1Evaluation of Chlorophyll Content and Fluorescence Parameters as Indicators of Drought Tolerance in Barley显示文摘Drought is a major abiotic stress that severely affects food production worldwide. Agronomic and physiological traits associated with drought tolerance are suitable indicators for selection of drought tolerance genotypes to reduce the impact of water deficit on crop yield in breeding program. The objective of this study was to identify indicators related to drought tolerance through analysis of photosynthetic traits in barley (Hordeum vulgare L.). These traits included chlorophyll content, initial fluorescence (Fo), maximum primary yield of photochemistry of photosystem Ⅱ (Fv / Fo) and maximum quantum yield of photosystem II (Fv / Fm). Four genotypes (Tadmor, Arta, Morocco9-75 and WI2291) variable in drought tolerance were used to investigate the correlation between these traits and drought tolerance. The results reflected that all of these traits were affected negatively in the four genotypes at different levels of post-anthesis drought stress, but the decrease in drought tolerant genotypes was much less than that of drought sensitive genotypes. The results further revealed that the components of the photosynthetic apparatus could be damaged significantly in drought sensitive genotypes, while drought tolerant genotypes were relatively less affected. On the other hand, the values of chlorophyll content, Fo, Fv / Fo and Fv / Fm in drought tolerance genotypes were significantly higher than those in drought sensitive genotypes under drought stress. It was concluded that chlorophyll content, Fo, Fv / Fo and Fv / Fm could be considered as reliable indicators in screening barley germplasm for drought tolerance.LI Rong-hua GUO Pei-guo Michael Baum Stefania Grando Salvatore Ceccarelli 2006Agricultural Sciences in China2006,5,10:51
2Down-Regulation of Neurocan Expression in Reactive Astrocytes Promotes Axonal Regeneration and Facilitates the Neurorestorative Effects of Bone Marrow Stromal Cells in the Ischemic Rat Brain显示文摘脑卒中后缺血组织边界形成胶质疤痕,抑制轴突再生。神经蛋白聚糖是一种轴突延长抑制分子,在卒中后胶质疤痕中表达上调。骨髓基质干细胞(BMSCs)可降低胶质疤痕壁的厚度,加速缺血周边区的轴突重塑。为了进一步明确BMSCs在轴突再生中的作用及机制,本文重点研究脑缺血组织中BMSCs对神经蛋白聚糖表达的作用。31只成年雄性Wistar大鼠大脑中动脉阻塞(MCAo)2 h,24 h后从中选择16只给予尾静脉注射3×106鼠BMSCs(BMSCs组),15只注射磷酸盐缓冲生理盐水(对照组)。缺血后8 d处死实验大鼠,免疫染色表明反应性星形胶质细胞是神经蛋白聚糖的原始来源,且BMSCs组缺血半暗带脑组织的神经聚糖表达明显低于对照组,生长相关蛋白43表达高于对照组,这在蛋白印迹分析中得到确认。为了进一步检测BMSCs在星形胶质细胞神经蛋白聚糖表达中的作用,用激光捕获显微切割法从缺血周边区收集单纯的反应性星形胶质细胞。BMSCs组的神经蛋白聚糖基因表达明显下调(n=4/组)。原代培养的星形胶质细胞也表现出相同改变,糖氧剥离的星形胶质细胞再给氧时与BMSCs共培养会抑制神经蛋白聚糖基因的表达上调(n=3/组)。本研究表明BMSCs通过下调梗死周边星形胶质细胞中神经蛋白聚糖的表达来促进轴突再生。LI HONG SHEN YI LI QI GAO SMITA SAVANT-BHONSALE AND MICHAEL CHOPP 2008神经损伤与功能重建2008,3,6:51
