| 1 | Alterations of DNA damage response pathway:Biomarker and therapeutic strategy for cancer immunotherapy显示文摘Genomic instability remains an enabling feature of cancer and promotes malignant transformation.Alterations of DNA damage response(DDR)pathways allow genomic instability,generate neoantigens,upregulate the expression of programmed death ligand 1(PD-L1)and interact with signaling such as cyclic GMPe AMP synthase-stimulator of interferon genes(cGASe STING)signaling.Here,we review the basic knowledge of DDR pathways,mechanisms of genomic instability induced by DDR alterations,impacts of DDR alterations on immune system,and the potential applications of DDR alterations as biomarkers and therapeutic targets in cancer immunotherapy. | Minlin Jiang Keyi Jia Lei Wang Wei Li Bin Chen Yu Liu Hao Wang Sha Zhao Yayi He Caicun Zhou | 2021 | Acta Pharmaceutica Sinica B2021，11，10： | 12 |
| 2 | Robust Deadlock Avoidance Policy for Automated Manufacturing System With Multiple Unreliable Resources显示文摘This work studies the robust deadlock control of automated manufacturing systems with multiple unreliable resources. Our goal is to ensure the continuous production of the jobs that only require reliable resources. To reach this goal, we propose a new modified Banker's algorithm(MBA) to ensure that all resources required by these jobs can be freed. Moreover,a Petri net based deadlock avoidance policy(DAP) is introduced to ensure that all jobs remaining in the system after executing the new MBA can complete their processing smoothly when their required unreliable resources are operational. The new MBA together with the DAP forms a new DAP that is robust to the failures of unreliable resources. Owing to the high permissiveness of the new MBA and the optimality of the DAP, it is tested to be more permissive than state-of-the-art control policies. | Jianchao Luo Zhiqiang Liu Shuogang Wang Keyi Xing | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，3： | 4 |
| 3 | Global perspectives and future research directions for the phytoremediation of heavy metal-contaminated soil:A knowledge mapping analysis from 2001 to 2020显示文摘In total,9,552 documents were extracted from the Web of Science Core Collection and subjected to knowledge mapping and visualization analysis for the field of phytoremediation of HM-contaminated soil(PHMCS)with CiteSpace 5.7 R3 software.The results showed that(1)the number of publications increased linearly over the studied period.The top 10 countries/regions,institutions and authors contributing to this field were exhibited.(2)Keyword co-occurrence cluster analysis revealed a total of 8 clusters,including“Bioremediation,”“Arsenic,”“Biochar,”“Oxidative stress,”“Hyperaccumulation,”“EDTA,”“Arbuscular mycorrhizal fungi,”and“Environmental pollution”clusters(3)In total,334 keyword bursts were obtained,and the 25 strongest,longest duration,and newest keyboard bursts were analyzed in depth.The strongest keyword burst test showed that the hottest keywords could be divided into 7 groups,i.e.,“Plant bioremediation materials,”“HM types,”“Chelating amendments,”“Other improved strategies,”“Bioremediation characteristics,”“Risk assessment,”and“Other.”Almost half of the newest topics had emerged in the past 3 years,including“biochar,”“drought,”“health risk assessment,”“electrokinetic remediation,”“nanoparticle,”and“intercropping.”(4)In total,9 knowledge base clusters were obtained in this study.The studies of Ali et al.(2013),Blaylock et al.(1997),Huang et al.(1997),van der Ent et al.(2013),Salt et al.(1995),and Salt(1998),which had both high frequencies and the strongest burst scores,have had the most profound effects on PHMCS research.Finally,future research directions were proposed. | Kehui Liu Xiaojin Guan Chunming Li Keyi Zhao Xiaohua Yang Rongxin Fu Yi Li Fangming Yu | 2022 | Frontiers of Environmental Science & Engineering2022，16，6： | 4 |
