| 1 | KIF2C:a novel link between Wnt/β-catenin and mTORCI signaling in the pathogenesis of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC)is the most common primary liver malignancy and is the fourth-leading cause of cancer-related deaths worldwide.HCC is refractory to many standard cancer treatments and the prognosis is often poor,highlighting a pressing need to identify biomarkers of aggressiveness and potential targets for future treatments.Kinesin family member 2C(KIF2C)is reported to be highly expressed in several human tumors.Nevertheless,the molecular mechanisms underlying the role of KIF2C in tumor development and progression have not been investigated.In this study,we found that KIF2C expression was significantly upregulated in HCC,and that KIF2C up-regulation was associated with a poor prognosis.Utilizing both gain and loss of function assays,we showed that KIF2C promoted HCC cell proliferation,migration,invasion,and metastasis both in vitro and in vivo.Mechanistically,we identified TBC1D7 as a binding partner of KIF2C,and this interaction disrupts the formation of the TSC complex,resulting in the enhancement of mammalian target of rapamycin complexl(mTORCI)signal transduction.Additionally,we found that KIF2C is a direct target of the Wnt/β-catenin pathway,and acts as a key factor in mediating the crosstalk between Wnt/β-catenin and mTORCI signaling.Thus,the results of our study establish a link between Wnt/β-catenin and mTORCI signaling,which highlights the potential of KIF2C as a therapeutic target for the treatment of HCC. | Shi Wei Miaomiao Dai Chi Zhang Kai Teng Fengwei Wang Hongbo Li Weipeng Sun Zihao Feng Tiebang Kang Xinyuan Guan Ruihua Xu Muyan Cai Dan Xie | 2021 | Protein & Cell2021，12，10： | 8 |
| 2 | Novel Ag nanocrystals based dental resin composites with enhanced mechanical and antibacterial properties显示文摘The aim of this work was to investigate the effect of trace addition of oleic acid coated Ag nanocrystals(Ag NCs) on mechanical and antibacterial properties of dental resin composites.Composites(70 wt%of silica loading) with 25 ppm,50 ppm,75 ppm and 100 ppm(wt) Ag NCs were prepared and the composite without Ag NCs served as a control.The experimental results showed that the addition of Ag NCs significantly improved the strength and modulus of the resin composite without compromising the shade.For the composite with 50 ppm Ag NCs,fiexural strength(140.3 MPa),modulus(13.2 GPa)and compressive strength(347.2 MPa) were increased by 4.1%,22.2%,13.3%,respectively,compared with the control.The antibacterial test demonstrated that trace Ag NCs provided the resin composites with an antibacterial effect.Such strong and antibacterial dental resin composites might be advantageous to prevent secondary caries and be potential for future clinical applications. | Fengwei Liu Ruili Wang Yuyuan Shi Xiaoze Jiang Bin Sun Meifang Zhu | 2013 | Progress in Natural Science:Materials International2013，23，6： | 5 |
| 3 | 120 mm Single-crystalline perovskite and wafers: towards viable applications显示文摘As the large single-crystalline silicon wafers have revolutionized many industries including electronics and solar cells, it is envisioned that the availability of large single-crystalline perovskite crystals and wafers will revolutionize its broad applications in photovoltaics, optoelectronics, lasers, photodetectors, light emitting diodes(LEDs), etc. Here we report a method to grow large single-crystalline perovskites including single-halide crystals: CH3NH3PbX3(X=I, Br, Cl), and dual-halide ones:CH3NH3Pb(ClxBr1.x)3 and CH3NH3Pb(BrxI1.x)3, with the largest crystal being 120 mm in length. Meanwhile, we have advanced a process to slice the large perovskite crystals into thin wafers. It is found that the wafers exhibit remarkable features:(1)its trap-state density is a million times smaller than that in the microcrystalline perovskite thin films(MPTF);(2) its carrier mobility is 410 times higher than its most popular organic counterpart P3HT;(3) its optical absorption is expanded to as high as910 nm comparing to 797 