1Oncogenic AURKA-enhanced N6-methyladenosine modification increases DROSHA mRNA stability to transactivate STC1 in breast cancer stem-like cells显示文摘RNase III DROSHA is upregulated in multiple cancers and contributes to tumor progression by hitherto unclear mechanisms.Here,we demonstrate that DROSHA interacts withβ-Catenin to transactivate STC1 in an RNA cleavage-independent manner,contributing to breast cancer stem-like cell(BCSC)properties.DROSHA mRNA stability is enhanced by N6-methyladenosine(m^(6)A)modification which is activated by AURKA in BCSCs.AURKA stabilizes METTL14 by inhibiting its ubiquitylation and degradation to promote DROSHA mRNA methylation.Moreover,binding of AURKA to DROSHA transcript further strengthens the binding of the m^(6)A reader IGF2BP2 to stabilize m^(6)A-modified DROSHA.In addition,wild-type DROSHA,but not an m^(6)A methylation-deficient mutant,enhances BCSC stemness maintenance,while inhibition of DROSHA m^(6)A modification attenuates BCSC traits.Our study unveils the AURKA-induced oncogenic m^(6)A modification as a key regulator of DROSHA in breast cancer and identifies a novel DROSHA transcriptional function in promoting the BCSC phenotype.Fei Peng Jie Xu Bai Cui Qilan Liang Sai Zeng Bin He Hong Zou Manman Li Huan Zhao Yuting Meng Jin Chen Bing Liu Shasha Lv Peng Chu Fan An Zifeng Wang Junxiu Huang Yajing Zhan Yuwei Liao Jinxin Lu Lingzhi Xu Jin Zhang Zhaolin Su Zhiguang Li Fangjun Wang Eric W-FLam Quentin Liu 2021Cell Research2021,31,3:9
2Guiding T lymphopoiesis from pluripotent stem cells by defined transcription factors显示文摘Achievement of immunocompetent and therapeutic T lymphopoiesis from pluripotent stem cells(PSCs)is a central aim in T cell regenerative medicine.To date,preferentially reconstituting T lymphopoiesis in vivo from PSCs remains a practical challenge.Here we documented that synergistic and transient expression of Runx1 and Hoxa9 restricted in the time window of endothelial-to-hematopoietic transition and hematopoietic maturation stages in a PSC differentiation scheme(iR9-PSC)in vitro induced preferential generation of engraftable hematopoietic progenitors capable of homing to thymus and developing into mature T cells in primary and secondary immunodeficient recipients.Single-cell transcriptome and functional analyses illustrated the cellular trajectory of T lineage induction from PSCs,unveiling the T-lineage specification determined at as early as hemogenic endothelial cell stage and identifying the bona fide pre-thymic progenitors.The induced T cells distributed normally in central and peripheral lymphoid organs and exhibited abundant TCRαβrepertoire.The regenerative T lymphopoiesis restored immune surveillance in immunodeficient mice.Furthermore,gene-edited iR9-PSCs produced tumor-specific T cells in vivo that effectively eradicated tumor cells.This study provides insight into universal generation of functional and therapeutic T cells from the unlimited and editable PSC source.Rongqun Guo Fangxiao Hu Qitong Weng Cui Lv Hongling Wu Lijuan Liu Zongcheng Li Yang Zeng Zhijie Bai Mengyun Zhang Yuting Liu Xiaofei Liu Chengxiang Xia Tongjie Wang Peiqing Zhou Kaitao Wang Yong Dong Yuxuan Luo Xiangzhong Zhang Yuxian Guan Yang Geng Juan Du Yangqiu Li Yu Lan Jiekai Chen Bing Liu Jinyong Wang 2020Cell Research2020,30,1:7
3No expenditure difference among patients with liver cancer at stageⅠ-ⅣV:Findings from a multicenter cross-sectional study in China显示文摘Objective:The number of liver cancer patients in China accounts for more than half of the world.However,China currently lacks national,multicenter economic burden data,and meanwhile,measuring the differences among different subgroups will be informative to formulate corresponding policies in liver cancer control.Thus,the aim of the study was to measure the economic burden of liver cancer by various subgroups.Methods:A hospital-based,multicenter and cross-sectional survey was conducted during 2012・2014,covering 