4A phosphatidic acid-binding lncRNA SNHG9 facilitates LATS1 liquid–liquid phase separation to promote oncogenic YAP signaling显示文摘Long noncoding RNAs(lncRNAs)are emerging as a new class of important regulators of signal transduction in tissue homeostasis and cancer development.Liquid–liquid phase separation(LLPS)occurs in a wide range of biological processes,while its role in signal transduction remains largely undeciphered.In this study,we uncovered a lipid-associated lncRNA,small nucleolar RNA host gene 9(SNHG9)as a tumor-promoting lncRNA driving liquid droplet formation of Large Tumor Suppressor Kinase 1(LATS1)and inhibiting the Hippo pathway.Mechanistically,SNHG9 and its associated phosphatidic acids(PA)interact with the C-terminal domain of LATS1,promoting LATS1 phase separation and inhibiting LATS1-mediated YAP phosphorylation.Loss of SNHG9 suppresses xenograft breast tumor growth.Clinically,expression of SNHG9 positively correlates with YAP activity and breast cancer progression.Taken together,our results uncover a novel regulatory role of a tumor-promoting lncRNA(i.e.,SNHG9)in signal transduction and cancer development by facilitating the LLPS of a signaling kinase(i.e.,LATS1).Rui-Hua Li Tian Tian Qi-Wei Ge Xin-Yu He Cheng-Yu Shi Jun-Hong Li Zhen Zhang Fang-Zhou Liu Ling-Jie Sang Zuo-Zhen Yang Ya-Zhuo Liu Yan Xiong Qingfeng Yan Xu Li Huai-Qiang Ju Jian Liu Liang-Jing Wang Jian-Zhong Shao Wenqi Wang Tianhua Zhou Aifu Lin 2021Cell Research2021,31,10:6
5Metal-organic frameworks for electrochemical reduction of carbon dioxide: The role of metal centers显示文摘Direct electrochemical reduction of CO2 into valuable chemicals and fuel is one of the most promising approaches to address the current energy crisis and lower CO2 emission.Recently,numerous metal-organic framework(MOF)and their derived materials have extensively been developed as electrocatalysts for CO2 reduction owing to their unique structure including porosity,large specific surface area,and tunable chemical structures.In this review,the recent progress of MOF-based electrocatalysts for CO2 reduction was summarized and discussed.Detailed discussions mainly focus on the synthesis and mechanism of pristine MOFs and MOF-derived materials for electrocatalytic CO2 reduction.These examples are expected to provide clues to rational design and synthesis of stable and high-performance MOFs-based electrocatalysts for CO2 reduction.Ping Shao Luocai Yi Shumei Chen Tianhua Zhou Jian Zhang 2020Journal of Energy Chemistry2020,29,1:6

7Emerging roles of NudC family: from molecular regulation to clinical implications显示文摘Nuclear distribution gene C(Nud C) was first found in Aspergillus nidulans as an upstream regulator of Nud F, whose mammalian homolog is Lissencephaly 1(Lis1). Nud C is conserved from fungi to mammals. Vertebrate Nud C has three homologs: Nud C, Nud C-like protein(Nud CL), and Nud C-like protein 2(Nud CL2). All members of the Nud C family share a conserved p23 domain, which possesses chaperone activity both in conjunction with and independently of heat shock protein 90(Hsp90). Our group and the others found that Nud C homologs were involved in cell cycle regulation by stabilizing the components of the LIS1/dynein complex. Additionally, Nud C plays important roles in cell migration, ciliogenesis, thrombopoiesis, and the inflammatory response. It has been reported that Nud CL is essential for the stability of the dynein intermediate chain and ciliogenesis via its interaction with the dynein 2 complex. Our data showed that Nud CL2 regulates the LIS1/dynein pathway by stabilizing LIS1 with Hsp90 chaperone. The fourth distantly related member of the Nud C family, CML66, a tumor-associated antigen in human leukemia, contains a p23 domain and appears to promote oncogenesis by regulating the IGF-1R-MAPK signaling pathway. In this review, we summarize our current knowledge of the Nud C family and highlight its potential clinical relevance.Qiqin Fu Wei Wang Tianhua Zhou Yuehong Yang 2016Science China(Life Sciences)2016,59,5:4
8TRIM47 is a novel endothelial activation factor that aggravates lipopolysaccharide-induced acute lung injury in mice via K63-linked ubiquitination of TRAF2显示文摘Endothelial activation plays an essential role in the pathogenesis of sepsis-induced acute lung injury,however,the detailed regulatory mechanisms remain largely unknown.Here,we reported that TRIM47,an E3 ubiquitin ligase of the tripartite motifcontaining protein family,was highly expressed in vascular endothelial cells.TRIM47-deficient mice were effectively resistant to lipopolysaccharide(LPS)-induced acute lung injury and death by attenuating pulmonary inflammation.TRIM47 was upregulated during TNFα-induced endothelial activation in vitro.Knockdown of TRIM47 in endothelial cells inhibited the transcription of multiple pro-inflammatory cytokines,reduced monocyte adhesion and the expression of adhesion molecules,and suppressed