| 2 | Clinicopathological and prognostic analysis of 429 patients with intrahepatic cholangiocarcinoma显示文摘AIM:To understand the clinicopathological characteristics and treatment selections and improve survival and provide valuable information for patients with intrahepatic cholangiocarcinoma(ICC). METHODS:We retrospectively evaluated 5311 liver cancer patients who received resection between October 1999 and December 2003.Of these,429(8.1%)patients were diagnosed with ICC,and their clinicopathological, surgical,and survival characteristics were analyzed. RESULTS:Upper abdominal discomfort or pain(65.0%), no symptoms(12.1%),and hypodynamia(8.2%)were the major causes for medical attention.Laboratory tests showed 198(46.4%)patients were HBsAg positive, 90(21.3%)hadα-fetoprotein>20μg/L,50(11.9%) carcinoembryonic antigen>10μg/L,and 242(57.5%) carbohydrate antigen 19-9(CA19-9)>37 U/mL.Survival data was available for 329(76.7%)patients and their mean survival time was 12.4 mo.The overall survival of the patients with R0,R1 resection and punching exploration were 18.3,6.6 and 5.6 mo,respectively. Additionally,CA19-9>37 U/mL was associated with lymph node metastases,but inversely associated withcirrhosis.Multivariate analysis indicated that radical resection,lymph node metastases,macroscopic tumor thrombi and size,and CA19-9 were associated with prognosis. CONCLUSION:Surgical radical resection is still the most effective means to cure ICC.Certain laboratory tests(such as CA19-9)can effectively predict the survival of the patients with ICC. | Wei-Feng Shen Wei Zhong Feng Xu Tong Kan Li Geng Feng Xie Cheng-Jun Sui Jia-Mei Yang | 2009 | World Journal of Gastroenterology2009,15,47: | 39 |
| 3 | Baicalin induces ferroptosis in bladder cancer cells by downregulating FTH1显示文摘Ferroptosis is a non-apoptotic regulated cell death caused by iron accumulation and subsequent lipid peroxidation.Currently,the therapeutic role of ferroptosis on cancer is gaining increasing interest.Baicalin an active component in Scutellaria baicalensis Georgi with anticancer potential various cancer types;however,the effects of baicalein on bladder cancer and the underlying molecular mechanisms remain largely unknown.In the study,we investigated the effect of baicalin on bladder cancer cells5637 and KU-19-19.As a result,we show baicalin exerted its anticancer activity by inducing apoptosis and cell death in bladder cancer cells.Subsequently,we for the first time demonstrate baicalin-induced ferroptotic cell death in vitro and in vivo,accompanied by reactive oxygen species(ROS) accumulation and intracellular chelate iron enrichment.The ferroptosis inhibitor deferoxamine but not necrostatin-1,chloroquine(CQ),N-acetyl-L-cysteine,L-glutathione reduced,or carbobenzoxy-valyl-alanyl-aspartyl-[O-methyl]-fluoromethylketone(Z-VAD-FMK) rescued baicalin-induced cell death,indicating ferroptosis contributed to baicalin-induced cell death.Mechanistically,we show that ferritin heavy chain1(FTH1) was a key determinant for baicalin-induced ferroptosis.Overexpression of FTH1 abrogated the anticancer effects of baicalin in both 5637 and KU19-19 cells.Taken together,our data for the first time suggest that the natural product baicalin exerts its anticancer activity by inducing FTH1-dependent ferroptosis,which will hopefully provide a prospective compound for bladder cancer treatment. | Na Kong Xiaying Chen Jiao Feng Ting Duan Shuiping Liu Xueni Sun Peng Chen Ting Pan Lili Yan Ting Jin Yu Xiang Quan Gao Chengyong Wen Weirui Ma Wencheng Liu Mingming Zhang Zuyi Yang Wengang Wang Ruonan Zhang Bi Chen Tian Xie Xinbing Sui Wei Tao | 2021 | Acta Pharmaceutica Sinica B2021,11,12: | 23 |

