9Wnt/b-catenin signaling plays an ever-expanding role in stem cell self-renewal,tumorigenesis and cancer chemoresistance显示文摘Wnt signaling transduces evolutionarily conserved pathways which play important roles in initiating and regulating a diverse range of cellular activities,including cell proliferation,calcium homeostasis,and cell polarity.The role of Wnt signaling in controlling cell proliferation and stem cell self-renewal is primarily carried out through the canonical pathway,which is the best-characterized the multiple Wnt signaling branches.The past 10 years has seen a rapid expansion in our understanding of the complexity of this pathway,as many new components of Wnt signaling have been identified and linked to signaling regulation,stem cell functions,and adult tissue homeostasis.Additionally,a substantial body of evidence links Wnt signaling to tumorigenesis of cancer types and implicates it in the development of cancer drug resistance.Thus,a better understanding of the mechanisms by which dysregulation of Wnt signaling precedes the development and progression of human cancer may hasten the development of pathway inhibitors to augment current therapy.This review summarizes and synthesizes our current knowledge of the canonical Wnt pathway in development and disease.We begin with an overview of the components of the canonical Wnt signaling pathway and delve into the role this pathway has been shown to play in stemness,tumorigenesis,and cancer drug resistance.Ultimately,we hope to present an organized collection of evidence implicating Wnt signaling in tumorigenesis and chemoresistance to facilitate the pursuit of Wnt pathway modulators that may improve outcomes of cancers in which Wnt signaling contributes to aggressive disease and/or treatment resistance.Maryam K.Mohammed Connie Shao Jing Wang Qiang Wei Xin Wang Zachary Collier Shengli Tang Hao Liu Fugui Zhang Jiayi Huang Dan Guo Minpeng Lu Feng Liu Jianxiang Liu Chao Ma Lewis L.Shi Aravind Athiviraham Tong-Chuan He Michael J.Lee 2016Genes & Diseases2016,3,1:70
10Sodium butyrate attenuates high-fat diet-induced steatohepatitis in mice by improving gut microbiota and gastrointestinal barrier显示文摘AIM To investigate whether gut microbiota metabolite sodium butyrate(Na B)is an effective substance for attenuating non-alcoholic fatty liver disease(NAFLD)and the internal mechanisms.METHODS Male C57BL/6J mice were divided into three groups,normal control were fed standard chow and model group were fed a high-fat diet(HFD)for 16 wk,the intervention group were fed HFD for 16 wk and treated with Na B for 8 wk.Gut microbiota from each group were detected at baseline and at 16 wk,liver histology were evaluated and gastrointestinal barrier indicator such as zonula occluden-1(ZO-1)were detected by immunohistochemistry and realtime-PCR,further serum or liver endotoxin were determined by ELISA and inflammation-or metabolism-associated genes were quantified by real-time PCR.RESULTS Na B corrected the HFD-induced gut microbiota imbalance in mice,while it considerably elevated the abundances of the beneficial bacteria Christensenellaceae,Blautia and Lactobacil us.These bacteria can produce butyric acid in what seems like a virtuous circle.And butyrate restored HFD induced intestinal mucosa damage,increased the expression of ZO-1 in small intestine,further decreased the levels of gut endotoxin in serum and liver compared with HF group.Endotoxin-associated genes such as TLR4 and Myd88,pro-inflammation genes such as MCP-1,TNF-α,IL-1,IL-2,IL-6 and IFN-γin liver or epididymal fat were obviously downregulated after Na B intervention.Liver inflammation and fat accumulation were ameliorated,the levels of TG and cholesterol in liver were decreased after Na B intervention,NAS score was significantly decreased,metabolic indices such as FBG and HOMA-IR and liver function indicators ALT and AST were improved compared with HF group.CONCLUSION Na B may restore the dysbiosis of gut microbiota to attenuate steatohepatitis,which is suggested to be a potential gut microbiota modulator and therapeutic substance for NAFLD.Da Zhou Qin Pan Feng-Zhi Xin Rui-Nan Zhang Chong-Xin He Guang-Yu Chen Chang Liu Yuan-Wen Chen Jian-Gao Fan 2017World Journal of Gastroenterology2017,23,1:77
