| 1 | Southern rice black-streaked dwarf virus:A new proposed Fijivirus species in the family Reoviridae显示文摘For the past several years, a novel dwarf disease has been observed on rice (Oryza sativa) in some regions of Guangdong Province and Hainan Province, southern China. Infected plants showed stunting, dark leaf and small enations on stem and leaf back. Typical Fijivirus viroplasma containing crystalline arrayed spherical virons approximately 70―75 nm in diameter and tubular structures were detected in ultrathin sections by an electron microscope in parenchyma phloem cells of the infected plants. The virus was transmitted to rice seedlings by white-backed planthoppers, Sogatella furcifera (Hemiptera: Delphacidae), collected in the diseased fields. Analysis of dsRNA extracts from infected plants revealed ten linear segments, which were similar to the electrophoretic profile of Rice black-streaked dwarf virus (RBSDV). RT-PCR with a single primer which matched to a linker sequence ligated to both 3′ ends of the viral genomic dsRNAs resulted in amplification of genome segments 9 (S9) and 10 (S10) cDNA products. The complete nucleotide sequences of S9 and S10 were obtained from clones of the RT-PCR amplicon exhibited characteristic properties of Fijivirus including low GC content (34.5% and 35.6%), genus conserved 5′ and 3′ termini sequences and similar genome organization. Blast searches indicated that the sequences of S9 and S10 shared 68.8%―74.9% and 67.1%―77.4% nucleotide identities with those of viruses in the Fijivirus group 2, respectively. These values were similar to those among other viruses in the Fijivirus group 2 and considerably lower than those among RBSDV isolates. Phylogenetic trees based on S9 and S10 nucleotide sequences and their putative amino acid sequences showed that this virus represented a separate branch among other Fijiviruses. The virus was also detected by a nested RT-PCR assay in corn (Zea mays), barnyard grass (Echinochloa crusgalli), Juncellus serotinus and flaccidgrass (Pennisetum flaccidum) in and/or adjacent to the infected rice fields. It is proposed that this virus be considered as a new species, Southern rice black-streaked dwarf virus, in the group 2 of the genus Fijivirus in the family Reoviridae. | ZHOU GuoHui WEN JingJung CAI DeJiang LI Peng XU DongLin ZHANG ShuGuang | 2008 | Chinese Science Bulletin2008，53，23： | 124 |
| 2 | A complete sequence and comparative analysis of a SARS-associated virus(Isolate BJ01)显示文摘The genome sequence of the Severe Acute Respiratory Syndrome (SARS)-associated virus provides essential information for the identification of pathogen(s), exploration of etiology and evolution, interpretation of transmission and pathogenesis, development of diagnostics, prevention by future vaccination, and treatment by developing new drugs. We report the complete genome sequence and comparative analysis of an isolate (BJ01) of the coronavirus that has been recognized as a pathogen for SARS. The genome is 29725 nt in size and has 11 ORFs (Open Reading Frames). It is composed of a stable region encoding an RNA-dependent RNA polymerase (composed of 2 ORFs) and a variable region representing 4 CDSs (coding sequences) for viral structural genes (the S, E, M, N proteins) and 5 PUPs (putative uncharacterized proteins). Its gene order is identical to that of other known coronaviruses. The sequence alignment with all known RNA viruses places this virus as a member in the family of Coronaviridae. Thirty putative substitutions have been identified by comparative analysis of the 5 SARS- associated virus genome sequences in GenBank. Fifteen of them lead to possible amino acid changes (non-synonymous mutations) in the proteins. Three amino acid changes, with predicted alteration of physical and chemical features, have been detected in the S protein that is postulated to beinvolved in the immunoreactions between the virus and its host. Two amino acid changes have been detected in the Mprotein, which could be related to viral envelope