2Gain-of-function mutant p53 in cancer progression and therapy显示文摘p53 is a key tumor suppressor,and loss of p53 function is frequently a prerequisite for cancer development.The p53 gene is the most frequently mutated gene in human cancers;p53 mutations occur in>50%of all human cancers and in almost every type of human cancers.Most of p53 mutations in cancers are missense mutations,which produce the full-length mutant p53(mutp53)protein with only one amino acid difference from wild-type p53 protein.In addition to loss of the tumor-suppressive function of wild-type p53,many mutp53 proteins acquire new oncogenic activities independently of wild-type p53 to promote cancer progression,termed gain-of-function(GOF).Mutp53 protein often accumulates to very high levels in cancer cells,which is critical for its GOF.Given the high mutation frequency of the p53 gene and the GOF activities of mutp53 in cancer,therapies targeting mutp53 have attracted great interest.Further understanding the mechanisms underlying mutp53 protein accumulation and GOF will help develop effective therapies treating human cancers containing mutp53.In this review,we summarize the recent advances in the studies on mutp53 regulation and GOF as well as therapies targeting mutp53 in human cancers.Cen Zhang Juan Liu Dandan Xu Tianliang Zhang Wenwei Hu Zhaohui Feng 2020Journal of Molecular Cell Biology2020,12,9:18

4Elevated G6PD expression contributes to migration and invasion of hepatocellular carcinoma cells by inducing epithelial-mesenchymal transition显示文摘改变的新陈代谢是癌症房间的特点之一。戊糖磷酸盐小径(PPP ) 是细胞的新陈代谢的一个基本部件。Glucose-6-phosphate 脱氢酶(G6PD ) , PPP 的限制率的酶,在许多癌症被提高并且由通过 PPP 生产 ribose-5-phosphate 和 NADPH 贡献肿瘤生长。然而,在 hepatocellular 的 G6PD 的角色癌(HCC ) 转移和在 HCC 前进和预后的 G6PD 的临床的意义一直不是很好坚定的。在这研究,由从 HCC 病人和 HCC 房间线调查织物样品,我们发现那提高的 G6PD 表情显著地与 HCC 转移和差的预后被联系 HCC,和那 G6PD 击倒在 vitro 禁止 HCC 房间线的增长,移植和侵略。进一步的研究表明 G6PD 由通过信号变换器的激活和抄写 3 的使活跃之物(STAT3 ) 导致上皮间充质的转变贡献 HCC 移植和 hepatocellular 癌房间的侵略小径。我们的调查结果建议那指向的 G6PD 能为转移干预开创可能性并且为 HCC 改进病人结果。Ming Lu Lu Lu Qiongzhu Dong Guangyang Yu Jinhong Chen Lunxiu Qin Lianxin Wang Wenwei Zhu Huliang Jia 2018Acta Biochimica et Biophysica Sinica2018,50,4:10
5Sintilimab versus docetaxel as second-line treatment in advanced or metastatic squamous non-small-cell lung cancer:an open-label,randomized controlled phase 3 trial(ORIENT-3)显示文摘Background:Treatment options for Chinese patients with locally advanced or metastatic squamous-cell non-small-cell lung cancer(sqNSCLC)after failure of first-line chemotherapy are limited.This study(ORIENT-3)aimed to evaluate the efficacy and safety of sintilimab versus docetaxel as second-line treatment in patients with locally advanced or metastatic sqNSCLC.Methods:ORIENT-3 was an open-label,multicenter,randomized controlled phase 3 trial that recruited patients with stage IIIB/IIIC/IV sqNSCLC after failure with first-line platinum-based chemotherapy.Patients were randomized in a 1:1 ratio to receive either 200 mg of sintilimab or 75 mg/m^(2) of docetaxel intravenously every 3 weeks,stratified by the Eastern Cooperative Oncology Group performance status.The primary endpoint was overall survival(OS)in the full analysis set(FAS).Secondary endpoints included progression-free survival(PFS),objective response rate(ORR),disease control rate(DCR),duration of response(DoR)and safety.Results:Between August 25,2017,and November 7,2018,290 patients were randomized.For FAS,10 patients fromthe docetaxel armwere excluded.Themedian OS was 11.79(n=145;95%confidence interval[CI],10.28-15.57)months with sintilimab versus 8.25(n=135;95%CI,6.47-9.82)months with docetaxel(hazard ratio[HR]:0.74;95%CI,0.56-0.96;P=0.025).Sintilimab treatment significantly prolonged PFS(median 4.30 vs.2.79 months;HR:0.52;95%CI,0.39-0.68;P<0.001)and showed higher ORR(25.50%vs.2.20%,P<0.001)and DCR(65.50%vs.37.80%,P<0.001)than the docetaxel arm.The median DoRwas 12.45(95%CI,4.86-25.33)months in the sintilimab arm and 4.14(95%CI,1.41-7.23)months in the docetaxel arm(P=0.045).Treatment-related adverse events of grade≥3were reported in 