| 1 | 8-bromo-7-methoxychrysin-induced apoptosis of hepatocellular carcinoma cells involves ROS and JNK显示文摘AIM:To investigate whether the apoptotic activities of 8-bromo-7-methoxychrysin(BrMC) involve reactive oxygen species(ROS) generation and c-Jun N-terminal kinase(JNK) activation in human hepatocellular carcinoma cells(HCC).METHODS:HepG2,Bel-7402 and L-02 cell lines were cultured in vitro and the apoptotic effects of BrMC were evaluated by flow cytometry(FCM) after propidium iodide(PI) staining,caspase-3 activity using enzymelinked immunosorbent assay(ELISA),and DNA agarose gel electrophoresis.ROS production was evaluated by FCM after dichlorodihydrofluorescein diacetate(DCHFDA) probe labeling.The phosphorylation level of JNK and c-Jun protein was analyzed by Western blotting.RESULTS:FCM after PI staining showed a dose-dependent increase in the percentage of the sub-G1 cell pop-ulation(P < 0.05),reaching 39.0% ± 2.8% of HepG2 cells after 48 h of treatment with BrMC at 10 μmol/L.The potency of BrMC to HepG2 and Bel-7402(32.1% ± 2.6%) cells was found to be more effective than the lead compound,chrysin(16.2% ± 1.6% for HepG2 cells and 11.0% ± 1.3% for Bel-7402 cell) at 40 μmol/L and similar to 5-flurouracil(33.0% ± 2.1% for HepG2 cells and 29.3% ± 2.3% for Bel-7402 cells) at 10 μmol/L.BrMC had little effect on human embryo liver L-02 cells,with the percentage of sub-G1 cell population 5.4% ± 1.8%.Treatment of HepG2 cells with BrMC for 48 h also increased the levels of active caspase-3,in a concentration-dependent manner.z-DEVD-fmk,a caspase-3specific inhibitor,prevented the activation of caspase-3.Treatment with BrMC at 10 μmol/L for 48 h resulted in the formation of a DNA ladder.Treatment of cells with BrMC(10 μmol/L) increased mean fluorescence intensity of DCHF-DA in HepG2 cells from 7.2 ± 1.12 at 0 h to 79.8 ± 3.9 at 3 h and 89.7 ± 4.7 at 6 h.BrMC did not affect ROS generation in L-02 cells.BrMC treatment failed to induce cell death and caspase-3 activation in HepG2 cells pretreated with N-acetylcysteine(10 mmol/L).In addition,in HepG2 cells treated with BrMC(2.5,5.0,10.0 μmol/L) for 12 h,JNK activation was observed.Peak JNK activation occurred at 12 h post-treatment and this activation persisted for up to 24 h.The expression of phosphorylated JNK and c-Jun protein after 12 h with BrMC-treated cells was inhibited by N-acetylcysteine and SP600125 pre-treatment,but GW9662 had no effect.SP600125 substantially reduced BrMC-induced cell death and caspase-3 activation of HepG2 cells.N-acetylcysteine and GW9662 also attenuated induction of cell death and caspase-3 activation in HepG2 cells treated with BrMC.CONCLUSION:BrMC induces apoptosis of HCC cells by ROS generation and sustained JNK activation. | Xiao-Hong Yang Jian-Guo Cao Hong-Lin Xiang Fei Liu Yuan Lv Hunan Province China Xing Zheng | 2010 | World Journal of Gastroenterology2010，16，27： | 38 |

| 3 | Age-related rhesus macaque models of COVID-19显示文摘Background:Since December 2019,an outbreak of the Corona Virus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus(SARS-CoV-2)in Wuhan,China,has become a public health emergency of international concern.The high fatality of aged cases caused by SARS-CoV-2 was a need to explore the possible age-related phenomena with non-human primate models.Methods:Three 3-5 years old and two 15 years old rhesus macaques were intratracheally infected with SARS-CoV-2,and then analyzed by clinical signs,viral replication,chest X-ray,histopathological changes and immune response.Results:Viral replication of nasopharyngeal swabs,anal swabs and lung in old monkeys was more active than that in young monkeys for 14 days after SARS-CoV-2 challenge.Monkeys developed typical interstitial pneumonia characterized by thickened alveolar septum accompanied with inflammation and edema,notably,old monkeys exhibited diffuse severe interstitial pneumonia.Viral antigens were