| 1 | Chimeric antigen receptor T cell targeting EGFRvIII for metastatic lung cancer therapy显示文摘Lung cancer is the most common incident cancer and the leading cause of cancer death. In recent years, the development of tumor immunotherapy especially chimeric antigen receptor T (CAR-T) cell has shown a promising future. Epidermal growth factor receptor variant III (EGFRvlll) is a tumor-specific mutation expressed in various types of tumors and has been detected in non-small cell lung cancer with a mutation rate of 10%. Thus, EGFRvIII is a potential antigen for targeted lung cancer therapy. In this study, CAR vectors were constructed and transfected into virus-packaging cells. Then, activated T cells were infected with retrovirus harvested from stable virus-producing single clone cell lines. CAR expression on the surfaces of the T cells was detected by flow cytometry and Western blot. The function of CAR-T targeting EGFRvIII was then evaluated. The EGFRvIII-CAR vector was successfully constructed and confirmed by DNA sequencing. A stable virus-producing cell line was produced from a single clone by limited dilution. The culture conditions for the cell line, including cell density, temperature, and culture medium were optimized. After infection with retrovirus, CAR was expressed on more than 90% of the T cells. The proliferation of CAR-T cells were induced by cytokine and specific antigen in vitro. More importantly, EGFRvIII-CART specifically and efficiently recognized and killed A549-EGFRvIII cells with an effector/target ratio of 10:1 by expressing and releasing cytokines, including perforin, granzyme B, IFN-γ, and TNF-α. The in vivo study indicated that the metastasis of A549-EGFRvIII cells in mice were inhibited by EGFRvIII-CART cells, and the survival of the mice was significantly prolonged with no serious side effects. EGFRvIII-CART showed significantly efficient antitumor activity against lung cancer cells expressing EGFRvlll in vivo and in vitro. Therefore, CAR-T targeting EGFRvIII is a potential therapeutic strategy in preventing recurrence and metastasis of lung cancer after surgery. | Zhao Zhang Jun Jiang Xiaodong Wu Mengyao Zhang Dan Luo Renyu Zhang Shiyou Li Youwen He Huijie Bian Zhinan Chen | 2019 | Frontiers of Medicine2019，13，1： | 11 |
| 2 | Onset of Xiashu loess deposition in southern China by 0.9 Ma and its implications for regional aridification显示文摘The Xiashu loess is a typical Quaternary eolian deposit in southern China and represents an important terrestrial paleoclimate archive in this low-latitude monsoon region. However, the chronological framework of Xiashu loess deposition has yet to be established. Determining the timing of the onset of Xiashu loess deposition will allow researchers to better understand late Quaternary aridification across the Asian continent, the evolution of the East Asian monsoon and regional environmental changes in subtropical regions. Therefore, in this study, a systematic chronological study of the Xiashu loess is conducted to answer this question. For the first time, magnetostratigraphic classification reveals that the Matuyama/Brunhes(M/B) reversal is present in the Xiashu loess at two sites in Jiangsu Province, the Qingshan profile at Yizheng and the Dagang core in Zhenjiang.Based on the results of magnetostratigraphy and optically stimulated luminescence(OSL) dating, the age of the lower boundary of the Xiashu loess is estimated to be approximately 0.9 Ma. Consequently, this Xiashu loess deposit is the oldest reported to date and is comparable in age to the red soil deposit in Xuancheng, Anhui Province. The onset of Xiashu loess deposition by 0.9 Ma represents the further expansion of arid range in Asia in the late Quaternary in response to significant aridification and winter monsoon strengthening in this subtropical region. We suggest that these climate changes were primarily driven by global cooling and an increase in high-latitude ice volume in the Northern Hemisphere and that the initiation of Xiashu loess accumulation was a regional response of southern China to the 0.9 Ma global cooling event. | Xusheng LI Zhiyong HAN Huayu LU Yingyong CHEN Yang LI Xiaokang YUAN Yuwen ZHOU Mengyao JIANG Cunjuan LV | 2018 | Science China Earth Sciences2018，61，3： | 11 |