| 7 | Enhancement of acellular cartilage matrix scaffold by Wharton’s jelly mesenchymal stem cell-derived exosomes to promote osteochondral regeneration显示文摘Articular cartilage defect repair is a problem that has long plagued clinicians.Although mesenchymal stem cells(MSCs)have the potential to regenerate articular cartilage,they also have many limitations.Recent studies have found that MSC-derived exosomes(MSC-Exos)play an important role in tissue regeneration.The purpose of this study was to verify whether MSC-Exos can enhance the reparative effect of the acellular cartilage extracellular matrix(ACECM)scaffold and to explore the underlying mechanism.The results of in vitro experiments show that human umbilical cord Wharton’s jelly MSC-Exos(hWJMSC-Exos)can promote the migration and proliferation of bone marrow-derived MSCs(BMSCs)and the proliferation of chondrocytes.We also found that hWJMSC-Exos can promote the polarization of macrophages toward the M2 phenotype.The results of a rabbit knee osteochondral defect repair model confirmed that hWJMSC-Exos can enhance the effect of the ACECM scaffold and promote osteochondral regeneration.We demonstrated that hWJMSC-Exos can regulate the microenvironment of the articular cavity using a rat knee joint osteochondral defect model.This effect was mainly manifested in promoting the polarization of macrophages toward the M2 phenotype and inhibiting the inflammatory response,which may be a promoting factor for osteochondral regeneration.In addition,microRNA(miRNA)sequencing confirmed that hWJMSC-Exos contain many miRNAs that can promote the regeneration of hyaline cartilage.We further clarified the role of hWJMSC-Exos in osteochondral regeneration through target gene prediction and pathway enrichment analysis.In summary,this study confirms that hWJMSC-Exos can enhance the effect of the ACECM scaffold and promote osteochondral regeneration. | Shuangpeng Jiang Guangzhao Tian Zhen Yang Xiang Gao Fuxin Wang Juntan Li Zhuang Tian Bo Huang Fu Wei Xinyu Sang Liuqi Shao Jian Zhou Zhenyong Wang Shuyun Liu Xiang Sui Quanyi Guo Weimin Guo Xu Li | 2021 | Bioactive Materials2021,6,9: | 11 |
| 8 | Reactive oxygen species-based nanomaterials for the treatment of myocardial ischemia reperfusion injuries显示文摘Interventional coronary reperfusion strategies are widely adopted to treat acute myocardial infarction,but morbidity and mortality of acute myocardial infarction are still high.Reperfusion injuries are inevitable due to the generation of reactive oxygen species(ROS)and apoptosis of cardiac muscle cells.However,many antioxidant and anti-inflammatory drugs are largely limited by pharmacokinetics and route of administration,such as short half-life,low stability,low bioavailability,and side effects for treatment myocardial ischemia reperfusion injury.Therefore,it is necessary to develop effective drugs and technologies to address this issue.Fortunately,nanotherapies have demonstrated great opportunities for treating myocardial ischemia reperfusion injury.Compared with traditional drugs,nanodrugs can effectively increase the therapeutic effect and reduces side effects by improving pharmacokinetic and pharmacodynamic properties due to nanodrugs’size,shape,and material characteristics.In this review,the biology of ROS and molecular mechanisms of myocardial ischemia reperfusion injury are discussed.Furthermore,we summarized the applications of ROS-based nanoparticles,highlighting the latest achievements of nanotechnology researches for the treatment of myocardial ischemia reperfusion injury. | Tianjiao Zhao Wei Wu Lihua Sui Qiong Huang Yayun Nan Jianhua Liu Kelong Ai | 2022 | Bioactive Materials2022,7,1: | 11 |