11Injectable hydrogels for cartilage and bone tissue engineering显示文摘Tissue engineering has become a promising strategy for repairing damaged cartilage and bone tissue. Among the scaffolds for tissue-engineering applications, injectable hydrogels have demonstrated great potential for use as three-dimensional cell culture scaffolds in cartilage and bone tissue engineering, owing to their high water content, similarity to the natural extracellular matrix(ECM), porous framework for cell transplantation and proliferation, minimal invasive properties, and ability to match irregular defects. In this review, we describe the selection of appropriate biomaterials and fabrication methods to prepare novel injectable hydrogels for cartilage and bone tissue engineering. In addition, the biology of cartilage and the bony ECM is also summarized. Finally, future perspectives for injectable hydrogels in cartilage and bone tissue engineering are discussed.Mei Liu Xin Zeng Chao Ma Huan Yi Zeeshan Ali Xianbo Mou Song Li Yan Deng Nongyue He 2017Bone Research2017,5,2:54

13Orbit determination and time synchronization for a GEO/IGSO satellite navigation constellation with regional tracking network显示文摘Aiming at regional services,the space segment of COMPASS (Phase I) satellite navigation system is a constellation of Geostationary Earth Orbit (GEO),Inclined Geostationary Earth Orbit (IGSO) and Medium Earth Orbit (MEO) satellites.Precise orbit determination (POD) for the satellites is limited by the geographic distribution of regional tracking stations.Independent time synchronization (TS) system is developed to supplement the regional tracking network,and satellite clock errors and orbit data may be obtained by simultaneously processing both tracking data and TS data.Consequently,inconsistency between tracking system and TS system caused by remaining instrumental errors not calibrated may decrease navigation accuracy.On the other hand,POD for the mixed constellation of GEO/IGSO/MEO with the regional tracking network leads to parameter estimations that are highly correlated.Notorious example of correlation is found between GEO's orbital elements and its clock errors.We estimate orbital elements and clock errors for a 3GEO+2IGSO constellation in this study using a multi-satellite precise orbit determination (MPOD) strategy,with which clock error elimination algorithm is applied to separate orbital and clock estimates to improve numerical efficiency.Satellite Laser Ranging (SLR) data are used to evaluate User Ranging Error (URE),which is the orbital error projected on a receiver's line-of-sight direction.Two-way radio-wave time transfer measurements are used to evaluate clock errors.Experimenting with data from the regional tracking network,we conclude that the fitting of code data is better than 1 m in terms of Root-Mean-Square (RMS),and fitting of carrier phase is better than 1 cm.For orbital evaluation,difference between computed receiver-satellite ranging based on estimated orbits and SLR measurements is better than 1 m (RMS).For clock estimates evaluation,2-hour linear-fitting shows that the satellite clock rates are about 1.E-10 s/s,while receiver clock rates are about 1×10 13-1×10 12 s/s.For the 72-hour POD experiment,the average differences between POD satellite clock rates estimates and clock measurements based on TS system are about 1×10 13 s/s,and for receiver clock rates,the differences are about 1×10 15 s/s.ZHOU ShanShi HU XiaoGong WU Bin LIU Li QU WeiJing GUO Rui HE Feng CAO YueLing Wu XiaoLi ZHU LingFeng SHI Xin TAN HongLi 2011Science China(Physics,Mechanics & Astronomy)2011,54,6:44
14A Kelch Motif-Containing Serine/Threonine Protein Phosphatase Determines the Large Grain QTL Trait in Rice显示文摘A thorough understanding of the genetic basis of rice grain traits is critical for the improvement of rice (Oryza sativa L.) varieties.In this study,we generated an F 2 population by crossing the large-grain japonica cultivar CW23 with Peiai 64 (PA64),an elite indica small-grain cultivar.Using QTL analysis,17 QTLs for five grain traits were detected on four different chromosomes.Eight of the QTLs were newly-identified in this study.In particular,qGL3-1,a newly-identified grain length QTL with the highest LOD value and largest phenotypic variation,was fine-mapped to the 17 kb region of chromosome 3.A serine/threonine protein phosphatase gene encoding a repeat domain containing two Kelch motifs was identified as the unique candidate gene corresponding to this QTL.A comparison of PA64 and CW23 sequences revealed a single nucleotide substitution (C→A) at position 1092 in exon 10,resulting in replacement of Asp (D) in PA64 with Glu (E) in CW23 for the 364th amino acid.This variation is located at the D position of the conserved sequence motif AVLDT of the Kelch repeat.Genetic analysis of a near-isogenic line (NIL) for qGL3-1 revealed that the allele qGL3-1 from CW23 has an additive or partly dominant effect,and is suitable for use in molecular marker-assisted selection.Zejun Hu Haohua He Shiyong Zhang Fan Sun Xiaoyun Xin Wenxiang Wang Xi Qian Jingshui Yang Xiaojin Luo 2012Journal of Integrative Plant Biology2012,54,12:41

