| 7 | Development of mouse preimplantation embryos in space显示文摘The development o f life beyond planet Earth is a long-standing quest of the human race,but whether normal mammalian embryonic development can occur in space is still unclear.Here,we show unequivocally that preimplantation mouse embryos can develop in space;but the rate of blastocyst formation and blastocyst quality are compromised.Additionally,the cells in the embryo contain severe DNA damage,while the genome of the blastocysts developed in space is globally hypomethylated with a unique set of differentially methylated regions.The developmental defects,DNA damage and epigenetic abnormalities can be largely mimicked by the treatment with ground-based low-dose radiation.However,the exposure to simulated microgravity alone does not cause major disruptions of embryonic development,indicating that radiation is the main cause for the developmental defects.This work advances the understanding of embryonic development in space and reveals long-term extreme low-dose radiation as a hazardous factor for mammalian reproduction. | Xiaohua Lei Yujing Cao Baohua Ma Yunfang Zhang Lina Ning Jingjing Qian Liwen Zhang Yongcun Qu Tao Zhang Dehong Li Qi Chen Junchao Shi Xudong Zhang Chiyuan Ma Ying Zhang Enkui Duan | 2020 | National Science Review2020，7，9： | 8 |

| 9 | Induction of matrix metalloproteinase-9 and-2 activity in mouse blastocyst by fibronectin-integrin interaction显示文摘Fibronectin, a major extracellular matrix, plays an important role in embryo implantation by mediating embryo adhesion and outgrowth. In this work, mouse blastocysts produced pro-matrix metalloproteinase-9, pro-matrix metalloproteinase-2 and 64 ku matrix metalloproteinase-2 when they were co-cultured with fibronectin. In contrast, mouse blastocysts did not produce these proteinases without fibronectin. Focal adhesion kinase is a fundamental molecule of integrin signaling pathway and its antisense oligodeoxynucleiotide inhibited blastocyst matrix metalloproteinases expression induced by fibronectin. The results indicated that fibronectin triggered matrix metalloproteinase-9 and -2 expression in mouse blastocyst through its integrin receptors and subsequent signaling pathway, which enhanced the synchronization of blastocyst invasiveness and uterine receptivity and ensured the accuracy of events relative to implantation in timing and spatiality. | TIE Guodong CAO Yujing ZHAO Xingxu Duan Enkui | 2000 | Chinese Science Bulletin2000，45，14： | 7 |
| 10 | Expression of vascular endo-thelial growth factor in rat uterus during peri-implantation显示文摘The first distinct mark of rodent implantation is the increased vascular permeability and significant angio-genesis at the sites of blastocyst implantation, but its mechanism is not clearly defined. Vascular endothelial growth factor (VEGF) is the key mediator for angiogenesis during em-bryogenesis and adult span and also serves as a vascular permeability factor. The aim of this study is to explore VEGF regulation mechanism and the possible role that VEGF plays in implantation by studying the VEGF expression and angiogenesis in the rat uterus during estrous cycle, ovarioec-tomized and peri-implantation stages using in situ message RNA hybridization and confocal laser scanning techniques. The results indicated that VEGF was regulated by ovarian steroid hormones. VEGF expression before implantation was localized at luminal epithelium, shifted to stroma as implantation initiated and extensively located at the decidualizing stroma region after implantation.

