| 1 | Epigenetic changes associated with oocyte aging显示文摘It is well established that the decline in female reproductive outcomes is related to postovulatory aging of oocytes and advanced maternal age.Poor oocyte quality is correlated with compromised genetic integrity and epigenetic changes during the oocyte aging process.Here,we review the epigenetic alterations,mainly focused on DNA methylation,histone acetylation and methylation associated with postovulatory oocyte aging as well as advanced maternal age.Furthermore,we address the underlying epigenetic mechanisms that contribute to the decline in oocyte quality during oocyte aging. | SCHATTEN Heide MA JunYu SCHATTEN Heide SUN QingYuan | 2012 | Science China(Life Sciences)2012，55，8： | 16 |
| 2 | Humoral immune response to circulating SARS-CoV-2 variants elicited by inactivated and RBD-subunit vaccines显示文摘SARS-CoV-2 variants could induce immune escape by mutations on the receptor-binding domain(RBD)and N-terminal domain(NTD).Here we report the humoral immune response to circulating SARS-CoV-2 variants,such as 501Y.V2(B.1.351),of the plasma and neutralizing antibodies(NAbs)elicited by CoronaVac(inactivated vaccine),ZF2001(RBD-subunit vaccine)and natural infection.Among 86 potent NAbs identified by high-throughput single-cell VDJ sequencing of peripheral blood mononuclear cells from vaccinees and convalescents,near half anti-RBD NAbs showed major neutralization reductions against the K417N/E484K/N501Y mutation combination,with E484K being the dominant cause.VH3-53/VH3-66 recurrent antibodies respond differently to RBD variants,and K417N compromises the majority of neutralizing activity through reduced polar contacts with complementarity determining regions.In contrast,the 242–244 deletion(242–244Δ)would abolish most neutralization activity of anti-NTD NAbs by interrupting the conformation of NTD antigenic supersite,indicating a much less diversity of anti-NTD NAbs than anti-RBD NAbs.Plasma of convalescents and CoronaVac vaccinees displayed comparable neutralization reductions against pseudo-and authentic 501Y.V2 variants,mainly caused by E484K/N501Y and 242–244Δ,with the effects being additive.Importantly,RBD-subunit vaccinees exhibit markedly higher tolerance to 501Y.V2 than convalescents,since the elicited anti-RBD NAbs display a high diversity and are unaffected by NTD mutations.Moreover,an extended gap between the third and second doses of ZF2001 leads to better neutralizing activity and tolerance to 501Y.V2 than the standard three-dose administration.Together,these results suggest that the deployment of RBD-vaccines,through a third-dose boost,may be ideal for combating SARS-CoV-2 variants when necessary,especially for those carrying mutations that disrupt the NTD supersite. | Yunlong Cao Ayijiang Yisimayi Yali Bai Weijin Huang Xiaofeng Li Zhiying Zhang Tianjiao Yuan Ran An Jing Wang Tianhe Xiao Shuo Du Wenping Ma Liyang Song Yongzheng Li Xiang Li Weiliang Song Jiajing Wu Shuo Liu Xuemei Li Yonghong Zhang Bin Su Xianghua Guo Yangyang Wei Chuanping Gao Nana Zhang Yifei Zhang Yang Dou Xiaoyu Xu Rui Shi Bai Lu Ronghua Jin Yingmin Ma Chengfeng Qin Youchun Wang Yingmei Feng Junyu Xiao Xiaoliang Sunney Xie | 2021 | Cell Research2021，31，7： | 12 |
| 3 | An effective strategy to establish a male sterility mutant mini-library by CRISPR/Cas9-mediated knockout of anther-specific genes in rice显示文摘Male sterility(MS),characterized by functional defects in male organs or gametes,is an important agronomic trait for hybrid seed production,especially for self-pollinated crops such as rice(Oryza sativa L)(Chen and Liu,2014).Spontaneous MS mutants are rare and difficult to maintain in nature,thus limiting basicresearch and breeding.Artificial mutants are typically generated by physical,chemical,or biological mutagenesis(Wei et al,2013).Recently developed genome editing systems such as CRISPR/Cas9 allow efficient and timesaving knockout of endogenous genes at specific sites(Smith et al,2000;Moscou and Bogdanove,2009;Gasiunas et al.,2012). | Kun Ma Jingluan Han Yu Hao Zhongfang Yang Junyu Chen Yao-Guang Liu Qinlong Zhu Letian Chen | 2019 | Journal of Genetics and Genomics2019，46，5： | 6 |
