| 1 | Anthropogenic emission inventories in China:a review显示文摘The development of reliable anthropogenic emission inventories is essential for both understanding the sources of air pollution and designing effective air-pollution-control measures in China. However, it is challenging to quantify emissions in China accurately, given the variety of contributing sources, the complexity of the technology mix and the lack of reliable measurements. Over the last two decades,tremendous efforts have been made to improve the accuracy of emission inventories, and significant improvements have been realized. More reliable statistics and survey-based data have been used to reduce the uncertainties in activity rates and technology distributions. Local emission factors and source profiles covering various sources have been measured and reported. Based on these local databases, improved emission inventory models have been developed for power plants, large industrial plants and the residential,transportation and agricultural sectors. In this paper, we review the progress that has been made in developing inventories of anthropogenic emissions in China. We first highlight the major updates that have been made to emission inventory models and the underlying data by source category. We then summarize the sector-based estimates of emissions of different species contained in current inventories. The progress that has been made in the development of model-ready emissions is also presented. Finally, we suggest future directions for further improving the accuracy of emission inventories in China. | Meng Li Huan Liu Guannan Geng Chaopeng Hong Fei Liu Yu Song Dan Tong Bo Zheng Hongyang Cui Hanyang Man Qiang Zhang Kebin He | 2017 | National Science Review2017，4，6： | 100 |
| 2 | Design Theory of Full Face Rock Tunnel Boring Machine Transition Cutter Edge Angle and Its Application显示文摘At present, the inner cutters of a full face rock tunnel boring machine (TBM) and transition cutter edge angles are designed on the basis of indentation test or linear grooving test. The inner and outer edge angles of disc cutters are characterized as symmetric to each other with respect to the cutter edge plane. This design has some practical defects, such as severe eccentric wear and tipping, etc. In this paper, the current design theory of disc cutter edge angle is analyzed, and the characteristics of the rock-breaking movement of disc cutters are studied. The researching results show that the rotational motion of disc cutters with the cutterhead gives rise to the difference between the interactions of inner rock and outer rock with the contact area of disc cutters, with shearing and extrusion on the inner rock and attrition on the outer rock. The wear of disc cutters at the contact area is unbalanced, among which the wear in the largest normal stress area is most apparent. Therefore, a three-dimensional model theory of rock breaking and an edge angle design theory of transition disc cutter are proposed to overcome the flaws of the currently used TBM cutter heads, such as short life span, camber wearing, tipping. And a corresponding equation is established. With reference to a specific construction case, the edge angle of the transition disc cutter has been designed based on the theory. The application of TBM in some practical project proves that the theory has obvious advantages in enhancing disc cutter life, decreasing replacement frequency, and making economic benefits. The proposed research provides a theoretical basis for the design of TBM three-dimensional disc cutters whose rock-breaking operation time can be effectively increased. | ZHANG Zhaohuang MENG Liang SUN Fei | 2013 | Chinese Journal of Mechanical Engineering2013，26，3： | 24 |

