2Root microbiota shift in rice correlates with resident time in the field and developmental stage显示文摘Land plants in natural soil form intimate relationships with the diverse root bacterial microbiota. A growing body of evidence shows that these microbes are important for plant growth and health. Root microbiota composition has been widely studied in several model plants and crops; however, little is known about how root microbiota vary throughout the plant's life cycle under field conditions. We performed longitudinal dense sampling in field trials to track the time-series shift of the root microbiota from two representative rice cultivars in two separate locations in China. We found that the rice root microbiota varied dramatically during the vegetative stages and stabilized from the beginning of the reproductive stage, after which the root microbiota underwent relatively minor changes until rice ripening. Notably, both rice genotype and geographical location influenced the patterns of root microbiota shift that occurred during plant growth. The relative abundance of Deltaproteobacteria in roots significantly increased overtime throughout the entire life cycle of rice, while that of Betaproteobacteria, Firmicutes, and Gammaproteobacteria decreased. By a machine learning approach, we identified biomarker taxa and established a model to correlate root microbiota with rice resident time in the field(e.g., Nitrospira accumulated from 5 weeks/tillering in field-grown rice). Our work provides insights into the process of rice root microbiota establishment.Jingying Zhang Na Zhang Yong-Xin Liu Xiaoning Zhang Bin Hu Yuan Qin Haoran Xu Hui Wang Xiaoxuan Guo Jingmei Qian Wei Wang Pengfan Zhang Tao Jin Chengcai Chu Yang Bai 2018Science China(Life Sciences)2018,61,6:24
3Field released transgenic papaya effect on soil microbial communities and enzyme activities显示文摘Soil properties, microbial communities and enzyme activities were stud ied in soil amended with replicase (RP)-transgenic or non-transgenic papaya unde r field conditions. Compared with non-transgenic papaya, significant differences (P<0.05) were observed in total nitrogen in soils grown with transgenic papaya. There were also significant differences (P<0.05) in the total number of colony forming units (CFUs) of bacteria, actinomycetes and fungi between soils amended with RP-transgenic plants and non-transgenic plants. Compared with non-transgen ic papaya, the total CFUs of bacteria, actinomycetes and fungi in soil with tran sgenic papaya increased by 0.43—1.1, 0.21—0.80 and 0.46—0.73 times respective ly. Significantly higher (P<0.05) CFUs of bacteria, actinomycetes and fungi res istant to kanamycin (Km) were obtained in soils with RP-transgenic papaya than t hose with non-transgenic papaya in all concentrations of Km. Higher resistance q uotients for Kmr (kanamycin resistant) bacteria, actinomycetes and fungi were fo und in soil planted with RP-transgenic papaya, and the resistance quotients for Kmr bacteria, actinomycetes and fungi in soils with transgenic papaya increased 1.6—4.46, 0.63—2.5 and 0.75—2.30 times. RP-transgenic papaya and non-transg enic papaya produced significantly different enzyme activities in arylsulfatase (5.4—5.9x), polyphenol oxidase (0.7—1.4x), invertase (0.5—0.79x), cellulase ( 0.23—0.35x) and phosphodiesterase (0.16—0.2x). The former three soil enzymes appeared to be more sensitive to the transgenic papaya than the others, and cou ld be useful parameters in assessing the effects of transgenic papaya. Transgen ic papaya could alter soil chemical properties, enzyme activities and microbial communities.WEI Xiang-dong ZOU Hui-ling CHU Lee-min LIAO Bin YE Chang-min LAN Chong-yu 2006Journal of Environmental Sciences2006,18,4:22