26(18.1%)patients in the sintilimab arm and 47(36.2%)patients in the docetaxel arm.Exploratory biomarker analysis showed potential predictive values of expression levels of two transcription factors,including OVOL2(HR:0.35;P<0.001)and CTCF(HR:3.50;P<0.001),for sintilimab treatment.Conclusions:Compared with docetaxel,sintilimab significantly improved the OS,PFS,and ORR of Chinese patients with previously treated locally advanced or metastatic sqNSCLC.Yuankai Shi Lin Wu Xinmin Yu Puyuan Xing Yan Wang Jianying Zhou Airong Wang Jianhua Shi Yi Hu Ziping Wang Guangyu An Yong Fang Sanyuan Sun Caicun Zhou Changli Wang Feng Ye Xingya Li Junye Wang Mengzhao Wang Yunpeng Liu Yanqiu Zhao Ying Yuan Jifeng Feng Zhendong Chen Jindong Shi Tao Sun Gang Wu Yongqian Shu Qisen Guo Yi Zhang Yong Song Shucai Zhang Yuan Chen Wei Li Hongrui Niu Wenwei Hu Lijun Wang Jianan Huang Yang Zhang Ying Cheng Zhengdong Wu Bo Peng Jiya Sun Christoph Mancao Yanqi Wang Luyao Sun 2022Cancer Communications2022,42,12:8
6Responses of Patients with Disorders of Consciousness to Habit Stimulation:A Quantitative EEG Study显示文摘Whether habit stimulation is effective in DOC patient arousal has not been reported. In this paper, we analyzed the responses of DOC patients to habit stimulation. Nineteen DOC patients with alcohol consumption or smoking habits were recruited and 64-channel EEG signals were acquired both at the resting state and at three stimulation states. Wavelet transformation and nonlinear dynamics were used to extract the features of EEG signals and four brain lobes were selected to investigate the degree of EEG response to habit stimulation. Results showed that the highest degree of EEG response was from the callname stimulation, followed by habit and music stimulations. Significant differences in EEG wavelet energy and response coefficient were found both between habit and music stimulation, and between habit and call-name stimulation. These findings prove that habit stimulation induces relatively more intense EEG responses in DOC patients than music stimulation, suggesting that it may be a relevant additional method for eliciting patient arousal.Jingqi Li Jiamin Shen Shiqin Liu Maelig Chauvel Wenwei Yang Jian Mei Ling Lei Li Wu Jian Gao Yong Yang 2018Neuroscience Bulletin2018,34,4:8
7Allogeneic Vγ9Vδ2 T-cell immunotherapy exhibits promising clinical safety and prolongs the survival of patients with late-stage lung or liver cancer显示文摘Vγ9Vδ2 T cells are promising candidates for cellular tumor immunotherapy.Due to their HLA-independent mode of action,allogeneic Vγ9Vδ2 T cells can be considered for clinical application.To apply allogeneic Vγ9Vδ2 T cells in adoptive immunotherapy,the methodology used to obtain adequate cell numbers with optimal effector function in vitro needs to be optimized,and clinical safety and efficacy also need to be proven.Therefore,we developed a novel formula to improve the expansion of peripheralγδT cells from healthy donors.Then,we used a humanized mouse model to validate the therapeutic efficacy of expandedγδT cells in vivo;furthermore,the expandedγδT cells were adoptively transferred into late-stage liver and lung cancer patients.We found that the expanded cells possessed significantly improved immune effector functions,including proliferation,differentiation,and cancer cell killing,both in vitro and in the humanized mouse model.Furthermore,a phase I clinical trial in 132 late-stage cancer patients with a total of 414 cell infusions unequivocally validated the clinical safety of allogeneic Vγ9Vδ2 T cells.Among these 132 patients,8 liver cancer patients and 10 lung cancer patients who received≥5 cell infusions showed greatly prolonged survival,which preliminarily verified the efficacy of allogeneic Vγ9Vδ2 T-cell therapy.Our clinical studies underscore the safety and efficacy of allogeneic Vγ9Vδ2 T-cell immunotherapy,which will inspire further clinical investigations and eventually benefit cancer patients.Yan Xu Zheng Xiang Mohammed Alnaggar Léonce Kouakanou Jiawei Li Junyi He Jiashuang Yang Yi Hu Yan Chen Li Lin Jianlei Hao Jingxia Li Jibing Chen Man Li Qingling Wu Christian Peters Qinghua Zhou Jianshuang Li Yingqing Liang Xiaohua Wang Baohui Han Meili Ma Dieter Kabelitz Kecheng Xu Wenwei Tu Yangzhe Wu Zhinan Yin 2021Cellular & Molecular Immunology2021,18,2:8
