1Wnt/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
22018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up.Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu 2018Science Bulletin2018,63,23:54
3Effects of rh BNP after PCI on non-invasive hemodynamic in acute myocardial infarction patients with left heart failure显示文摘Objective: To investigate the effects of exogenous recombinant human brain natriuretic peptide(rh BNP) after primary percutaneous coronary intervention(PCI) on non-invasive hemodynamic in acute myocardial infarction patients with left ventricular failure. Methods: A number of 96 acute myocardial infarction patients accompanied with heart failure after PCI hospitalized in the People's Hospital of Sanya during February 2012 to October 2015 were selected. They were randomly divided into the therapy group(n = 50) and control group(n = 46). On the basis of routine treatment, patients in the therapy group were treated with intravenous rh BNP(1.5 μg/kg was intravenous injection with uniform speed of 3 min, followed by continuous infusion 0.007 5 μg/kg·min for 72 h), while the control group received conventional treatment. Bio Z-2011 non-invasive hemodynamic real-time monitoring system was used to monitor the hemodynamic parameters changes and the leves of plasma pro-BNP, serum creatinine, serum potassium, serum sodium and urine volume of each group before and after treating for 30 min, 1 h, 3 h, 6 h, 12 h, 24 h, 48 h, 72 h. Results: Patients in the therapy group showed no effect on heart rate, while after 30 min of intravenous injection of rh BNP, CO, CI, SV, and SI increased significantly and LVET and TFC reduced at the same time, which had certain effect on blood pressure(SBP/DBP). Compared with the control group, the therapy group showed a faster and more effective improvement on haemodynamics. Conclusions: Acute myocardial infarction patients complicated with left heart failure after primary PCI can significantly improve hemodynamics by treating with rh BNP.Xi-Min He Lin Chen Jiang-Bin Luo Xu-Xia Feng Yun-Bo Zhang Qi-Jing Chen Xiao-Li Ji Tian-Song Wang 2016Asian Pacific Journal of Tropical Medicine2016,9,8:52
4An Investigation of Oxidative DNA Damage in Pharmacy Technicians Exposed to Antineoplastic Drugs in Two Chinese Hospitals Using The Urinary 8-OHdG Assay显示文摘Objective To investigate oxidative DNA damage in pharmacy technicians preparing antineoplastic drugs at the PIVAS (Pharmacy Intravenous Admixture Service) in two Chinese hospitals.Methods Urinary 8-OHdG served as a biomarker.5-Fluorouracil (5-FU) concentrations in air,masks and gloves were determined.The spill exposure of each PIVAS technician to antineoplastic drugs was investigated.Eighty subjects were divided into exposed group I,II,and control group I,II.Results 5-FU concentration ratios for gloves and masks in exposed group I were significantly higher than those in exposed group II (P<0.05 or P<0.01).The average urinary 8-OHdG concentrations in exposed group I,control group I,exposed group II,and control group II were 14.69±0.93,10.68±1.07,10.57±0.55,and 11.96±0.73 ng/mg Cr,respectively.Urinary 8-OHdG concentration in exposed group I was significantly higher than that in control group I or that in exposed group II (P<0.01).There was a significant correlation between urinary 8-OHdG concentrations and spill frequencies per technician (P<0.01).Conclusion There was detectable oxidative DNA damage in PIVAS technicians exposed to antineoplastic drugs.This oxidative DNA damage may be associated with their spill exposure experience and contamination of their personal protective equipment.HUANG Yu Wen JIAN Le ZHANG Mei Bian ZHOU Quan YAN Xiao Feng HUA Xu Dong ZHOU Ying HE Ji Liang 2012Biomedical and Environmental Sciences2012,25,1:30