39 hospitals and 21 project sites in 13 provinces across China.The questionnaire covers clinical information,sociology,expenditure,and related variables.All expenditure data were reported in Chinese Yuan(CNY)using 2014 values.Results:A total of 2,223 liver cancer patients were enrolled,of whom 59.61%were late-stage cases(III-IV),and 53.8%were hepatocellular carcinoma.The average total expenditure per liver cancer patient was estimated as 53,220 CNY,including 48,612 CNY of medical expenditures(91.3%)and 4,608 CNY of non-medical expenditures(8.7%).The average total expenditures in stage I,H,m and stage IV were 52,817 CNY,50,877 CNY,50,678 CNY and 54,089 CNY(P>0.05),respectively.Non-medical expenditures including additional meals,additional nutrition care,transportation,accommodation and hired informal nursing were 1,453 CNY,839 CNY,946 CNY,679 CNY and 200 CNY,respectively.The one-year out-of-pocket expenditure of a newly diagnosed patient was 24,953 CNY,and 77.2%of the patients suffered an unmanageable financial burden.Multivariate analysis showed that overall expenditure differed in almost all subgroups(P<0.05),except for sex,clinical stage,and pathologic type.Conclusions:There was no difference in treatment expenditure for liver cancer patients at different clinical stages,which suggests that maintaining efforts on treatment efficacy improvement is important but not enough.To fiirtherly reduce the overall economic burden from liver cancer,more effort should be given to primary and secondary prevention strategies.Haike Lei Lin Lei Jufang Shi Yongzhong Wu Ling Liang Huiyao Huang Mei He Fangzhou Bai Maomao Cao Hui Qiu Yuting Wang Chengcheng Liu Jia Du Hong Wang Yan Zhang Mengdi Cao Ji Peng Ni Li Chunfeng Qu Min Dai Wanqing Chen Jie He 2020Chinese Journal of Cancer Research2020,32,4:7
4Model updating for real time dynamic substructures based on UKF algorithm显示文摘Combining the advantages of numerical simulation with experimental testing,real-time dynamic substructure(RTDS)testing provides a new experimental method for the investigation of engineered structures.However,not all unmodeled parts can be physically tested,as testing is often limited by the capacity of the test facility.Model updating is a good option to improve the modeling accuracy for numerical substructures in RTDS.In this study,a model updating method is introduced,which has great performance in describing this nonlinearity.In order to determine the optimal parameters in this model,an Unscented Kalman Filter(UKF)-based algorithm was applied to extract the knowledge contained in the sensors data.All the parameters that need to be identified are listed as the extended state variables,and the identification was achieved via the step-by-step state prediction and state update process.Effectiveness of the proposed method was verified through a group of experimental data,and results showed good agreement.Furthermore,the proposed method was compared with the Extended Kalman Filter(EKF)-based method,and better accuracy was easily found.The proposed parameter identification method has great applicability for structural objects with nonlinear behaviors and could be extended to research in other engineering fields.Su Tingli Tang Zhenyun Peng Lingyun Bai Yuting Jin Xuebo Kong Jianlei 2020Earthquake Engineering and Engineering Vibration2020,19,2:2
5Transcription factor-based gene therapy to treat glioblastoma through direct neuronal conversion显示文摘Objective:Glioblastoma(GBM)is the most prevalent and aggressive adult primary cancer in the central nervous system.Therapeutic approaches for GBM treatment are under intense investigation,including the use of emerging immunotherapies.Here,we propose an alternative approach to treat GBM through reprogramming proliferative GBM cells into non-proliferative neurons.Methods:Retroviruses were used to target highly proliferative human GBM cells through overexpression of neural transcription