| 1 | China National Medical Products Administration approval summary:anlotinib for the treatment of advanced non-small cell lung cancer after two lines of chemotherapy显示文摘Background:On May 8,2018,the China National Medical Products Administration(NMPA)approved anlotinib,an orally administered anti-angiogenesis inhibitor,for the treatment of patients with advanced non-small cell lung can-cer(NSCLC)who have progressed after treatment with two or more lines of prior systemic chemotherapy.Main body of the abstract:China NMPA reviewed and inspected a regional double-blinded,placebo-controlled,Phase III trial comparing the overall survival(OS)of NSCLC patients between the anlotinib and placebo arms.A total of 437 patients were randomized(2:1)to receive either anlotinib(n=294)or placebo(n=143)once daily on a 2-week on and 1-week off schedule.Patients with epidermal growth factor receptor(EGFR)or activating anaplastic lymphoma kinase(ALK)genomic tumor aberrations should have disease progression on NMPA-approved therapy.Anlotinib is the first NMPA-approved drug for patients with advanced NSCLC who have progressed on at least two lines of prior systemic chemotherapies in China.The approval was based on a statistically and clinically significant improvement in median OS with anlotinib(9.46 months)compared with placebo[6.37 months;hazard ratio(HR])=0.70,95%confidence interval(CI)=0.55-0.89;two-sided log-rank P=0.002].The confirmed objective response rate(ORR)was 9.2%in the anlotinib arm and 0.7%in the placebo arm.The median duration of response(DoR)was 4.83 months,with a 95%CI of 3.31-6.97 months.The toxicity profile of anlotinib was consistent with that of known anti-angiogenesis inhibitors.Common adverse drug reactions(ADRs)in anlotinib-treated patients included hypertension(67.4%),hand-foot syndrome(43.9%),hemoptysis(14.0%),thyroid stimulating hormone(TSH)elevation(46.6%),and corrected QT interval(QTc)prolongation(26.2%).Short conclusion:Anlotinib demonstrated a clinically significant OS prolongation as a novel therapeutic option for advanced or metastatic NSCLC following at least two lines of chemotherapy. | Ming Zhou Xiaoyuan Chen Hong Zhang Lin Xia Xin Tong Limin Zou Ruimin Hao Jianhong Pan Xiao Zhao Dongmei Chen Yuanyuan Song Yueli Qi Ling Tang Zhifang Liu Rong Gao Yuankai Shi Zhimin Yang | 2019 | Cancer Communications2019,39,1: | 35 |
| 2 | A novel m6A reader Prrc2a controls oligodendroglial specification and myelination显示文摘While N6-methyladenosine (m6A), the most abundant internal modification in eukaryotic mRNA, is linked to cell differentiation and tissue development, the biological significance of m6A modification in mammalian glial development remains unknown. Here, we identify a novel m6A reader, Prrc2a (Proline rich coiled-coil 2A), which controls oligodendrocyte specification and myelination. Nestin-Cre-mediated knockout of Prrc2a induces significant hypomyelination, decreased lifespan, as well as locomotive and cognitive defects in a mouse model. Further analyses reveal that Prrc2a is involved in oligodendrocyte progenitor cells (OPCs) proliferation and oligodendrocyte fate determination. Accordingly, oligodendroglial-lineage specific deletion of Prrc2a causes a similar phenotype of Nestin-Cre-mediated deletion. Combining transcriptome-wide RNA-seq, m6A-RIP-seq and Prrc2a RIP-seq analysis, we find that Olig2 is a critical downstream target gene of Prrc2a in oligodendrocyte development. Furthermore, Prrc2a stabilizes Olig2 mRNA through binding to a consensus GGACU motif in the Olig2 CDS (coding sequence) in an m6A-dependent manner. Interestingly, we also find that the m6A demethylase, Fto, erases the m6A modification of Olig2 mRNA and promotes its degradation. Together, our results indicate that Prrc2a plays an important role in oligodendrocyte specification through functioning as a novel m6A reader. These findings suggest a new avenue for the development of therapeutic strategies for hypomyelination-related neurological diseases. | Rong Wu Ang Li Baofa Sun Jian-Guang Sun Jinhua Zhang Ting Zhang Yusheng Chen Yujie Xiao Yuhao Gao Qingyang Zhang Jun Ma Xin Yang Yajin Liao Wei-Yi Lai Xiaolong Qi Shukun Wang Yousheng Shu Hai-Lin Wang Fengchao Wang Yun-Gui Yang Zengqiang Yuan | 2019 | Cell Research2019,29,1: | 32 |
