| 1 | Xenopus GLP-1-based glycopeptides as dual glucagon-like peptide 1 receptor/glucagon receptor agonists with improved in vivo stability for treating diabetes and obesity显示文摘Peptide dual agonists toward both glucagon-like peptide 1 receptor(GLP-1R)and glucagon receptor(GCGR)are emerging as novel therapeutics for the treatment of type 2 diabetes mellitus(T2DM)patients with obesity.Our previous work identified a Xenopus GLP-1-based dual GLP-1R/GCGR agonist termed xGLP/GCG-13,which showed decent hypoglycemic and body weight lowering activity.However,the clinical utility of xGLP/GCG-13 is limited due to its short in vivo half-life.Inspired by the fact that O-GlcNAcylation of intracellular proteins leads to increased stability of secreted proteins,we rationally designed a panel of O-GlcNAcylated xGLP/GCG-13 analogs as potential long-acting GLP-1R/GCGR dual agonists.One of the synthesized glycopeptides 1f was found to be equipotent to xGLP/GCG-13 in cell-based receptor activation assays.As expected,O-GlcNAcylation effectively improved the stability of xGLP/GCG-13 in vivo.Importantly,chronic administration of 1f potently induced body weight loss and hypoglycemic effects,improved glucose tolerance,and normalized lipid metabolism and adiposity in both db/db and diet induced obesity(DIO)mice models.These results supported the hypothesis that glycosylation is a useful strategy for improving the in vivo stability of GLP-1-based peptides and promoted the development of dual GLP-1R/GCGR agonists as antidiabetic/antiobesity drugs. | LI Qiang YANG Qimeng HAN Jing LIU Xiaohan FU Junjie YIN Jian | 2022 | Chinese Journal of Natural Medicines2022,20,11: | 1 |
| 2 | Anisotropic MOF-on-MOF Growth of Isostructural Multilayer Metal–Organic Framework Heterostructures显示文摘Isostructural MOFs with similar crystallographic parameter are easily available for MOF-on-MOF growth and possible to form core–shell structure by isotropic growth.However,due to well-matched cell lattice,selective growth in isostructural MOF heterostructures remains a great challenge for engineering atypical MOF heterostructures.Herein,an anisotropic MOF-onMOF growth strategy was developed to structure a range of multilayer sandwich-like ZIF-L heterostructures via stacking isostructural ZIF-L-Zn and ZIF-L-Co alternately with three-,five-,seven-,and more layer structures.Moreover,these heterostructures with highly designable feature were fantastic precursors for fabricating derivatives with tunable magnetic and catalytic properties.Such strategy explores a novel way of achieving anisotropic MOF-on-MOF growth between isostructural MOFs and opens up new horizons for regulating the properties by MOF modular assembly in versatile functional nanocomposites. | Zhida Gu Wenlei Zhang Ting Pan Yu Shen Peishan Qin Peng Zhang Xiaohan Li Liwei Liu Linjie Li Yu Fu Weina Zhang Fengwei Huo | 2021 | Research2021,,1: | 1 |
| 3 | Differences of tuffaceous components dissolution and their impact on physical properties in sandstone reservoirs: A case study on Paleogene Wenchang Formation in Huizhou-Lufeng area, Zhu I Depression, Pearl River Mouth Basin, China显示文摘The element geochemical characteristics and diagenetic alteration products of tuffaceous components in sandstone reservoirs of Paleogene Wenchang Formation in typical subsags of the Huizhou-Lufeng area of the Zhu I Depression,Pearl River Mouth Basin,were identified through microscopic analysis and quantitative analysis of main and trace elements.The impacts of dissolution of different tuffaceous components on physical properties of reservoirs were discussed through quantitative characterization of reservoir physical properties.The results show that there are mainly four types of tuffaceous components in the study area,which are acidic,intermediate,basic and alkaline tuffaceous components.The acidic tuffaceous components evolved in a process of strong alteration and weak dissolution of alteration products,with a large amount of kaolinite precipitated during alteration to disenable the improvement of porosity and permeability.The intermediate and alkaline tuffaceous components evolved in a process of strong dissolution of tuffaceous components and strong alteration of residual tuffaceous components;the dissolution of tuffaceous components created intergranular pores,but the alteration products such as autogenic quartz,apatite and illite deteriorated the pore structure;ultimately,the dissolution of tuffaceous components resulted in the increase of porosity but no increase of permeability of the reservoir.The basic tuffaceous components dominantly evolved in a process of dissolution of tuffaceous components to strong dissolution of alteration products;both tuffaceous components between particles and laumontite generated from alteration can be strongly dissolved to create pores;thus,the dissolution of tuffaceous components can significantly increase the physical properties of the reservoir. | JIN Zihao YUAN Guanghui ZHANG Xiangtao CAO Yingchang DING Lin LI Xiaoyan FU Xiaohan | 2023 | Petroleum Exploration and Development2023,50,1: | 0 |