| 9 | Molecular Cloning and Expression of Squalene Epoxidase from a Medicinal Plant, Bupleurum chinense显示文摘Objective In plant, squalene epoxidase(SE) catalyzes the first oxygenation step in the biosynthetic pathway of triterpenoid and phytosterol, representing one of the rate-limiting enzymes in this pathway. Bupleurum chinense is an important medicinal herb with its major active constituents such as triterpenoid saponins and saikosaponins. In order to obtain the series of enzymatic genes involved in saikosaponin biosynthesis, a c DNA of SE, designated Bc SE1, was cloned from B. chinense. Methods The Bc SE1 gene was cloned by homology-based PCR and 5'/3' RACE methods from the adventitious roots of B. chinense. The physical and chemical parameters of Bc SE1 protein were predicted by protparam. In order to discover hints in amino acid sequences on the dominant functions in the biosynthesis of saponin or phytosterol, sequences of SE from other plants were downloaded from NCBI for sequences alignment and phylogenetic analysis. Bc SE1 was cloned into a yeast mutant KLN1(MATa, erg1::URA3, leu2, ura3, and trp1) to verify the enzyme activity of Bc SE1. Additionally, the tissue-specific expression and methyl jasmonate(Me JA) inducibility of Bc SE1 were investigated using quantitative real-time PCR. Results The predicted protein of Bc SE1 is highly similar to SEs from other plants sharing amino acid sequence identities of up to 88%. The Bc SE1 can functionally complement with yeast SE gene(ERG1) when expressed in the KLN1 mutant(MATa, erg1::URA3, leu2, ura3, and trp1). Using as controls with β-amyrin synthase(β-AS) which is presumed to catalyze the first committed step in saikosaponin biosynthesis and a cycloartenol synthase(CAS) relating to the phytosterol biosynthesis, the transcript of Bc SE1 was significantly elevated by Me JA in adventitious roots of B. chinense and the transcript of Bc SE1 was most abundant in the fruits and flowers of plants, followed by that in the leaves and roots, and least in stems. Conclusion It is the first time to illustrate the molecular information of SE in B. chinense and to clone the full-length SE gene in plants of genus Bupleurum L. | Ke Gao Jie-sen Xu Jing Sun Yan-hong Xu Jian-he Wei Chun Sui | 2016 | Chinese Herbal Medicines2016,8,1: | 10 |

| 11 | Progress of regional oceanography study associated with western boundary current in the South China Sea显示文摘Recent progress of physical oceanography in the South China Sea (SCS) associated with the western boundary current (WBC) and eddies is reviewed in this paper. It includes Argo observations of the WBC, eddy detection in the WBC based on satellite images, cross-continental shelf exchange in the WBC, eddy-current interaction, interannual variability of the WBC, air-sea interaction, the SCS throughflow (SCSTF), among others. The WBC in the SCS is strong, and its structure, variability and dynamic processes on seasonal and interannual time scales are yet to be fully understood. In this paper, we summarize progresses on the variability of the WBC, eddy-current interaction, air-sea interaction, and the SCSTF achieved in the past few years. Firstly, using the drifting buoy observations, we point out that the WBC becomes stronger and narrower after it reaches the central Vietnam coast. The possible mechanisms influencing the ocean circulation in the northern SCS are discussed, and the dynamic mechanisms that induce the countercurrent in the region of northern branch of WBC in winter are also studied quantitatively using momentum balance. The geostropic component of the WBC was diagnosed using the ship observation along 18°N, and we found that the WBC changed significantly on interannual time scale. Secondly, using the ship observations, two anti-cyclonic eddies in the winter of 2003/2004 in the northern SCS, and three anti-cyclonic eddies in the summer of 2007 along 18°N were studied. The results show that the two anti-cyclonic eddies can propagate southwestward along the continental shelf at the speed of first Rossby wave (~0.1 ms-1 ) in winter, and the interaction between the three anti-cyclonic eddies in summer and the WBC in the SCS is preliminarily revealed. Eddies on the continental shelf of northern SCS propagated southeastward with a maximum speed of 0.09 ms-1 , and those to the east of Vietnam coast had the largest kinetic energy, both of which imply strong interaction between eddy activity and WBC in the SCS. Thirdly, strong intraseasonal variability (ISV) of sea surface temperature (SST) near the WBC regions was found, and the ISV signal of SST in winter weakens the ISV signal of latent heat flux by 20%. Fourthly, the long-term change of SCSTF volume transport and its connection with the ocean circulation in the Pacific were discussed. | WANG DongXiao LIU QinYan XIE Qiang HE ZhiGang ZHUANG Wei SHU YeQiang XIAO XianJun HONG Bo WU XiangYu SUI DanDan | 2013 | Chinese Science Bulletin2013,58,11: | 10 |
