2Dual-specificity histone demethylase KIAA1718 (KDM7A) regulates neural differentiation through FGF4显示文摘histone H3 离氨酸的 Dimethylations 9 和离氨酸 27 是与抄写压抑联系的重要 epigenetic 标记。这里,我们作为为这二个镇压标记特定的新奇 histone demethylase 识别了 KIAA1718 (KDM7A ) 。用老鼠胚胎的干细胞,我们证明那 KIAA1718 表情在神经区别的早阶段增加了。基因击倒堵住的神经区别和效果被野类型的人的基因,并且不由催化地不活跃的异种救。另外, KIAA1718 的 overexpression 加速了神经区别。我们提供 KDM7A 的支持 neural 区别效果通过 FGF4 的直接 transcriptional 激活被调停的证据,一个信号分子在神经区别含有。因此,我们的学习识别了通过 FGF4 调整神经区别的双特性的 histone demethylase。Chengyang Huang Yang Xiang Yanru Wang Xia Li Longyong Xu Ziqi Zhu Ting Zhang Qingqing Zhu Kejing Zhang Naihe Jing Charlie Degui Chen 2010Cell Research2010,20,2:15
3P wave velocity structure of upper and middle crust beneath the Three Gorges reservoir dam and adjacent regions显示文摘The three-dimensional P wave velocity structures of upper and middle crust beneath the Three Gorges reservoir dam and adjacent regions were reconstructed by means of the seismic tomography, using the absolute P-arrivals from the events observed by the Three Gorges seismic network. Our preliminary study of the deep structure shows: (1) the lithology of the Huangling anticline, integral and highly so-lidified, exhibits a uniformity. Down to a depth of 20 km, the Huangling anticline still shows high- velocity anomalies. Note that the characteristics of the velocity images with the different depths are not the same; (2) the depth of the sedimentary rocks beneath the entire Zigui basin is not constant, which is less than 6 km; (3) the top boundary of the crystalline basement varies from 0 to 7 km, whereas the bottom one between 14 and 16 km; (4) the partially molten substances of the upper mantle are located in the Badong-Zigui and its adjacent regions as well as nearby Peishi area. The development and evo-lution of the current tectonics are associated with the cooling and solidifying process of the molten substances within the upper mantle; (5) the different velocity structures of the deep crust in both east and west side of the Jiuwanxi fault are to be investigated in order to understand the origin of gravita-tional gradient zone in the Three Gorge areas; and (6) the velocities within the upper crust would be affected by reservoir water permeability.LI Qiang ZHAO Xu CAI JinAn LIU RuiFeng LONG GuiHua AN YanRu 2009Science China Earth Sciences2009,52,4:11
4Identification of seed-specific promoter nap300 and its comparison with 7S promoter显示文摘By fusing seed-specific promoter nap300 with β-glucuronidase gene, it was found that this about 300bp DNA fragment was sufficient to direct seed-specific gene expression. The substitution mutation in both distB and proxB elements had a little effect on the expression efficiency and almost no effect on the organ-specific expression pattern. In the experiment designed to compare nap300 with 7S promoter, the result showed that tissue specificity for nap300 was higher than that for 7S, and its expression level was lower than 7S's. There was no big difference in their expression pattern, and the maximal activity stage for the two promoters was identical, which indicated they could be used simultaneously for expressing different foreign genes in seeds.ZHANG Jingyu, LI Li and SONG Yanru(Key Laboratory of Photosynthesis and Enviromental Molecular Physiology, Institute of Botany, Chinese Academy of Sciences, Beijing 100093, China) 2002Progress in Natural Science:Materials International2002,12,10:9
