3Lycorine inhibits breast cancer growth and metastasis via inducing apoptosis and blocking Src/FAK-involved pathway显示文摘Breast cancer is the most commonly diagnosed cancer type worldwide among women and more than 90% of patients die from tumor metastasis. Lycorine, a natural alkaloid, has been widely reported possessing potential efficacy against cancer proliferation and metastasis. In our study, the anti-tumor potency on breast cancer was evaluated in vitro and in vivo for the first time. Our results indicated that lycorine inhibited breast cancer cells growth, migration and invasion as well as induced their apoptosis.In in vivo study, lycorine not only suppressed breast tumor growth in xenograft models and inhibited breast tumor metastasis in MDA-MB-231 tail vein model. More importantly, we found lycorine had less toxicity than first-line chemotherapy drug paclitaxel at the same effective dose in vivo. Furthermore, on mechanism, lycorine inhibited tumor cell migration and invasion via blocking the Src/FAK(focal adhesion kinase)-involved pathway. In conclusion, our study implied lycorine was a potential candidate for the treatment of breast cancer by inhibition of tumor growth and metastasis.Xuexiang Ying Anling Huang Yajing Xing Liping Lan Zhengfang Yi Pingqing He 2017Science China(Life Sciences)2017,60,4:15
4Characteristics of the microbial communities in the integrated vertical-flow constructed wetlands显示文摘Microorganisms play an important role in removing pollutants from constructed wetlands.We investigated the microbial characteristics in a novel integrated vertical-flow constructed wetland(IVCW) ,which has been in operation in Wuhan,China since 1998.We used phospholipid fatty acid(PLFA) and amoA gene to analyze the structure and diversity of the microbial community within the IVCW.PLFA results suggested that the amount of bacterial PLFA was significantly higher than that of fungal PLFA,but the total microbial biomass represented by PLFA index was low in the system.Microbial spatial distribution showed significantly higher bacterial(both G+and G-) and fungal biomass in the surface than in the subsurface layers.The ratios of monounsaturated to branched PLFA demonstrated that an anaerobic layer sandwiched by two aerobic layers existed in the IVCW,consistent with the redox potential results.Analysis of the amoA revealed the presence of Nitrosomonas-like sequences in the surface substrate of the downflow chamber and apparent diversities of ammonia-oxidizing bacteria in the system.These results suggest that microorganisms,despite their relatively low biomass,have inhabited the IVCW,and the results will offer some valuable information on microbe to system designers and managers.ZHOU Qiaohong,HE Feng,Zhang Liping,WANG Yanfen,WU Zhenbin State Key Laboratory of Freshwater Ecology and Biotechnology,Institute of Hydrobiology,Chinese Academy of Sciences,Wuhan 430072,China Department of Biology and Chemistry,City University of Hong Kong 2009Journal of Environmental Sciences2009,21,9:14
5Prostate cancer in Asia:A collaborative report显示文摘The incidence of prostate cancer(PCa)within Asian population used to be much lower than in the Western population;however,in recent years the incidence and mortality rate of PCa in some Asian countries have grown rapidly.This collaborative report summarized the latest epidemiology information,risk factors,and racial differences in PCa diagnosis,current status and new trends in surgery management and novel agents for castration-resistant prostate cancer.We believe such information would be helpful in clinical decision making for urologists and oncologists,health-care ministries and medical researchers.Rui Chen Shancheng Ren Ming Kwong Yiu Ng Chi Fai Wai Sam Cheng Lap Hong Ian Seiji Naito Tadashi Matsuda Elijah Kehinde Ali Kural Jason Yichun Chiu Rainy Umbas Qiang Wei Xiaolei Shi Liqun Zhou Jian Huang Yiran Huang Liping Xie Lulin Ma Changjun Yin Danfeng Xu Kexin Xu Zhangqun Ye Chunxiao Liu Dingwei Ye Xin Gao Qiang Fu Jianquan Hou Jianlin Yuan Dalin He Tiejun Pan Qiang Ding Fengshuo Jin Benkang Shi Gongxian Wang Xiuheng Liu Dongwen Wang Zhoujun Shen Xiangbo Kong Wanhai Xu Yaoliang Deng Haibo Xia Alexa NCohen Xu Gao Chuanliang Xu Yinghao Sun 2014Asian Journal of Urology2014,1,1:13