formation. Phylogenetic analysis suggests the possibility of non-human origin of the SARS-associated viruses but provides noevidence that they are man-made. Further efforts should focus on identifying the etiology of the SARS-associated virus and ruling out conclusively the existence of otherpossible SARS-related pathogen(s). | QIN E'de ZHU Qingyu YU Man FAN Baochang CHANG Guohui SI Bingyin YANG Bao PENG Wenming JIANG Tao LIU Bohua DENG Yongqiang LIU Hong ZHANG Yu WANG Cui LI Yuquan GAN Yonghua LI Xiaoyu L Fushuang TAN Gang CAO Wuchun, YANG Ruifu Institute of Microbiology and Epidemiology, Chinese Academy of Military Medical Sciences, Beijing 100071, China WANG Jian, LI Wei, XU Zuyuan, LI Yan, WU Qingfa, LIN Wei, CHEN Weijun, TANG Lin, DENG Yajun, HAN Yujun, LI Changfeng, LEI Meng, LI Guoqing, LI Wenjie, L Hong, SHI Jianping, TONG Zongzhong, ZHANG Feng, LI Songgang, LIU Bin, LIU Siqi, DONG Wei, WANG Jun, Gane K-S Wong, YU Jun & YANG Huanming* Beijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300 National Center for Genome Information, Beijing 101300, China | 2003 | Chinese Science Bulletin2003，48，10： | 121 |
| 3 | Prevalence and risk factors of HIV and syphilis,and knowledge and risk behaviors related to HIV/AIDS among men who have sex with men in Chongqing,China显示文摘High HIV prevalence and incidence burdens have been reported in men who have sex with men(MSM)in Chongqing,China.We aimed to estimate the prevalence of HIV and other sexually transmitted infections(STIs),to appraise the knowledge and risk behaviors related to HIV/AIDS among MSM,and to analyze the possible causes of deviation between behavior and knowledge to make better strategies.We recruited 617 MSM from February to July in 2008 by using a respondent-driven sampling(RDS) method in Chongqing,China.Through the collection of questionnaire-based data and biological testing results from all objects,we launched a crosssectional survey.STATA/SE was used for data analysis by frequency,ANOVA,rank sum test and logistic regression models.MSM with syphilis(OR=4.16,95%CI:2.35-7.33,P<0.0001) were more likely to be HIV infected.Being a company employee(OR=3.64,95%CI:1.22-10.08,P<0.0001) and having bought male for sex(OR=3.52,95%CI:1.10-11.32,P<0.034) were associated with a higher probability of syphilis.MSM with younger age,higher education and greater monthly income had a higher mean knowledge score.MSM who had HIV testing had a higher mean knowledge score than those who never had.Students,venues for finding sex partners by Internet and homosexuals in MSM had a higher mean knowledge score compared to other occupations,venues for finding sex partners and sexual orientation.There is an urgent need for delivery of barrier and biomedical interventions with coordinated behavioral and structural strategies to improve the effect of HIV interventions among MSM. | Wenzhe Ma Guohui Wu Hui Zheng Wenjuan Zhang Zhihang Peng Rongbin Yu NingWang | 2016 | The Journal of Biomedical Research2016，30，2： | 9 |
| 4 | Nucleocytoplasmic Trafficking of the Arabidopsis WD40 Repeat Protein XIW1 Regulates ABI5 Stability and Abscisic Acid Responses显示文摘WD40 repeat-containing proteins(WD40 proteins)serve as versatile scaffolds for protein-protein interac-tions,modulating a variety of cellular processes such as plant stress and hormone responses.Here we report the identification of a WD40 protein,XIW1(for XPO1-interacting WD40 protein 1),which positively regulates the abscisic acid(ABA)response in Arabidopsis.XIW1 is located in the cytoplasm and nucleus.We found that it interacts with the nuclear transport receptor XPO1 and is exported by XPO1 from the nucleus.Mutation of XIW1 reduces the induction of ABA-responsive genes and the accumulation of ABA Insensitive 5(ABI5),causing mutant plants with ABA-insensitive phenotypes during seed germination and seedling growth,and decreased drought stress resistance.ABA treatment upregulates the expression of XIW1,and both ABA and abiotic stresses promote XIW1 accumulation in the nucleus,where it interacts with ABI5.Loss of XIW1 function results in rapid proteasomal degradation of ABI5.Taken together,these findings suggest that XIW1 is a nucleocytoplasmic shuttling protein and plays a positive role in ABA responses by interacting with and maintaining the stability of ABI5 in the nucleus. | Xuezhong XU Wang Wan Guobin Jiang Yue Xi Haijian Huang Jiajia Cai Yanan Chang Cheng-Guo Duan Satendra KMangrauthia Xinxiang Peng Jian-Kang Zhu Guohui Zhu | 2019 | Molecular Plant2019，12，12： | 8 |
