| 1 | Polyamine Accumulation in Transgenic Tomato Enhances the Tolerance to High Temperature Stress显示文摘Polyamines play an important role in plant response to abiotic stress.S-adenosyl-l-methionine decarboxylase(SAMDC) is one of the key regulatory enzymes in the biosynthesis of polyamines.In order to better understand the effect of regulation of polyamine biosynthesis on the tolerance of high-temperature stress in tomato,SAMDC cDNA isolated from Saccharomyces cerevisiae was introduced into tomato genome by means of Agrobacterium tumefaciens through leaf disc transformation.Transgene and expression was confirmed by Southern and Northern blot analyses,respectively.Transgenic plants expressing yeast SAMDC produced 1.7-to 2.4-fold higher levels of spermidine and spermine than wild-type plants under high temperature stress,and enhanced antioxidant enzyme activity and the protection of membrane lipid peroxidation was also observed.This subsequently improved the efficiency of CO2 assimilation and protected the plants from high temperature stress,which indicated that the transgenic tomato presented an enhanced tolerance to high temperature stress(38℃) compared with wild-type plants.Our results demonstrated clearly that increasing polyamine biosynthesis in plants may be a means of creating high temperature-tolerant germplasm. | Lin Cheng Yijing Zou Shuli Ding Jiajing Zhang Xiaolin Yu Jiashu Cao Gang Lu | 2009 | Journal of Integrative Plant Biology2009，51，5： | 16 |
| 2 | Humoral immune response to circulating SARS-CoV-2 variants elicited by inactivated and RBD-subunit vaccines显示文摘SARS-CoV-2 variants could induce immune escape by mutations on the receptor-binding domain(RBD)and N-terminal domain(NTD).Here we report the humoral immune response to circulating SARS-CoV-2 variants,such as 501Y.V2(B.1.351),of the plasma and neutralizing antibodies(NAbs)elicited by CoronaVac(inactivated vaccine),ZF2001(RBD-subunit vaccine)and natural infection.Among 86 potent NAbs identified by high-throughput single-cell VDJ sequencing of peripheral blood mononuclear cells from vaccinees and convalescents,near half anti-RBD NAbs showed major neutralization reductions against the K417N/E484K/N501Y mutation combination,with E484K being the dominant cause.VH3-53/VH3-66 recurrent antibodies respond differently to RBD variants,and K417N compromises the majority of neutralizing activity through reduced polar contacts with complementarity determining regions.In contrast,the 242–244 deletion(242–244Δ)would abolish most neutralization activity of anti-NTD NAbs by interrupting the conformation of NTD antigenic supersite,indicating a much less diversity of anti-NTD NAbs than anti-RBD NAbs.Plasma of convalescents and CoronaVac vaccinees displayed comparable neutralization reductions against pseudo-and authentic 501Y.V2 variants,mainly caused by E484K/N501Y and 242–244Δ,with the effects being additive.Importantly,RBD-subunit vaccinees exhibit markedly higher tolerance to 501Y.V2 than convalescents,since the elicited anti-RBD NAbs display a high diversity and are unaffected by NTD mutations.Moreover,an extended gap between the third and second doses of ZF2001 leads to better neutralizing activity and tolerance to 501Y.V2 than the standard three-dose administration.Together,these results suggest that the deployment of RBD-vaccines,through a third-dose boost,may be ideal for combating SARS-CoV-2 variants when necessary,especially for those carrying mutations that disrupt the NTD supersite. | Yunlong Cao Ayijiang Yisimayi Yali Bai Weijin Huang Xiaofeng Li Zhiying Zhang Tianjiao Yuan Ran An Jing Wang Tianhe Xiao Shuo Du Wenping Ma Liyang Song Yongzheng Li Xiang Li Weiliang Song Jiajing Wu Shuo Liu Xuemei Li Yonghong Zhang Bin Su Xianghua Guo Yangyang Wei Chuanping Gao Nana Zhang Yifei Zhang Yang Dou Xiaoyu Xu Rui Shi Bai Lu Ronghua Jin Yingmin Ma Chengfeng Qin Youchun Wang Yingmei Feng Junyu Xiao Xiaoliang Sunney Xie | 2021 | Cell Research2021，31，7： | 12 |
