1AXL is a candidate receptor for SARS-CoV-2 that promotes infection of pulmonary and bronchial epithelial cells显示文摘The current coronavirus disease 2019(COVID-19)pandemic presents a global public health challenge.The viral pathogen responsible,severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),binds to the host receptor ACE2 through its spike(S)glycoprotein,which mediates membrane fusion and viral entry.Although the role of ACE2 as a receptor for SARS-CoV-2 is clear,studies have shown that ACE2 expression is extremely low in various human tissues,especially in the respiratory tract.Thus,other host receptors and/or co-receptors that promote the entry of SARS-CoV-2 into cells of the respiratory system may exist.In this study,we found that the tyrosine-protein kinase receptor UFO(AXL)specifically interacts with the N-terminal domain of SARS-CoV-2 S.Using both a SARS-CoV-2 virus pseudotype and authentic SARS-CoV-2,we found that overexpression of AXL in HEK293T cells promotes SARS-CoV-2 entry as efficiently as overexpression of ACE2,while knocking out AXL significantly reduces SARS-CoV-2 infection in HI 299 pulmonary cells and in human primary lung epithelial cells.Soluble human recombinant AXL blocks SARS-CoV-2 infection in cells expressing high levels of AXL.The AXL expression level is well correlated with SARS-CoV-2 S level in bronchoalveolar lavage fluid cells from COVID-19 patients.Taken together,our findings suggest that AXL is a novel candidate receptor for SARS-CoV-2 which may play an important role in promoting viral infection of the human respiratory system and indicate that it is a potential target for future clinical intervention strategies.Shuai Wang Zongyang Qiu Yingnan Hou Xiya Deng Wei Xu Tingting Zheng Peihan Wu Shaofang Xie Weixiang Bian Chong Zhang Zewei Sun Kunpeng Liu Chao Shan Aifu Lin Shibo Jiang Youhua Xie Qiang Zhou Lu Lu Jing Huang Xu Li 2021Cell Research2021,31,2:39
2Introduction of antisense waxy gene into main parent lines of indica hybrid rice显示文摘Amylose content in rice endosperm is one of the key determinants of rice eating and cooking quality, and the poor quality of indica hybrid rice is closely related to the high amylose level in rice grains. In order to improve the grain quality of the indica hybrid rice by genetic engineering, an antisense fragment of rice waxy gene, driven by the 5’-franking sequences of the rice waxy gene, was successfully introduced into three major parent lines of indica hybrid rice, all contain a high amylose level in the grains, via Agrobacte-rium, and more than 100 hygromycin-resistant plants were regenerated. The analysis of PCR amplification and Southern blots indicated that the T-DNA containing the antisense waxy gene had been integrated into the genome of transgenic rice plants. Most of the primary transgenic rice plants grew normally, and the mature seeds from these transgenic plants were performed for analysis of the amylose content. The results showed that the amylose content in the endosperm of some grainsCHEN Xiuhua LIU Qiaoquan WANG Zongyang WANG Xingwen CAI Xiuling ZHANG Jingliu GU Minghong 2002Chinese Science Bulletin2002,47,14:5

4Design, optimization, and measurement of closed-loop Hall effect current sensor显示文摘A kind of closed-loop Hall effect sensor is designed and fabricated by considering several factors such as iron core material,Hall device,as well as selected integrated circuit.Through studying the effect of the iron material and structures of current sensor,a kind of optimal Hall effect current sensor is found.The experimental results show that the presented closed-loop Hall effect current sensor achieves 1 mA/A sensitivity.And its linearity and accuracy are 0.1%and 0.35%FS,respectively,at currents ranging from 0 to 50 A.CHENG XingGuo LI FuAn ZHANG ZongYang LIU Sheng 2014Science China(Technological Sciences)2014,57,9:3
5Multiple sgRNAs facilitate base editingmediated i-stop to induce complete and precise gene disruption显示文摘Dear Editor,Gene editing is a process to introduce desired changes into targeted loci of genomic DNA.Recently,type II clustered regularly in terspaced short palindromic repeats-associated Cas9 endonuclease(CRISPR/Cas9)system has been demonstrated as a versatile tool for engineering eukaryote genome(Hsu et al.,2014),such as in mice(Zuo et al.,2017).Kun Jia Zongyang Lu Fei Zhou Zhiqi Xiong Rui Zhang Zhiwei Liu Yu'e Ma Lei He Cong Li Zhen Zhu Dejing Pan Zhengxing Lian 2019Protein & Cell2019,10,11:3
