| 1 | Tissue-specific transcription reprogramming promotes liver metastasis of colorectal cancer显示文摘Metastasis,the development of secondary malignant growths at a distance from a primary tumor,is the cause of death for 90%of cancer patients,but little is known about how metastatic cancer cells adapt to and colonize new tissue environments.Here,using clinical samples,patient-derived xenograft(PDX)samples,PDX cells,and primary/metastatic cell lines,we discovered that liver metastatic colorectal cancer(CRC)cells lose their colon-specific gene transcription program yet gain a liver-specific gene transcription program.We showed that this transcription reprogramming is driven by a reshaped epigenetic landscape of both typical enhancers and super-enhancers.Further,we identified that the liver-specific transcription factors FOXA2 and HNF1A can bind to the gained enhancers and activate the liver-specific gene transcription,thereby driving CRC liver metastasis.Importantly,similar transcription reprogramming can be observed in multiple cancer types.Our data suggest that reprogrammed tissue-specific transcription promotes metastasis and should be targeted therapeutically. | Shuaishuai Teng Yang Eric Li Ming Yang Rui Qi Yiming Huang Qianyu Wang Yanmei Zhang Shanwen Chen Shasha Li Kequan Lin Yang Cao Qunsheng Ji Qingyang Gu Yujing Cheng Zai Chang Wei Guo Pengyuan Wang Ivan Garcia-Bassets Zhi John Lu Dong Wang | 2020 | Cell Research2020，30，1： | 11 |
| 2 | Effect of Cyclocarya paliurus polysaccharides on streptozotocin-induced diabetic nephropathy in rats显示文摘OBJEVTIVE:To investigate the efficacy of Cyclocarya paliurus(C.paliurus)polysaccharides on streptozotocin-induced diabetic nephropathy in rats.METHODS:Rats were divided into 6 groups,including group of normal control,group of diabetic control,group of metformin treatment,low-dose group of C.paliurus polysaccharides treatment,middle-dose group of C.paliurus polysaccharides treatment and high-dose group of C.paliurus polysaccharides treatment.Histological analysis of kidney was analyzed using hematoxilin and eosin.Levels of blood glucose,creatinine,urea,uric acid were determined by spectrophotometry.Anti-oxidative enzymes were measured by real-time polymerase chain reaction(PCR)and enzyme-linked immunosorbent assay(ELISA).Advanced glycation end products(AGEs)and transforming growth factor-β1(TGF-β1)level was measured by ELISA.RESULTS:Abnormal changes were observed in the group of diabetic control characterized by atrophy of the renal glomeruli with hypercellularity,congestion of glomerular tufts,dilation of the renal spaces,and degeneration of renal tubule.Compared with that of normal group,blood glucose,creatinine,urea,uric acid level was significantly increased in the group of diabetic control.Superoxide dismutase,catalase,glutathione peroxidase,glutathione reductase level was significantly decreased,but AGEs and TGF-β1 level was significantly increased.By contrast,administration of C.paliurus polysaccharides and metformin could reverse the above-mentioned results of the group of diabetic control,especially in the high-dose group of C.paliurus polysaccharides.CONCLUSION:Our findings suggest that C.paliurus polysaccharides may play a protecting role for nephropathy of diabetic rats by lowering glucose,creatinine,urea,uric acid level,enhancing the antioxidative ability,and reducing AGEs and TGF-β1 expression. | Xia Xichao Mao Dongxue Dai Hongmei Wu Xi Zhang Zuyuan Wang Huaying Zhou Wenwen Dong Yanmei Wang Mengqi Li Yuan Shao Xiangyang Ouyang Jingfeng | 2020 | Journal of Traditional Chinese Medicine2020，40，6： | 9 |