3Crustal structure of the northeastern Tibetan plateau,the Ordos block and the Sichuan basin from ambient noise tomography显示文摘We apply ambient noise tomography to significant seismic data resources in a region including the northeastern Tibetan plateau,the Ordos block and the Sichuan basin.The seismic data come from about 160 stations of the provincial broadband digital seismograph networks of China.Ambient noise cross-correlations are performed on the data recorded between 2007 and 2009 and high quality inter-station Rayleigh phase velocity dispersion curves are obtained between periods of 6 s to 35 s.Resulting Rayleigh wave phase velocity maps possess a lateral resolution between 100 km and 200 km.The phase velocities at short periods (<20 s) are lower in the Sichuan basin,the northwest segment of the Ordos block and the Weihe graben,and outline sedimentary deposits.At intermediate and long periods (>25 s),strong high velocity anomalies are observed within the Ordos block and the Sichuan basin and low phase velocities are imaged in the northeastern Tibetan plateau,reflecting the variation of crustal thickness from the Tibetan plateau to the neighboring regions in the east.Crustal and uppermost mantle shear wave velocities vary strongly between the Tibetan plateau,the Sichuan basin and the Ordos block.The Ordos block and the Sichuan basin are dominated by high shear wave velocities in the crust and uppermost mantle.There is a triangle-shaped low velocity zone located in the northeastern Tibetan plateau,whose width narrows towards the eastern margin of the plateau.No low velocity zone is apparent beneath the Qinling orogen,suggesting that mass may not be able to flow eastward through the boundary between the Ordos block and the Sichuan basin in the crust and uppermost mantle.Yong Zheng Yingjie Yang Michael H.

5Bone Morphogenetic Protein (BMP) signaling in development and human diseases显示文摘Bone Morphogenetic Proteins(BMPs)are a group of signaling molecules that belongs to the Transforming Growth Factor-b(TGF-b)superfamily of proteins.Initially discovered for their ability to induce bone formation,BMPs are now known to play crucial roles in all organ systems.BMPs are important in embryogenesis and development,and also in maintenance of adult tissue homeostasis.Mouse knockout models of various components of the BMP signaling pathway result in embryonic lethality or marked defects,highlighting the essential functions of BMPs.In this review,we first outline the basic aspects of BMP signaling and then focus on genetically manipulated mouse knockout models that have helped elucidate the role of BMPs in development.A significant portion of this review is devoted to the prominent human pathologies associated with dysregulated BMP signaling.Richard N.Wang Jordan Green Zhongliang Wang Youlin Deng Min Qiao Michael Peabody Qian Zhang Jixing Ye Zhengjian Yan Sahitya Denduluri Olumuyiwa Idowu Melissa Li Christine Shen Alan Hu Rex C.Haydon Richard Kang James Mok Michael J.Lee Hue L.Luu Lewis L.Shi 2014Genes & Diseases2014,1,1:47
6Active Tectonics of the Longmen Shan Region on the Eastern Margin of the Tibetan Plateau显示文摘有为在在西藏的高原的东方边缘的 theLongmen 掸人的活跃 tectonics 的似地球形状的证据的巨大的数量。我们包括 Wenchuan-Maowen, Beichuan-Yingxiu 和 Pengxian-Guanxian 差错调查了一些典型似地球形状的标记,平台偏移量,陡坡,控制差错的僵绳,右快门山脉,右隧道偏移量,抓住在,粉碎带,和拉开盆。电子自旋共振(ESR ) 和热照明(TL ) 变老用从在沉积的表面下面拿的淤泥的沙被获得。根据这些数据,我们推测推进和走向滑倒的率,和结果显示在高原边缘弄短的 Cenozoictectonic 与插入不到 1.10 mm/aand 的率是次要的率滑倒罢工不到 1.46 mm/a。Longmen 掸人是 NNE-trendingdextral 的一个地区与 6:1-1.3:1 的滑倒剧降比率砍。从 NW 到 SE,戳部件变得更小,而走向滑倒部件变得更大。ZHOU Rongjun LI Yong Alexander L.DENSMORE Michael A.