factors.Immunostaining,electrophysiological recording,and bulk RNA-seq were performed to investigate the mechanisms underlying the neuronal conversion of human GBM cells.An in vivo intracranial xenograft mouse model was used to examine the neuronal conversion of human GBM cells.Results:We report efficient neuronal conversion from human GBM cells by overexpressing single neural transcription factor Neurogenic differentiation 1(Neuro D1),Neurogenin-2(Neurog2),or Achaete-scute homolog 1(Ascl1).Subtype characterization showed that the majority of Neurog2-and Neuro D1-converted neurons were glutamatergic,while Ascl1 favored GABAergic neuron generation.The GBM cell-converted neurons not only showed pan-neuronal markers but also exhibited neuron-specific electrophysiological activities.Transcriptome analyses revealed that neuronal genes were activated in glioma cells after overexpression of neural transcription factors,and different signaling pathways were activated by different neural transcription factors.Importantly,the neuronal conversion of GBM cells was accompanied by significant inhibition of GBM cell proliferation in both in vitro and in vivo models.Conclusions:These results suggest that GBM cells can be reprogrammed into different subtypes of neurons,leading to a potential alternative approach to treat brain tumors using in vivo cell conversion technology.Xin Wang Zifei Pei Aasma Hossain Yuting Bai Gong Chen 2021Cancer Biology & Medicine2021,18,3:2
6In situ synthesis of biomass-derived Ni/C catalyst by self-reduction for the hydrogenation of levulinic acid to γ-valerolactone显示文摘Herein,we reported in situ synthesis of biomass-derived Ni/C catalyst by self-reduction with pomelo peel.Compared with the conventional method, which includes carbonization, activation, impregnation and reduction, the entire preparation process was simplified to two steps, which was more straightforward. This synthesis method was green as Ni/C can be prepared without any additional chemical and the self-reduction process was realized in N2, which can avoid using H2 thus averting some problems such as storage, transportation and safety of H2. Meanwhile, the size and dispersion of Ni particles can be controlled by changing carbonization temperature.The synthesis mechanism of Ni/C catalyst with selfreduction was investigated, which was mainly attributed to the carbon and reducing gas produced during the carbonization process.For the catalytic performance of GVL synthesis, a high yield (94.5%) can be obtained and it exhibited good stability up to 5 cycles without obvious loss of catalytic activity.Shuqi Fang Zhibing Cui Yuting Zhu Chenguang Wang Jing Bai Xinghua Zhang Ying Xu Qiying Liu Lungang Chen Qi Zhang Longlong Ma 2019Journal of Energy Chemistry2019,28,10:1

8High-performance bulk thermoelectric materials and devices显示文摘Thermoelectric technology has intrigued wide-spread interests with a direct conversion between electricity and heat.The study on thermoelectric materials ultimately comes down to improving electrical properties and reducing lattice thermal conductivity,thus leading to a considerable thermoelectric figure of merit(zT).In this paper,we summarize our recent progress in skutterudites,diamond-like compounds,liquid-like materials,thermoelectric critical phenomena and mosaic crystals,and thermoelectric devices.The significant improvement in thermoelectric materials and devices greatly promotes thermoelectric technology as an important role in future energy solution.QIN YuTing ZHANG QiHao QIU PengFei BAI ShengQiang SHI Xun CHEN LiDong 2016Science Foundation in China2016,24,4:1