5Arabidopsis VQ10 interacts with WRKY8 to modulate basal defense against Botrytis cinerea显示文摘Recent studies in Arabidopsis have revealed that some VQ motif-containing proteins physically interact with WRKY transcription factors;however,their specific biological functions are still poorly understood.In this study,we confirmed the interaction between VQ10and WRKY8,and show that VQ10 and WRKY8 formed a complex in the plant cell nucleus.Yeast two-hybrid analysis showed that the middle region of WRKY8 and the VQ motif of VQ10 are critical for their interaction,and that this interaction promotes the DNA-binding activity of WRKY8.Further investigation revealed that the VQ10protein was exclusively localized in the nucleus,and VQ10was predominantly expressed in siliques.VQ10 expression was strongly responsive to the necrotrophic fungal pathogen,Botrytis cinerea and defense-related hormones.Phenotypic analysis showed that disruption of VQ10 increased mutant plants susceptibility to the fungal pathogen B.cinerea,whereas constitutive-expression of VQ10 enhanced resistance to B.cinerea.Consistent with these findings,expression of the defenserelated PLANT DEFENSIN1.2(PDF1.2)gene was decreased in vq10 mutant plants,after B.cinerea infection,but increased in VQ10-overexpressing transgenic plants.Taken together,our findings provide evidence that VQ10 physically interacts with WRKY8 and positively regulates plant basal resistance against the necrotrophic fungal pathogen B.cinerea.Junqiu Chen Houping Wang Yang Li Jinjing Pan Yanru Hu Diqiu Yu 2018Journal of Integrative Plant Biology2018,60,10:8
6Bimetallic Ru-Ni/TiO2 catalysts for hydrogenation of N-ethylcarbazole:Role of TiO2 crystal structure显示文摘Hydrogenation of N-ethylcarbazole(NEC),the hydrogen lean form of a liquid organic hydrogen carrier,on TiO2 supported Ru-Ni bimetallic catalysts is investigated.Crystal structure of TiO2 plays a critical role on the hydrogenation activity and selectivity towards fully hydrogenated product.Ru/anatase catalyst exhibits higher selectivity but lower reactivity compared to Ru/rutile catalyst.Ni addition significantly promotes the performance of Ru/anatase catalyst while causes severe performance deterioration of Ru/rutile catalyst.Commercial P25,a mixture of anatase and rutile phases in approximate ratio A/R1/4,is found to be the best TiO2 support for NEC hydrogenation.Ru/P25 catalyst outperforms both Ru/rutile and Ru/anatase and its activity can be further slightly improved by Ni addition.The unexpected synergism between the two different TiO2 phases for Ru based NEC hydrogenation catalysts is related to metal-support interaction and Ru-Ni interaction.Hongen Yu Xue Yang Yong Wu Yanru Guo Shuan Li Wei Lin Xingguo Li Jie Zheng 2020Journal of Energy Chemistry2020,29,1:7
7PHF8 is a histone H3K9me2 demethylase regulating rRNA synthesis显示文摘histone H3 离氨酸 9 的 Dimethylation (H3K9me2 ) 是与抄写压抑联系的一个重要 epigenetic 标记。这里,我们识别了 PHF8, JmjC-domain-containing 蛋白质,为这个镇压标记特定的 histone demethylase。Recombinant 全身的野类型蛋白质能把 methylation 从 H3K9me2 移开,但是到丙氨酸 H247A 的保存 histidine 的变化废除 demethylase 活动。Overexpressed 外长的 PHF8 是 colocalized, B23 染色。内长的 PHF8 也是有 B23 和 fibrillarin 的 colocalized,二生长得很好的核蛋白质,建议那 PHF8 在核是局部性的并且可以调整 rRNA 抄写。确实, PHF8 跳了到 rDNA 基因的倡导者区域。减少的 PHF8 击倒 rRNA 的表示,和基因的 overexpression 导致了 rRNA 的 upregulation 抄本。附随地, H3K9me2 水平在 PHF8 击倒的房间在 rDNA 基因的倡导者区域被提高并且当野类型然而并非催化地不活跃的 H247A 变异的 PHF8 是 overexpressed 时,显著地减少了。因此,我们的学习为调整 rRNA 抄写的 H3K9me2 识别了 histone demethylase。Ziqi Zhu Yanru Wang Xia Li Yiqin Wang Longyong Xu Xiang Wang Tianliang Sun Xiaobin Dong Lulu Chen Hailei Mao Yi Yu Jingsong Li Pin Adele Chen Charlie Degui Chen 2010Cell Research2010,20,7:7
8Characterization of 500 Chinese patients with cervical esophageal cancer by clinicopathological and treatment outcomes显示文摘Objective: There are no comprehensive studies on survival outcomes and optimal treatment protocols for cervical esophageal cancer(CEC), due to its rare clinical prevalence. Our objective was to determine the relationship between pathological characteristics, treatment protocols, and survival outcomes in Chinese CEC patients.Methods: A total of 500 Chinese CEC patients were selected from our 500,000 esophageal and gastric cardia carcinoma database(1973–2018). There were two main groups: patients treated with surgery, and