7Active Tectonics and Erosional Unloading at the Eastern Margin of the Tibetan Plateau显示文摘The eastern margin of the Tibetan Plateau is marked by an extremely steep mountain front with relief of over 5 km. This topography,coupled with abundant Mesozoic thrusts within the margin,explains why tectonic maps of the India-Asia collision typically show the eastern margin as a major thrust zone. Actually,it does not like that. Field observations suggest that the margin is better characterized as a zone of NNE-directed dextral shear with extensive strike-slip faulting and secondary thrusting. The high relief and steep gradients are partially explained by erosional unloading of an elastic lithosphere;the pre-erosion inherited topography may be the inherited Mesozoic thrust belt landscape modified by a component of Cenozoic tectonic shortening.Alexander L.

9Elevated serum alpha fetoprotein levels promote pathological progression of hepatocellular carcinoma显示文摘AIM:To investigate the biological role of alpha fetoprotein (AFP) and its clinical signif icance in carcinogenesis of hepatocellular carcinoma (HCC).METHODS:Clinical analysis of HCC patients and im-munohistochemical examination were conducted to evaluate the relationship between serum AFP level and patient mortality. Confocal microscopy,Western blotting, dimethylthiahzolyl-2,5-diphenyl-tetrazolium bromide,Cell Counting Kit-8 assays and flow cytometry were performed to explore the possible mechanism.RESULTS: Among the 160 HCC patients enrolled in this study,130 patients survived 2 years (81.25%),with a survival rate of 86.8% in AFP < 2 0 μg/L group,88.9% in AFP 20-250 μg/L group,and 69.6% in AFP > 250 μg/L group, demonstrating a higher mortality rate in HCC patients with higher AFP levels. Surgical treatment was benef icial only in patients with low AFP levels.The mortality rate of HCC patients with high AFP levels who were treated surgically was apparently higher than those treated with conservative management.The results of immunohistochemistry showed that AFP and AFP receptor were merely expressed in tissues of HCC patients with positive serum AFP.Consistently,in vitro analysis showed that AFP and AFPS were expressed in HepG2 but not in HLE cells. AFP showed a capability to promote cell growth,and this was more apparent in HepG2 cells,in which the proliferation was increased by 3.5 folds. Cell cycle analysis showed that the percent-age of HepG2 cells in S phase after exposure to AFP was modestly increased.CONCLUSION:HCC patients with higher AFP levels show a higher mortality rate,which appears to be attributable to the growth promoting properties of AFP.Peng Li Shan-Shan Wang Hui Liu Ning Li Michael A McNutt Gang Li Hui-Guo Ding 2011World Journal of Gastroenterology2011,17,41:23

11Discovery of the marine Eocene in the northern South China Sea显示文摘The nature of the Eocene stratigraphy of the South China Sea(SCS)has been a mystery for decades.In the southern SCS,the Eocene system with marine deposits is often considered as representing part of the‘Proto-South China Sea’[1].In the northern SCS,however,the Eocene is dominated by non-marine sequences of South China origin[2],probably also related to the Proto-SCS[3].Zhimin Jian Haiyan Jin Michael A Kaminski Fabricio Ferreira Baohua Li Pai-Sen Yu 2019National Science Review2019,6,5:20
12Adenovirus-mediated gene delivery:Potential applications for gene and cell-based therapies in the new era of personalized medicine显示文摘With rapid advances in understanding molecular pathogenesis of human diseases in the era of genome sciences and systems biology,it is anticipated that increasing numbers of therapeutic genes or targets will become available for targeted therapies.Despite numerous setbacks,efficacious gene and/or cell-based therapies still hold the great promise to revolutionize the clinical management of human diseases.It is wildly recognized that poor gene delivery is the limiting factor for most in vivo gene therapies.There has been a long-lasting interest in using viral vectors,especially adenoviral vectors,to deliver therapeutic genes for the past two decades.Among all currently available viral vectors,adenovirus is the most efficient gene delivery system in a broad range of cell and tissue types.The applications of adenoviral vectors in gene delivery have