| 1 | AXL 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 | 2021 | Cell Research2021，31，2： | 39 |
| 2 | The Arabidopsis Anaphase-Promoting Complex/Cyclosome Subunit 1 is Critical for Both Female Gametogenesis and Embryogenesis显示文摘Anaphase-promoting complex/cyclosome (APC/C), a multisubunit E3 ligase, plays a critical role in cell cycle control, but the functional characterization of each subunit has not yet been completed. To investigate the function of APC1 in Arabidopsis, we analyzed four mutant alleles of APC1, and found that mutation in APC1 resulted in significantly reduced plant fertility, accumulation of cyclin B, and disrupted auxin distribution in embryos. The three mutant alleles apc1-1, apc1-2 and apc1-3 shared variable defects in female gametogenesis including degradation, abnormal nuclear number, and disrupted polarity of nuclei in the embryo sac as well as in embryogenesis, in which embryos were arrested at multiple stages. All of these defects are similar to those previously identified in apc4. The mutant apc1-4, in which the T-DNA was inserted after the transmembrane domain at the C-terminus, showed much more severe phenotypes; that is, most of the ovules were arrested at the one-nucleate female gametophyte stage (stage FG1). In the apc1 apc4 double mutants, the fertility was further reduced by one-third in apc1-1/+ apc4-1/+, and in some cases no ovules even survived in siliques of apc1-4/+ apc4-1/+. Our data thus suggest that APC1, an essential component of APC/C, plays a synergistic role with APC4 both in female gametogenesis and in embryogenesis. | Yanbing Wang Yingnan Hou Hongya Gu Dingming Kang Zhang-Liang Chen Jingjing Liu Li-Jia Qu | 2013 | Journal of Integrative Plant Biology2013，55，1： | 7 |

| 4 | 600 Mesh Silicon Carbide Corona Protection Varnish with EPOXY/OMMT Nano-composite Adhesive显示文摘A new corona protection varnish was prepared by using epoxy/montmorillonite nanocomposite and pure epoxy resin as adhesives respectively.The adhesive with different amounts of organic montmorillonite(OMMT) was mixed with 1200 mesh silicon carbide(Si C) by different weight ratios.The surface states of the varnishes with various adhesives were observed by powerful optical microscope.Some properties of the varnishes were analyzed during the enduring time under 5kV/cm DC,such as the relation of change in nonlinear coefficient,natural surface resistivity,and surface temperature variation.The results showed that the amounts of OMMT had little effect on the natural surface resistance of the varnish but had important influence on the nonlinear property of the varnish.When the range of the OMMT content was 2wt% to 6wt%,the nonlinear coefficient of all materials with epoxy/OMMT nano-composite adhesive was higher than that with pure epoxy resin adhesive.The surface temperature of the varnish with epoxy/OMMT nanocomposite adhesive was all lower than that with the pure epoxy resin adhesive under high electrical field strength. | 胡春秀 ZHAO Yingnan HOU Haibo ZHANG Xiaohong | 2016 | Journal of Wuhan University of Technology(Materials Science)2016，31，4： | 0 |

| 6 | Massively parallel sequencing of 231 autosomal SNPs with a custom panel:a SNP typing assay developed for human identification with Ion Torrent PGM显示文摘The custom-designed single nucleotide polymorphism(SNP)panel amplified 231 autosomal SNPs in one PCR reaction and subsequently sequenced with massively parallel sequencing(MPS)technology and Ion Torrent personal genome machine(PGM).SNPs were chosen from SNPforID,IISNP,HapMap,dbSNP,and related published literatures.Full concordance was obtained between available MPS calling and Sanger sequencing with 9947A and 9948 controls.Ten SNPs(rs4606077,rs334355,rs430046,rs2920816,rs4530059,rs1478829,rs1498553,rs7141285,rs12714757 and rs2189011)with low coverage or heterozygote imbalance should be optimized or excluded from the panel.Sequence data had sufficiently high coverage and gave reliable SNP calling for the remaining 221 loci with the custom MPS-SNP panel.A default DNA input amount of 10 ng per reaction was recommended by Ampliseq technology but sensitivity testing revealed positive results from as little as 1 ng input DNA.Mixture testing with this panel is possible through analysis of the F MAR(frequency of major allele reads)values at most loci with enough high coverage depth and low level of sequencing noise.These results indicate the potential advantage of the custom MPS-SNP assays and Ion Torrent PGM platform for forensic study. | Suhua Zhang Yingnan Bian Anqi Chen Hancheng Zheng Yuzhen Gao Yiping Hou Chengtao Li | 2017 | Forensic Sciences Research2017，2，1： | 0 |
