| 1 | Western North Pacific Tropical Cyclone Database Created by the China Meteorological Administration显示文摘This paper describes the access to, and the content, characteristics, and potential applications of the tropical cyclone(TC) database that is maintained and actively developed by the China Meteorological Administration, with the aim of facilitating its use in scientific research and operational services. This database records data relating to all TCs that have passed through the western North Pacific(WNP) and South China Sea(SCS) since 1949. TC data collection has expanded over recent decades via continuous TC monitoring using remote sensing and specialized field detection techniques,allowing collation of a multi-source TC database for the WNP and SCS that covers a long period, with wide coverage and many observational elements. This database now comprises a wide variety of information related to TCs, such as historical or real-time locations(i.e., best track and landfall), intensity, dynamic and thermal structures, wind strengths, precipitation amounts, and frequency. This database will support ongoing research into the processes and patterns associated with TC climatic activity and TC forecasting. | Xiaoqin LU Hui YU Ming YING Bingke ZHAO Shuai ZHANG Limin LIN Lina BAI Rijin WAN | 2021 | Advances in Atmospheric Sciences2021，38，4： | 96 |
| 2 | Screening and breeding of high taxol producing fungi by genome shuffling显示文摘To apply the fundamental principles of genome shuffling in breeding of taxol-producing fungi, Nodulisporium sylviform was used as starting strain in this work. The procedures of protoplast fusion and genome shuffling were studied. Three hereditarily stable strains with high taxol production were obtained by four cycles of genome shuffling. The qualitative and quantitative analysis of taxol produced was confirmed using thin-layer chromatography (TLC), high performance liquid chromatography (HPLC) and LC-MS. A high taxol producing fungus, Nodulisporium sylviform F4-26, was obtained, which produced 516.37 μg/L taxol. This value is 64.41% higher than that of the starting strain NCEU-1 and 31.52%―44.72% higher than that of the parent strains. | ZHAO Kai, PING WenXiang, ZHANG LiNa, LIU Jun, LIN Yan, JIN Tao & ZHOU DongPo Laboratory of Microbiology, College of Life Science, Heilongjiang University, Harbin 150080, China | 2008 | Science China(Life Sciences)2008，51，3： | 25 |

| 5 | DDIT4 promotes gastric cancer proliferation and tumorigenesis through the p53 and MAPK pathways显示文摘Background:Gastric cancer(GC)is one of the most common malignancies worldwide,particularly in China.DNA damage-inducible transcript 4(DDIT4)is a mammalian target of rapamycin inhibitor and is induced by various cellular stresses;however,its critical role in GC remains poorly understood.The present study aimed to investigate the poten-tial relationship and the underlying mechanism between DDIT4 and GC development.Methods:We used western blotting,real-time polymerase chain reaction,and immunohistochemical or immunoflu-orescence to determine DDIT4 expression in GC cells and tissues.High-content screening,cell counting kit-8 assays,colony formation,and in vivo tumorigenesis assays were performed to evaluate cell proliferation.Flow cytometry was used to investigate cell apoptosis and cell cycle distribution.Results:DDIT4 was upregulated in GC cells and tissue.Furthermore,downregulating DDIT4 in GC cells inhibited proliferation both in vitro and in vivo and increased 5-fluorouracil-induced apoptosis and cell cycle arrest.In contrast,ectopic expression of DDIT4 in normal gastric epithelial cells promoted proliferation and attenuated chemosensitivity.Further analysis indicated that the mitogen-activated protein kinase and p53 signaling pathways were involved in the suppression of proliferation,and increased chemosensitivity upon DDIT4 downregulation.Conclusion:DDIT4 promotes GC proliferation and tumorigenesis,providing new insights into the role of DDIT4 in the tumorigenesis of human GC. | Feng Du Lina Sun Yi Chu Tingyu Li Chao Lei Xin Wang Mingzuo Jiang Yali Min Yuanyuan Lu Xiaodi Zhao Yongzhan Nie Daiming Fan | 2018 | Cancer Communications2018，38，1： | 10 |