| 11 | Role of αVβ3 integrin in embryo implantation in the mouse显示文摘Integrin, a heterodimeric adhesive molecule composed of a and (5 subunits, can regulate cell adhesion and trafficking. Recent data have documented that, at the 'implantation window' stage, aVp3 integrin participates in the maternal-fetal interaction and becomes a potential marker of uterine receptivity. Furthermore, it can affect invasiveness of embryo. This work made a further study about its action mechanism. Results of indirect immunofluorescence and laser scanning confocal microscopy showed that αVβ3 integrin was clearly expressed in the mouse blastocyst. Injection of αVβS integrin antiserum into a uterine horn of a pregnant mouse on day 3 markedly decreased the number of embryos implanted (P < 0.001). In a co-culture model, aVp3 integrin antisera at 1 : 100 and 1 : 200 dilutions significantly depressed the attachment and outgrowth reactions of blastocysts on monolayer of uterine epithelial cells. Analysis of correlation manifested that the inhibitory effect of αVβ3 integrin antiserum was | Liquan Cai Yujing Cao Enkui Duan | 2000 | Chinese Science Bulletin2000，45，22： | 6 |
| 12 | Effects of blocking Le^Y oligosaccharide on cell surface to MMPs secreted by blastocysts and epithelial cells in mouse in vitro显示文摘In order to understand the role of Le+Y oligosaccharide antigen (Le+Y) during implantation, the relationship of Le+Y on the cell surface with matrix metalloproteinase (MMPs) secreted by blastocysts and monolayer epithelial cells during implantation in the mouse %in vitro% was studied by monoclonal antibody (mAb) AH-6, directed to Le+Y[Fuc α1-2 Gal β1-4 (Fuc α1-3) GlcNAc-], and gelatin zymography. The results showed that MMPs secretion was reduced after Le+Y on the cell surface of either epithelial cells or trophoblasts was blocked. It indicated that MMPs expression which played an important function during the process of implantation were regulated by Le+Y. Therefore, it was considered that Le+Y could regulate embryos invasion by some mechanism. | Xiaoqi Wang Yu Liu Enkui Duan Guoqing Zeng Zhengmei Zhu | 1998 | Chinese Science Bulletin1998，43，17： | 6 |
| 13 | Expression, distribution and function of the focal adhesion kinase (pp125^(FAK)) during murine ectoplacental cone outgrowth in vitro显示文摘Mouse embryo implantation is a complex process that includes trophoblast cells derived from ectoplacental cone (EPC) adhesion to and migration through the extracellular matrix (ECM) of uterine endometrium and invasion into the decidua. At the time of implantation, fibronectin (FN) is abundant in the decidua and is distributed pericellularly around each individual stromal cell, and its receptor (integrin α-5β-1) expression on trophoblast populations is up-regulated. The focal adhesion kinase, a 125 ku protein tyrosine kinase (pp125 FAK), is tyrosine phosphorylated upon integrin engagement with its ECM ligand, and its tyrosine phosphorylation sites then serve as the binding sites which couple it with cellular proteins that contain Src SH2 or SH3 domains. Through these linkages, pp125 FAK may integrate multiple signals triggered by integrins. The model of EPC culture %in vitro% was used to study the expression, distribution and function of pp125 FAK during EPC outgrowth on FN. Results indicated that, pp125 FAK primarily expressed and distributed in cellular focal adhesions of the front edge of trophoblast outgrowth from EPC, and was localized in the peripheral region of the individual migrating trophblast cell; antibody or antisense oligodeoxynucleotide to pp125 FAK inhibited EPC attachment and outgrowth, as well as trophoblast cells spreading and migration. This experiment demonstrated that pp125 FAK as an integrin-mediated signaling molecule was involved in EPC outgrowth %in vitro%, and played an important role during trophoblast cells interaction with FN. | ZHANG Chunyu 1,2, DUAN Enkui 1*, CAO Yujing+1and ZENG Guoqing+1 1.

| 14 | Effect of fibronectin and leukaemia inhibitory factor on matrix metalloproteinases in mouse blastocyst显示文摘This study was designed to detect the effects of fibronectin (FN) and leukaemia inhibitory factor (LIF) on matrix metallopoteinases (MMPs) of mouse blastocysts. The experiments comprised four groups: first, blastocysts grew on the dishes with FN-coated; the second, without FN-coated; the third group, without FN coated, but with 20 ng/μL LIF added to culture medium; and the fourth group, with both FN-coated and 20 ng/μL LIF added. Using MMP-2 and MMP-9 primers respectively, the expressions of MMP-2 and MMP-9 were detected by RT-PCR and cloning identification. The results showed that in the first group, MMP-2 and MMP-9 were produced after 12 and 24 h culturing; in the third group, there were both MMP-2 and MMP-9 bands when blastocysts were cultured for 24 h; and in the fourth group, MMP-2 and MMP-9 bands appeared when blastocysts were cultured for 6, 12 and 24 h. But in the second group no MMP-2 or MMP-9 band appeared. These results show that FN may initiate the transcription of MMP-2 and MMP-9 genes | Jian Zhang Guodong Tie Yujing Cao Enkui Duan | 2001 | Chinese Science Bulletin2001，46，15： | 4 |