| 5 | Black phosphorus-based photothermal therapy with aCD47-mediated immune checkpoint blockade for enhanced cancer immunotherapy显示文摘Here,we describe a combination strategy of black phosphorus(BP)-based photothermal therapy together with anti-CD47 antibody(aCD47)-based immunotherapy to synergistically enhance cancer treatment.Tumour resistance to immune checkpoint blockades in most cancers due to immune escape from host surveillance,along with the initiation of metastasis through immunosuppressive cells in the tumour microenvironment,remains a significant challenge for cancer immunotherapy.aCD47,an agent for CD47/SIRPαaxis blockade,induces modest phagocytic activity and a low response rate for monotherapy,resulting in failures in clinical trials.We showed that BP-mediated ablation of tumours through photothermal effects could serve as an effective strategy for specific immunological stimulation,improving the inherently poor immunogenicity of tumours,which is particularly useful for enhancing cancer immunotherapy.BP in combination with aCD47 blockade activates both innate and adaptive immunities and promotes local and systemic anticancer immune responses,thus offering a synergistically enhanced effect in suppression of tumour progression and in inducing abscopal effects for inhibition of metastatic cancers.Our combination strategy provides a promising platform in which photothermal agents could help to enhance the therapeutic efficacy of immunotherapy. | Zhongjian Xie Minhua Peng Ruitao Lu Xiangying Meng Weiyuan Liang Zhongjun Li Meng Qiu Bin Zhang Guohui Nie Ni Xie Han Zhang Paras N.Prasad | 2020 | Light(Science & Applications)2020，9，1： | 3 |
| 6 | High efficiency ternary organic solar cells enabled by compatible dual-donor strategy with planar conjugated structures显示文摘Ternary organic solar cells(OSCs) have received extensive attention for improving the power conversion efficiency(PCE) of organic photovoltaics(OPVs). In this work, a novel donor material(ECTBD) consisting of benzodithiophene(BDT) central electron donor unit was developed and synthesized. The small molecular donor has the same central unit as PM6. The addition of ECTBD into PM6:Y6 system could improve the morphology of active blend layer. In addition, ECTBD showed good morphologically compatibility when blending with PM6:Y6 host, resulting in the improvement of fill factor and current density. As a result, the ternary devices based on PM6:ECTBD:Y6 ternary system achieved a highest PCE of 16.51% with fill factor of 76.24%, which was much higher than that of the binary devices(15.7%). Overall, this work provided an effective strategy to fabricate highly efficient ternary organic solar cells through design of the novel small molecular donor as the third component. | Sanhui Chen Tingting Yan Billy Fanady Wei Song Jinfeng Ge Qiang Wei Ruixiang Peng Guohui Chen Yingping Zou Ziyi Ge | 2020 | Science China Chemistry2020，63，7： | 2 |
| 7 | Light-Responsive Nanomaterials for Cancer Therapy显示文摘Due to its unique advantages,which include minimal invasiveness and relative clinical safety,photother-apy is considered to be a promising approach for cancer treatment.However,the treatment efficacy of phototherapy is often restricted by the limited depth of light penetration and the low targeting effect of phototherapeutic agents.The emergence of light-responsive nanomaterials offers a possible approach to achieve enhanced phototherapy potency.This review summarizes the progress in biomedical applica-tions of light-responsive nanomaterials for cancer therapy,which include photothermal therapy(PTT),photodynamic therapy(PDT),light-responsive molecule delivery,and light-controlled combination ther-apy.Future prospects are also discussed.This review aims to demonstrate the significance of light-responsive nanomaterials in cancer therapy and to provide strategies to expand the applications of phototherapy. | Xu Zhang Sheng Wang Guohui Cheng Peng Yu Jin Chang | 2022 | Engineering2022，8，6： | 1 |
