| 2 | The Reference Genome of Tea Plant and Resequencing of 81 Diverse Accessions Provide Insights into Its Genome Evolution and Adaptation显示文摘Tea plant is an important economic crop,which is used to produce the world's oldest and most widely consumed tea beverages.Here,we present a high-quality reference genome assembly of the tea plant(Camellia sinensis var.sinensis)consisting of 15 pseudo-chromosomes.LTR retrotransposons(LTR-RTs)account for 70.38%of the genome,and we present evidence that LTR-RTS play critical roles in genome size expansion and the transcriptional diversification of tea plant genes through preferential insertion in promoter regions and introns.Genes,particularly those coding for terpene biosynthesis pro-teins,associated with tea aroma and stress resistance were significantly amplified through recent tandem duplications and exist as gene clusters in tea plant genome.Phylogenetic analysis of the sequences of 81 tea plant accessions with diverse origins revealed three well-differentiated tea plant populations,support-ing the proposition for the southwest origin of the Chinese cultivated tea plant and its later spread to western Asia through introduction.Domestication and modern breeding left significant signatures on hundreds of genes in the tea plant genome,particularly those associated with tea quality and stress resis-tance.The genomic sequences of the reported reference and resequenced tea plant accessions provide valuable resources for future functional genomics study and molecular breeding of improved cul-tivars of tea plants. | Enhua Xia Wei Tong Yan Hou Yanlin An Linbo Chen Qiong Wu Yunlong Liu Jie Yu Fangdong Li Ruopei Li Penghui Li Huijuan Zhao Ruoheng Ge Jin Huang Ali Inayat Mallano Yanrui Zhang Shengrui Liu Weiwei Deng Chuankui Song Zhaoliang Zhang Jian Zhao Shu Wei Zhengzhu Zhang Tao Xia Chaoling Wei Xiaochun Wan | 2020 | Molecular Plant2020,13,7: | 51 |
| 3 | The Sunway TaihuLight supercomputer: system and applications显示文摘The Sunway Taihu Light supercomputer is the world's first system with a peak performance greater than 100 PFlops. In this paper, we provide a detailed introduction to the Taihu Light system. In contrast with other existing heterogeneous supercomputers, which include both CPU processors and PCIe-connected many-core accelerators(NVIDIA GPU or Intel Xeon Phi), the computing power of Taihu Light is provided by a homegrown many-core SW26010 CPU that includes both the management processing elements(MPEs)and computing processing elements(CPEs) in one chip. With 260 processing elements in one CPU, a single SW26010 provides a peak performance of over three TFlops. To alleviate the memory bandwidth bottleneck in most applications, each CPE comes with a scratch pad memory, which serves as a user-controlled cache. To support the parallelization of programs on the new many-core architecture, in addition to the basic C/C++and Fortran compilers, the system provides a customized Sunway Open ACC tool that supports the Open ACC2.0 syntax. This paper also reports our preliminary efforts on developing and optimizing applications on the Taihu Light system, focusing on key application domains, such as earth system modeling, ocean surface wave modeling, atomistic simulation, and phase-field simulation. | Haohuan FU Junfeng LIAO Jinzhe YANG Lanning WANG Zhenya SONG Xiaomeng HUANG Chao YANG Wei XUE Fangfang LIU Fangli QIAO Wei ZHAO Xunqiang YIN Chaofeng HOU Chenglong ZHANG Wei GE Jian ZHANG Yangang WANG Chunbo ZHOU Guangwen YANG | 2016 | Science China(Information Sciences)2016,59,7: | 45 |
