| 1 | Exosome-functionalized polyetheretherketone-based implant with immunomodulatory property for enhancing osseointegration显示文摘The host immune response effecting on biomaterials is critical to determine implant fates and bone regeneration property.Bone marrow stem cells(BMSCs)derived exosomes(Exos)contain multiple biosignal molecules and have been demonstrated to exhibit immunomodulatory functions.Herein,we develop a BMSC-derived Exos-functionalized implant to accelerate bone integration by immunoregulation.BMSC-derived Exos were reversibly incorporated on tannic acid(TA)modified sulfonated polyetheretherketone(SPEEK)via the strong interaction of TA with biomacromolecules.The slowly released Exos from SPEEK can be phagocytosed by co-cultured cells,which could efficiently improve the biocompatibilities of SPEEK.In vitro results showed the Exos loaded SPEEK promoted macrophage M2 polarization via the NF-κB pathway to enhance BMSCs osteogenic differentiation.Further in vivo rat air-pouch model and rat femoral drilling model assessment of Exos loaded SPEEK revealed efficient macrophage M2 polarization,desirable new bone formation,and satisfactory osseointegration.Thus,BMSC-derived Exos-functionalized implant exerted osteoimmunomodulation effect to promote osteogenesis. | Lei Fan Pengfei Guan Cairong Xiao Huiquan Wen Qiyou Wang Can Liu Yian Luo Limin Ma Guoxin Tan Peng Yu Lei Zhou Chengyun Ning | 2021 | Bioactive Materials2021，6，9： | 11 |
| 2 | Mechanically exfoliated MoS_(2) nanosheets decorated with SnS_(2) nanoparticles for high-stability gas sensors at room temperature显示文摘Due to its unique physical,chemical and surface electronic properties,molybdenum disulfide(MoS_(2))nanosheets open up a new avenue for nitrogen dioxide(NO2)detection at room temperature.Nevertheless,the gas sensing properties of pure MoS_(2) nanosheets are inevitably degenerated by the adsorption of atmospheric oxygen,which results in weak stability for MoS_(2)-based gas sensors.Reducing surface defects and constructing heterojunctions may be effective strategies to improve the gas sensing properties of MoS_(2) nanosheets.In this work,we design a novel nanocomposite based on MoS_(2) nanosheets decorated with tin disulfide(SnS_(2))nanoparticles(MoS_(2)/SnS_(2))via combining the mechanical exfoliation method with the facile hydrothermal method.The experimental results indicate that,after surfaces decoration with SnS_(2) nanoparticles,the as-prepared gas sensor based on MoS_(2)/SnS_(2) nanocomposites exhibits reliable long-term stability with the maximum response value drift of less than 3%at room temperature.Moreover,the MoS_(2)/SnS_(2) sensor also possesses desirable gas sensing properties upon NO_(2) at room temperature,such as high sensitivity,rapid response/recovery speed(28 s/3 s,5×10^(-6) NO_(2)),satisfactory selectivity,favorable repeatability and reversibility.The improved gas sensing properties of MoS_(2)/SnS_(2) nanocomposites can be attributed to the unique electronic properties of MoS 2 nanosheets with the fewer layers structure and the competitive adsorption effect of SnS_(2) nanoparticles.This work elucidates that SnS_(2) nanoparticles serving as an effective antioxidative decoration can promote the stability of MoS_(2) nanosheets,providing a promising approach to achieve high-stability NO2 gas sensors at room temperature. | Jia-Bei Liu Jin-Yong Hu Can Liu Yu-Ming Tan Xiang Peng Yong Zhang | 2021 | Rare Metals2021，40，6： | 5 |
| 3 | Omics-based integrated analysis identified ATRX as a biomarker associated with glioma diagnosis and prognosis显示文摘Objective:ATRX is a multifunctional protein that is tightly regulated by and implicated in transcriptional regulation and chromatin remodeling.Numerous studies have shown that genetic alterations in ATRX play a significant role in gliomas.This study aims to further determine the relationship between ATRX and glioma prognosis and identify possible mechanisms for exploring the biological significance of ATRX using large data sets.Methods:We used The Cancer Genome Atlas(TCGA)database and 130 immunohistochemical results to confirm the difference in ATRX mutations in high-and low-grade gliomas.An online analysis of the TCGA glioma datasets using the cBioPortal platform was performed to study the relationship between ATRX mutations and IDH1,TP53,CDKN2 A and CDKN2 B mutations in the corresponding TCGA glioma dataset.In combination with clinical pathology data,the biological significance of the relationships were analyzed.