5Huoxin Pill(活心丸)Attenuates Cardiac Fibrosis by Suppressing TGF-β1/Smad2/3 Pathway in Isoproterenol-Induced Heart Failure Rats显示文摘Objective:To evaluate the effects of Huoxin Pill(活心丸,HXP)on cardiac fibrosis and heart failure(HF)in isoproterenol(ISO)-induced HF rats.Methods:Thirty Wistar rats were randomly divided into 5 groups including control,HF,isosorbide mononitrate(ISMN),HXP low(HXP-L),and HXP high(HXP-H)groups(n=6 for each group)according to the complete randomization method.Rats were pretreated with ISMN(5 mg/kg daily),low concentration of HXP(10 mg/kg daily)or high concentration of HXP(30 mg/kg daily)or equal volume of saline by intragastric administration for 1 week,followed by intraperitoneal injection of ISO(10 mg/kg,14 days),and continually intragastric administrated with above medicines or saline for additional 6 weeks.The effects of HXP treatment on the cardiac function,heart weight index(HWI),pathological changes,and collagen content were further assessed.Moreover,the role of HXP on activation of transforming growth factor-β1(TGF-β1)/Smads pathway was further explored using immunohistochemistry(IHC)and Westernblot assay.Results:HXP treatment significantly alleviated the decrease of ejection fraction(EF)and fractional shortening(FS),while decreased the elevation of left ventricular end-systolic volume(LVESV)in ISO-induced HF rats(P<0.05).Moreover,HXP treatment obviously attenuated the increase of HWI and serum level of creatine kinase MB(CK-MB,P<0.05),as well as pathological changes in ISO-induced HF rats.Further determination indicated that HXP treatment alleviated the elevation of collagenⅠand collagenⅢprotein expression in cardiac tissues of ISO-induced HF rats.Furthermore,HXP treatment significantly down-regulated the increase of TGF-β1 and p-Smad2/3 protein expression in cardiac tissues of HF rats(P<0.05),while did not affect the expression of total Smad2/3.Conclusions:HXP attenuated heart failure and cardiac fibrosis in ISO-induced HF rats by suppression of TGF-β1/Smad2/3 pathway.PENG Mei-zhong YANG Mei-ling SHEN A-ling ZHOU Xue-ling LU Yan LI Qi SHEN Zhi-qing HUANG Bin PENG Jun CHU Jian-feng 2021Chinese Journal of Integrative Medicine2021,27,6:10
6Oncogenic AURKA-enhanced N6-methyladenosine modification increases DROSHA mRNA stability to transactivate STC1 in breast cancer stem-like cells显示文摘RNase III DROSHA is upregulated in multiple cancers and contributes to tumor progression by hitherto unclear mechanisms.Here,we demonstrate that DROSHA interacts withβ-Catenin to transactivate STC1 in an RNA cleavage-independent manner,contributing to breast cancer stem-like cell(BCSC)properties.DROSHA mRNA stability is enhanced by N6-methyladenosine(m^(6)A)modification which is activated by AURKA in BCSCs.AURKA stabilizes METTL14 by inhibiting its ubiquitylation and degradation to promote DROSHA mRNA methylation.Moreover,binding of AURKA to DROSHA transcript further strengthens the binding of the m^(6)A reader IGF2BP2 to stabilize m^(6)A-modified DROSHA.In addition,wild-type DROSHA,but not an m^(6)A methylation-deficient mutant,enhances BCSC stemness maintenance,while inhibition of DROSHA m^(6)A modification attenuates BCSC traits.Our study unveils the AURKA-induced oncogenic m^(6)A modification as a key regulator of DROSHA in breast cancer and identifies a novel DROSHA transcriptional function in promoting the BCSC phenotype.Fei Peng Jie Xu Bai Cui Qilan Liang Sai Zeng Bin He Hong Zou Manman Li Huan Zhao Yuting Meng Jin Chen Bing Liu Shasha Lv Peng Chu Fan An Zifeng Wang Junxiu Huang Yajing Zhan Yuwei Liao Jinxin Lu Lingzhi Xu Jin Zhang Zhaolin Su Zhiguang Li Fangjun Wang Eric W-FLam Quentin Liu 2021Cell Research2021,31,3:9
7Repeatability and Reproducibility of Quantitative Assessment of the Retinal Microvasculature Using Optical Coherence Tomography Angiography Based on Optical Microangiography显示文摘Objective The aim of this study was to determine the repeatability and reproducibility of optical coherence tomography angiography(OCTA) based on optical microangiography(OMAG) measurements of macular vessels in normal eyes. Methods In this prospective cohort study, 40 eyes of 40 healthy volunteers underwent repeated OCTA(Cirrus HD-OCT 5000 angiography system, Carl Zeiss Meditec, Inc.) scans on two separate visit days. On each visit day, the eyes were scanned three times. The following parameters were used to quantitatively describe the OCTA images of the superficial