the secretion of IL-1βand IL-6 in endothelial cells.By contrast,overexpression of TRIM47 promoted inflammatory response and monocyte adhesion upon TNFαstimulation.In addition,TRIM47 was able to activate the NF-κB and MAPK signaling pathways during endothelial activation.Furthermore,our experiments revealed that TRIM47 resulted in endothelial activation by promoting the K63-linked ubiquitination of TRAF2,a key component of the TNFαsignaling pathway.Taken together,our studies demonstrated that TRIM47 as a novel activator of endothelial cells,promoted LPS-induced pulmonary inflammation and acute lung injury through potentiating the K63-linked ubiquitination of TRAF2,which in turn activates NF-κB and MAPK signaling pathways to trigger an inflammatory response in endothelial cells.Yisong Qian Ziwei Wang Hongru Lin Tianhua Lei Zhou Zhou Weilu Huang Xuehan Wu Li Zuo Jie Wu Yu Liu Ling-Fang Wang Xiao-Hui Guan Ke-Yu Deng Mingui Fu Hong-Bo Xin 2022Signal Transduction and Targeted Therapy2022,7,6:2

10Low‐intensity pulsed ultrasound ameliorates angiotensin II-induced cardiac fibrosis by alleviating inflammation via a caveolin-1-dependent pathway显示文摘Objective:Cardiac hypertrophy and fibrosis are major pathological manifestations observed in left ventricular remodeling induced by angiotensin II(AngII).Low-intensity pulsed ultrasound(LIPUS)has been reported to ameliorate cardiac dysfunction and myocardial fibrosis in myocardial infarction(MI)through mechano-transduction and its downstream pathways.In this study,we aimed to investigate whether LIPUS could exert a protective effect by ameliorating AngII-induced cardiac hypertrophy and fibrosis and if so,to further elucidate the underlying molecular mechanisms.Methods:We used AngII to mimic animal and cell culture models of cardiac hypertrophy and fibrosis.LIPUS irradiation was applied in vivo for 20 min every 2 d from one week before mini-pump implantation to four weeks after mini-pump implantation,and in vitro for 20 min on each of two occasions 6 h apart.Cardiac hypertrophy and fibrosis levels were then evaluated by echocardiographic,histopathological,and molecular biological methods.Results:Our results showed that LIPUS could ameliorate left ventricular remodeling in vivo and cardiac fibrosis in vitro by reducing AngII-induced release of inflammatory cytokines,but the protective effects on cardiac hypertrophy were limited in vitro.Given that LIPUS increased the expression of caveolin-1 in response to mechanical stimulation,we inhibited caveolin-1 activity with pyrazolopyrimidine 2(pp2)in vivo and in vitro.LIPUS-induced downregulation of inflammation was reversed and the anti-fibrotic effects of LIPUS were absent.Conclusions:These results indicated that LIPUS could ameliorate AngII-induced cardiac fibrosis by alleviating inflammation via a caveolin-1-dependent pathway,providing new insights for the development of novel therapeutic apparatus in clinical practice.Kun ZHAO Jing ZHANG Tianhua XU Chuanxi YANG LiqingWENG TingtingWU XiaoguangWU Jiaming MIAO Xiasheng GUO Juan TU Dong ZHANG Bin ZHOU Wei SUN Xiangqing KONG 2021Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2021,22,10:2
11Phenylpropanoid Derivatives Are Essential Components of Sporopollenin in Vascular Plants显示文摘The outer wall of pollen and spores,namely the exine,is composed of sporopollenin,which is highly resistant to chemical reagents and enzymes.In this study,we demonstrated that phenylpropanoid pathway derivatives are essential components of sporopollenin in seed plants.Spectral analyses showed that the autofluorescence of Lilium and Arabidopsis sporopollenin is similar to that of lignin.Thioacidolysis and NMR analyses of pollen from Lilium and Cryptomeria further revealed that the sporopollenin of seed plants contains phenylpropanoid derivatives,including p-hydroxybenzoate(p-BA),p-coumarate(p-CA),ferulate(FA),and lignin guaiacyl(G)units.The phenylpropanoid pathway is expressed in the tapetum in Arabidopsis,consistent with the fact that the sporopollenin precursor originates from the tapetum.Further germination and comet assays showed that this pathway plays an important role in protection of pollen against UV radiation.In the pteridophyte plant species Ophioglossum vulgatum and Lycopodium clavata,phenylpropanoid derivatives including p-BA and p-CA were also detected,but G units were not.Taken together,our results indicate that phenylpropanoid derivatives are essential for sporopollenin synthesis in vascular plants.In addition,sporopollenin autofluorescence spectra of bryophytes,such as Physcomitrella and Haplocladium,exhibit distinct characteristics compared with those of vascular plants,indicating the diversity of sporopollenin among land plants.Jinp-Shi Xue Baocai Zhang HuaDong Zhan Yong-Lin Lv Xin-Lei Jia TianHua Wang Nai-Ying Yang Yu-Xia Lou Zai-Bao Zhang Wen-Jing Hu Jinshan Gui Jianguo Cao Ping Xu Yihua Zhou Jin-Feng Hu Laigeng Li Zhong-Nan Yang 2020Molecular Plant2020,13,11:2