5Ginsenoside Rgl protects against ischemic/reperfusioninduced neuronal injury through miR-144/Nrf2/ARE pathway显示文摘Ginsenoside Rg1 (Rg1),a saponin extracted from Panax ginseng,has been well documented to be effective against ischemic/ reperfusion (I/R)neuronal injury.However,the underlying mechanisms remain obscure.In the present study,we investigated the roles of Nrf2 and miR-144 in the protective effects of Rgl against I/R-induced neuronal injury.In OGD/R-treated PC12 cells,Rgl (0.01-1 μmol/L)dose-dependently attenuated the cell injury accompanied by prolonging nuclear accumulation of Nrf2,enhancing the transcriptional activity of Nrf2,as well as promoting the expression of ARE-target genes.The activation of the Nrf2/ARE pathway by Rgl was independent of disassociation with Keapl,but resulted from post-translational regulations.Knockdown of Nrf2 abolished all the protective changes of Rgl in OG-D/R-treated PC12 cells.Furthermore,Rgl treatment significantly decreased the expression of miR-144,which downregulated Nrf2 production by targeting its 3'-untranlated region after OGD/R.Knockdown of Nrf2 had no effect on the expression of miR-144,suggesting that miR-144 was an upstream regulator of Nrf2.We revealed that there was a direct binding between Nrf2 and miR-144 in PC12 cells.Application of anti-miR-144 occluded the activation of the Nrf2/ ARE pathway by Rgl in OGD/R-treated PC12 cells.In tMCAO rats,administration of Rgl (20 mg/kg).significantly alleviated ischemic injury,and activated Nff2/ARE pathway.The protective effects of Rgl were abolished by injecting of AAV-HIF-miR-144-shRNA into the predicted ischemic penumbra.In conclusion,our results demonstrate that Rgl alleviates oxidative,stress after I/R through inhibiting miR-144 activity and subsequently promoting the Nrf2/ARE pathway at the post-translational-level.Shi-feng Chu Zhao Zhang Xin Zhou Wen-bin He Chen Chen Piao Luo Dan-dan Liu Qi-di Ai Hai-fan Gong Zhen-zhen Wang Hong-shuo Sun Zhong-ping Feng Nai-hong Chen 2019Acta Pharmacologica Sinica2019,40,1:30
6Time constraints for the closing of the Paleo-Asian Ocean in the Northern Alxa Region: Evidence from Wuliji granites显示文摘The Wuliji pluton in the Northern Alxa Region, Inner Mongolia, is the principal part of Shalazhashan Mountain. It belongs to the Zongnaishan-Shalazhashan Arc Zone, northwestern North China Plate, whose north is Engger Us Ophiolite Belt and south is Qagan Qulu Ophiolite Belt. The pluton was emplaced into Upper Carboniferous-Lower Permian Amushan Formation. According to the research about the original Carboniferous Amushan Formation, the lower and middle sections of the Carboniferous Amushan Formation consist of volcanic, clastic, and carbonate rocks, interpreted to represent the sedimentary association of a volcanic arc and back-arc basin; the upper section of the Amushan Formation is a molasse composed of silty shale, sandstone, gravel-bearing sandstone, and conglomerate. The Wuliji pluton consists mainly of biotite monzonitic granite, amphibole-bearing biotite monzonitic granite, and monzonitic granite. Geochemical analyses show that the pluton has both metaluminous and peraluminous characteristics, and on average has SiO2>70 wt%, Al2O3 >14 wt%, and high contents of Na2O+K2O (8.5 wt%), which define a calc-alkaline series. In addition, REE patterns show enrichment of LREE and weak negative Eu anomalies (δ Eu=0.3-1). Altogether, the samples are depleted in Nb, Ta, Ti, P, Sr, and Ba, and enriched in Rb, Th, and K. These geochemical traits are interpreted to reflect an arc component. A secondary ion mass spectrometry (SIMS) U-Pb zircon age of the biotite monzonitic Wuliji pluton in the Northern Alxa Region, Inner Mongolia, is 250.8±2.0 Ma (1σ). Samples have ε Nd (t) values between 0.1 and 1.3, which suggests that the granites were derived from mixing between the crust and mantle. Based on the SIMS age and geochemical characteristics, Wuliji granite is interpreted to be a post-collisional granite, the result of mantle-derived melt and assimilated juvenile arc crust. However, according to the newest international stratigraphic classification standard, the upper section of the Amushan Formation is Lower Permian in age, indicating that the back-arc basin had already closed in Early Permian. We conclude that the Paleo-Asian Ocean represented by the Engger Us Ophiolite Belt subducted southward in Late Carboniferous, at the same time that the trench-arc-basin system formed in the Northern Alxa Region. The Paleo-Asian Ocean was closed in Early Permian and the Northern Alxa Region entered a post-collisional period in the Late Permian, as indicated by the Wuliji granites. This suggests that the genesis of the Wuliji granites is consistent with the pluton emplacement at the upper crust, which occurred widely in the northern margin of the North China Plate in Late Carboniferous to Triassic.ZHANG Wen WU TaiRan FENG JiCheng ZHENG RongGuo HE YuanKai 2013Science China Earth Sciences2013,56,1:26