6Impact of impregnation pressure on desulfurization performance of Zn-based sorbents supported on semi-coke显示文摘High-pressure impregnation, a new preparation method for sorbents to remove H2S from hot coal gas, is introduced in this paper. Semi-coke (SC) and ZnO is selected as the support and active component of sorbent, respectively. The sorbent preparation process includes high-pressure impregnation, filtration, ovendry and calcination. The aim of this research is to primarily study the effects of the impregnation pressure on physical properties and desulfurization ability of the sorbent. The desulfurization experiment was carried out in a fixed-bed reactor at 500°C and a simulated coal gas used in this work was composed of CO (33 vol%), H2 (39 vol%), H2S (300 ppm in volume), and N2 (balance). Experimental results show that the pore structure of the SC support can be improved effectively and ZnO active component can be uniformly dispersed on the support, with the small particle size of 10-500 nm. Sorbents prepared using high-pressure impregnation have better desulfurization capacity and their active components have higher utilization rate. P20-ZnSC sorbent, obtained by high-pressure impregnation at 20 atm, has the best desulfurization ability with a sulfur capacity of 7.54 g S/100g sorbent and a breakthrough time of 44 h. Its desulfurization precision and efficiency of removing H2S from the middle temperature gases can reach <1 ppm and >99.7%, respectively, before sorbent breakthrough.Xianrong Zheng Weiren Bao Qingmai Jin Ruiyuan He Liping Chang Kechang Xie 2012Journal of Natural Gas Chemistry2012,21,1:10
7The distribution of the oil derived from Cambrian source rocks in Lunnan area,the Tarim Basin,China显示文摘There are great differences in biomarks between Cambrian oil and Middle-Upper Ordovician oil. In this stuty, the authors analyzed 40 oils found in Lunnan area by GC-MS and calculated the content of Cambrian oil in the 40 oils according to the steroid indexes of typical oil mixture and match experiment. The results show that it is a general phenomenon in Ordovician reservoir that the oil derived from Cambrian source rock mixed with the oil derived from Middle-Upper Ordovician source rock in Lunnan area, the mixture degree of the two oils is lower in Carboniferous reservoir than in Ordovician reservoir, and the oils kept in Triassic reservoir have single source, Middle-Upper Ordovician source rock. The mixture oils mainly composed of Cambrian oil (>50%) distributed in Sangtamu fault zone, and the oils found in Lunnan fault zone are Middle-Upper Ordovician oil. This distribution of oils in Lunnan area is owing to that Lunnan fault zone is located in anticline axis part, Lunnan fault zone underwent serious erosion, and the oils from Cambrian source rock accumulated in Lunnan fault zone were degraded completely during Caledonian-Hercynian movement. But the Cambrian oil accumulated in Sangtamu fault zone was not degraded completely and some of them were left for the location of Sangtamu fault zone is lower than Lunnan fault zone. Later, the oil derived from Middle-Upper Ordovician source rock mixed with the remained Cambrian oil, and the mixture oil formed in Sangtamu fault zone.MI JingKui ZHANG ShuiChang CHEN JianPing TANG LiPing HE ZhongHua 2007Chinese Science Bulletin2007,52,A01:10