| 3 | 3D C_f/SiBCN composites prepared by an improved polymer infiltration and pyrolysis显示文摘Using liquid poly(methylvinyl)borosilazanes(PMVBSZ)as precursor,carbon fiber reinforced SiBCN matrix composites(C_f/SiBCN)were fabricated by a modified polymer infiltration and pyrolysis(PIP)process.With dicumyl peroxide added as cross-linking agent,the PMVBSZ could be solidified at a low temperature of 120℃,leading to a high ceramic yield of~70%.The cross-linking mechanism and ceramization processes of the precursor were investigated in detail.Moreover,a modified infiltration technology was developed,which improved the efficiency and protected the precursor against moist air during PIP.Consequently,the obtained C_f/SiBCN composites had an oxygen content of around 1.22 wt%.Benefiting from the high ceramic yield and high efficiency of the modified PIP,C_f/SiBCN composites with an open porosity of~10%and uniform microstructure were obtained after only 7 cycles of PIP.The flexural strength and fracture toughness of the derived C_f/SiBCN composites were 371 MPa and 12.9 MPa·m^(1/2),respectively.This work provides a potential route for the fabrication of high performance C_f/SiBCN composites. | Qi DING Dewei NI Zhen WANG Hao ZHONG Hongda WANG Haijun ZHOU Yanmei KAN Shaoming DONG | 2018 | Journal of Advanced Ceramics2018，7，3： | 9 |
| 4 | Super-resolution fluorescence-assisted diffraction computational tomography reveals the threedimensional landscape of the cellular organelle interactome显示文摘The emergence of super-resolution(SR)fluorescence microscopy has rejuvenated the search for new cellular substructures.However,SR fluorescence microscopy achieves high contrast at the expense of a holistic view of the interacting partners and surrounding environment.Thus,we developed SR fluorescence-assisted diffraction computational tomography(SR-FACT),which combines label-free three-dimensional optical diffraction tomography(ODT)with two-dimensional fluorescence Hessian structured illumination microscopy.The ODT module is capable of resolving the mitochondria,lipid droplets,the nuclear membrane,chromosomes,the tubular endoplasmic reticulum,and lysosomes.Using dual-mode correlated live-cell imaging for a prolonged period of time,we observed novel subcellular structures named dark-vacuole bodies,the majority of which originate from densely populated perinuclear regions,and intensively interact with organelles such as the mitochondria and the nuclear membrane before ultimately collapsing into the plasma membrane.This work demonstrates the unique capabilities of SR-FACT,which suggests its wide applicability in cell biology in general. | Dashan Dong Xiaoshuai Huang Liuju Li Heng Mao Yanquan Mo Guangyi Zhang Zhe Zhang Jiayu Shen Wei Liu Zeming Wu Guanghui Liu Yanmei Liu Hong Yang Qihuang Gong Kebin Shi Liangyi Chen | 2020 | Light(Science & Applications)2020，9，1： | 7 |
| 5 | Reaction mechanism and microstructure development of ZrSi_(2) melt-infiltrated C_(f)/SiC-ZrC-ZrB_(2) composites:The influence of preform pore structures显示文摘Reactive melt infiltration(RMI)is an effective method for fabrication of highly dense carbon fiber reinforced ultra-high temperature ceramic matrix composites(Cf/UHTCs).In this work,C_(f)/SiC-ZrC-ZrB_(2)composites were fabricated by infiltrating ZrSi_(2)melt into porous C_(f)/B_(4)C-C preforms,where the physical and chemical reactions involved during the RMI process were identified and analyzed.Inhomogeneous infiltration between the inter-and intra-bundle pores was revealed,and was found to be strongly related to the pore structures of the C_(f)/B_(4)C-C preform.It is indicated that the inhomogeneous infiltration can be mitigated remarkably with increasing porosity and pore size of the preform.The effect of pore size on the RMI process was also investigated by a quantitative model,which agrees very well with the experiment results.It further indicates that the inhomogeneous infiltration can also be relieved at elevated RMI temperature.However,excessive infiltration at elevated temperature or more porous preform may cause serious erosion on interphase and fibers,leading to mechanical properties deterioration of the final composites. | Xiaowu Chen Dewei Ni Yanmei Kan Youlin Jiang Haijun Zhou Zhen Wang Shaoming Dong | 2018 | Journal of Materiomics2018，4，3： | 5 |