| 4 | A robust soc-MOF platform exhibiting high gravimetric uptake and volumetric deliverable capacity for on-board methane storage显示文摘Emerging as an outperformed class of metal-organic frameworks(MOFs),square-octahedron(soc)topology MOFs(soc-MOFs)feature superior properties of high porosity,large gas storage capacity,and excellent thermal/chemical stability.We report here an iron based soc-MOF,denoted as Fe-pbpta(H4pbpta=4,4',4'',4'''-(1,4-phenylenbis(pyridine-4,2-6-triyl))-tetrabenzoic acid)possessing a very high Brunauer,Emmett and Teller(BET)surface area of 4,937 m2/g and a large pore volume of 2.15 cm3/g.The MOF demonstrates by far the highest gravimetric uptake of 369 cm3(STP)/g under the DOE operational storage conditions(35 bar and 298 K)and a high volumetric deliverable capacity of 192 cc/cc at 298 K and 65 bar.Furthermore,Fe-pbpta exhibits high thermal and aqueous stability making it a promising candidate for on-board methane storage. | Gaurav Verma Sanjay Kumar Harsh Vardhan Junyu Ren Zheng Niu Tony Pham Lukasz Wojtas Sydney Butikofer Jose C Echeverria Garcia Yu-Sheng Chen Brian Space and Shengqian Ma | 2021 | Nano Research2021，14，2： | 2 |
| 5 | Efficiency of cotton bollworm (Helicoverpa armigera Hübner) control of different Bt cotton varieties in North China显示文摘Background: The cotton bollworm(Helicoverpa armigera) is one of cotton's most destructive insect pests in terms of yield and quality. Since 1997, China has grown commercially available transgenic Bacillus thuringiensis(Bt) cotton. We aimed to investigate the variation in resistance of transgenic Bt cotton varieties to cotton bollworm in North China.Methods: Populations of cotton bollworm were monitored from 2008 to 2015 in environments where Bt cotton was planted adjacent to other non-Bt crops. The study included 197 Bt cotton varieties planted in 42 counties/locations in three provinces(Hebei, Shandong and Henan) of North China, which were evaluated through field investigations,bioassays, and enzyme-linked immunosorbent assays(ELISA).Results: The average number of cotton bollworms never exceeded the action threshold(10 larvae per 100 cotton plants), however, their number reached 19.55 per 100 cotton plants in 2011. The ratios of damaged plants to total Bt cotton stem-tips, buds, and bolls was low except in 2010, when the ratios reached 1.82%, 2.09%, and 10.63%,respectively. The results of bioassay showed that the corrected mortality were higher at the second generation cotton bollworm stage than the third and fourth germination stages. Totally, Bt protein content declined sharply at the seedling stage from 2008 to 2015.Conclusions: This study indicated that almost all Bt cotton varieties were capable to effectively control the populations of cotton bollworm in North China. | Lü Limin LUO Junyu ZHANG Shuai YU Qianlin MA Ligang LIU Xiaofeng WANG Chunyi MA Xiaoyan MA Yan CUI Jinjie | 2018 | Journal of Cotton Research2018，1，1： | 1 |
| 6 | The influence of genetic polymorphisms in drug metabolism enzymes and transporters on the pharmacokinetics of different fluvastatin formulations显示文摘The purpose of the present study was to investigate the impact of genetic polymorphism on fluvastatin pharmacokinetics.In addition,we compared the fluvastatin pharmacokinetics differences between extended-release(ER)80 mg tablet and immediate-release(IR)40 mg capsule in terms of drug metabolism enzyme and transporter genetic polymorphisms.In this open-label,randomized,two-period,two-treatment,crossover study(n=24),effects of ABCG2,SLCO1B1,ABCB1,CYP2C9 and CYP3A5 polymorphisms on the pharmacokinetics of fluvastatin were analyzed.The administration dosage for IR 40 mg and ER 80 mg were twice and once daily,respectively,for total 7 d.Blood samples for pharmacokinetic evaluation were taken on the 1st and 7th d.The lower exposure following ER was observed.For ER tablets,SLCO1B1 T521C genotype correlated with AUC 0-24 of repeat doses(P=0.010).SLCO1B1 T521C genotype had no statistically significant effect on AUC 0-24 of IR capsule of fluvastatin after single or repeated doses.In vitro study demonstrated that when the concentration of fluvastatin was low(<1μmol/l),the uptake of fluvastatin in the HEK293-OATP1B1 with SLCO1B1521TT(K m=0.18μmol/l)was faster than that with SLCO1B1521CC(K m=0.49μmol/l),On the other hand,when concentration reached to higher level(>1μmol/l),transport velocity of fluvastatin by HEK293-OATP1B1 with SLCO1B1521TT(K m=11.4μmol/l)and with SLCO1B1521TCC(K m=15.1μmol/l)tend to be the same.It suggests that the increased effect of SLCO1B1 T521C genotype on ER formulation of fluvastatin was mainly caused by lower blood concentrations.We recommend that formulation should be incorporated into future pharmacogenomics studies. | Qian Xiang Weidang Wu Nan Zhao Chuan Li Junyu Xu Lingyue Ma Xiaodan Zhang Qiufen Xie Zhuo Zhang Jiancheng Wang Weiren Xu Xia Zhao Yimin Cui | 2020 | Asian Journal of Pharmaceutical Sciences2020，15，2： | 1 |

