| 2 | A Private User Data Protection Mechanism in TrustZone Architecture Based on Identity Authentication显示文摘In Trust Zone architecture, the Trusted Application(TA) in the secure world does not certify the identity of Client Applications(CA) in the normal world that request data access, which represents a user data leakage risk. This paper proposes a private user data protection mechanism in Trust Zone to avoid such risks. We add corresponding modules to both the secure world and the normal world and authenticate the identity of CA to prevent illegal access to private user data. Then we analyze the system security, and perform validity and performance tests.The results show that this method can perform effective identity recognition and control of CA to protect the security of private user data. After adding authentication modules, the data operation time of system increases by about0.16 s, an acceptable price to pay for the improved security. | Bo Zhao Yu Xiao Yuqing Huang Xiaoyu Cui | 2017 | Tsinghua Science and Technology2017,22,2: | 3 |
| 3 | Characteristics of oral methicillin-resistant Staphylococcus epidermidis isolated from dental plaque显示文摘The oral microbial community is widely regarded as a latent reservoir of antibiotic resistance genes. This study assessed the molecular epidemiology, susceptibility profile, and resistance mechanisms of 35 methicillin-resistant Staphylococcus epidermidis(MRSE) strains isolated from the dental plaque of a healthy human population. Broth microdilution minimum inhibitory concentrations(MICs) revealed that all the isolates were nonsusceptible to oxacillin and penicillin G. Most of them were also resistant to trimethoprim(65.7%) and erythromycin(54.3%). The resistance to multiple antibiotics was found to be largely due to the acquisition of plasmid-borne genes. The mec A and dfr A genes were found in all the isolates, mostly dfr G(80%), aac A-aph D(20%), aad D(28.6%), aph A3(22.9%), msr A(5.7%), and the erm C gene(14.3%). Classical mutational mechanisms found in these isolates were mainly efflux pumps such as qac A(31.4%), qac C(25.7%), tet K(17.1%), and nor A(8.6%). Multilocus sequence type analysis revealed that sequence type 59(ST59) strains comprised 71.43% of the typed isolates, and the e BURST algorithm clustered STs into the clonal complex 2-II(CC2-II). The staphyloccoccal cassette chromosome mec(SCCmec) type results showed that 25(71.43%) were assigned to type IV. Moreover, 88.66% of the isolates were found to harbor six or more biofilm-associated genes. The aap, atl E, embp, sdr F, and IS256 genes were detected in all 35 isolates. This research demonstrates that biofilm-positive multipleantibiotic-resistant ST59-SCCmec IV S. epidermidis strains exist in the dental plaque of healthy people and may be a potential risk for the transmission of antibiotic resistance. | Boyu Tang Tao Gong Yujia Cui Lingyun Wang Chao He Miao Lu Jiamin Chen Meiling Jing Anqi Zhang Yuqing Li | 2020 | International Journal of Oral Science2020,12,2: | 2 |

| 6 | EXPRESSION OF CALCITONING GENE-RELATED PEPTIDE IN VASCULAR SMOOTH MUSCLE CELLS BY RETROVIRUS-MEDIATED GENE TRANSFER显示文摘Background:The contemporary treatment of coronary athero-occlusive disease bypercutaneous transluminal coronary angioplasty is hampered by maladaptive woundhealing,resulting in significant failure rates.Morbid sequelae include smooth musclecell(SMC)hyperplesia and restenosis due to vascular neointimal formation.Calcitoningene-related peptide(CGRP)has been proposed as a potential therapeutic neuopeptide forintimal hyperplastic vascular disease.Methods and Results:In this study,we investigated CGRP gene expression in culturedrat thoracic arterial smooth muscle cells(SMCs)A replication-defective,recombinantretrovirus containing human α-CGRP