| 3 | The Coix Genome Provides Insights into Panicoideae Evolution and Papery Hull Domestication显示文摘Coix is a grass crop domesticated as early as the Neolithic era.It is still widely cultivated for both highly nutritional food and medicinal use.However,the genetic study and breeding of this crop are hindered by the lack of a sequenced genome.Here,we report de novo sequencing and assembly of the 1619-Mb genome of Coix,and annotation of 75.39%repeats and 39629 protein-coding genes.Comparative genomics analysis showed that Coix is more closely related to sorghum than maize,but intriguingly only Coix and maize had a recent genome duplication event,which was not detected in sorghum.We further constructed a genetic map and mapped several important traits,especially the strength of hull.Selection of papery hull(thin:easy dehulling)from the stony hull(thick:difficult dehulling)in wild progenitors was a key step in Coix domestication.The papery hull makes seed easier to process and germinate.Anatomic and global transcriptome analysis revealed that the papery hull is a result of inhibition of cell division and wall biogenesis.We also successfully demonstrated that seed hull pressure resistance is controlled by two major quantitative trait loci(QTLs),which are associated with hull thickness and color,respectively.The two QTLs were further fine mapped within intervals of 250 kb and 146 kb,respectively.These resources provide a platform for evolutionary studies and will facilitate molecular breeding of this important crop. | Chao Guo Yanan Wang Aiguo Yang Jun He Chaowen Xiao Shanhua Lv Fengming Han Yibing Yuan Yuan Yuan Xiaolong Dong Juan Guo YawenYang-Hailan Liu Ningzhi Zuo Yaxi Hu Kangxu Zhao Zhengbo Jiang Xing Wang Tingting Jiang Yaou Sherf Moju Cao Yuan Wang Zhaobo Long Tingzhao Rong Luqi Huang Shufeng Zhou | 2020 | Molecular Plant2020,13,2: | 11 |
| 4 | Spatial pattern of soil organic carbon in desert grasslands of the diluvial-alluvial plains of northern Qilian Mountains显示文摘The soil properties in arid ecosystems are important determinants of vegetation distribution patterns.Soil organic carbon(SOC)content,which is closely related to soil types and the holding capacities of soil water and nutrients,exhibits complex variability in arid desert grasslands;thus,it is essentially an impact factor for the distribution pattern of desert grasslands.In the present study,an investigation was conducted to estimate the spatial pattern of SOC content in desert grasslands and the association with environmental factors in the diluvial-alluvial plains of northern Qilian Mountains.The results showed that the mean values of SOC ranged from 2.76 to 5.80 g/kg in the soil profiles,and decreased with soil depths.The coefficients of variation(CV)of the SOC were high(ranging from 48.83%to 94.67%),which indicated a strong spatial variability.SOC in the desert grasslands of the study region presented a regular spatial distribution,which increased gradually from the northwest to the southeast.The SOC distribution had a pattern linked to elevation,which may be related to the gradient of climate conditions.Soil type and plant community significantly affected the SOC.The SOC had a significant positive relationship with soil