16Enhanced secondary pollution offset reduction of primary emissions during COVID-19 lockdown in China显示文摘To control the spread of the 2019 novel coronavirus(COVID-19),China imposed nationwide restrictions on the movement of its population(lockdown)after the Chinese New Year of 2020,leading to large reductions in economic activities and associated emissions.Despite such large decreases in primary pollution,there were nonetheless several periods of heavy haze pollution in eastern China,raising questions about the well-established relationship between human activities and air quality.Here,using comprehensive measurements and modeling,we show that the haze during the COVID lockdown was driven by enhancements of secondary pollution.In particular,large decreases in NOx emissions from transportation increased ozone and nighttime NO_(3)radical formation,and these increases in atmospheric oxidizing capacity in turn facilitated the formation of secondary particulate matter.Our results,afforded by the tragic natural experiment of the COVID-19 pandemic,indicate that haze mitigation depends upon a coordinated and balanced strategy for controlling multiple pollutants.Xin Huang Aijun Ding Jian Gao Bo Zheng Derong Zhou Ximeng Qi Rong Tang Jiaping Wang Chuanhua Ren Wei Nie Xuguang Chi Zheng Xu Liangduo Chen Yuanyuan Li Fei Che Nini Pang Haikun Wang Dan Tong Wei Qin Wei Cheng Weijing Liu Qingyan Fu Baoxian Liu Fahe Chai Steven JDavis Qiang Zhang Kebin He 2021National Science Review2021,8,2:47

18Altitude dependency of trends of daily climate extremes in southwestern China, 1961-2008显示文摘A total of 12 indices of temperature extremes and 11 indices of precipitation ex-tremes at 111 stations in southwestern China at altitudes of 285-4700 m were examined for the period 1961-2008. Significant correlations of temperature extremes and elevation in-cluded the trends of diurnal temperature range, frost days, ice days, cold night frequency and cold day frequency. Regional trends of growing season length, warm night frequency, coldest night and warmest night displayed a statistically significant positive correlation with altitude. These characteristics indicated the obvious warming with altitude. For precipitation extreme indices, only the trends of consecutive dry days, consecutive wet days, wet day precipitation and the number of heavy precipitation days had significant correlations with increasing alti-tude owing to the complex influence of atmospheric circulation. It also indicated the increased precipitation mainly at higher altitude areas, whereas the increase of extreme precipitation events mainly at lowers altitude. In addition, the clearly local influences are also crucial on climate extremes. The analysis revealed an enhanced sensitivity of climate extremes to ele-vation in southwestern China in the context of recent warming.Li Zongxing He Yuanqing Theakstone, Wilfred H.

20Mineralogical and geochemical features of sulfide chimneys from the 49°39′E hydrothermal field on the Southwest Indian Ridge and their geological inferences显示文摘During January–May in 2007,the Chinese research cruise DY115-19 discovered an active hydrothermal field at 49°39′E/37°47′S on the ultraslow spreading Southwest Indian Ridge (SWIR).This was also the first active hydrothermal field found along an ultraslow-spreading ridge.We analyzed mineralogical,textural and geochemical compositions of the sulfide chimneys obtained from the 49°39′E field.Chimney samples show a concentric mineral zone around the fluid channel.The mineral assemblages of the interiors consist mainly of chalcopyrite,with pyrite and sphalerite as minor constitunets.In the intermediate portion,pyrite becomes the dominant mineral,with chalcopyrite and sphalerite as minor constitunets.For the outer wall,the majority of minerals are pyrite and sphalerite,with few chalcopyrite.Towards the outer margin of the chimney wall,the mineral grains become small and irregular in shape gradually,while minerals within interstices are abundant.These features are similar to those chimney edifices found on the East Pacific Rise and Mid-Atlantic Ridge.The average contents of Cu,Fe and Zn in our chimney samples were 2.83 wt%,45.6 wt% and 3.28 wt%,respectively.The average Au and Ag contents were up to 2.0 ppm and 70.2 ppm respectively,higher than the massive sulfides from most hydrothermal fields along mid-ocean ridge.The rare earth elements geochemistry of the sulfide chimneys show a pattern distinctive from the sulfides recovered from typical hydrothermal fields along sedimentstarved mid-ocean ridge,with the enrichment of light rare earth elements but the weak,mostly negative,Eu anomaly.This is attributed to the distinct mineralization environment or fluid compositions in this area.TAO ChunHui LI HuaiMing HUANG Wei HAN XiQiu WU GuangHai SU Xin ZHOU Ning LIN Jian HE YongHua ZHOU JianPing 2011Chinese Science Bulletin2011,56,26:34