| 3 | Global Dynamic Molecular Profiling of Stomatal Lineage Cell Development by Single-Cell RNA Sequencing显示文摘The regulation of stomatal lineage cell development has been extensively investigated.However,a comprehensive characterization of this biological process based on single-cell transcriptome analysis has not yet been reported.In this study,we performed RNA sequencing on 12844 individual cells from the cotyledons of 5-day-old Arabidopsis seedlings.We identified 11 cell clusters corresponding mostly to cells at specific stomatal developmental stages using a series of marker genes.Comparative analysis of genes with the highest variable expression among these cell clusters revealed transcriptional networks that regulate development from meristemoid mother cells to guard mother cells.Examination of the developmental dynamics of marker genes via pseudo-time analysis revealed potential interactions between these genes.Collectively,our study opens the door for understanding how the identified novel marker genes participate in the regulation of stomatal lineage cell development. | Zhixin Liu Yaping Zhou Jinggong Guo Jiaoai Li Zixia Tian Zhinan Zhu Jiajing Wang Rui Wu Bo Zhang Yongjian Hu Yijing Sun Yan Shangguan Weiqiang Li Tao Li Yunhe Hu Chenxi Guo Jean-David Rochaix Yuchen Miao Xuwu Sun | 2020 | Molecular Plant2020，13，8： | 11 |
| 4 | Osteoblast/fibroblast coculture derived bioactive ECM with unique matrisome profile facilitates bone regeneration显示文摘Extracellular matrix(ECM)with mimetic tissue niches was attractive to facilitate tissue regeneration in situ via recruitment of endogenous cells and stimulation of self-healing process.However,how to engineer the complicate tissue specific ECM with unique matrisome in vitro was a challenge of ECM-based biomaterials in tissue engineering and regenerative medicine.Here,we introduced coculture system to engineer bone mimetic ECM niche guided by cell-cell communication.In the cocultures,fibroblasts promoted osteogenic differentiation of osteoblasts via extracellular vesicles.The generated ECM(MN-ECM)displayed a unique appearance of morphology and biological components.The advantages of MN-ECM were demonstrated with promotion of multiple cellular behaviors(proliferation,adhesion and osteogenic mineralization)in vitro and bone regeneration in vivo.Moreover,proteomic analysis was used to clarify the molecular mechanism of MN-ECM,which revealed a specific matrisome signature.The present study provides a novel strategy to generate ECM with tissue mimetic niches via cell-cell communication in a coculture system,which forwards the development of tissue-bioactive ECM engineering along with deepening the understanding of ECM niches regulated by cells for bone tissue engineering. | Mei Li Anqi Zhang Jiajing Li Jing Zhou Yanan Zheng Chi Zhang Dongdong Xia Haijiao Mao Jiyuan Zhao | 2020 | Bioactive Materials2020，5，4： | 7 |
| 5 | PdAg bimetallic electrocatalyst for highly selective reduction of CO2 with low COOH^* formation energy and facile CO desorption显示文摘For electrocatalytic reduction of CO2 to CO,the stabilization of intermediate COOH^* and the desorption of CO^* are two key steps.Pd can easily stabilize COOH^*,whereas the strong CO^* binding to Pd surface results in severe poisoning,thus lowering catalytic activity and stability for CO2 reduction.On Ag surface,CO^* desorbs readily,while COOH^* requires a relatively high formation energy,leading to a high overpotential.In light of the above issues,we successfully designed the PdAg bimetallic catalyst to circumvent the drawbacks of sole Pd and Ag.The PdAg catalyst with Ag-terminated surface not only shows a much lower overpotential(-0.55 V with CO current density of 1 mA/cm^2)than Ag(−0.76 V),but also delivers a CO/H2 ratio 18 times as high as that for Pd at the potential of-0.75 V vs.RHE.The issue of CO poisoning is significantly alleviated on Ag-terminated PdAg surface,with the stability well retained after 4h electrolysis at-0.75 V vs.RHE.Density functional theory(DFT)calculations reveal that the Ag-terminated PdAg surface features a lowered formation energy for COOH^* and weakened adsorption for CO^*,which both contribute to the enhanced performance for CO2 reduction. | Rui Lin Xuelu Ma Weng-Chon Cheong Chao Zhang Wei Zhu Jiajing Pei Kaiyue Zhang Bin Wang Shiyou Liang Yuxi Liu Zhongbin Zhuang Rong Yu Hai Xiao Jun Li Dingsheng Wang Qing Peng Chen Chen Yadong Li | 2019 | Nano Research2019，12，11： | 7 |