| 3 | Near-infrared luminescent Nd^(3+)/Yb^(3+)-codoped metal-organic framework for ratiometric temperature sensing in physiological range显示文摘Self-calibrating luminescent thermometry employing luminescence within the optical transparency windows provides a promising prospect for temperature measurement in the biological fields.In this work,a new Nd^(3+)/Yb^(3+)-codoped metal-organic framework Nd_(0.95)Yb_(0.05)BPTC showing threedimensional anionic network,obtained by reacting ligand[1,1’-biphenyl]-3,3’,5,5’-tetracarboxylic acid(H4BPTC)with Nd^(3+)and Yb^(3+)ions under solvothermal conditions,is reported.Upon 808 nm photoexcitation,Nd_(0.95)Yb_(0.05)BPTC simultaneously emits the characteristic near-infrared luminescence of Nd^(3+)and Yb^(3+)ions based on the efficient energy transfer from Nd^(3+)to Yb^(3+)ions.In addition,the emission intensity ratio of Yb^(3+)and Nd^(3+)shows good exponential-like response to temperature in the physiological range of 293-323 K.The feature properties of Nd_(0.95)Yb_(0.05)BPTC include near-infrared absorption and emission,favorable temperature sensitivity and accurate temperature uncertainty,as well as good chemical stability,making such system useful in biomedical applications. | Chao Gu Yanyun Ding Xinghua Quan Mengyao Gong Jiulong Yu Dian Zhao Chunxia Li | 2021 | Journal of Rare Earths2021，39，9： | 4 |
| 4 | Electronic-property dependent interactions between tetracycline and graphene nanomaterials in aqueous solution显示文摘Understanding the interactions between graphene nanomaterials(GNMs) and antibiotics in aqueous solution is critical to both the engineering applications of GNMs and the assessment of their potential impact on the fate and transport of antibiotics in the aquatic environment. In this study, adsorption of one common antibiotic, tetracycline, by graphene oxide(GO) and reduced graphene oxide(RGO) was examined with multi-walled carbon nanotubes(MWCNTs) and graphite as comparison. The results showed that the tetracycline adsorption capacity by the four selected carbonaceous materials on the unit mass basis followed an order of GO > RGO > MWCNTs > graphite. Upon normalization by surface area,graphite, RGO and MWCNTs had almost the same high tetracycline adsorption affinity while GO exhibited the lowest. We proposed π-electron-property dependent interaction mechanisms to explain the observed different adsorption behaviors. Density functional theory(DFT) calculations suggested that the oxygen-containing functional groups on GO surface reduced its π-electron-donating ability, and thus decreased the π-based interactions between tetracycline and GO surface. Comparison of adsorption efficiency at different p H indicated that electrostatic interaction also played an important role in tetracycline-GO interactions. Site energy analysis confirmed a highly heterogeneous distribution of the binding sites and strong tetracycline binding affinity of GO surface. | Lin He Fei-fei Liu Mengyao Zhao Zhen Qi Xuefei Sun Muhammad Zaheer Afzal Xiaomin Sun Yanhui Li Jingcheng Hao Shuguang Wang | 2018 | Journal of Environmental Sciences2018，30，4： | 4 |
| 5 | Total plant performance evaluation based on big data: Visualization analysis of TE process显示文摘The performance evaluation of the process industry, which has been a popular topic nowadays, can not only find the weakness and verify the resilience and reliability of the process, but also provide some suggestions to improve the process benefits and efficiency. Nevertheless, the performance assessment principally concentrates upon some parts of the entire system at present, for example the controller assessment. Although some researches focus on the whole process, they aim at discovering the relationships between profit, society, policies and so forth, instead of relations between overall performance and some manipulated variables, that is, the total plant performance. According to the big data of different performance statuses, this paper proposes a hierarchical framework to select some structured logic rules from monitored variables to estimate the current state of the process. The variables related to safety and profits are regarded as key factors to performance evaluation. To better monitor the process state and observe the performance variation trend of the process, a classificationvisualization method based on kernel principal component analysis(KPCA) and self-organizing map(SOM) is established. The dimensions of big data produced by the process are first reduced by KPCA and then the processed data will be mapped into a two-dimensional grid chart by SOM to evaluate the performance status. The monitoring method is applied to the Tennessee Eastman process. Monitoring results indicate that off-line and on-line performance status can be well detected in a two-dimensional diagram. | Mengyao Li Wenli Du Feng Qian Weiming Zhong | 2018 | Chinese Journal of Chemical Engineering2018，26，8： | 4 |