| 12 | Mortality outcomes of low-dose computed tomography screening for lung cancer in urban China:a decision analysis and implications for practice显示文摘Background: Mortality outcomes in trials of low-dose computed tomography(CT) screening for lung cancer are inconsistent. This study aimed to evaluate whether CT screening in urban areas of China could reduce lung cancer mortality and to investigate the factors that associate with the screening effect.Methods: A decision tree model with three scenarios(low-dose CT screening, chest X-ray screening, and no screening) was developed to compare screening results in a simulated Chinese urban cohort(100,000 smokers aged45-80 years). Data of participant characteristics were obtained from national registries and epidemiological surveys for estimating lung cancer prevalence. The selection of other tree variables such as sensitivities and specificities of low-dose CT and chest X-ray screening were based on literature research. Differences in lung cancer mortality(primary outcome), false diagnoses, and deaths due to false diagnosis were calculated. Sensitivity analyses were performed to identify the factors that associate with the screening results and to ascertain worst and optimal screening effects considering possible ranges of the variables.Results: Among the 100,000 subjects, there were 448,541, and 591 lung cancer deaths in the low-dose CT, chest X-ray, and no screening scenarios, respectively(17.2% reduction in low-dose CT screening over chest X-ray screening and 24.2% over no screening). The costs of the two screening scenarios were 9387 and 2497 false diagnoses and 7and 2 deaths due to false diagnosis among the 100,000 persons, respectively. The factors that most influenced death reduction with low-dose CT screening over no screening were lung cancer prevalence in the screened cohort, lowdose CT sensitivity, and proportion of early-stage cancers among low-dose CT detected lung cancers. Considering all possibilities, reduction in deaths(relative numbers) with low-dose CT screening in the worst and optimal cases were16(5.4%) and 288(40.2%) over no screening, respectively.Conclusions: In terms of mortality outcomes, our findings favor conducting low-dose CT screening in urban China.However, approaches to reducing false diagnoses and optimizing important screening conditions such as enrollment criteria for screening are highly needed. | Zixing Wang Wei Han Weiwei Zhang Fang Xue Yuyan Wang Yaoda Hu Lei Wang Chunwu Zhou Yao Huang Shijun Zhao Wei Song Xin Sui Ruihong Shi Jingmei Jiang | 2017 | Chinese Journal of Cancer2017,36,8: | 9 |
| 13 | Psychological impact of the COVID-19 pandemic on healthcare workers:a cross-sectional study in China显示文摘Background Healthcare workers fighting against the coronavirus disease 2019(COVID-19)pandemic are under tremendous pressure,which puts them at an increased risk of developing psychological problems.Aims This study aimed to investigate the prevalence of psychological problems in different healthcare workers(ie,physicians,medical residents,nurses,technicians and public health professionals)during the COVID-19 pandemic in China and explore factors that are associated with the onset of psychological problems in this population during this public health crisis.Methods A cross-sectional,web-based survey was conducted in February 2020 among healthcare workers during the COVID-19 pandemic.Psychological problems were assessed using the Generalized Anxiety Disorder Scale,Patient Health Questionnaire