| 1 | SARS-CoV-2 envelope protein causes acute respiratory distress syndrome (ARDS)-like pathological damages and constitutes an antiviral target显示文摘Cytokine storm and multi-organ failure are the main causes of SARS-CoV-2-related death.However,the origin of excessive damages caused by SARS-CoV-2 remains largely unknown.Here we show that the SARS-CoV-2 envelope(2-E)protein alone is able to cause acute respiratory distress syndrome(ARDS)-like damages in vitro and in vivo. | Bingqing Xia Xurui Shen Yang He Xiaoyan Pan Feng-Liang Liu Yi Wang Feipu Yang Sui Fang Yan Wu Zilei Duan Xiaoli Zuo Zhuqing Xie Xiangrui Jiang Ling Xu Hao Chi Shuangqu Li Qian Meng Hu Zhou Yubo Zhou Xi Cheng Xiaoming Xin Lin Jin Hai-Lin Zhang Dan-Dan Yu Ming-Hua Li Xiao-Li Feng Jiekai Chen Hualiang Jiang Gengfu Xiao Yong-Tang Zheng Lei-Ke Zhang Jingshan Shen Jia Li Zhaobing Gao | 2021 | Cell Research2021，31，8： | 7 |
| 2 | Antimicrobial peptide LL-37 forms complex with bacterial DNA to facilitate blood translocation of bacterial DNA and aggravate ulcerative colitis显示文摘Bacterial DNA(bacDNA) is frequently found in serum of patient with ulcerative colitis(UC) and Crohn's disease, even blood bacterial culture is negative. How bacDNA evades immune elimination and is translocated into blood remain unclear. Here, we showed that bacDNA avoids elimination and disables bacteriakilling function of antimicrobial peptide LL-37(Cramp in mice) by forming complex with LL-37, which is inducible after culture with bacteria or bacterial products. Elevated LL-37-bacDNA complex was found in plasma and lesions of patients with UC. LL-37-bacDNA promoted inflammation by inducing Th1, Th2 and Th17 differentiation and activating toll-like receptor-9(TLR9). The complex also increased paracellular permeability, which possibly combines its inflammatory effects to promote local damage and bacDNA translocation into blood. Cramp-bacDNA aggravated mouse colitis severity while interference with the complex ameliorated the disease. The study identifies that inflammatogenic bacDNA utilizes LL-37 as a vehicle for blood translocation and to evade immune elimination. Additionally, bacteria may make a milieu by releasing bacDNA to utilize and resist host antimicrobial peptides as a ‘trojan horse'. | Zilei Duan Yaqun Fang Yang Sun Ning Luan Xue Chen Mengrou Chen Yajun Han Yizhu Yin James Mwangi Junkun Niu Kunhua Wang Yinglei Miao Zhiye Zhang Ren Lai | 2018 | Science Bulletin2018，63，20： | 4 |
| 3 | Rapid generation of ACE2 humanized inbred mouse model for COVID-19 with tetraploid complementation显示文摘Although monkeys and pigs can be infected with SARS-Co V-2,they generally have a long growth cycle and a large size that is difficult to handle in large quantities.However,the readily available rats and mice are not susceptible to SARSCo V-2 because of differences in ACE2(angiotensin-converting enzyme 2),the receptor mediating cell entry of SARSCo V-2[1].Thus,the key to establishing a mouse model of COVID-19 is to make the mice express human ACE2 protein,and therefore become SARS-Co V-2 susceptible.Recently reported COVID-19 mouse models using a random insertion transgene approach[2,3]or adenoviral approach to express h ACE2[4],lack the tissue-specificity of h ACE2 expression and might not replicate COVID-19 precisely,limiting their applications in certain studies. | Feng-Liang Liu Kaixin Wu Jiaoyang Sun Zilei Duan Xiongzhi Quan Junqi Kuang Shilong Chu Wei Pang Han Gao Ling Xu Ying-Chang Li Hai-Lin Zhang Xue-Hui ang Rong-Hua Luo Xiao-Li Feng Hans RScholer Xinwen Chen Duanqing Pei Guangming Wu Yong-Tang Zheng Jiekai Chen | 2021 | National Science Review2021，8，2： | 3 |
| 4 | Development of a CLDN18.2-targeting immuno-PET probe for non-invasive imaging in gastrointestinal tumors显示文摘Claudin18.2(CLDN18.2)is a tight junction protein that is overexpressed in a variety of solid tumors such as gastrointestinal cancer and oesophageal cancer.It has been identified as a promising target and a potential biomarker to diagnose tumor,evaluate efficacy,and determine patient prognosis.TST001 is a recombinant humanized CLDN18.2 antibody that selectively binds to the extracellular loop of human Claudin18.2.In this study,we constructed a solid target radionuclide zirconium-^(89)(^(89)Zr)labled-TST001 to detect the expression of in the human stomach cancer BGC823CLDN18.2 cell lines.The[^(89)Zr]Zr-desferrioxamine(DFO)-TST001 showed high radiochemical purity(RCP,>99%)and specific activity(24.15±1.34 GBq/mmol),and was stable in 5%human serum albumin,and phosphate buffer saline(>85%RCP at 96 h).The EC_(50) values of TST001 and DFO-TST001 were as high as 0.413±0.055 and 0.361±0.058 nM(P>0.05),respectively.The radiotracer had a significantly higher average standard