| 6 | Normal Structure and Function of Endothecium Chloroplasts Maintained by ZmMs33-Mediated Lipid Biosynthesis in Tapetal Cells Are Critical for Anther Development in Maize显示文摘Genic male sterility(GMS)is critical for heterosis utilization and hybrid seed production.Although GMS mutants and genes have been studied extensively in plants,it has remained unclear whether chloroplast-associated photosynthetic and metabolic activities are involved in the regulation of anther development.In this study,we characterized the function of ZmMs33/ZmGPAT6,which encodes a member of the glycerol-3-phosphate acyltransferase(GPAT)family that catalyzes the first step of the glycerolipid synthetic pathway.We found that normal structure and function of endothecium(En)chloroplasts maintained by ZmMs33-mediated lipid biosynthesis in tapetal cells are crucial for maize anther development.ZmMs33 is expressed mainly in the tapetum at early anther developmental stages and critical for cell proliferation and expansion at late stages.Chloroplasts in En cells of wild-type anthers function as starch storage sites before stage 10 but as photosynthetic factories since stage 10 to enable starch metabolism and carbohydrate supply.Loss of ZmMs33 function inhibits the biosynthesis of glycolipids and phospholipids,which are major components of En chloroplast membranes,and disrupts the development and function of En chloroplasts,resulting in the formation of abnormal En chloroplasts containing numerous starch granules.Further analyses reveal that starch synthesis during the day and starch degradation at night are greatly suppressed in the mutant anthers,leading to carbon starvation and low energy status,as evidenced by low trehalose-6-phosphate content and a reduced ATP/AMP ratio.The energy sensor and inducer of autophagy,SnRK1,was activated to induce early and excessive autophagy,premature PCD,and metabolic reprogramming in tapetal cells,finally arresting the elongation and development of mutant anthers.Taken together,our results not only show that ZmMs33 is required for normal structure and function of En chloroplasts but also reveal that starch metabolism and photosynthetic activities of En chloroplasts at different developmental stages are essential for normal anther development.These findings provide novel insights for understanding how lipid biosynthesis in the tapetum,the structure and function of En chloroplasts,and energy and substance metabolism are coordinated to maintain maize anther development. | Taotao Zhu Ziwen Li Xueli An Yan Long Xiaofeng Xue Ke Xie Biao Ma Danfeng Zhang Yijian Guan Canfang Niu Zhenying Dong Quancan Hou Lina Zhao Suowei Wu Jinping Li Weiwei Jin Xiangyuan Wan | 2020 | Molecular Plant2020，13，11： | 9 |
| 7 | XBP-1u suppresses autophagy by promoting the degradation of FoxO1 in cancer cells显示文摘Autophagy 被激活响应滋养的饥饿维持细胞的精力动态平衡。然而, autophagy 固执地没被激活,它糟糕在机械学的水平被理解。这里,我们报导 FoxO1 的那周转涉及夫酸安饥饿引起的动态 autophagic 过程。X-box-binding protein-1u (XBP-1u ) 由招募在 FoxO1 降级有一个关键角色 FoxO1 到 20S proteasome。另外,由 Ser61 和 Ser176 上的细胞外的调整蛋白质 kinases1/2 (ERK1/2 ) 的 XBP-1u 的 phosphorylation 被发现在夫酸安饥饿之上为在 XBP-1u 和 FoxO1 之间的增加的相互作用批评。而且,引起 FoxO1 的持续水平和 autophagy 的坚持的激活的 XBP-1u 击倒,在房间生存能力导致重要减少。最后,在 XBP-1u 之间的反的关联和 FoxO1 表示同意很好,表示侧面在许多人的癌症纸巾观察了。因此,我们的调查结果连接到 XBP-1u-induced FoxO1 的 autophagy 的动态过程降级。 | Ying Zhao Xue Li Mu-Yan Cai Ke Ma Jing Yang Jingyi Zhou Wan Fu Fu-Zheng Wei Lina Wang Dan Xie Wei-Guo Zhu | 2013 | Cell Research2013，23，4： | 8 |
