| 1 | Metabolic analyses reveal different mechanisms of leaf color change in two purple-leaf tea plant (Camellia sinensis L.) cultivars显示文摘Purple-leaf tea plants,as anthocyanin-rich cultivars,are valuable materials for manufacturing teas with unique colors or flavors.In this study,a new purple-leaf cultivar“Zixin”(“ZX”)was examined,and its biochemical variation and mechanism of leaf color change were elucidated.The metabolomes of leaves of“ZX”at completely purple,intermediately purple,and completely green stages were analyzed using ultra-performance liquid chromatography quadrupole time of flight mass spectrometry(UPLC-QTOF-MS).Metabolites in the flavonoid biosynthetic pathway remained at high levels in purple leaves,whereas intermediates of porphyrin and chlorophyll metabolism and carotenoid biosynthesis exhibited high levels in green leaves.In addition,fatty acid metabolism was more active in purple leaves,and steroids maintained higher levels in green leaves.Saponin,alcohol,organic acid,and terpenoid-related metabolites also changed significantly during the leaf color change process.Furthermore,the substance changes between“ZX”and“Zijuan”(a thoroughly studied purple-leaf cultivar)were also compared.The leaf color change in“Zijuan”was mainly caused by a decrease in flavonoids/anthocyanins.However,a decrease in flavonoids/anthocyanins,an enhancement of porphyrin,chlorophyll metabolism,carotenoid biosynthesis,and steroids,and a decrease in fatty acids synergistically caused the leaf color change in“ZX”.These findings will facilitate comprehensive research on the regulatory mechanisms of leaf color change in purple-leaf tea cultivars. | Jiazhi Shen Zhongwei Zou Xuzhou Zhang Lin Zhou Yuhua Wang Wanping Fang Xujun Zhu | 2018 | Horticulture Research2018,5,1: | 22 |
| 2 | Repurposing vitamin D for treatment of human malignancies via targeting tumor microenvironment显示文摘Tumor cells along with a small proportion of cancer stem cells exist in a stromal microenvironment consisting of vasculature, cancer-associated fibroblasts, immune cells and extracellular components.Recent epidemiological and clinical studies strongly support that vitamin D supplementation is associated with reduced cancer risk and favorable prognosis. Experimental results suggest that vitamin D not only suppresses cancer cells, but also regulates tumor microenvironment to facilitate tumor repression. In this review, we have outlined the current knowledge on epidemiological studies and clinical trials of vitamin D. Notably, wesummarized and discussed the anticancer action of vitamin D in cancer cells, cancer stem cells and stroma cells in tumor microenvironment, providing a better understanding of the role of vitamin D in cancer. We presently re-propose vitamin D to be a novel and economical anticancer agent. | Xu Wu Wei Hu Lan Lu Yueshui Zhao Yejiang Zhou Zhangang Xiao Lin Zhang Hanyu Zhang Xiaobing Li Wanping Li Shengpeng Wang Chi Hin Cho Jing Shen Mingxing Li | 2019 | Acta Pharmaceutica Sinica B2019,9,2: | 20 |
| 3 | Exogenous abscisic acid significantly affects proteome in teaplant (Camellia sinensis) exposed to drought stress显示文摘Tea[Camellia sinensis(L.)O.Kuntze]is an important economic crop,and drought is the most important abiotic stress affecting yield and quality.Abscisic acid(ABA)is an important phytohormone responsible for activating drought resistance.Increased understanding of ABA effects on tea plant under drought stress is essential to develop drought-tolerant tea genotypes,along with crop management practices that can mitigate drought stress.The objective of the present investigation is evaluation of effects of exogenous ABA on the leaf proteome in tea plant exposed to drought stress.Leaf protein patterns of tea plants under simulated drought stress[(polyethylene glycol(PEG)-treated]and exogenous ABA treatment were analyzed in a time-course experiment using two-dimensional electrophoresis(2-DE),followed by matrix-assisted laser desorption/ionization time-of-flight(MALDI-TOF)mass spectrometry(MS).Among the 72 protein spots identified by