| 8 | Engineering organoid microfluidic system for biomedical and health engineering:A review显示文摘In recent years,organoid technology,i.e.,in vitro three-dimensional(3D)tissue culture,has attracted increasing attention in biomedical engineering.Organoids are cell complexes induced by differentiation of stem cells or organ-progenitor cells in vitro using 3D culture technology.They can replicate the key structural and functional characteristics of the target organs in vivo.With the opening up of this new field of health engineering,there is a need for engineering-system approaches to the production,control,and quantitative analysis of organoids and their microenvironment.Traditional organoid technology has limitations,including lack of physical and chemical microenvironment control,high heterogeneity,complex manual operation,imperfect nutritional supply system,and lack of feasible online analytical technology for the organoids.The introduction of microfluidic chip technology into organoids has overcome many of these limitations and greatly expanded the scope of applications.Engineering organoid microfluidic system has become an interdisciplinary field in biomedical and health engineering.In this review,we summarize the development and culture system of organoids,discuss how microfluidic technology has been used to solve the main technical challenges in organoid research and development,and point out new opportunities and prospects for applications of organoid microfluidic system in drug development and screening,food safety,precision medicine,and other biomedical and health engineering fields. | Yifan Xing Junyu Liu Xiaojie Guo Haipeng Liu Wen Zeng Yi Wang Chong Zhang Yuan Lu Dong He Shaohua Ma Yonghong He Xin-Hui Xing | 2021 | Chinese Journal of Chemical Engineering2021，34，2： | 1 |

| 10 | Deactivation of Cu-SAPO-34 by urea-related deposits at low temperatures and the regeneration显示文摘Selective catalytic reduction(SCR) with urea catalyzed by Cu-SAPO-34 is an effective method to eliminate NO_x from diesel exhaust. However, urea-related deposits may form during cold-start and urban driving due to low exhaust temperatures. The activity of CuSAPO-34 at 175°C is significantly degraded by urea exposure, and 300°C is required for regeneration. Through in-situ diffuse reflectance infrared Fourier transform spectroscopy(DRIFTS) and temperature-programmed hydrolysis studies, the dominant stable deposit at 175°C is identified as biuret, which can be eliminated at 300°C. The urea-derived deactivation and regeneration mechanisms of Cu-SAPO-34 were compared with those of anatase-supported catalysts. | Yue Ma Xiaodong Wu Junyu Zhang Rui Ran Zhichun Si Duan Weng | 2019 | Journal of Environmental Sciences2019，31，7： | 1 |
| 11 | Utilization of cationic microporous metal-organic framework for efficient Xe/Kr separation显示文摘The separation of xenon/krypton(Xe/Kr)mixtures plays a vital role in the industrial process of manufacturing high-purity xenon.Compared with energy-intensive cryogenic distillation,porous materials based on physical adsorption are very promising in the low-cost and energy-saving separation processes.Herein,we show that a cationic metal-organic framework(named as FJU-55)exhibits highly efficient Xe/Kr separation performance,which can be attributable to its uniform three-dimensional(3D)interconnection channels and the electro-positive features as the host framework.Moreover,FJU-55 demonstrates good Xe adsorption capacity of 1.41 mmol/g and excellent Xe/Kr selectivity of 10(298 K and 100 kPa),together with a high Qst value of 39.4 kJ/mol at low coverage area.The superior Xe/Kr separation performance of FJU-55 was further confirmed by the dynamic breakthrough experiments.Results obtained via molecular modeling studies have revealed that the suitable pore size and abundant accessible aromatic ligands in FJU-55 could offer strong multiple C–H∙∙∙Xe interactions,which play a collaborative role in this challenging gas separation task. | Lingshan Gong Ying Liu Junyu Ren Abdullah MAl-Enizi Ayman Nafady Yingxiang Ye Zongbi Bao Shengqian Ma | 2022 | Nano Research2022，15，8： | 1 |