8Structural design inspired by beetle elytra and its mechanical properties显示文摘On the basis of the microstructure of the cross-section of a beetle's elytra,three bio-inspired lightweight structures were designed and built from acrylonitrile butadiene styrene plastic with a three-dimensional printer.The mechanical properties of three lightweight structures were analyzed and compared employing the finite element method,and quasi-static compression experiments and a three-point bending test on the structure samples were carried out using an electronic universal testing machine to verify the effectiveness of the finite element method.The results show that all three bio-structures were lightweight and had excellent mechanical properties.In particular,the bio-structure with spherical holes and hollow columns perpendicular to the top and bottom surfaces best imitated the microstructure of the cross-section of the Cybister elytra and had the greatest specific strength/stiffness in compression and bending.Finally,a preliminary optimization design was obtained for this bio-structure to further improve its specific strength and specific stiffness to 31.82 kN m/kg and 108.73 kN m 2 /kg respectively.GUO Ce SONG WenWei DAI ZhenDong 2012Chinese Science Bulletin2012,57,8:8
9Advanced chemical strategies for lithium-sulfur batteries: A review显示文摘Lithium-sulfur(Li-S) battery has been considered as one of the most promising rechargeable batteries among various energy storage devices owing to the attractive ultrahigh theoretical capacity and low cost. However, the performance of Li-S batteries is still far from theoretical prediction because of the inherent insulation of sulfur, shuttling of soluble polysulfides, swelling of cathode volume and the formation of lithium dendrites. Significant efforts have been made to trap polysulfides via physical strategies using carbon based materials, but the interactions between polysulfides and carbon are so weak that the device performance is limited. Chemical strategies provide the relatively complemented routes for improving the batteries' electrochemical properties by introducing strong interactions between functional groups and lithium polysulfides. Therefore, this review mainly discusses the recent advances in chemical absorption for improving the performance of Li-S batteries by introducing functional groups(oxygen, nitrogen, and boron, etc.) and chemical additives(metal, polymers, etc.) to the carbon structures, and how these foreign guests immobilize the dissolved polysulfides.Xiaojing Fan Wenwei Sun Fancheng Meng Aiming Xing Jiehua Liu 2018Green Energy & Environment2018,3,1:7

11Response surface modeling-based source contribution analysis and VOC emission control policy assessment in a typical ozone-polluted urban Shunde,China显示文摘To develop a sound ozone(O_3) pollution control strategy,it is important to well understand and characterize the source contribution due to the complex chemical and physical formation processes of O_3.Using the 'Shunde' city as a pilot summer case study,we apply an innovative response surface modeling(RSM) methodology based on the Community Multi-Scale Air Quality(CMAQ) modeling simulations to identify the O_3 regime and provide dynamic analysis of the precursor contributions to effectively assess the O_3 impacts of volatile organic compound(VOC) control strategy.Our results show that Shunde is a typical VOC-limited urban O_3 polluted city.The 'Jiangmen' city,as the main upper wind area during July 2014,its VOCs and nitrogen oxides(NO_x) emissions make up the largest contribution(9.06%).On the contrary,the contribution from local(Shunde) emission is lowest(6.35%) among the seven neighbor regions.The local VOCs industrial source emission has the largest contribution comparing to other