moisture(P<0.05);whereas,it had a more significant negative relationship with the soil bulk density(BD)(P<0.01).However,a number of the variations in the SOC could be explained not by the environmental factors involved in this analysis,but rather other factors(such as grazing activity and landscape).The results provide important references for soil carbon storage estimation in this study region.In addition,the SOC association with environmental variables also provides a basis for a sustainable use of the limited grassland resources in the diluvial-alluvial plains of northern Qilian Mountains. | Rong YANG YongZhong SU Min WANG Tao WANG Xiao YANG GuiPing FAN TianChang WU | 2014 | Journal of Arid Land2014,6,2: | 11 |
| 5 | Secretory/releasing proteome-based identification of plasma biomarkers in HBV-associated hepatocellular carcinoma显示文摘For successful therapy, hepatocellular carcinoma (HCC) must be detected at an early stage. Herein, we used a proteomic approach to analyze the secretory/releasing proteome of HCC tissues to identify plasma biomarkers. Serum-free conditioned media (CM) were collected from primary cultures of cancerous tissues and surrounding noncancerous tissues. Proteomic analysis of the CM proteins permitted the identification of 1365 proteins. The enriched molecular functions and biological processes of the CM proteins, such as hydrolase activity and catabolic processes, were consistent with the liver being the most important metabolic organ. Moreover, 19% of the proteins were characterized as extracellular or membrane-bound. For validation, secretory proteins involved in transforming growth factor-β signaling pathways were validated in plasma samples. Alphafetoprotein (AFP), metalloproteinase (MMP)1, osteopontin (OPN), and pregnancy-specific beta-1-glycoprotein (PSG)9 were significantly increased in HCC patients. The overall performance of MMP1 and OPN in the diagnosis of HCC remained greater than that of AFP. In addition, this study represents the first report of MMP1 as a biomarker with a higher sensitivity and specificity than AFP. Thus, this study provides a valuable resource of the HCC secretome with the potential to investigate serological biomarkers. MMP1 and OPN could be used as novel biomarkers for the early detection of HCC and to improve the sensitivity of biomarkers compared with AFP. | YANG Lei RONG WeiQi XIAO Ting ZHANG Ying XU Bin LIU Yu WANG LiMing WU Fan QI Jun ZHAO XiuYing WANG HongXia HAN NaiJun GUO SuPing WU JianXiong GAO YanNing CHENG ShuJun | 2013 | Science China(Life Sciences)2013,56,7: | 9 |
| 6 | Medium-Chain Triglyceride Activated Brown Adipose Tissue and Induced Reduction of Fat Mass in C57BL/6J Mice Fed High-fat Diet显示文摘Objective To investigate activation of brown adipose tissue(BAT) stimulated by medium-chain triglyceride(MCT). Methods 30 Male C57BL/6J obese mice induced by fed high fat diet(HFD) were divided into 2 groups, and fed another HFD with 2% MCT or long-chain triglyceride(LCT) respectively for 12 weeks. Body weight, blood biochemical variables, interscapular brown fat tissue(IBAT) mass, expressions of m RNA and protein of beta 3-adrenergic receptors(β3-AR), uncoupling protein-1(UCP1), hormone sensitive lipase(HSL), protein kinase A(PKA), and adipose triglyceride lipase(ATGL) in IBAT were measured. Results Significant decrease in body weight and body fat mass was observed in MCT group as compared with LCT group(P<0.05) after 12 weeks. Greater increases in IBAT mass was observed in MCT group than in LCT group(P<0.05). Blood TG, TC, LDL-C in MCT group were decreased significantly, meanwhile blood HDL-C, ratio of HDL-C/LDL-C and norepinephrine were increased markedly. Expressions of m RNA and protein of β3-AR, UCP1, PKA, HSL, ATGL in BAT were greater in MCT group than in LCT group(P<0.05). Conclusion Our results suggest that MCT stimulated the activation of BAT, possible via norepinephrine pathway, which might partially contribute to reduction of the body fat mass in obese mice fed high fat diet. | ZHANG Yong XU Qing LIU Ying Hua ZHANG Xin Sheng WANG Jin YU Xiao Ming ZHANG Rong Xin XUE Chao YANG Xue Yan XUE Chang Yong | 2015 | Biomedical and Environmental Sciences2015,28,2: | 8 |