| 6 | The chromosome-based lavender genome provides new in sights into Lamiaceae evolution and terpenoid biosynthesis显示文摘The aromatic shrub Lavandula angustifolia produces various volatile terpenoids that serve as resources for essential oils and function in plant-insect communication.To better understand the genetic basis of the terpenoid diversity in lavender,we present a high-quality reference genome for the Chinese lavender cultivar‘Jingxun 2'using PacBio and Hi-C technologies to anchor the 894.50 Mb genome assembly into 27 pseudochromosomes.In addition to the y triplication event,lavender underwent two rounds of whole-genome duplication(WGD)during the Eocene-Oligocene(29.6 MYA)and Miocene-Pliocene(6.9 MYA)transitions.As a result of tandem duplications and lineage-specific WGDs,gene families related to terpenoid biosynthesis in lavender are substantially expanded compared to those of five other species in Lamiaceae.Many terpenoid biosynthesis transcripts are abundant in glandular trichomes.We further integrated the contents of ecologically functional terpenoids and coexpressed terpenoid biosynthetic genes to construct terpenoid-gene networks.Typical gene clusters,including TPS-TPS,TPS-CYP450,and TPS-BAHD,linked with compounds that primarily function as attractants or repellents,were identified by their similar patterns of change during flower development or in response to methyl jasmonate.Comprehensive analysis of the genetic basis of the production of volatiles in lavender could serve as a foundation for future research into lavender evolution,phytochemistry,and ecology. | Jingrui Li Yiming Wang Yanmei Dong Wenying Zhang Di Wang Hongtong Bai Kui Li Hui Li Lei Shi | 2021 | Horticulture Research2021，8，1： | 5 |
| 7 | An AIEE polyelectrolyte as a light-up fluorescent probe for heparin sensing in full detection range显示文摘Polyelectrolyte PTPEPyH, containing tetraphenylethene (TPE) and pyridinium, was synthesized. Its optical properties were investigated with spectroscopies and the results showed that there were two emission-enhanced stages in the interaction between positive-charged PTPEPyH and negative-charged biomacromolecule heparin. The mechanism was very different due to the reduced non-radiative energy loss and the change of surroundings. The polyelectrolyte PTPEPyH, compared with ChS and HA, also showed high selectivity for heparin in the buffer solution and could be used as a potential bio-probe for heparin quantification in the clinical full range. | CHEN DongYang SHI JianBing WU YanMei TONG Bin ZHI JunGe DONG YuPing | 2013 | Science China Chemistry2013，56，9： | 2 |
| 8 | The CRL3^(BTBD9) E3 ubiquitin ligase complex targets TNFAIP1 for degradation to suppress cancer cell migration显示文摘Tumor necrosis factor alpha-induced protein 1(TNFAIP1)modulates a plethora of important biological processes,including tumorigenesis and cancer cell migration.However,the regulatory mechanism of TNFAIP1 degradation remains largely elusive.In the present study,with a label-free quantitative proteomic approach,TNFAIP1 was identified as a novel ubiquitin target of the Cullin-RING E3 ubiquitin ligase(CRL)complex.More importantly,Cul3-ROC1(CRL3),a subfamily of CRLs,was identified to specifically interact with TNFAIP1 and promote its polyubiquitination and degradation.Mechanistically,BTBD9,a specific adaptor component of CRL3 complex,was further defined to bind and promote the ubiquitination and degradation of TNFAIP1 in cells.As such,downregulation of BTBD9 promoted lung cancer cell migration by upregulating the expression of TNFAIP1,whereas TNFAIP1 deletion abrogated this effect.Finally,bioinformatics and clinical sample analyses revealed that BTBD9 was downregulated while TNFAIP1 was overexpressed in human lung cancer,which was associated with poor overall survival of patients.Taken together,these findings reveal a previously unrecognized mechanism by which the CRL3^(BTBD9) ubiquitin ligase controls TNFAIP1 degradation to regulate cancer cell migration. | Lihui Li Wenjuan Zhang Yue Liu Xiaojun Liu Lili Cai Jihui Kang Yunjing Zhang Wenlian Chen Changsheng Dong Yanmei Zhang Mingsong Wang Wenyi Wei Lijun Jia | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 2 |

