| 1 | Discovery of the migrasome, an organelle mediating release of cytoplasmic contents during cell migration显示文摘房间通过 secreting 和释放蛋白质和泡与对方一起交流。许多房间能移居。在这研究,我们报导 migracytosis,为释放细胞的内容的房间迁居依赖者机制,和 migrasomes 的发现,调停的小囊的结构 migracytosis。当移居的房间移动,他们离开长管状的海滨,叫的收回纤维,在他们后面。大泡,包含众多的更小的泡,在收回纤维的尖端和交叉上成长。这些纤维,与主要房间身体连接泡,最后,裂缝,和泡被释放直到细胞外的空间或直接由包围房间收起。因为这些泡的形成是迁居依赖者,我们把他们称为 “ migrasomes”。我们也发现 cytosolic 内容能被搬运进 migrasomes 并且通过 migrasomes 免除了房间。我们把这迁居依赖者版本机制称为 “ migracytosis”。 | Liang Ma Ying Li Junya Peng Danni Wu Xiaoxin Zhao Yitong Cui Lilian Chen Xiaojun Yan Yanan Du Li Yu | 2015 | Cell Research2015,25,1: | 21 |
| 2 | Combined obeticholic acid and apoptosis inhibitor treatment alleviates liver fibrosis显示文摘Obeticholic acid(OCA), the first FXR-targeting drug, has been claimed effective in the therapy of liver fibrosis. However, recent clinical trials indicated that OCA might not be effective against liver fibrosis, possibly due to the lower dosage to reduce the incidence of the side-effect of pruritus. Here we propose a combinatory therapeutic strategy of OCA and apoptosis inhibitor for combating against liver fibrosis. CCl4-injured mice, D-galactosamine/LPS(GalN/LPS)-treated mice and cycloheximide/TNFα(CHX/TNFα)-treated HepG2 cells were employed to assess the effects of OCA, or together with IDN-6556, an apoptosis inhibitor. OCA treatment significantly inhibited hepatic stellate cell(HSC)activation/proliferation and prevented fibrosis. Elevated bile acid(BA) levels and hepatocyte apoptosis triggered the activation and proliferation of HSCs. OCA treatment reduced BA levels but could not inhibit hepatocellular apoptosis. An enhanced anti-fibrotic effect was observed when OCA was co-administrated with IDN-6556. Our study demonstrated that OCA inhibits HSCs activation/proliferation partially by regulating BA homeostasis and thereby inhibiting activation of HSCs. The findings in this study suggest that combined use of apoptosis inhibitor and OCA at lower dosage represents a novel therapeutic strategy for liver fibrosis. | Jiyu Zhou Ningning Huang Yitong Guo Shuang Cui Chaoliang Ge Qingxian He Xiaojie Pan Guangji Wang Hong Wang Haiping Hao | 2019 | Acta Pharmaceutica Sinica B2019,9,3: | 13 |
| 3 | Atg5 regulates late endosome and lysosome biogenesis显示文摘Autophagy is an evolutionarily conserved lysosome-based degradation process.Atg5 plays a very important role in autophagosome formation.Here we show that Atg5 is required for biogenesis of late endosomes and lysosomes in an autophagy-independent manner.In Atg5 cells,but not in other essential autophagy genes defecting cells,recycling and retrieval of late endosomal components from hybrid organelles are impaired,causing persistent hybrid organelles and defective formation of late endosomes and lysosomes.Defective retrieval of late endosomal components from hybrid organelles resulting from impaired recruitment of a component of V1-ATPase to acidic organelles blocks the pH-dependent retrieval of late endosomal components from hybrid organelles.Lowering the intracellular pH restores late endosome/lysosome biogenesis in Atg5 cells.Our data demonstrate an unexpected role of Atg5 and shed new light on late endosome and lysosome biogenesis. | PENG JunYa ZHANG Ran CUI YiTong LIU HaoDong ZHAO XiaoXin HUANG Lei HU MingXu YUAN XiaoXi MA BenYu MA XiaoWei TAKASHI Ueno MASAAKI Komatsu LIANG XingJie YU Li | 2014 | Science China(Life Sciences)2014,57,1: | 6 |
| 4 | Preparation and application of streptavidin magnetic particles显示文摘Two kinds of streptavidin magnetic particles,namely streptavidin GoldMag particles and streptavidin amino terminal particles were prepared by the methods of physical adsorption and covalent interaction respectively.The streptavidin coated on magnetic particle surface,crucial to many applications,was greatly influenced by the choice of the different buffer.Compared with DynalbeadsM-270 streptavidin, the binding capacity for biotin of different streptavidin magnetic particles was determined by enzyme inhibition method,and the coupling capacity and activity of biotinylated oligonucleotide on their sur- face were also analyzed.The results indicated that the streptavidin GoldMag particle prepared by physical adsorption was stable in STE(NaCl-Tris-EDTA)buffer that was frequently used in nucleic acid hybridization and detection.The streptavidin amino terminal particles prepared by covalent interaction could be used both in STE buffer and PBS(phosphate buffered saline)buffer.The biotin binding ca- pacity for 1 mg of streptavidin GoldMag particles and streptavidin amino terminal particles was 4950 and 5115 pmol respectively.The capacity of biotinylated oligonucleotide(24 bp)coupled on 1 mg of GoldMag and amino terminal magnetic particles was 2839 and 2978 pmol separately.These data were about 6-7 times higher than those of DynabeadsM-270 streptavidin.The hybridization results with FITC-labeled complementary probe on magnetic particle surface demonstrated that the oligonucleotide coupled on streptavidin magnetic particles had high biological activity. | ZHANG ZhiFeng ZHU HongLi TANG YiTong CUI Ting GENG TingTing CHEN Chao CUI YaLi | 2007 | Science China Chemistry2007,50,1: | 1 |