| 8 | Host metabolism dysregulation and cell tropism identification in human airway and alveolar organoids upon SARS-CoV-2 infection显示文摘The coronavirus disease 2019(COVID-19)pandemic is caused by infection with the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),which is spread primary via respiratory droplets and infects the lungs.Currently widely used cell lines and animals are unable to accurately mimic human physiological conditions because of the abnormal status of cell lines(transformed or cancer cells)and species differences between animals and humans.Organoids are stem cell-derived selforganized three-dimensional culture in vitro and model the physiological conditions of natural organs.Here we showed that SARS-CoV-2 infected and extensively replicated in human embryonic stem cells(hESCs)-derived lung organoids,including airway and alveolar organoids which covered the complete infection and spread route for SARS-CoV-2 within lungs.The infected ceils were ciliated,club,and alveolar type 2(AT2)cells,which were sequentially located from the proximal to the distal airway and terminal alveoli,respectively.Additionally,RNA-seq revealed early cell response to virus infection including an unexpected downregulation of the metabolic processes,especially lipid metabolism,in addition to the well-known upregulation of immune response.Further,Remdesivir and a human neutralizing antibody potently inhibited SARS-CoV-2 replication in lung organoids.Therefore,human lung organoids can serve as a pathophysiological model to investigate the underlying mechanism of SARS-CoV-2 infection and to discover and test therapeutic drugs for COVID-19. | Rongjuan Pei Jianqi Feng Yecheng Zhang Hao Sun Lian Li Xuejie Yang Jiangping He Shuqi Xiao Jin Xiong Ying Lin Kun Wen Hongwei Zhou Jiekai Chen Zhili Rong Xinwen Chen | 2021 | Protein & Cell2021,12,9: | 7 |
| 9 | Increased Chondrocyte Apoptosis in Kashin-Beck Disease and Rats Induced by T-2 Toxin and Selenium Deficiency显示文摘Objective To investigate chondrocyte apoptosis and the expression of biochemical markers associated with apoptosis in Kashin-Beck disease(KBD) and in an established T-2 toxin-and selenium(Se) deficiency-induced rat model. Methods Cartilages were collected from the hand phalanges of five patients with KBD and five healthy children. Sprague-Dawley rats were administered a selenium-deficient diet for 4 weeks prior to T-2 toxin exposure. The apoptotic chondrocytes were observed by terminal deoxynucleotidyl transferase d UTP nick end labeling staining. Caspase-3, p53, Bcl-2, and Bax proteins in the cartilages were visualized by immunohistochemistry, their protein levels were determined by Western blotting, and m RNA levels were determined by real-time reverse transcription polymerase chain reaction. Results Increased chondrocyte apoptosis was observed in the cartilages of children with KBD. Increased apoptotic and caspase-3-stained cells were observed in the cartilages of rats fed with normal and Se-deficient diets plus T-2 toxin exposure compared to those in rats fed with normal and Se-deficient diets. Caspase-3, p53, and Bax proteins and m RNA levels were higher, whereas Bcl-2 levels were lower in rats fed with normal or Se-deficiency diets supplemented with T-2 toxin than the corresponding levels in rats fed with normal diet. Conclusion T-2 toxin under a selenium-deficient nutritional status induces chondrocyte death, which emphasizes the role of chondrocyte apoptosis in cartilage damage and progression of KBD. | YANG Hao Jie ZHANG Ying WANG Zhi Lun XUE Sen Hai LI Si Yuan ZHOU Xiao Rong ZHANG Meng FANG Qian WANG Wen Jun CHEN Chen DENG Xiang Hua CHEN Jing Hong | 2017 | Biomedical and Environmental Sciences2017,30,5: | 7 |