detected mainly in alveolar epithelial cells and macrophages.Conclusion:SARS-CoV-2 caused more severe interstitial pneumonia in old monkeys than that in young monkeys.Rhesus macaque models infected with SARS-CoV-2 provided insight into the pathogenic mechanism and facilitated the development of vaccines and therapeutics against SARS-CoV-2 infection. | Pin Yu Feifei Qi Yanfeng Xu Fengdi Li Peipei Liu Jiayi Liu Linlin Bao Wei Deng Hong Gao Zhiguang Xiang Chong Xiao Qi Lv Shuran Gong Jiangning Liu Zhiqi Song Yajin Qu Jing Xue Qiang Wei Mingya Liu Guanpeng Wang Shunyi Wang Haisheng Yu Xing Liu Baoying Huang Wenling Wang Li Zhao Huijuan Wang Fei Ye Weimin Zhou Wei Zhen Jun Han Guizhen Wu Qi Jin Jianwei Wang Wenjie Tan Chuan Qin | 2020 | Animal Models and Experimental Medicine2020，3，1： | 22 |
| 4 | Brain structural changes and their correlation with vascular disease in type 2 diabetes mellitus patients: a voxel-based morphometric study显示文摘Voxel-based morphometry has been used in the study of alterations in brain structure in type 1 diabetes mellitus patients. These changes are associated with clinical indices. The age at onset, pathogenesis, and treatment of type 1 diabetes mellitus are different from those for type 2 diabetes mellitus. Thus, type 1 and type 2 diabetes mellitus may have different impacts on brain structure. Only a few studies of the alterations in brain structure in type 2 diabetes mellitus patients using voxel-based morphometry have been conducted, with inconsistent results. We detected subtle changes in the brain structure of 23 cases of type 2 diabetes mellitus, and demonstrated that there was no significant difference between the total volume of gray and white matter of the brain of type 2 diabetes mellitus patients and that in controls. Regional atrophy of gray matter mainly occurred in the right temporal and left occipital cortex, while regional atrophy of white matter involved the right temporal lobe and the right cerebellar hemisphere. The ankle-brachial index in patients with type 2 diabetes mellitus strongly correlated with the volume of brain regions in the default mode network. The ankle-brachial index, followed by the level of glycosylated hemoglobin, most strongly correlated with the volume of gray matter in the right temporal lobe. These data suggest that voxel-based morphometry could detect small structural changes in patients with type 2 diabetes mellitus. Early macrovascular atherosclerosis may play a crucial role in subtle brain atrophy in type 2 diabetes mellitus patients, with chronic hyperglycemia playing a lesser role. | Chunxia Wang Kailiang Fu Huaijun Liu Fei Xing Songyun Zhang | 2014 | Neural Regeneration Research2014，9，16： | 15 |
| 5 | Nissen fundoplication vs proton pump inhibitors for laryngopharyngeal reflux based on p H-monitoring and symptom-scale显示文摘AIM To compare the outcomes between laparoscopic Nissen fundoplication(LNF)and proton pump inhibitors(PPIs)therapy in patients with laryngopharyngeal reflux(LPR)and typeⅠhiatal hernia diagnosed by oropharyngeal p H-monitoring and symptom-scale assessment.METHODS From February 2014 to January 2015,70 patients who were diagnosed with LPR and type I hiatal hernia and referred for symptomatic assessment,oropharyngeal p H-monitoring,manometry,and gastrointestinal endoscopy were enrolled in this study.All of the patients met the inclusion criteria.All of the patients underwent LNF or PPIs administration,and completed a2-year follow-up.Patients’baseline characteristics and primary outcome measures,including comprehensive and single symptoms of LPR,PPIs independence,and satisfaction,and postoperative complications were assessed.The outcomes of LNF and PPIs therapy were analyzed and compared. RESULTS There were 31 patients in the LNF group and 39patients in the PPI group.Fifty-three patients(25 in the LNF group and 28 in the PPI group)completed reviews and follow-up.Oropharyngeal