| 4 | The cutting-edge progress of immune-checkpoint blockade in lung cancer显示文摘Great advances in immune checkpoint blockade have resulted in a paradigm shift in patients with lung cancer.Immune-checkpoint inhibitor(ICI)treatment,either as monotherapy or combination therapy,has been established as the standard of care for patients with locally advanced/metastatic non-small cell lung cancer without EGFR/ALK alterations or extensive-stage small cell lung cancer.An increasing number of clinical trials are also ongoing to further investigate the role of ICIs in patients with early-stage lung cancer as neoadjuvant or adjuvant therapy.Although PD-L1 expression and tumor mutational burden have been widely studied for patient selection,both of these biomarkers are imperfect.Due to the complex cancer-immune interactions among tumor cells,the tumor microenvironment and host immunity,collaborative efforts are needed to establish a multidimensional immunogram to integrate complementary predictive biomarkers for personalized immunotherapy.Furthermore,as a result of the wide use of ICIs,managing acquired resistance to ICI treatment remains an inevitable challenge.A deeper understanding of the underlying biological mechanisms of acquired resistance to ICIs is helpful to overcome these obstacles.In this review,we describe the cutting-edge progress made in patients with lung cancer,the optimal duration of ICI treatment,ICIs in some special populations,the unique response patterns during ICI treatment,the emerging predictive biomarkers,and our understanding of primary and acquired resistance mechanisms to ICI treatment. | Fei Zhou Meng Qiao Caicun Zhou | 2021 | Cellular & Molecular Immunology2021，18，2： | 21 |
| 5 | Wear Analysis of Disc Cutters of Full Face Rock Tunnel Boring Machine显示文摘Wear is a major factor of disc cutters' failure. No current theory offers a standard for the prediction of disc cutter wear yet. In the field the wear prediction method commonly used is based on the excavation length of tunnel boring machine(TBM) to predict the disc cutter wear and its wear law, considering the location number of each disc cutter on the cutterhead(radius for installation); in theory, there is a prediction method of using arc wear coefficient. However, the preceding two methods have their own errors, with their accuracy being 40% or so and largely relying on the technicians' experience. Therefore, radial wear coefficient, axial wear coefficient and trajectory wear coefficient are defined on the basis of the operating characteristics of TBM. With reference to the installation and characteristics of disc cutters, those coefficients are modified according to penetration, which gives rise to the presentation of comprehensive axial wear coefficient, comprehensive radial wear coefficient and comprehensive trajectory wear coefficient. Calculation and determination of wear coefficients are made with consideration of data from a segment of TBM project(excavation length 173 m). The resulting wear coefficient values, after modification, are adopted to predict the disc cutter wear in the follow-up segment of the TBM project(excavation length of 5621 m). The prediction results show that the disc cutter wear predicted with comprehensive radial wear coefficient and comprehensive trajectory wear coefficient are not only accurate(accuracy 16.12%) but also highly congruous, whereas there is a larger deviation in the prediction with comprehensive axial wear coefficient(accuracy 41%, which is in agreement with the prediction of disc cutters' life in the field). This paper puts forth a new method concerning prediction of life span and wear of TBM disc cutters as well as timing for replacing disc cutters. | ZHANG Zhaohuang MENG Liang SUN Fei | 2014 | Chinese Journal of Mechanical Engineering2014，27，6： | 19 |
| 6 | Transjugular intrahepatic portosystemic shunt vs endoscopic therapy in preventing variceal rebleeding显示文摘AIM:To compare early use of transjugular intrahepatic portosystemic shunt(TIPS) with endoscopic treatment(ET) for the prophylaxis of recurrent variceal bleeding.METHODS:In-patient data were collected from 190 patients between January 2007 and June 2010 who suffured from variceal bleeding.Patients who were older than 75 years;previously received surgical treatment or endoscopic therapy for variceal bleeding;and complicated with hepatic encephalopathy or hepatic cancer,were excluded from this research.Thirty-five cases lost to follow-up were also excluded.Retrospective analysis was done in 126 eligible cases.Among them,64 patients received TIPS(TIPS group) while 62 patients received endoscopic therapy(ET group).The relevant data were collected by