8In-situ lunar dust deposition amount induced by lander landing in Chang’E-3 mission显示文摘China first in-situ lunar dust experiment is performed by a lunar dust detector in Chang’E-3 mission. The existed dust(less than 20 μm in diameter) properties, such as levitation, transportation and adhesion, are critical constraints for future lunar exploration program and even manned lunar exploration. Based on the problems discussed above, the in-situ lunar dust detector is originally designed to characterize dust deposition properties induced by lander landing as a function of environmental temperature, solar incident angle and orbit short circuit current on the northern Mare Imbrium, aiming to study lunar dust deposition properties induced by lander landing in depth. This paper begins with a brief of introduction of Chang’E-3 lunar dust detector design,followed by a series of experimental analysis of this instrument under different influencing factors, and concludes with lunar dust mass density deposition amount observed on the first lunar day is about 0.83 mg/cm^2, which is less than that observed in Apollo 11 mission because the landing site of Chang’E-3 has the youngest mare basalts comparing with previous Apollo and lunar landing sites. The young geologic environment is less weathered and thus it has thinner layer of lunar dust than Apollo missions’;hence, the amount of kicked-up lunar dust in Chang’E-3 mission is less than that in Apollo 11 mission.ZHANG HaiYan WANG Yi CHEN LiPing ZHANG He LI CunHui ZHUANG JianHong LI DeTian WANG YongJun YANG ShengSheng LI XiongYao WANG WeiDong 2020Science China(Technological Sciences)2020,63,3:9
9Percent free prostate-specific antigen for prostate cancer diagnosis in Chinese men with a PSA of 4.0-10.0 ng/mL:Results from the Chinese Prostate Cancer Consortium显示文摘Objective:To test the diagnostic performance of percent free prostate-specific antigen(%fPSA)in predicting any prostate cancer(PCa)and high-grade prostate cancer(HGPCa)in a retrospective multi-center biopsy cohort with a PSA level of 4.0e10.0 ng/mL in China.Methods:Consecutive patients with a PSA of 4.0-10.0 ng/mL who underwent transrectal ultrasound-guided biopsy were enrolled at 16 Chinese medical centers from January 1st,2010 to December 31st,2013.Total and free serum PSA determinations were performed using three types of electro-chemiluminescence immunoassays recalibrated to the World Health Organization(WHO)standard.The diagnostic accuracy of PSA,%fPSA,and %fPSA in combination with PSA(%fPSA t PSA)was determined using the area under the receiver operating characteristic(ROC)curve(AUC).Results:A total of 2310 consecutive men with PSA levels between 4.0 and 10.0 ng/mL were included,and the detection rate of PCa was 25.1%.The AUC of%fPSA and %fPSA t PSA in predicting any PCa was superior to PSA alone in men aged≥60 years(0.623 vs.0.534,p<0.0001)but not in men aged 40e59 years(0.517 vs.0.518,p=0.939).Similar result was yield in predicting HGPCa.Conclusion:In a clinical setting of Chinese men with 4.0e10.0 ng/mL PSA undergoing initial prostate biopsy,adding %fPSA to PSA can moderately improve the diagnostic accuracy for any PCa and HGPCa compared with PSA alone in patients≥60 but not in patients aged 40-59 years.Rui Chen Liping Xie Xiaobing Cai Yiran Huang Liqun Zhou Lulin Ma Xu Gao Chuanliang Xu Shancheng Ren Pengfei Shao Danfeng Xu Kexin Xu Zhangqun Ye Chunxiao Liu Dingwei Ye Li Lu Qiang Fu Jianquan Hou Jianlin Yuan Dalin He Tie Zhou Fubo Wang Biming He Yinghao Sun 2015Asian Journal of Urology2015,2,2:8