| 4 | Overexpression of p27^(KIP1)induced cell cycle arrest in G_1 phase and subsequent apoptosis in HCC-9204 cell line显示文摘AIM We have previously reported that inducibleover-expression of Bak may prolong cell cycle inG1 phase and lead to apoptosis in HCC-9204 cells.This study is to investigate whether p27KIP1playsan important role in this process.METHODS In order to elucidate the exactfunction of p27KIP1in this process,a zinc induciblep27KIP1stable transfectant and transient p27KIP1-GFP fusion transfectant were constructed.Theeffects of inducible,p27KIP1on cell growth,cellcycle arrest and apoptosis were examined in themock,control pMD vector,and pMD-KIP1transfected HCC-9204 cells.RESULTS This p27KIP1-GFP transfectant maytransiently express the fusion gene.The cellgrowth was reduced by 35% at 48 h of p27KIP1induction with zinc treatment as determined bytrypan blue exclusion assay.These differencesremained the same after 72 h of p27KIP1expression,p27KIP1caused cell cycle arrest after24 h of induction,with 40% increase in G1population.Prolonged p27KIP1expression in thiscell line induced apoptotic cell death reflected byTUNEL assay.Fourty-eight h and 72 h of p27KIP1expression showed a characteristic DNA ladder onagarose gel electrophoresis. CONCLUSION Bak may induce cell cycle arrest inG1 phase through upregulating expression ofp27KIP1and subsequently lead to apoptosis inHCC-9204 cells.The p27KIP1-GFP fusion proteincan be transiently expressed in HCC-9204 cells.The inducible p27KIP1-expressing cell line providesa model to assess p27KIP1function. | Jiang Li Xin Ke Yang Xin Xin Yu Meng Liang Ge Wen Liang Wang Jie Zhang Yun De Hou Department of Pathology,Fourth Military Medical University,Xi’an 710033,Shaanxi Province,China State Key Laboratory for Molecular Virology and Genetic Engineering,Beijing 100052,China Department of Dermatology,Beijing Hospital,Beijing 100016,China Institute of Radiation Medicine,Beijing 100085,China | 2000 | World Journal of Gastroenterology2000,6,4: | 20 |
| 5 | Efficacy and safety of Shexiang Baoxin pill(MUSKARDIA)in patients with stable coronary artery disease:a multicenter,double-blind,placebo-controlled phase IV randomized clinical trial显示文摘Background:The Shexiang Baoxin Pill(MUSKARDIA)has been used for treating coronary artery disease(CAD)and angina for more than 30 years in China.Nevertheless,methodologically sound trials on the use of MUSKARDIA in CAD patients are scarce.The aim of the study is to determine the effects of MUSKARDIA as an add-on to optimal medical therapy(OMT)in patients with stable CAD.Methods:A total of 2674 participants with stable CAD from 97 hospitals in China were randomized 1:1 to a MUSKARDIA or placebo group for 24 months.Both groups received OMT according to local tertiary hospital protocols.The primary outcome was the occurrence of a major adverse cardiovascular event(MACE),defined as a composite of cardiovascular death,non-fatal myocardial infarction(MI),or non-fatal stroke.Secondary outcomes included all-cause mortality,non-fatal MI,non-fatal stroke,hospitalization for unstable angina or heart failure,peripheral revascularization,angina stability and angina frequency.Results:In all,99.7%of the patients were treated with aspirin and 93.0%with statin.After 2 years of treatment,the occurrence of MACEs was reduced by 26.9%in the MUSKARDIA group(MUSKARDIA:1.9%vs.placebo:2.6%;odds ratio=0.80;95%confidence interval:0.45-1.07;P=0.2869).Angina frequency was significantly reduced in the MUSKARDIA group at 18 months(P=0.0362).Other secondary endpoints were similar between the two groups.The rates of adverse events were also similar between the two groups(MUSKARDIA:17.7%vs.placebo:17.4%,P=0.8785).Conclusions:As an add-on to OMT,MUSKARDIA is safe and significantly reduces angina frequency in patients with stable CAD.Moreover,the use of MUSKARDIA is associated with a trend toward reduced MACEs in patients with stable CAD.The results suggest that MUSKARDIA can be used to manage patients with CAD.Trial registration:chictr.org.cn,No.ChiCTR-TRC-12003513. | Jun-Bo Ge Wei-Hu Fan Jing-Min Zhou Hai-Ming Shi Fu-Sui Ji Yang Wu Yu-Lan Zhao Jun Qian Yuan-Zhe Jin Ying-Wu Liu Sheng-Huang Wang Sheng-Hu He Ping Yang Jie Wu Feng Lu Zi-Shan Hou | 2021 | Chinese Medical Journal2021,,2: | 17 |

