| 2 | Meningeal lymphatic vessels regulate brain tumor drainage and immunity显示文摘Recent studies have shown that meningeal lymphatic vessels(MLVs),which are located both dorsally and basally beneath the skull,provide a route for draining macromolecules and trafficking immune cells from the central nervous system(CNS)into cervical lymph nodes(CLNs),and thus represent a potential therapeutic target for treating neurodegenerative and neuroinflammatory diseases.However,the roles of MLVs in brain tumor drainage and immunity remain unexplored.Here we show that dorsal MLVs undergo extensive remodeling in mice with intracranial gliomas or metastatic melanomas.RNA-seq analysis of MLV endothelial cells revealed changes in the gene sets involved in lymphatic remodeling,fluid drainage,as well as inflammatory and immunological responses.Disruption of dorsal MLVs alone impaired intratumor fluid drainage and the dissemination of brain tumor cells to deep CLNs(dCLNs).Notably,the dendritic cell(DC)trafficking from intracranial tumor tissues to dCLNs decreased in mice with defective dorsal MLVs,and increased in mice with enhanced dorsal meningeal lymphangiogenesis.Strikingly,disruption of dorsal MLVs alone,without affecting basal MLVs or nasal LVs,significantly reduced the efficacy of combined anti-PD-1/CTLA-4 checkpoint therapy in striatal tumor models.Furthermore,mice bearing tumors overexpressing VEGF-C displayed a better response to anti-PD-1/CTLA-4 combination therapy,and this was abolished by CCL21/CCR7 blockade,suggesting that VEGF-C potentiates checkpoint therapy via the CCL21/CCR7 pathway.Together,the results of our study not only demonstrate the functional aspects of MLVs as classic lymphatic vasculature,but also highlight that they are essential in generating an efficient immune response against brain tumors. | Xueting Hu Qiuping Deng Lu Ma Qingqing Li Yidong Chen Yuhan Liao Fan Zhou Chen Zhang Linlin Shao Jun Feng Tubao He Weihai Ning Yan Kong Yingqing Huo Aibin He Bing Liu Jingjing Zhang Ralf Adams Yulong He Fuchou Tang Xiuwu Bian Jincai Luo | 2020 | Cell Research2020,30,3: | 11 |
| 3 | Transcriptome profiling of the developing postnatal mouse testis using next-generation sequencing显示文摘Mammalian testis development is a complex and highly sophisticated process. To study the dynamic change of normal testis development at the transcriptional level, we investigated mouse testes at three postnatal ages: 6 days postnatal, 4 weeks old, and 10 weeks old, representing infant (PN1), juvenile (PN2), and adult (PN3) stages, respectively. Using ultra high-throughput RNA sequencing (RNA-seq) technology, we obtained 211 million reads with a length of 35 bp. We identified 18837 genes that were expressed in mouse testes, and found that genes expressed at the highest level were involved in spermatogenesis. The gene expression pattern in PN1 was distinct from that in PN2 and PN3, which indicates that spermatogenesis has commenced in PN2. We analyzed a large number of genes related to spermatogenesis and somatic development of the testis, which play important roles at different developmental stages. We also found that the MAPK, Hedgehog, and Wnt signaling pathways were significantly involved at different developmental stages. These findings further our understanding of the molecular mechanisms that regulate testis development. Our study also demonstrates significant advantages of RNA-seq technology for studying transcriptome during development. | GONG Wei PAN LinLin LIN Qiang ZHOU YuanYuan XIN ChengQi YU XiaoMin CUI Peng HU SongNian YU Jun | 2013 | Science China(Life Sciences)2013,56,1: | 8 |
| 4 | A Comprehensive Transcriptomic Analysis of Infant and Adult Mouse Ovary显示文摘Ovary development is a complex process involving numerous genes. A well-developed ovary is essential for females to keep fertility and reproduce offspring. In order to gain a better insight into the molecular mechanisms related to the process of mammalian ovary development,we performed a comparative transcriptomic analysis on ovaries isolated from infant and adult mice by using next-generation sequencing technology(SOLi D). We identified 15,454 and 16,646 transcriptionally active genes at the infant and adult stage, respectively. Among these genes, we also identified 7021 differentially