vascular network: vessel area density(VAD), vessel skeleton density(VSD), vessel diameter index(VDI), vessel perimeter index(VPI), vessel complexity index(VCI), flux, and foveal avascular zone(FAZ). Coefficient of variation(CV) and intraclass correlation coefficient(ICC) were calculated for evaluating intravisit and intervisit repeatability, as well as interobserver reproducibility. Results The measurements showed high repeatability [CVs ≤ 4.2%(intravisit) and ≤ 4.6%(intervisit)] and interobserver reproducibility(ICCs ≥ 0.923) for all parameters. Conclusion This study demonstrated good repeatability and reproducibility of OCTA based on OMAG for the measurement of superficial vessel parameters in normal eyes.ZHAO Qi YANG Wen Li WANG Xiao Na Ruikang K Wang YOU Qi Sheng CHU Zhong Di XIN Chen ZHANG Meng Yu LI Dong Jun WANG Zi Yang CHEN Wei LI Yi Feng CUI Rui SHEN Lin WEI Wen Bin 2018Biomedical and Environmental Sciences2018,31,6:8
8Effects of Heyan Kuntai Capsule(和颜坤泰胶囊)on Follicular Development and Oocyte Cohesin Levels in Aged Mice显示文摘Objective: To evaluate the effect of Heyan Kuntai Capsule(和颜坤泰胶囊, HYKT) on the ovarian function of aged mice and expressions of cohesion complexes in oocytes. Methods: Twenty-five 9-month-old female C57BL/6J mice were randomly divided into 5 groups by block randomization method(n=5 per group), including the control group(saline), 17β-estradiol group [E_2, 100 μg/(kg·d)], and low-, medium-, and highdose of HYKT groups [0.3, 0.9, 2.7 g/(kg·d), respectively]. All mice were treated by intragastric administration for 4 weeks. Hematoxylin and eosin staining and anti-VASA staining were used to detect the amounts of follicles. The apoptosis of follicles was measured by anti-gamma H_2A histone family member X(γH_2AX) staining and Td T-mediated d UTP Nick-End Labeling(TUNEL) assay. The density of cohesin subunits, REC8 meiotic recombination protein(REC8), structural maintenance of chromosome(SMC) 1β and SMC3 in oocytes were evaluated by immunofluorescent staining. Results: After administration of E_2 and high-dose of HYKT, the total number of follicles as well as the number of primordial and primary follicles were significantly increased(P<0.05). Anti-γH_2AX staining and TUNEL assay demonstrated that high-dose of HYKT and E_2 partly suppressed the apoptosis of follicles(P<0.05). Furthermore, it showed an increased trend in the levels of REC8 and SMC1β, after administration with E_2 and HYKT, and no obvious change in the level of SMC3. Conclusion: HYKT could enhance the number of follicles, suppress apoptosis of oocytes and have a trend to elevate the meiotic-specific cohesin subunits(REC8 and SMC1β) in oocytes of aged mice, indicating a beneficial effect on the ovarian function in terms of the quantity and quality of follicles.ZHANG Bin CHU Nan QIU Xue-min TANG Wei Hans-Jorgen Gober LI Da-jin WANG Ling 2018Chinese Journal of Integrative Medicine2018,24,10:7
9Influence of Helicobacter pylori infection on ghrelin levels in children显示文摘AIM:To compare ghrelin levels in plasma and gastric mucosa before and after Helicobacter pylori(H.pylori) treatment in children with H.pylori-associated functional dyspepsia.METHODS:Children with H.pylori-associated functional dyspepsia were enrolled in this study.H.pylori infection was confirmed by positive bacterial culture results.All of the children received triple H.pylori eradication therapy(a 2 wk course of omeprazole,amoxicillin,and clarithromycin).The children were divided into two groups based on the success of the H.pylori treatment:group 1(eradicated)-patients who had a negative 13C-urea breath test 2 mo after the end of therapy;and group 2(non-eradicated)-patients who had a positive 13C-urea breath test.Plasma ghrelin,gastric ghrelin mRNA,and the body mass index were evaluated in both groups before and after the H.pylori treatment.The plasma ghrelin levels were measured by a radioimmunoassay.The expression of gastric ghrelin mRNA was determined by real-time reverse transcription polymerase chain reaction.RESULTS:A total of 50 children with H.pylori-associated functional