| 5 | Cloud-Assisted Distributed Edge Brains for Multi-Cell Joint Beamforming Optimization for 6G显示文摘In 5G networks,optimization of antenna beam weights of base stations has become the key application of AI for network optimization.For 6G,higher frequency bands and much denser cells are expected,and the importance of automatic and accurate beamforming assisted by AI will become more prominent.In existing network,servers are“patched”to network equipment to act as a centralized brain for model training and inference leading to high transmission overhead,large inference latency and potential risks of data security.Decentralized architectures have been proposed to achieve flexible parameter configuration and fast local response,but it is inefficient in collecting and sharing global information among base stations.In this paper,we propose a novel solution based on a collaborative cloud edge architecture for multi-cell joint beamforming optimization.We analyze the performance and costs of the proposed solution with two other architectural solutions by simulation.Compared with the centralized solution,our solution improves prediction accuracy by 24.66%,and reduces storage cost by 83.82%.Compared with the decentralized solution,our solution improves prediction accuracy by 68.26%,and improves coverage performance by 0.4 dB.At last,the future research work is prospected. | Juan Deng Kaicong Tian Qingbi Zheng Jielin Bai Kuo Cui Yitong Liu Guangyi Liu | 2022 | China Communications2022,19,3: | 0 |
| 6 | Interplay between the atomic structures and superconductivity of two-monolayer Pb films显示文摘Superconductors with reduced dimensionality have been widely explored for their exotic superconducting behaviors.Especially,at the two-dimensional limit,two-monolayer Pb films with two types of structures provide an ideal platform to unveil the underlying superconducting mechanism[Science 324,1314(2009)].Here,by combining scanning tunneling microscopy(STM)with the first-principle calculations,we successfully identify that these two types have different atomic lattice structures with varying stacking phases,which further enables us to calculate the phonon spectrum and electron phonon coupling strength of each type.The theoretical calculations are in good agreement with tunneling spectroscopy measurements of the superconducting transition temperatures(T_(c)),which established a correlation between atomic structures and superconductivity.Moreover,it was observed that the higher T_(c)of these two types also possess higher out-of-plane upper critical magnetic fields(Hc2).These findings will provide important new insights into two-dimensional superconductivity at the atomic level. | Kun Xie Ze Huang Pengju Li Yumin Xia Desheng Cai Yitong Gu Yuzhou Liu Fangliang Cai Runxiao Zhang Haohao Shi Ping Cui Shengyong Qin | 2024 | Science China(Physics,Mechanics & Astronomy)2024,67,1: | 0 |
| 7 | Water-in-Water Emulsions,Ultralow Interfacial Tension,and Biolubrication显示文摘A water-in-water(W/W)emulsion consists of droplets formed by the spontaneous liquid-liquid separation of two immiscible aqueous phases.The inherent properties of the W/W interfaces,low or ultralowinterfacial tension(γ_(W/W)=1-1000μN/m)and a large thickness of several nanometers,beget the poor inherent stability of emulsions.Herein,we report a nanofibril emulsifier having Schiff base reactivity to generate a W/W emulsion.The W/W emulsion has superior stability(stable>6 months)because collagen nanofibrils,acting as a stabilizer of W/W emulsions,can simultaneously satisfy the requirements of sizeandoverall coverage ratio of the phase interfaces.W/Wemulsions having γ_(W/W)∼10μN/m were used as synthetic synovial fluids,showing superior lubrication performance with a coefficient of friction in the range of 0.003-0.011,which has been demonstrated to be suitable for joint lubrication.An intraarticular injection assessment further confirmed this protective effect on articular cartilage in vivo.Our study reveals the mechanism of emulsion stabilization and opens up the possibility of osteoarthritis(OA)treatment using the biolubrication effects of W/W emulsions for lubricated artificial implant surfaces. | Yitong Wang Jin Yuan Yunpeng Zhao Ling Wang Luxuan Guo Lei Feng Jiwei Cui Shuli Dong Shanhong Wan Weimin Liu Heinz Hoffmann Kiet Tieu Jingcheng Hao | 2022 | CCS Chemistry2022,4,6: | 0 |