12Highly efficient acousto-optic modulation using nonsuspended thin-fil1m lithium niobate-chalcogenide hybrid waveguides显示文摘A highly efficient on-chip acousto-optic modulator is as a key component and occupies an exceptional position in microwave-to-optical conversion.Homogeneous thin-film lithium niobate is preferentially employed to build the suspended configuration for the acoustic resonant cavity,with the aim of improving the modulation efficiency of the device.However,the limited cavity length and complex fabrication recipe of the suspended prototype restrain further breakthroughs in modulation efficiency and impose challenges for waveguide fabrication.In this work,based on a nonsuspended thin-film lithium niobate-chalcogenide glass hybrid Mach-Zehnder interferometer waveguide platform,we propose and demonstrate a built-in push-pull acousto-optic modulator with a half-wave-voltage-length product VnL as low as 0.03 V cm that presents a modulation efficiency comparable to that of a state-of-the-art suspended counterpart.A microwave modulation link is demonstrated using our developed built-in push-pull acousto-optic modulator,which has the advantage of low power consumption.The nontrivial acousto-optic modulation performance benefits from the superior photoelastic property of the chalcogenide membrane and the completely bidirectional participation of the antisymmetric Rayleigh surface acoustic wave mode excited by the impedance-matched interdigital transducer,overcoming the issue of low modulation efficiency induced by the incoordinate energy attenuation of acoustic waves applied to the Mach-Zehnder interferometer with two arms in traditional push-pull acousto-optic modulators.Lei Wan Zhiqiang Yang Wenfeng Zhou Meixun Wen Tianhua Feng Siqing Zeng Dong Liu Huan Li Jingshun Ppan Ning Zhu Weiping Liu Zhaohui Li 2022Light(Science & Applications)2022,11,6:2

15Engineering nanointerface of molybdenum-based heterostructures to boost the electrocatalytic hydrogen evolution reaction显示文摘Rational heterostructure-design in electrocatalysts represents a promising approach toward high performance in the electrocatalytic hydrogen evolution reaction(HER).In specific,optimizing the H adsorption behavior at the surface/interface of heterostructure is of key importance to improve the catalytic performance.Herein,we demonstrate the construction of a heterostructure from a well-defined oxygenbridged Co/Mo heterometallic zeolitic imidazolate framework(MOZ) as an efficient electrocatalyst for HER.The optimized hybrid exhibits high catalytic activity and stability in electrolytes with a wide pH range.Detailed XPS,XAS and theoretical studies reveal that the regulation of metal species can tailor the lattice of Mo_(2)C within the hybrid and induce the formation of defect sites,which could not only induce surface charge transfer between the atoms and provide an additional active site,but also affect the H adsorption behavior at the interface of a heterostructure.This work provides an effective strategy to design a heterostructure with tailored active sites for energy conversion.Tong Liu Shuqing Zhou Jing Qi Kaiwen Wang Lirong Zheng Qingming Huang Tianhua Zhou Jian Zhang 2021Journal of Energy Chemistry2021,30,7:1

17Boosting Efficient Ammonia Synthesis over Atomically Dispersed Co-Based Catalyst via the Modulation of Geometric and Electronic Structures显示文摘Ammonia(NH_(3))synthesis at mild conditions is of great significance,while the significant bottleneck of this process is the activation of N_(2) to realize the desired NH_(3) synthesis performance,which requires deep insight and rational design of active sites at the atomic level.Here,were synthesized atomically dispersed Co-based catalysts with different Co-N coordination numbers(CNs)to explore the coordination-sensitive NH_(3) synthesis reaction for the first time.Our studies showed that Co-based catalysts increased the NH_(3) synthesis rate gradually with a decrease in CN.The Co-N_(2) catalyst exhibited the highest NH_(3) synthesis rate of 85.3 mmol gCo^(−1) h^(−1) at 300℃ and 1 MPa,which outperformed most of the previously reported Co-based catalysts.Various characterizations and theoretical calculations demonstrated that atomically dispersed Co catalyst with low CN could generate more unoccupied Co 3d charges and tetrahedral cobalt(Ⅱ)sites.The unoccupied Co 3d charge,in turn,promoted the electron donation from the Co active center to the antibonding π-orbital(π*)of N_(2) and expedites N_(2) hydrogenation.Furthermore,the Co-N_(2) catalyst with more tetrahedral cobalt(II)sites could effectively facilitate the desorption of N-containing intermediate species(such as*NH_(3) and*N_(2)H_(4))to obtain a high NH_(3) synthesis rate.Yanliang Zhou Congying Wang Xuanbei Peng Tianhua Zhang Xiuyun Wang Yafei Jiang Haifeng Qi Lirong Zheng Jianxin Lin Lilong Jiang 2022CCS Chemistry2022,4,5:1