nm for the MPTF;(4) while MPTF decomposes at 150 °C, the wafer is stable at high temperature up to270 °C;(5) when exposed to high humidity(75% RH), MPTF decomposes in 5 h while the wafer shows no change for overnight;(6) its photocurrent response is 250 times higher than its MPTF counterpart. A few electronic devices have been fabricated using the crystalline wafers. Among them, the Hall test gives low carrier concentration with high mobility. The trap-state density is measured much lower than common semiconductors. Moreover, the large SC-wafer is found particularly useful for mass production of integrated circuits. By adjusting the halide composition, both the optical absorption and the light emission can be fine-tuned across the entire visible spectrum from 400 nm to 800 nm. It is envisioned that a range of visible lasers and LEDs may be developed using the dual-halide perovskites. With fewer trap states, high mobility, broader absorption, and humidity resistance, it is expected that solar cells with high stable efficiency maybe attainable using the crystalline wafers. | Yucheng Liu Xiaodong Ren Jing Zhang Zhou Yang Dong Yang Fengyang Yu Jiankun Sun Changming Zhao Zhun Yao Bo Wang Qingbo Wei Fengwei Xiao Haibo Fan Hao Deng Liangping Deng Shengzhong (Frank) Liu | 2017 | Science China Chemistry2017，60，10： | 5 |

| 6 | Application of Screw Press Filter for Oily Sludge Dewatering显示文摘In order to find suitable oily sludge treatment equipment for a produced water treatment station of an oilfield in Iraq,the widely used mechanical dewatering equipments overseas including plate and frame filter,belt press filter,centrifugal filter and screw press filter were compared and analyzed,and the application situation of screw press filter was investigated at site. The site survey showed that,screw press filter was an integrated equipment combined with functions of concentrating and dewatering,which was characterized by low water content of filter cake,small occupied area,easy to separate,no blocking and can realize self-cleaning,which is suitable to low concentration sludge. Screw press filter can simplify oily sludge treatment process,and save engineering construction and operation cost,which is a better choice for oily sludge dewatering. The design of screw press filter adopted in the produced water treatment station of an oilfield in Iraq was introduced here. | Sun Xueyi Zhao Fengwei Li Jinlin Yuan Guoqing | 2017 | Meteorological and Environmental Research2017，8，2： | 1 |

| 10 | Gene amplification-driven RNA methyltransferase KIAA1429 promotes tumorigenesis by regulating BTG2 via m6A-YTHDF2-dependent in lung adenocarcinoma显示文摘Background:Epigenetic alterations have been shown to contribute immensely to human carcinogenesis.Dynamic and reversible N6-methyladenosine(m6A)RNA modification regulates gene expression and cell fate.However,the reasons for activation of KIAA1429(also known as VIRMA,an RNA methyltransferase)and its underlying mechanism in lung adenocarcinoma(LUAD)remain largely unexplored.In this study,we aimed to clarify the oncogenic role of KIAA1429 in the tumorigenesis of LUAD.Methods:Whole-genome sequencing and transcriptome sequencing of LUAD data were used to analyze the gene amplification of RNA methyltransferase.The in vitro and in vivo functions of KIAA1429 were investigated.Transcriptome sequencing,methylated RNA immunoprecipitation sequencing(MeRIP-seq),m6A dot blot assays and RNA immunoprecipitation(RIP)were performed to confirm the modified gene mediated by KIAA1429.RNA stability assays were used to detect the half-life of the target gene.Results:Copy number amplification drove higher expression of KIAA1429 in LUAD,whichwas correlatedwith poor overall survival.Manipulating the expression of KIAA1429 could regulate the proliferation and metastasis of LUAD.Mechanistically,the target genes of KIAA1429-mediated m6A modification were confirmed by transcriptome sequencing and MeRIP-seq assays.We also revealed that KIAA1429 could regulate BTG2 expression in an m6A-dependent manner.Knockdown of KIAA1429 significantly