| 8 | Fate of secondary effluent dissolved organic matter during soil-aquifer treatment显示文摘The reduction of mass and trihalomethane formation potential (THMFP) of dissolved organic matter (DOM) and its fractions from secondary effluent during laboratory-scale soil-aquifer treatment (SAT) soil columns were studied. Reduction in dissolved organic carbon (DOC), absorbance of ultraviolet light at 254 nm (UV-254), biodegradable dissolved organic carbon (BDOC) and nonbiodegradable dis- solved organic carbon (NBDOC) for the bulk DOM averaged 72.35%, 53.98%, 97.49% and 35.33% across the soil columns, respectively. Using XAD-8 and XAD-4 resins, DOM was fractionated into 3 fractions: hydrophobic acid (HPO-A), transphilic acid (TPI-A) and hydrophilic fraction (HPI). HPO-A was removed by 61.06%, TPI-A by 54.86% and HPI by 74.95% as DOC as a consequence of the laboratory-scale SAT, respectively. The reduction of THMFP from HPO-A, TPI-A and HPI was 27.24%, 26.24% and 36.08%, respectively. Proton nuclear magnetic resonance (1H-NMR) spectra revealed that the HPO-A isolated from the secondary effluent contained more aromatic functional groups than the corresponding TPI-A. Fourier-transform infrared (FT-IR) spectrum analysis illustrated that TPI-A had decreased hydrocarbon and increased aromatics content in the SAT columns. Specific ultraviolet light absorbance (SUVA) and specific THMFP for each DOM fraction increased across the soil columns and HPI exhibited greater increase in both than HPO-A and TPI-A. The most problematic THM precursor was found to be HPO-A with its high quantity present in recharged water and high chlorine reactivity. | XUE Shuang ZHAO QingLiang WEI LiangLiang WANG LiNa LIU ZhiGang | 2007 | Chinese Science Bulletin2007，52，18： | 8 |
| 9 | The wheat MYB-related transcription factor TaMYB72 promotes flowering in rice显示文摘Through large-scale transformation analyses, Ta MYB72 was identified as a flowering time regulator in wheat. Ta MYB72 is a MYB family transcription factor localized to the nucleus. Three Ta MYB72 homologs,Ta MYB72-A, Ta MYB72-B and Ta MYB72-D, cloned from hexaploid wheat were mapped to the short arm of the group 6 chromosomes. Under the long-day conditions,over-expression of the Ta MYB72 in rice shortened the flowering time by approximately 12 d. Expression analyses suggest that Ta MYB72 may function through upregulation of florigen genes Hd3 a and RFT1. | Lichao Zhang Guoxiang Liu Jizeng Jia Guangyao Zhao Chuan Xia Lina Zhang Fu Li Qiang Zhang Chunhao Dong Shuangcheng Gao Longzhi Han Xiuping Guo Xin Zhang Jinxia Wu Xu Liu Xiuying Kong | 2016 | Journal of Integrative Plant Biology2016，58，8： | 8 |
| 10 | A Resource for Inactivation of MicroRNAs Using Short Tandem Target Mimic Technology in Model and Crop Plants显示文摘microRNAs (miRNAs)are endogenous small non-coding RNAs that bind to mRNAs and target them for cleavage and/or translational repression,leading to gene silencing.We previously developed short tandem target mimic (STTM)technology to deactivate endogenous miRNAs in Arabidopsis.Here,we created hundreds of STTMs that target both conserved and species-specific miRNAs in Arabidopsis,tomato,rice,and maize,providing a resource for the functional interrogation of miRNAs.We not only revealed the functions of several miRNAs in plant development,but also demonstrated that tissue-specific inactivation of a few miRNAs in rice leads to an increase in grain size without adversely affecting overall plant growth and development.RNA-seq and small RNAseq analyses of STTM156/157 and STTM165/166 transgenic plants revealed the roles of these miRNAs in plant hormone biosynthesis and activation,secondary metabolism,and ion-channel activity-associated electrophysiology,demonstrating that STTM technology is an effective approach for studying miRNA functions.To facilitate the study and application of STTM transgenic plants and to provide a useful platform for storing and sharing of information about miRNA-regulated gene networks,we have established an online Genome Browser (http://gffzzc750bc0108fa4044swxvk9knqp5fx6bcx.ffgz.tsg.suse.edu.cn/designindex2.php) to display the transcriptomic and miRNAomic changes in STTMinduced miRNA knockdown plants. | Ting Peng Mengmeng Qiao Haiping Liu Sachin Teotia Zhanhui Zhang Yafan Zhao Bobo Wang Dongjie Zhao Lina Shi Cui Zhang Brandon Le Kestrel Rogers Chathura Gunasekara Haitang Duan Yiyou Gu Lei Tian Jinfu Nie Jian Qi Fanrong Meng Lan Huang Qinghui Chen Zhenlin Wang Jinshan Tang Xiaoqing Tang Ting Lan Xuemei Chen Hairong Wei Quanzhi Zhao Guiliang Tang | 2018 | Molecular Plant2018，11，11： | 7 |