| 15 | mTOR signaling promotes stem cell activation via counterbalancing BMP-mediated suppression during hair regeneration显示文摘Hair follicles(HFs)undergo cycles of degeneration(catagen),rest(telogen),and regeneration(anagen)phases.Anagen begins when the hair follicle stem cells(HFSCs)obtain sufficient activation cues to overcome suppressive signals,mainly the BMP pathway,from their niche cells.Here,we unveil that mTOR complex 1(mTORC1)signaling is activated in HFSCs,which coincides with the HFSC activation at the telogen-to-anagen transition.By using both an inducible conditional gene targeting strategy and a pharmacological inhibition method to ablate or inhibit mTOR signaling in adult skin epithelium before anagen initiation,we demonstrate that HFs that cannot respond to mTOR signaling display significantly delayed HFSC activation and extended telogen.Unexpectedly,BMP signaling activity is dramatically prolonged in mTOR signaling-deficient HFs.Through both gain-and loss-of-function studies in vitro,we show that mTORC1 signaling negatively affects BMP signaling,which serves as a main mechanism whereby mTORC1 signaling facilitates HFSC activation.Indeed,in vivo suppression of BMP by its antagonist Noggin rescues the HFSC activation defect in mTORC1-null skin.Our findings reveal a critical role for mTOR signaling in regulating stem cell activation through counterbalancing BMP-mediated repression during hair regeneration. | Zhili Deng Xiaohua Lei Xudong Zhang Huishan Zhang Shuang Liu Qi Chen Huimin Hu Xinyue Wang Lina Ning Yujing Cao Tongbiao Zhao Jiaxi Zhou Ting Chen Enkui Duan | 2015 | Journal of Molecular Cell Biology2015，7，1： | 3 |
| 16 | The expression and function of VEGF at embryo implantation 'window' in the mouse显示文摘Vascular endothelial growth factor (VEGF) is an endothelial cell-specific mitogen that plays a critical role in angiogenesis. Recent reports indicated that VEGF was closely involved in embryo implantation and embryonic vasculogenesis. However, very little information is available about the detailed expression and function of VEGF at implantation 'window'. In this work, VEGFs were primarily present on uterine epithelial cell monolayer and blasto-cysts including the outgrew trophoblasts at implantation window. VEGF antibodies decreased the number of mice embryos implanted and the percentage of blastocysts with attachment and outgrowth in a co-culture model in a dose-dependant manner. These findings demonstrate that VEGF is one of the essential cytokines for embryo implantation in mouse. VEGF may act as a local mediator to regulate the maternal-fetal interaction, and facilitate blastocyst implantation. | Jing Zhang Li Wang Liquan Cai Yujing Cao Enkui Duan | 2001 | Chinese Science Bulletin2001，46，5： | 2 |
| 17 | Effects of vascular endothelial growth factor on MMPs during embryo implantation in mice显示文摘Vascular endothelial growth factor (VEGF) is a specific mitogen of endothelial cells and plays an important role in vasculogenesis and angiogenesis. In recent years, both our and other laboratories have found that VEGF may be involved in embryo implantation. However, the relationship between VEGF and MMP-2 and MMP-9, the marker molecules of embryo implantation, is still unknown. In the present study, an examination of the effects of VEGF on the expression and secretion of MMP-2 and MMP-9 during implantation in mice was carried out by RT-PCR and gelatin zymography. The results show that VEGF antibody significantly decreased uterine mRNA levels of MMP-2 and MMP-9 during pregnancy, and that VEGF could up-regulate the activities of MMP-2 and MMP-9 secreted by blastocysts cultured in vitro in a time- and dose-dependent manner. The results suggest that, in the course of implantation, the ability for metastasis and invasion of blastocysts and the receptive-ness of the uterus might be regulated by VEGF | LI Sumin CAO Yujing ZHANG Jian TIAN Yongqiang ZHENG Xing DUAN Enkui | 2002 | Chinese Science Bulletin2002，47，24： | 2 |
| 18 | Embryo implantation:A time for recalling and forwarding显示文摘The success of embryo implantation is a critical step towards further embryo development and pregnancy outcome. The observations and investigations on embryo implantation have been over a century. A huge body of knowledge has been accumulated in anatomy, histology, ultrastructure and hormonal regulation; as well as recently in depth information about molecular signaling pathways got from studies of genomic wide gene screening and specific gene deletion. The knowledge from basic research has also substantially helped to initiate and improve the Artificial Reproductive Technology (ART) in clinical applications. Now we've known that the normal embryo implantation involves the embryo's development into an implantation-competent blastocyst and the synchronized transformation of uteri into a receptive stage. The interdependent relationship between the blastocyst and uterus involves complicated hormonal regulation and local paracrine, juxtacrine interactions. In this paper, we review some important historical findings regarding uterine receptivity and blastocyst activation, as well as some less discussed topics such as embryo spacing, embryo orientation. Further understandings on detailed mechanisms during the process of embryo implantation will help cure women infertility as well as develop new generation of non-steroids contraceptives. | CHEN Qi PENG HongYing ZHANG Ying LEI Li CAO YuJing Duan EnKui | 2009 | Chinese Science Bulletin2009，54，22： | 2 |