decreased the m6A levels of BTG2 mRNA,leading to enhanced YTH m6A RNA binding protein 2(YTHDF2,the m6A“reader”)-dependent BTG2 mRNA stability and promoted the expression of BTG2;thus,participating in the tumorigenesis of LUAD.Conclusions:Our data revealed the activation mechanism and important role of KIAA1429 in LUAD tumorigenesis,which may provide a novel view on the targeted molecular therapy of LUAD. | Chang Zhang Qi Sun Xu Zhang Na Qin Zhening Pu Yayun Gu Caiwang Yan Meng Zhu Juncheng Dai ChengWang Ni Li Guangfu Jin Hongxia Ma Zhibin Hu Erbao Zhang Fengwei Tan Hongbing Shen | 2022 | Cancer Communications2022，42，7： | 1 |

| 12 | Repurposing organic semiconducting nanomaterials to accelerate clinical translation of NIR-II fluorescence imaging显示文摘Optical imaging possesses important implications for early disease diagnosis,timely disease treatment,and basic medical as well as biological research.Compared with the traditionary near-infrared(NIR-I)window(650-950 nm)optical imaging,the emerging second near-infrared(NIR-II)window optical imaging technology owns the great superiorities of non-invasiveness,nonionizing radiation,and real-time dynamic imaging with the low biological interference,can significantly improve the tissue penetration depth and detection sensitivity,thus expecting to achieve accurate and precise diagnosis of major diseases.Inspired by the conspicuous superiorities,an increasing number of versatile NIR-II fluorophores have been legitimately designed and engineered for precisely deep-tissue mapping-mediated theranostics of life-threatening diseases.Organic semiconducting nanomaterials(OSNs)are derived from organic conjugated molecules withπ-electron delocalized skeletons,which show greatly preponderant prospects in the biomedicine field due to the excellent photoelectric property,tunable energy bands,and fine biocompatibility.In this review,the superiorities of NIR-II fluorescence imaging using OSNs for brilliant visualization various of diseases,including tongue cancer,ovarian cancer,osteosarcoma,bacteria or pathogens infection,kidney dysfunction,rheumatoid arthritis,liver injury,and cerebrovascular function,are emphatically summarized.Finally,the reasonable prospects and persistent efforts for repurposing OSNs to facilitate the clinical translation of NIR-II fluorescence phototheranostics are outlined. | Xiaoming Hu Fengwei Sun Caijun Zhu Zhen Yang Wei Huang | 2023 | Nano Research2023，16，4： | 0 |
| 13 | Polymerization-Induced Self-Assembly for Efficient Fabrication of Biomedical Nanoplatforms显示文摘Amphiphilic copolymers can self-assemble into nano-objects in aqueous solution.However,the selfassembly process is usually performed in a diluted solution(<1 wt%),which greatly limits scale-up production and further biomedical applications.With recent development of controlled polymerization techniques,polymerization-induced self-assembly(PISA)has emerged as an efficient approach for facile fabrication of nano-sized structures with a high concentration as high as 50 wt%.In this review,after the introduction,various polymerization method-mediated PISAs that include nitroxide-mediated polymerization-mediated PISA(NMP-PISA),reversible addition-fragmentation chain transfer polymerizationmediated PISA(RAFT-PISA),atom transfer radical polymerization-mediated PISA(ATRP-PISA),and ringopening polymerization-mediated PISA(ROP-PISA)are discussed carefully.Afterward,recent biomedical applications of PISA are illustrated from the following aspects,i.e.,bioimaging,disease treatment,biocatalysis,and antimicrobial.In the end,current achievements and future perspectives of PISA are given.It is envisioned that PISA strategy can bring great chance for future design and construction of functional nano-vehicles. | Xiaopeng Zhao Changrui Sun Fei Xiong Ting Wang Sheng Li Fengwei Huo Xikuang Yao | 2023 | Research2023，，4： | 0 |