| 4 | Determining the critical size of a rabbit rib segmental bone defect model显示文摘In order to establish and standardize the rabbit rib segmental bone defect model,it is of vital importance to determine rabbit rib critical size defect(CSD).According to the general time needed for spontaneous long-bone regeneration,three-month observation period was set to determine the CSD.The rabbit rib segmental bone defects with different sizes from 1 to 5cm with or without periosteum were performed in the eighth rib of 4-month-old male New Zealand rabbits and underwent Xray examinations at the 4th,8th and 12th weeks postoperatively.The gross and histological examinations at postoperative week 12 were evaluated,which showed that the critical sizes in the rabbit rib models with and without periosteum were 5 and 2 cm,respectively.This study provides prerequisite data for establishing rabbit rib CSD model and evaluating bonematerials using this model. | Fengzhen Liu Kun Chen Lei Hou Keyi Li Dawei Wang Bin Zhang Xiumei Wang | 2016 | Regenerative Biomaterials2016，3，5： | 2 |
| 5 | Suppression of ETI by PTI priming to balance plant growth and defense through an MPK3/MPK6-WRKYs-PP2Cs module显示文摘Pattern-triggered immunity(PTI)and effector-triggered immunity(ETI)are required for host defense against pathogens.Although PTI and ETI are intimately connected,the underlying molecular mechanisms remain elusive.In this study,we demonstrate that flg22 priming attenuates Pseudomonas syringae pv.tomato DC3000(Pst)AvrRpt2-induced hypersensitive cell death,resistance,and biomass reduction in Arabidopsis.Mitogen-activated protein kinases(MAPKs)are key signaling regulators of PTI and ETI.The absence of MPK3 and MPK6 significantly reduces pre-PTI-mediated ETI suppression(PES).We found that MPK3/MPK6 interact with and phosphorylate the downstream transcription factor WRKY18,which regulates the expression of AP2C1 and PP2C5,two genes encoding protein phosphatases.Furthermore,we observed that the PTI-suppressed ETI-triggered cell death,MAPK activation,and growth retardation are significantly attenuated in wrky18/40/60 and ap2c1 pp2c5 mutants.Taken together,our results suggest that the MPK3/MPK6-WRKYs-PP2Cs module underlies PES and is essential for the maintenance of plant fitness during ETI. | Dacheng Wang Lirong Wei Ting Liu Jinbiao Ma Keyi Huang Huimin Guo Yufen Huang Lei Zhang Jing Zhao Kenichi Tsuda Yiming Wang | 2023 | Molecular Plant2023，16，5： | 1 |
| 6 | Tree-ring δ^(15)N of Qinghai spruce in the central Qilian Mountains of China:Is pre-treatment of wood samples necessary?显示文摘A knowledge of the tree-ring stable nitrogen isotope ratio(δ^(15)N)can deepen our understanding of forest ecosystem dynamics by indicating the long-term availability,cycling and sources of nitrogen(N).However,the radial mobility of N blurs the interannual variations in the long-term N records.Previous studies of the chemical extraction of tree rings before analysis had produced inconsistent results and it is still unclear whether it is necessary to pre-treat wood samples from specific tree species to remove soluble N compounds before determining theδ^(15)N values.We compared the effects of pre-treatment with organic solvents and hot ultrapure water on the N concentration andδ^(15)N of tree rings from endemic Qinghai spruce(Picea crassifolia)growing in the interior of the central Qilian Mountains,China,during the last 60 a.We assessed the effects of different preparation protocols on the removal of the labile N compounds and investigated the need to pre-treat wood samples before determining theδ^(15)N values of tree rings.Increasing trends of the tree-ring N concentration were consistently observed in both the extracted and unextracted wood samples.The total N removed by extraction with organic solvents was about 17.60%,with a significantly higher amount in the sapwood section(P<0.01).Theδ^(15)N values of tree rings decreased consistently from 1960 to 2019 in both the extracted and unextracted wood samples.Extraction with organic solvents increased theδ^(15)N values markedly by about 5.2‰and reduced the variations in theδ^(15)N series.However,extraction with hot ultrapure water