p H-monitoring parameters were all abnormal with high acid exposure,a large amount of reflux,and a high Ryan score,associated reflux symptom index(RSI)score.There was a significant improvement in the RSI and LPR symptom scores after the 2-year follow-up in both groups(P<0.05),as well as typical symptoms of gastroesophageal reflux disease.Improvement in the RSI(P<0.005)and symptom scores of cough(P=0.032),mucus(P=0.011),and throat clearing(P=0.022)was significantly superior in the LNF group to that in the PPI group.After LNF and PPIs therapy,13 and 53 patients achieved independence from PPIs therapy(LNF:44.0%vs PPI:7.14%,P<0.001)during follow-up,respectively.Patients in the LNF group were more satisfied with their quality of life than those in the PPI group(LNF:62.49±28.68 vs PPI:44.36±32.77,P=0.004).Body mass index was significantly lower in the LNF group than in the PPI group(LNF:22.2±3.1kg/m^2 vs PPI:25.1±2.9 kg/m^2,P=0.001).CONCLUSION Diagnosis of LPR should be assessed with oropharyngeal p H-monitoring,manometry,and the symptom-scale.LNF achieves better improvement than PPIs for LPR with type I hiatal hernia. | Chao Zhang Zhi-Wei Hu Chao Yan Qiong Wu Ji-Min Wu Xing Du Dian-Gang Liu Tao Luo Fei Li Zhong-Gao Wang | 2017 | World Journal of Gastroenterology2017，23，19： | 12 |
| 6 | Performance analysis for range expansion in heterogeneous networks显示文摘In this paper,the uplink and downlink performance of a two tier heterogeneous network(HetNet)with range expansion(RE)is analyzed.Different from previous works,base stations(BSs)are modeled as a spatial Poisson point process.This model can not only capture the irregularity of the BS deployment but also lead to closed form expressions.With the analytical results,the impacts of several key parameters on the coverage and throughput performance are investigated.Our results justifies the effectiveness of RE and Pico deployment.Based on our analyses,certain attention should be made on the RE design to balance the uplink and downlink performance.Our analyses are corroborated by simulations and can thus serve as a flexible and quick guidance for system design without complicated and time consuming system level platform construction and simulation. | FEI ZeSong DING HaiChuan XING ChengWen NI JiQing KUANG JingMing | 2014 | Science China(Information Sciences)2014，57，8： | 11 |
| 7 | Artificial intelligence in drug design显示文摘Thanks to the fast improvement of the computing power and the rapid development of the computational chemistry and biology,the computer-aided drug design techniques have been successfully applied in almost every stage of the drug discovery and development pipeline to speed up the process of research and reduce the cost and risk related to preclinical and clinical trials.Owing to the development of machine learning theory and the accumulation of pharmacological data, the artificial intelligence(AI) technology, as a powerful data mining tool, has cut a figure in various fields of the drug design, such as virtual screening,activity scoring, quantitative structure-activity relationship(QSAR) analysis, de novo drug design, and in silico evaluation of absorption, distribution, metabolism, excretion and toxicity(ADME/T) properties. Although it is still challenging to provide a physical explanation of the AI-based models, it indeed has been acting as a great power to help manipulating the drug discovery through the versatile frameworks. Recently, due to the strong generalization ability and powerful feature extraction capability,deep learning methods have been employed in predicting the molecular properties as well as generating the desired molecules,which will further promote the application of AI technologies in the field of drug design. | Feisheng Zhong Jing Xing Xutong Li Xiaohong Liu Zunyun Fu Zhaoping Xiong Dong Lu Xiaolong Wu Jihui Zhao Xiaoqin Tan Fei Li Xiaomin Luo Zhaojun Li Kaixian Chen Mingyue Zheng Hualiang Jiang | 2018 | Science China(Life Sciences)2018，61，10： | 10 |
