6HIF-1α-induced expression of m6A reader YTHDF1 drives hypoxia-induced autophagy and malignancy of hepatocellular carcinoma by promoting ATG2A and ATG14 translation显示文摘N6-methyladenosine(m6A),and its reader protein YTHDF1,play a pivotal role in human tumorigenesis by affecting nearly everystage of RNA metabolism.Autophagy activation is one of the ways by which cancer cells survive hypoxia.However,the possibleinvolvement of m6A modification of mRNA in hypoxia-induced autophagy was unexplored in human hepatocellular carcinoma(HCO).In this study,specific variations in YTHDF1 expression were detected in YTHDF1-overexpressing,knockout,and-knockdownHCC cells,HCC organoids,and HCC patient-derived xenograft(PDX)murine models.YTHDF1 expression and hypoxia inducedautophagy were significantly correlated in vitro;signifhcant overexpression of YTHDF1 in HCC tissues was associated with poorprognosis,Multivariate cox regression analysis identihed YTHDF1 expression as an independent prognostic factor in patients withHCC.Multiple HC models conhrmed that YTHDF1 deficiency inhibited HCC autophagy,growth,and metastasis.Luciferase reporterassays and chromatin immunoprecipitation demonstrated that HlIF-1a regulated YTHDF1 transcription by directly binding to itspromoter region under hypoxia.The results of methylated RNA immunoprecipitation sequencing,proteomics,and polysomeprofling indicated that YTHDF1 contibuted to the translation of autophagy-related genes ATG2A and ATG14 by binding to m6A-modifhed ATG2A and ATG14 mRNA,thus facilitating autophagy and autophagy-related malignancy of HCC.Taken together,HlE-1d-induced YTHDF1 expression was associated with hypoxia-induced autophagy and autophagy-related HCC progression via promoting translation of autophagy-related genes ATG2A and ATG14 in a m6A-dependent manner.Our fndings suggest thatYTHDF1 is a potential prognostic biomarker and therapeutic target for patients with HCC.Qing Li Yong Ni Liren Zhang Runqiu Jiang Jing Xu Hong Yang Yuanchang Hu Jiannan Qiu Liyong Pu Jinhai Tang Xuehao Wang 2021Signal Transduction and Targeted Therapy2021,6,3:24
7Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China.Kaiwen Li Tianxin Lin Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang 2015Asian Journal of Urology2015,2,2:21
8The use of laser ranging to measure space debris显示文摘Space debris is a major problem for all the nations that are currently active in space.Adopting high-precision measuring techniques will help produce a reliable and accurate catalog for space debris and collision avoidance.Laser ranging is a kind of real-time measuring technology with high precision for space debris observation.The first space-debris laser-ranging experiment in China was performed at the Shanghai Observatory in July 2008 with a ranging precision of about 60-80 cm.The experimental results showed that the return signals from the targets with a range of 900 km were quite strong,with a power of 40W (2J at 20 Hz) using a 10ns pulse width laser at 532 nm wavelength.The performance of the preliminary laser ranging system and the observed results in 2008 and 2010 are also introduced.Zhong-Ping Zhang 1,2,Fu-Min Yang 1,Hai-Feng Zhang 1,Zhi-Bo Wu 1,2,Ju-Ping Chen 1,2,Pu Li 1 and Wen-Dong Meng 1 1 Shanghai Astronomical Observatory,Chinese Academy of Sciences,Shanghai 200030,China 2 Key Laboratory of Space Object and Debris Observation,Chinese Academy of Science,Nanjing 210008,China 2012Research in Astronomy and Astrophysics2012,12,2:20
9Isolation and Characterization of an Algicidal Bacterium Indigenous to Lake Taihu with a Red Pigment able to Lyse Microcystis aeruginosa显示文摘Objective To isolate and characterize indigenous algicidal bacteria and their algae-lysing compounds active against Microcystis aeruginosa, strains TH1, TH2, and FACHB 905. Methods The bacteria were identified using the Biolog automated microbial identification system and 16S rDNA sequence analysis. The algae-lysing compounds were isolated and purified by silica gel column chromatography and reverse-phase high performance liquid chromatography. Their structures were confirmed by Nuclear Magnetic Resonance (NMR) and Fourier Transform Infrared (FT-IR) spectroscopy. Algae-lysing activity was observed using microscopy. Results The algae-lysing bacterium LTH-2 isolated from Lake Taihu was identified as Serratia marcescens. Strain LTH-2 secreted a red pigment identified as prodigiosin (C 20 H 25 N 3 O), which showed strong lytic activity with algal strains M. aeruginosa TH1, TH2, and FACHB 905 in a concentration-dependent manner. The 50% inhibitory concentration (IC 50 ) of prodigiosin with the algal strains was 4.8 (±0.4)×10 -2 μg/mL, 8.9 (±1.1)×10-2 μg/mL, and 1.7 (±0.1)×10 -1 μg/mL in 24 h, respectively. Conclusion The bacterium LTH-2 and its pigment had strong Microcystis-lysing activity probably related to damage of cell membranes. The bacterium LTH-2 and its red pigment are potentially useful for regulating blooms of harmful M. aeruginosa.YANG Fei WEI Hai Yan LI Xiao Qin LI Yun Hui LI Xiao Bo YIN Li Hong PU Yue Pu 2013Biomedical and Environmental Sciences2013,26,2:19