expressed genes. Our analysis suggests that, in general, the adult ovary has a higher level of transcriptomic activity. However, it appears that genes related to primordial follicle development, such as those encoding Figla and Nobox, are more active in the infant ovary,whereas expression of genes vital for follicle development, such as Gdf9, Bmp4 and Bmp15, is upregulated in the adult. These data suggest a dynamic shift in gene expression during ovary development and it is apparent that these changes function to facilitate follicle maturation, when additional functional gene studies are considered. Furthermore, our investigation has also revealed several important functional pathways, such as apoptosis, MAPK and steroid biosynthesis, that appear to be much more active in the adult ovary compared to those of the infant. These findings will provide a solid foundation for future studies on ovary development in mice and other mammals and help to expand our understanding of the complex molecular and cellular events that occur during postnatal ovary development. | Linlin Pan Wei Gong Yuanyuan Zhou Xiaonuan Li Jun Yu Songnian Hu | 2014 | Genomics, Proteomics & Bioinformatics2014,12,5: | 7 |
| 5 | Superior CO2 uptake on nitrogen doped carbonaceous adsorbents from commercial phenolic resin显示文摘In this study,N-doped porous carbons were produced with commercial phenolic resin as the raw material,urea as the nitrogen source and KOH as the activation agent.Different from conventional carbonization-nitriding-activation three-step method,a facile two-step process was explored to produce N-incorporated porous carbons.The as-obtained adsorbents hold superior CO2 uptake,i.e.5.01 and 7.47 mmol/g at 25℃and 0℃under 1 bar,respectively.The synergistic effects of N species on the surface and narrow micropores of the adsorbents decide their CO2 uptake under 25℃and atmospheric pressure.These phenolic resin-derived adsorbents also possess many extremely promising CO2 adsorption features like good recyclability,quick adsorption kinetics,modest heat of adsorption,great selectivity of CO2 over N2 and outstanding dynamic adsorption capacity.Cheap precursor,easy preparation strategy and excellent CO2 adsorption properties make these phenolic resin-derived N-doped carbonaceous adsorbents highly promising in CO2 capture. | Shenfang Liu Linli Rao Pupu Yang Xinyi Wang Linlin Wang Rui Ma Limin Yue Xin Hu | 2020 | Journal of Environmental Sciences2020,32,7: | 6 |

| 7 | Interannual variability of the Antarctic Circumpolar Current strength based on merged altimeter data显示文摘Interannual variability of the Antarctic Circumpolar Current (ACC) strength is studied in stream-coordinate with twenty-year Absolute Dynamic Topography data from satellite altimetry. The stream-coordinate projection method separates the ACC from adjacent subtropical and subpolar gyres, enabling consideration of the zonal asymmetry of the ACC rather than assuming that the ACC is a purely zonal flow. It is shown that the ACC strength has large interannual variations with two recent peaks around 2000 and 2009. The interannual variability appears mainly in the Indo-Pacific sector of the Southern Ocean and the strongest signal is located south of Australia. The intensification of the westerly wind in 1998 and 2008 appears to cause the strengthening of the ACC via baroclinic processes. | ZHANG LinLin SUN Che HU DunXin | 2012 | Chinese Science Bulletin2012,57,16: | 6 |
| 8 | Machine-learning-based high-resolution DOA measurement and robust directional modulation for hybrid analog-digital massive MIMO transceiver显示文摘At hybrid analog-digital(HAD)transceiver,an improved HAD estimation of signal parameters via rotational invariance techniques(ESPRIT),called I-HAD-ESPRIT,is proposed to measure the direction of arrival(DOA)of a desired user,where the phase ambiguity due to HAD structure is dealt with successfully.Subsequently,a machine-learning(ML)framework is proposed to improve the precision of measuring DOA.Meanwhile,we find that the probability density function(PDF)of DOA measurement error(DOAME)can be approximated as a Gaussian distribution by the histogram method in ML.Then,a slightly large training data set(TDS)and a relatively small real-time set(RTS)of DOA are formed to predict the mean and variance of