| 8 | Effects of Grazing Exclusion on Soil Carbon and Nitrogen Storage in Semi-arid Grassland in Inner Mongolia, China显示文摘The semi-arid grasslands in Inner Mongolia, China have been degraded by long-term grazing. A series of ecological restoration strategies have been implemented to improve grassland service. However, little is known about the effect of these ecological restoration practices on soil carbon and nitrogen storage. In this study, characteristics of vegetation and soil properties under continued grazing and exclusion of livestock for six years due to a nationwide conservation program—′Returning Grazing Lands to Grasslands(RGLG)′ were examined in semi-arid Hulun Buir grassland in Inner Mongolia, China. The results show that removal of grazing for six years resulted in a significant recovery in vegetation with higher above and below-ground biomass, but a lower soil bulk density and pH value. After six years of grazing exclusion, soil organic C and total N storage increased by 13.9% and 17.1%, respectively, which could be partly explained by decreased loss and increased input of C and N to soil. The effects of grazing exclusion on soil C and N concentration and storage primarily occurred in the upper soil depths. The results indicate that removal of grazing pressure within the RGLG program was an effective restoration approach to control grassland degradation in this region. However, more comprehensive studies are needed to evaluate the effectiveness of the RGLG program and to improve the management strategies for grassland restoration in this area. | WU Xing LI Zongshan FU Bojie LU Fei WANG Dongbo LIU Huifeng LIU Guohua | 2014 | Chinese Geographical Science2014，24，4： | 10 |

| 10 | Prevalence and risk factors of active pulmonary tuberculosis among elderly people in China:a population based cross-sectional study显示文摘Background:The problem of population aging is a critical public health concern in modern China,and more tuberculosis(TB)control efforts are needed to reach elderly people at high priority.In this study,we aim to determine the prevalence and identify the risk factors of TB among elderly people in China.Methods:A multistage cluster-sampled cross-sectional survey was conducted in 2013,and 27 clusters were selected from 10 counties of 10 provinces in China.All consenting participants greater than or equal to 65 years of age were screened for pulmonary TB with a chest X-ray(CXR)and a symptom questionnaire.Three sputum specimens for bacteriological examination by microscopy and culture were collected from those whose screening was positive.Prevalence was calculated,a multiple logistic regression model was performed to confirm the risk factors,and population attributable fraction(PAF)of each risk factor was calculated to indicate the public health significance.Results:Of 38888 eligible people from 27 clusters,34269 participants finished both questionnaire and physical examination.There were 193 active pulmonary TB cases,62 of which were bacteriologically confirmed.The estimated prevalence of active pulmonary TB and bacteriologically confirmed TB in those 65 years of age and older was 563.19 per 100000(95%CI:483.73-642.65)and 180.92 per 100000(95%CI:135.89-225.96),respectively.Male sex,older age,living in rural areas,underweight,diabetes,close contact of pulmonary TB(PTB)and previous TB history are all risk factors for TB.The risk of TB increased with increasing age and decreasing body mass index(BMI)after adjusting for other factors,and there is a positive dose-response relationship.Conclusions:In China,active case finding(ACF)could be implemented among elderly people aged 65 and above with underweight,diabetes,close contact history and previous TB history as a priority,which will get significant yields and be cost-effective. | Can-You Zhang Fei Zhao Yin-Yin Xia Yan-Ling Yu Xin Shen Wei Lu Xiao-Meng Wang Jin Xing Jian-Jun Ye Jian-Wei Li Fei-Ying Liu Jian-Lin Wu Lin Xu Hui Zhang Jun Cheng Li-Xia Wang | 2019 | Infectious Diseases of Poverty2019，8，1： | 9 |