8Breast cancer development and progression:Risk factors,cancer stem cells,signaling pathways,genomics,and molecular pathogenesis显示文摘As the most commonly occurring cancer in women worldwide,breast cancer poses a formidable public health challenge on a global scale.Breast cancer consists of a group of biologically and molecularly heterogeneous diseases originated from the breast.While the risk factors associated with this cancer varies with respect to other cancers,genetic predisposition,most notably mutations in BRCA1 or BRCA2 gene,is an important causative factor for this malignancy.Breast cancers can begin in different areas of the breast,such as the ducts,the lobules,or the tissue in between.Within the large group of diverse breast carcinomas,there are various denoted types of breast cancer based on their invasiveness relative to the primary tumor sites.It is important to distinguish between the various subtypes because they have different prognoses and treatment implications.As there are remarkable parallels between normal development and breast cancer progression at the molecular level,it has been postulated that breast cancer may be derived from mammary cancer stem cells.Normal breast development and mammary stem cells are regulated by several signaling pathways,such as estrogen receptors(ERs),HER2,and Wnt/b-catenin signaling pathways,which control stem cell proliferation,cell death,cell differentiation,and cell motility.Furthermore,emerging evidence indicates that epigenetic regulations and noncoding RNAs may play important roles in breast cancer development and may contribute to the heterogeneity and metastatic aspects of breast cancer,especially for triple-negative breast cancer.This review provides a comprehensive survey of the molecular,cellular and genetic aspects of breast cancer.Yixiao Feng Mia Spezia Shifeng Huang Chengfu Yuan Zongyue Zeng Linghuan Zhang Xiaojuan Ji Wei Liu Bo Huang Wenping Luo Bo Liu Yan Lei Scott Du Akhila Vuppalapati Hue H.Luu Rex C.Haydon Tong-Chuan He Guosheng Ren 2018Genes & Diseases2018,5,2:24
9Presence of Antibodies to Heat Stress Proteins and its Possible Significance in Workers Exposed to High Temperature and Carbon Monoxide显示文摘Antibodies to the ubiquitous group of stress proteins known as heat shock proteins (Hsps) have been found to be associated with a number of diseases in humans. Hsps are known to be induced by certain xenobiotics, some of which are common in the working environment. The biological significance of the presence of such autoantibodies is presently unclear. In the present study, we used immunoblotting to investigate the presence of antibodies against the different stress proteins, Hsp27, Hsp60, Hsp71, Hse (heat shock cognate ) 73 and Hsp89a and D in groups of workers exposed to high temperature or carbon monoxide. These data were related to a detailed clinical evaluation and to various laboratory measurements including electrocardiogram (ECG), B echogram, white blood cell counts and typing, the activity of alanine aminotransferase (ALT), acid phosphatase (ACP) and alkaline phosphatase (ALP) and lymphocyte DNA damage. Antibodies to Hsp27 and Hsp71 were found more frequently in the high temperature and carbon monoxide-exposed groups than in controls (P (0.05 ). The carbon monoxide-exposed group showed the highest incidence of anti-Hsp antibodies. Anti-Hsp60 antibodies were only detected in workers exposed to high temperature or carbon monoxide. The percentage of workers with abnormal ECG, B echogram changes and displaying hepatitis B antigen (HBsAg ) was higher in the carbon monoxide group than in the control group (P<0.05 ).There was a significant inerease in the activity of ALT in the high temperature and carbon monoxide groups and in the activities of ACP and ALP in the carbon monoxide group (P<0.05 ). The extent of DNA damage measured in lymphoeytes was higher in workers from the high temperature and carbon monoxide-cxposed groups. We suggest that the increased frequeney of antibodies to Hsps is the result of these damages, of the release of denatured Hsps and of a decrease in the phagocytic ability of macrophages in these workers. The data gathered in the present study show a statistical relation between the occurrence of antibodies against Hsps and the frequency of health problems in workers and suggest a potential role for the antibodies as useful biomarkers to assess whether workers are experieneing environmentalWU TANG-CHUN TANGUAY, ROBERT M.