| 8 | The C_(6)D_(6)detector system on the Back-n beam line of CSNS显示文摘Introduction The neutron capture cross sections are very important in the field of nuclear device design and basic physics research.Hydrogen-free liquid scintillator such as C_(6)D_(6)detectors are widely used in the neutron capture cross-sectional measurements for the low neutron sensitivity and fast time response.The Back-n white neutron source at China Spallation Neutron Source is the first spallation white neutron source in China,and it is suitable for neutron capture cross-sectional measurement.Materials and methods A C_(6)D_(6)detector system was built in the Back-n experimental station.The pulse height weighting technique was used to determine the system’s detection efficiency.The response to gamma rays of the C_(6)D_(6)detector was measured,and the energy resolution function was determined.Monte Carlo simulation with Geant4 code was carried out to get the weighting function of this C_(6)D_(6)detector system.Additionally,the systematic uncertainty of the weighting function was also determined.Conclusion According to the experimental and simulation results,this C_(6)D_(6)detector system can be used to measure neutron capture cross section. | Jie Ren Xichao Ruan Jie Bao Guangyuan Luan Wei Jiang Qi An Huaiyong Bai Ping Cao Qiping Chen Yonghao Chen Pinjing Cheng Zengqi Cui Ruirui Fan Changqing Feng Minhao Gu Fengqin Guo Changcai Han Zijie Han Guozhu He Yongcheng He Yuefeng He Hanxiong Huang Weiling Huang Xiru Huang Xiaolu Ji Xuyang Ji Haoyu Jiang Hantao Jing Ling Kang Mingtao Kang Bo Li Lun Li Qiang Li Xiao Li Yang Li Yang Li Rong Liu Shubin Liu Xingyan Liu Yinglin Ma Changjun Ning Binbin Qi Zhaohui Song Hong Sun Xiaoyang Sun Zhijia Sun Zhixin Tan Hongqing Tang Jingyu Tang Pengcheng Wang Qi Wang Taofeng Wang Yanfeng Wang Zhaohui Wang Zheng Wang Jie Wen Zhongwei Wen Qingbiao Wu Xiaoguang Wu Xuan Wu Likun Xie Yiwei Yang Han Yi Li Yu Tao Yu Yongji Yu Guohui Zhang Jing Zhang Linhao Zhang Liying Zhang Qingmin Zhang Qiwei Zhang Xianpeng Zhang Yuliang Zhang Zhiyong Zhang Yingtan Zhao Liang Zhou Zuying Zhou Danyang Zhu Kejun Zhu Peng Zhu | 2019 | Radiation Detection Technology and Methods2019，3，3： | 1 |
| 9 | Correlates of Sexual Lifestyles Among Older Adults Living With HIV in China: Findings From the Sexual Well-being (SWELL) Study显示文摘Sexual lifestyles are closely related to overall human health and well-being.Few studies have focused on sexual lifestyles among older adults living with HIV(OALHIV),especially in low-and middle-income countries.This study is a part of the sexual well-being among older adults in China(SWELL)study,which is a multicenter cross-sectional study focused on sexual health among older adults aged 50 years and older.Participants were 680 OALHIV(≥50 years old)from the SWELL study conducted from June 2020 to December 2022.Data were collected through one-on-one interviews.We used logistic regression to assess the correlates of sexual activity and sexual satis-faction.Among all participants,37.1%were sexually active.Being older,male,in a steady relationship and employed were associated with being sexually active.The prevalence of sexual satisfaction was 69.8%among sexually active OALHIV.Being homosexual and reporting a better general health status were associated with sexual satisfaction.The OALHIV who have depressive symptoms were less likely to report sexual satisfaction.To support holistic healthy aging among OALHIV,it is important for healthcare providers to be educated about the importance of enquiring about sexual activity,satisfaction and problems and addressing concerns while conveying sex-positive attitudes during clinical reviews,as these are still critical aspects of their health and well-being. | Bingyi Wang Xin Peng Leiwen Fu Xinyi Li Tongxin Shi Bowen Liang Tian Tian Thomas Fitzpatrick Zhen Lu Weijie Zhang JunyeBian Xin Xiao YingWang Yunlong Ao Lin Ouyang YongCai Maohe Yu Guohui Wu Linghua Li Xiaojun Meng Huachun Zou | 2023 | Infectious Microbes & Diseases2023，5，3： | 1 |