MALDI-TOF MS,16 proteins were downregulated and two were upregulated by exogenous ABA.The upregulated proteins have roles in glycolysis and photosystem II stabilization.Twenty-one protein spots were responsive to drought stress and most participate in carbohydrate and nitrogen metabolism,control of reactive oxygen species(ROS),defense,signaling or nucleic acid metabolism.The combined treatments of exogenous ABA and drought showed upregulation of 10 protein spots at 12 h and upregulation of 11 proteins at 72 h after initiation of drought stress.The results support the importance of the role that ABA plays in the tea plant during drought stress,by improving protein transport,carbon metabolism and expression of resistance proteins. | Lin Zhou Hui Xu Sue Mischke Lyndel W Meinhardt Dapeng Zhang Xujun Zhu Xinghui Li Wanping Fang | 2014 | Horticulture Research2014,1,1: | 12 |

| 5 | Heat shock protein 90 promotes RNA helicase DDX5 accumulation and exacerbates hepatocellular carcinoma by inhibiting autophagy显示文摘Objective:Hepatocellular carcinoma(HCC),the main type of liver cancer,has a high morbidity and mortality,and a poor prognosis.RNA helicase DDX5,which acts as a transcriptional co-regulator,is overexpressed in most malignant tumors and promotes cancer cell growth.Heat shock protein 90(HSP90)is an important molecular chaperone in the conformational maturation and stabilization of numerous proteins involved in cell growth or survival.Methods:DDX5 m RNA and protein expression in surgically resected HCC tissues from 24 Asian patients were detected by quantitative real-time PCR and Western blot,respectively.The interaction of DDX5-HSP90 was determined by molecular docking,immunoprecipitation,and laser scanning confocal microscopy.The autophagy signal was detected by Western blot.The cell functions and signaling pathways of DDX5 were determined in 2 HCC cell lines.Two different murine HCC xenograft models were used to determine the function of DDX5 and the therapeutic effect of an HSP90 inhibitor.Results:HSP90 interacted directly with DDX5 and inhibited DDX5 protein degradation in the AMPK/ULK1-regulated autophagy pathway.The subsequent accumulation of DDX5 protein induced the malignant phenotype of HCC by activating theβ-catenin signaling pathway.The silencing of DDX5 or treatment with HSP90 inhibitor both blocked in vivo tumor growth in a murine HCC xenograft model.High levels of HSP90 and DDX5 protein were associated with poor prognoses.Conclusions:HSP90 interacted with DDX5 protein and subsequently protected DDX5 protein from AMPK/ULK1-regulated autophagic degradation.DDX5 and HSP90 are therefore potential therapeutic targets for HCC. | Ting Zhang Xinrui Yang Wanping Xu Jing Wang Dawei Wu Zhixian Hong Shengxian Yuan Zhen Zeng Xiaodong Jia Shanshan Lu Rifaat Safadi Sen Han Zhihong Yang Leonard M.Neckers Suthat Liangpunsakul Weiping Zhou Yinying Lu | 2021 | Cancer Biology & Medicine2021,18,3: | 7 |
| 6 | Developing single nucleotide polymorphism(SNP)markers from transcriptome sequences for identification of longan(Dimocarpus longan)germplasm显示文摘Longan(Dimocarpus longan Lour.)is an important tropical fruit tree crop.Accurate varietal identification is essential for germplasm management and breeding.Using longan transcriptome sequences from public databases,we developed single nucleotide polymorphism(SNP)markers;validated 60 SNPs in 50 longan germplasm accessions,including cultivated varieties and wild germplasm;and designated 25 SNP markers that unambiguously identified all tested longan varieties with high statistical rigor(P<0.0001).Multiple trees from the same clone were verified and off-type trees were identified.Diversity analysis revealed genetic relationships among analyzed accessions.Cultivated varieties differed significantly from wild populations(Fst=0.300;P<0.001),demonstrating untapped genetic diversity for germplasm conservation and utilization.Within cultivated varieties,apparent differences between varieties from China and those from Thailand and Hawaii indicated geographic patterns of genetic differentiation.These SNP markers provide a powerful tool to manage longan genetic resources and breeding,with accurate and efficient genotype identification. | Boyi Wang Hua-Wei Tan Wanping Fang Lyndel W Meinhardt Sue Mischke Tracie Matsumoto Dapeng Zhang | 2015 | Horticulture Research2015,2,1: | 6 |