| 4 | Effect of seasonal snow on the start of growing season of typical vegetation in Northern Hemisphere显示文摘Under global warming, seasonal snow takes faster melting rate than before, which greatly changes the hydro-logical cycle. In this study, by targeting three typical seasonal snow-covered land types (i.e., open shrubland,evergreen needleleaf forest and mixed forest) in the Northern Hemisphere, the start of growing season (SGS) hasbeen found obviously advanced in the past years, greatly contributed by the faster melting rate of seasonal snow.It is manifested that significantly positive correlation has been found between SGS and May snow depth for openshrubs, March and April snow depth for evergreen needleleaf forests and March snow depth for mixed forests.However, such close association is not appeared in all the climate conditions of same vegetation. In the future,as the rate of melting snow becomes faster in the high emission of greenhouse gasses than the current situation,continuously advanced SGS will accelerate the change of vegetation distribution in the Northern Hemisphere.These findings offer insights into understanding the effect from seasonal snow on vegetation and promote thesustainable utilization of regional vegetation in the Northern Hemisphere. | Xiaodan Guan Shuyang Guo Jianping Huang Xiaohan Shen Li Fu Guolong Zhang | 2022 | Geography and Sustainability2022,3,3: | 0 |
| 5 | Geographical distribution of Aspergillus flavus in peanut harvest period in China显示文摘In order to grasp the distribution of Aspergillus flavus in the soil of peanut production areas in China,A.flavus biomarkers were tested on 555 soil samples from 37 sampling points in 17 provinces,peanut fields in four agroecological zones(Southern area,Yangtze River Basin,Northern area,Northeast area).The results showed that(1)the cultivation amount of A.flavus per gram of soil in the Yangtze River Basin is 1.30 times that of the southern area,1.56 times that of the northern area,and 6.20 times that of the northeast area,with obvious regional characteristics.(2)In the Yangtze River basin,the change of longitude in the east-west direction has no direct impact on the cultivation amount of A.flavus per gram of soil.(3)In the east coast,the A.flavus cultivated per gram of soil increased first and then decreased with the increase of latitude from south to north.(4)A.flavus can be isolated in the soil samples above 1000 m.Field pollution is an important source of aflatoxin contamination in peanut.The study on the distribution of A.flavus in soil in China could provide theoretical support for the early warning and prevention and control measures of aflatoxin contamination in peanut. | Xiaohan Liu Jiayun Fu Mingbo Wen Haohua Gu Pingping Ji Xiaofeng Yue Xiaoqian Tang Meijuan Liang Yang Zhou Qi Zhang Peiwu Li | 2023 | Oil Crop Science2023,8,2: | 0 |
| 6 | Living Electrospun Short Fibrous Sponge via Engineered Nanofat for Wound Healing显示文摘Living cells and active factors are the two core elements of tissue repair,directly affecting the healing efficiency of damaged tissue.Nanofat(NF)can release living cells,such as adipose-derived stem cells(ADSCs),as well as active growth factors to promote angiogenesis,thus realizing cell-based wound healing.Herein,a novel living electrospun short fibrous sponge is constructed by modifying three-dimensional(3D)bionic short fibers with engineered NF.The uniform distribution of the polydopamine(PDA)modification endows the living sponges with stable mechanical properties,reversible water absorption and excellent adhesion even after repeated compression by an external force and long-term aqueous immersion.Meanwhile,the living electrospun short fibrous sponges with uniform NF modification contain living cells such as ADSCs and active growth factors such as vascular endothelial growth factor(VEGF),which can effectively promote the tube formation of human umbilical vein endothelial cells(HUVECs).In vivo,the living sponges can effectively and continuously act on wounds and act as a bionic living skin to prevent the loss of internal nutrients,creating a comfortable and favorable microenvironment for tissue regeneration and promoting the healing of diabetic wounds.Therefore,living electrospun short fibrous sponges via engineered NF are expected to achieve continuous wound healing with in situ living cells and active factors in injured tissues. | Xiaohan Fu Juan Wang Dejian Qian Zhaowen Chen Liang Chen Wenguo Cui Yan Wang | 2023 | Advanced Fiber Materials2023,5,3: | 0 |

| 9 | Al-induced CsUGT84J2 enhances flavonol and auxin accumulation to promote root growth in tea plants显示文摘Although Al is not necessary or even toxic to most plants,it is beneficial for the growth of tea plants.However,the mechanism through which Al promotes root growth in tea plants remains unclear.In the present study,we found that flavonol glycoside levels in tea roots increased following Al treatment,and the Al-induced UDP glycosyltransferase CsUGT84J2 was involved in this mechanism.Enzyme activity assays revealed that rCsUGT84J2 exhibited catalytic activity on multiple types of substrates,including phenolic acids,flavonols,and auxins in vitro.Furthermore,metabolic analysis with UPLC-QqQ-MS/MS revealed significantly increased flavonol and auxin glycoside accumulation in CsUGT84J2-overexpressing Arabidopsis thaliana.In addition,the expression of genes involved in the flavonol pathway as well as in the auxin metabolism,transport,and signaling pathways was remarkably enhanced.Additionally,lateral root growth and exogenous Al stress tolerance were significantly improved in transgenic A.thaliana.Moreover,gene expression and metabolic accumulation related to phenolic acids,flavonols,and auxin were upregulated in CsUGT84J2-overexpressing tea plants but downregulated in CsUGT84J2-silenced tea plants.In conclusion,Al treatment induced CsUGT84J2 expression,mediated flavonol and auxin glycosylation,and regulated endogenous auxin homeostasis in tea roots,thereby promoting the growth of tea plants.Our findings lay the foundation for studying the precise mechanisms through which Al promotes the growth of tea plants. | Xiaolan Jiang Sanyan Lai Dexu Kong Xiaohan Hou Yufeng Shi Zhouping Fu Yajun Liu Liping Gao Tao Xia | 2023 | Horticulture Research2023,10,6: | 0 |