patient review or telephone calls.The occurrence of rebleeding,hepatic encephalopathy or other complications,survival rateand cost of treatment were compared between the two groups.RESULTS:During the follow-up period(median,20.7 and 18.7 mo in TIPS and ET groups,respectively),rebleeding from any source occurred in 11 patients in the TIPS group as compared with 31 patients in the ET group(Kaplan-Meier analysis and log-rank test,P = 0.000).Rebleeding rates at any time point(6 wk,1 year and 2 year) in the TIPS group were lower than in the ET group(Bonferroni correction α' = α/3).Eight patients in the TIPS group and 16 in the ET group died with the cumulative survival rates of 80.6% and 64.9%(Kaplan-Meier analysis and log-rank test c2 = 4.864,P = 0.02),respectively.There was no significant difference between the two groups with respect to 6-wk survival rates(Bonferroni correction α' = α/3).However,significant differences were observed between the two groups in the 1-year survival rates(92% and 79%) and the 2-year survival rates(89% and 64.9%)(Bonferroni correction α' = α/3).No significant differences were observed between the two treatment groups in the occurrence of hepatic encephalopathy(12 patients in TIPS group and 5 in ET group,KaplanMeier analysis and log-rank test,c2 = 3.103,P = 0.08).The average total cost for the TIPS group was higher than for ET group(Wilcxon-Mann Whitney test,52 678 RMB vs 38 844 RMB,P < 0.05),but hospitalization frequency and hospital stay during follow-up period were lower(Wilcxon-Mann Whitney test,0.4 d vs 1.3 d,P = 0.01;5 d vs 19 d,P < 0.05).CONCLUSION:Early use of TIPS is more effective than endoscopic treatment in preventing variceal rebleeding and improving survival rate,and does not increase occurrence of hepatic encephalopathy. | Hui Xue Meng Zhang Jack XQ Pang Fei Yan Ying-Chao Li Liang-Shan Lv Jia Yuan Muna Palikhe Wei-Zhi Li Zhi-Lun Wang | 2012 | World Journal of Gastroenterology2012，18，48： | 17 |
| 7 | Rock deformation equations and application to the study on slantingly installed disc cutter显示文摘At present the mechanical model of the interaction between a disc cutter and rock mainly concerns indentation experiment, linear cutting experiment and tunnel boring machine(TBM) on-site data. This is not in line with the actual rock-breaking movement of the disc cutter and impedes to some extent the research on the rock-breaking mechanism,wear mechanism and design theory. Therefore, our study focuses on the interaction between the slantingly installed disc cutter and rock, developing a model in accordance with the actual rock-breaking movement. Displacement equations are established through an analysis of the velocity vector at the rock-breaking point of the disc cutter blade; the functional relationship between the displacement parameters at the rock-breaking point and its rectangular coordinates is established through an analysis of micro-displacement vectors at the rock-breaking point, thus leading to the geometric equations of rock deformation caused by the slantingly installed disc cutter. Considering the basically linear relationship between the cutting force of disc cutters and the rock deformation before and after the leap break of rock, we express the constitutive relations of rock deformation as generalized Hooke's law and analyze the effect of the slanting installation angle of disc cutters on the rock-breaking force. This will, as we hope, make groundbreaking contributions to the development of the design theory and installation practice of TBM. | Zhao-Huang Zhang Liang Meng Fei Sun | 2014 | Acta Mechanica Sinica2014，30，4： | 16 |