| 6 | 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 |
| 7 | Microstructure and texture evolution of fine-grained Mg-Zn-Y-Nd alloy micro-tubes for biodegradable vascular stents processed by hot extrusion and rapid cooling显示文摘Magnesium alloys have narrow available slip result from close-packed hexagonal structure that limit their processing properties.In the recent work,the Mg-2Zn-0.46Y-0.5Nd,as materials for degradable stents,was applied to produce as-extruded micro-tube with an outer diameter of 3.0mm and a wall thickness of 0.35mm by hot extrusion with an extrusion ratio of 105:1 at 653K and rapid cooling.The fine microstructure of the dynamic recrystallization of as-extruded micro-tube could be preserved by rapid cooling such as water-cooled,resulting in more excellent mechanical properties relative to air-cooled micro-tube.The addition of rare earth elements Y and Nd results in continuous dynamic recrystallization dominated the dynamic recrystallization mechanism.During the hot extrusion process,the activation of the non-basal slip system,especially the pyramidal(c+a)slip,could significantly weaken the texture strength,and the as-extruded micro-tube exhibits weak'RE'texture components(011^(-)1)||ED and(1^(-)21^(-)1)||ED.Hence,the magnesium alloy micro-tube prepared by the rapid cooling has fine microstructure and weak texture,which is favorable for further process and governance. | Kaikai Guo Mengyao Liu Jianfeng Wang Yufeng Sun Weiqing Li Shijie Zhu Liguo Wang Shaokang Guan | 2020 | Journal of Magnesium and Alloys2020，8，3： | 3 |
| 8 | Self-powered,flexible,and ultrabroadband ultraviolet-terahertz photodetector based on a laser-reduced graphene oxide/CsPbBr3 composite显示文摘Self-powered and flexible ultrabroadband photodetectors(PDs)are desirable in a wide range of applications.The current PDs based on the photothermoelectric(PTE)effect have realized broadband photodetection.However,most of them express low photoresponse and lack of flexibility.In this work,high-performance,self-powered,and flexible PTE PDs based on laser-scribed reduced graphene oxide(LSG)∕CsPbBr3 are developed.The comparison experiment with LSG PD and fundamental electric properties show that the LSG∕CsPbBr3 device exhibits enhanced ultrabroadband photodetection performance covering ultraviolet to terahertz range with high photoresponsivity of 100 mA/W for 405 nm and 10 mA/W for 118μm at zero bias voltage,respectively.A response time of 18 ms and flexible experiment are also acquired at room temperature.Moreover,the PTE effect is fully discussed in the LSG∕CsPbBr3 device.This work demonstrates that LSG∕CsPbBr3 is a promising candidate for the construction of high-performance,flexible,and self-powered ultrabroadband PDs at room temperature. | YIFAN LI YATING ZHANG ZHILIANG CHEN QINGYAN LI TENGTENG LI MENGYAO LIHONGLIANG ZHAO QUAN SHENG WEI SHI JIANQUAN YAO | 2020 | Photonics Research2020，8，8： | 3 |
| 9 | Human activities and elevational constraints restrict ranging patterns of snub-nosed monkeys in a mountainous refuge显示文摘Both natural conditions and anthropogenic factors affect the survivability,distribution,and population density of wildlife.To understand the extent and how these factors drive species distributions,a detailed description of animal movement patterns in natural habitats is needed.In this study,we used satellite telemetry to monitor elevational ranges favored by endangered golden snub-nosed monkeys(Rhinopithecus roxellana),in the Qinling Mountains,central China.We investigated the abundance and distribution of food resources through sampling vegetation quadrats at different elevations and sampled anthropogenic activities using field surveys.Our results indicated that although there was no significant variation in food resources between low-(<1500 m)and middle-elevations(1500–2200 