| 7 | Metabolic and molecular analysis of nonuniform anthocyanin pigmentation in tomato fruit under high light显示文摘Pigment intensity and patterns are important factors that determine the nutritional and market values of tomato fruits.The acropetal manner of light-dependent anthocyanin accumulation with the highest levels at the stem end of the fruit makes Pro35S:BrTT8 tomato plants an ideal system for investigating the effects of light intensity on anthocyanin biosynthesis.Extensive transcript analyses indicate that anthocyanin pigmentation in Pro35S:BrTT8 plants under high light might be coordinately regulated by the exogenous protein BrTT8 and endogenous proteins SlAN2 and SlMYBL2.Furthermore,yeast two-hybrid assays showed that BrTT8 could interact efficiently with SlAN2,SlMYBL2,and SlAN11.Moreover,the physical interaction between BrTT8 and SlAN2 was validated by FRET.Simultaneous overexpression of SlAN2 and BrTT8 activated significant anthocyanin biosynthesis in infiltrated tobacco leaves.In addition,the ability of SlMYBL2 to suppress anthocyanin accumulation was also demonstrated in infiltrated tobacco leaves.Altogether,these results prove that tissue-specific assemblage of the heterogeneous MYB-bHLH-WD40 complex consisting of SlAN2,BrTT8 and SlAN11 triggers nonuniform anthocyanin accumulation in tomato fruit under high light.Additionally,it is proposed that a negative-feedback loop fulfilled by SlMYBL2 also participates in the regulation of anthocyanin production. | Yanjie Zhang Yan Li Wanping Li Zongli Hu Xiaohui Yu Yun Tu Min Zhang Jinyong Huang Guoping Chen | 2019 | Horticulture Research2019,6,1: | 4 |
| 8 | Identification of the varietal origin of processed loose-leaf tea based on analysis of a single leaf by SNP nanofluidic array显示文摘Tea is an important cash crop, representing a $40 billion-a-year global market. Differentiation of the tea market has resulted in increasing demand for tea products that are sustainably and responsibly produced. Tea authentication is important because of growing concerns about fraud involving premium tea products. Analytical technologies are needed for protection and value enhancement of high-quality brands. For loose-leaf teas, the challenge is that the authentication needs to be established on the basis of a single leaf, so that the products can be traced back to the original varieties. A new generation of molecular markers offers an ideal solution for authentication of processed agricultural products. Using a nanofluidic array to identify variant SNP sequences, we tested genetic identities using DNA extracted from single leaves of 14 processed commercial tea products. Based on the profiles of 60 SNP markers, the genetic identity of each tea sample was unambiguously identified by multilocus matching and ordination analysis. Results for repeated samples of multiple tea leaves from the same products(using three independent DNA extractions) showed 100% concordance, showing that the nanofluidic system is a reliable platform for generating tea DNA fingerprints with high accuracy. The method worked well on green, oolong, and black teas, and can handle a large number of samples in a short period of time. It is robust and cost-effective, thus showing high potential for practical application in the value chain of the tea industry. | Wanping Fang Lyndel W.Meinhardt Huawei Tan Lin Zhou Sue Mischke Xinghua Wang Dapeng Zhang | 2016 | The Crop Journal2016,4,4: | 4 |