10Synergetic effects of aqueous extracts of Fuzi(Radix Aconiti Lateralis Preparata) and Tubeimu(Rhizoma Bolbostemmatis) on MDA-MB-231 and SKBR3 cells显示文摘OBJECTIVE: To test the synergistic effects of the aqueous extract of Tubeimu(Rhizoma Bolbostemmatis) and Fuzi(Radix Aconiti Lateralis Preparata) on MDA-MB-231 and SKBR3 breast cancer cells.METHODS: A combined index was created for the effects of Tubeimu(Rhizoma Bolbostemmatis) and Fuzi(Radix Aconiti Lateralis Preparata) extracts. Cell proliferation was performed by trypan blue exclusion and 3-(4,5-dimethylthiazol-2-yl)-5-(3- carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium(MTS) assays. Flow cytometry was used to assess cell cycle distribution and apoptosis. Cell migration was determined by wound-healing and transwell assays. Confocal microscopy was used to detect E-cadherin and actin filaments.RESULTS: The aqueous extract from Tubeimu(Rhizoma Bolbostemmatis) and Fuzi(Radix Aconiti Lateralis Preparata) exerted synergetic effects on the growth of MDA-MB-231 cells and G1 phase arrest.When exposed to extracts at concentrations of 62.5∶62.5 and 62.5∶31.3 μg/m L, the combination index was 0.83 and 0.74, respectively. Interestingly, 62.5∶31.3 μg/m L of combined drugs enhanced the inhibitory effect of Tubeimu(Rhizoma Bolbostemmatis)on the migration of SKBR3 cells and reduced the stimulative effect of Fuzi(Radix Aconiti Lateralis Preparata)(P < 0.01), in which cells showed an increased expression of E-cadherin and reorganization of actin filaments(P < 0.001). 62.5∶62.5 μg/m L extract also synergistically induced apoptosis of MDA-MB-231 cells(P < 0.05 and P < 0.001). Acting as the main active ingredients in the extract, tubeimoside I and acetylbenzoylaconine at 10∶10 μg/m L and 5∶2.5 μg/m L also produced inhibitory effects on the proliferation and migration of cells(P <0.01).CONCLUSION: Tubeimu(Rhizoma Bolbostemmatis)and Fuzi(Radix Aconiti Lateralis Preparata) extracts had synergic effects on MDA-MB-231 and SKBR3 cells.Chen Dan Cao Rui He Jinghua Guo Yuan Wang Liping Ji Wei Wu Xiongzhi 2016Journal of Traditional Chinese Medicine2016,36,1:8
11Characterization of the essential role of bone morphogenetic protein 9 (BMP9) in osteogenic differentiation of mesenchymal stem cells (MSCs) through RNA interference显示文摘Mesenchymal stem cells(MSCs)are multipotent stem cells and capable of differentiating into multiple cell types including osteoblastic,chondrogenic and adipogenic lineages.We previously identified BMP9 as one of the most potent BMPs that induce osteoblastic differentiation of MSCs although exact molecular mechanism through which BMP9 regulates osteogenic differentiation remains to be fully understood.Here,we seek to develop a recombinant adenovirus system to optimally silence mouse BMP9 and then characterize the important role of BMP9 in osteogenic differentiation of MSCs.Using two different siRNA bioinformatic prediction programs,we design five siRNAs targeting mouse BMP9(or simB9),which are expressed under the control of the converging H1 and U6 promoters in recombinant adenovirus vectors.We demonstrate that two of the five siRNAs,simB9-4 and simB9-7,exhibit the highest efficiency on silencing exogenous mouse BMP9 in MSCs.Furthermore,simB9-4 and simB9-7 act synergistically in inhibiting BMP9-induced expression of osteogenic markers,matrix mineralization and ectopic bone formation from MSCs.Thus,our findings demonstrate the important role of BMP9 in osteogenic differentiation of MSCs.The characterized simB9 siRNAs may be used as an important tool to investigate the molecular mechanism behind BMP9 osteogenic signaling.Our results also indicate that recombinant adenovirus-mediated expression of siRNAs is efficient and sustained,and thus may be used as an effective delivery vehicle of siRNA therapeutics.Shujuan Yan Ruyi Zhang Ke Wu Jing Cui Shifeng Huang Xiaojuan Ji Liping An Chengfu Yuan Cheng Gong Linghuan Zhang Wei Liu Yixiao Feng Bo Zhang Zhengyu Dai Yi Shen Xi Wang Wenping Luo Bo Liu Rex C.Haydon Michael J.Lee Russell R.Reid Jennifer Moriatis Wolf Qiong Shi Hue H.Luu Tong-Chuan He Yaguang Weng 2018Genes & Diseases2018,5,2:8