precursor emission sectors in Shunde.The results of dynamic source contribution analysis further show that the local NO_x control could slightly increase the ground O_3 under low(10.00%) and medium(40.00%)reduction ratios,while it could start to turn positive to decrease ground O_3 under the high NO_x abatement ratio(75.00%).The real-time assessment of O_3 impacts from VOCs control strategies in Pearl River Delta(PRD) shows that the joint regional VOCs emission control policy will effectively reduce the ground O_3 concentration in Shunde.Zhiqiang You Yun Zhu Carey Jang Shuxiao Wang Jian Gao Che-Jen Lin Minhui Li Zhenghua Zhu Hao Wei Wenwei Yang 2017Journal of Environmental Sciences2017,29,1:7
12Uncompromised NK cell activation is essential for virus-specific CTL activity during acute influenza virus infection显示文摘Natural killer (NK) cells are indispensable components of both the innate and adaptive immune response. However,their precise roles in the cross-talk between innate and adaptive immunity during influenza virus infection remaincontroversial. By comparing NK cell dynamics and activity under a sub-lethal dose and high dose of influenza virusinfection, we showed that influenza virus PR8 directly infected NK cells during natural infection, which wasconsistent with our previous findings obtained from an in vitro investigation of human NK cells. The impairments incytotoxicity and IFN-γ production by spleen NK cells following high-dose infection were accompanied by decreasedvirus-specific killing mediated by cytotoxic T lymphocytes (CTLs). Importantly, the weakened CTL activity could bereversed by adoptive transfer of spleen NK cells harvested from low-dose-infected mice but not healthy donors.Taken together, our data provide direct evidence supporting the contribution of NK cells to antiviral T-cellresponses. This study also indicates that a novel NK-targeted immune evasion strategy is used by influenza virusto shrink both innate and adaptive immune responses.Yuan Liu Jian Zheng Yinping Liu Liyan Wen Lei Huang Zheng Xiang Kwok-Tai Lam Aizhen Lv Huawei Mao Yu-Lung Lau Wenwei Tu 2018Cellular & Molecular Immunology2018,15,9:6
13Numerical study on the characteristics of flow field and wave propagation near submerged breakwater on slope显示文摘In this study,characteristics of flow field and wave propagation near submerged breakwater on a sloping bed are investigated with numerical model. The governing equations of the vertical twodimensional model are Reynolds Averaged Navier Stokes equations. The Reynolds stress terms are closed by a nonlinear k ε turbulence transportation model. The free surface is traced through the PILC-VOF method. The proposed numerical model is verified with experimental results. The numerical result shows that the wave profile may become more asymmetrical when wave propa-gates over breakwater. When wave crest propagates over breakwater,the anticlockwise vortex may generate. On the contrary,when wave hollow propagates over breakwater,the clockwise vortex may generate. Meanwhile,the influenced zone of vortex created by wave crest is larger than that created by wave hollow. All the maximum values of the turbulent kinetic energy,turbulent dissi-pation and eddy viscosity occur on the top of breakwater. Both the turbulent dissipation and eddy viscosity increase as the turbulent kinetic energy increases. Wave energy may rapidly decrease near the breakwater because turbulent dissipation increases and energy in lower harmonics is transferred into higher harmonics.CHEN Jie JIANG Changbo HU Shixiong HUANG Wenwei 2010Acta Oceanologica Sinica2010,29,1:6