| 6 | Far-field super-resolution imaging by nonlinearly excited evanescent waves显示文摘Abbe’s resolution limit,one of the best-known physical limitations,poses a great challenge for any wave system in imaging,wave transport,and dynamics.Originally formulated in linear optics,the Abbe limit can be broken using nonlinear optical interactions.We extend the Abbe theory into a nonlinear regime and experimentally demonstrate a far-field,label-free,and scan-free super-resolution imaging technique based on nonlinear four-wave mixing to retrieve near-field scattered evanescent waves,achieving a sub-wavelength resolution ofλ∕5.6.This method paves the way for numerous new applications in biomedical imaging,semiconductor metrology,and photolithography. | Zhihao Zhou Wei Liu Jiajing He Lei Chen Xin Luo Dongyi Shen Jianjun Cao Yaping Dan Xianfeng Chen Wenjie Wan | 2021 | Advanced Photonics2021，3，2： | 6 |
| 7 | Pyramiding favorable alleles in an elite wheatvariety in one generation by CRISPR-Cas9-mediated multiplex gene editing显示文摘Dear Editor,Common wheat(Triticum aestivum,2n=6x=42,AABBDD)is amajor staple crop consumed by more than 30%of the world’spopulation.It is the main source of cereal-based processed prod-ucts,such as bread,cookies,pasta,and noodles.Althoughwheat production increased by 10-fold following the Green revo-lution and maker-assisted breeding over the past decades,it isstill facing unprecedented challenges in the context of globalclimate changes,growing world population,decreased farm-lands,as well as water shortages in arid and semi-arid lands.Meanwhile,the functional redundancy of genes in hexaploidywheat makes a forward genetics approach to select a desiredphenotype,especially for pyramiding of several agronomicallyimportant traits in a modern variety,very time-consuming and in some cases,impossible because of gene linkage or genedrag. | Jinman Luo Shaoya Li Jiajing Xu Lei Yan Youzhi Ma Lanqin Xia | 2021 | Molecular Plant2021，14，6： | 6 |
| 8 | Genomic surveillance of coxsackievirus A10 reveals genetic features and recent appearance of genogroup D in Shanghai,China,2016–2020显示文摘Coxsackievirus A10(CVA10)is one of the major causative agents of hand,foot and mouth disease(HFMD).To investigate the epidemiological characteristics as well as genetic features of CVA10 currently circulating in Shanghai,China,we collected a total of 9,952 sporadic HFMD cases from January 2016 to December 2020.In the past five years,CVA10 was the fourth prevalent causatives associated with HFMD in Shanghai and the overall positive rate was 2.78%.The annual distribution experienced significant fluctuations over the past five years.In addition to entire VP1 sequencing,complete genome sequencing and recombination analysis of CVA10 isolates in Shanghai were further performed.A total of 64 near complete genomes and 11 entire VP1 sequences in this study combined with reference sequences publicly available were integrated into phylogenetic analysis.The CVA10sequences in this study mainly belonged to genogroup C and presented 91%-100%nucleotide identity with other Chinese isolates based on VP1 region.For the first time,our study reported the appearance of CVA10 genogroup D in Chinese mainland,which had led to large-scale outbreaks in Europe previously.The recombination analysis showed the recombination break point located between 5,100 nt and 6,700 nt,which suggesting intertypic recombination with CVA16 genogroup D.To conclusion,CVA10 genogroup C was the predominant genogroup in Shanghai during 2016-2020.CVA10 recombinant genogroup D was firstly reported in circulating in Chinese mainland.Continuous surveillance is needed to better understand the evolution relationships and transmission pathways of CVA10 to help to guide disease control and prevention. | Jiayu Wang Jiajing Liu Fanghao Fang Jiajin Wu Tianjiao Ji Yuying Yang Ling Liu Chongshan Li Wanju Zhang Xi Zhang Zheng Teng | 2022 | Virologica Sinica2022，37，2： | 5 |