| 8 | Bone marrow mesenchymal stem cells repair spinal cord ischemia/reperfusion injury by promoting axonal growth and anti-autophagy显示文摘Bone marrow mesenchymal stem cells can differentiate into neurons and astrocytes after transplantation in the spinal cord of rats with ischemia/reperfusion injury. Although bone marrow mesenchymal stem cells are known to protect against spinal cord ischemia/reperfusion injury through anti-apoptotic effects, the precise mechanisms remain unclear. In the present study, bone marrow mesenchymal stem cells were cultured and proliferated, then transplanted into rats with ischemia/reperfusion injury via retro-orbital injection. Immunohistochemistry and immunofluorescence with subsequent quantification revealed that the expression of the axonal regeneration marker, growth associated protein-43, and the neuronal marker, microtubule-associated protein 2, significantly increased in rats with bone marrow mesenchymal stem cell transplantation compared with those in rats with spinal cord ischemia/reperfusion injury. Furthermore, the expression of the autophagy marker, microtubule-associated protein light chain 3B, and Beclin 1, was significantly reduced in rats with the bone marrow mesenchymal stem cell transplantation compared with those in rats with spinal cord ischemia/reperfusion injury. Western blot analysis showed that the expression of growth associated protein-43 and neurofilament-H increased but light chain 3B and Beclin 1 decreased in rats with the bone marrow mesenchymal stem cell transplantation. Our results therefore suggest that bone marrow mesenchymal stem cell transplantation promotes neurite growth and regeneration and prevents autophagy. These responses may likely be mechanisms underlying the protective effect of bone marrow mesenchymal stem cells against spinal cord ischemia/reperfusion injury. | Fei Yin Chunyang Meng Rifeng Lu Lei Li Ying Zhang Hao Chen Yonggang Qin Li Guo | 2014 | Neural Regeneration Research2014，9，18： | 16 |
| 9 | Validation of a Critical Nitrogen Curve for Summer Maize in the North China Plain显示文摘The concept of critical N concentration(N_c)has been widely used in agronomy as the basis for diagnosis of crop N status,and allows discrimination between field situations of sub-optimal and supra-optimal N supply.A critical N dilution curve of N_c=34.0W^(-0.37),where W is the aboveground biomass(Mg DM ha^(-1))and N_c the critical N concentration in aboveground dry matter(g kg^(-1)DM),was developed for spring maize in Europe.Our objectives were to validate whether this European critical N dilution curve was appropriate for summer maize production in the North China Plain(NCP)and to develop a critical N dilution curve especially for summer maize production in this region.In total 231 data points from 16 experiments were used to test the European critical N dilution curve.These observations showed that the European critical N dilution curve was unsuitable for summer maize in the NCP,especially at the early growth stage.From the data obtained,a critical N dilution curve for summer maize in the NCP was described by the equation of N_c=27.2W^(-0,27),when aboveground biomass was between 0.64 and 11.17 Mg DM ha^(-1).Based on this curve,more than 90%of the data for the N deficiency supply treatments had an N nutrition index(NNI)<1 and 92%of the data for the N excess supply treatments had an NNI>1. | YUE Shan-Chao SUN Fu-Lai MENG Qing-Feng ZHAO Rong-Fang LI Fei CHEN Xin-Ping ZHANG Fu-Suo CUI Zhen-Ling | 2014 | Pedosphere2014，24，1： | 13 |
| 10 | Autophagy inhibition enhances apigenin-induced apoptosis in human breast cancer cells显示文摘Apigenin (4',5,7-trihydroxyflavone) is a member of the flavone subclass of flavonoids present in fruits and vegetables. The involvement of autophagy in the apigenin-induced apoptotic death of human breast cancer cells was investigated. Cell proliferation and viability were assessed by 3-(4,5-dimethylthiazol- 2-yl)-2,5-diphenyltetrazolium bromide (MTT) and clonogenic assays. Flow cytometry, fluorescent staining and Western blot analysis were employed to detect apoptosis and autophagy, and the role of autophagy was assessed using autophagy inhibitors. Apigenin dose- and time-dependently repressed the proliferation and clonogenic survival of the human breast cancer T47D and MDA-MB-231 cell lines. The death of T47D and MDA-MB-231 cells was due to apoptosis associated with increased levels of Caspase3, PARP cleavage and Bax/Bcl-2 ratios. The results from flow cytometry and fluorescent staining also verified the occurrence of apoptosis. In addition, the apigenin-treated cells exhibited autophagy, as characterized by the appearance of autophagosomes under fluorescence microscopy and the accumulation of acidic vesicular organelles (AVOs) by flow cytometry. Furthermore, the results