15Dominant Gene cplsr1 Corresponding to Premature Leaf Senescence Resistance in Cotton (Gossypium hirsutum L.)显示文摘Cotton (Gossypium hirsutum L.) premature leaf senescence-resistant inbred XLZ33 and senescence-susceptible inbred lines XLZ13 were selected and crossed to produce F1, F1-reciprocal, F2 and BC1 generations for evaluation of leaf senescence process and inheritance. The results showed that leaf senescence processes for XLZ13 and XLZ33 were obviously different and leaf senescence traits could be distinguished between the two parents at particular periods of cotton growth. Inheritance anlysis for the cotton premature leaf senescence resistant trait further showed that the segregation in the F2 fit a 3:1 ratio inheritance pattern, with resistance being dominant. The backcross of F1 to the susceptible parent produced a 1:1 ratio, confirming that cotton premature leaf senescence resistant trait was from a single gene. The single dominant gene controlling cotton premature leaf senescence resistance in XLZ33 was named as cotton premature leaf senescence resistance 1, with the symbol cplsr1.Jingqing Zhao Tengfei Jiang Zhi Liu Wenwei Zhang Guiliang Jian Fanfljun Qi 2012Journal of Integrative Plant Biology2012,54,8:6
16Big Roles of Small Kinases:The Complex Functions of Receptor-Like Cytoplasmic Kinases in Plant Immunity and Development显示文摘Plants have evolved a large number of receptor-like cytoplasmic kinases(RLCKs)that often functionally and physically associate with receptor-like kinases(RLKs)to modulate plant growth,development and immune responses.Without any apparent extracellular domain,RLCKs relay intracellular signaling often via RLK complex-mediated transphosphorylation events.Recent advances have suggested essential roles of diverse RLCKs in concert with RLKs in regulating various cellular and physiological responses.We summarize here the complex roles of RLCKs in mediating plant immune responses and growth regulation,and discuss specifc and overlapping functions of RLCKs in transducing diverse signaling pathways.Wenwei Lin Xiyu Ma Libo Shan Ping He 2013Journal of Integrative Plant Biology2013,55,12:6
17Ordovician integrative stratigraphy and timescale of China显示文摘In this chapter, starting with a brief review of the research history and current status in the studies of the Ordovician chronostratigraphy in China, the subdivision of the Ordovician System, definition and recognition of its series and stage boundaries, and possible stratigraphic gaps are discussed in details in order to establish a multidisciplinary stratigraphic correlation through an integrated approach including lithostratigraphy, biostratigraphy, radiometric dating, chemostratigraphy and magnetostratigraphy. Being internationally accepted, the Ordovician System is now subdivided into three series and seven stages, in ascending order, Lower(Tremadocian, Floian), Middle(Dapingian, Darriwilian) and Upper series(Sandbian, Katian,Hirnantian). Three of the seven 'Golden Spikes' defining the bases of the Ordovician stages, which were established in 1997–2007, are located in China. As a regionally applied chronostratigraphy, the Ordovician System was subdivided in China into Lower(Xinchangian, Yiyangian), Middle(Dapingian, Darriwilian) and Upper series(Neichiashanian, Chientangkiangian,Hirnantian). This scheme agrees largely with the standard international classification, which can actually be directly applied to China, except for some special circumstances where the Neichiashanian and Chientangkiangian stages of the Upper Ordovician are used. Based on the new studies in recent years and distinctions and differences recognized in the development of the Ordovician System in the constituent terranes of China, a new framework for correlation among the major Chinese palaeoplates or terranes, e.g. South China, North China(including Tarim and Qaidam) and Xizang(Tibet)-western Yunnan, has been established. However, it has been recognized herein that uncertainties still remain on defining the base of the Tremadocian,Dapingian and Katian, and on the correlation between different mega-facies. More specifically, for the Tremadocian, the precise correlation of its base will depend on the better-defined conodont taxonomy, while for the Dapingian and Katian, on the correlation between different mega-facies. It is worthwhile to note that the chemostratigraphic studies of the Ordovician System in China produced the carbonate δ13 C curves for the Darriwilian(Middle Ordovician) and