12Determination of Heterotic Groups and Heterosis Analysis of Yield Performance in indica Rice显示文摘To compare the heterosis levels among various groups of parental lines used extensively in China, identify foundational heterotic groups in parental pools and understand the relationship between genetic distance and heterosis performance, 16 parental lines with extensive genetic variation were selected from various sub-groups, and 39 hybrid combinations were generated and evaluated in Fujian and Hainan Provinces of China. The main results were as follows:(1) The 16 parental lines can be grouped into 7 sub-groups consisting of 1 maintainer sub-group and 6 restorer sub-groups;(2) Mean grain yield of the restorer lines was higher than that of the maintainer lines, and mean yield of parental lines was higher than that of the hybrid combinations;(3) The two best heterotic patterns were II-32A × G5 and II-32A × G6, moreover, the order of restorer sub-groups according to grain yield, from the highest to lowest, was G7, G6, G5, G4, G3 and G2; High specific combining ability values were observed for combinations of II-32A × G5, II-32A × G6 and Tianfeng A × G7;(4) Hybrid combinations derived from II-32A crossed with 13 restorer lines had higher yield trait values(mid-parent heterosis, better-parent heterosis, standard heterosis over check and specific combining ability) than any other combinations;(5) Genetic distance was positively correlated with panicle number, grain length and length-to-width ratio(P < 0.05) and negatively correlated with grain width, grain yield, seed-setting rate, as well as mid-parent heterosis, standard heterosis over check, and specific combining ability for grain yield(P < 0.01). These heterotic groups and patterns and their argonomic traits will provide useful information for future hybrid rice breeding programs.WANG Yingheng CAI Qiuhua XIE Hongguang WU Fangxi LIAN Ling HE Wei CHEN Liping XIE Hua'an ZHANG Jianfu 2018Rice science2018,25,5:8
13Significance of ultrasound evaluation of carotid atherosclerotic plaque for diagnosing ischemic cerebrovascular disease显示文摘BACKGROUND: Carotid artery is the main source for craniocerebral blood supply. Its intimal plaque formation and arterial stenosis degree both are the risk factors for ischemic cerebrovascular disease. Therefore, the close relationship of carotid atherosclerotic plaque and ischemic cerebrovascular disease, and ultrasound evaluation of carotid atherosclerotic plaque have become the hot spot in studying ischemic cerebrovascular disease. OBJECTIVE: This study was to detect the degree of carotid atherosclerosis of ischemic cerebrovascular disease patients by ultrasonography, and to analyze the situation of carotid atherosclerosis and its relationship with clinic. DESIGN: Clinical randomized concurrent control experiment. SETTING: Lintong Convalescent Hospital of Lanzhou Military Area Command of Chinese PLA. PARTICIPANTS: Totally 60 outpatients and inpatients with ischemic cerebrovascular disease, 42 males and 18 females, admitted to Lintong Convalescent Hospital of Lanzhou Military Area Command of Chinese PLA between January 2006 and December 2006 were involved in the patient group. They met the diagnosis criteria of ischemic cerebrovascular disease constituted by the 4th Cerebrovascular Disease Conference in 1996, and were confirmed to suffer from ischemic cerebrovascular disease by skull CT and MRI. Another 20 subjects who received healthy examination concurrently in the same hospital, 12 males and 8 females, were involved in the control group. Informed consents of detected items were obtained from involved subjects. METHODS: The plaque thickness of mid portion, distal end and crotch of common carotid artery (CCA), internal carotid artery (ICA), external carotid artery (ECA) and vertebral artery (VA) of involved subjects, who received health examination was