| 11 | Pharmacological inhibition of BAP1 recruits HERC2 to competitively dissociate BRCA1-BARD1, suppresses DNA repair and sensitizes CRC to radiotherapy显示文摘Radiotherapy is widely used in the management of advanced colorectal cancer(CRC).However,the clinical efficacy is limited by the safe irradiated dose.Sensitizing tumor cells to radiotherapy via interrupting DNA repair is a promising approach to conquering the limitation.The BRCA1-BARD1 complex has been demonstrated to play a critical role in homologous recombination(HR)DSB repair,and its functions may be affected by HERC2 or BAP1.Accumulated evidence illustrates that the ubiquitination-deubiquitination balance is involved in these processes;however,the precise mechanism for the cross-talk among these proteins in HR repair following radiation hasn’t been defined.Through activity-based profiling,we identified PT33 as an active entity for HR repair suppression.Subsequently,we revealed that BAP1 serves as a novel molecular target of PT33 via a CRISPR-based deubiquitinase screen.Mechanistically,pharmacological covalent inhibition of BAP1 with PT33 recruits HERC2 to compete with BARD1 for BRCA1 interaction,interrupting HR repair.Consequently,PT33 treatment can substantially enhance the sensitivity of CRC cells to radiotherapy in vitro and in vivo.Overall,these findings provide a mechanistic basis for PT33-induced HR suppression and may guide an effective strategy to improve therapeutic gain. | Xin Yue Tingyu Liu Xuecen Wang Weijian Wu Gesi Wen Yang Yi Jiaxin Wu Ziyang Wang Weixiang Zhan Ruirui Wu Yuan Meng Zhirui Cao Liyuan Le Wenyan Qiu Xiaoyue Zhang Zhenyu Li Yong Chen Guohui Wan Xianzhang Bu Zhenwei Peng Ran-yi Liu | 2023 | Acta Pharmaceutica Sinica B2023，13，8： | 1 |
| 12 | Hydrogen peroxide-generating nanomedicine for enhanced chemodynamic therapy显示文摘Chemodynamic therapy(CDT)is an emerging endogenous stimulation activated tumor treatment approach that exploiting iron-containing nanomedicine as catalyst to convert hydrogen peroxide(H_(2)O_(2))into toxic hydroxyl radical(·OH)through Fenton reaction.Due to the unique characteristics(weak acidity and the high H_(2)O_(2) level)of the tumor microenvironment,CDT has advantages of high selectivity and low side effect.However,as an important substrate of Fenton reaction,the endogenous H_(2)O_(2) in tumor is still insufficient,which may be an important factor limiting the efficacy of CDT.In order to optimize CDT,various H_(2)O_(2)-generating nanomedicines that can promote the production of H_(2)O_(2) in tumor have been designed and developed for enhanced CDT.In this review,we summarize recently developed nanomedicines based on catalytic enzymes,nanozymes,drugs,metal peroxides and bacteria.Finally,the challenges and possible development directions for further enhancing CDT are prospected. | Peng Yu Xiaodong Li Guohui Cheng Xu Zhang Dan Wu Jin Chang Sheng Wang | 2021 | Chinese Chemical Letters2021，32，7： | 1 |
| 13 | Traumatic brain injury stimulates sympathetic tone-mediated bone marrow myelopoiesis to favor fracture healing显示文摘Traumatic brain injury(TBI)accelerates fracture healing,but the underlying mechanism remains largely unknown.Accumulating evidence indicates that the central nervous system(CNS)plays a pivotal role in regulating immune system and skeletal homeostasis.However,the impact of CNS injury on hematopoiesis commitment was overlooked.Here,we found that the dramatically elevated sympathetic tone accompanied with TBI-accelerated fracture healing;chemical sympathectomy blocks TBIinduced fracture healing.TBI-induced hypersensitivity of adrenergic signaling promotes the