patients receiving non-surgical treatments(radiotherapy, radiochemotherapy, and chemotherapy). The Chi-square test and Kaplan–Meier method were used to compare the continuous variables and survival.Results: Among the 500 CEC patients, 278(55.6%) were male, and the median age was 60.9 ± 9.4 years. A total of 496 patients(99.2%) were diagnosed with squamous cell carcinoma. In 171(34.2%) patients who received surgery, 22(12.9%) had undergone laryngectomy. In 322(64.4%) patients who received non-surgical treatments, 245(76.1%) received radiotherapy. Stratified survival analysis showed that only T stage was related with survival outcomes for CEC patients in the surgical group, and the outcomes between laryngectomy and non-laryngectomy patients were similar. It was noteworthy that the 5-year survival rate was similar in CEC patients among the different groups treated with surgery, radiotherapy, chemotherapy, or radiochemotherapy(P = 0.244). Conclusions: The CEC patients had similar survival outcomes after curative esophagectomy and radiotherapy, including those with or without total laryngectomy. These findings suggest that radiotherapy could be the initial choice for treatment of Chinese CEC patients.Peinan Chen Xueke Zhao Fuyou Zhou Xin Song Shoujia Hu Yan Jin Xianzeng Wang Xuena Han ZongminFan Ran Wang Bei Li Wenli Han Panpan Wang Jilin Li Lixin Wan Liguo Zhang Qide Bao Fubao Chang Yanru Qin Zhiwei Chang Jianwei Ku Haijun Yang Ling Yuan Jingli Ren Xuemin Li Lidong Wang 2020Cancer Biology & Medicine2020,17,1:6
9Pertuzumab in combination with trastuzumab and chemotherapy for Chinese patients with HER2-positive metastatic gastric or gastroesophageal junction cancer:a subpopulation analysis of the JACOB trial显示文摘Background:The JACOB trial(NCT01774786)was a double-blinded,placebo-controlled,randomized,multicenter,international,phase III trial evaluating the efficacy and safety of adding pertuzumab to trastuzumab and chemo-therapy in first-line treatment of human epidermal growth factor receptor 2(HER2)-positive metastatic gastric cancer/gastroesophageal junction cancer(GEJC).The aim of this analysis was to investigate efficacy and safety outcomes in the Chinese subpopulation from the JACOB trial.Methods:This post hoc subpopulation analysis included all patients recruited in China's Mainland(n=163;20.9%)between June 2013 and January 2016.The patients were randomly assigned in a 1:1 ratio to receive pertuzumab plus trastuzumab and chemotherapy(pertuzumab group;n=82)or placebo plus trastuzumab and chemotherapy(con-trol group;n=81).Intravenous pertuzumab(840 mg)and trastuzumab(8 mg/kg loading and 6 mg/kg maintenance doses)were given every 3 weeks until disease progression or unacceptable toxicity.Chemotherapy was given as per standard regimens/doses of capecitabine or 5-fluorouracil plus cisplatin.The primary endpoint was overall survival(OS);secondary efficacy endpoints included progression-free survival(PFS),and overall objective response rate(ORR).Results:The median OS was 18.7 months in the pertuzumab group and 16.1 months in the control group(hazard ratio[HR]0.75;95%confidence interval[CI]0.49 to 1.14).The median PFS was 10.5 and 8.6 months in the pertuzumab and control groups,respectively(HR 0.85;95%CI 0.60 to 1.21),and the median ORRs were 68.9%and 55.7%,respectively.The treatment effect in this Chinese subpopulation showed consistency with that in the global ITT population with numerically lower HR for OS and PFS compared with the control group.The safety profiles of the pertuzumab and control groups in this Chinese subpopulation analysis were generally comparable.The most common grade 3-5adverse events were neutropenia,anemia,and leukopenia.However,due to the nature of being a post hoc subgroup analysis,the results presented here are descriptive only and need to be interpreted with caution.Conclusions:OS and PFS were numerically improved by adding pertuzumab to trastuzumab and chemotherapy as first-line treatment in Chinese HER2-positive gastric cancer/GEJC patients,and this regimen demonstrated an acceptable safety profile.Tianshu Liu Yanru Qin Jin Li Ruihua Xu Jianming Xu Shujun Yang Shukui Qin Yuxian Bai Changping Wu Yixiang Mao Haiyan Wu Yilin Ge Lin Shen 2019Cancer Communications2019,39,1:6