| 8 | Human carboxylesterases:a comprehensive review显示文摘Mammalian carboxylesterases(CEs) are key enzymes from the serine hydrolase superfamily.In the human body, two predominant carboxylesterases(CES1 and CES2) have been identified and extensively studied over the past decade. These two enzymes play crucial roles in the metabolism of a wide variety of endogenous esters, ester-containing drugs and environmental toxicants. The key roles of CES in both human health and xenobiotic metabolism arouse great interest in the discovery of potent CES modulators to regulate endobiotic metabolism or to improve the efficacy of ester drugs. This review covers the structural and catalytic features of CES, tissue distributions, biological functions, genetic polymorphisms, substrate specificities and inhibitor properties of CES1 and CES2, as well as the significance and recent progress on the discovery of CES modulators. The information presented here will help pharmacologists explore the relevance of CES to human diseases or to assign the contribution of certain CES in xenobiotic metabolism. It will also facilitate medicinal chemistry efforts to design prodrugs activated by a given CES isoform, or to develop potent and selective modulators of CES for potential biomedical applications. | Dandan Wang Liwei Zou Qiang Jin Jie Hou Guangbo Ge Ling Yang | 2018 | Acta Pharmaceutica Sinica B2018,8,5: | 14 |

| 10 | Principle of in-situ 3D rock stress measurement with borehole wall stress relief method and its preliminary applications to determination of in-situ rock stress orientation and magnitude in Jinping hydropower station显示文摘As a main constituent of geological body, the rock masses have distinct differences from other materials, one of which is that rock masses are initially stressed in their natural states. Hence, it is an extremely challenging and significant research project to know the present residual stress of the rock masses in the earth's crust. Although some regularities of distribution of in-situ rock stresses can be deduced, the basic means to study the state of rock stress is in-situ stress measurement. After a brief review of several measuring methods of in-situ 3D rock stress, a new one, borehole wall stress relief method (BWSRM) to determine the in-situ 3D rock stress tensor in a single drilled borehole was proposed. Based on the principle of in-situ rock stress measurement with BWSRM, an original geostress measuring instrument was designed and manufactured. Preliminary experiments for determination of in-situ stress orientation and magnitude were carried out at an experimental tunnel in Jinping Ⅱ hydropower station in China, where the buried depth of overburden was about 2430 m. The results showed that it was feasible to measure the in-situ 3D rock stresses with BWSRM presented in this paper. The BWSRM has a broad prospect for in-situ 3D rock stress measurements in practical rock engineering. | GE XiuRun HOU MingXun | 2012 | Science China(Technological Sciences)2012,55,4: | 12 |
| 11 | Association between Chinese Medicine Therapy and Survival Outcomes in Postoperative Patients with NSCLC: A Multicenter, Prospective, Cohort Study显示文摘Objective:To evaluate the association between Chinese medicine(CM)therapy and disease-free survival(DFS)outcomes in postoperative patients with non-small cell lung cancer(NSCLC).Methods:This multiple-center prospective cohort study was conducted in 13 medical centers in China.Patients with stage I,II,or IDA NSCLC who had undergone radical resection and received conventional postoperative treatment according to the National Comprehensive Cancer Network(NCCN)guidelines were recruited.The recruited patients were divided into a CM treatment group and a control group according to their wishes.Patients in the CM treatment group received continuous CM therapy for more than 6 months or until disease progression.Patients in the control group received CM therapy for