10N6-Methyladenine DNA Methylation in Japonica and Indica Rice Genomes and Its Association with Gene Expression,Plant Development, and Stress Responses显示文摘N6-Methyladenine (6mA)DNA methylation has recently been implicated as a potential new epigenetic marker in eukaryotes,including the dioot modelArabidopsis thaliana.However,the conservation and divergence of 6mA distribution patterns and functions in plants remain elusive.Here we report high-quality 6mA methylomes at single-nucleotide resolution in rice based on substantially improved genome sequences of two rice cultivars,Nipponbare (Nip;Japonica)and 93-11 (Indica).Analysis of 6mA genomic distribution and its association with transcription suggest that 6mA distribution and function is rather conserved between rice and Arabidopsis.We found that 6mA levels are positively correlated with the expression of key stressrelated genes,which may be responsible for the difference in stress tolerance between Nip and 93-11. Moreover,we showed that mutations in DDM1 cause defects in plant growth and decreased 6mA level. Our results reveal that 6mA is a conserved DNA modification that is positively associated with gene expression and contributes to key agronomic traits in plants.Qian Zhang Zhe Liang Xuean Cui Changmian Ji Yun Li Pingxian Zhang Jingrong Liu Adeel Riaz Pu Yao Min Liu Yunpeng Wang Tiegang Lu Hao Yu Donglei Yang Hongkun Zheng Xiaofeng Gu 2018Molecular Plant2018,11,12:18
11Effectiveness of Different Waist Circumference Cut-off Values in Predicting Metabolic Syndrome Prevalence and Risk Factors in Adults in China显示文摘Objective To study the effectiveness of waist circumference cut-off values in predicting the prevalence of metabolic syndrome(MetS) and risk factors in adults in China. Methods A cross-sectional survey was condcuted in 14 provinces(autonomous region, municipality) in China. A total of 47 325 adults aged ≥20 years were selected by multistage stratified sampling, and questionnaire survey and physical and clinical examination were conducted among them. MetS was defined according to the International Diabetes Federation(IDF) criteria and modified IDF criteria.Results The age-standardized prevalence of MetS was 24.2%(22.1% in men and 25.8% in women) and 19.5%(22.1% in men and 18.0% in women) according to the IDF criteria and modified IDF criteria respectively. The age-standardized prevalence of pre-MetS was 8.1%(8.6% in men and 7.8% in women) according to the modified IDF criteria. The prevalence of MetS was higher in urban residents than rural residents and in northern China residents than in southern China residents. The prevalence of central obesity was about 30% in both men and women according to the ethnicity-specific cut-off values of waist circumference for central obesity(90 cm for men and 85 cm for women). Multivariate regression analysis revealed no significant difference in risk factors between the two MetS definitions. Conclusion Using both the modified IDF criteria and ethnicity-specific cut-off values of waist circumference can provide more useful information about the prevalence of MetS in China.ZHOU Hai Cheng LAI Ya Xin SHAN Zhong Yan JIA Wei Ping YANG Wen Ying LU Ju Ming WENG Jian Ping JI Li Nong LIU Jie TIAN Hao Ming JI Qiu He ZHU Da Long CHEN Li GUO Xiao Hui ZHAO Zhi Gang Li Qiang ZHOU Zhi Guang GE Jia Pu SHAN Guang Liang 2014Biomedical and Environmental Sciences2014,27,5:17

13Molecular fossil and paleovegetation records of paleosol S4 and adjacent loess layers in the Luochuan loess section, NW China显示文摘Using gas chromatography-mass spectrometry (GC-MS) technique, a series of biomarkers were identi- fied, including n-alkanes, n-alkane-2-ones, isoprenoid etc. from the loess-paleosol samples collected from the S4 and adjacent L5, L4 of the Luochuan loess section, Northwestern China. Based on these data, especially n-alkanes and high-resolution magnetic susceptibility and grain size data, the pa- leoenvironment and paleovegetation history during S4 was reconstructed. The CPI (Carbon Predomi- nance Index) and correlation between n-alkanes and magnetic susceptibility and grain size data dem- onstrated that the molecular fossils in paleosol and loess layers can reflect the vegetation condition during the loess-paleosol formation, if the allochthonous organic inputs could be excluded reasonably. The ACL (average chain length) index is correlated well with paleomagnetic susceptibility and grain size variations, displaying their good synchrony with warm and humid climate. However, it relatively lagged behind the paleomagnetic susceptibility and the grain size variations when the climate began to deteriorate. During the formation period of paleosol, the n-alkanes was dominated by C31 homologue, indicating that the primary organic input originated from herbs. Our study also demonstrated that the herbs were more flourish than wood plants in Loess Plateau, especially in the Luochuan area during the warm and humid phase, and there was no typical forest vegetation developed in the studied period.ZHANG HuCai YANG MingSheng ZHANG WenXiang LEI GuoLiang CHANG FengQin PU Yang FAN HongFang 2008Science China Earth Sciences2008,51,3:15