10Pulping performance of transgenic poplar with depressed Caffeoyl-CoA O-methyltransferase显示文摘This paper evaluated pulping performance of 3-year-old field-grown transgenic poplar (Populus tremula × Populus alba). The transgenic poplar with anti-sense CCoAOMT had an about 13% decreased lignin content, in which a slight increment was found in S/G ratio. Chemical analysis showed that the transgenic poplar had significantly less benezene-ethanol extractive than that of control wood, but no significant differences were found in contents of ash, cold water extractive, hot water extractive, 1% NaOH extractive, holocellulose, pentosans and cellulose. Fiber assay demonstrated that down-regulation of CCoAOMT expression improved the fiber quality in transgenic poplar. Kraft pulping showed that lower lignin in transgenic poplar led to remarkable improved pulp quality and increased pulp yield.WEI JianHua WANG YanZhen WANG HongZhi LI RuiFen LIN Nan MA RongCai QU LeQing SONG YanRu 2008Chinese Science Bulletin2008,53,22:5
11Large numbersLarge numbers of new bacterial taxa found by Yunnan Institute of Microbiology显示文摘Extreme environments, primeval forest, sea sediments and plants in China yielded members of a new suborder, Jiangellineae, a new family Sinobacteraceae, and 23 new genera of actinomycetes and other bacteria. Three suggestions were made for further discoveries of new actinomycetes. First, natural habitats such as old growth forests, and extreme environments, should be given sampling priority; second, culturing procedures need to be constantly improved to mimic natural habitats; third, less than 98.5% similarity of 16S rRNA sequence to that of a known species could be used as an indicator of a new species.JIANG Yi CAO YanRu ZHAO LiXing TANG ShuKun WANG Yun LI WenJun XU Ping LOU Kai MAO PeiHong XU LiHua 2011Chinese Science Bulletin2011,56,8:5
12The landscape of gene-CDS-haplotype diversity in rice:Properties,population organization,footprints of domestication and breeding,and implications for genetic improvement显示文摘Polymorphisms within gene coding regions represent the most important part of the overall genetic diversity of rice.We characterized the gene-coding sequence-haplotype(gcHap)diversity of 45963 rice genes in 3010 rice accessions.With an average of 226±390 gcHaps per gene in rice populations,rice genes could be classified into three main categories:12865 conserved genes,10254 subspecific differentiating genes,and 22844 remaining genes.We found that 39218 rice genes carry>255179 major gcHaps of potential functional importance.Most(87.5%)of the detected gcHaps were specific to subspecies or populations.The inferred proto-ancestors of local landrace populations reconstructed from conserved predominant(ancient)gcHaps correlated strongly with wild rice accessions from the same geographic regions,supporting a multiorigin(domestication)model of Oryza sativa.Past breeding efforts generally increased the gcHap diversity of modern varieties and'caused significant frequency shifts in predominant gcHaps of 14266 genes due to independent selection in the two subspecies.Low frequencies of“favorable”gcHaps at most known genes related to rice yield in modern varieties suggest huge potential for rice improvement by mining and pyramiding of favorable gcHaps.The gcHap data were demonstrated to have greater power than SNPs for the detection of causal genes that affect complex traits.The rice gcHap diversity dataset generated in this study would facilitate rice basic research and improvement in the future.Fan Zhang Chunchao Wang Min Li Yanru Cui Yingyao Shi Zhichao Wu Zhiqiang Hu Wensheng Wang Jianlong Xu Zhikang Li 2021Molecular Plant2021,14,5:5