| 9 | Metal-organic frameworks nanoswitch:Toward photo-controllable endo/lysosomal rupture and release for enhanced cancer RNA interference显示文摘Endo/lysosomal escape and gene release are two critical bottlenecks in gene delivery.Herein,a novel photo-controllable metal-organic frameworks(MOFs)nanoswitch is rationally designed for enhancing small interfering RNA(siRNA)delivery.One single laser triggers the“off-to-on”switching of MOFs nanocomplexes,inducing significant siRNA release accompanied by rapid MOFs dissociation into protonatable 2-methylimidazalo and osmotic rupturing Zn2+ions,which cooperatively contribute to remarkable endo/lysosomal rupture(∼90%).The simultaneous endo/lysosomal rupture and release enable a high spatio-temporal control on RNA interference for effective cancer therapy.Notably,the“off-to-on”switching also activates fluorescence recovery for real-time monitoring siRNA delivery.The nanoswitch could easily be extended to deliver other therapeutic agents(e.g.,DNA,protein,anticancer drug)for overcoming endo/lysosomal entrapment. | Gan Lin Yang Zhang Long Zhang Junqing Wang Ye Tian Wen Cai Shangui Tang Chengchao Chu JiaJing Zhou Peng Mi Xiaoyuan Chen Gang Liu | 2020 | Nano Research2020，13，1： | 5 |
| 10 | Autophagy enhanced by curcumin ameliorates inflammation in atherogenesis via the TFEB-P300-BRD4 axis显示文摘Disturbance of macrophage-associated lipid metabolism plays a key role in atherosclerosis.Crosstalk between autophagy deficiency and inflammation response in foam cells(FCs) through epigenetic regulation is still poorly understood. Here, we demonstrate that in macrophages, oxidized lowdensity lipoprotein(ox-LDL) leads to abnormal crosstalk between autophagy and inflammation,thereby causing aberrant lipid metabolism mediated through a dysfunctional transcription factor EB (TFEB)-P300-bromodomain-containing protein 4(BRD4) axis. ox-LDL led to macrophage autophagy deficiency along with TFEB cytoplasmic accumulation and increased reactive oxygen species generation. This activated P300 promoted BRD4 binding on the promoter regions of inflammatory genes, consequently contributing to inflammation with atherogenesis. Particularly, ox-LDL activated BRD4-dependent super-enhancer associated with liquid-liquid phase separation(LLPS) on the regulatory regions of inflammatory genes. Curcumin(Cur) prominently restored FCs autophagy by promoting TFEB nuclear translocation, optimizing lipid catabolism, and reducing inflammation. The consequences of P300 and BRD4 on super-enhancer formation and inflammatory response in FCs could be prevented by Cur. Furthermore, the anti-atherogenesis effect of Cur was inhibited by macrophage-specific Brd4 overexpression or Tfeb knock-out in Apoe knock-out mice via bone marrow transplantation. The findings identify a novel TFEB-P300-BRD4 axis and establish a new epigenetic paradigm by which Cur regulates autophagy, inhibits inflammation, and decreases lipid content. | Xuesong Li Ruigong Zhu Hong Jiang Quanwen Yin Jiaming Gu Jiajing Chen Xian Ji Xuan Wu Haiping Fu Hui Wang Xin Tang Yuanqing Gao Bingjian Wang Yong Ji Hongshan Chen | 2022 | Acta Pharmaceutica Sinica B2022，12，5： | 4 |
| 11 | The IAA-and ABA-responsive transcription factor CgMYB58 upregulates lignin biosynthesis and triggers juice sac granulation in pummelo显示文摘In citrus,lignin overaccumulation in the juice sac results in granulation and an unpleasant fruit texture and taste.By integrating metabolic phenotyping and transcriptomic analyses,we found 702 differentially expressed genes(DEGs),including 24 transcription factors(TFs),to be significantly correlated with lignin content.CgMYB58 was further identified as a critical R2R3 MYB TF involved in lignin overaccumulation owing to its high transcript levels in Huanong Red-fleshed