| 10 | Detection of Human Bocavirus in Children with Acute Respiratory Tract Infections in Lanzhou and Nanjing,China显示文摘Objective The aim of this study was to explore the prevalent characteristics of HBoV1 and its co-infection.Methods PCR was used to detect HBoV1-DNA(HBoV1) and other viruses.A multivariate logistic regression model was used to explore possibility of co-detected for related viruses.Results The positivity rates in Nanjing and Lanzhou were 9.38%(74/789) and 11.62%(161/1386),respectively(P>0.05).The HBoV1 positive group was younger than negative group(P<0.05).Seasonal differences were noted,with a higher frequency of infection in December and July.HBoV1-positive children [72.34%(169/235)] were co-infected with other respiratory viruses.Multifactorial analysis showed no correlations between HBoV1 and the clinical classification,region,gender,age,or treatment as an outpatient or in a hospital.Correlations were identified between HBoV1 infections with ADV(OR=1.53,95% CI 1.03-2.28),RSV(OR=0.71,95% CI 0.52-0.98),and IFVA(OR=1.77,95% CI 1.00-3.13).Conclusions Presence of HBoV1 in nasopharyngeal aspirates did not correlate with region or gender,although the prevalence of HBoV1 was higher in younger children.There were no correlations between HBoV1 and other variables,except for the season and ADV,RSV,or IFVA infections. | WU Jian Jun JIN Yu LIN Na XIE Zhi Ping YU Jie Mei LI Jin Song CAO Chang Qing YUAN Xin Hui SONG Jin Rong ZHANG Jing ZHAO Yang GAO Xiao Qian DUAN Zhao Jun | 2014 | Biomedical and Environmental Sciences2014,27,11: | 7 |
| 11 | Single-cell Analysis of CAR-T Cell Activation Reveals A Mixed T_H1/T_H2 Response Independent of Differentiation显示文摘The activation mechanism of chimeric antigen receptor (CAR)-engineered T cells may differ substantially from T cells carrying native T cell receptor,but this difference remains poorly understood. We present the first comprehensive portrait of single-cell level transcriptional and cyto-kine signatures of anti-CD19/4-1BB/CD28/CD3ζ CAR-T cells upon antigen-specific stimulation. Both CD4+helper T (TH) cells and CD8+cytotoxic CAR-T cells are equally effective in directly killing target tumor cells and their cytotoxic activity is associated with the elevation of a range of TH1 and TH2 signature cytokines,e.g.,interferon γ,tumor necrotic factor α,interleukin 5 (IL5),and IL13,as confirmed by the expression of master transcription factor genes TBX21 and GATA3. However,rather than conforming to stringent TH1 or TH2 subtypes,single-cell analysis reveals that the predominant response is a highly mixed TH1/TH2 function in the same cell. The reg-ulatory T cell activity,although observed in a small fraction of activated cells,emerges from this hybrid TH1/TH2 population. Granulocyte-macrophage colony stimulating factor (GM-CSF) is pro-duced from the majority of cells regardless of the polarization states,further contrasting CAR-T to classic T cells. Surprisingly,the cytokine response is minimally associated with differentiation status,although all major differentiation subsets such as na?ve,central memory,effector memory,and effector are detected. All these suggest that the activation of CAR-engineered T cells is a canon-ical process that leads to a highly mixed response combining both type 1 and type 2 cytokines together with GM-CSF,supporting the notion that polyfunctional CAR-T cells correlate with objective response of patients in clinical trials. This work provides new insights into the mechanism of CAR activation and implies the necessity for cellular function assays to characterize the quality of CAR-T infusion products and monitor therapeutic responses in patients. | Iva Xhangolli Burak Dura GeeHee Lee Dongjoo Kim Yang Xiao Rong Fan | 2019 | Genomics, Proteomics & Bioinformatics2019,17,2: | 7 |