of the Western blot analysis revealed that the level of LC3-II, the processed form of LC3-I, was increased. Treatment with the autophagy inhibitor, 3-methyladenine (3-MA), significantly enhanced the apoptosis induced by apigenin, which was accompanied by an increase in the level of PARP cleavage. Similar results were also confirmed by flow cytometry and fluorescence microscopy. These results indicate that apigenin has apoptosis-and autophagy-inducing effects in breast cancer cells. Autophagy plays a cyto-protective role in apigenin-induced apoptosis, and the combination of apigenin and an autophagy inhibitor may be a promising strategy for breast cancer control. | Xuchen Cao Bowen Liu Wenfeng Cao Weiran Zhang Fei Zhang Hongmeng Zhao Ran Meng Lin Zhang Ruifang Niu Xishan Hao Bin Zhang | 2013 | Chinese Journal of Cancer Research2013，25，2： | 12 |
| 11 | Toripalimab combined with lenvatinib and GEMOX is a promising regimen as first-line treatment for advanced intrahepatic cholangiocarcinoma:a single-center,single-arm,phase 2 study显示文摘Advanced intrahepatic cholangiocarcinoma(ICC)has a dismal prognosis.Here,we report the efficacy and safety of combining toripalimab,lenvatinib,and gemcitabine plus oxaliplatin(GEMOX)as first-line therapy for advanced ICC.Thirty patients with pathologically confirmed advanced ICC received intravenous gemcitabine(1 g/m2)on Days 1 and 8 and oxaliplatin(85 mg/m2)Q3W for six cycles along with intravenous toripalimab(240 mg)Q3W and oral lenvatinib(8 mg)once daily for one year.The expression of programmed death-ligand 1(PD-L1)and genetic status was investigated in paraffin-embedded tissues using immunohistochemistry and whole-exome sequencing(WES)analysis.The primary endpoint was the objective response rate(ORR).Secondary outcomes included safety,overall survival(OS),progression-free survival(PFS),disease control rate(DCR)and duration of response(DoR).As of July 1,2022,the median follow-up time was 23.5 months,and the ORR was 80%.Twenty-three patients achieved partial response,and one achieved complete response.Patients(21/30)with DNA damage response(DDR)-related gene mutations showed a higher ORR,while patients(14/30)with tumor area positivity≥1(PD-L1 staining)showed a trend of high ORR,but without significant difference.The median OS,PFS,and DoR were 22.5,10.2,and 11.0 months,respectively.The DCR was 93.3%.Further,56.7%of patients experienced manageable grade≥3 adverse events(AEs),commonly neutropenia(40.0%)and leukocytopenia(23.3%).In conclusion,toripalimab plus lenvatinib and GEMOX are promising first-line regimens for the treatment of advanced ICC.A phase-III,multicenter,double-blinded,randomized study to validate our findings was approved by the National Medical Products Administration(NMPA,No.2021LP01825). | Guo-Ming Shi Xiao-Yong Huang Dong Wu Hui-Chuan Sun Fei Liang Yuan Ji Yi Chen Guo-Huan Yang Jia-Cheng Lu Xian-Long Meng Xin-Ying Wang Lei Sun Ning-Ling Ge Xiao-Wu Huang Shuang-Jian Qiu Xin-Rong Yang Qiang Gao Yi-Feng He Yang Xu Jian Sun Zheng-Gang Ren Jia Fan Jian Zhou | 2023 | Signal Transduction and Targeted Therapy2023，8，4： | 12 |

| 13 | Seven-day triple therapy is a better choice for Helicobacter pylori eradication in regions with low antibiotic resistance显示文摘AIM: To investigate whether 7-d triple therapies are still valid in populations with low levels of resistance.METHODS: A total of 1106 Helicobacter pylori(H. pylori)-positive patients were divided into three groups,each of which received one type of 7-d triple therapy. Therapeutic outcomes of the patients were assessed by the 13C-urea breath test at 8 wk after treatment. The susceptibility of H. pylori to antibiotics was determined by an agar-dilution method. Data analysis was performed by χ2 tests.RESULTS: The eradication rates in groups A,B and C were 90.71%(332/366),90.46%(313/346) and 90.87%(189/208),respectively(P = 0.986). The resistance rates were 8.91% for clarithromycin,14.78% for levofloxacin and 0% for amoxicillin. The eradication rate was significantly different between clarithromycin-and levofloxacin-resistant patients(P < 0.05) in group A. Patients whose treatment failed in group A also had a higher clarithromycin resistance rate than did successive