9Alkaline activation of endogenous latent TGFβ1 by an injectable hydrogel directs cell homing for in situ complex tissue regeneration显示文摘Utilization of the body’s regenerative potential for tissue repair is known as in situ tissue regeneration.However,the use of exogenous growth factors requires delicate control of the dose and delivery strategies and may be accompanied by safety,efficacy and cost concerns.In this study,we developed,for the first time,a biomaterial-based strategy to activate endogenous transforming growth factor beta 1(TGFβ1)under alkaline conditions for effective in situ tissue regeneration.We demonstrated that alkaline-activated TGFβ1 from blood serum,bone marrow fluids and soaking solutions of meniscus and tooth dentin was capable of increasing cell recruitment and early differentiation,implying its broad practicability.Furthermore,we engineered an injectable hydrogel(MS-Gel)consisting of gelatin microspheres for loading strong alkaline substances and a modified gelatin matrix for hydrogel click crosslinking.In vitro models showed that alkaline MS-Gel controllably and sustainably activated endogenous TGFβ1 from tooth dentin for robust bone marrow stem cell migration.More importantly,infusion of in vivo porcine prepared root canals with alkaline MS-Gel promoted significant pulp-dentin regeneration with neurovascular stroma and mineralized tissue by endogenous proliferative cells.Therefore,this work offers a new bench-to-beside translation strategy using biomaterial-activated endogenous biomolecules to achieve in situ tissue regeneration without the need for cell or protein delivery.Sainan Wang Yuting Niu Peipei Jia Zheting Liao Weimin Guo Rodrigo Cotrim Chaves Khanh-Hoa Tran-Ba Ling He Hanying Bai Sam Sia Laura J.Kaufman Xiaoyan Wang Yongsheng Zhou Yanmei Dong Jeremy J.Mao 2022Bioactive Materials2022,7,9:1
10A deep network prediction model for heavy metal cadmium in the rice supply chain显示文摘Cadmium and its compounds are currently known as Class I carcinogens,and excessive intake can cause severe health damage to humans.Rice has a strong absorption effect on cadmium,and rice products with excessive cadmium content have caused several significant public health contamination incidents.It is essential to predict the development trend of cadmium hazards in the rice supply chain so that countermeasures can be formulated to reduce the hazards.This paper proposes a deep prediction model for cadmium hazards in the rice supply chain based on the regularization method.Firstly,a long and short-term memory network is used to build the depth prediction model by using the regularization method,and the noise penalty term is added to reduce the model fitting to the noise and prevent the over-fitting caused by the noise.Finally,the optimization of the model hyperparameters was carried out using a Bayesian optimization approach to develop the prediction performance.Then,early warning system for prediction of cadmium hazards in the rice supply chain is built based on the deep prediction model proposed in this paper with SOA architecture,including data resource,business logic,and application service layers.The proposed model performs well on an actual data set of cadmium hazards in the rice supply chain and fits the data well.Xuebo Jin Jiashuai Zhang Xiaoyi Wang Xin Zhang Tianyang Guo Ce Shi Tingli Su Jianlei Kong Yuting Bai 2021Journal of Future Foods2021,1,2:0
11Formation mechanisms of reactive carbonyl species from fatty acids in dry-cured fi sh during storage in the presence of free radicals显示文摘This study aimed to better understand the changes of fatty acids in dry-cured fish during storage,and to analyze the reactive carbonyl species(RCS)formation mechanism primarily from the standpoint of oxygen-derived free radical reactions interactions.Oleic acid and linoleic acid were the predominant unsaturated fatty acids in dry-cured fish.The content of unsaturated fatty acids in dry-cured fish increased over time at 4℃,while decreased at 25℃.Singlet oxygen,superoxide anion and hydroxyl-alkyl radical levels increased with time,and more free radicals were yielded in the samples held at 25℃.Redundancy analysis revealed that hydroxyl-alkyl radicals had the greatest influence on the oxidation of lipids.Hydroxyl-alkyl radicals and singlet oxygen levels were