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway analyses and annotations of all adjacent genes in the network were performedin the Database for Annotation,Visualization and Integrated Discovery(DAVID)and R language.A protein-protein interaction(PPI)network was constructed,and the interactions of all adjacent nodes were analyzed by the String database and using Cytoscape software.Results:In the selected TCGA glioma datasets,a total of 2,228 patients were queried,21%of whom had ATRX alterations,which co-occurred frequently with TP53 and IDH1 mutations.ATRX alterations are associated with multiple critical molecular events,which results in a significantly improved overall survival(OS)rate.In low-grade gliomas,ATRX mutations are significantly associated with multiple important molecular events,such as ZNF274 and FDXR at mRNA and protein levels.A functional cluster analysis revealed that these genes played a role in chromatin binding and P53,and a link was observed between ATRX and IDH1 and TP53 in the interaction network.ATRX and TP53 are important nodes in the network and have potential links with the blood oxygen imbalance.Conclusions:ATRX mutations have clinical implications for the molecular diagnosis of gliomas and can provide diagnostic and prognostic information for gliomas.ATRX is expected to serve as a new therapeutic target. | Yingbin Xie Yanli Tan Chao Yang Xuehao Zhang Can Xu Xiaoxia Qiao Jianglong Xu Shaohui Tian Chuan Fang Chunsheng Kang | 2019 | Cancer Biology & Medicine2019，16，4： | 5 |
| 4 | Circular RNA circCCNB1 inhibits the migration and invasion of nasopharyngeal carcinoma through binding and stabilizing TJP1 mRNA显示文摘Nasopharyngeal carcinoma(NPC)is a malignant tumor that usually occurs in people from Southeast Asia and Southern China.NPC is prone to migration and invasion,leading to poor prognosis.A large number of circular RNAs(circ RNAs)exacerbate the process of metastasis in NPC;however,their underlying mechanisms remain unclear.We found that the circular RNA circ CCNB1,encoded by the oncogene CCNB1,was downregulated in NPC biopsies and cell lines.In vitro assays show that circ CCNB1 inhibits NPC cell migration and invasion.Moreover,circ CCNB1 induces a protein,nuclear factor 90(NF90),to bind and prolong the half-life of tight junction protein 1(TJP1)m RNA.Upregulation of TJP1 enhances tight junctions between cancer cells and inhibits NPC cell migration and invasion.This study reveals a novel biological function of circ CCNB1 in the migration and invasion of NPC by enhancing the tight junctions of cancer cells by binding to NF90 proteins and TJP1 m RNA,and may provide a potential therapeutic target for NPC. | Mengyao Zhao Yian Wang Fenghua Tan Lingyun Liu Xiangchan Hou Chunmei Fan Le Tang Yongzhen Mo Yumin Wang Qijia Yan Zhaojian Gong Zheng Li Qianjin Liao Can Guo He Huang Xi Zeng Guiyuan Li Zhaoyang Zeng Wei Xiong Fuyan Wang | 2022 | Science China(Life Sciences)2022，65，11： | 4 |
| 5 | Phosphorylation inhibition of protein-tyrosine phosphatase 1B tyrosine-152 induces bone regeneration coupled with angiogenesis for bone tissue engineering显示文摘A close relationship has been reported to exist between cadherin-mediated cell-cell adhesion and integrin-mediated cell mobility,and protein tyrosine phosphatase 1B(PTP1B)may be involved in maintaining this homeostasis.The stable residence of mesenchymal stem cells(MSCs)and endothelial cells(ECs)in their niches is closely related to the regulation of PTP1B.However,the exact role of the departure of MSCs and ECs from their niches during bone regeneration is largely unknown.Here,we show that the phosphorylation state of PTP1B tyrosine-152(Y152)plays a central role in initiating the departure of these cells from their niches and their subsequent recruitment to bone defects.Based on our previous design of a PTP1B Y152 region-mimicking peptide(152RM)that significantly inhibits the phosphorylation of PTP1B Y152,further investigations revealed that 152RM enhanced cell migration partly via integrinαvβ3 and promoted MSCs osteogenic differentiation partly by inhibiting ATF3.Moreover,152RM induced type H vessels formation by activating Notch signaling.Demineralized bone matrix(DBM)scaffolds were fabricated with mesoporous silica nanoparticles(MSNs),and 152RM was then loaded onto them by electrostatic adsorption.The DBM-MSN/152RM scaffolds were demonstrated to induce bone formation and type H vessels expansion in vivo.In conclusion,our data reveal that 152RM contributes to bone formation by coupling osteogenesis with angiogenesis,which may offer a potential therapeutic strategy for bone defects. | Yong Tang Keyu Luo Yin Chen Yueqi Chen Rui Zhou Can Chen Jiulin Tan Moyuan Deng Qijie Dai Xueke Yu Jian Liu Chengmin Zhang Wenjie Wu Jianzhong Xu Shiwu Dong Fei Luo | 2021 | Bioactive Materials2021，6，7： | 3 |