pummelo(HR,Citrus grandis)fruits.Transient expression of CgMYB58 led to an increase in the lignin content in the pummelo fruit mesocarp,whereas its stable overexpression significantly promoted lignin accumulation and upregulated 19 lignin biosynthetic genes.Among these genes,CgPAL1,CgPAL2,Cg4CL1,and CgC3H were directly modulated by CgMYB58 through interaction with their promoter regions.Moreover,we showed that juice sac granulation in pummelo fruits could be affected by indole-3-acetic acid(IAA)and abscisic acid(ABA)treatments.In HR pummelo,ABA significantly accelerated this granulation,whereas IAA effectively inhibited this process.Taken together,these results provide novel insight into the lignin accumulation mechanism in citrus fruits.We also revealed the theoretical basis via exogenous IAA application,which repressed the expression of CgMYB58 and its target genes,thus alleviating juice sac granulation in orchards. | Meiyan Shi Xiao Liu Haipeng Zhang Zhenyu He Hongbin Yang Jiajing Chen Jia Feng Wenhui Yang Youwu Jiang Jia-Long Yao Cecilia Hong Deng Juan Xu | 2020 | Horticulture Research2020，7，1： | 4 |
| 12 | Enrichment factors and sweep spot evaluation of Jurassic tight oil in central Sichuan Basin,SW China显示文摘The secondary migration mechanism,enrichment factors of Jurassic tight oil in central Sichuan Basin were well investigated through physical simulation experiment of reservoir formation,casting and fluorescent thin sections,field emission scanning electron microscope(FESEM)and environment scanning electron microscope(ESEM).The results show that migration of Jurassic tight oil in central Sichuan Basin is a low-velocity non-Darcy flow through low-efficient migration path under the huge migration driving force,and has three migration and seepage stages,i.e.viscous flow stage,nonlinear seepage stage,and quasi-liner seepage stage.Microscopically,the migration pathway of tight oil is the porefracture composite conduction;macroscopically,the migration mode of tight oil is the large-scale shortedistance migration.Distribution of favorable zones of tight oil is controlled by distribution of high-quality source rocks.The hydrocarbon-generation strength of 0.4106 t/km2 can be as a threshold to determine favorable zone of tight oil in the study area.The reservoirs with high permeability and high porosity can form tight oil sweet spots,and the development degree of fractures is closely related to well with high yield of tight oil well. | Zhenglian Pang Shizhen Tao Qin Zhang Tianshu Zhang Jiajing Yang Jianwei Fan Miao Yuan | 2019 | Petroleum Research2019，4，4： | 3 |
| 13 | PtNi-W/C with Atomically Dispersed Tungsten Sites Toward Boosted ORR in Proton Exchange Membrane Fuel Cell Devices显示文摘The performance of proton exchange membrane fuel cells is heavily dependent on the microstructure of electrode catalyst especially at low catalyst loadings.This work shows a hybrid electrocatalyst consisting of PtNi-W alloy nanocrystals loaded on carbon surface with atomically dispersed W sites by a two-step straightforward method.Single-atomic W can be found on the carbon surface,which can form protonic acid sites and establish an extended proton transport network at the catalyst surface.When implemented in membrane electrode assembly as cathode at ultra-low loading of 0.05 mgPt cm^(−2),the peak power density of the cell is enhanced by 64.4%compared to that with the commercial Pt/C catalyst.The theoretical calculation suggests that the single-atomic W possesses a favorable energetics toward the formation of*OOH whereby the intermediates can be efficiently converted and further reduced to water,revealing a interfacial cascade catalysis facilitated by the single-atomic W.This work highlights a novel functional hybrid electrocatalyst design from the atomic level that enables to solve the bottle-neck issues at device level. | Huawei Wang Jialong Gao Changli Chen Wei Zhao Zihou Zhang Dong Li Ying Chen Chenyue Wang Cheng Zhu Xiaoxing Ke Jiajing Pei Juncai Dong Qi Chen Haibo Jin Maorong Chai Yujing Li | 2023 | Nano-Micro Letters2023，15，9： | 3 |