14bHLH121 Functions as a Direct Link that Facilitates the Activation of FIT by bHLH IVc Transcription Factors for Maintaining Fe Homeostasis in Arabidopsis显示文摘Iron(Fe)deficiency is prevalent in plants grown in neutral or alkaline soil.Plants have evolved sophisticated mechanisms that regulate Fe homeostasis,ensuring survival.In Arabidopsis,FER-LIKE IRON DEFICIENCY-INDUCED TRANSCRIPTION FACTOR(FIT)is a crucial regulator of Fe-deficiency response.FIT is activated indirectly by basic helix-loop-helix(bHLH)IVc transcription factors(TFs)under Fed eficiency;how ever,it remains unclear which protein(s)act as the linker to mediate the activation of FIT by bHLH IVc TFs.In this study,we characterize the functions of bHLH121 and demonstrate that it directly associates with the FIT promoter.We found that loss-of-function mutations of bHLH121 cause severe Fedeficiency symptoms,reduced Feaccum ulation,and disrupted expression of genes associated with Fehomeostasis.Genetic analysis showed that FIT is epistatic to bHLH121 and FIT overexpression partially rescues the bhlh121 mutant.Further investigations revealed that bHLH IVc TFs interact with and promote nuclear accumulation of bHLH121.We demonstrated that bHLH121 has DNA-binding activity and can bind the prom oters of the FIT and bHLHlb genes,but we did not find that it has either direct transcriptional activation or repression activity tow ard these genes.Meanw hile,we found that bHLH121 functions downstream of and is a direct target of bHLH IVc TFs,and its expression is induced by Fe deficiency in a bHLH IV c-dependent manner.Taken together,these results establish that bHLH121 functions together with bHLH IVc TFs to positively regulate the expression of FIT and thus plays a pivotal role in maintaining Fe homeostasis in Arabidopsis.Rihua Lei Yang Li Yuerong Cai Chenyang Li Mengna Pu Chengkai Lu Yujie Yang Gang Liang 2020Molecular Plant2020,13,4:14

16Numerical study on ULF waves in a dipole field excited by sudden impulse显示文摘A three-dimensional numerical model is employed to investigate ULF waves ex-cited by the sudden impulse (SI) of the solar wind dynamic pressure interacting with a dipole magnetosphere. We focus on the solar wind-magnetosphere energy coupling through ULF waves, and the influences of the SI spectrum on the cavity mode structure and the energy deposition due to field line resonances (FLRs) in the magnetosphere. The numerical results show that for a given SI lasting for 1 min with amplitude of 50 mV/m impinging on the subsolar magnetopause, the total ULF energy transported from the solar wind to the magnetosphere is about the magni-tude of 1014 J. The efficiency of the solar wind energy input is around 1%, which depends little on the location of the magnetopause in the model. It is also found that the energy of the cavity mode is confined in the region near the magnetopause, whereas, the energy of the toroidal mode may be distributed among a few specific L-shells. With a given size of the model magnetosphere and plasma density distri-bution, it is shown that the fundamental eigenfrequency of the cavity mode and the central locations of the FLRs do not vary noticeably with the power spectrum of the SI. It is worth noting that the spectrum of the SI affects the excitation of higher harmonics of the global cavity mode. The broader the bandwidth of the SI is, the higher harmonics of cavity mode could be excited. Meanwhile, the corresponding FLRs regions are broadened at the same time, which implies that the global cavity modes and toroidal modes can resonate on more magnetic L-shells when more harmonics of the global cavity modes appear.YANG Biao FU SuiYan ZONG QiuGang WANG YongFu ZHOU XuZhi PU ZuYin XIE Lun 2008Science China(Technological Sciences)2008,51,10:12