| 9 | The tea plant CsLHT1 and CsLHT6 transporters take up amino acids, as a nitrogen source, from the soil of organic tea plantations显示文摘Organic tea is more popular than conventional tea that originates from fertilized plants.Amino acids inorganic soils constitute a substantial pool nitrogen(N)available for plants.However,the amino-acid contents in soils of tea plantations and how tea plants take up these amino acids remain largely unknown.In this study,we show that the amino-acid content in the soil of an organic tea plantation is significantly higher than that of a conventional tea plantation.Glutamate,alanine,valine,and leucine were the most abundant amino acids in the soil of this tea plantation.When 15 N-glutamate was fed to tea plants,it was efficiently absorbed and significantly increased the contents of other amino acids in the roots.We cloned seven CsLHT genes encoding amino-acid transporters and found that the expression of CsLHT1,CsLHT2,and CsLHT6 in the roots significantly increased upon glutamate feeding.Moreover,the expression of CsLHT1 or CsLHT6 in a yeast amino-acid uptake-defective mutant,22Δ10α,enabled growth on media with amino acids constituting the sole N source.Amino-acid uptake assays indicated that CsLHT1 and CsLHT6 are H^(+)-dependent high-and low-affinity amino-acid transporters,respectively.We further demonstrated that CsLHT1 and CsLHT6 are highly expressed in the roots and are localized to the plasma membrane.Moreover,overexpression of CsLHT1 and CsLHT6 in Arabidopsis significantly improved the uptake of exogenously supplied 15 N-glutamate and 15 N-glutamine.Taken together,our findings are consistent with the involvement of CsLHT1 and CsLHT6 in amino-acid uptake from the soil,which is particularly important for tea plants grown inorganic tea plantations. | Fang Li Chunxia Dong Tianyuan Yang Shilai Bao Wanping Fang William J.Lucas Zhaoliang Zhang | 2021 | Horticulture Research2021,8,1: | 3 |

| 11 | A Novel Anti-Human Syndecan-1 (CD138) Monoclonal Antibody 4B3: Characterization and Application显示文摘Syndecan-1 (CD138), a member of integral membrane heparin sulfate proteoglycans, is an essential matrix receptor for maintaining the normal morphological phenotypes. In this study, we generated a specific mouse anti-human syndecan-1 monoclonal antibody (mAb) 4B3 and identified it by competition assay with the available syndecan-1 mAb (BB4). Stained by 4B3, the expression of syndecan-1 was detected on tumor cell lines, such as 8226, U266, XG-1, XG-2, Daudi and Jurkat. The expression was also found on neuron stem cells. It was established that 4B3 mAb could inhibit XG-1 and XG-2 proliferation. The data not only determined that 4B3 mAb was a functional anti-human syndecan-1 mAb, but also indicated that syndecan-1 might be a valuable surface antigen and play an important role in regulation of tumor pathology and differentiation of neural stem cells. This novel antibody 4B3 may be value of study of tumor proliferation/survival mechanism and contributes to diagnosis and treatment of diverse diseases. | Wanping Sun Fengming Wang Fang Xie Guoqing Wang Jin Sun Gehua Yu Yuhua Qiu Xueguang Zhang | 2007 | Cellular & Molecular Immunology2007,4,3: | 1 |

| 14 | A programmable pAgo nuclease with RNA target-cleavage specificity from the mesophilic bacterium Verrucomicrobia显示文摘Argonaute(Ago)proteins are conserved programmable nucleases present in eukaryotes and prokaryotes and provide defense against mobile genetic elements.Almost all characterized pAgos prefer to cleave DNA targets.Here,we describe a novel pAgo from Verrucomicrobia bacterium(VbAgo)that can specifically cleave RNA targets rather than DNA targets at 37℃ and function as a multiple-turnover enzyme showing prominent catalytic capacity.VbAgo utilizes DNA guides(gDNAs)to cleave RNA targets at the canonical cleavage site.Meanwhile,the cleavage activity is remarkably strengthened at low concentrations of NaCl.In addition,VbAgo presents a weak tolerance for mismatches between gDNAs and RNA targets,and single-nucleotide mismatches at positions 11‒12 and dinucleotide mismatches at positions 3‒15 dramatically reduce target cleavage.Moreover,VbAgo can efficiently cleave highly structured RNA targets at 37℃.These properties of VbAgo broaden our understanding of Ago proteins and expand the pAgo-based RNA manipulation toolbox. | Qi Liu Wanping Chen Yue Zhang Fengyang Hu Xiaoman Jiang Fei Wang Yang Liu Lixin Ma | 2023 | Acta Biochimica et Biophysica Sinica2023,55,8: | 0 |