had little effect,with only a slight decrease in theδ^(15)N values of about 0.5‰.Our results showed that the radial pattern in the inter-ring movement of N in Qinghai spruce was not minimized by extraction with either organic solvents or hot ultrapure water.It is unnecessary to conduct hot ultrapure water extraction for the wood samples from Qinghai spruce because of its negligible effect on the removal of the labile N.Theδ^(15)N variation trend of tree rings in the unextracted wood samples was not influenced by the heartwood-sapwood transition zone.We suggest that theδ^(15)N values of the unextracted wood samples of the climate-sensitive Qinghai spruce could be used to explore the ecophysiological dynamics while focusing on the long-term variations. | WANG Ziyi LIU Xiaohong WANG Keyi ZENG Xiaomin ZHANG Yu GE Wensen KANG Huhu LU Qiangqiang | 2022 | Journal of Arid Land2022，14，6： | 1 |
| 7 | Polymer electrolytes reinforced by 2D fluorinated filler for all-solidstate Li-Fe-F conversion-type lithium metal batteries显示文摘The polyethylene oxide(PEO)based solid-state batteries are considered as promising candidates for the next-generation Li metal batteries with high energy density and safety.However,the low Li-ion conductivity and high-voltage endurability hinder the further applications of PEO-based electrolytes.To overcome these issues,herein two-dimensional(2D)CeF_(3)nanoplates with maximally exposed[001]crystal faces are introduced into the PEO matrix to expand the electrochemical window and improve Liion conduction and transport.The optimized crystal shape and crystal face anisotropy of CeF_(3)nanoplate filler reduce the crystallinity of composite solid polymer electrolyte(CSPE)via its Lewis acid-base interaction with ether oxygen of PEO.The Liaffinity[100]and Li-repellent[001]crystal faces of CeF_(3)nanoplates synergistically realize the dissociation of lithium bis(trifluoromethanesulfonyl)imide(LiTFSI),fast Li-adsorption/desorption,and Li+migration.The optimized CSPE-0.1CeF_(3)membrane enables the achievement of Li metal batteries with high endurability and stability,from the kinetically favorable Li/Li symmetric cells with long-term cycling over 8000 h.The highly reversible Li/LiFePO_(4) cells exhibit a capacity retention of 109.2 mAh·g^(−1)after 1000 cycles at 1 C,corresponding to a low capacity fading rate of 0.026%per cycle.The conversion-type allsolid-state Li/CSPE-0.1CeF_(3)/FeF_(3)cells show a high reversible capacity of 201.9 mAh·g^(−1)after long-term 600 cycles and of 231.1 mAh·g^(−1)at an ultra-high rate of 5 C. | Meng Lei Xiaoxue Wu Yangyang Liu Keyi Chen Jiulin Hu Chilin Li | 2023 | Nano Research2023，16，6： | 1 |

| 14 | Morphological characteristics of the striatal neural pathway by biotinylated dextran amine tracing in rats显示文摘Using neural pathway tracing and immunohistochemical technique, the striato-direct pathway (BDA3 kDa injected into the rat lateral globus pallidus) and striato-indirect pathway (BDA3 kDa injected into the substantia nigra pars reticulata) neurons were specifically labeled, and then subjected to double-labeled immunohistochemistry for mu-OPIOID Receptor (specifically-labeled striatal patch compartment), D1, and D2, respectively. The experimental findings showed that there are no statistically significant differences in the soma diameter and the number of primary dendrites between the striato-direct (substantia nigra pars reticularis) and indirect (globus pallidum externum) neurons labeled retrograde by BDA3 kDa. In addition, these two kinds of projection neurons revealed no obvious coexistence. This evidence indicates that as a highly sensitive neural pathway tracer, BDA could yield reliably and exquisitely detailed labeling of target neurons and synaptic structures. The variance of the morphologic structures and the localization of neurons were not statistically significant between the striato-substantia nigra pars reticularis and the globus pallidum externum projection neurons. Mesencephalic and thalamic neurons correlated with striatal neurons in morphology. Especially the latter which make typical excitatory synaptic contacts with striato-direct and -indirect neurons. Thus, this evidence suggests that thalamic neurons may extensively excite striatal neurons. | Bingbing Liu Shuhua Mu Lisi Ouyang Yaxi Zhu Keyi Li Mali Zhan Zongwei Liu Yu Jia Wanlong Lei | 2011 | Neural Regeneration Research2011，6，25： | 0 |