positively correlated with 4-hydroxy-2-nonenal(HNE),malondialdehyde(MDA),peroxide value and acid value levels,but adversely to 4-hydroxy-2-hexenal(HHE)and fatty acids levels.Moreover,HNE and MDA were both inversely linked with fatty acids contents.It is possible that the intermediates of lipid oxidation undergo oxidation,cleavage and other reactions due to free radical activity,resulting in the generation of aldehyde precursors.These findings help us further characterize the lipid oxidation and RCS formation mechanism in dry-cured fish during storage.Qi Zhang Shiliang Jia Yan Bai Xuxia Zhou Yuting Ding 2021Journal of Future Foods2021,1,2:0
12Mild and efficient recovery of lithium-ion battery cathode material by deep eutectic solvents with natural and cheap components显示文摘Dissolution of lithium cobalt oxide(LCO)is the key step for the recovery of valuable metals(e.g.,Co and Li)from spent LCO-based lithium-ion batteries(LIBs).However,the dissolution process of LCO either needs toxic solvents,and high temperature,or shows low efficiency.Deep eutectic solvents(DESs)are potential green solvents to dissolve LCO.Here,DESs with polyethylene glycol(PEG)as hydrogen bond acceptor and ascorbic acid(AA)as hydrogen bond donor are found to dissolve LCO with 84.2%Co leaching efficiency at 80℃ and 72 h,which is higher than that from the reported references by common DESs.Furthermore,both DESs components(i.e.,PEG and AA)are cheap,biodegradable,and biocompatible.AA could be easily and abundantly extracted from natural fruits or vegetables.It provides a new guide for the green,mild,and efficient dissolution of LCO aiming at sustainable recovery of spent LIBs.Yu Chen Yanlong Wang Yue Bai Minghui Feng Fengyi Zhou Yanhong Lu Yuting Guo Yixuan Zhang Tiancheng Mu 2023Green Chemical Engineering2023,4,3:0
13Cryo-EM structures for the Mycobacterium tuberculosis iron-loaded siderophore transporter IrtAB显示文摘The adenosine 5'-triphosphate(ATP)-binding cassette(ABC)transporter,IrtAB,plays a vital role in the replication and viability of Mycobacterium tuberculosis(Mtb),where its function is to import iron-loaded siderophores.Unusually,it adopts the canonical type IV exporter fold.Herein,we report the structure of unliganded Mtb IrtAB and its structure in complex with ATP,ADP,or ATP analogue(AMP-PNP)at resolutions ranging from 2.8 to 3.5Å.The structure of IrtAB bound ATP-Mg2+shows a“head-to-tail”dimer of nucleotide-binding domains(NBDs),a closed amphipathic cavity within the transmembrane domains(TMDs),and a metal ion liganded to three histidine residues of IrtA in the cavity.Cryo-electron microscopy(Cryo-EM)structures and ATP hydrolysis assays show that the NBD of IrtA has a higher affinity for nucleotides and increased ATPase activity compared with IrtB.Moreover,the metal ion located in the TM region of IrtA is critical for the stabilization of the conformation of IrtAB during the transport cycle.This study provides a structural basis to explain the ATP-driven conformational changes that occur in IrtAB.Shan Sun Yan Gao Xiaolin Yang Xiuna Yang Tianyu Hu Jingxi Liang Zhiqi Xiong Yuting Ran Pengxuan Ren Fang Bai Luke WGuddat Haitao Yang Zihe Rao Bing Zhang 2023Protein & Cell2023,14,6:0
14SUMOylation-triggered ALIX activation modulates extracellular vesicles circTLCD4-RWDD3 to promote lymphatic metastasis of non-small cell lung cancer显示文摘Lymph node(LN)metastasis is one of the predominant metastatic routes of non-small cell lung cancer(NSCLC)and is considered as a leading cause for the unsatisfactory prognosis of patients.Although lymphangiogenesis is well-recognized as a crucial process in mediating LN metastasis,the regulatory mechanism involving lymphangiogenesis and LN metastasis in NSCLC remains unclear.In this study,we employed high-throughput sequencing to identify a novel circular RNA(circRNA),circTLCD4-RWDD3,which was significantly upregulated in extracellular vesicles(EVs)from LN metastatic NSCLC and was positively associated with