and Insomnia Severity Index.Logistic regression analyses were used to explore the factors that were associated with psychological problems.Results The prevalence of symptoms of anxiety,depression,insomnia and the overall psychological problems in healthcare workers during the COVID-19 pandemic in China was 46.04%,44.37%,28.75%and 56.59%,respectively.The prevalence of the overall psychological problems in physicians,medical residents,nurses,technicians and public health professionals was 60.35%,50.82%,62.02%,57.54%and 62.40%,respectively.Compared with healthcare workers who did not participate in front-line work,front-line healthcare workers had a higher risk of anxiety,insomnia and overall psychological problems.In addition,attention to negative or neutral information about the pandemic,receiving negative feedback from families and friends who joined front-line work,and unwillingness to join front-line work if given a free choice were three major factors for these psychological problems.Conclusions Psychological problems are pervasive among healthcare workers during the COVID-19 pandemic.Receiving negative information and participating in front-line work appear to be.important risk factors for psychological problems.The psychological health of different healthcare workers should be protected during the COVID-19 pandemic with timely interventions and proper information feedback. | Jianyu Que Le Shi Jiahui Deng Jiajia Liu Li Zhang Suying Wu Yimiao Gong Weizhen Huang Kai Yuan Wei Yan Yankun Sun Maosheng Ran Yanping Bao Lin Lu | 2020 | General Psychiatry2020,33,3: | 8 |
| 14 | Inositol Pyrophosphate lnsP8 Acts as an Intracellular Phosphate Signal in Arabidopsis显示文摘The maintenance of cellular phosphate(Pi)homeostasis is of great importance in living organisms.The SPX domain-containing protein 1(SPX1)proteins from both Arabidopsis and rice have been proposed to act as sensors of Pi status.The molecular signal indicating the cellular Pi status and regulating Pi homeostasis in plants,however,remains to be identified,as Pi itself does not bind to the SPX domain.Here,we report the identification of the inositol pyrophosphate lnsP8 as a signaling molecule that regulates Pi homeostasis in Arabidopsis.Polyacrylamide gel electrophoresis profiling of InsPs revealed that lnsP8 level positively correlates with cellular Pi concentration.We demonstrated that the homologs of diphosphoinositol pentaki-sphosphate kinase(PPIP5K),VIH1 and VIH2,function redundantly to synthesize lnsP8,and that the vih1 vih2 double mutant overaccumulates Pi.SPX1 directly interacts with PHR1,the central regulator of Pi starvation responses,to inhibit its function under Pi-replete conditions.However,this interaction is compromised in the vih1 vih2 double mutant,resulting in the constitutive induction of Pi starvation-induced genes,indicating that plant cells cannot sense cellular Pi status without lnsP8.Furthermore,we showed that lnsP8 could directly bind to the SPX domain of SPX1 and is essential for the interaction between SPX1 and PHR1.Collectively,our study suggests that lnsP8 is the intracellular Pi signaling molecule serving as the ligand of SPX1 for controlling Pi homeostasis in plants. | Jinsong Dong Guojie Ma Liqian Sui Mengwei Wei Viswanathan Satheesh Ruyue Zhang Shenghong Ge Jinkai Li Tong-En Zhang Christopher Wittwer Henning JJessen Huiming Zhang Guo-Yong An Dai-Yin Chao Dong Liu Mingguang Lei | 2019 | Molecular Plant2019,12,11: | 8 |