m),monkeys were found most often in areas above 1500 m,where there was less anthropogenic development(e.g.houses and roads);however,monkeys rarely ranged above 2200 m and had limited food availability at this altitude.There was limited human disturbance at this elevation.We suggest that both human activity and ecological constraints(i.e.food resources)have considerable effects on elevational use of R.roxellana in the Qinling Mountains.This study highlights the critical roles these factors can play in shaping the vertical distribution of high-altitude primates.This research provides useful insights for habitat-based conservation plans in which human disturbance management and habitat restoration should be prioritized. | Pengzhen HUANG Kun BIAN Zhipang HUANG Qi Li Derek WDUNN Gu FANG Jiahui LIU Mengyao WANG Xianfeng YANG Ruliang PAN Cunlao GAO Kaichuang SI Baoguo LI Xiaoguang QI | 2021 | Integrative Zoology2021，16，2： | 3 |
| 10 | Single-cell transcriptomic landscape of human blood cells显示文摘High throughput single-cell RNA-seq has been successfully implemented to dissect the cellular and molecular features underlying hematopoiesis.However,an elaborate and comprehensive transcriptome reference of the whole blood system is lacking.Here,we profiled the transcriptomes of 7551 human blood cells representing 32 immunophenotypic cell types,including hematopoietic stem cells,progenitors and mature blood cells derived from 21 healthy donors.With high sequencing depth and coverage,we constructed a single-cell transcriptional atlas of blood cells(ABC) on the basis of both protein-coding genes and long noncoding RNAs(lncRNAs),and showed a high consistence between them.Notably,putative lncRNAs and transcription factors regulating hematopoietic cell differentiation were identified.While common transcription factor regulatory networks were activated in neutrophils and monocytes,lymphoid cells dramatically changed their regulatory networks during differentiation.Furthermore,we showed a subset of nucleated erythrocytes actively expressing immune signals,suggesting the existence of erythroid precursors with immune functions.Finally,a web portal offering transcriptome browsing and blood cell type prediction has been established.Thus,our work provides a transcriptional map of human blood cells at single-cell resolution,thereby offering a comprehensive reference for the exploration of physiological and pathological hematopoiesis. | Xiaowei Xie Mengyao Liu Yawen Zhang Bingrui Wang Caiying Zhu Chenchen Wang Qing Li Yingying Huo Jiaojiao Guo Changlu Xu Linping Hu Aiming Pang Shihui Ma Una Wang Wenbin Cao Shulian Chen Qiuling Li Sudong Zhang Xueying Zhao Wen Zhou Hongbo Luo Guoguang Zheng Erlie Jiang Sizhou Feng Lixiang Chen Lihong Shi Hui Cheng Sha Hao Ping Zhu Tao Cheng | 2021 | National Science Review2021，8，3： | 3 |
| 11 | Magnetoresponsive nanozyme:magnetic stimulation on the nanozyme activity of iron oxide nanoparticles显示文摘The iron oxide nanoparticles(IONPs)that combine the nanozyme activity and magnetothermal properties have attracted significant interest for various biomedical applications.However,the effect of magnetic stimulation in fine-tuning the nanozyme activities remains unclear.Here,we have constructed a series of IONPs with different magneto-thermal conversion abilities,and systematically study the effect of magnetic field stimulation on the peroxidase(POD)activity of IONPs.The results show that POD activity is effectively amplified via an in situ alternating magnetic field(AMF)stimulation with no solution temperature rise,and the degree of activity enhancement is closely related to the magnetic heating ability of the IONPs,confirming the origin of activity enhancement arises from the local magnetothermal effect.As the first report to prove magnetothermal regulation on nanozyme activity and to shed lights on the underlying correlation between activity enhancement and the intrinsic specific absorption rate(SAR),this work is expected to provide important support for future design of new magnetoresponsive nanozymes in various practical applications. | Yuan He Xiaoyong Chen Ye Zhang Yanyun Wang Mengyao Cui Galong Li Xiaoli Liu Haiming Fan | 2022 | Science China(Life Sciences)2022，65，1： | 3 |