| 11 | Fluorescence regional integration and differential fluorescence spectroscopy for analysis of structural characteristics and proton binding properties of fulvic acid sub-fractions显示文摘Structural characteristics and proton binding properties of sub-fractions(FA3–FA13) of fulvic acid(FA), eluted stepwise by pyrophosphate buffer were examined by use of fluorescence titration combined with fluorescence regional integration(FRI) and differential fluorescence spectroscopy(DFS). Humic-like(H-L) and fulvic-like(F-L) materials, which accounted for more than 80% of fluorescence response, were dominant in five sub-fractions of FA. Based on FRI analysis, except the response of F-L materials in FA9 and FA13, maximum changes in percent fluorescence response were less than 10% as pH was increased from 2.5 to 11.5.Contents of carboxylic and phenolic groups were compared for fluorescence peaks of FA sub-fractions based on pH-dependent fluorescence derived from DFS. Static quenching was the dominant mechanism for binding of protons by FA sub-fractions. Dissociation constants(p Ka) were calculated by use of results of DFS and the modified Stern-Volmer relationship. The p Kaof H-L, F-L, tryptophan-like and tyrosine-like materials of FA subfractions exhibited ranges of 3.17–4.06, 3.12–3.97, 4.14–4.45 and 4.25–4.76, respectively, for acidic pHs. At basic pHs, values of p Ka for corresponding materials were in ranges of 9.71–10.24, 9.62–10.99, 9.67–10.31 and 9.33–10.28, respectively. At acidic pH, protein-like(P-L)materials had greater affinities for protons than did either H-L or F-L materials. The dicarboxylic and phenolic groups were likely predominant sites of protonation for both H-L and F-L materials at both acidic and basic pHs. Amino acid groups were significant factors during proton binding to protein-like materials of FA sub-fractions at basic pH. | Fanhao Song Fengchang Wu Weiying Feng Zhi Tang John P.Giesy Fei Guo Di Shi Xiaofei Liu Ning Qin Baoshan Xing Yingchen Bai | 2018 | Journal of Environmental Sciences2018，30，12： | 9 |
| 12 | Injectable ECM hydrogel for delivery of BMSCs enabled full-thickness meniscus repair in an orthotopic rat model显示文摘Meniscal injuries have poor intrinsic healing capability and are associated with the development of osteoarthritis.Decellularized meniscus extracellular matrix(mECM)has been suggested to be efficacious for the repair of meniscus defect.However,main efforts to date have been focused on the concentration,crosslinking density and anatomical region dependence of the mECM hydrogels on regulation of proliferation and differentiation of adult mesenchymal stem cells(MSCs)in vitro 2D or 3D culture.A systematic investigation and understanding of the effect of mECM on encapsulated MSCs response and integrative meniscus repair by in vivo rat subcutaneous implantation and orthotopic meniscus injury model will be highly valuable to explore its potential for clinical translation.In this study,we investigated the in situ delivery of rat BMSCs in an injectable mECM hydrogel to a meniscal defect in a SD rat model.Decellularized mECM retained essential proteoglycans and collagens,and significantly upregulated expression of fibrochondrogenic markers by BMSCs versus collagen hydrogel alone in vitro 3D cell culture.When applied to an orthotopic model of meniscal injury in SD rat,mECM is superior than collagen I scaffold in reduction of osteophyte formation and prevention of joint space narrowing and osteoarthritis development as evidenced by histology and micro-CT analysis.Taken together,these results indicate mECM hydrogel is a highly promising carrier to deliver MSCs for long-term repair of meniscus tissue,while preventing the development of osteoarthritis. | Gang Zhong Jun Yao Xing Huang Yixuan Luo Meng Wang Jinyu Han Fei Chen Yin Yu | 2020 | Bioactive Materials2020，5，4： | 9 |