less than 1 month.Follow-up was 8nducted over 3 years.The primary outcome was DFS,with recurrence/metastasis rates as a secondary outcome.Results:Between May 2013 and August 2016,503 patients were enrolled into the cohort;266 were classified in the CM treatment group and 237 in the control group.Adjusting for covariates,high exposure to CM was associated with better DFS[hazard ratio(HR)=0.417,95%confidential interval(Cl):0.307-0.567)].A longer duration of CM therapy(6-12 months,12-18 months,>24 months)was associated with lower recurrence and metastasis rates(HR=0.225,0.119 and 0.083,respectively).In a subgroup exploratory analysis,CM therapy was also a protective factor of cancer recurrence and metastasis in both stage n-MA(HR=0.50,95%Cl:0.37-0.67)and stage IDA NSCLC postoperative patients(HR=0.48,95%Cl:0.33-0.71),DFS was even longer among CM treatment group patients.Conclusions:Lon ger duration of CM therapy could be 8nsidered a protective factor of cancer recurrence and metastasis.CM treatment is associated with improving survival outcomes of postoperative NSCLC patients in China. | WANG Xue-qian ZHANG Ying HOU Wei WANG Ying-tian ZHENG Jia-bin LI Jie LIN Li-zhu JIANG Yi-lan WANG Shen-yu XIE Ying ZHANG Hong-liang SHU Qi-jin LI Ping WANG Wei YOU Jian-liang LI Ge LIU Jie FAN Hui-ting ZHANG Mei-ying LIN Hong-sheng | 2019 | Chinese Journal of Integrative Medicine2019,25,11: | 12 |

| 13 | Ursolic acid reduces hepatocellular apoptosis and alleviates alcohol-induced liver injury via irreversible inhibition of CASP3 in vivo显示文摘Alcoholic liver disease (ALD) is one of the pathogenic factors of chronic liver disease with the highest clinical morbidity worldwide. Ursolic acid (UA), a pentacyclic terpenoid carboxylic acid, has shown many health benefits including antioxidative, anti- inflammatory, anticancer, and hepatoprotective activities. We previously found that UA was metabolized in vivo into epoxy- modified UA containing an epoxy electrophilic group and had the potential to react with nucleophilic groups. In this study we prepared an alkynyl-modified UA (AM-UA) probe for tracing and capturing the target protein of UA from liver in mice, then investigated the mode by which UA bound to its target in vivo. By conducting proteome identification and bioinformatics analysis, we identified caspase-3 (CASP3) as the primary target protein of UA associated with liver protection. Molecule docking analysis showed that the epoxy group of the UA metabolite reacted with Cys-163 of CASP3, forming a covalent bond with CASP3. The binding mode of the UA metabolites (UA, CM-UA, and EM-UA) was verified by biochemical evaluation, demonstrating that the epoxy group produced by metabolism played an important role in the inhibition of CASP3. In alcohol-treated HepG2 cells, pretreatment with the UA metabolite (10 μM) irreversibly inhibited CASP3 activities, and subsequently decreased the cleavage of PARP and cell apoptosis. Finally, pre-administration of UA (20–80 mg· kg−1 per day, ig, for 1 week) dose-dependently alleviated alcohol-induced liver injury in mice mainly via the inhibition of CASP3. In conclusion, this study demonstrates that UA is a valuable lead compound for the treatment of ALD. | Xiao-yao Ma Man Zhang Ge Fang Chuan-jing Cheng Mu-kuo Wang Yi-man Han Xiao-tao Hou Er-wei Hao Yuan-yuan Hou Gang Bai | 2021 | Acta Pharmacologica Sinica2021,42,7: | 11 |