| 13 | Sporamin suppresses growth of xenografted colorectal carcinoma in athymic BALB/c mice by inhibiting liver β-catenin and vascular endothelial growth factor expression显示文摘BACKGROUND Colorectal cancer(CRC)is the third most common malignancy of the digestive tract and the fifth leading cause of cancer-related mortality in China.Sporamin,a Kunitz-type trypsin inhibitor isolated from sweet potato,is a potential anti-cancer agent with activities against a number of malignant tumor cells in vitro.The liver secretes a myriad of endocrine factors that may facilitate the growth and transformation of tumors in the development of CRC.AIM To investigate the effects of sporamin on liver morphology and biomarkers of xenografted CRC in the liver of athymic BALB/c mice.METHODS Twenty-seven male BALB/c nude mice were randomly divided into control,vehicle,and sporamin groups.Mice in the latter two groups were intraperitoneally xenografted with LoVo colorectal carcinoma cells and intragastrically infused with saline or sporamin(0.5 g/kg body weight/d),respectively,for 3 wk.Hematoxylin and eosin(HE)staining of the sections was performed to observe morphological changes in hepatic tissue and real-time fluorescent quantitative PCR(qPCR)and enzyme-linked immunosorbent assay(ELISA)were used to measure the expression ofβ-catenin and vascular endothelial growth factor(VEGF)in the liver.RESULTS Sporamin significantly reduced the number and weight of tumor nodules formed in the abdominal cavity.Compared with the vehicle group,the mean tumor weight(±SD)in the sporamin group was significantly reduced(0.44±0.10 g vs 0.26±0.15 g)and the total number of tumors decreased from 93 to 55.HE staining showed that enlargement of the nucleus and synthesis of proteins within hepatocytes,as well as infiltration of inflammatory cells into the liver,were attenuated by sporamin.Immunohistochemical staining and ELISA showed that the concentrations ofβ-catenin and VEGF in the liver were significantly reduced by sporamin.Compared with the vehicle group,the expression ofβ-catenin measured in integrated optical density units per area was reduced in the sporamin group(47.29±9.10 vs 26.14±1.72;P=0.003).Expression of VEGF was also reduced after sporamin intervention from 20.78±2.06 in the vehicle group to 15.80±1.09 in the sporamin group(P=0.021).Compared with the vehicle group,the concentration ofβ-catenin decreased from 134.42±22.04 pg/mL to 109.07±9.65 pg/mL after sporamin intervention(P=0.00002).qPCR indicated that compared to the vehicle group,relative mRNA expression ofβ-catenin and VEGF in the liver of mice in the sporamin-treated group was significantly reduced to 71%±1%(P=0.000001)and 23%±7%(P=0.00002),respectively,of the vehicle group levels.CONCLUSION Sporamin down-regulates the expression and secretion ofβ-catenin and VEGF in the liver,which subsequently inhibits the transcription of downstream genes involved in cancer progression and angiogenesis. | Chun Yang Jing-Jie Zhang Xiao-Peng Zhang Rong Xiao Peng-Gao Li | 2019 | World Journal of Gastroenterology2019,25,25: | 5 |