13Characteristics of the coseismic geomagnetic disturbances recorded during the 2008 M_w 7.9 Wenchuan Earthquake and two unexplained problems显示文摘Twenty-seven FHDZ-M15 combined geomagnetic observation systems(each of which is equipped with a fluxgate magnetometer and a proton magnetometer)had been installed in the China geomagnetic network before the 2008 Wenchuan earthquake,during which coseismic disturbances were recorded by 26 fluxgate magnetometer observatories.The geomagnetic disturbances have similar spatial and temporal patterns to seismic waves,except for various delays.Six proton magnetometer observatories recorded coseismic disturbances with very small amplitudes.In addition,fluxgate magnetometers registered largeamplitude disturbances that are likely to have included responses to seismic waves.However,two problems remain unresolved.First,why do these geomagnetic disturbances always arrive later than P waves?Second,why do the geomagnetic disturbances have spatial and temporal directivity similar to the main rupture direction of the earthquake?Solving these two problems may be crucial to find the mechanism responsible for generating these geomagnetic anomalies.YaLi Wang Tao Xie YanRu An Chong Yue JiuYang Wang Chen Yu Li Yao Jun Lu 2019Earth and Planetary Physics2019,3,5:4
14Construction of plant seed-specific expression vectors pSCB and pSCAB and the obtainment of transgenic Brassica napus H165 expressing poly-3-hydroxybutyrate synthetic genes显示文摘The seed-specific promoter and transit peptide were amplified and fused to the three genes phbA, phbB and phbC encoding PHB synthetic enzymes, respectively. Seed-specific expression vectors pSCB containing phbC and phbB, and pSCAB containing phbC, phbB and phbA, were constructed by introducing the genes with promoter and peptide into the binary vector pBI101. Transgenic Brassica napus H165 were obtained by Agrobacterium-mediated transformation with these vectors. They were confirmed by PCR, Southern and RT-PCR analyses.Liang Ye Cong Li Yanru Song 2000Chinese Science Bulletin2000,45,13:4

16The effect of serum luteinizing hormone on trigger day with a GnRH antagonist protocol in IVF/ICSI treatment显示文摘Objective:To investigate the effect of serum luteinizing hormone(LH)on trigger day with a Gonadotrophinreleasing hormone(GnRH)antagonist protocol in patients receiving in vitro fertilization/intracytoplasmic sperm injection(IVF/ICSI)treatment for pregnancy outcomes.Methods:We retrospectively reviewed the medical documents of patients receiving IVF/ICSI with fresh embryo transfers from the Reproductive Medicine Center of Peking University People's Hospital between January 2016 and December 2018.730 patients were included and divided into three groups by their serum LH level determined on trigger day.All patients were categorized into Group A,Group B,and Group C based on LH concentrations<1.0 IU/L,1.0–5.0 IU/L,and from 5.0 to 10.0 IU/L on trigger day during the cycle,respectively.Comparisons were made between the three groups.Results:There was a significant difference in implantation rates between Group A and Group C(24.8%versus 40.1%,respectively,P<0.05).The clinical pregnancy rates(39.3%versus 54.3%,respectively,P=0.078)and live birth rate(LBR)(32.1%versus 46.5%,respectively,P=0.116),though the differences were not significant.Multivariate logistic regression analysis showed that the OR of Group C for clinical pregnancy(OR=1.849,P=0.040)and for LBR(OR=1.915,P=0.034)were significant using Group A as the base level.Conclusions:Our study has demonstrated that patients with higher serum LH levels(5.0–10.0 IU/L)on trigger day in the GnRH antagonist protocol may confer better clinical outcomes than those with lower LH levels(<1.0 IU/L).Yanru Hou Li Tian Huixin Liu Jiajia Ai Yanbin Wang Huan Shen 2021Gynecology and Obstetrics Clinical Medicine2021,1,4:2