| 11 | Identification of the anomaly component using BEMD combined with PCA from element concentrations in the Tengchong tin belt, SW China显示文摘Concentration of elements or element groups in a geological body is the result of multiple stages of rockforming and ore-forming geological processes.An ore-forming element group can be identified by PCA(principal component analysis)and be separated into two components using BEMD(bi-dimensional empirical mode decomposition):(1)a high background component which represents the ore-forming background developed in rocks through various geological processes favorable for mineralization(i.e.magmatism,sedimentation and/or metamorphism);(2)the anomaly component which reflects the oreforming anomaly that is overprinted on the high background component developed during mineralization.Anomaly components are used to identify ore-finding targets more effectively than ore-forming element groups.Three steps of data analytical procedures are described in this paper;firstly,the application of PCA to establish the ore-forming element group;secondly,using BEMD on the o re-forming element group to identify the anomaly components created by different types of mineralization processes;and finally,identifying ore-finding targets based on the anomaly components.This method is applied to the Tengchong tin-polymetallic belt to delineate ore-finding targets,where four targets for Sn(W)and three targets for Pb-Zn-Ag-Fe polymetallic mineralization are identified and defined as new areas for further prospecting.It is shown that BEMD combined with PCA can be applied not only in extracting the anomaly component for delineating the ore-finding target,but also in extracting the residual component for identifying its high background zone favorable for mineralization from its oreforming element group. | Yongqing Chen Lina Zhang Binbin Zhao | 2019 | Geoscience Frontiers2019，10，4： | 7 |
| 12 | Development of the triazole-fused pyrimidine derivatives as highly potent and reversible inhibitors of histone lysine specific demethylase1(LSD1/KDM1A)显示文摘Histone lysine specific demethylase 1(LSD1) has been recognized as an important modulator in post-translational process in epigenetics. Dysregulation of LSD1 has been implicated in the development of various cancers. Herein, we report the discovery of the hit compound 8 a(IC50=3.93 μmol/L) and further medicinal chemistry efforts, leading to the generation of compound 15 u(IC50=49 nmol/L, and Ki= 16 nmol/L), which inhibited LSD1 reversibly and competitively with H3 K4 me2, and was selective to LSD1 over MAO-A/B. Docking studies were performed to rationalize the potency ofcompound 15 u. Compound 15 u also showed strong antiproliferative activity against four leukemia cell lines(OCL-AML3, K562, THP-1 and U937) as well as the lymphoma cell line Raji with the IC50 values of 1.79, 1.30, 0.45, 1.22 and 1.40 μmol/L, respectively. In THP-1 cell line, 15 u significantly inhibited colony formation and caused remarkable morphological changes. Compound 15 u induced expression of CD86 and CD11 b in THP-1 cells, confirming its cellular activity and ability of inducing differentiation.The findings further indicate that targeting LSD1 is a promising strategy for AML treatment, the triazolefused pyrimidine derivatives are new scaffolds for the development of LSD1/KDM1 A inhibitors. | Zhonghua Li Lina Ding Zhongrui Li Zhizheng Wang Fengzhi Suo Dandan Shen Taoqian Zhao Xudong Sun Junwei Wang Ying Liu Liying Ma Bing Zhao Pengfei Geng Bin Yu Yichao Zheng Hongmin Liu | 2019 | Acta Pharmaceutica Sinica B2019，9，4： | 6 |