| 12 | High Individual Variability in Beak Stable Isotopes of Jumbo Squid off Peruvian Exclusive Economic Zone(EEZ) Waters in the Analysis of Migratory and Foraging Ecology显示文摘Stable isotopes(δ^(13)C and δ^(15)N) have been widely used to track cephalopod habitat, migration and trophic structure. In this study, we analyzed the δ^(13)C and δ^(15)N values in 245 Dosidicus gigas beaks collected during 2009–2010 and in 2013 off Peruvian Exclusive Economic Zone(EEZ) waters. High individual variation in beak stable isotopes was shown with values ranging from-19.4‰ to-15.8‰ for δ^(13)C and from 5.0‰ to 15.1‰ for δ^(15)N. A generalized additive model(GAM) showed that latitude, mantle length and distance to shelf break significantly described the isotope variation with deviance ranging from 16.6% in δ^(13)C to 36.3% in δ^(15)N. Large variability in beak δ^(13)C values for a given size and sampling station indicated that D. gigas off the Peruvian EEZ waters migrate in different ways when they occupy a large range of habitats for their ontogeny. Low baseline δ^(15)N values suggested that spatial changes in diet trophic level may be the main determinative factor in beak δ^(15)N variation. We conclude that high variability in beak δ^(15)N values for a given set of explanatory variables indicated that D. gigas is an opportunistic predator with highly diverse dietary habitats. This study further develops our knowledge of the life history of D. gigas in such a highly dynamic region. | LIU Bilin JIN Yue CHEN Xinjun LI Jianhua QIAN Weiguo LIU Na HUAN Mengyao | 2019 | Journal of Ocean University of China2019，18，1： | 3 |
| 13 | Effects of Integrated Soil-Crop System Management on Soil Organic Carbon Characteristics in a Primosol in Northeast China显示文摘A synchronous increase in crop productivity, nutrient use efficiency, and soil carbon(C) sequestration is important from the point of view of food security and environmental protection. In recent years, integrated soil-crop system management(ISSM), which uses crop models and advanced nutrient management to redesign cropping systems, has been successfully demonstrated to achieve both high crop productivity and high nutrient use efficiency in China, but the effects of ISSM on soil organic C(SOC) characteristics remain unknown. In this study, the effects of current farmers' practice(FP), high-yielding practice(HY), which maximizes yields without considering costs, and ISSM on the content and chemical composition of SOC were studied in a 4-year(2009–2013) field plot experiment with maize(Zea mays L.) monoculture in an Alluvic Primosol in Northeast China. The ISSM resulted in higher soil total organic C(TOC), water-soluble organic C, easily-oxidizable organic C, particulate organic C, and humic acid C compared with HY and FP in the region. The SOC contents in aggregate size fractions generally followed a similar pattern to TOC. Compared with FP,HY decreased the mean weight diameter, geometric mean diameter, percentage of > 0.25-mm water-stable aggregates, and the stability ratio of water-stable aggregates, and increased the structure-deterioration rate and index of unstable aggregates. The opposite trend was observed between ISSM and HY. Solid-state ^(13)C nuclear magnetic resonance spectra of bulk soil showed that ISSM had higher O-alkyl C and aliphatic C/aromatic C ratio, but lower aromatic C, carbonyl C, and alkyl C/O-alkyl C and hydrophobic C/hydrophilic C ratios than HY and FP. Our results suggest that ISSM improves the quantity and quality of SOC and has a positive effect on soil aggregation and aggregate stability. | ZHANG Jinjing CAO Zhiyuan FENG Guozhong LI Mengyao LI Cuilan GAO Qiang WANG Lichun | 2017 | Pedosphere2017，27，5： | 3 |

| 15 | The density of surface ligands regulates the luminescence of thiolated gold nanoclusters and their metal ion response显示文摘The fascinating luminescence properties of gold nanoclusters(AuNCs) have drawn considerable research interests,and been widely harnessed for a wide range of applications.However,a fundamental understanding towards ligand density’s role in the luminescence properties of these ultrasmall AuNCs remains unclear yet.In this communication,through systematic investigation of surface chemistries of glutathione-protected Au NCs(GSH-Au NCs) with diffe rent density of GSH as well as other thiolates,it is discovered that the density of surface ligands can significantly regulate the luminescence properties of