greatly increased in number and efficiency since their initial development.In fact,among over 2000 gene therapy clinical trials approved worldwide since 1989,a significant portion of the trials have utilized adenoviral vectors.This review aims to provide a comprehensive overview on the characteristics of adenoviral vectors,including adenoviral biology,approaches to engineering adenoviral vectors,and their applications in clinical and preclinical studies with an emphasis in the areas of cancer treatment,vaccination and regenerative medicine.Current challenges and future directions regarding the use of adenoviral vectors are also discussed.It is expected that the continued improvements in adenoviral vectors should provide great opportunities for cell and gene therapies to live up to its enormous potential in personalized medicine.Cody S.Lee Elliot S.Bishop Ruyi Zhang Xinyi Yu Evan M.Farina Shujuan Yan Chen Zhao Zongyue Zeng Yi Shu Xingye Wu Jiayan Lei Yasha Li Wenwen Zhang Chao Yang Ke Wu Ying Wu Sherwin Ho Aravind Athiviraham Michael J.Lee Jennifer Moriatis Wolf Russell R.Reid Tong-Chuan He 2017Genes & Diseases2017,4,2:19
13Single-cell transcriptomics reveals regulators underlying immune cell diversity and immune subtypes associated with prognosis in nasopharyngeal carcinoma显示文摘Nasopharyngeal carcinoma(NPC)is an aggressive malignancy with extremely skewed ethnic and geographic distributions.Increasing evidence indicates that targeting the tumor microenvironment(TME)represents a promising therapeutic approach in NPC,highlighting an urgent need to deepen the understanding of the complex NPC TME.Here,we generated single-cell transcriptome profiles for 7581 malignant cells and 40,285 immune cells from fifteen primary NPC tumors and one normal sample.We revealed malignant signatures capturing intratumoral transcriptional heterogeneity and predicting aggressiveness of malignant cells.Diverse immune cell subtypes were identified,including novel subtypes such as CLEC9A^+dendritic cells(DCs).We further revealed transcriptional regulators underlying immune cell diversity,and cell–cell interaction analyses highlighted promising immunotherapeutic targets in NPC.Moreover,we established the immune subtype-specific signatures,and demonstrated that the signatures of macrophages,plasmacytoid dendritic cells(pDCs),CLEC9A^+DCs,natural killer(NK)cells,and plasma cells were significantly associated with improved survival outcomes in NPC.Taken together,our findings represent a unique resource providing in-depth insights into the cellular heterogeneity of NPC TME and highlight potential biomarkers for anticancer treatment and risk stratification,laying a new foundation for precision therapies in NPC.Yu-Pei Chen Jian-Hua Yin Wen-Fei Li Han-Jie Li Dong-Ping Chen Cui-Juan Zhang Jia-Wei Lv Ya-Qin Wang Xiao-Min Li Jun-Yan Li Pan-Pan Zhang Ying-Qin Li Qing-Mei He Xiao-Jing Yang Yuan Lei Ling-Long Tang Guan-Qun Zhou Yan-Ping Mao Chen Wei Ke-Xu Xiong Hong-Bo Zhang Shi-Da Zhu Yong Hou Ying Sun Michael Dean Ido Amit Kui Wu Dong-Ming Kuang Gui-Bo Li Na Liu Jun Ma 2020Cell Research2020,30,11:19

16The wonders of BMP9:From mesenchymal stem cell differentiation,angiogenesis,neurogenesis,tumorigenesis,and metabolism to regenerative medicine显示文摘Although bone morphogenetic proteins(BMPs)initially showed effective induction of ectopic bone growth in muscle,it has since been determined that these proteins,as members of the TGF-b superfamily,play a diverse and critical array of biological roles.These roles include regulating skeletal and bone formation,angiogenesis,and development and homeostasis of multiple organ systems.Disruptions of the members of the TGF-b/BMP superfamily result in severe skeletal and extra-skeletal irregularities,suggesting high therapeutic potential from understanding this family of BMP proteins.Although it was once one of the least characterized BMPs,BMP9 has revealed itself to have the highest osteogenic potential across numerous experiments both in vitro and in vivo,with recent studies suggesting that the exceptional potency of BMP9 may result from unique signaling pathways that differentiate it from other BMPs.The effectiveness of BMP9 in inducing bone formation was recently revealed in promising experiments that demonstrated efficacy in the repair of critical sized cranial