Katian(Upper Ordovician), which show significant differences from the composite global curve. Record of the Ordovician isotopic dating is relatively rare in China, with only three reliable ages from zircons that are all from the upper Katian to Hirnantian of the Upper Ordovician.Abundant bentonite beds in the Upper Ordovician of South China will also provide unique opportunities to advance the isotopic dating and related researches. Studies on the Ordovician magnetostratigraphy need to be significantly enhanced in China, as currently all the available results are restricted to the Lower Ordovician of North China, although they can be correlated with those known from other parts of the world. The analysis of the durational unevenness of the seven stages in the Ordovician supports the possibility to further subdivide the long-durational Tremadocian, Darriwilian and Katian stages, each into two substages.Yuandong ZHANG Renbin ZHAN Yongyi ZHEN Zhihao WANG Wenwei YUAN Xiang FANG Xuan MA Junpeng ZHANG 2019Science China Earth Sciences2019,62,1:6
18Preparation of nano-sized cerium and titanium pyrophosphates via solid-state reaction at room temperature显示文摘Nano-sized cerium-titanium pyrophosphates Ce1-xTixP2O7 (with x = 0, 0.2, 0.5, 0.7, 0.9, and 1.0) were obtained by grinding a mixture of Ce(SO4)2·4H2O, Ti(SO4)2, and Na4P2O7·10H2O in the presence of surfactant PEG-400 at room temperature, washing the mixture with water to remove soluble inorganic salts, and drying at 100°C. The products and their calcined samples were characterized using ultraviolet-visible spectroscopy (UV-vis), thermogravimetry and differential thermal analyses (TG/DTA), X-ray powder diffraction (XRD), and transmission electron microscopy (TEM). The results show that nano-sized Ce1-xTixP2O7 behave as an excellent UV-shielding material. Thereinto, the CeP2O7 has the most excellent UV-shielding effect, and the amorphous state of Ce0.8Ti0.2P2O7 can keep at a higher temperature than CeP2O7. Therefore, the stabilization of the amorphous state of the cerium pyrophosphates was carried out by doping titanium. This stabilization is a significant improvement, which enables to apply these amorphous pyrophosphates not only to cosmetics and paints, but also plastics and films.WU Wenwei FAN Yanjin WU Xuehang LIAO Sen HUANG Xiufu LI Xuanhai 2009Rare Metals2009,28,1:6

20CD40-activated B cells are more potent than immature dendritic cells to induce and expand CD41 regulatory T cells显示文摘CD4^(+)regulatory T cells(Tregs)play an important role in maintaining immune tolerance by suppressing pathologic immune responses.,The generation of large numbers of antigen-specific Tregs ex vivo is critical for the development of clinical immunotherapy based on the adoptive transfer of Tregs.Both CD40-activated B cells(CD40-B)and immature dendritic cells(imDCs)have been used as professional antigen-presenting cells(APCs)to generate antigen-specific Tregs.However,the efficiencies of CD40-B and imDCs to generate CD4^(+)Tregs have not been compared directly and the mechanism driving the generation of these Tregs remains largely unknown.In this study,we found that CD40-B exhibited mature phenotypes and were more able to induce and expand CD4^(high)'CD25^(+)Tregs than imDCs.Moreover,Tregs induced by CD40-B had greater suppressive capacity than those induced by imDCs.The generation of CD4^(high)CD25^(+)Tregs by CD40-B and imDCs is cell-cell contact dependent and partially relies on the expression of human leukocyte antigen(HLA)-DR and CD80/86.Differences in CD4^(high)CD25^(+)Treg generation efficiency were largely explained by the production of endogenous IL-2 by CD40-B.Our results suggest that CD40-B is better able to generate large numbers of antigen-specific Tregs than imDCs.Additionally,using CD40-B to generate Tregs may accelerate the clinical use of Treg-based immunotherapy in the treatment of allograft rejection,graft versus host disease(GVHD)and autoimmune diseases.Jian Zheng Yinping Liu Yu-Lung Lau Wenwei Tu 2010Cellular & Molecular Immunology2010,7,1:5