| 15 | Effects of Dietary Carbohydrate-lipid Ratio on Growth, Body Composition and Digestive Enzyme Activities of Juvenile Peanut Worm,Sipunculus nudus显示文摘[Objective] This study was conducted to investigate the effects of dietary carbohydrate-lipid( C / L) ratios on growth performance,body composition and digestive enzyme activities of juvenile peanut worm. [Methods]Juvenile peanut worm with average body weight of( 16. 77 ± 0. 40) mg were fed with five isonitrogenous and isoenergetic diets formulated to contain different carbohydrate / lipid( C / L) ratios( 0. 68,1. 02,1. 62,2. 61 or 4. 35) for 8 weeks. [Results] The dietary C / L ratios had no significant effects on survival of juvenile peanut worm( P > 0. 05). With the increasing of dietary C / L ratios,weight growth rate( WGR)and specific growth rate( SGR) increased when dietary C / L ratios were between 0. 68 and 2. 61,and then decreased significantly with dietary C / L ratio further increased. When the dietary C / L ratio was 2. 61( carbohydrate level was 20. 64%,lipid level was 7. 92%) both WGR and SGR produced the maximum value,they were 451. 78 ± 16. 85% and 3. 41 ± 0. 06 % / d,respectively. The dietary C / L ratios had significant effects on body moisture,body protein content and body lipid content( P < 0. 05),but no significant effects on body ash content of juvenile peanut worm( P > 0. 05). Different C / L ratios had significant effects on amylase activity and lipases activity of juvenile peanut worm( P < 0. 05),but no significant effects on protease activity( P > 0. 05). [Conclusion]The regression model analysis showed that the most suitable dietary C / L ratio which can make juvenile peanut worm acquire the best weight growth rate is 2. 42. | Zhang Qin Xu Mingzhu Tong Tong Tong Wanping Dong Lanfang Cheng Guangping Zou Jie Jiang Yan | 2014 | Animal Husbandry and Feed Science2014,6,5: | 0 |
| 16 | An ancient whole-genome duplication event and its contribution to flavor compounds in the tea plant (Camellia sinensis)显示文摘Tea,coffee,and cocoa are the three most popular nonalcoholic beverages in the world and have extremely high economic and cultural value.The genomes of four tea plant varieties have recently been sequenced,but there is some debate regarding the characterization of a whole-genome duplication(WGD)event in tea plants.Whether the WGD in the tea plant is shared with other plants in order Ericales and how it contributed to tea plant evolution remained unanswered.Here we re-analyzed the tea plant genome and provided evidence that tea experienced only WGD event after the core-eudicot whole-genome triplication(WGT)event.This WGD was shared by the Polemonioids-Primuloids-Core Ericales(PPC)sections,encompassing at least 17 families in the order Ericales.In addition,our study identified eight pairs of duplicated genes in the catechins biosynthesis pathway,four pairs of duplicated genes in the theanine biosynthesis pathway,and one pair of genes in the caffeine biosynthesis pathway,which were expanded and retained following this WGD.Nearly all these gene pairs were expressed in tea plants,implying the contribution of the WGD.This study shows that in addition to the role of the recent tandem gene duplication in the accumulation of tea flavor-related genes,the WGD may have been another main factor driving the evolution of tea flavor. | Ya Wang Fei Chen Yuanchun Ma Taikui Zhang Pengchuan Sun Meifang Lan Fang Li Wanping Fang | 2021 | Horticulture Research2021,8,1: | 0 |