cDNA(termed pRCGRP)was constructed and usedto infect SMCs in culture.Following selection with G418,cells traneduced by pRCGRPwere found to express CGRP and stable transfer of CGRP in SMCs was achieved withretroviral vector.CGRP gene expression was observed only when cultured SMCs weretransduced with vectors containing the CGRP cDNA No evidence of similar geneexpression was observed in nontranfected or empty vector transfected SMCs CGRPexpressed in the transduced SMCs was secreted into culture medium and was detected byradioimmunoassay(RIA).The highest level of CGRP gene product reached 18.2±0.6pM,whereas that of normal and control group were undectable.Conclusions:The fact that a recombinant gene can be readily inserted and efficientlyexpressed in vascular smooth muscle cells suggests that CGRP gene may be served as apromising candidate gene for gene therapy in atharosclerosis and restenosis.Retroviralmediated CGRP gene transfer may he used to treat atherosclerosis and restenosis. | Junfeng CUI Xiaofeng JIN Tong Zhang Yuqing HUO Chengbin XU people’s Hospital,Beijing Medical University,Beijing 100044,China Address for correspondence:Professor Xu Cheng-bin,Department of Cardiology,People’s Hospital,Beijing Medical Universy,Beijing 100044,Tel:68314422-5347 | 1998 | 中国介入心脏病学杂志1998,6,4: | 1 |
| 7 | The OX40-TRAF6 axis promotes CTLA-4 degradation to augment antitumor CD8^(+)T-cell immunity显示文摘Immune checkpoint blockade(ICB),including anti-cytotoxic T-lymphocyte associated protein 4(CTLA-4),benefits only a limited number of patients with cancer.Understanding the in-depth regulatory mechanism of CTLA-4 protein stability and its functional significance may help identify ICB resistance mechanisms and assist in the development of novel immunotherapeutic modalities to improve ICB efficacy.Here,we identified that TNF receptor-associated factor 6(TRAF6)mediates Lys63-linked ubiquitination and subsequent lysosomal degradation of CTLA-4.Moreover,by using TRAF6-deficient mice and retroviral overexpression experiments,we demonstrated that TRAF6 promotes CTLA-4 degradation in a T-cell-intrinsic manner,which is dependent on the RING domain of TRAF6.This intrinsic regulatory mechanism contributes to CD8+T-cell-mediated antitumor immunity in vivo.Additionally,by using an OX40 agonist,we demonstrated that the OX40-TRAF6 axis is responsible for CTLA-4 degradation,thereby controlling antitumor immunity in both tumor-bearing mice and patients with cancer.Overall,our findings demonstrate that the OX40-TRAF6 axis promotes CTLA-4 degradation and is a potential therapeutic target for the improvement of T-cell-based immunotherapies. | Jizhang Yu Jikai Cui Xi Zhang Heng Xu Zhang Chen Yuan Li Yuqing Niu Song Wang Shuan Ran Yanqiang Zou Weicong Ye Dan Zhang Cheng Zhou Jiahong Xia Jie Wu | 2023 | Cellular & Molecular Immunology2023,20,12: | 0 |
| 8 | Cytoplasmic YAP1-mediated ESCRT-III assembly promotes autophagic cell death and is ubiquitinated by NEDD4L in breast cancer显示文摘Background:Nuclear Yes1-associated transcriptional regulator(YAP1)promotes tumor progression.However,the function of cytoplasmic YAP1 in breast cancer cells and its impact on the survival of breast cancer patients remain unclear.Our research aimed to explore the biological function of cytoplasmic YAP1 in breast cancer cells and the possibility of cytoplasmic YAP1 as a predictive marker of breast cancer survival.Methods:We constructed cell mutant models,including NLS-YAP15SA(nuclear localized),YAP1S94A(incapable of binding to the TEA domain transcription factor family)and YAP1S127D(cytoplasmic localized),and used Cell Counting Kit-8(CCK-8)assays,5-ethynyl-2’-deoxyuridine(EdU)incorporation assays,and Western blotting(WB)analysis to detect cell proliferation and apoptosis.The specific mechanism