patients(P = 0.034). However,levofloxacin resistance had no obvious influence on the eradication rate. Furthermore,three main antibiotics(clarithromycin,levofloxacin and amoxicillin) had lower DID(defined daily dose per 1000 inhabitants per day) in this city.CONCLUSION: Clarithromycin resistance is the main reason for the failure of 7-d triple therapy. In populations with low levels of resistance,a 7-d triple therapy is a viable choice. The choice of therapy should not be influenced by conditions in high antibiotic resistance regions. | Yue-Feng Tong Jun Lv Li-Yuan Ying Fang Xu Bo Qin Ming-Tong Chen Fei Meng Miao-Ying Tu Ning-Min Yang You-Ming Li Jian-Zhong Zhang | 2015 | World Journal of Gastroenterology2015，21，46： | 12 |
| 14 | Evaluation of a New Real-time PCR Assay for Detection of Mycoplasma Pneumoniae in Clinical Specimens显示文摘Objective To establish and evaluate a real-time PCR assay to detect Mycoplasma pneumoniae (M.pneumoniae) in clinical specimens.Methods By analysing the whole p1 gene sequence of 60 M.pneumoniae clinical isolates in Beijing of China,an optimized real-time PCR assay (MpP1) using p1 gene conserved region was designed.The specificity and sensitivity of this assay were evaluated and compared with other two reported assays (RepMp1 and Mp181) using 40 positive and 100 negative clinical specimens.Results The detection limit of the new assay was 8.1 fg (about 1~3CFU) M.pneumoniae DNA.The sensitivity of MpP1,RepMp1,and Mp181 assays appeared to be 100%,100%,and 85%,respectively.Conclusion MpP1 assay is suitable for the detection of M.pneumoniae in Chinese clinical specimens. | ZHAO Fei CAO Bin HE Li Hua YIN Yu Dong TAO Xiao Xia SONG Shu Fan MENG Fan Liang ZHANG Jian Zhong | 2012 | Biomedical and Environmental Sciences2012，25，1： | 11 |
| 15 | Effect of steam-flaking on chemical compositions,starch gelatinization,in vitro fermentability,and energetic values of maize,wheat and rice显示文摘Intact and steam-flaked grains of maize,wheat and rice(with whole hulls) were analyzed for chemical composition,starch gelatinization degree(SGD) and in vitro fermentation characteristics to investigate the influence of cereal type and steam-flaking(SF) processing on their nutritive values.The treatments were arranged in a 3×2 factorial design.Obvious differences(P<0.001) in chemical composition and energetic values were observed among the different cereal types.SGD and gas production(GP) rate was significantly increased(P<0.001) by SF processing.SF processing also increased(P<0.01) the proportion of propionic acid and decreased the acetic:propionic acid ratio in vitro.Steam-flaking also increased organic matter digestibility and the energetic value of the cereal grains,especially rice.Based on these results,rice probably is more amendable to SF processing than maize and wheat.In conclusion,it is feasible to partially substitute maize grain with wheat or rice in ruminant diets,and steam-flaking can significantly improve the nutritional value of wheat and rice grains. | QIAO Fu-qiang WANG Fei REN Li-ping ZHOU Zhen-ming MENG Qing-xiang BAO Yu-hong | 2015 | Journal of Integrative Agriculture2015，14，5： | 11 |

| 18 | Is tailored therapy based on antibiotic susceptibility effective?A multicenter,open-label,randomized trial显示文摘An effective eradication therapy of Helicobacter pylori(H.pylori)should be used for the first time.In this study,we assessed whether tailored therapy based on antibiotic susceptibility testing is more effective than traditional therapy.We also evaluated the factors that cause treatment failure in high-resistance areas.For this multicenter trial,we recruited 467 H.pylori-positive patients.The patients were randomly assigned to receive tailored triple therapy(TATT),tailored bismuth-containing quadruple therapy(TABQT),or traditional bismuthcontaining quadruple therapy(TRBQT).For the TATT and TABQT groups,antibiotic selection proceeded via susceptibility testing using an agar-dilution test.The patients in the TRBQT group were given amoxicillin,clarithromycin,esomeprazole,and bismuth.Successful eradication was defined as a negative 13C-urea breath test at least eight weeks after the treatment ended.Susceptibility testing was conducted using an agar-dilution