proliferation of bone marrow hematopoietic stem cells(HSCs)and swiftly skews HSCs toward anti-inflammation myeloid cells within 14 days,which favor fracture healing.Knockout ofβ3-orβ2-adrenergic receptor(AR)eliminate TBI-mediated anti-inflammation macrophage expansion and TBIaccelerated fracture healing.RNA sequencing of bone marrow cells revealed that Adrb2 and Adrb3 maintain proliferation and commitment of immune cells.Importantly,flow cytometry confirmed that deletion ofβ2-AR inhibits M2 polarization of macrophages at 7th day and 14th day;and TBI-induced HSCs proliferation was impaired inβ3-AR knockout mice.Moreover,β3-andβ2-AR agonists synergistically promote infiltration of M2 macrophages in callus and accelerate bone healing process.Thus,we conclude that TBI accelerates bone formation during early stage of fracture healing process by shaping the anti-inflammation environment in the bone marrow.These results implicate that the adrenergic signals could serve as potential targets for fracture management. | Weijian Liu Wei Chen Mao Xie Chao Chen Zengwu Shao Yiran Zhang Haiyue Zhao Qingcheng Song Hongzhi Hu Xin Xing Xianyi Cai Xiangtian Deng Xinyan Li Peng Wang Guohui Liu Liming Xiong Xiao Lv Yingze Zhang | 2023 | Signal Transduction and Targeted Therapy2023，8，8： | 1 |
| 14 | Response of spikelet water status to high temperature and its relationship with heat tolerance in rice显示文摘In rice, high-temperature stress(HT) during flowering results in decreased grain yield via a reduction in spikelet fertility;however, the effect of plant water status on spikelet fertility under HT remains unknown. To investigate the relationship between spikelet water status and spikelet fertility under HT, two experiments were performed under temperature-controlled conditions using four genotypes with varying tolerance to HT. Rice plants were exposed to HT for seven consecutive days during the flowering stage under three soil water treatments(soil water potential 0, -20, and -40 kPa), as well as under hydroponic conditions in a separate experiment. HT significantly decreased spikelet fertility, pollen fertility, and anther dehiscence under each of the three water treatments. HT significantly increased the spikelet transpiration rate, and this change was accompanied by a significant decrease in the internal temperature of the spikelets. HT decreased pollen grain diameter in heat-sensitive genotypes. HT had varying effects on the water potential of panicles and anthers but increased anther soluble-sugar concentration. Different aquaporin genes showed different expression profiles under HT, and the expression levels of PIPs for plasma membrane intrinsic proteins and TIPs for tonoplast intrinsic proteins increased in anthers but decreased in glumes.Correlation analyses showed that anther dehiscence and pollen(spikelet) fertility were tightly associated with anther water status, and the expression levels of almost all anther aquaporin genes were significantly correlated with anther dehiscence under HT. In summary, an increased spikelet transpiration rate and decreased internal spikelet temperature were associated with alleviation of the effects of HT in rice genotypes with varying degrees of heat tolerance, and the response of spikelet water status to HT, involving increased total expression of aquaporins and soluble sugar content, thereby improved pollen fertility,anther dehiscence, and spikelet fertility, especially in heat-resistant genotypes. The heat-resistant genotypes N22 and SY63 may adopt different approaches to reduce heat damage. | Wencheng Wang Kehui Cui Qiuqian Hu Chao Wu Guohui Li Jianliang Huang Shaobing Peng | 2021 | The Crop Journal2021，9，6： | 1 |