| 14 | Amorphous M0S2 confined in nitrogen-doped porous carbon for improved electrocatalytic stability toward hydrogen evolution reaction显示文摘Developing non-precious metal catalysts with high activity and stability for electrochemical hydrogen evolution reaction(HER)is of great significance in both scie nee and tech no logy.In this work,N-doped CMK-3,which was prepared with a casting method using SBA-15 as thehard template and ammonia as the nitrogen source,has been utilized to hold MoS2 and restrict its growth to form MoS2@N-CMK-3 composite.As a result,M0S2 was found to have poorly crystallized and the limited space of porous N-CMK-3 made its size much small.Then there are moreactive sites in MoS2.Accordingly,MoS2@N-CMK-3 has exhibited good electrocatalytic performance toward HER in acids with a quite small Tafelslope of 32 mV·dec^-1.And more importantly,compared to MoS2@CMK-3,its stability has been greatly improved,which can be attributedto the interaction between M0S2 and nitrogen atoms avoiding aggregation and mass loss.This work provides an idea that doping a porouscarbon support with nitrogen is an effective way to enhance the stability of the catalyst. | Shaojie Lu Wenjing Wang Shengshuang Yang Wei Chen Zhongbin Zhuang Wenjing Tang Caihong He Jiajing Qian Dekun Ma Yun Yang Shaoming Huang | 2019 | Nano Research2019，12，12： | 2 |

| 16 | Broadband Acoustic Vibration Sensor Based on Cladding-Mode Resonance of Double-Cladding Fiber显示文摘We have proposed and demonstrated a double-cladding fiber (DCF) with cladding?mode resonance property for broadband acoustic vibration sensing. Since the fundamental mode in the core waveguide is able to be coupled to LP05 mode in the tube waveguide once the phase-matching condition is fulfilled, the transmission spectrum can exhibit a dip with a large extinction ratio. An acoustic vibration could induce the wavelength shift of such transmission spectrum, so that the intensity variation at a wavelength near the dip is coded with the information of the acoustic vibration signal. By demodulating the response of intensity variation, the frequency of the applied acoustic vibration signal can be recovered. Such a DCF-based sensor with an intensity modulation could measure the acoustic vibration with a broadband frequency range from 1 Hz to 400 kHz and exhibits the maximum signal-to-noise ratio (SNR) of ?80.79 dB when the vibration frequency is 20 kHz. The obtained results show that the proposed DCF-based acoustic vibration sensor has a potential application in environmental assessment, structural damage detection, and health monitoring. | Guanghui SUI Huanhuan LIU Fufei PANG Jiajing CHENG Tingyun WANG | 2019 | Photonic Sensors2019，9，3： | 2 |

| 18 | Formation characteristics and resource potential of Jurassic tight oil in Sichuan Basin显示文摘Through test analysis of large amount of cores,rock fragments and crude oil samples,and in combination with dynamic data of production from 456 oil wells,hydrocarbon generation potentials of four major source rocks and accumulation characteristics of three major pay layers in the Jurassic of Sichun Basin were well investigated.Results indicated that source rocks in the Lianggaoshan Formation,the Da'anzhai Member and the Dongyuemiao Member mainly generated oil,and those in the Zhenzhuchong Member dominantly generated gas;the organic-rich source rocks controlled distribution of sweet spots of tight oil,and most industrial oil wells were located at the area with high-quality source rocks(TOC>1.2%);and micron-sized pore throats were effective storage space,and fractures played a key role in initial high yield.Jurassic tight oil in the Sichuan Basin was characterized by light oil,high gas-oil ratio and abnormal high pressure,which were favorable for tight oil flow and output.Four methods(i.e.,small bin method,resource abundance analogy method,EUR analogy method and total organic carbon method)were used to estimate Jurassic oil in-place in the Sichuan Basin which ranged from 