| 15 | Incorporating metal nanoparticles in porous materials via selective heating effect using microwave显示文摘Metal nanoparticle@porous material composites have attracted increasing attention due to their excellent synergistic catalytic performance.However,it is a challenge to introduce metal nanoparticles into cavities of porous materials without agglomeration on the exterior.Despite the progress achieved,a universal approach that can integrate different kinds of metal nanoparticles and porous materials is still highly desirable.Here we report a facile and general approach to fabricating metal nanoparticle@porous materials by microwave-triggered selective heating.The microwave can pass through the non-polar solvent and act on the polar solvent in the porous materials,causing the polar solvent to be heated,vaporized,and away from the pores of porous materials.The local void produced by the escape of polar solvent facilitates non-polar solvent containing metallic precursor to be dragged into the narrow pores,followed by further reduction,resulting in the complete encapsulation of nanoparticles.A series of metal nanoparticles@porous materials,ranging from metal-organic frameworks(MOFs)to zeolites,are successfully prepared by this method and show excellent size selectivity in catalytic reactions. | Yingyu Zhou Jiacheng Liu Fuyuan Sun Junchen Ouyang Ruifa Su Fanchen Meng Yongqi Luo Cheng Xu Weina Zhang Suoying Zhang Fengwei Huo | 2024 | Nano Research2024，17，4： | 0 |
| 16 | Development of MEMS directed evolution strategy for multiplied throughput and convergent evolution of cytochrome P450 enzymes显示文摘Directed evolution(DE)inspired by natural evolution(NE)has been achieving tremendous successes in protein/enzyme engineering.However,the conventional'one-protein-for-one-task'DE cannot match the'multi-proteins-for-multi-tasks'NE in terms of screening throughput and efficiency,thus often failing to meet the fast-growing demands for biocatalysts with desired properties.In this study,we design a novel'multi-enzymes-for-multi-substrates'(MEMS)DE model and establish the proof-ofconcept by running a NE-mimicking and higher-throughput screening on the basis of'two-P450 s-against-seven-substrates'(2P×7S)in one pot.With the multiplied throughput and improved hit rate,we witness a series of convergent evolution events of the two archetypal cytochrome P450 enzymes(P450 BM3 and P450 cam)in laboratory.It is anticipated that the new strategy of MEMS DE will find broader application for a larger repertoire of enzymes in the future.Furthermore,structural and substrate docking analysis of the two functionally convergent P450 variants provide important insights into how distinct P450 active-sites can reach a common catalytic goal. | Li Ma Fengwei Li Xingwang Zhang Hui Chen Qian Huang Jing Su Xiaohui Liu Tianjian Sun Bo Fang Kun Liu Dandan Tang Dalei Wu Wei Zhang Lei Du Shengying Li | 2022 | Science China(Life Sciences)2022，65，3： | 0 |
| 17 | Strenuous exercise-tolerance stretchable dry electrodes for continuous multi-channel electrophysiological monitoring显示文摘Electrophysiological monitoring under strenuous exercise by using stretchable dry electrodes is vital for healthcare monitoring,prosthetic control,human−machine interfaces and other biomedical applications.However,the existing dry electrodes are not applicable to the strenuous exercise situation that always involves both fast moving and profuse sweating.Herein,we present a nano-thick porous stretchable dry electrode system with high stretchability and water permeability.The system attaches conformably to the skin and stretches with it under Van der Waals forces even at sweating conditions,allowing the detection of electromyogram when moving with an acceleration of 10 g at a sweating rate of 2.8 mg cm^(−2) min^(−1).It is also capable of acquiring electrocardiogram and electroencephalogram signals.The strategy proposed would enable the biomedical studies and related applications with the requirement of stably recording electrophysiological signals under strenuous exercise scenarios. | Ruijie Xie Qingsong Li Lijun Teng Zhengshuai Cao Fei Han Qiong Tian Jing Sun Yang Zhao Mei Yu Dianpeng Qi Peizhi Guo Guanglin Li Fengwei Huo Zhiyuan Liu | 2022 | npj Flexible Electronics2022，6，1： | 0 |