6Generation of isogenic single and multiplex gene knockout mice by base editing-induced STOP显示文摘Although CRISPR/Cas9 has been widely used to generate knockout mice, two major limitations remain:the founders usually carry a mixture of genotypes, and mosaicism harboring multiple genotypes.Therefore, it takes a long time to get homozygous mutants. Recently developed base editing(BE) system,which introduces C-to-T conversion without double strand DNA cleavage, has been used to introduce artificial stop codons(i-STOP) to prematurely terminate translation, providing a cleaner strategy for genome engineering. Using this strategy, we generated CD160 KO and VISTA/CD160 double KO mice by microinjection of a single sg RNA targeting CD160 and a mixture of sg RNAs targeting VISTA and CD160,respectively. The BE system induced STOP efficiently in mouse embryos and consequently in founder mice without detectable off-target. Most interestingly, the majority of the mutants harbor same genetic modifications, indicating we generated isogenic single and multiplex gene mutant mice by BE-induced STOP. We also obtained homozygous mutant mouse in F1 mice, demonstrating the accelerated strategy in generating animal models.Guang Yang Tianyu Zhu Zongyang Lu Guanglei Li Hao Zhang Songjie Feng Yajing Liu Jianan Li Yu Zhang Jia Chen Xuejiang Guo Xingxu Huang 2018Science Bulletin2018,63,17:2
7Paleomagnetism and paleoclimate change in the South China Sea since the late Pleistocene显示文摘Signal processing techniques of cross-correlation, power spectral analysis and cross-power spectral analysis are used to determine the relationships between paleomagnetic properties and the oxygen isotope record of the South China Sea during the late Pleistocene. On the basis of correlation tests between the δ18O time series of cores V3 and A15 with the paleomagnetic properties of core SCS01, five events of susceptibility and intensity of natural remanent magnetization are identified as glacial events corresponding to δ18O positive events. The magnetic properties of the sediments which are independent of the geomagnetic field are sensitive climatic indicators which have frequencies corresponding to the Milankovitch orbital parameters.Xidong Chen, Douglas F.

8Molecular marker for screening rice cultivars with intermediate amylose content in indica显示文摘The waxy(Wx)gene of rice encodes the granule-bound starch synthase(GBSS),which was required in the synthesis of amylose in endosperm.Theamylose content(AC)of rice endosperm played an important role in grain yield,palatability,and processing quality.Our previous researehes showed that en-dosperm AC and GBSS contents were correlated with the ability of excising intron1 from the leader sequence of the Wx transcript.Cultivars with highCAI Xiuling~(1)) LIU Qiaoquan~(2)) TANG Shuzhu~(2)) GU Minghong~(2)) WANG Zongyang~(1)) 1)Shanghai Inst of Plant Physiology,the Chinese Academy of Sciences,Shanghai 200032 2)College of Bioscienee and Biotechnology,Yangzhou Univ,Yangzhou 225009,China 2002Chinese Rice Research Newsletter2002,10,3:1
9Allele-specific genome editing of imprinting genes by preferentially targeting non-methylated loci using Staphylococcus aureus Cas9(SaCas9)显示文摘Allele-specific DNA methylation is the most important imprinting marker localized to differentially methylated regions(DMRs),and aberrant genomic imprinted DNA methylation is associated with some human diseases,including Prader-Willi syndrome and cancer.Thus,the development of an effective strategy for the precise editing of allele-specific methylated genes is essential for the functional clarification of imprinting elements and the correction of imprinting disorders in human diseases.To discover a feasible allele-specific genome editing tool based on the CRISPR/Cas system,which is an efficient genetargeting technique in various organisms,we examined the targeting efficiency of Staphylococcus aureus Cas9(SaCas9)and Streptococcus pyogenes Cas9(SpCas9)in response