DOA/DOAME in the training stage and real-time stage,respectively.To improve the precisions of DOA/DOAME,three weight combiners are proposed to combine the-maximum-likelihood-learning outputs of TDS and RTS.Using the mean and variance of DOA/DOAME,their PDFs can be given directly,and we propose a robust beamformer for directional modulation(DM)transmitter with HAD by fully exploiting the PDF of DOA/DOAME,especially a robust analog beamformer on RF chain.Simulation results show that:(1)the proposed I-HAD-ESPRIT can achieve the HAD Cramer-Rao lower bound(CRLB);(2)the proposed ML framework performs much better than the corresponding real-time one without training stage;(3)the proposed robust DM transmitter can perform better than the corresponding non-robust ones in terms of secrecy rate. | Zhihong ZHUANG Ling XU Jiayu LI Jinsong HU Linlin SUN Feng SHU Jiangzhou WANG | 2020 | Science China(Information Sciences)2020,63,8: | 5 |
| 9 | Transcriptomic analysis reveals key regulators of mammogenesis and the pregnancy-lactation cycle显示文摘An organ unique to mammals,the mammary gland develops 90%of its mass after birth and experiences the pregnancy-lactation-involution cycle(PL cycle)during reproduction.To understand mammogenesis at the transcriptomic level and using a ribo-minus RNA-seq protocol,we acquired greater than 50 million reads each for the mouse mammary gland during pregnancy(day 12 of pregnancy),lactation(day 14 of lactation),and involution(day 7 of involution).The pregnancy-,lactation-and involution-related sequencing reads were assembled into 17344,10160,and 13739 protein-coding transcripts and1803,828,and 1288 non-coding RNAs(ncRNAs),respectively.Differentially expressed genes(DEGs)were defined in the three samples,which comprised 4843 DEGs(749 up-regulated and 4094 down-regulated)from pregnancy to lactation and4926 DEGs(4706 up-regulated and 220 down-regulated)from lactation to involution.Besides the obvious and substantive upand down-regulation of the DEGs,we observe that lysosomal enzymes were highly expressed and that their expression coincided with milk secretion.Further analysis of transcription factors such as Trps1,Gtf2i,Tcf7l2,Nupr1,Vdr,Rb1,and Aebp1,and ncRNAs such as mir-125b,Let7,mir-146a,and mir-15 has enabled us to identify key regulators in mammary gland development and the PL cycle. | ZHOU YuanYuan GONG Wei XIAO JingFa WU JiaYan PAN LinLin LI XiaoNuan WANG XuMin WANG WeiWei HU SongNian YU Jun | 2014 | Science China(Life Sciences)2014,57,3: | 4 |
| 10 | Chinese herbal medicine compound Yi-Zhi-Hao pellet inhibits replication of influenza virus infection through activation of heme oxygenase-1显示文摘As a leading cause of respiratory disease, influenza A virus(IAV) presents a pandemic threat in annual seasonal outbreaks. Given the limitation of existing anti-influenza therapies, there remains to be a requirement for new drugs. Compound Yi-Zhi-Hao pellet(CYZH) is a famous traditional Chinese medicine(TCM) used in the clinic, whose formula has been recorded in Complication of National Standard for Traditional Chinese Medicine to treat common cold. In this study, we found that CYZH exhibited a broad-spectrum anti-influenza activity and inhibited the expression of viral RNA and proteins in vitro. Mechanistically, CYZH had no inhibitory activities against viral protein hemagglutinin and IAV RNA-dependent RNA polymerase. Instead, it induced activation of erythroid 2-related factor 2(Nrf2) and nuclear factor kappa B(NF-κB), which subsequently upregulated heme oxygenase-1(HO-1) expression.Also, CYZH protected cells from oxidative damage induced by reactive oxygen series. In conclusions,CYZH inhibits IAV replication in vitro, at least partly by activating expression of the Nrf2/HO-1 pathway. | Jinqiu Yin Linlin Ma Huiqiang Wang Haiyan Yan Jin Hu Wen Jiang Yuhuan Li | 2017 | Acta Pharmaceutica Sinica B2017,7,6: | 4 |