| 13 | Liraglutide alleviates cardiac fibrosis through inhibiting P4hα-1 expression in STZ-induced diabetic cardiomyopathy显示文摘Diabetic cardiomyopathy is an important contributor to morbidity and mortality of diabetic patients by causing heart failure.Interstitial and perivascular fibrosis plays a crucial role in diabetic cardiomyopathy.However,there is a lack of effective specific treatments available for diabetic cardiomyopathy.In the present study,we aim to explore the effects of Liraglutide,a GLP-1 analogue,on diabetic cardiomyopathy in STZ-induced diabetic rats fed with high-fat diet.A total of 60 male Wistar rats were randomly assigned to three groups,i.e.normal group,model group,and Liraglutide group,with 20 rats in each group.Serum levels of TC,TG,LDL-C,NEFA,and hydroxyproline were measured using commercial kits.Cardiac function was evaluated by QRS waves,LVEDd,LVESd,and LVEF.Myocardial fibrosis was measured by immunohistochemistry.Our results demonstrated that chronic administration of Liraglutide decreased the level of blood glucose and significantly alleviated lipid metabolic disturbance compared with the model group.Furthermore,Liraglutide was found to improve the damaged cardiac function.In line with this,we also found that the alleviation of cardiac dysfunction was associated with the decreased fibrosis in diabetic myocardial tissues,which was reflected by the decreased expressions of P4hα-1,COL-1,COL-3,MMP-1,and MMP-9.Our results thus suggest that Liraglutide might have a myocardial protective effect by inhibiting P4hα-1-mediated myocardial fibrosis. | Tong Zhao Huiqiang Chen Fei Xu Juan Wang Yusheng Liu Xiaowei Xing Linlin Guo Mingxiang Zhang Qinghua Lu | 2019 | Acta Biochimica et Biophysica Sinica2019，51，3： | 9 |
| 14 | An engraved artifact from Shuidonggou,an Early Late Paleolithic Site in Northwest China显示文摘Cognition and symbolic thinking are viewed as important features of modern human behavior.Engraved objects are seen as a hallmark of cognition and symbolism,and even as evidence for language.Accumulated evidences including engraved bones,ochre,ostrich eggshells and stone artifacts were unearthed from Africa,Europe,Levant even Siberia Paleolithic sites.But the archaeological evidence for this,including beads,ornaments,burials,performed objects and engraved objects,is rarely discovered in the Pleistocene of East Asia.The present paper reports an engraved stone object unearthed in the Early Late Paleolithic levels about 30 ka BP at the Shuidonggou site(SDG) in northwestern China.It was unearthed in the 1980's excavation from Lower culture unit of SDG1 but was identified in 2011 when the first author of this article observed the collection from the 1980's excavations stored in the Institute of Archaeology of Ningxia Hui Autonomous Region for further detailed lithic analysis.This lithic artifact is the first engraved non-organic object of the Paleolithic period found in China.In order to clarify the details of the incisions and to document the human intentional modifications,we used a KEYENCE VHX-600 Digital Microscope to measure and observe all the incisions in 3-dimensional perspective.Comparing the natural cracks and analyzing many details of the incisions,we argue that incisions on this stone artifact are the result of intentional behaviors by ancient humans.Also,we exclude the possible other causes including animal-induced damages,post-depositional phenomenon and unintentional by-products.Combining all these features,we suggest that the incisions were made by an intentional behavior and were probably of a non-utilitarian character.Because the nature of most other engraved objects in China is debate,we cannot get a clear scenario of the emergence and progress of modern human behavior in North China.But we infer the possible existence of a counting or recording system,or other symbolic behaviors,which reflect considerably evolved cognitive capacities or modern human behavior in the Early Late Paleolithic of East Asia. | PENG Fei GAO Xing WANG HuiMin CHEN FuYou LIU DeCheng PEI ShuWen | 2012 | Chinese Science Bulletin2012，57，35： | 8 |

