| 1 | Supermolecular layered double hydroxides显示文摘Research progresses in the layered double hydroxides [M2+(1-x)M3+x(OH)2]x+An-x/n.mH2O intercalatedwith metal coordinate ions or oxometalates in the last ten years are reviewed. These layered double hydroxides are mainly intercalated with polyoxometalate (POM) ions, a LiAl-LDH photochemical assembly containing TiO2 and CH3(CH2)12COO- anions, together with Zn(TPPC) (porphy-rin derivate) and macrocyclic ligand-containing porphyrin derivate anions. Emphasis is put on the synthesis methods for intercalation of the anions into the interlayer regions, the characterization techniques and structures for the layeredcompounds and the newest research progress in the fields such as catalysis. The review also forecasts the prospects of the field. | Hu Changwen Li Danfeng Guo Yihang Wang Enbo | 2001 | Chinese Science Bulletin2001，46，13： | 3 |
| 2 | A novel integrated non-targeted metabolomic analysis reveals significant metabolite variations between different lettuce (Lactuca sativa. L) varieties显示文摘Lettuce is an important leafy vegetable that represents a significant dietary source of antioxidants and bioactive compounds.However,the levels of metabolites in different lettuce cultivars are poorly characterized.In this study,we used combined GC×GC-TOF/MS and UPLC-IMS-QTOF/MS to detect and relatively quantify metabolites in 30 lettuce cultivars representing large genetic diversity.Comparison with online databases,the published literature,standards as well using collision cross-section values enabled putative identification of 171 metabolites.Sixteen of these 171 metabolites(including phenolic acid derivatives,glycosylated flavonoids,and one iridoid)were present at significantly different levels in leaf and head type lettuces,which suggested the significant metabolomic variations between the leaf and head types of lettuce are related to secondary metabolism.A combination of the results and metabolic network analysis techniques suggested that leaf and head type lettuces contain not only different levels of metabolites but also have significant variations in the corresponding associated metabolic networks.The novel lettuce metabolite library and novel non-targeted metabolomics strategy devised in this study could be used to further characterize metabolic variations between lettuce cultivars or other plants.Moreover,the findings of this study provide important insight into metabolic adaptations due to natural and human selection,which could stimulate further research to potentially improve lettuce quality,yield,and nutritional value. | Xiao Yang Shiwei Wei Bin Liu Doudou Guo Bangxiao Zheng Lei Feng Yumin Liu Francisco A.Tomás-Barberán Lijun Luo Danfeng Huang | 2018 | Horticulture Research2018，5，1： | 3 |

| 6 | Tumor extracellular vesicles mediate anti-PD-L1 therapyresistance by decoying anti-PD-L1显示文摘PD-L1+tumor-derived extracellular vesicles(TEVs)cause systemic immunosuppression and possibly resistance to anti-PD-L1 antibody(αPD-L1)blockade.However,whether and how PD-L1+TEVs mediateαPD-L1 therapy resistance is unknown.Here,we show that PD-L1+TEVs substantially decoyαPD-L1 and that TEV-boundαPD-L1 is more rapidly cleared by macrophages,causing insufficient blockade of tumor PD-L1 and subsequentαPD-L1 therapy resistance.Inhibition of endogenous production of TEVs by Rab27a or Coro1a knockout reversesαPD-L1 therapy resistance.Either an increasedαPD-L1 dose or macrophage depletion mediated by the clinical drug pexidartinib abolishesαPD-L1 therapy resistance.Moreover,in the treatment cycle with the same total treatment dose ofαPD-L1,high-dose and low-frequency treatment had better antitumor effects than low-dose and highfrequency treatment,induced stronger antitumor immune memory,and eliminatedαPD-L1 therapy resistance.Notably,in humanized immune system mice with human xenograft tumors,both increasedαPD-L1 dose and high-dose and low-frequency treatment enhanced the antitumor effects ofαPD-L1.Furthermore,increased doses ofαPD-L1 andαPD-1 had comparable antitumor effects,butαPD-L1 amplified fewer PD-1+Treg cells,which are responsible for tumor hyperprogression.Altogether,our results reveal a TEV-mediated mechanism ofαPD-L1-specific therapy resistance,thus providing promising strategies to improveαPD-L1 efficacy. | Jiming Chen Jie Yang Wenhui Wang Danfeng Guo Chengyan Zhang Shibo Wang Xinliang Lu Xiaofang Huang Pingli Wang Gensheng Zhang Jing Zhang Jianli Wang Zhijian Cai | 2022 | Cellular & Molecular Immunology2022，19，11： | 1 |

| 19 | Filamentation initiated by Cas2 and its association with the acquisition process in cells显示文摘Cas1-and-Cas2-mediated new spacer acquisition is an essential process for bacterial adaptive immunity.The process is critical for the ecology of the oral microflora and oral health.Although molecular mechanisms for spacer acquisition are known,it has never been established if this process is associated with the morphological changes of bacteria.In this study,we demonstrated a novel Cas2-induced filamentation phenotype in E.coli that was regulated by co-expression of the Cas1 protein.A 30 amino acid motif at the carboxyl terminus of Cas2 is necessary for this function.By imaging analysis,we provided evidence to argue that Cas-induced filamentation is a step coupled with new spacer acquisition during which filaments are characterised by polyploidy with asymmetric cell division.This work may open new opportunities to investigate the adaptive immune response and microbial balance for oral health. | Lei Wang Xin Yu Mengjie Li Guiqin Sun Lin Zou Tiansheng Li Linlin Hou Yameng Guo Danfeng Shen Di Qu Xunjia Cheng Li Chen | 2019 | International Journal of Oral Science2019，11，4： | 0 |
| 20 | DNA Fingerprinting of Ninety Wild Strains of Agaricus from China显示文摘Ninety wild strains of Agaricus collected in China,including 44 strains preliminarily identified as Agaricus bisporus by isozyme electrophoresis,were studied using SRAP and ISSR techniques.Eighteen specific SRAP bands and 12 specific ISSR bands were scored,and a cluster dendrogram was constructed.The 90 wild strains of Agaricus were separated into two major groups,the first consisting of wild strains of A.bisporus and the second consisting of other Agaricus strains.Forty-one wild strains of A.bisporus collected in Sichuan and Tibet formed four groups according to the geographical location of the collection area.White A.bisporus strains from Xinjiang and Tibet(Xinjiang Wild,AgX04 and AgX042)exhibited unique band patterns resulting in lower similarity coefficient values(10%~13%)when compared with brown or light-brown A.bisporus strains. | CHEN Meiyuan LIAO Jianhua WANG Bo LI Hongrong LU Zhenghui GUO Zhongjie CAI Danfeng WANG Zesheng | 2009 | 食用菌学报2009，16，1： | 0 |