| 15 | Single-cell transcriptome landscape and antigen receptor dynamic during SARS-CoV-2 vaccination显示文摘Vaccination by inactivated vaccine is an effective strategy to prevent the COVID-19pandemic.However,the detailed molecular immune response at single-cell level is poorly un-derstood.In this study,we systematically delineated the landscape of the pre-and post-vaccination single-cell transcriptome,TCR(T cell antigen receptor)and BCR(B cell antigen re-ceptor)expression profile of vaccinated candidates.The bulk TCR sequencing analysis of COV-ID-19 patients was also performed.Enrichment of a clonal CD8+T cell cluster expressingspecific TCR was identified in both vaccination candidates and COVID-19 patients.These clonalCD8+T cells showed high expression of cytotoxicity,phagosome and antigen presentationrelated genes.The cellecell interaction analysis revealed that monocytes and dendritic cellscould interact with these cells and initiate phagocytosis via ICAM1-ITGAM and ITGB2 signaling.Together,our study systematically deciphered the detailed immunological response duringSARS-CoV-2 vaccination and infection.It may facilitate understanding the immune responseand the T-cell therapy against COVID-19. | Xiaojian Cao Xiaohua Chen Yaqi Zhu Xiaojuan Gou Keyi Yan Bing Yang Dong Men Lei Liu Yong-an Zhang Gang Cao | 2023 | Genes & Diseases2023，10，4： | 0 |
| 16 | Identification of novel Z/W chromosome-specific markers from the giant freshwater prawn Macrobrachium rosenbergii显示文摘The giant freshwater prawn(Macrobrachium rosenbergii)is a commercially cultured species in China.A sex chromosome-specific marker is crucial for sex identification and distinguishing sex chromosomes.Here,based on the results of reduced-representation genome sequencing and genome survey of M.rosenbergii,we identified steady sex-linked markers.Further nucleotide alignment analysis revealed 83.42%nucleotide similarity between the amplified W-and Z-chromosome fragments.qPCR confirmed that Z chromosome-specific fragments were present in males approximately twice as often compared to females.Similarly,the W chromosome-specific fragments were present in super females approximately twice as often compared to females.Our findings elucidate the ZW/ZZ sex determination type and contribute to exploring sex-related or sex-determining genes present on the sex chromosomes of M.rosenbergii. | Xue Liu Lingxia Zhou Biyun Luo Hongli Qian Baoqing Ye Keyi Ma Gaofeng Qiu | 2023 | Aquaculture and Fisheries2023，8，5： | 0 |
| 17 | CsXDH1 gene promotes caffeine catabolism induced by continuous strong light in tea plant显示文摘Tea plant(Camellia sinensis)is an important cash crop with extensive adaptability in the world.However,complex environmental factors force a large variation of tea quality-related components.Caffeine is essential for the formation of bitter and fresh flavors in tea,and is the main compound of tea that improves human alertness.Continuous strong light stimulation was observed to cause caffeine reduction in tea leaves,but the mechanism is not clear.In this study,the response of tea plant to light intensity was analysed mainly by multi-omics association,antisense oligodeoxynucleotide(asODN)silencing technique,and in vitro enzyme activity assay.The results revealed multiple strategies for light intensity adaptation in tea plant,among which the regulation of chloroplasts,photosynthesis,porphyrin metabolism,and resistance to oxidative stress were prominent.Caffeine catabolism was enhanced in continuous strong light,which may be a light-adapted strategy due to strict regulation by xanthine dehydrogenase(XDH).asODN silencing and enzymatic activity assays confirmed that CsXDH1 is a protein induced by light intensity to catalyze the substrate xanthine.CsXDH1 asODN silencing resulted in significant up-regulation of both caffeine and theobromine in in vitro enzyme activity assay,but not in vivo.CsXDH1 may act as a coordinator in light intensity adaptation,thus disrupting this balance of caffeine catabolism. | Qianhui Tang Keyi Liu Chuan Yue Liyong Luo Liang Zeng Zhijun Wu | 2023 | Horticulture Research2023，10，6： | 0 |