| 16 | Identification of quantitative trait loci for growth traits in red swamp crayfish(Procambarus clarkii)显示文摘Genetic breeding is an important approach to improve the economic traits of aquaculture animals.Unfortunately,the genetic basis for important economic traits of red swamp crayfish,including growth-related traits,has not yet been reported.In the present study,two full-sib families and two natural populations were employed to identify quantitative trait loci(QTLs)for growth-related traits of red swamp crayfish.In total,28 QTLs for five growth-related traits,including body weight,body length,carapace length,carapace width,and abdomen length,were repeatedly identified in more than two families/populations,by means of association analysis;nine of these displayed a heterosis effect.The phenotypic variations of the five investigated traits explained by the 28 QTLs ranged from 4.2%to 19.0%.Eight additive and three heterosis QTLs were further successfully validated using comparative analysis of favoured alleles between the small and big size crayfish groups in the natural population.In conclusion,this study investigated the genetic basis of growth-related traits in red swamp crayfish,which is of great significance for their application in the future molecular breeding of the species. | Junxiao Sun Cuirong Luo Bo Peng Guohui Peng Yunfei Tan Xufeng Bai | 2023 | Aquaculture and Fisheries2023，8，6： | 0 |
| 17 | The nuclear export receptor OsXPO1 is required for rice development and involved in abiotic stress responses显示文摘The transport of proteins to and from the nucleus is necessary for many cellular processes and is one of the ways plants respond to developmental signals and environmental stresses.Nucleocytoplasmic trafficking of proteins is mediated by the nuclear transport receptor(NTR).Although NTR has been extensively studied in humans and Arabidopsis,it has rarely been identified and functionally characterized in rice.In this study,we identified exportin 1 in rice(OsXPO1)as a nuclear export receptor.OsXPO1shares high protein identity with its functional homologs in Arabidopsis and other organisms.OsXPO1localized to both the nucleus and the cytoplasm,directly interacted with the small GTPases OsRAN1and OsRAN2 in the nucleus,and mediated their nuclear export.Loss-of-function osxpo1 mutations were lethal at the seedling stage.Suppression of OsXPO1 expression in RNA interference lines produced multifaceted developmental defects,including arrested growth,premature senescence,abnormal inflorescence,and brown and mouth-opened spikelets.Overexpression of OsXPO1 in rice reduced plant height and seed-setting rate,but increased plant tolerance in response to PEG-mimicked drought stress and salt stress.These results indicate that OsXPO1 is a nuclear export receptor and acts in regulating plant development and abiotic stress responses. | Qiufei Peng Jieyu Qiu Xintong Li Xuezhong Xu Xinxiang Peng Guohui Zhu | 2023 | The Crop Journal2023，11，1： | 0 |
| 18 | Bone-targeting engineered small extracellular vesicles carrying anti-miR-6359-CGGGAGC prevent valproic acid-induced bone loss显示文摘The clinical role and underlying mechanisms of valproic acid(VPA)on bone homeostasis remain controversial.Herein,we confirmed that VPA treatment was associated with decreased bone mass and bone mineral density(BMD)in both patients and mice.This effect was attributed to VPA-induced elevation in osteoclast formation and activity.Through RNA-sequencing,we observed a significant rise in precursor miR-6359 expression in VPA-treated osteoclast precursors in vitro,and further,a marked upregulation of mature miR-6359(miR-6359)in vivo was demonstrated using quantitative real-time PCR(qRT-PCR)and miR-6359 fluorescent in situ hybridization(miR-6359-FISH).Specifically,the miR-6359 was predominantly increased in osteoclast precursors and macrophages but not in neutrophils,T lymphocytes,monocytes and bone marrow-derived mesenchymal stem cells(BMSCs)following VPA stimulation,which influenced osteoclast differentiation and bone-resorptive activity.Additionally,VPA-induced miR-6359 enrichment in osteoclast precursors enhanced reactive oxygen species(ROS)production by silencing the SIRT3 protein expression,followed by activation of the MAPK signaling pathway,which enhanced osteoclast formation and activity,thereby accelerating bone loss.Currently,there are no medications