| 1 | Feeding of Riptortus pedestris on soybean plants, the primary cause of soybean staygreen syndrome in the Huang-Huai-Hai river basin显示文摘Staygreen syndrome or Zhengqing in soybean has recently become a major issue for Chinese growers in the Huang-Huai-Hai river basin.Although previous studies revealed that staygreen can be induced when pods/seeds are damaged, it is unknown whether virus infection or insect infestation causes staygreen.To determine whether viral infection causes staygreen, a survey of soybean staygreen incidence in the Huang-Huai-Hai river basin was conducted in 2016 and 2017.Diseased samples were collected and analyzed using DAS-ELISA for Soybean mosaic virus, Watermelon mosaic virus, Bean pod mottle virus, Cucumber mosaic virus, and Bean common mosaic virus.The survey showed that the severity of soybean staygreen syndrome was most prevalent in Beijing, Henan, Shaanxi, and some parts of Shandong provinces, with yield losses from 0 to nearly 100%, but only a small fraction of samples were positive for the tested viruses.A field cage experiment and an insecticide treatment field trial were conducted to determine the contribution of the bean bug, Riptortus pedestris, to staygreen incidence.The field cage experiment showed that R.pedestris treatment resulted in shorter plants, more empty pods, increased numbers of abnormal seeds, and decreased yields.The field experiment showed that there were fewer R.pedestris and less soybean staygreen incidence in fields treated with insecticide than in untreated control fields.Together, these results suggest that R.pedestris infestation rather than virus infection induces staygreen syndrome and that growers in this region can mitigate staygreen syndrome via bean bug control. | Kai Li Xinxin Zhang Jianqiu Guo Hannah Penn Tingting Wu Lin Li Hong Jiang Lidan Chang Cunxiang Wu Tianfu Han | 2019 | The Crop Journal2019，7，3： | 30 |
| 2 | Hellebrigenin induces apoptosis in colorectal cancer Cells through induction of excessive reactive oxygen species显示文摘Traditional Chinese medicine(TCM)has been increasingly applied in both preventing and treating a variety of cancers in the last decades,attributing to its fewer side effects as compared with chemotherapy drugs.Hellebrigenin,a component of Chanpi from the skin of Bufo bufogargarizans Cantor or Duttaphrynus melanostictus has been reported to have an obvious anti-cancer activity on various cancers.However,the effect and mechanism of hellebrigenin on colorectal cancers were still unknown.Herein,the present study demonstrated hellebrigenin significantly reduced viability and triggered apoptosis via the intrinsic pathway in colorectal cancer cell lines HCT116 and HT29 in vitro and in vivo.Moreover,hellebrigenin led to a reduction of mitochondrial membrane potential.In addition,treatment with hellebrigenin could result in the induction of excessive reactive oxygen species,which led to cell apoptosis.These results indicated that hellebrigenin had anti-cancer potential in the treatment of colorectal cancers. | CHUNJIAO LIU QINHONG KONG FENG PAN SHAN JIANG LINGJIE MENG GAI HUANG LIDAN LU SANHUA LI YUN LIU | 2021 | BIOCELL2021，45，4： | 2 |
| 3 | Oxidized galectin-1 in SLE fails to bind the inhibitory receptor VSTM1 and increases reactive oxygen species levels in neutrophils显示文摘Inhibitory immune receptors set thresholds for immune cell activation,and their deficiency predisposes a person to autoimmune responses.However,the agonists of inhibitory immune receptors remain largely unknown,representing untapped sources of treatments for autoimmune diseases.Here,we show that V-set and transmembrane domain-containing 1(VSTM1)is an inhibitory receptor and that its binding by the competent ligand soluble galectin-1(Gal1)is essential for maintaining neutrophil viability mediated by downregulated reactive oxygen species production.However,in patients with systemic lupus erythematosus(SLE),circulating Gal1 is oxidized and cannot be recognized by VSTM1,leading to increased intracellular reactive oxygen species levels and reduced neutrophil viability.Dysregulated neutrophil function or death contributes significantly to the pathogenesis of SLE by providing danger molecules and autoantigens that drive the production of inflammatory cytokines and the activation of autoreactive lymphocytes.Interestingly,serum levels of glutathione,an antioxidant able to convert oxidized Gal1 to its reduced form,were negatively correlated with SLE disease activity.Taken together,our findings reveal failed inhibitory Gal1/VSTM1 pathway activation in patients with SLE and provide important insights for the development of effective targeted therapies. | Xu Jiang Xinyue Xiao Hao Li Yiyi Gong Min Wang Huaxia Yang Lidan Zhao Ying Jiang Yanping Wei Chongchong Zhao Jin Li Yuling Chen Shan Feng Haiteng Deng Shiliang Ma Yue Xu Yudong Liu George C.Tsokos Minghong Jiang Xuan Zhan | 2023 | Cellular & Molecular Immunology2023，20，11： | 1 |