| 18 | A novel defined risk signature of endoplasmic reticulum stress-related genes for predicting the prognosis and immune infiltration status of ovarian cancer显示文摘Endoplasmic reticulum(ER)stress,as an emerging hallmark feature of cancer,has a considerable impact on cell proliferation,metastasis,invasion,and chemotherapy resistance.Ovarian cancer(OvCa)is one of the leading causes of cancer-related mortality across the world due to the late stage of disease at diagnosis.Studies have explored the influence of ER stress on OvCa in recent years,while the predictive role of ER stress-related genes in OvCa prognosis remains unexplored.Here,we enrolled 552 cases of ER stress-related genes involved in OvCa from The Cancer Genome Atlas(TCGA)and Gene Expression Omnibus(GEO)cohorts for the screening of prognosis-related genes.The least absolute shrinkage and selection operator(LASSO)regression was applied to establish an ER stress-related risk signature based on the TCGA cohort.A seven-gene signature revealed a favorable predictive efficacy for the TCGA,International Cancer Genome Consortium(ICGC),and another GEO cohort(P<0.001,P<0.001,and P=0.04,respectively).Moreover,functional annotation indicated that this signature was enriched in cellular response and senescence,cytokines interaction,as well as multiple immune-associated terms.The immune infiltration profiles further delineated an immunologic unresponsive status in the high-risk group.In conclusion,ER stress-related genes are vital factors predicting the prognosis of OvCa,and possess great application potential in the clinic. | Jiahang MO Shunyi RUAN Baicai YANG Yunfeng JIN Keyi LIU Xukai LUO Hua JIANG | 2023 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2023，24，1： | 0 |
| 19 | Modulation of Spike Count Correlations Between Macaque Primary Visual Cortex Neurons by Difficulty of Attentional Task显示文摘Studies have shown that spatial attention remarkably affects the trial-to-trial response variability shared between neurons.Difficulty in the attentional task adjusts how much concentration we maintain on what is currently important and what is filtered as irrelevant sensory information.However,how task difficulty mediates the interactions between neurons with separated receptive fields(RFs)that are attended to or attended away is still not clear.We examined spike count correlations between single-unit activities recorded simultaneously in the primary visual cortex(V1)while monkeys performed a spatial attention task with two levels of difficulty.Moreover,the RFs of the two neurons recorded were non-overlapping to allow us to study fluctuations in the correlated responses between competing visual inputs when the focus of attention was allocated to the RF of one neuron.While increasing difficulty in the spatial attention task,spike count correlations were either decreased to become negative between neuronal pairs,implying competition among them,with one neuron(or none)exhibiting attentional enhancement of firing rate,or increased to become positive,suggesting inter-neuronal cooperation,with one of the pair showing attentional suppression of spiking responses.Besides,the modulation of spike count correlations by task difficulty was independent of the attended locations.These findings provide evidence that task difficulty affects the functional interactions between different neuronal pools in V1 when selective attention resolves the spatial competition. | Qiyi Hu Wenjuan Hu Keyi Liu Xiangdong Bu Lisha Hu Liming Li Xinyu Chai Yao Chen | 2022 | Neuroscience Bulletin2022，38，5： | 0 |