deteriorated OS and DFS of patients with NSCLC from multicenter clinical cohort.Downregulating the expression of EV-packaged circTLCD4-RWDD3 inhibited lymphangiogenesis and LN metastasis of NSCLC both in vitro and in vivo.Mechanically,circTLCD4-RWDD3 physically interacted with hnRNPA2B1 and mediated the SUMO2 modification at K108 residue of hnRNPA2B1 by upregulating UBC9.Subsequently,circTLCD4-RWDD3-induced SUMOylated hnRNPA2B1 was recognized by the SUMO interaction motif(SIM)of ALIX and activated ALIX to recruit ESCRT-III,thereby facilitating the sorting of circTLCD4-RWDD3 into NSCLC cell-derived EVs.Moreover,EV-packaged circTLCD4-RWDD3 was internalized by lymphatic endothelial cells to activate the transcription of PROX1,resulting in the lymphangiogenesis and LN metastasis of NSCLC.Importantly,blocking EV-mediated transmission of circTLCD4-RWDD3 via mutating SIM in ALIX or K108 residue of hnRNPA2B1 inhibited the lymphangiogenesis and LN metastasis of NSCLC in vivo.Our findings reveal a precise mechanism underlying SUMOylated hnRNPA2B1-induced EV packaging of circTLCD4-RWDD3 in facilitating LN metastasis of NSCLC,suggesting that EV-packaged circTLCD4-RWDD3 could be a potential therapeutic target against LN metastatic NSCLC.Xiayao Diao Chao Guo Hanhao Zheng Ke Zhao Yuming Luo Mingjie An Yan Lin Jiancheng Chen Yuanlong Li Yuting Li Xuehan Gao Jiaqi Zhang Mengxin Zhou Wenliang Bai Lei Liu Guige Wang Lanjun Zhang Xiaotian He Rusi Zhang Zhihua Li Changhao Chen Shanqing Li 2023Signal Transduction and Targeted Therapy2023,8,12:0
15Sensing Mechanism of Excited-State Intermolecular Hydrogen Bond for Phthalimide: Indispensable Role of Dimethyl Sulfoxide显示文摘Excited-state hydrogen bond strongly affects the intramolecular charge conversion process,which is very suitable for the design and development of high-performance fluorescent probes.However,as one of the most common solvents or additives used in sensing,the role of dimethyl sulfoxide(DMSO)in the system of the excited-state hydrogen bond is seldom explored.As the goal of this research,we investigated the sensing mechanism of a C0RM3-green fluorescent probe system for carbon monoxide releasing molecule(CORM-3)detection and tracking in vivo,through quantum chemistry calculations based on density-functional-theory(DFT)/time-dependent density-functional-theory(TDDFT)methods.Based on the analysis of the solvent effect of DMSO by the reduced density gradient function and IR spectroscopy,we provided a new strategy to explain the fluorescence mechanism.Subsequently,we verified the result through the potential energy curve of Phthalimide(PTI,the reduced product of C0RM3-green).The excited-state hydrogen bond between PTI and DMSO promotes radiation transition and leads to obvious difference in the photophysical properties of PTI and PTI-DMSO.Dongdong Wang Tianxin Bai Xue Wang Yuting Xiong Yahui Zhang Zhenqiang Shi Fusheng Zhang Wenqi Lu Guangyan Qing 2021Chinese Journal of Chemistry2021,39,5:0
16A Study on the Task Analysis and Performance Evaluation of Carved Lacquer Craft Inheritors in Novice Stage显示文摘The carved lacquer craft,a gem of traditional Chinese crafts,boasts a history of over 2,000 years and features craftsmanship of a superior order.This study attempts to investigate the typical tasks and learning result evaluation of carved lacquer apprentices at the novice stage by the method of qualitative research with 11 carved lacquer craft inheritors of a studio of a carved lacquer master.It is discovered that the design of carved lacquer draft sketches,the design of carved lacquer patterns,and the making and use of carved lacquer tools are typical tasks of novice apprentices,while the modeling and aesthetics of works,carving skills,and the level of interaction with the carved lacquer community are important criteria for evaluating the development of the skills of novice apprentices.BAI Bin LIU Yuting LYU Xinshan 2021Cultural and Religious Studies2021,9,4:0