18Multi-spacecraft observations of ULF waves during the recovery phase of magnetic storm on October 30, 2003显示文摘Based on observations obtained by Cluster C1, GOES 10, 12, and Polar, the global ULF wave properties are studied during the recovery phase of a very intense magnetic storm-Halloween storm (October 31, 2003, 21:00-23:00 UT). The results indicate that the ULF waves’ properties observed by different satellites, such as amplitude, period, etc. show large variations. This can be interpreted as that Field Line Resonance (FLR) might take place in the region where Cluster C1 passed. The compressional wave of the cavity mode coupled with FLR’s shear Alfven wave and fed energy to the latter, forming a large-amplitude toroidal mode. From the point of period, Cluster C1 observed the shortest period, GOES 10, 12 observed the middle, while Polar observed the longest. The wave period of toroidal mode observed by Cluster C1 kept almost unchanging when Cluster C1 passed L range from 11.7 to 5.3. Using the Squared Wavelet Coherence analysis method, we estimated that the FLR region in the dayside magnetosphere could expand to at least 4 local time widths. The toroidal mode observed by Polar was a standing wave, while the pol-oidal mode was a propagating wave, the observation results could be well ex-plained by the waveguide mode theory. Since the solarwind speed Vx was -800 km/s and the dynamic pressure varied little, we speculated that the source of the ULF wave was the Kelvin-Helmholtz instability at the magnetopause triggered by high speed solarwind.YongFu Wang SuiYan Fu QiuGang Zong Biao Yang ZuYin Pu Lun Xie XuZhi Zhou 2008Science China(Technological Sciences)2008,51,10:11
19How to identify dislocations in molecular dynamics simulations?显示文摘Dislocations are of great importance in revealing the underlying mechanisms of deformed solid crystals.With the development of computational facilities and technologies,the observations of dislocations at atomic level through numerical simulations are permitted.Molecular dynamics(MD)simulation suggests itself as a powerful tool for understanding and visualizing the creation of dislocations as well as the evolution of crystal defects.However,the numerical results from the large-scale MD simulations are not very illuminating by themselves and there exist various techniques for analyzing dislocations and the deformed crystal structures.Thus,it is a big challenge for the beginners in this community to choose a proper method to start their investigations.In this review,we summarized and discussed up to twelve existing structure characterization methods in MD simulations of deformed crystal solids.A comprehensive comparison was made between the advantages and disadvantages of these typical techniques.We also examined some of the recent advances in the dynamics of dislocations related to the hydraulic fracturing.It was found that the dislocation emission has a significant effect on the propagation and bifurcation of the crack tip in the hydraulic fracturing.LI Duo WANG Feng Chao YANG Zhen Yu ZHAO Ya Pu 2014Science China(Physics,Mechanics & Astronomy)2014,57,12:11
20Endovascular treatment with or without intravenous alteplase for acute ischaemic stroke due to basilar artery occlusion显示文摘Background and purpose It remains controversial if endovascular treatment(EVT)can improve the outcome of patients with acute basilar artery occlusion(BAO).This study aims to compare the functional outcomes between EVT with and without intravenous thrombolysis(IVT)first in patients who had acute ischaemic stroke(AIS)due to BAO.Methods Patients who had AIS with BAO who underwent EVT within 24 hours of onset were enrolled in this multicentre cohort study,and the efficacy and safety were compared between IVT+EVT and direct EVT.The primary outcome was 90-day functional independence.All outcomes were assessed with adjusted OR(aOR)from the multivariable logistic regression.In addition,a meta-analysis was performed on all recently published pivotal studies on functional independence after EVT in patients with BAO.Results Of 310 enrolled patients with BAO,241(78%)were treated with direct EVT and 69(22%)with IVT+EVT.Direct EVT was associated with a worse functional outcome(aOR,0.46(95%CI 0.24 to 0.85),p=0.01).IVT+EVT was associated with a lower percentage of patients who needed≥3 passes of stent retriever(10.14%vs 20.75%).The meta-analysis regression revealed a potential positive correlation between bridging with IVT first and functional independence(r=0.14(95%CI 0.05 to 0.24),p<0.01).Conclusions This study showed that compared with direct EVT,EVT with IVT first was associated with better functional outcomes in patients with BAO treated within 24 hours of onset.The meta-analysis demonstrated similar favourable efficacy of IVT first followed by EVT in patients with BAO.Ximing Nie David Wang Yuehua Pu Yufei Wei Qixuan Lu Hongyi Yan Xin Liu Lina Zheng Jingyi Liu Xinxuan Yang Yarong Ding Dacheng Liu Wanying Duan Zhe Zhang Zhonghua Yang Miao Wen Weibin Gu Xinyi Hou Xinyi Leng Yuesong Pan Zhongrong Miao Liping Liu 2022Stroke & Vascular Neurology2022,7,3:10
