in FeNi@Mo_(2)TiC_(2)T_(x)catalyst shows that electrons transferred from surface Mo atoms to the interface between FeNi and MXene,indicating that the electrons are accumulated near the FeNi nanoparticles.This kind of electronic distribution facilitates the formation of intermediate of NiOOH.Correspondingly,(H++e-)is more inclined onto Mo-Ni interfaces for HER.The Gibbs free energy changes for H*to HER and potential-limiting step for-OOH intermediate in OER over FeNi@Mo_(2)TiC_(2)T_(x)are much less than those on bare MXene.The catalyst can be further used for overall water splitting in alkaline solution,realizing a current density of 50 mA·cm^(-2)at 1.74 V.This work provides a facile strategy to achieve efficient and cheap catalysts for new energy production.Jiayang Wang Peilei He Yongli Shen Linxiu Dai Zhe Li Yue Wu Changhua An 2021Nano Research2021,14,10:5

15Downregulation of ceramide synthase 1 promotes oral cancer through endoplasmic reticulum stress显示文摘C18 ceramide plays an important role in the occurrence and development of oral squamous cell carcinoma.However,the function of ceramide synthase 1,a key enzyme in C18 ceramide synthesis,in oral squamous cell carcinoma is still unclear.The aim of our study was to investigate the relationship between ceramide synthase 1 and oral cancer.In this study,we found that the expression of ceramide synthase 1 was downregulated in oral cancer tissues and cell lines.In a mouse oral squamous cell carcinoma model induced by 4-nitroquinolin-1-oxide,ceramide synthase 1 knockout was associated with the severity of oral malignant transformation.Immunohistochemical studies showed significant upregulation of PCNA,MMP2,MMP9,and BCL2 expression and downregulation of BAX expression in the pathological hyperplastic area.In addition,ceramide synthase 1 knockdown promoted cell proliferation,migration,and invasion in vitro.Overexpression of CERS1 obtained the opposite effect.Ceramide synthase 1 knockdown caused endoplasmic reticulum stress and induced the VEGFA upregulation.Activating transcription factor 4 is responsible for ceramide synthase 1 knockdown caused VEGFA transcriptional upregulation.In addition,mild endoplasmic reticulum stress caused by ceramide synthase 1 knockdown could induce cisplatin resistance.Taken together,our study suggests that ceramide synthase 1 is downregulated in oral cancer and promotes the aggressiveness of oral squamous cell carcinoma and chemotherapeutic drug resistance.Wen Chen Chenzhou Wu Yafei Chen Yuhao Guo Ling Qiu Zhe Liu Haibin Sun Siyu Chen Zijian An Zhuoyuan Zhang Yi Li Longjiang Li 2021International Journal of Oral Science2021,13,1:3

17Identification of maize seed varieties based on near infrared reflectance spectroscopy and chemometrics显示文摘False seeds can often be seen in the maize seed market,leading to a serious decline in maize yield.Those existing variety identification methods are expensive,time consuming,and destructive to seeds.The aim of this study is to develop a cheap,fast and non-destructive method which can robustly identify large amounts of maize seed varieties based on near-infrared reflectance spectroscopy(NIRS)and chemometrics.Because it is difficult to establish models for every variety in the market,this study mainly investigated the performance of models based on a large number of samples(more than 40 major varieties in the market).The reflectance spectra of maize seeds were collected by two modes(bulk kernels mode and single kernel mode).Both collection modes can be applied to identification,but only the single kernel mode can be applied to purity sorting.The spectra were pretreated with smoothing,the first derivative and vector normalization;and then principal component analysis(PCA),linear discriminant analysis(LDA)and biomimetic pattern recognition(BPR)were applied to establish identification models.The environmental factors such as producing areas and years have a significant influence on the performance of the models.Therefore,the method to improve the robustness of the models was investigated in this study.New indexes(correct acceptance degree(CAD),correct rejection degree(CRD)and correct degree(CD))were defined to analyze the performance of the models more accurately.Finally,the models obtained a mean correct discrimination rate of over 90%,and exhibited robust properties for samples harvested from different areas and years.The results showed that NIR technology combined with chemometrics methods such as PCA,LDA,and BPR could be a suitable and alternative technique to identify the authenticity of maize seed varieties.Yongjin Cui Lanjun Xu Dong An Zhe Liu Jiancheng Gu Shaoming Li Xiaodong Zhang Dehai Zhu 2018International Journal of Agricultural and Biological Engineering2018,11,2:3
18Protection of Immuno-Compromised Mice from Lethal Infection of Klebsiella pneumonia by rAAV2-BPI23-Fcγ1 Gene Transfer显示文摘In previous research, chimerical BPI23-Fcγ1 gene which consisted of human bactericidal/permeability increasing protein (BPI) gene of encoding the functional N terminus (amino acid residues 1 to 199) of human BPI and Fcγ1 gene of encoding the Fc segment of human immunoglobulin G1 was successfully reconstructed within a recombinant adeno-associated virus serotype 2 (rAAV2) vector as rAAV2-BPI23-Fcγ1. Here, to evaluate the potentiality of applying gene therapy to gram negative bacterial (GNB) infection in high-risk patients, we investigated protection of immuno-compromised mice and immunocompetent mice from challenge with minimal lethal dose (MLD) Klebsiella pneumonia infection after rAAV2-BPI23-Fcγ1 gene transferred. The results showed that the survival rate of rAAV2-BPI23-Fcγ1 transferred immunocompetent mice as well as immuno-compromised mice (40.0% and 44.4%, respectively) were significantly higher than that of corresponding control mice (6.7% and 4.4%, respectively); the bacteria counting, level of endotoxin and proinflammatory cytokines in the rAAV2-BPI23- Fcγ1 transferred immuno-compromised mice were markedly lower than that of rAAV2-EGFP and rAAV2-Null transferred immuno-compromised mice. Our data suggest that rAAV2-BPI23-Fcγ1 gene transferring offered immuno-compromised mice with resistance against GNB infection, so it is quite potential in preventing GNB infection of clinical high-risk patients.Jing Li Qingli Kong Zhe Lv Yuanzhi Guan Yong Qiu Chen Li Mingjie Sun Zhenlong Liu Yunqing An 2008Cellular & Molecular Immunology2008,5,6:2