2×10^(9) to 3×10^(9) t.Through analysis of main controlling factors of resource enrichment,the grading criteria were established for the evaluation of oil in-place in the Sichuan Basin.Through the small bin method,the oil in-place of Type I,Type II and Type III was 1.611×10^(9)t,0.477×10^(9)t and 0.289×10^(9)t,respectively.It was predicted that the largest exploration potential of the Da'anzhai Member was in the Nanchong-Suining area and the east of Liangping area,the most favorable exploration area of the Lianggaoshan Formation was in the Guang'anNanchong-Suining-Yilong area,and the good exploration prospect of the Dongyuemiao Member was in the south of the Guang'an-Suining area. | Denghua Li Jianzhong Li Bin Zhang Jiajing Yang Shaoyong Wang | 2017 | Petroleum Research2017，2，4： | 2 |
| 19 | Melatonin antagonizes ovarian aging via YTHDF2-MAPK-NF-κB pathway显示文摘Cellular senescence is closely associated with age-related diseases.Ovarian aging,a special type of organ senescence,is the pathophysiological foundation of the diseases of the reproductive system.It is characterized by the loss of integrity of the surface epithelium and a gradual decrease in the number of human ovarian surface epithelial cells(HOSEpiCs).To contribute to the research on delaying ovarian aging,we aimed to investigate the novel epigenetic mechanism of melatonin in protecting HOSEpiCs.We discovered that melatonin has antagonistic effects against the oncogene-induced senescence(OIS)of HOSEpiCs.Mechanistically,the oncogene Ras decreased the expression of YTHDF2,which is the reader of RNA-m6A,by stimulating the generation of reactive oxygen species(ROS).Moreover,we found that the suppression of YTHDF2 increased the expression of MAP2K4 and MAP4K4 by enhancing the stability of the transcription of their mRNAs,thereby upregulating the expression of the senescence-associated secretory phenotype(SASP)through the activation of the MAP2K4 and MAP4K4-dependent nuclear factor-κB(NF-κB)signaling pathways.We further determined that melatonin has antagonistic effects against the OIS of HOSEpiCs by inhibiting the ROS-YTHDF2-MAPK-NF-κB pathway.These findings provide key insights into the potential avenues for preventing and treating ovarian aging. | Ruigong Zhu Xian Ji Xuan Wu Jiajing Chen Xuesong Li Hong Jiang Haiping Fu Hui Wang Zhe Lin Xin Tang Shixiu Sun Qingguo Li Bingjian Wang Hongshan Chen | 2022 | Genes & Diseases2022，9，2： | 2 |
| 20 | Detection of QTL and QTN and candidate genes for oil content in soybean using a combination of four-way-RIL and germplasm populations显示文摘Soybean is a source of edible oil for humans and provides a third of the vegetable oil consumed worldwide.Increasing seed oil content in seeds is thus a key objective in soybean breeding.In the present study,a four-way recombinant inbred line(FW-RIL)population comprising 144 lines,planted in 10 environments,and a germplasm panel of 455 accessions,planted in two environments,were used to collect oil-content phenotypes.First,59 quantitative trait loci(QTL)were detected in the FW-RIL population by inclusive complete interval mapping on a linkage map consisting of 2232 single-nucleotide polymorphism(SNP)markers.Also in the FW-RILs,44 quantitative trait nucleotides(QTNs)were detected by association analysis using 109,676 SNP markers and fivemethods of multi-locus genome-wide association study.Second,77 QTN were detected by association analysis in the germplasm panel using 63,306 markers.Comparison of the QTL and QTN suggested four QTN controlling oil content.Pathway analysis was performed on genes in attenuation regions of these four QTN,and two candidate genes involved in the synthesis or metabolism of soybean oil were identified.These findings provide useful information about the genetics of oil content and may contribute to its genetic improvement by marker-assisted selection. | Xiyu Li Kaixin Zhang Xu Sun Shanshan Huang Jiajing Wang Chang Yang Mahfishan Siyal Chao Wang Chunlan Guo Xiping Hu Wen-Xia Li Hailong Ning | 2020 | The Crop Journal2020，8，5： | 2 |