defects as well as compatibility with bone-inducing bio-implants,revealing the great translational promise of BMP9.Furthermore,emerging evidence indicates that,besides its osteogenic activity,BMP9 exerts a broad range of biological functions,including stem cell differentiation,angiogenesis,neurogenesis,tumorigenesis,and metabolism.This review aims to summarize our current understanding of BMP9 across biology and the body.Sami Mostafa Mikhail Pakvasa Elam Coalson Allen Zhu Alex Alverdy Hector Castillo Jiaming Fan Alex Li Yixiao Feng Di Wu Elliott Bishop Scott Du Mia Spezia Alissa Li Ofir Hagag Alison Deng Winny Liu Mingyang Li Sherwin S·Ho Aravind Athiviraham Michael J·Lee Jennifer Moriatis Wolf Guillermo A·Ameer Hue H·Luu Rex C·Haydon Jason Strelzow Kelly Hynes Tong-Chuan He Russell R·Reid 2019Genes & Diseases2019,6,3:15

19Neural EGF-like protein 1(NELL-1):Signaling crosstalk in mesenchymal stem cells and applications in regenerative medicine显示文摘Bone tissue regeneration holds the potential to solve both osteoporosis and large skeletal defects,two problems associated with significant morbidity.The differentiation of mesenchymal stem cells into the osteogenic lineage requires a specific microenvironment and certain osteogenic growth factors.Neural EGF Like-Like molecule 1(NELL-1)is a secreted glycoprotein that has proven,both in vitro and in vivo,to be a potent osteo-inductive factor.Furthermore,it has been shown to repress adipogenic differentiation and inflammation.NELL-1 can work synergistically with other osteogenic factors such as Bone Morphogenic Protein(BMP)2 and9,and has shown promise for use in tissue engineering and as a systemically administered drug for the treatment of osteoporosis.Here we provide a comprehensive up-to-date review on the molecular signaling cascade of NELL-1 in mesenchymal stem cells and potential applications in bone regenerative engineering.Mikhail Pakvasa Alex Alverdy Sami Mostafa Eric Wang Lucy Fu Alexander Li Leonardo Oliveira Aravind Athiviraham Michael J.Lee Jennifer Moriatis Wolf Tong-Chuan He Guillermo A.Ameer Russell R.Reid 2017Genes & Diseases2017,4,3:13
20Spatial-temporal analysis of pulmonary tuberculosis in the northeast of the Yunnan province,People’s Republic of China显示文摘Background:The number of pulmonary tuberculosis(PTB)cases in China ranks third in the world.A continuous increase in cases has recently been recorded in Zhaotong prefecture-level city,which is located in the northeastern part of Yunnan province.This study explored the space-time dynamics of PTB cases in Zhaotong to provide useful information that will help guide policymakers to formulate effective regional prevention and control strategies.Methods:The data on PTB cases were extracted from the nationwide tuberculosis online registration system.Time series and spatial cluster analyses were applied to detect PTB temporal trends and spatial patterns at the town level between 2011 and 2015 in Zhaotong.Three indicators of PTB treatment registration history were used:initial treatment registration rate,re-treatment registration rate,and total PTB registration rate.Results:Seasonal trends were detected with an apparent symptom onset peak during the winter season and a registration peak during the spring season.A most likely cluster and six secondary clusters were identified for the total PTB registration rate,one most likely cluster and five secondary clusters for the initial treatment registration rate,and one most likely cluster for the re-treatment registration rate.The most likely cluster of the three indicators had a similar spatial distribution and size in Zhenxiong County,which is characterised by a poor socio-economic level and the largest population in Yunnan.Conclusion:This study identified temporal and spatial distribution of PTB in a high PTB burden area using existing health data.The results of the study provide useful information on the prevailing epidemiological situation of PTB in Zhaotong and could be used to develop strategies for more effective PTB control at the town level.The cluster that overlapped the three PTB indicators falls within the geographic areas where PTB control efforts should be prioritised.Li Huang Xin-Xu Li Eniola Michael Abe Lin Xu Yao Ruan Chun-Li Cao Shi-Zhu Li 2017Infectious Diseases of Poverty2017,6,1:13