| 11 | Overexpression of miR-101 suppresses collagen synthesis by targeting EZH2 in hypertrophic scar fibroblasts显示文摘Background:MicroRNA-101(miR-101)is a tumor suppressor microRNA(miRNA)and its loss is associated with the occurrence and progression of various diseases.However,the biological function and target of miR-101 in the pathogenesis of hypertrophic scars(HS)remains unknown.Methods:We harvested HS and paired normal skin(NS)tissue samples from patients and cultured their fibroblasts(HSF and NSF,respectively).We used quantitative reverse transcriptase polymerase chain reaction(qRT-PCR),fluorescence in situ hybridization(FISH),enzyme-linked immunosorbent assays(ELISA)and Western blot analyses to measure mRNA levels and protein expression of miR-101,enhancer of zeste homolog 2(EZH2),collagen 1 and 3(Col1 and Col3)andα-smooth muscle actin(α-SMA)in different in vitro conditions.We also used RNA sequencing to evaluate the relevant signaling pathways and bioinformatics analysis and dual-luciferase reporter assays to predict miR-101 targets.We utilized a bleomycin-induced fibrosis mouse model in which we injected miR-101 mimics to evaluate collagen deposition in vivo.Results:We found low expression of miR-101 in HS and HSF compared to NS and NSF.Overexpressing miR-101 decreased Col1,Col3 andα-SMA expression in HSF.We detected high expression of EZH2 in HS and HSF.Knockdown of EZH2 decreased Col1,Col3 andα-SMA in HSF.Mechanistically,miR-101 targeted the 3-untranslated region(3UTR)of EZH2,as indicated by the decreased expression of EZH2.Overexpressing EZH2 rescued miR-101-induced collagen repression.MiR-101 mimics effectively suppressed collagen deposition in the bleomycin-induced fibrosis mouse model.Conclusions:Our data reveal that miR-101 targets EZH2 in HS collagen production,providing new insight into the pathological mechanisms underlying HS formation. | Jie Li Yan Li Yunchuan Wang Xiang He Jing Wang Weixia Cai Yanhui Jia Dan Xiao Jian Zhang Ming Zhao Kuo Shen Zichao Li Wenbin Jia Kejia Wang Yue Zhang Linlin Su Huayu Zhu Dahai Hu | 2021 | Burns & Trauma2021,9,1: | 3 |
| 12 | Targeting slug-mediated non-canonical activation of c-Met to overcome chemo-resistance in metastatic ovarian cancer cells显示文摘Metastasis-associated drug resistance accounts for high mortality in ovarian cancer and remains to be a major barrier for effective treatment. In this study, SKOV3/T4, a metastatic subpopulation of ovarian cancer SKOV3 cells, was enriched to explore potential interventions against metastaticassociated drug resistance. Quantitative genomic and functional analyses were performed and found that slug was significantly increased in the SKOV3/T4 subpopulation and contributed to the high resistance of SKOV3/T4. Further studies showed that slug activated c-Met in a ligand-independent manner due to elevated levels of fibronectin and provoked integrin α V function, which was confirmed by the significant correlation of slug and p-Met levels in 121 ovarian cancer patient samples. Intriguingly,c-Met inhibitor(s) exhibited greatly enhanced anti-cancer effects in slug-positive ovarian cancer models both in vitro and in vivo. Additionally, IHC analyses revealed that slug levels were highly correlated with reduced survival of ovarian cancer patients. Taken together, this study not only uncovers the critical roles of slug in drug resistance in ovarian cancer but also highlights a promising therapeutic strategy by targeting the noncanonical activation of c-Met in slug-positive ovarian cancer patients with poor prognosis. | Linlin Chang Yan Hu Yingying Fu Tianyi Zhou Jun You Jiamin Du Lin Zheng Ji Cao Meidan Ying Xiaoyang Dai Dan Su Qiaojun He Hong Zhu Bo Yang | 2019 | Acta Pharmaceutica Sinica B2019,9,3: | 3 |
| 13 | BIGpre: A Quality Assessment Package for Next-Generation Sequencing Data显示文摘The emergence of next-generation sequencing (NGS) technologies has significantly improved sequencing throughput and reduced costs. However, the short read length, duplicate reads and massive volume of data make the data processing much more difficult and complicated than the first-generation sequencing technology. Although there are some software packages developed to assess the data quality, those packages either are not easily available to users or require bioinformatics skills and computer resources. Moreover, almost all the quality assessment software currently available didn't taken into account the sequencing errors when dealing with the duplicate assessment in NGS data. Here, we present a new user-friendly quality assessment software package called BIGpre, which works for both Illumina and 454 platforms. BIGpre contains all the functions of other quality assessment software, such