| 11 | Cell osteogenic bioactivity mediated precisely by varying scaled micro-pits on ordered micro/nano hierarchical structures of titanium显示文摘Hierarchical surface structures with micro–nano scale play a crucial role in regulation of cell proliferation and osteogenic differentiation.It has been proven that cells are extremely sensitive to the nanoscaled structure and show multifarious phenotypes.Though a vital function of microstructure on osseointegration has been confirmed,the cell performances response to different microscaled structure is needed to be further dissected and in depth understood.In this work,the ordered micro–nano hierarchical structures with varying micro-scaled pits were precisely fabricated on titanium successfully by the combination of electrochemical,chemical etching and anodization as well.In vitro systematical assessments indicated that the micro–nano multilevel structures on titanium exhibited excellent cells adhesion and spreading ability,as well as steerable proliferation and osteogenic differentiation behaviors.It is shown that smaller micro-pits and lower roughness of the hierarchical structures enabled faster cell propagation.Despite cell growth was delayed on micro–nano titanium with relatively larger cell-match-size micro-pits and roughness,osteogenic-specific genes were significantly elevated.Furthermore,the alkaline phosphatase activity,collagen secretion and extracellular matrix mineralization of MC3T3-E1 on multiscaled titanium were suppressed by a large margin after adding IWP-2(an inhibitor of Wnt/b-catenin signal pathway),indicating this pathway played a crucial part in cell osteogenic differentiation modulated by micro–nano structures. | Yanmei Zhang Xiankuan Wang Yaxian Li Jianhe Liang Pinliang Jiang Qiaoling Huang Yun Yang Hongping Duan Xiang Dong Gang Rui Changjian Lin | 2022 | Regenerative Biomaterials2022，9，1： | 1 |

| 13 | Electrodeposited synthesis of self-supported Ni-P cathode for efficient electrocatalytic hydrogen generation显示文摘One of the key challenges for electrochemical water splitting is the development of low-cost and efficient hydrogen evolution cathode. In this work, a self-supported Ni-P cathode was synthesized by a facile electrodeposition method. The composition and morphology were characterized by X-ray diffraction,X-ray photoelectron spectroscopy, scanning electron microscopy and transmission electron microscopy.The Ni-P cathode performed low onset over-potential, good catalytic activity and long-term stability under neutral and alkaline conditions. The mechanism of Ni-P electrode for hydrogen production was discussed by electrochemical impedance spectroscopy. The excellent performance of Ni-P cathode was mainly attributed to the synergistic effect of phosphate anions and the self-supported feature. | Ruixian Wu Yuming Dong Pingping Jiang Guangli Wang Yanmei Chen Xiuming Wu | 2016 | Progress in Natural Science:Materials International2016，26，3： | 1 |
| 14 | Alkaline 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 | 2022 | Bioactive Materials2022，7，9： | 1 |
| 15 | Recent advances in chemical protein synthesis:method developments and biological applications显示文摘The central dogma of modern biology underscores the pivotal roles proteins play in diverse biological processes,the study of which necessitates advanced methods to produce proteins with precision and versatility.Chemical protein synthesis,a powerful approach utilizing chemical reactions for the de novo construction of structurally accurate proteins,has emerged as a transformative tool for studying proteins and generating protein derivatives/mimics inaccessible by natural biological machinery,including post-translationally modified proteins,proteins comprised of unnatural amino acids,as well as mirror-image proteins.This review summarizes recent strides in synthetic method developments for chemical protein synthesis,including innovative techniques in solid-phase peptide synthesis,the challenges presented