of cytoplasmic YAP1-mediated endosomal sorting complexes required for transport III(ESCRT-III)assembly was studied by co-immunoprecipitation,immunofluorescence staining,and WB analysis.Epigallocatechin gallate(EGCG)was used to simulate YAP1 retention in the cytoplasm in in vitro and in vivo experiments to study the function of cytoplasmic YAP1.YAP1 binding to NEDD4-like E3 ubiquitin protein ligase(NEDD4L)was identified using mass spectrometry and was verified in vitro.Breast tissue microarrays were used to analyze the relationship between cytoplasmic YAP1 expression and the survival of breast cancer patients.Results:YAP1 was mainly expressed in the cytoplasm in breast cancer cells.Cytoplasmic YAP1 promoted autophagic death of breast cancer cells.Cytoplasmic YAP1 bound to the ESCRT-III complex subunits charged multivesicular body protein 2B(CHMP2B)and vacuolar protein sorting 4 homolog B(VPS4B),promoting assembly of CHMP2B-VPS4B and activating autophagosome formation.EGCG retained YAP1 in the cytoplasm,promoting the assembly of CHMP2B-VPS4B to promote autophagic death of breast cancer cells.YAP1 bound to NEDD4L,and NEDD4L mediated ubiquitination and degradation of YAP1.Breast tissue microarrays revealed that high levels of cytoplasmic YAP1 were beneficial to the survival of breast cancer patients.Conclusions:Cytoplasmic YAP1 mediated autophagic death of breast cancer cells by promoting assembly of the ESCRT-III complex;furthermore,we established a new breast cancer survival prediction model based on cytoplasmic YAP1 expression. | Yan Guo Yuqing Cui Yangyang Li Xiaoying Jin Dandan Wang Mengxia Lei Fengzhi Chen Yali Liu Jinwen Xu Guanyu Yao Guangchun Zeng Xuesong Chen | 2023 | Cancer Communications2023,43,5: | 0 |
| 9 | The ionome and proteome landscape of aging in laying hens and relation to egg white quality显示文摘The ionome is essential for maintaining body function and health status by participating in diverse key biological processes.Nevertheless, the distribution and utilization of ionome among different organs and how aging impacts the ionome leading to a decline in egg white quality remain unknown. Thus, we used inductively coupled plasma mass spectrometry(ICP-MS) to analyze 35 elements and their isotopic contents in eight organs of laying hens at 35, 72, and 100 weeks. Moreover, the magnum proteome, amino acids in egg white, and egg white quality were analyzed in laying hens at three different ages using 4D proteomics techniques, an amino acid analyzer, and an egg quality analyzer. Across the organs, we identified varying distribution patterns among macroelements(Mg24, Ca43/44, K39, and P31), transition metals(Zn64/66, Cu63/65, Fe56/57, and Mn55), and toxic elements(Pb208, Ba137, and Sr86). We observed an organ-specific aging pattern characterized by the accumulation of toxic elements(Pb208, Ba137, and Sr86) and calcification in the small intestine. Additionally, a decrease in the utilization of essential trace elements selenium(Se78/82) and manganese(Mn55) was noted in the oviduct. By analyzing ionome in tandem with egg quality, egg white amino acids, and proteome, we unveiled that the reduction of selenium and manganese concentrations in the magnum during the aging process affected amino acid metabolism, particularly tryptophan metabolism, thereby inhibiting the amino acid synthesis in the magnum. Furthermore, it accelerated the senescence of magnum cells through necroptosis activation, leading to a decline in the albumen secretion function of the magnum and subsequently reducing egg white quality.Overall, this study provides insights into the evolution of 35 elements and their isotopes across 8 organs of laying hens with age.It also reveals the elemental composition, interactions, and utilization patterns of these organs, as well as their correlation with egg white quality. The present study highlights the significance of ionome and offers a comprehensive perspective on the selection of ionome for regulating the aging of laying hens. | Guang Li Yuqing Feng Jian Cui Qihang Hou Tanfang Li Meiting Jia Zhengtian lv Qiuyu Jiang Ying Wang Ming Zhang Lin Wang Zengpeng Lv Junyou Li Yuming Guo Bingkun Zhang | 2023 | Science China(Life Sciences)2023,66,9: | 0 |