| 15 | Graphitic Carbon Quantum Dots Modified Nickel Cobalt Sulfide as Cathode Materials for Alkaline Aqueous Batteries显示文摘Carbon quantum dots(CQDs)as a new class of emerging materials have gradually drawn researchers’concern in recent years.In this work,the graphitic CQDs are prepared through a scalable approach,achieving a high yield with more than 50%.The obtained CQDs are further used as structure-directing and conductive agents to synthesize novel N,S-CQDs/NiCo2S4 composite cathode materials,manifesting the enhanced electrochemical properties resulted from the synergistic effect of highly conductive N,S-codoped CQDs offering fast electronic transport and unique micro-/nanostructured NiCo2S4 microspheres with Faradaic redox characteristic contributing large capacity.Moreover,the nitrogen-doped reduced graphene oxide(N-rGO)/Fe2O3 composite anode materials exhibit ultrahigh specific capacity as well as significantly improved rate property and cycle performance originating from the high-capacity prism-like Fe2O3 hexahedrons tightly wrapped by highly conductive N-rGO.A novel alkaline aqueous battery assembled by these materials displays a specific energy(50.2 Wh kg^−1),ultrahigh specific power(9.7 kW kg^−1)and excellent cycling performance with 91.5%of capacity retention at 3 A g^−1 for 5000 cycles.The present research offers a valuable guidance for the exploitation of advanced energy storage devices by the rational design and selection of battery/capacitive composite materials. | Yirong Zhu Jingying Li Xiaoru Yun Ganggang Zhao Peng Ge Guoqiang Zou Yong Liu Hongshuai Hou Xiaobo Ji | 2020 | Nano-Micro Letters2020,12,2: | 10 |
| 16 | Chemical characteristics of size-resolved aerosols in winter in Beijing显示文摘Size-resolved aerosols were continuously collected by a Nano Sampler for 13 days at an urban site in Beijing during winter 2012 to measure the chemical composition of ambient aerosol particles. Data collected by the Nano Sampler and an ACSM(Aerodyne Aerosol Chemical Speciation Monitor) were compared. Between the data sets,similar trends and strong correlations were observed,demonstrating the validity of the Nano Sampler. PM10 and PM2.5concentrations during the measurement were 150.5 ± 96.0 μg/m3(mean ± standard variation)and 106.9 ± 71.6 μg/m3,respectively. The PM2.5/PM10 ratio was 0.70 ± 0.10,indicating that PM2.5dominated PM10. The aerosol size distributions showed that three size bins of 0.5–1,1–2.5 and 2.5–10 μm contributed 21.8%,23.3% and 26.0% to the total mass concentration(TMC),respectively. OM(organic matter) and SIA(secondary ionic aerosol,mainly SO42-,NO3-and NH4+) were major components of PM2.5. Secondary compounds(SIA and secondary organic carbon) accounted for half of TMC(about 49.8%) in PM2.5,and suggested that secondary aerosols significantly contributed to the serious particulate matter pollution observed in winter. Coal burning,biomass combustion,vehicle emissions and SIA were found to be the main sources of PM2.5. Mass concentrations of water-soluble ions and undetected materials,as well as their fractions in TMC,strikingly increased with deteriorating particle pollution conditions,while OM and EC(elemental carbon) exhibited different variations,with mass concentrations slightly increasing but fractions in TMC decreasing. | Kang Sun Yu Qu Qiong Wu Tingting Han Jianwei Gu Jingjing Zhao Yele Sun Qi Jiang Ziqi Gao Min Hu Yuanhang Zhang Keding Lu Stephan Nordmann Yafang Cheng Li Hou Hui Ge Masami Furuuchi Mitsuhiko Hata Xingang Liu | 2014 | Journal of Environmental Sciences2014,26,8: | 9 |
| 17 | Special AT-rich sequence-binding protein 1 promotes cell growth and metastasis in colorectal cancer显示文摘AIM: To evaluate the expression of special AT-rich sequence-binding protein 1 (SATB1 ) gene in colorectal cancer and its role in colorectal cancer cell proliferation and invasion.METHODS: Immunohistochemistry was used to detect the protein expression of SATB1 in 30 colorectal cancer (CRC) tissue samples and pair-matched adjacent nontumor samples. Cell growth was investigated after enhancing expression of SATB1. Wound-healing assay and Transwell assay were used to investigate the impact of SATB1 on migratory and invasive abilities of SW480 cells in vitro . Nude mice that received subcutaneous implantation or lateral tail vein were used to study the effects of SATB1 on tumor growth or metastasis in vivo . RESULTS: SATB1 was over-expressed in CRC tissues and CRC cell lines. SATB1 promotes cell