| 7 | An injectable,self-healing,electroconductive extracellular matrix-based hydrogel for enhancing tissue repair after traumatic spinal cord injury显示文摘Injectable biomaterial-based treatment is a promising strategy to enhance tissue repair after traumatic spinal cord injury(SCI)by bridging cavity spaces.However,there are limited reports of injectable,electroconductive hydrogels with self-healing properties being employed for the treatment of traumatic SCI.Hence,a natural extracellular matrix(ECM)biopolymer(chondroitin sulphate and gelatin)-based hydrogel containing polypyrrole,which imparted electroconductive properties,is developed for traumatic SCI repair.The resulting hydrogels showed mechanical(~928 Pa)and conductive properties(4.49 mS/cm)similar to natural spinal cord tissues.Moreover,the hydrogels exhibited shear-thinning and self-healing abilities,which allows it to be effectively injected into the injury site and to fill the lesion cavity to accelerate the tissue repair of traumatic SCI.In vitro,electroconductive ECM hydrogels promoted neuronal differentiation,enhanced axon outgrowth,and inhibited astrocyte differentiation.The electroconductive ECM hydrogel activated endogenous neural stem cell neurogenesis in vivo(n=6),and induced myelinated axon regeneration into the lesion site via activation of the PI3K/AKT and MEK/ERK pathways,thereby achieving significant locomotor function restoration in rats with spinal cord injury(p<0.001,compared to SCI group).Overall,the injectable self-healing electroconductive ECM-based hydrogels developed in this study are ideal biomaterials for treatment of traumatic SCI. | Yian Luo Lei Fan Can Liu Huiquan Wen Shihuan Wang Pengfei Guan Dafu Chen Chengyun Ning Lei Zhou Guoxin Tan | 2022 | Bioactive Materials2022，7，1： | 2 |

| 9 | Generating Giant Membrane Vesicles from Live Cells with Preserved Cellular Properties显示文摘Biomimetic giant membrane vesicles,with size and lipid compositions comparable to cells,have been recognized as an attractive experimental alternative to living systems.Due to the similarity of their membrane structure to that of body cells,cell-derived giant plasma membrane vesicles have been used as a membrane model for studying lipid/protein behavior of plasma membranes.However,further application of biomimetic giant membrane vesicles has been hampered by the side-efects of chemical vesiculants and the utilization of osmotic bufer.We herein develop a facile strategy to derive giant membrane vesicles(GMVs)from mammalian cells in biofriendly medium with high yields.Tese GMVs preserve membrane properties and adaptability for surface modifcation and encapsulation of exogenous molecules,which would facilitate their potential biological applications.Moreover,by loading GMVs with therapeutic drugs,GMVs could be employed for drug transport to tumor cells,which represents another step forward in the biomedical application of giant membrane vesicles.Tis study highlights biocompatible GMVs with biomimicking membrane surface properties and adaptability as an ideal platform for drug delivery strategies with potential clinical applications. | Qiaoling Liu Cheng Bi Jiangling Li Xuejiao Liu Ruizi Peng Cheng Jin Yang Sun Yifan Lyu Hui Liu Huijing Wang Can Luo Weihong Tan | 2019 | Research2019，，1： | 2 |
| 10 | Fast response speed of mechanically exfoliated MoS2 modified by PbS in detecting NO2显示文摘MoS2,acting as a promising gas sensing material,has shown huge potential in monitoring of toxic and harmful gases at room temperature.However,MoS2-based gas sensors still suffer from poor gas sensing performance such as poor sensitivity,long response time.Constructing the hete ro structure is an effective approach to improve gas-sensing performance of MoS2.Herein,PbS@MoS2 composites synthesized by mechanical exfoliation combining with wet-chemical precipitation are used to investigate its performance in detecting NO2 at room temperature.The response value of PbS@MoS2 gas sensor against NO2 is significantly improved compared with the pure MoS2 gas sensor.At the same time,the modification with PbS also accelerates the response speed of MoS2,and the response time is almost reduced by two orders of magnitude,from hundreds of seconds to less than ten seconds.The enhanced response value and fast response time are mainly benefited from the modulation effect of NO2 to PbS@MoS2 heterostructure and the mechanically exfoliated MoS2 surface with few defects.This work can be expected to provide useful guidance for designing composite materials with excellent gas sensing properties. | Junjiang Tan Jinyong Hu Jianxu Ren Jinfeng Peng Can Liu Yiqiao Song Yong Zhang | 2020 | Chinese Chemical Letters2020，31，8： | 2 |