dyspepsia were treated with triple H.pylori eradication therapy.The mean age of the children was 5.52 ± 0.83 years,and there were 28 males and 22 females.Among the 50 H.pylori-positive children,30 successfully achieved eradication,and 20 did not.The mean plasma ghrelin levels of group 1 were 22.17 ± 1.73 ng/L and 26.59 ± 2.05 ng/L before and after the treatment,respectively,which was a significant increase(P = 0.001).However,the mean plasma ghrelin level of group 2 before and after the H.pylori treatment was 21.34 ± 2.40 ng/L and 22.24 ± 2.10 ng/L(P = 0.785).The plasma ghrelin levels increased substantially after treatment in group 1 but showed only minor changes in group 2.Similarly,the gastric ghrelin mRNA expression in group 1 before treatment was 2.84 ± 0.08.After treatment,the level was 3.11 ± 0.65,which was significantly different(P = 0.023).The gastric ghrelin mRNA expression in group 2 did not change significantly during the treatment(2.82 ± 0.44 vs 2.79 ± 0.31,P = 0.875).The plasma ghrelin and gastric ghrelin mRNA levels in group 1 increased substantially after the treatment but did not do so in group 2.In addition,the body mass index the two groups did not differ significantly 2 mo before and after the H.pylori treatment.CONCLUSION:H.pylori eradication increases the plasma and tissue ghrelin levels in children with H.pylori-associated functional dyspepsia.Zhao-Hui Deng Bo Chu Ya-Zhen Xu Bin Zhang Li-Rong Jiang 2012World Journal of Gastroenterology2012,18,36:7
10Simultaneous preparation of TiO2 and ammonium alum,and microporous SiO2 during the mineral carbonation of titanium-bearing blast furnace slag显示文摘In this study,a route for simultaneous mineralization of CO2 and production of titanium dioxide and ammonium alum,and microporous silicon dioxide from titanium-bearing blast furnace slag(TBBF slag)was proposed,which is comprised of(NH4)2 S04 roasting,acid leaching,ammonium alum crystallization,silicic acid flocculation and Ti hydrolysis.The effects of relevant process parameters were systematically investigated.The re sults showed that under the optimal roasting and leaching conditions about 85%of titanium and 84.6%of aluminum could be extracted while only 30%of silicon entered the leachate.84%of Al^3+was crystallized from the leachate in the form of ammonium aluminum sulfate dodecahydrate with a purity up to 99.5 wt%.About 85%of the soluble silicic acid was flocculated with the aid of secondary alcohol polyoxyethylene ether 9(AEO-9)to yield a microporous SiO2 material(97.4 wt%)from the crystallized mother liquor.The Al-and Si-depleted solution was then hydrolyzed to generate a titanium dioxide(99.1 wt%)with uniform particle size distribution.It was figured out that approximately 146 kg TiO2 could be produced from 1000 kg of TBBF slag.Therefore,the improved process is a promising method for industrial application.Yingjie Xiong Tahani Aldahri Weizao Liu Guanrun Chu Guoquan Zhang Dongmei Luo Hairong Yue Bin Liang Chun Li 2020Chinese Journal of Chemical Engineering2020,28,9:7

12Nitrogen assimilation in plants:current status and future prospects显示文摘Nitrogen(N)is the driving force for crop yields;however,excessive N application in agriculture not only increases production cost,but also causes severe environmental problems.Therefore,comprehensively understanding the molecular mechanisms of N use efficiency(NUE)and breeding crops with higher NUE is essential to tackle these problems.NUE of crops is determined by N uptake,transport,assimilation,and remobilization.In the process of N assimilation,nitrate reductase(NR),nitrite reductase(Ni R),glutamine synthetase(GS),and glutamine-2-oxoglutarate aminotransferase(GOGAT,also known as glutamate synthase)are the major enzymes.NR and Ni R mediate the initiation of inorganic N utilization,and GS/GOGAT cycle converts inorganic N to organic N,playing a vital role in N assimilation and the final NUE of crops.Besides,asparagine synthetase(ASN),glutamate dehydrogenase(GDH),and carbamoyl phosphate synthetase(CPSase)are also involved.In this review,we summarize the function and regulation of these enzymes reported in three major crops—rice,maize,and wheat,also in the model plant Arabidopsis,and we highlight their application in improving NUE of crops via manipulating N assimilation.Anticipated challenges and prospects toward fully understanding the function of N assimilation and further exploring the potential for NUE improvement are discussed.Xiujie Liu Bin Hu Chengcai Chu 2022Journal of Genetics and Genomics2022,49,5:6