separately detected with color Doppler ultrasonograph (HDI-5000). Then, total integral of plaque was calculated. The intima-media thickness (IMT) was measured with two-dimensional ultrasonography. The inner diameter stenosis degree of subjects who had plaque was measured. Blood flow parameters were recorded, and stenosis degree and plaque area were calculated. Blood flow volume of bilateral carotid artery and VA was separately measured with ultrasound equipment software, and brain blood flow volume was calculated. MAIN OUTCOME MEASURES: Atherosclerotic degree and blood flow volume of patients of two groups. RESULTS: Sixty patients with ischemic cerebrovascular disease and twenty subjects who received health examination participated in the final analysis. ①The IMT thickness, total plaque score, and total plaque area of patient group was significantly superior to that of control group, respectively(t=5.216–10.158,P < 0.05). ② There were significant differences in the stenosis degree of CCA, ICA and VA between patient group and control group (t=6.720–12.816,P < 0.05). ③ The blood flow volume of CCA, ICA, VA and brain of patient group was significantly lower than that of control group, respectively (t=2.872–10.860, P < 0.05). CONCLUSION: Ischemic cerebrovascular disease patients have different degrees of changes in atherosclerosis and arterial blood flow.Li Gu Yaqin Feng Liwen Liu Liping Yang Lili He 2007Neural Regeneration Research2007,2,7:7
14Enhanced Vitamin C Production Mediated by an ABA-Induced PTP-like Nucleotidase Improves Plant Drought Tolerance in Arabidopsis and Maize显示文摘Abscisic acid(ABA)is a key phytohormone that mediates environmental stress responses.Vitamin C,or L-ascorbic acid(AsA),is the most abundant antioxidant protecting against stress damage in plants.How the ABA and AsA signaling pathways interact in stress responses remains elusive.In this study,we characterized the role of a previously unidentified gene,PTPN(PTP-like Nucleotidase)in plant drought tolerance.In Arabidopsis,(AtPTPN was expressed in multiple tissues and upregulated by ABA and drought treatments.Loss-of-function mutants oiAtPTPN were hyposensitive to ABA but hypersensitive to drought stresses,whereas plants with enhanced expression AtPTPN showed opposite phenotypes to.Overexpression of maize PTPN(ZmPTPN)promoted,while knockdown oiZmPTPN inhibited plant drought tolerance,indicating conserved and positive roles of PTPN in plant drought tolerance.We found that both AtPTPN and ZmPTPN release Pi by hydrolyzing GDP/GMP/dGMP/IMP/dIMP,and that AtPTPN positively regulated AsA production via endogenous Pi content control.Consistently,overexpression of VTC2,the rate-limiting synthetic enzyme in AsA biosynthesis,promoted AsA production and plant drought tolerance,and these effects were largely dependent on AtPTPN activity.Furthermore,we demonstrated that the heat shock transcription factor HSFA6a directly binds the AtPTPN promoter and activates AtPTPN expression.Genetic analyses showed that AtPTPN is required for HSFA6a to regulate ABA and drought responses.Taken together,our data indicate that PTPN-mediated crosstalk between the ABA signaling and AsA biosynthesis pathways positively controls plant drought tolerance.Hui Zhang Yanli Xiang Neng He Xiangguo Liu Hongbo Liu Liping Fang Fei Zhang Xiaopeng Sun Delin Zhang Xingwang Li William Terzaghi Jianbing Yan Mingqiu Dai 2020Molecular Plant2020,13,5:7