| 14 | In situ synthesis and modification of calcium carbonate nanoparticles via a bobbling method显示文摘Modified calcium carbonate (CaCO3) nanoparticles with cubic- and spindle-like configuration were synthesized in situ by the typical bobbling (gas-liquid-solid) method. The modifiers, such as sodium stearate, octadecyl dihydrogen phosphate (ODP) and oleic acid (OA), were used to obtain hydrophobic nanoparticles. The different modification effects of the modifiers were investigated by measuring the active ratio, whiteness and the contact angle. Moreover, transmission electron microscopy (TEM), X-ray diffraction (XRD) and thermogravimetry analysis (TGA analysis) were employed to characterize the obtained products. A preliminary reaction mechanism was discussed. According to the results, the active ratio of CaCO3 modified by ODP was ca. 99.9% and the value of whiteness was 97.3% when the dosage of modifiers reached 2%. The contact angle was 122.25° for the CaCO3 modified in the presence of sodium stearate, ODP and OA. When modified CaCO3 was filled into PVC, the mechanical properties of products were improved greatly such as rupture intensity, pull intensity and fuse temperature. The compatibility and affinity between the modified CaCO3 nanoparticles and the organic matrixes were greatly improved. | ZHAO LiNa FENG JingDong WANG ZiChen | 2009 | Science China Chemistry2009，52，7： | 5 |
| 15 | Carbothermic reduction of vanadium titanomagnetite with the assistance of sodium carbonate显示文摘The carbothermic reduction of vanadium titanomagnetite concentrate(VTC)with the assistance of Na_(2)CO_(3)was conducted in an argon atmosphere between 1073 and 1473 K.X-ray diffraction and scanning electron microscopy were used to investigate the phase transformations during the reaction.By investigating the reaction between VTC and Na_(2)CO_(3),it was concluded that molten Na_(2)CO_(3)broke the structure of titanomagnetite by combining with the acidic oxides(Fe_(2)O_(3),TiO_(2),Al_(2)O_(3),and SiO_(2))to form a Na-rich melt and release FeO and MgO.Therefore,Na_(2)CO_(3)accelerated the reduction rate.In addition,adding Na_(2)CO_(3)also benefited the agglomeration of iron particles and the slag–metal separation by decreasing the viscosity of the slag.Thus,Na_(2)CO_(3)assisted carbothermic reduction is a promising method for treating VTC at low temperatures. | Luming Chen Yulan Zhen Guohua Zhang Desheng Chen Lina Wang Hongxin Zhao Fancheng Meng Tao Qi | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，2： | 5 |
| 16 | Screen efficiency comparisons of decision tree and neural network algorithms in machine learning assisted drug design显示文摘In view of huge search space in drug design, machine learning has become a powerful method to predict the affinity between small molecular drug and targeting protein with the development of artificial intelligence technology. However, various machine learning algorithms including massive different parameters make the prediction framework choice to be quite difficult. In this work, we took a recent drug design competition(from XtalPi company on the DataCastle platform) as the typical case to find the optimized parameters for different machines learning algorithms and the most effective algorithm. After the parameter optimizations, we compared the typical machine learning methods as decision tree(XGBoost, LightGBM) and artificial neural network(MLP, CNN) with root-mean-square error(RMSE) and coefficient of determination(R^2) evaluation. As a result, decision tree is more effective than the neural network as LightGBM>XGBoost>CNN>MLP in the affinity prediction of the specific drug design problem with ~160000 samples. For a much larger screening task in a more complicated drug design study, the sophisticated neural network model may go beyond the decision tree algorithm after generalization enhancing and overfitting reducing. The advanced machine learning methods could extract more information of protein-ligand bindings than traditional ones and improve the screen efficiency of drug design up to 200–1000 times. | Qiumei Pu Yinghao Li Hong Zhang Haodong Yao Bo Zhang Bingji Hou Lin Li Yuliang Zhao Lina Zhao | 2019 | Science China Chemistry2019，62，4： | 5 |