| 17 | Recognition for avian influenza virus proteins based on support vector machine and linear discriminant analysis显示文摘Total 200 properties related to structural characteristics were employed to represent structures of 400 HA coded proteins of influenza virus as training samples. Some recognition models for HA proteins of avian influenza virus (AIV) were developed using support vector machine (SVM) and linear discriminant analysis (LDA). The results obtained from LDA are as follows: the identification accuracy (Ria) for training samples is 99.8% and Ria by leave one out cross validation is 99.5%. Both Ria of 99.8% for training samples and Ria of 99.3% by leave one out cross validation are obtained using SVM model, respectively. External 200 HA proteins of influenza virus were used to validate the external predictive power of the resulting model. The external Ria for them is 95.5% by LDA and 96.5% by SVM, respectively, which shows that HA proteins of AIVs are preferably recognized by SVM and LDA, and the performances by SVM are superior to those by LDA. | LIANG GuiZhao CHEN ZeCong YANG ShanBin MEI Hu ZHOU Yuan YANG Li ZHOU Peng YANG ShengXi SHU Mao LIAO ChunYang WU ShiRong LI GenRong HE Liu GAO JianKun Gan MengYu LI DeJing CHEN GuoPing WANG GuiXue LONG Sha JING JuHua ZHENG XiaoLin ZENG Hui ZHANG QiaoXia ZHANG MengJun YANG Qi TIAN FeiFei TONG JianBo WANG JiaoNa LIU YongHong LI Bo QIU LiangJia CAI ShaoXi ZHAO Na YANG Yan SU XiaLi SONG Jian CHEN MeiXia ZHANG XueJiao SUN JiaYing LI JingWei CHEN GuoHua CHEN Gang DENG Jie PENG ChuanYou ZHU WanPing XU LuoNan WU YuQuan LIAO LiMin LI Zhi LI Jun LU DaJun SU QinLiang HUANG ZhengHu ZHOU Ping LI ZhiLiang | 2008 | Science China Chemistry2008,51,2: | 0 |
| 18 | Preparation and Characterization of Nanostructured Lipid Carrier Loaded with UVA/UVB Filters显示文摘A new photoprotective system based on encapsulating UVA (butyl methoxydibenzoylmethane, BMBM) and UVB (octyl methoxycinnamate, OMC) filters into nanostructured lipid carriers (NLC) has been prepared to develop cosmetic formulations with effective UV protection. BMBM/OMC-loaded NLC was prepared by ultrasonication-homogenisation, and analysed by particle size, zeta potential (ZP), encapsulation efficiency (EE), scanning electron microscopy (SEM), fourier transform infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC). Moreover, the UV protection property and photostability were investigated and compared with BMBM/OMC-conventional emulsions. The particle size and ZP of BMBM/OMC-loaded NLC were 310.24 nm and -33.6 mV, EE of BMBM and OMC were 85.46% and 99.32%. SEM, FTIR and DSC analysis confirmed BMBM and OMC entrapped in the lipid matrix core and the structure was stable during storage. Compared with conventional emulsion, BMBM/OMC-loaded NLC displayed perfect photo protection property in whole UV range. The photostability studies showed that the NLC can improve the photostability of sunscreens. | Zhang Qianjie Zhao Xiaowei Song Lili Ou Wenhua Zhang WanPing Zhu Haiyang | 2018 | China Detergent & Cosmetics2018,3,4: | 0 |
| 19 | Targeted metabolomics reveals dynamic changes during the manufacturing process of Yuhua tea,a stir-fried green tea显示文摘The chemical composition of Yuhua tea is in a state of constant change during tea processing.However,the dynamic changes in this complex metabolic process remain unclear.Therefore,we detected the changes of compounds in the five stages of processing of Yuhua tea,and carried out metabolomic analysis based on UPLC–MS.In total,898 metabolites were detected in the five different stages.In the spreading and fixation processes,the differences in metabolites were the most significant,with 127 and 150 metabolites,respectively,undergoing significant changes.During the spreading period,the levels of amino acids and their derivatives,as well as flavonoids,increased sharply,and most continued to increase or stabilized after spreading.In addition,only 26 and 95 metabolites changed significantly during the rolling and drying processes,respectively.Orthogonal projections to latent structures-discriminant analysis showed that the metabolomics of tea changed significantly during the manufacturing process,especially amino acids and derivatives,flavonoids and lipids.This study provides a comprehensive overview of the metabolic changes during the processing of stir-fried green tea,which has potential significance for quality control and flavor improvement of tea. | Kexin Zhang Taiyu Ren Jieren Liao Shan Wang Zhongwei Zou Yuanchun Ma Fang Li Wanping Fang Xujun Zhu | 2021 | Beverage Plant Research2021,1,1: | 0 |