15Desulfurization kinetics of ZnO sorbent loaded on semi-coke support for hot coal gas显示文摘Zn-based sorbent (Z20SC) prepared through semi-coke support in 20 wt% zinc nitrate solution by high-pressure impregnation presents an excellent desulfurization capacity in hot coal gas,in which H2 S can not be nearly detected in the outlet gas before 20 h breakthrough time.The effects of the main operational conditions and the particle size of Z20SC sorbent on its desulfurization performances sorbent were investigated in a fixed-bed reactor and the desulfurization kinetics of Z20SC sorbent removing H2 S from hot coal gas was calculated based on experimental data.Results showed that the conversion of Z20SC sorbent desulfurization reaction increased with the decrease of the particle size of the sorbent and the increases of gas volumetric flow rate,reaction temperature and H 2 S content in inlet gas.Z20SC sorbent obtained from hydrothermal synthesis by high-pressure impregnation possessed much larger surface area and pore volume than semi-coke support,and they were significantly reduced after the desulfurization reaction.The equivalent grain model was reasonably used to analyze experimental data,in which k s=4.382×10-3 exp(-8.270×103/RgT) and Dep=1.262×10-4exp(1.522×104/RgT).It suggests that the desulfurization reaction of the Z20SC sorbent is mainly controlled by the chemical reaction in the initial stage and later by the diffusion through the reacted sorbent layer.Zhiwei Ma Xianrong Zheng Liping Chang Ruiyuan He Weiren Bao 2012Journal of Natural Gas Chemistry2012,21,5:7
16Safety Assessment for a Side-by-side Offloading Mooring System显示文摘In order to improve the safety properties of an offloading system with side-by-side (SBS) mooring in which the FPSO is moored by a yoke system in the field of BZ25-1, it is necessary to analyze those properties. According to the experience of similar projects, tow strategies of different offloading arrangements were discussed by using the 3-D radiation/diffraction theory and quasi-static time domain method to assess their respective safety properties. Through the safety assessment analysis of different arrangement comparisons, various ways to improve the safety properties of offloading systems with side-by-side mooring were verified by analyzing the tension in the mooring lines and the fender deflection. Through comparison it can be concluded that by enlarging the key factors properly, including the size of the fenders and the hawsers as well as the number of hawsers, a better safety performance can be achieved.Liping Sun Qiang He Shangmao Ai 2011Journal of Marine Science and Application2011,10,3:6
17Hepatitis C Virus Infection Downregulates the Ligands of the Activating Receptor NKG2D显示文摘Natural killer (NK) cells are a major component of the host innate immune defense against various pathogens. Several viruses, including hepatitis C virus (HCV), have developed strategies to evade the NK-cell response. In our study, we found HCV infection could trigger DNA damage response by both ataxia telangiectasia mutated (ATM) and ATM- and Rad3-related (ATR) pathways. Recent reports had revealed that NKG2D ligands (NK cell-activating ligands) were upregulated when a major DNA damage checkpoint pathway was activated. However, here we found that DNA damage response was activated but NKG2D ligands were downregulated upon HCV infection. Further studies showed that the protease NS3/4A of HCV which had been shown relation with immune invasion contributed to the reduced expression of NKG2D ligands. These findings provide a novel insight into the mechanisms evolved by HCV to escape from the NK cell response.Chaoyang Wen Xiang He Hongfang Ma Ningbo Hou Congwen Wei Ting Song Yanhong Zhang Liping Sun Qingjun Ma Hui Zhong 2008Cellular & Molecular Immunology2008,5,6:6