AuNCs.Fluorescence lifetime spectroscopy and X-ray photoelectron spectroscopy showed that AuNCs with a higher density of electron-rich ligands facilitate their luminescence generation.Moreover,differences in the surface coverage of AuNCs can also affect their interactions with foreign species,as illustrated by significantly different fluorescence quenching capability of GSH-AuNCs with different ligand density towards Hg^(2+).This study provides new insight into the intriguing luminescence properties of metal NCs,which is hoped to stimulate further research on the design of metal NCs with strong luminescence and sensitive/specific responses for promising optoelectronic,sensing and imaging applications. | Jie Xu Juanmin Li Wencheng Zhong Mengyao Wen Gleb Sukhorukov Li Shang | 2021 | Chinese Chemical Letters2021，32，8： | 2 |
| 16 | Reliability and global sensitivity analysis for an airplane slat mechanism considering wear degradation显示文摘This paper focuses on the issue of reliability and global sensitivity analysis for an airplane slat mechanism considering the uncertainties in the wear process of mechanical components.First,the multi-body kinematic model of the slat mechanism is built in the ADAMS software.The geometrical sizes of the roller wheels after wear degradation are considered as input variables and the angle the slat should turn is considered as the output response.To accurately identify the influential roller wheels to the reliability and robustness of the slat mechanism,the failure probability based sensitivity and variance-based sensitivity indices are introduced.Comprehensive analysis of the results have shown that the reliability analysis and global sensitivity theory can help engineers find significant parts by their contributions,thus provide guidance for mechanical design and maintenance. | Changcong ZHOU Haodong ZHAO Qi CHANG Mengyao JI Chen LI | 2021 | Chinese Journal of Aeronautics2021，34，1： | 2 |
| 17 | Cobalt catalysts for Fischer–Tropsch synthesis: The effect of support,precipitant and pH value显示文摘In this report,Co-based catalysts supported on ZnO,Al_2O_3 and ZrO_2 as well as the ZrO_2 derived from different precipitants and different pH values were prepared by co-precipitation method.Their catalytic Fischer–Tropsch synthesis(FTS)performance was investigated in a fixed-bed reactor.The results revealed that Co catalyst supported on ZrO_2 exhibited better FTS catalytic performance than that supported on ZnO or Al_2O_3.For the Co/ZrO_2catalyst,different precipitants showed the following an activity order of NaOH>Na_2CO_3>NH_4OH,and the best pH value is 13.The catalysts were characterized by N_2adsorption–desorption,XRF,XRD,H_2-TPR,H_2-TPD and TEM.It was found that the main factor affecting the CO conversion of the catalyst was the amounts of low-temperature active adsorption sites.Moreover,the selectivity of C_5^+hydrocarbons had a positive relationship with the peak temperature of the weak hydrogen adsorption sites.The higher the peak temperature,the higher the C_5^+selectivity is. | zhenhua li mengyao si li xin renjie liu runxue liu jing lü | 2018 | Chinese Journal of Chemical Engineering2018，26，4： | 2 |

| 20 | A novel isoform of ATOH8 promotes the metastasis of breast cancer by regulating RhoC显示文摘Metastases are the main cause of cancer-related mortality in breast cancer.Although significant progress has been made in the field of tumor metastasis,the exact molecular mechanisms involved in tumor metastasis are still unclear.Here,we report that ATOH8-V1,a novel isoform of ATOH8,is highly expressed in breast cancer and is a negative prognostic indicator of survival for patients.Forced expression of ATOH8-V1 dramatically enhances,while silencing of ATOH8-V1 decreases the metastasis of breast cancer cell lines.Moreover,ATOH8-V1 directly binds to the RhoC promoter and stimulates the expression of RhoC,which in turn enhances the metastasis of breast cancer.Altogether,our data demonstrate that ATOH8-V1 is a novel pro-metastatic factor that enhances cancer metastasis,suggesting that AT0H8-V1 is a potential therapeutic target for treatment of metastatic cancers. | Mengyao Xu Shan Huang Xiaoli Dong Yanan Chen Miao Li Wen Shi Guanwen Wang Chongbiao Huang Qiong Wang Yanhua Liu Peiqing Sun Shuang Yang Rong Xiang Antao Chang | 2021 | Journal of Molecular Cell Biology2021，13，1： | 2 |