test.The eradication rate was examined via intention-to-treat(ITT)and per-protocol(PP)analyses.The clarithromycin,levofloxacin,and metronidazole resistance rates were 26.12%,28.69%,and 96.79%,respectively.Resistance against amoxicillin and furazolidone was rare.The eradication rates for TATT,TRBQT,and TABQT were 67.32%,63.69%,and 85.99%in the ITT analysis(P<0.001)and 74.64%,68.49%,and 91.22%in the PP analysis(P<0.001),respectively.The efficacy of TABQTwas affected by clarithromycin resistance,and bismuth exerted a direct influence on TATT failure.TABQT was the most efficacious regimen for use in high-resistance regions,especially among clarithromycin-susceptible patients. | Jie Pan Zhengchao Shi Dingsai Lin Ningmin Yang Fei Meng Lang Lin Zhencheng Jin Qingjie Zhou Jiansheng Wu Jianzhong Zhang Youming Li | 2020 | Frontiers of Medicine2020，14，1： | 10 |
| 19 | Oncogenic AURKA-enhanced N6-methyladenosine modification increases DROSHA mRNA stability to transactivate STC1 in breast cancer stem-like cells显示文摘RNase III DROSHA is upregulated in multiple cancers and contributes to tumor progression by hitherto unclear mechanisms.Here,we demonstrate that DROSHA interacts withβ-Catenin to transactivate STC1 in an RNA cleavage-independent manner,contributing to breast cancer stem-like cell(BCSC)properties.DROSHA mRNA stability is enhanced by N6-methyladenosine(m^(6)A)modification which is activated by AURKA in BCSCs.AURKA stabilizes METTL14 by inhibiting its ubiquitylation and degradation to promote DROSHA mRNA methylation.Moreover,binding of AURKA to DROSHA transcript further strengthens the binding of the m^(6)A reader IGF2BP2 to stabilize m^(6)A-modified DROSHA.In addition,wild-type DROSHA,but not an m^(6)A methylation-deficient mutant,enhances BCSC stemness maintenance,while inhibition of DROSHA m^(6)A modification attenuates BCSC traits.Our study unveils the AURKA-induced oncogenic m^(6)A modification as a key regulator of DROSHA in breast cancer and identifies a novel DROSHA transcriptional function in promoting the BCSC phenotype. | Fei Peng Jie Xu Bai Cui Qilan Liang Sai Zeng Bin He Hong Zou Manman Li Huan Zhao Yuting Meng Jin Chen Bing Liu Shasha Lv Peng Chu Fan An Zifeng Wang Junxiu Huang Yajing Zhan Yuwei Liao Jinxin Lu Lingzhi Xu Jin Zhang Zhaolin Su Zhiguang Li Fangjun Wang Eric W-FLam Quentin Liu | 2021 | Cell Research2021，31，3： | 9 |
| 20 | Wheat genomic study for genetic improvement of traits in China显示文摘Bread wheat(Triticum aestivum L.)is a major crop that feeds 40%of the world’s population.Over the past several decades,advances in genomics have led to tremendous achievements in understanding the origin and domestication of wheat,and the genetic basis of agronomically important traits,which promote the breeding of elite varieties.In this review,we focus on progress that has been made in genomic research and genetic improvement of traits such as grain yield,end-use traits,flowering regulation,nutrient use efficiency,and biotic and abiotic stress responses,and various breeding strategies that contributed mainly by Chinese scientists.Functional genomic research in wheat is entering a new era with the availability of multiple reference wheat genome assemblies and the development of cutting-edge technologies such as precise genome editing tools,highthroughput phenotyping platforms,sequencing-based cloning strategies,high-efficiency genetic transformation systems,and speed-breeding facilities.These insights will further extend our understanding of the molecular mechanisms and regulatory networks underlying agronomic traits and facilitate the breeding process,ultimately contributing to more sustainable agriculture in China and throughout the world. | Jun Xiao Bao Liu Yingyin Yao Zifeng Guo Haiyan Jia Lingrang Kong Aimin Zhang Wujun Ma Zhongfu Ni Shengbao Xu Fei Lu Yuannian Jiao Wuyun Yang Xuelei Lin Silong Sun Zefu Lu Lifeng Gao Guangyao Zhao Shuanghe Cao Qian Chen Kunpu Zhang Mengcheng Wang Meng Wang Zhaorong Hu Weilong Guo Guoqiang Li Xin Ma Junming Li Fangpu Han Xiangdong Fu Zhengqiang Ma Daowen Wang Xueyong Zhang Hong-Qing Ling Guangmin Xia Yiping Tong Zhiyong Liu Zhonghu He Jizeng Jia Kang Chong | 2022 | Science China(Life Sciences)2022，65，9： | 9 |