| 4 | 组蛋白H3泛素化通过影响H3K9甲基化进而调控肝脏发育相关基因表达的机制显示文摘文章简介肝脏的发育是一个多步骤并且受到严格调控的过程。过去的研究主要集中在个体出生前肝细胞如何分裂分化,并且多以转录因子和信号通路为研究对象。相比之下,肝脏在个体出生后直至成熟的过程中,虽然肝脏的发育并未停止,但是研究资料相对匮乏。 | Gaofeng Li Tong Ji Jiang Chen Yufei Fu Lidan Hou Yan Feng Tingyue Zhang Tianyu Song Jie Zhao Yoko Endo Hui Lin 蔡秀军 仓勇 | 2018 | 科学新闻2018，0，4： | 0 |
| 5 | Proximity-enabled covalent binding of IL-2 to IL-2Rα selectively activates regulatory T cells and suppresses autoimmunity显示文摘Interleukin-2(IL-2)is a pleiotropic cytokine that orchestrates bidirectional immune responses via regulatory T cells(Tregs)and effector cells,leading to paradoxical consequences.Here,we report a strategy that exploited genetic code expansion-guided incorporation of the latent bioreactive artificial amino acid fluorosulfate-L-tyrosine(FSY)into IL-2 for proximity-enabled covalent binding to IL-2Rαto selectively promote Treg activation.We found that FSY-bearing IL-2 variants,such as L72-FSY,covalently bound to IL-2Rαvia sulfur-fluoride exchange when in proximity,resulting in persistent recycling of IL-2 and selectively promoting the expansion of Tregs but not effector cells.Further assessment of L72-FSY-expanded Tregs demonstrated that L72-FSY maintained Tregs in a central memory phenotype without driving terminal differentiation,as demonstrated by simultaneously attenuated expression of lymphocyte activation gene-3(LAG-3)and enhanced expression of programmed cell death protein-1(PD-1).Subcutaneous administration of L72-FSY in murine models of pristane-induced lupus and graft-versus-host disease(GvHD)resulted in enhanced and sustained therapeutic efficacy compared with wild-type IL-2 treatment.The efficacy of L72-FSY was further improved by N-terminal PEGylation,which increased its circulatory retention for preferential and sustained effects.This proximity-enabled covalent binding strategy may accelerate the development of pleiotropic cytokines as a new class of immunomodulatory therapies. | Bo Zhang Jiaqi Sun Yeshuang Yuan Dezhong Ji Yeting Sun Yudong Liu Shengjie Li Xingxing Zhu Xunyao Wu Jin Hu Qiu Xie Ling Wu Lulu Liu Boyang Cheng Yuanjie Zhang Lingjuan Jiang Lidan Zhao Fei Yu Wei Song Min Wang Yue Xu Shiliang Ma Yunyun Fei Lihe Zhang Demin Zhou Xuan Zhang | 2023 | Signal Transduction and Targeted Therapy2023，8，2： | 0 |
| 6 | Ultra-high spectral purity laser derived from weak external distributed perturbation显示文摘Ultra-high spectral purity lasers are of considerable research interests in numerous fields such as coherent optical communication,microwave photonics,distributed optical fiber sensing,gravitational wave detection,optical clock,and so on.Herein,to deeply purify laser spectrum with compact size under normal condition,we propose a novel and practical idea to effectively suppress the spontaneous radiation of the laser cavity through weak external distributed perturbation.Subsequently,a laser configuration consisting of a main lasing cavity and an external distributed feedback cavity is proposed.The feedback signal with continuous spatio-temporal phase transition controlled by a distributed feedback structure is injected into the main cavity,which can deeply suppress the coupling rate from the spontaneous radiation to the stimulated emission and extremely purify the laser spectrum.Eventually,an ultra-narrow linewidth on-chip laser system with a side mode suppression ratio greater than 80 dB,an output linewidth of 10 Hz,and a relative intensity noise less than-150 dB/Hz is successfully obtained under normal conditions.The proposed concept in this work provides a new perspective for extreme regulation of laser parameters by using weak external distributed perturbation,which can be valid for various gain-type lasers with wide wavelength bands. | Laiyang Dang Ligang Huang Leilei Shi Fuhui Li Guolu Yin Lei Gao Tianyi Lan Yujia Li Lidan Jiang Tao Zhu | 2023 | Opto-Electronic Advances2023，6，2： | 0 |
| 7 | Mapping the genetic architecture of developmental modularity in ornamental plants显示文摘Developmental modularity,i.e.,coherent organization and function of developmentally related traits,is an emergent property of organismic development and evolution.However,knowledge about how modular variation and evolution are driven genetically is still limited.Here,using ornamental plants as an example,we propose a computational framework to map,visualize and annotate the genetic architecture of trait modularity by integrating modularity theory into system mapping,a statistical model for multifaceted genetic mapping of complex traits.A developmental module can be viewed as an ecosystem,in which the constituting components compete for space and resources or cooperate symbiotically to organize its function and behavior.This interactive process is quantified by mathematical models and evolutionarily interpreted by game theory.The proposed framework can test whether and how genes regulate the coordination of different but interconnected traits through their competition or cooperation to downstream developmental modularity. | Zhenying Wen Libo Jiang Mingyu Li Ang Dong Meixia Ye Juan Meng Ping Li Tangren Cheng Qixiang Zhang Lidan Sun | 2021 | Ornamental Plant Research2021，1，1： | 0 |