| 15 | Application of CRISPR/Cas9 in plant biology显示文摘The CRISPR/Cas(clustered regularly interspaced short palindromic repeats/CRISPRassociated proteins) system was first identified in bacteria and archaea and can degrade exogenous substrates. It was developed as a gene editing technology in 2013. Over the subsequent years, it has received extensive attention owing to its easy manipulation, high efficiency, and wide application in gene mutation and transcriptional regulation in mammals and plants. The process of CRISPR/Cas is optimized constantly and its application has also expanded dramatically. Therefore, CRISPR/Cas is considered a revolutionary technology in plant biology. Here, we introduce the mechanism of the type II CRISPR/Cas called CRISPR/Cas9, update its recent advances in various applications in plants, and discuss its future prospects to provide an argument for its use in the study of medicinal plants. | Xuan Liu Surui Wu Jiao Xu Chun Sui Jianhe Wei | 2017 | Acta Pharmaceutica Sinica B2017,7,3: | 8 |
| 16 | Preparation of multi-walled carbon nanotube-reinforced TiNi matrix composites from elemental powders by spark plasma sintering显示文摘Carbon nanotube (CNT)-reinforced TiNi matrix composites were synthesized by spark plasma sintering (SPS) employing elemental powders.The phase structure,morphology and transformation behaviors were studied.It was found that thermoelastic martensitic transformation be-haviors could be observed from the samples sintered above 800 ℃ even with a short sintering time (5min),and the transformation tempera-tures gradually increased with increasing sintering temperature because of more Ti-rich TiNi phase formation.Although decreasing the sin-tering temperature and time to 700 ℃ and 5min could not protect defective MWCNTs from reacting with Ti,still-perfect MWCNTs re-mained in the specimens sintered at 900 ℃.This method is expected to supply a basis for preparing CNT-reinforced TiNi composites. | CAI Wei,FENG Xue,and SUI Jiehe National Key Laboratory Precision Hot Processing of Metals,School of Materials Science and Engineering,Harbin Institute of Technology,Harbin 150001,China | 2012 | Rare Metals2012,31,1: | 7 |

| 18 | Effects of flooding stress on the photosynthetic apparatus of leaves of two Physocarpus cultivars显示文摘We applied under pot-culture conditions and the double-casing pot method to study the characteristics of photosynthetic gas exchange and chlorophyll fluorescence in the leaves of Physocarpus amurensis Maxim(PA) and Physocarpus opulifolius under flooding stress.Our results indicate a significantly higher flooding tolerance of P.opulifolius compared to P.amurensis.Especially in P.amurensis, the limitation of non-stomatal factors played a major role in the advanced stages of flooding stress,observed as a rapid increase of the intercellular CO_2 concentration(C_i) and a decrease of the stomatal limitation value(L_s).The maximal PSII photochemical efficiencies(F_v/F_m) and actual photochemical efficiency(?_(PSII)) in the leaves of P.opulifolius were significantly higher, and the extent of decrease during the flooding process was smaller than in P.amurensis.In addition, the non-chemical quenching(NPQ) in the leaves of P.opulifolius significantly increased from the 10 th day under flooding stress,while the variation of NPQ in the leaves of P.amurensis was much smaller.This indicates that the leaves of P.opulifolius had not only higher PSII photochemical activity, but also improved tolerance to flooding stress, which may be caused by its ability to dissipate excess excitation energy by starting NPQ.At the 16 th day under flooding stress, the PIABSsignificantly decreased with greater extent of decrease than F_v/F_m in the leaves of both Physocarpus,but the decreasing extent of PIABSin P.opulifolius was significantly smaller than in P.amurensis.In the 16 th day under flooding stress, the fluorescence at J and I point(V_J and V_I) in P.amurensis were significantly higher, and the extent of increase in V_J was greater than V_I.However, the variations of V_Jand V_I in the leaves of P.opulifolius were smaller, suggesting that the damage sites of flooding stress to PSII in the leaves of P.amurensis were mainly located in the electron transport process from Q_A at the PSII receptor side to Q_B.Flooding stress reduced the proportion(φ Eo) of luminous energy absorbed by the PSII reaction center for the electron transport following Q_A^-, while the maximum quantum yield(φ Do) of non-photochemical quenching increased.However, the TR_o/RC and ETo/RC in the leaves of P.amurensis decreased accompanied by a dramatic increase of energy(DI_o/RC) from the dissipation in the reaction center.This further indicated that the function of the PSII reaction center in the leaves of P.amurensis was significantly lower than in P.opulifolius. | Huihui Zhang Peng Feng Wei Yang Xin Sui Xin Li Wei Li Rongtao Zhang Siyu Gu Nan Xu | 2018 | Journal of Forestry Research2018,29,4: | 6 |
