Objective To explore the role of urokinase-type plasminogen activator（uPA） in precontact sperm-egg communication and fertility of mice in vitro. Methods Firstly, sperm chemotaxis （SC） induced by uPA was assayed by measuring the sperm densities in capillaries with a descending gradient or no gradient of uPA respectively. Secondly, the role of uPAR that exists in sperm plasma membrane in SC was studied by examining the change of sperm density in capillary after incubating spermatozoa with anti-uPAR antibody. Thirdly, SC induced by eggs, which had been treated with uPA, PAl-1 and anti-uPAR beforehand respectively, was assayed to study the role of uPA in PSEC. Lastly, the fertilization capability of spermatozoa treated with uPA was examined by counting the number of fertilized eggs. Results 1）The density of spermatozoa that migrated down the gradient of uPA into the capillary was significantly lower than that into the capillary containing no-gradient uPA. 2） When uPAR of spermatozoa was inhibited by anti-uPAR antibody, the density of spermatozoa that migrated into the capillary with ascending gradient of uPA decreased correspondingly. 3） The density of spermatozoa attracted by eggs, which were treated with uPA beforehand, increased significantly than that of attracted by non-treated eggs. On the contrary, the sperm density decreased correspondingly when the egg was treated with PAI-1. 4） The number of fertilized eggs increased significantly after the spermatozoa used here was treated with uPA beforehand. Conclusion uPA could induce SC of mice sperm in vitro through the uPAR on its membrane, enhance the capability of egg inducing SC, and promote spermatozoa to fertilize eggs. Thus, uPA may act as an attractant in PSEC, increase the chance encounter of spermatozoa and eggs, therefore, enhance the fertility success correspondingly. This study, in some degree, provides an evidence that uPA may be used as a new medicine and diagnostic reagent for male infertility.

Gene expression changes of urokinase plasminogen activator and urokinase receptor in rat testes at postnatal stages

引用

Asian Journal of Andrology 2007年第5期9卷 679-683页

作者： Dong-hui huang hu Zhao yong-hong tian hong-gang li xiao-fang ding cheng-liang xiong Family Planning Research Institute Tongji Medical College Huazhong University of Science ＆ Technology Wuhan 43003 China Department of human Anatomy Tongji Medical College Huazhong University of Science ＆ Technology Wuhan 43003 China

Aim： To investigate the gene expression changes of urokinase plasminogen activator （uPA）/urokinase receptor （uPAR） in rat testes at postnatal stages and explore the effects of uPA/uPAR system on the rat spermatogenesis. Methods： The mRNAs of uPA and uPAR in rat testes were measured by using real-time quantitative polymerase chain reaction （PCR） at postnatal days 0, 5, 10, 15, 21, 28, 35, 42, 49 and 56, respectively. Results： The tendencies of uPA and uPAR mRNA expression were similar at most postnatal stages except for Do. The expression of uPAR mRNA in rats testes was relatively higher than that of uPA at postnatal Do, and both were decreased until D21, increased obviously at postnatal D28, reached a peak at postnatal D35, then declined sharply at postnatal D42 and retained at a low level afterwards. Conclusion： The uPA/uPAR system may be strongly linked to spermiation and spermatogenesis via regulating germ cell migration and proliferation, as well as promoting the spermiation and detached residual bodies from the mature spermatids.

目的:探讨鼠巨细胞病毒(MCMV)感染的不同时期MCMV M83基因mRNA在小鼠睾丸中的表达及与睾丸病变程度的相关性。方法:采用地高辛标记的MCMV M83mRNA寡核苷酸探针对接种MCMV后不同时期的小鼠睾丸组织进行原位杂交(ISH)检测。将ISH阳性杂交信号的平均光吸度(A)值表示睾丸的MCMV负荷量,分析MCMV M83mRNA在感染睾丸中的表达及其负荷量与睾丸病变程度的关系。结果:接种病毒后各时期的睾丸组织中均有MCMV M83mRNA表达,ISH阳性杂交信号主要定位在间质细胞胞浆内。感染d9的平均A值最高(实验组组间比较,P<0．001)。感染不同时期的生精上皮及间质细胞呈现不同程度的病理性炎性改变,d6-9最为严重。结论:睾丸MCMV感染时,MCMV M83基因的mRNA水平与睾丸感染病变程度相关;提示:对MCMV M83mRNA动态检测可估计感染组织的预后。

作者： Zhi-Yuan li Laboratory of Optical Physics Institute of PhysicsChinese Academy of SciencesP.O.Box 603Beijing 100190China

The major purpose of this paper is to present a brief overview of the history and the current status of nanophotonics research in China, and to highlight some research results in the past years made by the Chinese nanophotonics communities. I will first briefly introduce the principles of nanophotonics and several of its major disciplines including photonic crystals, plasmonics and metamaterials, and related artificial acoustic structures. Then I will highlight some major progresses made by Chinese research groups in these areas with the selection made merely based on my personal taste. The aim is to let these results better known and appreciated by researchers in the Chinese communities of nanophotonics and related areas, and provide better opportunities of researchers in different areas to have more communications. I also hope that this brief introduction will help to make a better bridge to connect Chinese nanophotonics communities with the broader communities in the world.