proliferation and cell cycle progression in CRC SW480 cells. SATB1 over-expression could promote cell growth in vivo . In addition, SATB1 could significantly raise the ability of cell migration and invasion in vitro and promote the ability of tumor metastasis in vivo . SATB1 could up-regulate matrix metalloproteases 2, 9, cyclin D1 and vimentin, meanwhile SATB1 could down-regulate E-cadherin in CRC. CONCLUSION: SATB1 acts as a potential growth and metastasis promoter in CRC. SATB1 may be useful as a therapeutic target for CRC. | Xue-Feng Fang Zhi-Bo Hou Xin-Zheng Dai Cong Chen Jing Ge Hong Shen Xiao-Feng Li Li-Ke Yu Ying Yuan | 2013 | World Journal of Gastroenterology2013,19,15: | 9 |

LAMOST's special design allows both a large aperture (effective aperture of 3.6 m-4.9 m) and a wide field of view (FOV) (5°). It has an innovative active reflecting Schmidt configuration which continuously changes the mirror's surface that adjusts during the observation process and combines thin deformable mirror active optics with segmented active optics. Its primary mirror (6.67m×6.05 m) and active Schmidt mirror (5.74m×4.40 m) are both segmented, and composed of 37 and 24 hexagonal sub-mirrors respectively. By using a parallel controllable fiber positioning technique, the focal surface of 1.75 m in diameter can accommodate 4000 optical fibers. Also, LAMOST has 16 spectrographs with 32 CCD cameras. LAMOST will be the telescope with the highest rate of spectral acquisition. As a national large scientific project, the LAMOST project was formally proposed in 1996, and approved by the Chinese government in 1997. The construction started in 2001, was completed in 2008 and passed the official acceptance in June 2009. The LAMOST pilot survey was started in October 2011 and the spectroscopic survey will launch in September 2012. Up to now, LAMOST has released more than 480 000 spectra of objects. LAMOST will make an important contribution to the study of the large-scale structure of the Universe, structure and evolution of the Galaxy, and cross-identification of multiwaveband properties in celestial objects. | Xiang-Qun Cui Yong-Heng Zhao Yao-Quan Chu Guo-Ping Li Qi Li Li-Ping Zhang Hong-Jun Su Zheng-Qiu Yao Ya-Nan Wang Xiao-Zheng Xing Xin-Nan Li Yong-Tian Zhu Gang Wang Bo-Zhong Gu A-Li Luo Xin-Qi Xu Zhen-Chao Zhang Gen-Rong Liu Hao-Tong Zhang De-Hua Yang Shu-Yun Cao Hai-Yuan Chen Jian-Jun Chen Kun-Xin Chen Ying Chen Jia-Ru Chu Lei Feng Xue-Fei Gong Yong-Hui Hou Hong-Zhuan Hu Ning-Sheng Hu Zhong-Wen Hu Lei Jia Fang-Hua Jiang Xiang Jiang Zi-Bo Jiang Ge Jin Ai-Hua Li Yan Li Ye-Ping Li Guan-QunLiu Zhi-Gang Liu Huo-Ming Shi Zheng-Hong Tang Qing-Sheng Tao Xiang-Yan Yuan Chao Zhai Jing Zhang Yan-Xia Zhang Yong Zhang Ming Zhao Fang Zhou Guo-Hua Zhou Jie Zhu Si-Cheng Zou | 2012 | Research in Astronomy and Astrophysics2012,12,9: | 8 |
| 20 | Genome analysis and signature discovery for diving and sensory properties of the endangered Chinese alligator显示文摘Crocodilians 正在潜水能为时间的长时期在水下面屏息并且是有优秀感觉能力的黄昏的动物的爬行动物。他们包括鸟的一个姐妹系并且没有性染色体。这里,我们报导危及的中国短吻鳄(短吻鳄 sinensis ) 的染色体顺序并且描述它的唯一的特征。下一代的定序产生了未加工的顺序的 314 Gb,产出 2.3 Gb 的一种染色体尺寸。22 200 基因的一个总数用 de novo 在短吻鳄 sinensis 被预言,基于相同、基于 RNA 的联合模型。长潜水的行为的基因基础包括酸式碳酸盐绑定血红素基因,磷酸盐绑定和特殊酸式碳酸盐绑定氧搬运的常规的 co-functioning,和断然选择的精力的复制新陈代谢,铵酸式碳酸盐排泄和心肌收缩。进一步,我们阐明了柔韧的短吻鳄 sinensis 感觉系统包括一个显著地扩展的嗅觉的受体全部剧目,很快演变神经相关的细胞的部件和视觉感觉,和夜里的积极选择视觉相关的视蛋白和健全联系察觉的 otopetrin。我们也为抗菌剂肽的天生的免疫和表示为分成三部分的包含主题的 C 类型 lectin 和 butyrophilin 基因的适应免疫以及扩大与系特定的抗原演讲基因的一个可观的数字发现了一个开发得好的免疫系统。在 situ 杂交的 Multifluorescence 显示出那个短吻鳄染色体 3,它编码 DMRT1,与鸡染色体 Z 一起展出重要 synteny。最后,人口历史分析百万年以前显示了人口混合 0.60-1.05,当 Qinghai 西藏的高原被高举时。 | Qiu-Hong Wan Sheng-Kai Pan Li Hu Ying Zhu Peng-Wei Xu Jin-Quan Xia Hui Chen Gen-Yun He Jing He Xiao-Wei Ni Hao-Long Hou Sheng-Guang Liao Hai-Qiong Yang Ying Chen Shu-Kun Gao Yun-Fa Ge Chang-Chang Cao Peng-Fei Li Li-Ming Fang Li Liao Shu Zhang Meng-Zhen Wang Wei Dong Sheng-Guo Fang | 2013 | Cell Research2013,23,9: | 8 |