| 19 | Integrated transcriptome and proteome analysis provides insight into chilling-induced dormancy breaking in Chimonanthus praecox显示文摘Chilling has a critical role in the growth and development of perennial plants.The chilling requirement(CR)for dormancy breaking largely depends on the species.However,global warming is expected to negatively affect chilling accumulation and dormancy release in a wide range of perennial plants.Here,we used Chimonanthus praecox as a model to investigate the CR for dormancy breaking under natural and artificial conditions.We determined the minimum CR(570 chill units,CU)needed for chilling-induced dormancy breaking and analyzed the transcriptomes and proteomes of flowering and non-flowering flower buds(FBs,anther and ovary differentiation completed)with different CRs.The concentrations of ABA and GA3 in the FBs were also determined using HPLC.The results indicate that chilling induced an upregulation of ABA levels and significant downregulation of SHORT VEGETATIVE PHASE(SVP)and FLOWERING LOCUS T(FT)homologs at the transcript level in FBs when the accumulated CR reached 570 CU(IB570)compared to FBs in November(FB.Nov,CK)and nF16(non-flowering FBs after treatment at 16℃for−300 CU),which suggested that dormancy breaking of FBs could be regulated by the ABA-mediated SVP-FT module.Overexpression in Arabidopsis was used to confirm the function of candidate genes,and early flowering was induced in 35S::CpFT1 transgenic lines.Our data provide insight into the minimum CR(570 CU)needed for chilling-induced dormancy breaking and its underlying regulatory mechanism in C.praecox,which provides a new tool for the artificial regulation of flowering time and a rich gene resource for controlling chilling-induced blooming. | Zhineng Li Ning Liu Wei Zhang Chunyu Wu Yingjie Jiang Jing Ma Mingyang Li Shunzhao Sui | 2020 | Horticulture Research2020,7,1: | 6 |
| 20 | Cloning and Expression Analysis on 3-Hydroxy-3-methylglutaryl-coenzyme A Reductase from Aquilaria sinensis显示文摘Objective To clone the full-length cDNA of 3-hydroxy-3-methylglutaryl-coenzyme A reductase(HMGR)from Aquilaria sinensis(AsHMGR1)and to analyze its expression profile in different tissues and in response to different treatments.HMGR is the first rate-limiting enzyme for sesquiterpene synthesis in the mevalonate pathway.Methods RT-PCR and RACE were used to clone the full-length cDNA of HMGR from A.sinensis based on the conserved HMGR gene fragments.The bioinformatic analysis was performed on its nucleic acid and protein sequence.The expression profile of AsHMGR1 in different tissues and in response to different treatments was analyzed by quantitative RT-PCR.Results The full-length AsHMGR1 cDNA was 2026 bp,containing a 1719 bp open reading frame which encoded a protein of 572 amino acids.Amino acid sequence homology alignment and phylogenetic analysis demonstrated that AsHMGR1 belonged to the HMGR gene family.The detection of tissue expression patterns showed that AsHMGR1 was mainly expressed in the stem,followed by roots and branches.AsHMGR1 could be stimulated by methyl jasmonate and H2O2to varying degrees in a time-dependent manner.Conclusion These data will provide a foundation for further investigation on AsHMGR1 functions and regulatory mechanisms in sesquiterpene synthesis in A.sinensis. | XU Yan-hong YANG Xin WEI Jian-he ZHANG Xing-li ZHANG Zheng GAO Zhi-hui SUI Chun | 2013 | Chinese Herbal Medicines2013,5,3: | 6 |