14Effect of glial cells on remyelination after spinal cord injury显示文摘Remyelination plays a key role in functional recovery of axons after spinal cord injury.Glial cells are the most abundant cells in the central nervous system.When spinal cord injury occurs,many glial cells at the lesion site are immediately activated,and different cells differentially affect inflammatory reactions after injury.In this review,we aim to discuss the core role of oligodendrocyte precursor cells and crosstalk with the rest of glia and their subcategories in the remyelination process.Activated astrocytes influence proliferation,differentiation,and maturation of oligodendrocyte precursor cells,while activated microglia alter remyelination by regulating the inflammatory reaction after spinal cord injury.Understanding the interaction between oligodendrocyte precursor cells and the rest of glia is necessary when designing a therapeutic plan of remyelination after spinal cord injury.Hai-feng Wang Xing-kai Liu Rui Li Ping Zhang Ze Chu Chun-li Wang Hua-rui Liu Jun Qi Guo-yue Lv Guang-yi Wang Bin Liu Yan Li Yuan-yi Wang 2017Neural Regeneration Research2017,12,10:6
15Microwave-Assisted Synthesis of NiCo_2O_4 Double-Shelled Hollow Spheres for High-Performance Sodium Ion Batteries显示文摘The ternary transitional metal oxide NiCo_2O_4 is a promising anode material for sodium ion batteries due to its high theoretical capacity and superior electrical conductivity. However, its sodium storage capability is severely limited by the sluggish sodiation/desodiation reaction kinetics. Herein, NiCo_2O_4 double-shelled hollow spheres were synthesized via a microwave-assisted, fast solvothermal synthetic procedure in a mixture of isopropanol and glycerol, followed by annealing. Isopropanol played a vital role in the precipitation of nickel and cobalt,and the shrinkage of the glycerol quasi-emulsion under heat treatment was responsible for the formation of the double-shelled nanostructure. The as-synthesized productwas tested as an anode material in a sodium ion battery,was found to exhibit a high reversible specific capacity of 511 m Ahg^(-1) at 100 m Ag^(-1), and deliver high capacity retention after 100 cycles.Xiong Zhang Yanping Zhou Bin Luo Huacheng Zhu Wei Chu Kama Huang 2018Nano-Micro Letters2018,10,1:5
16Archean-Paleoproterozoic Lithospheric Mantle at the Northern Margin of the North China Craton Represented by Tectonically Exhumed Peridotites显示文摘Tectonically emplaced peridotites from North Hebei Province, North China Craton, have retained an original harzburgite mineral assemblage of olivine(54%–58%) + orthopyroxene(40%–46%)+minor clinopyroxene(<1%)+spinel. Samples with boninite-like chemical compositions also coexist with these peridotites. The spinels within the peridotites have high-Al end-members with Al_2O_3 content of 30 wt % –50 wt %, typical of mantle spinels. When compared with experimentally determined melt extraction trajectories, the harzburgites display a high degree of melting and enrichment of SiO_2, which is typical of cratonic mantle peridotites. The peridotites display variably enriched light rare earth elements(REEs), relatively depleted middle REEs and weakly fractionated heavy REEs, which suggest a melt extraction of over 25% in the spinel stability field. The occurrence of arc-and SSZ-type chromian spinels in the peridotites suggests that melt extraction and metasomatism occurred mostly in a subduction-related setting. This is also supported by the geochemical data of the coexisting boninite-like samples. The peridotites have ^(187)Os/^(188)Os ratios ranging from 0.113–0.122, which is typical of cratonic lithospheric