as the correlation between forward and reverse reads, read GC-content distribution, and base Ns quality. More importantly, BIGpre incorporates associated programs to detect and remove duplicate reads after taking sequencing errors into account and trimming low quality reads from raw data as well. BIGpre is primarily written in Perl and integrates graphical capability from the statistics package R. This package produces both tabular and graphical summaries of data quality for sequencing datasets from Illumina and 454 platforms. Processing hundreds of millions reads within minutes, this package provides immediate diagnostic information for user to manipulate sequencing data for downstream analyses. BIGpre is freely available at http://gffzz3d42f7e793a54046hxcfcxnvqn6kw6x5c.ffgz.tsg.suse.edu.cn/. | Tongwu Zhang Yingfeng Luo Kan Liu Linlin Pan Bing Zhang Jun Yu Songnlan Hu | 2011 | Genomics, Proteomics & Bioinformatics2011,9,6: | 3 |
| 14 | CPTA treatment reveals potential transcription factors associated with carotenoid metabolism in flowers of Osmanthus fragrans显示文摘Osmanthus fragrans is one of the top ten traditional flowers in China.It is divided into three different groups according to its color.α-Carotene and β-carotene are the main determinants to distinguish the color differences between three groups.However,the dominant genes and transcription factors involved in carotenoid metabolism remain unclear.CPTA treatment(0.7mmol·L−1)remarkably promoted lycopene,α-carotene and β-carotene contents in flowers.Transcriptome sequencing analysis revealed that CPTA treatment could trigger chain reactions in carotenoid metabolism pathway genes.Four up-regulated and 10 down-regulated transcription factors which have close association with carotenoid variation were significantly induced by CPTA treatment.The up-regulated TFs such as MYB43,MYB123,HSF,were further subjected to transcript expression determination in different cultivars with drastic colors.Among them,transcript expression of four up-regulated TFs coincided with the carotenoid accumulation in different cultivars.We selected up-regulated OfMYB43 to verify its function,which is related to stress tolerance and transcriptional regulation.Transient overexpression of OfMYB43 in O.fragrans flowers showed that it could remarkably promote the expression of PDS,ZISO,LCYE and CCD4,leading to increased accumulation of β-branch carotenoids.OfMYB43 was a potential positive regulator of carotenoid biosynthesis in O.fragrans flowers.This study provides insight into the molecular mechanism of carotenoid metabolism in O.fragrans. | Wan Xi Yanhong He Linlin Zhu Shiyang Hu Shuyi Xiong Yi Zhang Jingjing Zou Hongguo Chen Caiyun Wang Riru Zheng | 2021 | Horticultural Plant Journal2021,7,5: | 3 |
| 15 | Review on observational studies of western tropical Pacific Ocean circulation and climate显示文摘The Western Tropical Pacific(WTP) Ocean holds the largest area of warm water(>28℃) in the world ocean referred to as the Western Pacific Warm Pool(WPWP),which modulates the regional and global climate through strong atmospheric convection and its variability.The WTP is unique in terms of its complex 3-D ocean circulation system and intensive multiscale variability,making it crucial in the water and energy cycle of the global ocean.Great advances have been made in understanding the complexity of the WTP ocean circulation and associated climate impact by the international scientific community since the 1960 s through field experiments.In this study,we review the evolving insight to the 3-D structure and multi-scale variability of the ocean circulation in the WTP and their climatic impacts based on in-situ ocean observations in the past decades,with emphasis on the achievements since 2000.The challenges and open que stions remaining are reviewed as well as future plan for international study of the WTP ocean circulation and climate. | HU Dunxin WANG Fan SPRINTALL Janet WU Lixin RISER Stephen CRAVATTE Sophie GORDON Arnold ZHANG Linlin CHEN Dake ZHOU Hui ANDO Kentaro WANG Jianing LEE Jae-Hak HU Shijian WANG Jing ZHANG Dongxiao FENG Junqiao LIU Lingling VILLANOY Cesar KALUWIN Chalapan QU Tangdong MA Yixin | 2020 | Journal of Oceanology and Limnology2020,38,4: | 3 |