| 17 | Ergodic secrecy rate of two-user MISO interference channels with statistical CSI显示文摘This paper considers a two-user multiple-input single-output(MISO) interference channel with confidential messages(IFC-CM), where the beamforming vectors at the two transmitters are jointly optimized using the closed-form Pareto-optimal parameterization. We prove that artificial noise cannot improve the secrecy rate performance, and coordinated beamforming is secrecy-rate optimal which is achieved by agreeing on the parameters between the two transmitters. We analyze the feasible set of the beamforming parameters that guarantees positiveness of the secrecy rates when the transmitters know only statistical CSI, and then analysis in the ergodic secrecy rate region is discussed. More importantly, we derive the closed form of the ergodic secrecy rates and illustrate the Pareto-optimal structure of the beamforming vectors. | FEI ZeSong NI JiQing ZHAO Di XING ChengWen WANG NiWei KUANG JingMing | 2014 | Science China(Information Sciences)2014，57，10： | 7 |
| 18 | Application of Avaatech X-ray fluorescence core-scanning in Sr/Ca analysis of speleothems显示文摘Application of X-ray fluorescence core-scanning(XRF-CS) on both marine and lake sediments has achieved remarkable results. However, its application has not been widely extended to the research on speleothems. In this study, we measure the Sr abundance and the Sr/Ca ratios of three stalagmites(two aragonite stalagmites, one calcite stalagmite) using the state-of-the-art fourth-generation Avaatech high-resolution XRF core scanner. Through comparisons among different scan paths and among different scan resolutions, as well as comparisons with inductively coupled plasma optical emission spectrometer(ICP-OES), Itrax XRF, and Artax XRF results, we confirm that the Avaatech XRF core scanner could precisely, quickly, and nondestructively analyze the high-resolution Sr abundance of speleothems. Furthermore, we combine the stalagmite δ^(18)O records to explore the paleoclimatic significance of the measured stalagmite Sr/Ca. | Dong LI Liangcheng TAN Fei GUO Yanjun CAI Youbin SUN Gang XUE Xing CHENG Hong YAN Hai CHENG R.Lawrence EDWARDS Yongli GAO Jessica KELLEY | 2019 | Science China Earth Sciences2019，62，6： | 7 |

| 20 | SPOP negatively regulates Toll-like receptor-induced inflammation by disrupting MyD88 self-association显示文摘Toll-like receptor(TLR)signaling pathways need to be tightly controlled to avoid excessive inflammation and unwanted damage to the host.Myeloid differentiation primary response gene 88(MyD88)is a critical adaptor of TLR signaling.Here,we identified the speckle-type POZ protein(SPOP)as a MyD88-associated protein.SPOP was recruited to MyD88 following TLR4 activation.TLR4 activation also caused the translocation of SPOP from the nucleus to the cytoplasm.SPOP depletion promoted the aggregation of MyD88 and recruitment of the downstream signaling kinases IRAK4,IRAK1 and IRAK2.Consistently,overexpression of SPOP inhibited the TLR4-mediated activation of NF-κB and production of inflammatory cytokines,whereas SPOP depletion had the opposite effects.Furthermore,knockdown of SPOP increased MyD88 aggregation and inflammatory cytokine production upon TLR2,TLR7 and TLR9 activation.Our findings reveal a mechanism by which MyD88 is regulated and highlight a role for SPOP in limiting inflammatory responses. | Yun-Hong Hu Yang Wang Fei Wang Yan-Ming Dong Wan-Ling Jiang Ya-Ping Wang Xing Zhong Li-Xin | 2021 | Cellular & Molecular Immunology2021，18，7： | 7 |