| 17 | Targeted peptide-Au cluster binds to epidermal growth factor receptor (EGFR) in both active and inactive states: a clue for cancer inhibition through dual pathways显示文摘The epidermal growth factor receptor(EGFR) has become an important target protein in anticancer drug development. Meanwhile, peptide-Au cluster has been proposed as potential targeted nano-drug assembled by targeting peptide. Here, we designed and synthesized a novel peptide-Au cluster as Au_(10)Peptide_5 to target to EGFR. We found Au_(10)Peptide_5 could target to the natural binding sites of all EGFRs at membrane in both active and inactive states by molecular simulations. Its targeted ability was further verified by the co-localization and blocking experiments. We also study the configuration modifications of both active and inactive EGFRs after binding by Au_(10)Peptide_5. For active EGFR, the absorbed Au_(10)Peptide_5 might replace the natural ligand in EGFR endocytosis process. Then, the peptide-Au cluster in endochylema could inhibit the cancer relating enzyme activity including thioredoxin reductase1(TrxR1) and induce the oxidative stress mediated apoptosis in tumor cells. For inactive EGFR, it was retained in inactive state by Au_(10)Peptide_5 binding to inhibit dimerization of EGFR for anticancer. Both pathways might be applied in anticancer drug development based on the theoretical and experimental study here. | Peng Zhang Jiao Zhai Xueyun Gao Hongkang Zhao Wenyong Su Lina Zhao | 2018 | Science Bulletin2018，63，6： | 4 |
| 18 | Primed macrophages directly and specifically reject allografts显示文摘Monocytes and macrophages have long been associated with acute and chronic allograft rejection;this is mediated by their abilities to promote inflammation,kill target cells via antibody-dependent cytotoxicity and modulate adaptive immunity.Our present study showed that allogeneic antigen-primed macrophages acutely rejected skin grafts with specificity after adoptive transfer into MHC-matched immunodeficient mice.The ability of primed macrophages to reject allografts essentially requires the help of CD4^(+) T cells and does not require the help of CD8^(+) T cells.Moreover,the primed,perforin-deficient macrophages rejected the skin grafts in a significantly delayed pattern compared with WT macrophages,indicating that the perforin pathway of the primed macrophages is likely involved in the rejection process.Thus,primed macrophages are endowed with adaptive immunitylike features,such as specificity,with the help of CD4^(+) T cells during the immune response to allografts.The present study challenges our traditional views of macrophage functions and highlights the biological functions of macrophages beyond innate immunity in mammals. | Zhulang Chu Chenming Sun Lina Sun Chang Feng Fan Yang Yanan Xu Yong Zhao | 2020 | Cellular & Molecular Immunology2020，17，3： | 4 |
| 19 | Relationship Between Organ Masses and Basal Metabolic Rate (BMR) in Tree Sparrows (Passer montanus)显示文摘BMR(basal metabolic rate),body mass and organ masses of tree sparrows(Passer montanus) were measured to analyze the correlation between organ masses and BMR in tree sparrows,and to evaluate the underlying physiological causes of difference in BMR. Adult tree sparrows were live-trapped by mist net in Qiqihar City,Heilongjiang Province(47 29'N,124 02'E) . The closed circuit respirometer was used to measure the metabolic rate(MR) ,and controlled the ambient temperature by using a water bath(±0.5℃) . Body masses were measured to the nearest 0.01 g before and after BMR