| 1 | BE-PLUS: a new base editing tool with broadened editing window and enhanced fidelity显示文摘基础编辑() ,包含 cytidine 脱氨基酶和催化地有缺点的 Cas9,广泛地被用来执行基础编辑。然而,狭窄的编辑窗口是限制它的实用程序。这里,我们开发了依照到由熔化 10 的 U (T) 范围(加) 的更大的 C 为招募 GCN4 肽拷贝到 nCas9 (D10A ) 的编程作为基础编辑命名的一种新编辑技术 scFv-APOBEC-UGI-GB1 到目标地点。新系统完成与一扇拓宽的窗户的基础编辑,导致一个增加的指向染色体的范围。有趣地,新系统很产出更少讨厌的 indels 和 non-C-to-T 变换。我们也通过站 codons (iSTOP ) 的正式就职越过整个染色体在基因混乱表明了它的潜在的使用。一起拿,加系统与编辑窗口和提高的忠实增加提供一个新编辑工具。 | Wen Jiang Songjie Feng Shisheng Huang Wenxia Yu Guanglei Li Guang Yang Yajing Liu Yu Zhang Lei Zhang Yu Hou Jia Chen Jieping Chen Xingxu Huang | 2018 | Cell Research2018，28，8： | 20 |
| 2 | Tomato lncRNA23468 functions as a competing endogenous RNA to modulate NBS-LRR genes by decoying miR482b in the tomato-Phytophthora infestans interaction显示文摘Our previous studies indicated that tomato miR482b could negatively regulate the resistance of tomato to Phytophthora infestans and the expression of miR482b was decreased after inoculation with P.infestans.However,the mechanism by which the accumulation of miR482b is suppressed remains unclear.In this study,we wrote a program to identify 89 long noncoding RNA(lncRNA)-originated endogenous target mimics(eTMs)for 46 miRNAs from our RNA-Seq data.Three tomato lncRNAs,lncRNA23468,lncRNA01308 and lncRNA13262,contained conserved eTM sites for miR482b.When lncRNA23468 was overexpressed in tomato,miR482b expression was significantly decreased,and the expression of the target genes,NBS-LRRs,was significantly increased,resulting in enhanced resistance to P.infestans.Silencing lncRNA23468 in tomato led to the increased accumulation of miR482b and decreased accumulation of NBS-LRRs,as well as reduced resistance to P.infestans.In addition,the accumulation of both miR482b and NBS-LRRs was not significantly changed in tomato plants that overexpressed lncRNA23468 with a mutated eTM site.Based on the VIGS system,a target gene of miR482b,Solyc02g036270.2,was silenced.The disease symptoms of the VIGS-Solyc02g036270.2 tomato plants were in accordance with those of tomato plants in which lncRNA23468 was silenced after inoculation with P.infestans.More severe disease symptoms were found in the modified plants than in the control plants.Our results demonstrate that lncRNAs functioning as eTMs may modulate the effects of miRNAs in tomato and provide insight into how the lncRNA23468-miR482b-NBS-LRR module regulates tomato resistance to P.infestans. | Ning Jiang Jun Cui Yunsheng Shi Guanglei Yang Xiaoxu Zhou Xinxin Hou Jun Meng Yushi Luan | 2019 | Horticulture Research2019，6，1： | 12 |
| 3 | Hierarchical composite of biomass derived magnetic carbon framework and phytic acid doped polyanilne with prominent electromagnetic wave absorption capacity显示文摘To solve the electromagnetic pollution,herein,a CoFe_(2)O_(4)/C/PANI composite was developed by a green route,which was constructed with spinel of metal oxide,graphitized carbon and conductive polymer composites.Benefiting from the designable interfaces and increased dipoles,the microwave dielectric response capability can be boosted significantly and resulted in the enhanced microwave absorbing performance.As revealed by the reflection loss curve,the minimum reflection loss(RLmin) reached-51.81 dB at 12.4 GHz under a matched thickness of 2.57 mm.At 2.5 mm,the effective absorbing band covered 8.88 GHz,suggesting the desirable wideband feature.In our case,the method of utilization of a novel green way to fabricate multiple-component EM absorber can be a promising candidate for high-performance EM absorber. | Tianqi Hou Zirui Jia Ailing Feng Zehua Zhou Xuehua Liu Hualiang Lv Guanglei Wu | 2021 | Journal of Materials Science & Technology2021，，9： | 8 |

| 5 | FSIP1 enhances the therapeutic sensitivity to CDK4/6 inhibitors in triple-negative breast cancer patients by activating the Nanog pathway显示文摘CDK4/6 inhibitors are routinely recommended agents for the treatment of advanced HR+HER2-breast cancer.However,their therapeutic effectiveness in triple-negative breast cancer(TNBC)remains controversial.Here,we observed that the expression level of fibrous sheath interacting protein 1(FSIP1)could predict the treatment response of TNBC to CDK4/6 inhibitors.High FSIP1 expression level was related to a poor prognosis in TNBC,which was associated with the ability of FSIP1 to promote tumor cell proliferation.FSIP1 downregulation led to slowed tumor growth and reduced lung metastasis in TNBC.FSIP1knockout caused cell cycle arrest at the G0/G1 phase and reduced treatment sensitivity to CDK4/6 inhibitors by inactivating the Nanog/CCND1/CDK4/6 pathway.FSIP1 could form a complex with Nanog,protecting it from ubiquitination and degradation,which may facilitate the rapid cell cycle transition from G0/G1 to S phase and exhibit enhanced sensitivity to CDK4/6 inhibitors.Our findings suggest that TNBC patients with high FSIP1 expression levels may be suitable candidates for CDK4/6 inhibitor treatment. | Guanglei Chen Lisha Sun Xi Gu Liping Ai Jie Yang Zhan Zhang Pengjie Hou Yining Wang Xunyan Ou Xiaofan Jiang Xinbo Qiao Qingtian Ma Nan Niu Jinqi Xue Hao Zhang Yongliang Yang Caigang Liu | 2023 | Science China(Life Sciences)2023，66，12： | 1 |