to DNA methylation interference.We found that the targeting efficiency of SaCas9,but not SpCas9,was enhanced by targeted DNA demethylation using the d Cas9-Tet1 catalytic domain(CD)but suppressed by targeted DNA methylation using Dnmt3l-Dnmt3a-d Cas9.An in vitro cleavage assay further demonstrated that SaCas9 nuclease activity was inhibited by 5-methylcytosine(5mC)in a synthesized Cp G-containing context.Further analysis with Ch IP-Q-PCR demonstrated that the non-methylated sequence targeting of Sa Cas9 depends on the binding preference of SaCas9 to non-methylated sequences.Taking advantage of this feature of SaCas9,we have successfully obtained non-methylated allele-biased targeted embryos/mice for two imprinting genes,H19 and Snrpn,with relatively high efficiencies of 28.6%and 47.4%,respectively.These results indicate that the targeting efficiency of SaCas9 was strongly reduced by DNA methylation.By using SaCas9,we successfully achieved allele-specific genome editing of imprinting genes by preferentially targeting non-methylated loci.Yajing Liu Jianan Li Changyang Zhou Bin Meng Yu Wei Guang Yang Zongyang Lu Qingmei Shen Yu Zhang Hui Yang Yunbo Qiao 2019Science Bulletin2019,64,21:1

11The distribution and availability of phosphorus fractions in restored cut slopes soil aggregates:a case study of subalpine road,Southwest China显示文摘The distribution and availability of phosphorus(P)fractions in restored cut slope soil aggregates,along altitude gradients,were analyzed.Samples were collected at 3009,3347,3654 and 3980 m of altitude.We examined soil aggregates total phosphorus(TP),available phosphorus(AP)and phosphorus activation coefficient(PAC),and discovered that there was no significant difference in TP levels between all four altitudes samples(p>0.05).However,there was a significant difference in AP at 3009,3347 and 3980 m of altitude(p<0.05).At the altitudes of 3009,3347 and 3654 m,the AP accumulation in small size aggregates was more advantageous.Overall,PAC dropped steadily as soil aggregates sizes increased,as shown:PAC(3654 m)>PAC(3347 m)>PAC(3009 m)>PAC(3980 m).In all particle size soil aggregates,the distribution of the P fractions was as follows:total inorganic phosphorus(TPi)>total organic phosphorus(TPo)>residual phosphorus(R-P),at 3009,3347 and 3654 m,but a different registry was observed at 3980 m of altitude:TPo>TPi>R-P.Through correlation and multiple stepwise regression analysis,it was concluded that active NaHCO_(3)-Pi was the main AP source.It was also suggested that more attention should be given to the ratio of small particle size aggregates to increase soil AP storage.In order to improve the activation capacity and supply of soil P,along with promotion of the healthy development of soil ecosystem on slope land,it was suggest that inorganic P fertilizer and P activator could be added to soil at both low(3009 m)and high altitudes(3980 m).Mengke Zhu Bocong Huang Shenghao Ai Zongyang Liu Xiaoyan Ai Meihua Sheng Yingwei Ai 2023Frontiers of Environmental Science & Engineering2023,17,4:1

16Cynomolgus-rhesus hybrid macaques serve as a platform for imprinting studies显示文摘Genomic imprinting can lead to allele-specific expression(ASE),where one allele is preferentially expressed more than the other.Perturbations in genomic imprinting or ASE genes have been widely observed across various neurological disorders,notably autism spectrum disorder(ASD).In this study,we crossed rhesus cynomolgus monkeys to produce hybrid monkeys and established a framework to evaluate their allele-specific gene expression patterns using the parental genomes as a reference.Our proof-of-concept analysis of the hybrid monkeys identified 353 genes with allele-biased expression in the brain,enabling us to determine the chromosomal locations of ASE clusters.Importantly,we confirmed a significant enrichment of ASE genes associated with neuropsychiatric disorders,including ASD,highlighting the potential of hybrid monkey models in advancing our understanding of genomic imprinting.Zongyang Lu Jie Li Yong Lu Ling Li Wei Wang Chenchen Zhang Libing Xu Yanhong Nie Changshan Gao Xinyan Bian Zhen Liu Guang-Zhong Wang Qiang Sun 2023The Innovation2023,4,3:0