| 13 | Consensus on potential biomarkers developed for use in clinical tests for schizophrenia显示文摘Background Schizophrenia is a serious mental illness affecting approximately 20 million individuals globally.Both genetic and environmental factors contribute to the illness.If left undiagnosed and untreated,schizophrenia results in impaired social function,repeated hospital admissions,reduced quality of life and decreased life expectancy.Clinical diagnosis largely relies on subjective evidence,including self-reported experiences,and reported behavioural abnormalities followed by psychiatric evaluation.In addition,psychoses may occur along with other conditions,and the symptoms are often episodic and transient,posing a significant challenge to the precision of diagnosis.Therefore,objective,specific tests using biomarkers are urgently needed for differential diagnosis of schizophrenia in clinical practice.Aims We aimed to provide evidence-based and consensus-based recommendations,with a summary of laboratory measurements that could potentially be used as biomarkers for schizophrenia,and to discuss directions for future research.Methods We searched publications within the last 10 years with the following keywords:‘schizophrenia’,‘gene’,‘inflammation’,‘neurotransmitter’,‘protein marker’,‘gut microbiota’,‘pharmacogenomics’and‘biomarker’.A draft of the consensus was discussed and agreed on by all authors at a round table session.Results We summarised the characteristics of candidate diagnostic markers for schizophrenia,including genetic,inflammatory,neurotransmitter,peripheral protein,pharmacogenomic and gut microbiota markers.We also proposed a novel laboratory process for diagnosing schizophrenia in clinical practice based on the evidence summarised in this paper.Conclusions Further efforts are needed to identify schizophrenia-specific genetic and epigenetic markers for precise diagnosis,differential diagnosis and ethnicity-specific markers for the Chinese population.The development of novel laboratory techniques is making it possible to use these biomarkers clinically to diagnose disease. | Ping Lin Junyu Sun Xiaoyan Lou Dan Li Yun Shi Zhenhua Li Peijun Ma Ping Li Shuzi Chen Weifeng Jin Shuai Liu Qing Chen Qiong Gao Lili Zhu Jie Xu Mengyuan Zhu Mengxia Wang Kangyi Liang Ling Zhao Huabin Xu Ke Dong Qingtian Li Xunjia Cheng Jinghong Chen Xiaokui Guo | 2022 | General Psychiatry2022，35，1： | 1 |
| 14 | Overview of Studies on Financial Support for China's Agricultural Industrialization显示文摘Agricultural industrialization is an innovative operation mode and effective drive for transformation of traditional agriculture to modern agriculture. Benign development of agricultural industrialization depends on financial support. With increase of the function of financial support for agricultural industrialization development,academic circles have made deeper and deeper researches on agricultural industrialization. These researches mainly touch upon four aspects:( i) definition of concept of financial support for agricultural industrialization;( ii)functions of financial support for agricultural industrialization;( iii) existing problems in financial support for agricultural industrialization and problem causes;( iv) specific recommendations of promotion of financial support for agricultural industrialization development. Although existing researches are already extensive and some common understandings have been reached,there are still some research gaps and weak points,and it needs further researches. | Junyu MIAO Junqi MA Jingyao TANG | 2014 | Asian Agricultural Research2014，6，11： | 1 |
| 15 | Synergistic Combination of Biodegradable Peptide Polymer and Curcumin as Promising Antibiotic Substitution in Aquaculture to Alleviate the Global Challenge of Antimicrobial Resistance显示文摘The massive use of antibiotics in aquaculture and resulted antibacterial resistance problem urgently need antibiotic substitutions. Herein, we report a promising substitution of aquaculture antibiotics using a synergistic combination of biodegradable peptide polymers and curcumin, a natural compound from plant. The synergistic combination shows strong antibacterial activity against V. fluvialis and some other common bacteria in aquaculture. The membrane-damaging antibacterial mechanism echoes our finding that the synergistic combination will not induce bacteria to develop resistance after continuous use. The synergistic combination also displays effective cure on V. fluvialis-infected zebrafish. The biodegradability of the peptide polymer enables the combination to lose antibacterial activity and will not cause selective pressure on bacterial in the environment. Our study indicates potential application of synergistic composition, biodegradable peptide polymer and curcumin, as promising antibiotic substitution in aquaculture, which represents a promising strategy to address the global challenge of antimicrobial resistance. | Pengcheng Ma Yuan Chen Ning Shao Junyu Zhang Yueming Wu Runhui Liu | 2022 | Chinese Journal of Chemistry2022，40，24： | 1 |