| 16 | Tension-Torsion High-Cycle Fatigue Life Prediction of 2A12-T4 Aluminium Alloy by Considering the Anisotropic Damage:Model, Parameter Identification, and Numerical Implementation显示文摘To consider the anisotropic damage in fatigue, an improved boom-panel model is presented to simulate a representative volume element(RVE) in the framework of continuum damage mechanics. The anisotropic damage state of the RVE is described by the continuity extents of booms and panels, whose damage evolutions are assumed to be isotropic. The numerical implementation is proposed on the basis of damage mechanics and the finite element method. Finally,the approach is applied to the fatigue life prediction of 2A12-T4 aluminium alloy specimen under cyclic loading of tension-torsion. The results indicate a good agreement with the experimental data. | Linlin Sun Miao Zhang Weiping Hu Qingchun Meng | 2016 | Acta Mechanica Solida Sinica2016,29,4: | 2 |
| 17 | Spatiotemporal evolution of C3/C4 vegetation and its controlling factors in southern China since the last glacial maximum显示文摘To date, few research have been reported on the evolution of C3/C4 vegetation in southern China, and the main mechanism influencing the evolution of C3/C4 vegetation is unclear. That makes it difficult for researchers to understand the competition mechanism of C3 and C4 plants under different climate environments and its relationship with the climate factors. It is also not conducive for researchers to assess the influence of future climate change on regional C3/C4 vegetation. Exactly, C3/C4 vegetation change in the regional-scale will have a significant impact on the global carbon cycle and agricultural production.Therefore, it is especially important to reconstruct the evolutionary history of C3/C4 vegetation in southern China and clarify the influencing mechanism of climate change. In this study, we systematically analyzed stable carbon isotope(δ13 C) of the longchain n-alkanes in sediment samples from eight lakes and four peat profiles in southern China, to reconstruct the spatiotemporal evolution of C3/C4 vegetation in these regions since the Last Glacial Maximum(LGM) and to investigate the climate factors that affect the C4 plant abundance change in the research area. The integrated long-chain n-alkane(C27–C33) stable carbon isotope results of samples from Zhanjiang Huguangyan Maar Lake, Xingyun Lake, Lugu Lake and Dingnan peat showed that, from the LGM to the Early Holocene, C4 plant relative abundance exhibited a gradually increasing trend from 21% to 34%. In the Middle Holocene, the C4 plant abundance significantly declined and reached a lowest value of 10%. In space, the C4 plant abundance generally exhibited a gradually declining trend from south to north in the LGM and the Early Holocene, while it showed an opposite trend in the Holocene Climate Optimum(6.0 cal ka BP). It reflected that the main influencing factor on C4 plants spatial distribution was changing from temperature to precipitation. This study indicated that temperature was the dominant factor affecting C4 plant distribution in southern China, however, when the temperature condition was appropriate, an increase in precipitation(especially more spring precipitation) would reduce the competitive advantages of C4 plants. Therefore, the combination of temperature and seasonal precipitation was the important factor that determines the C3/C4 vegetation proportion change in the southern China. Under the premise that the temperature will rise and precipitation will increase in the future, the reduction of a competitive advantage for the C4 plants could affect agricultural production in China. | Linlin CUI Jianfang HU Xu WANG | 2019 | Science China Earth Sciences2019,62,8: | 2 |