| 6 | Evolution characteristics of hydrological connectivity pattern of marsh wetland in Naoli River Basin显示文摘As an important indicator of the structural and functional stability of wetland landscapes,hydrological connectivity plays an important role in maintaining the stability of wetland ecosystems.Large-scale human activities have led to significant changes in the hydrological connectivity pattern of wetlands in Naoli River Basin since 1950 s.Combined with the availability of wetland habitat and the spreading capacity of aquatic birds,hydrological connectivity indices of marsh wetlands were calculated in the studied area,and the temporal and spatial changes were analyzed from 1950 s to 2015.The results indicate that:(1)the hydrological connectivity index of the marsh wetlands shows a growth trend with increasing distance threshold.All patches of marsh wetlands linked together when the distance threshold reached 35--40 km;(2)the optimal distance of hydrological connectivity is about 10 km for marsh wetlands of whole Naoli River Basin;(3)the total hydrological connectivity of marsh wetlands decreased in the Naoli River Basin from 1950 s to 2015.Although the hydrological connectivity index increased after 2005,the fragmentation of the landscape has not been improved.The analysis of the wetland hydrological connectivity can provide a scientific basis for the ecological restoration and protection of the wetland in the Naoli River Basin. | WANG Haonan HOU Guanglei YANG Changbao SONG Xiaolin | 2021 | Global Geology2021，24，2： | 0 |
| 7 | Evaluation and Driving Force Analysis of Cultivated Land Quality in Black Soil Region of Northeast China显示文摘Cultivated land is an important natural resource to ensure food,ecological and economic security.The cultivated land quality evaluation(CQE)is greatly significant for protecting and managing cultivated land.In this study,320 counties in the black soil region of Northeast China(BSRNC)represent the research units used to construct the CQE system measuring the soil properties(SP),cultivated land productivity(CLP),ecological environment(EE)and social economy(SE).The total of 19 factors were selected to calculate the integrated fertility index(IFI)and divided into grades.Simultaneously,we used the coupling coordination degree model to comprehensively analyze the spatial pattern of the cultivated land quality(CLQ)in the BSRNC,and use the structural equation model(SEM)to analyze the driving mechanism.The results show the following:1)The CLQ of 262 counties in the BSRNC is in a state of coupling and coordination,and the coupling and coordination degree presents a spatial distribution pattern of‘high in the southwest and northeast,low in the northwest and southeast’.The coordinated development degree of 271 counties is between 0.4 and 0.6,which is in a transitional state between coordination and disorder.2)The CLQ in the BSRNC is generally good,with an average grade of 3.High-quality cultivated land accounts for 58.45%of all counties,middle-and upper-quality cultivated land accounts for 27.05%,and poor-quality cultivated land accounts for 14.49%.3)The SEM analysis shows that the SP,CLP,EE,and SE all influence the CLQ.Among them,the SP has the largest driving force on the CLQ,while the SE has the smallest driving force on it.The results confirm that the main factors affecting the evaluation results are crop productivity level,normalized difference vegetation index,ratio vegetation index,difference vegetation index,and organic carbon content.When implementing protection measures in counties with a low CLQ,considering a balanced coordination of multiple systems and reasonably controlling the quality degradation are important.This study provides the current situation and driving factors of the CLQ in the BSRNC and will play an important role in black soil governance and utilization. | WANG Mingchang LIU Xingnan LIU Ziwei WANG Fengyan LI Xiaoyan HOU Guanglei ZHAO Shijun | 2023 | Chinese Geographical Science2023，33，4： | 0 |
| 8 | Characteristics of land use conversion in soda saline-alkali soil region of central Northeast China显示文摘Since the 1970s,the soda saline-alkali soil region,which is located in the semiarid-arid region of the central Northeast China,has experienced drastic climate variability.Meanwhile,human activities and socio-economic development have led to an increase in water consumption.These factors have brought out considerable land use change and a lot of soil salinize-alkalization.The land use types were obtained from remote sensing images interpretation based on Landsat MSS in 1970s,TM,ETM in 1990s and 2010s.The characteristics of land use conversion and its response to climate change and influence of human activities were explored in the study area during 1970-2010.The results include:(1)The land use types had changed significantly,especially farmland and grassland,with annual growth rates of 0.31% and 0.35%,respectively.In terms of the saline-alkali land,the area increased greatly during 1970-1990,and its increase was mainly from grassland.There was a decrease from 1990 to 2010,and the loss of saline-alkali was replaced by farmland and grassland.(2)Climate change in the study area is obvious,showing a trend of decreasing precipitation and increasing temperature.The change of saline-alkali land area is closely related to the precipitation,with R2=0.78,passed a passing the 0.01 significance test.(3)The correlation of land use degree index and human activity index with saline-alkali land was not obvious,and the changes in these indices only reflected the land use patterns.Under sufficient rainfall,the saline-alkali land was developed into farmland by humans,which caused the decrease of the saline-alkali land.Therefore,climate change is the main driving force of land salinization in the study area. | ZHANG Haobin YANG Changbao GUO Huali HOU Guanglei | 2022 | Global Geology2022，25，2： | 0 |