that can effectively treat VPA-induced bone loss.Therefore,we constructed engineered small extracellular vesicles(E-sEVs)targeting osteoclast precursors in bone and naturally carrying anti-miR-6359 by introducing of EXOmotif(CGGGAGC)in the 3’-end of the anti-miR-6359 sequence.We confirmed that the E-sEVs exhibited decent bone/osteoclast precursor targeting and exerted protective therapeutic effects on VPA-induced bone loss,but not on ovariectomy(OVX)and glucocorticoid-induced osteoporotic models,deepening our understanding of the underlying mechanism and treatment strategies for VPA-induced bone loss. | Xudong Xie Peng Cheng Liangcong Hu Wu Zhou Detai Zhang Samuel Knoedler Guodong Liu Yuan Xiong Hang Xue Yiqiang Hu Barbara Kern Doha Obed Adriana CPanayi Lang Chen Chenchen Yan Ze Lin Guandong Dai Bobin Mi Yingze Zhang Guohui Liu | 2024 | Signal Transduction and Targeted Therapy2024，9，2： | 0 |
| 19 | A New Model for Network Security Situation Assessment of the Industrial Internet显示文摘To address the problem of network security situation assessment in the Industrial Internet,this paper adopts the evidential reasoning(ER)algorithm and belief rule base(BRB)method to establish an assessment model.First,this paper analyzes the influencing factors of the Industrial Internet and selects evaluation indicators that contain not only quantitative data but also qualitative knowledge.Second,the evaluation indicators are fused with expert knowledge and the ER algorithm.According to the fusion results,a network security situation assessment model of the Industrial Internet based on the ER and BRB method is established,and the projection covariance matrix adaptive evolution strategy(P-CMA-ES)is used to optimize the model parameters.This method can not only utilize semiquantitative information effectively but also use more uncertain information and prevent the problem of combinatorial explosion.Moreover,it solves the problem of the uncertainty of expert knowledge and overcomes the problem of low modeling accuracy caused by insufficient data.Finally,a network security situation assessment case of the Industrial Internet is analyzed to verify the effectiveness and superiority of the method.The research results showthat this method has strong applicability to the network security situation assessment of complex Industrial Internet systems.It can accurately reflect the actual network security situation of Industrial Internet systems and provide safe and reliable suggestions for network administrators to take timely countermeasures,thereby improving the risk monitoring and emergency response capabilities of the Industrial Internet. | Ming Cheng Shiming Li Yuhe Wang Guohui Zhou Peng Han Yan Zhao | 2023 | Computers, Materials & Continua2023，，5： | 0 |
| 20 | Cholesterol modulating the orientation of His17 in hepatitis C virus p7 (5a) viroporin--A molecular dynamic simulation study显示文摘Protein p7 of HCV is a 63 amino acid channel forming membrane protein essential for the progression of viral infection and the sensitivity of this channel to small-molecule inhibitors renders p7 a potential target for novel therapies against HCV infection. Previous biochemical experiments suggested that the His17 of p7 is a pore-lining residue and solvated-exposed to participate in channel gating. However, a recent NMR structural identi fication of the p7 hexamer in dodecylphosphocholine(DPC) micelles indicated that the His17 is embedded into the protein matrix. In this work, we performed molecular dynamic simulations to bridge the controversial observations. Our results illustrated that by incorporating the cholesterol into DOPC membranes to mimic an actual membrane-like composition,the orientation of His17 in the hexameric bundles spontaneously access to the central pore region,indicating a versatile property of the p7 viroporin conformation that could be voluntarily in fluenced by its surrounding environments. | Yuebin Zhang Xiangda Peng Hong Ren Huiying Chu Yan Li Guohui Li | 2018 | Chinese Chemical Letters2018，29，5： | 0 |