| 11 | Overexpression of OsSPL9 enhances accumulation of Cu in rice grain and improves its digestibility and metabolism显示文摘Copper(Cu)is an essential trace mineral element for all forms of life,and is an important structural component and co-factor for a variety of metalloenzymes(Pen^a et al.,1999;Bertinato and L'Abbe,2004).In humans,Cu deficiency is not common because of the ubiquitous occurrence of Cu and ease of gastrointestinal absorption(Zidar et al.,1977;Uauy et al.,1998).However,because of the low Cu content in most sources of feed,the use of Cu as a growth promoter to maximize animal production has been well documented in animal feeding(Braude,1945;Lu et al.,2010).Pre- | Mingfeng Tang Chuanshe Zhou Lu Meng Donghai Mao Can Peng Yuxing Zhu Daoyou Huang Zhiliang Tan Caiyan Chen Chengbing Liu Dechun Zhang | 2016 | Journal of Genetics and Genomics2016，43，11： | 2 |
| 12 | Inhibition of aberrant Hif1αactivation delays intervertebral disc degeneration in adult mice显示文摘The intervertebral disc(IVD) is the largest avascular tissue. Hypoxia-inducible factors(HIFs) play essential roles in regulating cellular adaptation in the IVD under physiological conditions. Disc degeneration disease(DDD) is one of the leading causes of disability, and current therapies are ineffective. This study sought to explore the role of HIFs in DDD pathogenesis in mice. The findings of this study showed that among HIF family members, Hif1α was significantly upregulated in cartilaginous endplate(EP) and annulus fibrosus(AF) tissues from human DDD patients and two mouse models of DDD compared with controls. Conditional deletion of the E3 ubiquitin ligase Vhl in EP and AF tissues of adult mice resulted in upregulated Hif1α expression and age-dependent IVD degeneration. Aberrant Hif1α activation enhanced glycolytic metabolism and suppressed mitochondrial function. On the other hand, genetic ablation of the Hif1α gene delayed DDD pathogenesis in Vhl-deficient mice. Administration of 2-methoxyestradiol(2ME2), a selective Hif1α inhibitor, attenuated experimental IVD degeneration in mice. The findings of this study show that aberrant Hif1α activation in EP and AF tissues induces pathological changes in DDD, implying that inhibition of aberrant Hif1α activity is a potential therapeutic strategy for DDD. | Zuqiang Wang Hangang Chen Qiaoyan Tan Junlan Huang Siru Zhou Fengtao Luo Dali Zhang Jing Yang Can Li Bo Chen Xianding Sun Liang Kuang Wanling Jiang Zhenhong Ni Quan Wang Shuai Chen Xiaolan Du Di Chen Chuxia Deng Liangjun Yin Lin Chen Yangli Xie | 2022 | Bone Research2022，10，1： | 1 |

| 19 | Self-curling electroconductive nerve dressing for enhancing peripheral nerve regeneration in diabetic rats显示文摘Conductive scaffolds have been shown to exert a therapeutic effect on patients suffering from peripheral nerve injuries(PNIs).However,conventional conductive conduits are made of rigid structures and have limited applications for impaired diabetic patients due to their mechanical mismatch with neural tissues and poor plasticity.We propose the development of biocompatible electroconductive hydrogels(ECHs)that are identical to a surgical dressing in this study.Based on excellent adhesive and self-healing properties,the thin film-like dressing can be easily attached to the injured nerve fibers,automatically warps a tubular structure without requiring any invasive techniques.The ECH offers an intimate and stable electrical bridge coupling with the electrogenic nerve tissues.The in vitro experiments indicated that the ECH promoted the migration and adhesion of the Schwann cells.Furthermore,the ECH facilitated axonal regeneration and remyelination in vitro and in vivo through the MEK/ERK pathway,thus preventing muscle denervation atrophy while retaining functional recovery.The results of this study are likely to facilitate the development of non-invasive treatment techniques for PNIs in diabetic patients utilizing electroconductive hydrogels. | Can Liu Lei Fan Zhenming Tian Huiquan Wen Lei Zhou Pengfei Guan Yian Luo Chuncheung Chan Guoxin Tan Chengyun Ning Limin Rong Bin Liu | 2021 | Bioactive Materials2021，6，11： | 1 |