17Novel evolutionary insights into nemacheilid cavefi sh: evidence from comparative analysis of mitochondrial genomes显示文摘Cavefi sh can be important models for understanding the relationships among evolution,adaptation,and development in extreme environments.However,cavefi sh remain poorly studied,particularly at the genome level.Here,we sequenced the complete mitogenome of three cavefi sh in the family Nemacheilidae(Paranemachilus pingguoensis,Oreonectes polystigmus,and Heminoemacheilus longibarbatus),which were collected from karst caves in South China.The mitogenomes each contained 37 genes(13 protein coding,22 tRNA,and two rRNA genes)and a single control region,with the same genetic arrangement and distribution as those found in vertebrates.The non-synonymous/synonymous mutation ratios(Ka/Ks)of the mitogenomes indicated that the protein-coding genes(PCGs)of the three cavefi sh evolved under purifying selection.The mitogenomes of the three cavefi sh exhibit nucleotide composition biases for PCGs,tRNAs,rRNAs,and the whole genome,indicating that the mitochondrial DNA might have been subjected to evolutionary selection in response to extreme cave environments.Divergence time and evolutionary history analyses suggested that the speciation and diversifi cation of the cavefi sh coincided with the Miocene uplift of the southern Qinghai-Tibet Plateau,which greatly changed cave habitats.Overall,our study sheds light on the mitogenomes,phylogeny,and evolutionary history of nemacheilid cavefi sh.Lei ZHOU Shihui HUANG Qing WANG Zhenhai LI Zongyang LI Anyou HE Jiehu CHEN Li LIU Keshu ZOU 2022Journal of Oceanology and Limnology2022,40,4:0
18Revocable Hierarchical Identity-Based Broadcast Encryption显示文摘Hierarchical Identity-Based Broadcast Encryption(HIBBE) organizes users into a tree-like structure, and it allows users to delegate their decryption ability to subordinates and enable encryption to any subset of users while only intended users can decrypt. However, current HIBBE schemes do not support efficient revocation of private keys. Here, a new primitive called Revocable Hierarchical Identity-Based Broadcast Encryption(RHIBBE) is formalized that allows revocation of the HIBBE. Ciphertext indistinguishability is defined against the selectively Bounded Revocable Identity-Vector-Set and Chosen-Plaintext Attack(IND-s BRIVS-CPA). An IND-s BRIVS-CPA secure RHIBBE scheme is constructed with efficient revocation on prime-order bilinear groups. The unbounded version of the scheme is also shown to be secure but a little weaker than the former under the decisional n-Weak Bilinear Diffie-Hellman inversion assumption.Dawei Li Jianwei Liu Zongyang Zhang Qianhong Wu Weiran Liu 2018Tsinghua Science and Technology2018,23,5:0

20Molecular basis and homeostatic regulation of Zinc taste显示文摘Dear Editor,Among all the essential trace metals,zinc is of particular importance for its huge panoply of biological functions.As a pivotal element for hundreds of enzymes,either scarcity or accumulation of body zinc can lead to severe disorders(Maret,2017).Therefore,body zinc must be tightly regulated in order to keep a precise amount that is sufficient for cells’survival but does not cause toxicity.As diet is the major source of trace elements including zinc,animals must adjust their feeding amount and preference to avoid scarcity or accumulation.However,how animal utilize their gustatory organs to detect zinc in food and whether the taste is regulated with body zinc level are unknown.Metals often cause the sense of taste termed as metallic taste.While sodium of certain concentration range delivers hedonic salty taste,salt solutions of most metals taste aversive.It was reported that zinc,copper and other heavy metal ions trigger an unpleasant sense of astringent/drying,sour or bitter.Although taste receptor cells were found essential for the detection of some divalent ions,the molecular mechanisms for this detection are largely elusive.Recently,the receptors for calcium were unambiguously identified in fruit fly(Lee et al.,2018).However,a full repertoire of receptors for sensing divalent ions is still lacking.Rui Luo Yuxiang Zhang Yinjun Jia Yan Zhang Zongyang Li Jieqing Zhao Ting Liu Wei Zhang 2022Protein & Cell2022,13,6:0