by difficult sequences in either synthesis or folding and the exploration of novel ligation reactions using both chemical and enzymatic methods.Furthermore,the review also delves into newly developed protocols for site-selective protein modifications and the generation of stapled or macrocyclized peptides/miniproteins,highlighting the power of chemical methods to make structurally diverse proteins.Recent applications of synthetic proteins in investigating post-translational modifications(phosphorylation,lipidation,glycosylation,ubiquitination,etc.),mirror-image biological processes and drug development are further discussed.Together,these topics provide a comprehensive overview of the current landscape of chemical protein synthesis. | Suwei Dong Ji-Shen Zheng Yiming Li Huan Wang Gong Chen Yongxiang Chen Gemin Fang Jun Guo Chunmao He Honggang Hu Xuechen Li Yanmei Li Zigang Li Man Pan Shan Tang Changlin Tian Ping Wang Bian Wu Chuanliu Wu Junfeng Zhao Lei Liu | 2024 | Science China Chemistry2024，67，4： | 0 |
| 16 | Compositional change in human enamel irradiated with MIR free electron laser显示文摘The purpose of this study was to investigate compositional changes in human enamel irradiated with the free electron laser (FEL). The exposure on dental enamel at the wavelength of 9.64 μm was observed with the Beijing free electron laser. The distribution of elements in the irradiated or non-irradiated enamel was measured by scanning electron microscope (SEM) with energy-dispersive spectroscopy and synchrotron radiation X-ray fluorescence (SRXRF) in Beijing Synchrotron Radiation Facility (BSRF). The results showed that the P/Ca ratio in the ablation region of enamel at the maximum wavelength of infrared absorption was obviously smaller than that at the non-maximum wavelength. In the ablation region the ratios of P/Ca and Ca/Sr were smaller than those in the non-ablation region. The distributions of P, Ca and Sr in the ablation region were heterogeneous due to the element change caused by FEL irradiation. | LIU Nianqing LI Yonggui ZHU Junbiao ZHANG Liwen WANG Mingkai WU Gang YANG Xueping Li Guangcheng Huang Yuying DONG Yanmei GAO Xuejun | 2001 | Chinese Science Bulletin2001，46，23： | 0 |
| 17 | Exploring the links between gut microbiome changes and irritable bowel syndrome in Han populations in the Tibetan Plateau显示文摘The gut microbiome shows changes under a plateau environment,while the disbalance of intestinal microbiota plays an important role in the pathogenesis of irritable bowel syndrome(IBS);however,the relationship between the two remains unexplored.In this work,we followed up a healthy cohort for up to a year before and after living in a plateau environment and performed 16S ribosomal RNA(rRNA)sequencing analysis of their fecal samples.Through evaluating the participants’clinical symptoms,combined with an IBS questionnaire,we screened the IBS sub-population in our cohort.The sequencing results showed that a high-altitude environment could lead to changes in the diversity and composition of gut flora.In addition,we found that the longer the time volunteers spent in the plateau environment,the more similar their gut microbiota composition and abundance became compared to those before entering the plateau,and IBS symptoms were significantly alleviated.Therefore,we speculated that the plateau may be a special environment that induces IBS.The taxonomic units g_Alistipes,g_Oscillospira,and s_Ruminococcus_torques,which had been proved to play important roles in IBS pathogenesis,were also abundant in the IBS cohort at high altitudes.Overall,the disbalance of gut microbiota induced by the plateau environment contributed to the high frequency of IBS and the psychosocial abnormalities associated with IBS.Our results prompt further research to elucidate the relevant mechanism. | Xingguang ZHANG Wei XU Weilong ZHONG Wencheng ZHANG Cheng YANG Lisa DUAN Haiyan NIU Yanmei DONG Taotao LIU Shihai XIA Bangmao WANG | 2023 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023，24，9： | 0 |