| 14 | Grain nucleation and growth behavior of a Sn-Pb alloy affected by direct current: An in situ investigation显示文摘In situ synchrotron X-ray radiography was used to study the effect of direct current(DC) on the grain nucleation and growth of Sn-50 wt.%Pb alloy. The results showed that applying DC adequately during solidification could effectively enhance the grain nucleation and inhibit its growth. Imaging of comparative experiments with varying DC intensity indicated that the final grain size, determined by the competition between grain nucleation and growth, was sensitively dependent on the DC intensity. It was found that the average grain size was decreased from 1632 to 567 μm with DC density of 1.5 A/mm^2 compared to the case without DC. Beyond this value, raising the current density may cause a significant decrease in the nucleation rate, and thus lead to a coarsening of the grain structure. | Fenfen Yang Zongning Chen Fei Cao Rong Fan Huijun Kang Wanxia Huang Qingxi Yuan Tiqiao Xiao Yanan Fu Tongmin Wang | 2017 | Journal of Materials Science & Technology2017,33,10: | 5 |

| 16 | Cells in G_2/M phase increased in human nasopharyngeal carcinoma cell line by EBV-LMP1 through activation of NF-кB and AP-1显示文摘Although previous studies showed that the principal oncoprotein encoded by Epstein-Barr virus, latent membrane protein 1 (LMP1), could induce the nasopharyngeal carcinoma cells in G2/M phase increased, littleis known about the target molecules and mechanisms. The present study demonstrated that LMP1 couldinduce the accumulation of p53 protein and upregulate its transactivity in a dose dependent manner, whichresulted in the decrease of the kinase activity of cdc2/cyclin B complex and inducing arrest at G2/M phasethrough the activation of NF-kB and AP-1 signaling pathways, and the effect of NF-kB was more obviousthan that of AP-1. This study provided some significant evidence for further elucidating the molecular mechanisms that LMP1 had effects on the surveillance mechanism of cell cycle and promoting the survivalof transformed cells and tumorigenesis. | LIN DENG,JING YANG,XIAO RONG ZHAO,XI YUN DENG,LIANG ZENG,HUAN HUA GU,MIN TANG,YA CAOCancer Research Institute,Xiangya School of Medicine,Central South University,Xiangya Road 88,Chang-sha,Hunan 410078,China | 2003 | Cell Research2003,13,3: | 5 |
| 17 | Post-surgical resection prognostic value of combined OPN, MMP7, and PSG9 plasma biomarkers in hepatocellular carcinoma显示文摘Biomarkers for hepatocellular carcinoma (HCC) following curative resection are not currently sufficient for prognostic indication of overall survival (OS) and disease-free survival (DFS). The aim of this study was to investigate the prognostic performance of osteopontin (OPN), matrix metalloproteinase 7 (MMP7), and pregnancy specific glycoprotein 9 (PSG9) in patients with HCC. A total of 179 prospective patients with HCC provided plasma before hepatectomy. Plasma OPN, MMP7, and PSG9 levels were determined by enzyme-linked immunosorbent assay. Correlations between plasma levels, clinical parameters, and outcomes (OS and DFS) were overall analyzed. High OPN (≥149.97 ng/mL), MMP7 (≥2.28 ng/mL), and PSG9 (≥45.59 ng/mL) were prognostic indicators of reduced OS (P<0.001, P<0.001, and P=0.007, respectively). Plasma PSG9 protein level was an independent factor in predicting OS (P=0.008) and DFS (P=0.038). Plasma OPN+MMP7+PSG9 elevation in combination was a prognostic factor for OS (P<0.001). OPN was demonstrated to be a risk factor-associated OS in stage I patients with HCC and patients with low α-fetoprotein levels (<20 ng/mL). These findings suggested that OPN, MMP7, PSG9 and their combined panels may be useful for aiding in tumor recurrence and mortality risk prediction of patients with HCC, particularly in the early stage of HCC carcinogenesis. | Weiqi Rong Yang Zhang Lei Yang Lin Feng Baojun Wei Fan Wu Liming Wang Yanning Gao Shujun Cheng Jianxiong Wu Ting Xiao | 2019 | Frontiers of Medicine2019,13,2: | 5 |