19The heterogeneity of islet autoantibodies and the progression of islet failure in type 1 diabetic patients显示文摘Type 1 diabetes mellitus is heterogeneous in many facets. The patients suffered from type 1 diabetes present several levels of islet function as well as variable number and type of islet-specific autoantibodies. This study was to investigate prevalence and heterogeneity of the islet autoantibodies and clinical phenotypes of type 1 diabetes mellitus; and also discussed the process of islet failure and its risk factors in Chinese type 1 diabetic patients. A total of 1,291 type 1 diabetic patients were enrolled in this study. Demographic information was collected. Laboratory tests including mixed-meal tolerance test, human leukocyte antigen alleles, hemoglobin A1 c, lipids, thyroid function and islet autoantibodies were conducted. The frequency of islet-specific autoantibody in newly diagnosed T1 DM patients(duration shorter than half year) was 73% in East China. According to binary logistic regressions, autoantibody positivity, longer duration and lower Body Mass Index were the risk factors of islet failure. As the disease developed, autoantibodies against glutamic acid decarboxylase declined as well as the other two autoantibodies against zinc transporter 8 and islet antigen 2. The decrease of autoantibodies was positively correlated with aggressive beta cell destruction. Autoantibodies can facilitate the identification of classic T1 DM from other subtypes and predict the progression of islet failure. As there were obvious heterogeneity in autoantibodies and clinical manifestation in different phenotypes of the disease, we should take more factors into consideration when identifying type 1 diabetes mellitus.Jin Liu Lingling Bian Li Ji Yang Chen Heng Chen Yong Gu Bingqin Ma Wei Gu Xinyu Xu Yun Shi Jian Wang Dalong Zhu Zilin Sun Jianhua Ma Hui Jin Xing Shi Heng Miao Bing Xin Yan Zhu Zhenwen Zhang Ruifang Bu Lan Xu Guangde Shi Wei Tang Wei Li Dongmei Zhou Jun Liang Xingbo Cheng Bimin Shi Jixiang Dong Ji Hu Chen Fang Shao Zhong Weinan Yu Weiping Lu Chenguang Wu Li Qian Jiancheng Yu Jialin Gao Xiaoqiang Fei Qingqing Zhang Xueqin Wang Shiwei Cui Jinluo Cheng Ning Xu Guofeng Wang Guoqing Han Chunrong Xu Yun Xie Minmin An Wei Zhang Zhixiao Wang Yun Cai Qi Fu Yu Fu Shuai Zheng Fan Yang Qingfang Hu Hao Dai Yu Jin Zheng Zhang Kuanfeng Xu Yifan Li Jie Shen Hongwen Zhou Wei He Xuqin Zheng Xiao Han Liping Yu Jinxiong She Mei Zhang Tao Yang 2016Science China(Life Sciences)2016,59,9:5
20LRP6 downregulation promotes cardiomyocyte proliferation and heart regeneration显示文摘The adult mammalian heart is thought to be a terminally differentiated organ given the postmitotic nature of cardiomyocytes.Consequently,the potential for cardiac repair through cardiomyocyte proliferation is extremely limited.Low-density lipoprotein receptor-related protein 6(LRP6)is a Wnt co-receptor that is required for embryonic heart development.In this study we investigated the role of LRP6 in heart repair through regulation of cardiomyocyte proliferation.Lrp6 deficiency increased cardiomyocyte cell cycle activity in neonatal,juvenile and adult mice.Cardiomyocyte-specific deletion of Lrp6 in the mouse heart induced a robust regenerative response after myocardial infarction(MI),led to reduced MI area and improvement in left ventricular systolic function.In vivo genetic lineage tracing revealed that the newly formed cardiomyocytes in Lrp6-deficient mouse hearts after MI were mainly derived from resident cardiomyocytes.Furthermore,we found that the pro-proliferative effect of Lrp6 deficiency was mediated by the ING5/P21 signaling pathway.Gene therapy using the adeno-associated virus(AAV)9 miRNAi-Lrp6 construct promoted the repair of heart injury in mice.Lrp6 deficiency also induced the proliferation of human induced pluripotent stem cell-derived cardiomyocytes(iPSC-CMs).Our study identifies LRP6 as a critical regulator of cardiomyocyte proliferation,which may lead to the development of a novel molecular strategy to promote myocardial regeneration and repair.Yahan Wu Liping Zhou Hongyu Liu Ran Duan Huixing Zhou Fulei Zhang Xiaoyu He Dongbo Lu Ke Xiong Maolin Xiong Jinzhu Zhuang Yi Liu Li Li Dandan Liang Yi-Han Chen 2021Cell Research2021,31,4:5