| 18 | Functional delivery vehicle of organic nanoparticles in inorganic crystals显示文摘Encapsulation of bioactive substances for extended shelf life and controlled,targeted release is critical for their applications in food and drug delivery.Here,a new method has been developed to encapsulate bioactive molecules in the crystal composites,showing greatly enhanced stability and unique pHtriggered response.Chlorophyll,a model bioactive,is first loaded in shellac nanoparticles via coprecipitation with a high encapsulation efficiency,and then the chlorophyll-loaded nanoparticles are incorporated into calcite crystals grown from a gel media containing the nanoparticles.Under the protection of shellac nanoparticles and calcite crystals,chlorophyll shows excellent stability even under light.Encapsulated chlorophyll could only be released by first dissolving the calcite crystals under acidic condition and then dissolving the shellac nanoparticles under alkaline condition.The unique pHtriggered release mimics the pH change from acidic in the stomach to alkaline in the intestine and is thus well suited for controlled,targeted intestinal release.This work suggests that the crystal composites are an ideal delivery vehicle for the functional design of bioactive molecules. | Linlin Kong Xinyi Jin Dapeng Hu Leyun Feng Dong Chen Hanying Li | 2019 | Chinese Chemical Letters2019,30,12: | 2 |
| 19 | miR-7/TGF-β2 axis sustains acidic tumor microenvironment-induced lung cancer metastasis显示文摘Acidosis,regardless of hypoxia involvement,is recognized as a chronic and harsh tumor microenvironment(TME)that educates malignant cells to thrive and metastasize.Although overwhelming evidence supports an acidic environment as a driver or ubiquitous hallmark of cancer progression,the unrevealed core mechanisms underlying the direct effect of acidification on tumorigenesis have hindered the discovery of novel therapeutic targets and clinical therapy.Here,chemical-induced and transgenic mouse models for colon,liver and lung cancer were established,respectively.miR-7 and TGF-β2 expressions were examined in clinical tissues(n=184).RNA-seq,miRNA-seq,proteomics,biosynthesis analyses and functional studies were performed to validate the mechanisms involved in the acidic TME-induced lung cancer metastasis.Our data show that lung cancer is sensitive to the increased acidification of TME,and acidic TME-induced lung cancer metastasis via inhibition of miR-7-5 p.TGF-β2 is a direct target of miR-7-5 p.The reduced expression of miR-7-5 p subsequently increases the expression of TGF-β2 which enhances the metastatic potential of the lung cancer.Indeed,overexpression of miR-7-5 p reduces the acidic p H-enhanced lung cancer metastasis.Furthermore,the human lung tumor samples also show a reduced miR-7-5 p expression but an elevated level of activated TGF-β2;the expressions of both miR-7-5 p and TGF-β2 are correlated with patients’survival.We are the first to identify the role of the miR-7/TGF-β2 axis in acidic p H-enhanced lung cancer metastasis.Our study not only delineates how acidification directly affects tumorigenesis,but also suggests miR-7 is a novel reliable biomarker for acidic TME and a novel therapeutic target for non-small cell lung cancer(NSCLC)treatment.Our study opens an avenue to explore the p H-sensitive subcellular components as novel therapeutic targets for cancer treatment. | Tao Su Suchao Huang Yanmin Zhang Yajuan Guo Shuwei Zhang Jiaji Guan Mingjing Meng Linxin Liu Caiyan Wang Dihua Yu Hiu-Yee Kwan Zhiying Huang Qiuju Huang Elaine Lai-Han Leung Ming Hu Ying Wang Zhongqiu Liu Linlin Lu | 2022 | Acta Pharmaceutica Sinica B2022,12,2: | 2 |
| 20 | Dynamic features of near-inertial oscillations in the Northwestern Pacific derived from mooring observations from^2015 to 2018显示文摘Near-inertial oscillation is an important physical process transferring surface wind energy into deep ocean.We investigated the near-inertial kinetic energy(NIKE)variability using acoustic Doppler current profiler measurements from a mooring array deployed in the tropical western Pacific Ocean along 130°E at 8.5°N,11°N,12.6°N,15°N,and 17.5°N from September 2015 to January 2018.Spatial features,decay timescales,and significant seasonal variability of the observed NIKE were described.At the mooring sites of 17.5°N,15°N,and 12.6°N,the NIKE peaks occurred in boreal autumn and the NIKE troughs were observed in boreal spring.By contrast,the NIKE at 11°N and 8.5°N showed peaks in winter and troughs in summer.Tropical cyclones and strong wind events played an important role in the emergence of high-NIKE events and explained the seasonality and latitudinal characteristics of the observed NIKE. | HU Shijian LIU Lingling GUAN Cong ZHANG Linlin WANG Jianing WANG Qingye MA Jie WANG Fujun JIA Fan FENG Junqiao LU Xi WANG Fan HU Dunxin | 2020 | Journal of Oceanology and Limnology2020,38,4: | 2 |