mantle. These ^(187)Os/^(188)Os ratios yield model melt extraction ages(TRD) ranging from 981 Ma to 2054 Ma, which may represent the minimum estimation of the melt extraction age. The Al_2O_3-^(187)Os/^(188)Os-proxy isochron ages of 2.4 Ga–2.7 Ga suggest a mantle melt depletion age between the Late Achaean and Early Paleoproterozoic. Both the peridotites and boninite-like rocks are therefore interpreted as tectonically exhumed continental lithospheric mantle of the North China Craton, which has experienced mantle melt depletion and subduction-related mantle metasomatism during the Neoarchean-Paleoproterozoic.TIAN Wei WANG Shuangyue LIU Fenglin CHU Zhuyin WANG Bin CHEN Mimi Jennifer PRICHARD 2017Acta Geologica Sinica(English Edition)2017,91,6:5
17A transceptor-channel complex couples nitrate sensing to calcium signaling in Ambidopsis显示文摘Nitrate-induced Ca^(2+) signaling is crucial for the primary nitrate response in plants.However,the molecular mechanism underlying the generation of the nitrate-specific calcium signature remains unknown.We report here that a cyclic nucleotide-gated channel(CNGC)protein,CNGC15,and the nitrate transceptor(NRT1.1)constitute a molecular switch that controls calcium influx depending on nitrate levels.The expression of CNGC15 is induced by nitrate,and its protein is localized at the plasma membrane after establishment of young seedlings.We found that disruption of CNGC15 results in the loss of the nitrate-induced Ca^(2+) signature(primary nitrate response)and retards root growth,reminiscent of the phenotype observed in the nrt1.1 mutant.We further showed that CNGC15 is an active Ca^(2+)-permeable channel that physically interacts with the NRT1.1 protein in the plasma membrane.Importantly,we discovered that CNGC15-NRT1.1 interaction silences the channel activity of the heterocomplex,which dissociates upon a rise in nitrate levels,leading to reactivation of the CNGC15 channel.The dynamic interactions between CNGC15 and NRT1.1 therefore control the channel activity and Ca^(2+) influx in a nitrate-dependent manner.Our study reveals a new nutrient-sensing mechanism that utilizes a nutrient transceptor-channel complex assembly to couple nutrient status to a specific Ca^(2+) signature.Xiaohan Wang Changxin Feng LiLi Tian Congcong Hou Wang Tian Bin Hu Qian Zhang Zhijie Ren Qi Niu Jiali Song Dongdong Kong Liangyu Liu Yikun He Ligeng Ma Chengcai Chu Sheng Luan Legong Li 2021Molecular Plant2021,14,5:5

20Modulation of nitrate-induced phosphate response by the MYB transcription factor RLI1/HINGE1 in the nucleus显示文摘The coordinated utilization of nitrogen(N)and phosphorus(P)is vital for plants to maintain nutrient balance and achieve optimal growth.Previously,we revealed a mechanism by which nitrate induces genes for phosphate utilization;this mechanism depends on NRT1.1B-facilitated degradation of cytoplasmic SPX4,which in turn promotes cytoplasmic-nuclear shuttling of PHR2,the central transcription factor of phosphate signaling,and triggers the nitrate-induced phosphate response(NIPR)and N-P coordinated utilization in rice.In this study,we unveiled a fine-tuning mechanism of NIPR in the nucleus regulated by Highly Induced by Nitrate Gene 1(HINGE1,also known as RLI1),a MYB-transcription factor closely related to PHR2.RLI1/HINGE1,which is transcriptionally activated by PHR2 under nitrate induction,can directly activate the expression of phosphate starvation-induced genes.More importantly,RLI1/HINGE1 competes with PHR2 for binding to its repressor proteins in the nucleus(SPX proteins),and consequently releases PHR2 to further enhance phosphate response.Therefore,RLI1/HINGE1 amplifies the phosphate response in the nucleus downstream of the cytoplasmic SPX4-PHR2 cascade,thereby enabling fine-tuning of N-P balance when nitrate supply is sufficient.Zhihua Zhang Zhao Li Wei Wang Zhimin Jiang Liping Guo Xiaohan Wang Yangwen Qian Xiahe Huang Yongqiang Liu Xiujie Liu Yahong Liu Aifu Li Yu Yan Junpeng Xie Shouyun Cao Stanislav Kopriva Legong Li Fanjiang Kong Baohui Liu Yingchun Wang Bin Hu Chengcai Chu 2021Molecular Plant2021,14,3:4