| 18 | Back-n white neutron source at CSNS and its applications显示文摘Back-streaming neutrons from the spallation target of the China Spallation Neutron Source(CSNS)that emit through the incoming proton channel were exploited to build a white neutron beam facility(the so-called Back-n white neutron source),which was completed in March 2018.The Back-n neutron beam is very intense,at approximately 29107 n/cm2/s at 55 m from the target,and has a nominal proton beam with a power of 100 kW in the CSNS-I phase and a kinetic energy of 1.6 GeV and a thick tungsten target in multiple slices with modest moderation from the cooling water through the slices.In addition,the excellent energy spectrum spanning from 0.5 eV to 200 MeV,and a good time resolution related tothe time-of-flight measurements make it a typical white neutron source for nuclear data measurements;its overall performance is among that of the best white neutron sources in the world.Equipped with advanced spectrometers,detectors,and application utilities,the Back-n facility can serve wide applications,with a focus on neutron-induced cross-sectional measurements.This article presents an overview of the neutron beam characteristics,the experimental setups,and the ongoing applications at Backn. | Jing-Yu Tang Qi An Jiang-Bo Bai Jie Bao Yu Bao Ping Cao Hao-Lei Chen Qi-Ping Chen Yong-Hao Chen Zhen Chen Zeng-Qi Cui Rui-Rui Fan Chang-Qing Feng Ke-Qing Gao Xiao-Long Gao Min-Hao Gu Chang-Cai Han Zi-Jie Han Guo-Zhu He Yong-Cheng He Yang Hong Yi-Wei Hu Han-Xiong Huang Xi-Ru Huang Hao-Yu Jiang Wei Jiang Zhi-Jie Jiang Han-Tao Jing Ling Kang Bo Li Chao Li Jia-Wen Li Qiang Li Xiao Li Yang Li Jie Liu Rong Liu Shu-Bin Liu Xing-Yan Liu Ze Long Guang-Yuan Luan Chang-Jun Ning Meng-Chen Niu Bin-Bin Qi Jie Ren Zhi-Zhou Ren Xi-Chao Ruan Zhao-Hui Song Kang Sun Zhi-Jia Sun Zhi-Xin Tan Xin-Yi Tang Bin-Bin Tian Li-Jiao Wang Peng-Cheng Wang Zhao-Hui Wang Zhong-Wei Wen Xiao-Guang Wu Xuan Wu Li-Kun Xie Xiao-Yun Yang Yi-Wei Yang Han Yi Li Yu Tao Yu Yong-Ji Yu Guo-Hui Zhang Lin-Hao Zhang Qi-Wei Zhang Xian-Peng Zhang Yu-Liang Zhang Zhi-Yong Zhang Lu-Ping Zhou Zhi-Hao Zhou Ke-Jun Zhu 无 | 2021 | Nuclear Science and Techniques2021,32,1: | 4 |
| 19 | Salicylic acid promotes quiescent center cell division through ROS accumulation and down-regulation of PLT1,PLT2,and WOX5显示文摘Salicylic acid(SA)plays a crucial role in plant immunity.However,its function in plant development is poorly understood.The quiescent center(QC),which maintains columella stem cells(CSCs)in the root apical meristem and typically exhibits low levels of cell division,is critical for root growth and development.Here,we show that the Arabidopsis thaliana SA overaccumulation mutant constitutively activated cell death 1(cad1),which exhibits increased cell division in the QC,is rescued by additional mutations in genes encoding the SA biosynthetic enzyme SALICYLIC ACID INDUCTION DEFFICIENT2(SID2)or the SA receptor NONEXPRESSER OF PR GENES1(NPR1),indicating that QC cell division in the cad1 mutant is promoted by the NPR1-dependent SA signaling pathway.The application of exogenous SA also promoted QC cell division in wild-type plants in a dose-dependent manner and largely suppressed the expression of genes involved in QC maintenance,including those encoding the APETALA2(AP2)transcription factors PLETHORA1(PLT1)and PLT2,as well as the homeodomain transcription factor WUSCHEL-RELATED HOMEOBOX5(WOX5).Moreover,we showed that SA promotes reactive oxygen species(ROS)production,which is necessary for the QC cell division phenotype in the cad1 mutant.These results provide insight into the function of SA in QC maintenance. | Zhuqing Wang Duoyan Rong Dixing Chen Yang Xiao Renyi Liu Shuang Wu Chizuko Yamamuro | 2021 | Journal of Integrative Plant Biology2021,63,3: | 4 |