| 16 | Functional characterization of novel NPRL3 mutations identified in three families with focal epilepsy显示文摘Focal epilepsy accounts for 60% of all forms of epilepsy, but the pathogenic mechanism is not well understood. In this study,three novel mutations in NPRL3(nitrogen permease regulator-like 3), c.937_945del, c.1514dup C and 6,706-bp genomic DNA(g DNA) deletion, were identified in three families with focal epilepsy by linkage analysis, whole exome sequencing(WES) and Sanger sequencing. NPRL3 protein is a component of the GATOR1 complex, a major inhibitor of m TOR signaling. These mutations led to truncation of the NPRL3 protein and hampered the binding between NPRL3 and DEPDC5, which is another component of the GATOR1 complex. Consequently, the mutant proteins enhanced m TOR signaling in cultured cells, possibly due to impaired inhibition of m TORC1 by GATOR1. Knockdown of nprl3 in Drosophila resulted in epilepsy-like behavior and abnormal synaptic development. Taken together, these findings expand the genotypic spectrum of NPRL3-associated focal epilepsy and provide further insight into how NPRL3 mutations lead to epilepsy. | Shiyue Du Sheng Zeng Li Song Hongying Ma Rui Chen Junyu Luo Xu Wang Tingbin Ma Xuan Xu Hao Sun Ping Yi Jifeng Guo Yaling Huang Mugen Liu Tao Wang Wei-Ping Liao Luoying Zhang Jing Yu Liu Beisha Tang | 2023 | Science China(Life Sciences)2023，66，9： | 0 |

| 18 | Mechanisms of PiT2-loop7 Missense Mutations Induced Pi Dyshomeostasis显示文摘PiT2 is an inorganic phosphate(Pi)transporter whose mutations are linked to primary familial brain calcification(PFBC).PiT2 mainly consists of two ProDom(PD)domains and a large intracellular loop region(loop7).The PD domains are crucial for the Pi transport,but the role of PiT2-loop7 remains unclear.In PFBC patients,mutations in PiT2-loop7 are mainly nonsense or frameshift mutations that probably cause PFBC due to C-PD1131 deletion.To date,six missense mutations have been identified in PiT2-loop7;however,the mechanisms by which these mutations cause PFBC are poorly understood.Here,we found that the p.T390A and p.S434W mutations in PiT2-loop7 decreased the Pi transport activity and cell surface levels of PiT2.Furthermore,we showed that these two mutations attenuated its membrane localization by affecting adenosine monophosphate-activated protein kinase(AMPK)-or protein kinase B(AKT)-mediated PiT2 phosphorylation.In contrast,the p.S121C and p.S601W mutations in the PD domains did not affect PiT2 phosphorylation but rather impaired its substrate-binding abilities.These results suggested that missense mutations in PiT2-loop7 can cause Pi dyshomeostasis by affecting the phosphorylation-regulated cell-surface localization of PiT2.This study helps understand the pathogenesis of PFBC caused by PiT2-loop7 missense mutations and indicates that increasing the phosphorylation levels of PiT2-loop7 could be a promising strategy for developing PFBC therapies. | Hao Sun Xuan Xu Junyu Luo Tingbin Ma Jiaming Cui Mugen Liu Bo Xiong Shujia Zhu Jing-Yu Liu | 2023 | Neuroscience Bulletin2023，39，1： | 0 |

| 20 | A new strategy for designing polymer electron acceptors:electronrich conjugated backbone with electron-deficient side units显示文摘Three 'double-cable' conjugated polymers with thienopyrroledione-based backbone and perylene bisimide as side units were designed as electron acceptor for polymer-polymer solar cells. The polymers show broad absorption spectra and low-lying frontier energy levels due to both aromatic backbone and side units. The new double-cable polymers can be used as electron acceptor to combine with several electron donors, in which power conversion efficiencies above 3% could be achieved. | Fan Yang Xiaohui Wang Guitao Feng Junshu Ma Cheng Li Junyu Li Wei Ma Weiwei Li | 2018 | Science China Chemistry2018，61，7： | 0 |