| 10 | Sulfation of the extracellular polysaccharide from the edible fungus Stropharia rugosoannulata with its antioxidant activity显示文摘An acidic extracellular polysaccharide(EPS)was gained from Stropharia rugosoannulata fermentation broth by the alcohol precipitate method.Sulfated derivative of EPS(S-EPS)was gained by chlorosulfonic acid-pyridine method and the conditions were as follows:pyridine as the reaction solvent,temperature 80°C,and reaction time 90 min.The chemical structure and chain conformation of EPS and S-EPS were characterized by FT-IR,NMR and size exclusion chromatography(SEC)coupled with multi-angle laser light scattering(MALLS)detection.FT-IR spectra indicated the sulfated group was linked to the polymer.The EPS mainly consists of mannose,glucose and glucuronic acid,and the glycosidic bond type is mainly(1→4)-linked and(1→6)-linked.C6 and C2 were substituted by sulfate groups.The EPS was degraded into smaller molecular weight(Mw)polysaccharides with the larger molecular size(Rg)after sulfation and S-EPS has better hydrophilicity.Moreover,the sulfated derivative S-EPS was found to have a better scavenging ability on hydroxyl radicals than EPS.It proved that the chemical modification of S.rugosoannulata polysaccharides by sulfation effectively enhanced their antioxidant activity. | Hui Hao Chun Cui Yuqing Xing Xuewei Jia Bingjie Ma Wenyi Kang Tianxiao Li Mingqi Gao Chunping Xu | 2023 | Journal of Future Foods2023,3,1: | 0 |

| 12 | Boosting wheat functional genomics via an indexed EMS mutant library of KN9204显示文摘A better understanding of wheat functional genomics can improve targeted breeding for better agronomic traits and environmental adaptation.However,the lack of gene-indexed mutants and the low transformation efficiency of wheat limit in-depth gene functional studies and genetic manipulation for breeding.In this study,we created a library for KN9204,a popular wheat variety in northern China,with a reference genome,transcriptome,and epigenome of different tissues,using ethyl methyl sulfonate(EMS)mutagenesis.This library contains a vast developmental diversity of critical tissues and transition stages.Exome capture sequencing of 2090 mutant lines using KN9204 genome-designed probes revealed that 98.79%of coding genes had mutations,and each line had an average of 1383 EMS-type SNPs.We identified new allelic variations for crucial agronomic trait-related genes such as Rht-D1,Q,TaTB1,and WFZP.We tested 100 lines with severemutations in 80 NAC transcription factors(TFs)under drought and salinity stress and identified 13 lines with altered sensitivity.Further analysis of three lines using transcriptome and chromatin accessibility data revealed hundreds of direct NAC targets with altered transcription patterns under salt or drought stress,including SNAC1,DREB2B,CML16,and ZFP182,factors known to respond to abiotic stress.Thus,we have generated and indexed a KN9204 EMS mutant library that can facilitate functional genomics research and offer resources for genetic manipulation of wheat. | Dongzhi Wang Yongpeng Li Haojie Wang Yongxin Xu Yiman Yang Yuxin Zhou Zhongxu Chen Yuqing Zhou Lixuan Gui Yi Guo Chunjiang Zhou Wenqiang Tang Shuzhi Zheng Lei Wang Xiulin Guo Yingjun Zhang Fa Cui Xuelei Lin Yuling Jiao Yuehui He Junming Li Fei He Xigang Liu Jun Xiao | 2023 | Plant Communications2023,4,4: | 0 |