uptake values in CLDN18.2-positive tumors than in CLDN18.2-negative tumors(1.11±0.02 vs.0.49±0.03,P=0.0016)2 days post injection(p.i.).BGC823CLDN18.2 mice models showed high tumor/muscle ratios 96 h p.i.with[^(89)Zr]Zr-DFO-TST001 was much higher than those of the other imaging groups.Immunohistochemistry results showed that BGC823CLDN18.2 tumors were highly positive(+++)for CLDN18.2,while those in the BGC823 group did not express CLDN18.2().The results of ex vivo biodistribution studies showed that there was a higher distribution in the BGC823CLDN18.2 tumor bearing mice(2.05±0.16%ID/g)than BGC823 mice(0.69±0.02%ID/g)and blocking group(0.72±0.02%ID/g).A dosimetry estimation study showed that the effective dose of[^(89)Zr]Zr-DFO-TST001 was 0.0705 mSv/MBq,which is within the range of acceptable doses for nuclear medicine research.Taken together,these results suggest that Good Manufacturing Practices produced by this immuno-positron emission tomography probe can detect CLDN18.2-overexpressing tumors. | Yan Chen Xingguo Hou Dapeng Li Jin Ding Jiayue Liu Zilei Wang Fei Teng Hongjun Li Fan Zhang Yi Gu Steven Yu Xueming Qian Zhi Yang Hua Zhu | 2023 | Journal of Pharmaceutical Analysis2023，13，4： | 2 |

| 8 | Turning gray selenium into a nanoaccelerator of tissue regeneration by PEG modification显示文摘Selenium(Se)is an essential trace element involved in nearly all human physiological processes but suffers from a narrow margin between benefit and toxicity.The nanoform of selenium has been proven shown to be more bioavailable and less toxic,yet significant challenges remain regarding the efficient and feasible synthesis of biologically active nanoselenium.In addition,although nanoselenium has shown a variety of biological activities,more interesting nanoselenium features are expected.In this work,hydrosoluble nanoselenium termed Nano-Se in the zero oxidation state was synthesized between gray Se and PEG.A zebrafish screen was carried out in zebrafish larvae cocultured with Nano-Se.Excitingly,Nano-Se promoted the action of the FGFR,Wnt,and VEGF signaling pathways,which play crucial roles in tissue regeneration.As expected,Nano-Se not only achieved the regeneration of zebrafish tail fins and mouse skin but also promoted the repair of skin in diabetic mice while maintaining a profitable safe profile.In brief,the Nano-Se reported here provided an efficient and feasible method for bioactive nanoselenium synthesis and not only expanded the application of nanoselenium to regenerative medicine but also likely reinvigorated efforts for discovering more peculiarunique biofunctions of nanoselenium in a great variety of human diseases. | Jieqiong Cao Yibo Zhang Peiguang Zhang Zilei Zhang Bihui Zhang Yanxian Feng Zhixin Li Yiqi Yang Qilin Meng Liu He Yulin Cai Zhenyu Wang Jie Li Xue Chen Hongwei Liu An Hong Wenjie Zheng Xiaojia Chen | 2022 | Bioactive Materials2022，7，9： | 0 |
| 9 | Warming‑induced changes of broccoli head to cauliflower‑like curd in Brassica oleracea are regulated by DNA methylation as revealed by methylome and transcriptome co‑profiling显示文摘Increasingly warming temperature impacts on all aspects of growth and development in plants.Flower development is a complex process that is very sensitive to ambient temperature,and warming temperatures often lead to abnor-mal flower development and remarkably reduce the quality and yield of inflorescent vegetables and many other crops,which can be exemplified by Brassica oleracea cv.Green Harmony F1,a broccoli cultivar,whose floral develop-ment is ceased at inflorescence meristem(at 28℃)or floral primordium stage(at 22℃),forming a cauliflower-like curd(28℃)or intermediate curd(22℃)instead of normal broccoli head at 16℃.However,the underlying molecular regulatory mechanisms are not well understood.Here we report that warming temperature(28℃ or 22℃)induced hypermethylation of the genome,especially the promoter regions of such sets of genes as ribosome biogenesis-related and others,leading to the suppression of the apex-highly-expressed distinctive genes,subsequently resulting in the abnormal floral development,as revealed by methylome and transcriptome co-profiling.The regulation of warming-induced abnormal floral development in broccoli was further verified by the fact that the DNA methylation inhibitor 5-azacytidine(5-azaC)released the expression of genes from the warming temperature-induced suppres-sion,and restored the broccoli development to normalcy at warming temperature.The research provided new approaches to breeding broccoli and other crops for growing in wider or warmer temperature zones. | Zilei Yao Lu Yuan Ke Liu Tingjin Wang Bin Liu Yan Zhao Susheng Gan Liping Chen | 2022 | Molecular Horticulture2022，2，1： | 0 |