measurements with a Sartorius balance(model BT25S) . The mean value was recorded as body mass. Wet and dry masses of several organs were measured,too. BMR was(4.276± 0.385) mL O 2 /(g h) and mean body mass was(18.522±0.110) g. Since not all the variables were normal distributed,a log 10-transformation of those variables was employed to linearize them,prior to analyses. Simple regression analyses indicated that most organ masses showed a significant high correlation with body mass. Both the small intestine and rectum masses were notable exception to that trend. The body-mass-adjusted residual analysis showed that only the kidney wet mass,brain mass,stomach mass,small mass and rectum wet mass correlated with BMR. In addition,correlations between several organ masses and BMR were observed. Because of the inter-correlations of organ masses,a principal component analysis(PCA) was performed to redefine the morphological variability. The first four components whose eigenvalues were greater than 1 could explain 75.2% variance of BMR. The first component,whose proportion reached 30.19%,was affected mainly by stomach mass,small intestine mass and rectum mass. Therefore,the results supported the hypothesis that BMR was controlled by some 'expensive metabolic' organs. | LI Ming YIN Yajie NIE Chunyu QU Lina ZHNAG Guofa LIANG Yantao ZHAO Xiaoju LIU Jinsong | 2011 | Journal of Northeast Agricultural University(English Edition)2011，18，4： | 4 |
| 20 | Mutant p53 increases exosome-mediated transfer of mi R-21-3p and mi R-769-3p to promote pulmonary metastasis显示文摘Objective: Tumor metastasis is a complex, multistep process that depends on tumor cells and their communication with the tumor microenvironment. A p53 gain-of-function mutant has been shown to enhance the tumorigenesis, invasion, and metastasis abilities of tumor cells. This study aimed to investigate the roles of p53 R273 H mutation in the tumor microenvironment.Methods: The in vitro and in vivo effects of the p53 R273 H mutant on the invasion and metastasis of HCT116 cells were investigated. Exosomes from wild-type and HCT116-TP53(R273 H) cells were cocultured with mouse embryonic fibroblasts(MEFs). The roles of differentially expressed exosomal micro RNAs identified by microarray analysis were investigated. The functions of the p53 R273 H mutant in tumor cells were also investigated via gene expression microarray and quantitative polymerase chain reaction(q PCR) analyses.Results: Introducing p53 R273 H mutant into HCT116 cells significantly potentiated pulmonary metastasis in vivo. In the presence of exosomes derived from HCT116-TP53(R273 H) cells, the exosomes were taken up by MEFs and became activated. Microarray analysis showed that the p53 R273 H mutation increased the exosomal levels of mi R-21-3 p and mi R-769-3 p. Intriguingly, in clinical samples, mi R-21-3 p and mi R-769-3 p levels were significantly higher in patients with a p53 mutation than in those without this mutation. Furthermore, both mi R-21-3 p and mi R-769-3 p activated fibroblasts and exerted a synergistic effect via their target genes on the transforming growth factor-β(TGF-β)/Smad signaling pathway. The activated fibroblasts excreted cytokine TGF-β and may have reciprocally induced cancer cells to undergo epithelial-mesenchymal transition(EMT). Indeed, HCT116-TP53(R273 H) cells showed increased expression of ZEB1 and SNAI2 and decreased transcription of several cell adhesion molecules.Conclusions: The mutant p53-exosomal mi R-21-3 p/mi R-769-3 p-fibroblast-cytokine circuit appears to be responsible for communication between tumor and stromal cells, with exosomal mi RNAs acting as a bridge. mi R-21-3 p and mi R-769-3 p are potential predictive markers of pulmonary metastasis and candidate targets for therapeutic interventions. | Qiang Ju Lina Zhao Jiajia Gao Lanping Zhou Yang Xu Yulin Sun Xiaohang Zhao | 2019 | Chinese Journal of Cancer Research2019，31，3： | 4 |