17Screening and flocculating properties of bioflocculant-producing microorganisms显示文摘Screening of bioflocculant-producing microorganisms was carried out. A strain that secreted excellent bioflocculant was isolated from municipal sewage using the spread plate technique, identified as Klebsiella sp. by the analytical profile index (API) identification system, and named A9. Several important factors that had an effect on A9’s bioflocculant-producing and flocculating activity were studied. A total of 4 g/L Kaolin suspension was used to measure the flocculating activity of the bioflocculant from A9. It was found that maltose and urea were A9’s best carbon and nitrogen sources, respectively, and the flocculating activity of the floccu- lating agent from A9 was markedly increased by the addition of trivalent cations such as Fe3+ and Al3+; furthermore, the bioflocculant produced by A9 was most effective when the pH value was 6.0.Yanling Sheng Qiang Zhang Yanru Sheng Chengbin Li and Huajun Wang 2006Journal of University of Science and Technology Beijing2006,13,4:2
18Genome editing and animal models显示文摘Transgenic technology allows a gene of interest to be introduced into the genome of a laboratory animal,and provides an extremely powerful tool to dissect the molecular mechanisms of disease.Transgenic mouse models made by microinjection of DNA into zygotic pronuclei in particular have been widely used by the genetics community for 30 years.However,it remains a rather crude approach:injected sequences randomly insert in multiple copies as concatamers,they can be mutagenic,and they have variable or silenced expression depending on the site of integration,a phenomenon called position effects.As a result,multiple lines are required in order to confirm appropriate transgene expression.This can be partially overcome by flanking transgenes with insulator sequences to protect the transgene from the influence of the surrounding regulatory elements.Large(\300 kb)BACbased transgenic vectors have also been shown to be more resistant to position effects.However,animals carrying extra copies of fairly large regions of the genome could have unpredictable phenotypes.The most effective method used to control for position effects is to target transgene insertion to specific genomic loci,the so-called targeted transgenesis;for instance,the fast,site-specific transgenic technology Targatt TM.The purpose of this review is to provide an overview on the current existing methods for making targeted transgenic mouse models.Ruby Yanru Chen-Tsai Ruhong Jiang Luping Zhuang Junfeng Wu Lingsong Li Jiarui Wu 2014Chinese Science Bulletin2014,59,1:2
19Cloning and sequencing of phbA gene of poly-β-hydroxybuty rate synthesis and its expression analysis显示文摘The gene of the first key enzyme of poly-β-hydroxybutyrate synthesis, 3-ketothiolase, has been amplified and cloned from chromosomal DNA of Alcaligenes eutrophus H16 by PCR. DNA sequencing results show that phbA cloned in pBluescriptSK^+ has an identical sequence with that reported previously except for one base pair. The plant constitutive expression vector has been constructed and tobacco has been transformed in order to examine the phbA gene function and the efficiency of ctp gene product. SDS-polyacrylamide gel electrophoresis result shows that the ctp gene product could direct foreign protein into plastid efficiently and phbA gene could be translated into corresponding protein with correct size. The enzyme activity analysis of 3-ketothiolase shows that the enzyme could catalyze acetyl-CoA to form acetoacetylCoA.Liang Ye Cong Li Yanru Song 1999Chinese Science Bulletin1999,44,15:2