15A Chromosome-Scale Genome Assembly of Paper Mulberry(Bmussonetia papyrifera)Provides New Insights into Its Forage and Papermaking Usage显示文摘Paper mulberry(Broussonetia papyrifera)is a well-known woody tree historically used for Cai Lun papermaking,one of the four great inventions of ancient China.More recently,Paper mulberry has also been used as forage to address the shortage of feedstuff because of its digestible crude fiber and high protein contents.In this study,we obtained a chromosome-scale genome assembly for Paper mulberry using integrated approaches,including Illumina and PacBio sequencing platform as well as Hi-C,optical,and genetic maps.The assembled Paper mulberry genome consists of 386.83 Mb,which is close to the estimated size,and 99.25%(383.93 Mb)of the assembly was assigned to 13 pseudochromosomes.Comparative genomic analysis revealed the expansion and contraction in the flavonoid and lignin biosynthetic gene families,respectively,accounting for the enhanced flavonoid and decreased lignin biosynthesis in Paper mulberry.Moreover,the increased ratio of syringyl-lignin to guaiacyl-lignin in Paper mulberry underscores its suitability for use in medicine,forage,papermaking,and barkcloth making.We also identified the rootassociated microbiota of Paper mulberry and found that Pseudomonas and Rhizobia were enriched in its roots and may provide the source of nitrogen for its stems and leaves via symbiotic nitrogen fixation.Collectively,these results suggest that Paper mulberry might have undergone adaptive evolution and recruited nitrogen-fixing microbes to promote growth by enhancing flavonoid production and altering lignin monomer composition.Our study provides significant insights into genetic basis of the usefulness of Paper mulberry in papermaking and barkcloth making,and as forage.These insights will facilitate further domestication and selection as well as industrial utilization of Paper mulberry worldwide.Xianjun Peng Hui Liu Peilin Chen Feng Tang Yanmin Hu Fenfen Wang Zhi Pi Meiling Zhao Naizhi Chen Hui Chen Xiaokang Zhang Xueqing Yan Min Liu Xiaojun Fu Guofeng Zhao Pu Yao Lili Wang He Dai Xuming Li Wei Xiong Wencai Xu Hongkun Zheng Haiyan Yu Shihua Shen 2019Molecular Plant2019,12,5:18
16Wnt and BMP signaling crosstalk in regulating dental stem cells:Implications in dental tissue engineering显示文摘Tooth is a complex hard tissue organ and consists of multiple cell types that are regulated by important signaling pathways such as Wnt and BMP signaling.Serious injuries and/or loss of tooth or periodontal tissues may significantly impact aesthetic appearance,essential oral functions and the quality of life.Regenerative dentistry holds great promise in treating oral/dental disorders.The past decade has witnessed a rapid expansion of our understanding of the biological features of dental stem cells,along with the signaling mechanisms governing stem cell self-renewal and differentiation.In this review,we first summarize the biological characteristics of seven types of dental stem cells,including dental pulp stem cells,stem cells from apical papilla,stem cells from human exfoliated deciduous teeth,dental follicle precursor cells,periodontal ligament stem cells,alveolar bone-derived mesenchymal stem cells(MSCs),and MSCs from gingiva.We then focus on how these stem cells are regulated by bone morphogenetic protein(BMP)and/or Wnt signaling by examining the interplays between these pathways.Lastly,we analyze the current status of dental tissue engineering strategies that utilize oral/dental stem cells by harnessing the interplays between BMP and Wnt pathways.We also highlight the challenges that must be addressed before the dental stem cells may reach any clinical applications.Thus,we can expect to witness significant progresses to be made in regenerative dentistry in the coming decade.Fugui Zhang Jinlin Song Hongmei Zhang Enyi Huang Dongzhe Song Viktor Tollemar Jing Wang Jinhua Wang Maryam Mohammed Qiang Wei Jiaming Fan Junyi Liao Yulong Zou Feng Liu Xue Hu Xiangyang Qu Liqun Chen Xinyi Yu Hue H.Luu Michael J.Lee Tong-Chuan He Ping Ji 2016Genes & Diseases2016,3,4:16

20Characteristics of the microbial communities in the integrated vertical-flow constructed wetlands显示文摘Microorganisms play an important role in removing pollutants from constructed wetlands.We investigated the microbial characteristics in a novel integrated vertical-flow constructed wetland(IVCW) ,which has been in operation in Wuhan,China since 1998.We used phospholipid fatty acid(PLFA) and amoA gene to analyze the structure and diversity of the microbial community within the IVCW.PLFA results suggested that the amount of bacterial PLFA was significantly higher than that of fungal PLFA,but the total microbial biomass represented by PLFA index was low in the system.Microbial spatial distribution showed significantly higher bacterial(both G+and G-) and fungal biomass in the surface than in the subsurface layers.The ratios of monounsaturated to branched PLFA demonstrated that an anaerobic layer sandwiched by two aerobic layers existed in the IVCW,consistent with the redox potential results.Analysis of the amoA revealed the presence of Nitrosomonas-like sequences in the surface substrate of the downflow chamber and apparent diversities of ammonia-oxidizing bacteria in the system.These results suggest that microorganisms,despite their relatively low biomass,have inhabited the IVCW,and the results will offer some valuable information on microbe to system designers and managers.ZHOU Qiaohong,HE Feng,Zhang Liping,WANG Yanfen,WU Zhenbin State Key Laboratory of Freshwater Ecology and Biotechnology,Institute of Hydrobiology,Chinese Academy of Sciences,Wuhan 430072,China Department of Biology and Chemistry,City University of Hong Kong 2009Journal of Environmental Sciences2009,21,9:14
