The research adopts that hu - - ifn gene were introduced into the nuclei of oocytes or cytoplasm of grass carp to develop anti - disease transgenic grass carp breeding researches , combing the adva ntag e of hu - - ifn gene and breeding by genetic engineering , with an aim of finding out an effective way of solving antivirus of hemorrhagic virus of carp completely . in research of transgenic fish , hu - - ifn gene ( recombination gene ) is cutdown and introduced into the nuclei of oocytes or cytoplasm of grass carp at one - cell or two - cell stage via micyoinjection by narashige micyoinjection apparatus 本研究的目的在于以人的-干扰素基因( ifn - )作为目的基因,与鲤鱼-肌动蛋白基因启动子在体外重组,利用原核显微注射转基因技术将人-干扰素基因导入草鱼基因组而开展的抗病转基因草鱼育种研究,其结合了干扰素和基因工程育种抗草鱼出血病病毒的优点,以期获得对草鱼出血病具有天然抗性的转基因鱼,并在此基础上培育出草鱼抗病新品系。
The mouse fertilized egg is the most simple and natural mammalian model of cell cycle , there are few reports about the mechanism on the regulation of early development of mouse fertilized eggs especially the events of entry into m - phase . its the first time we report here that pkb exists and effects on g2 / m phase transition in mouse one - cell stage fertilized eggs 148 - 411是激酶区(催化域) ,和其它丝苏氨酸蛋白激酶有较高的同源性,其中有一个保守的thr ,它位于308 、 309或305位;从412位起为c末端尾区(调节域) ,除pkb -外都有一个保守的ser ,位于473或474位。
The stage when the block occurs has been correlated to the time the embryonic genome takes over control of development from the maternal genome , which occurs in mouse at the 2 - cell stage . the embryos of balb / cxicr fl mouse show 2 - cell block in vitro and the effects of several culture media on overcoming the 2 - cell block in embryos development were studied . m16 ( sigma ) , in which 96 . 2 % of 1 - cell embryos developed to 4 - cell stage , were shown to be effective in overcoming the 2 - cell block 培养5h后, 53去核卵母细胞可见标记的mtocs ,但数量明显少于对照组,而又多于培养0h的去核细胞,说明此时53的化学去核卵胞质中确有mtocs的存在,其微管聚合能力正在恢复; mtocs标记,但其辐射产生的微管纤维短,结构还不够丰满;其余细胞的微管蛋白则丧失重新装配能力。
We also stained the embryos with anti - arp3 antibody and found that these two kinds of antigen are generally co - localized but arp3 were not detected in cleavage stage embryos . it was deduced that cortactin functions in the cytokinesis independent of arp3 . and microinjection of anti - cortactin antibodies into the i cell stage embryos leaded to fatal developmental defects because of the unequal cytokinesis 在利用抗ap3的抗体进行的胚胎整装染色中,激光扫描共聚焦显微镜观察发现, arp3在卵裂期没有表达, mbt后,在细胞皮层区检测到arp3蛋白的阳性染色,在随后的发育过程中arp3与皮层蛋白共分布。
In this article , we microinjected camp ( as activator of pka ) and protein kinase inhibitor ( pki ) ( as inhibitor of pka ) into mouse 1 - cell stage fertilized eggs , the camp concentration , pka and mpf activaty were detected , also the cdc25c , cdc2 phosphorylated state and the concentration of ptyr15 for cdc2 , cyclin b1 . materials females of 4 - 5 week - old kuming mice and males of 8 week - old kuming mice were supplied from the department of laboratory animals , china medical university 本实验应用pka激动剂camp及抑制剂pki显微注射入小鼠二一细胞期受精卵并观察卵细胞m期形态学变化及pka对mpf活性的影响以及cdc25c , cdcz电泳迁移率, cdcz的磷酸酪氨酸ptyrl及周期素b含量,为揭示pka在哺乳动物细胞周期调控机制,对生长、发育、癌变、死亡的研究提供理论依据。
Over - expression of yggg retarded the cell cycle , on the point after dna partition , resulting in accumulation of diploid as bacteria stop division and sequentially went to death . this appearance is similar to that of the era mutants , including the partially defective in era gtpase activity or the reduced in the synthesis of wild - type era which bacteria become arrested in the cycle at the predivisional two - cell stage 在荧光显微镜下细菌形态的变化,以及dapi染色和透射电子显微镜观察, yggg的表达与era突变(使era功能降低时)对细菌分裂的影响有类似之处,即细菌dna合成,子代dna分离后;分裂停滞,形成细菌繁殖受阻时, 2 - 4倍体的出现。
There was no significant difference between the fusion rates of reconstructed embryos . the cleavage rate of embryos reconstructed with c57bl / 6j oocytes was significant high than that of kunming albino , but the former only developed to 4 - cell stage ; the later could develop to blastocyts . it is implied that the oocytes of inbred mouse cannot support the long - term development of kunming es cell 两种重构胚的融合率之间没有显著差异( p 0 . 05 ) , c57bl 6j重构胚的卵裂率( 60 . 5 )明显高于昆明白小鼠( 33 . 7 ) ,但是前者只发育到4细胞期,而后者可以发育到桑椹期和囊胚期( 2 . 3 ) 。
