项目摘要

1.We made the knock-out vector (H protein gene-KO) that carry mouse H protein 5'-genomic DNA, loxP, exon1, loxP, pGK-neo, loxP, mouse H protein 3'-genomic DNA in this sequence.2.We introduced the linearized knock-out vector into mouse ES cells and got 11 cell lines of ES cells that have undergone homologous recombination between the ES genome and knock-out vector.3.Next, we microinjected recombinated ES cells to C57 Black mouse blastocysts and obtained 7 male chimeras, 3 of them have undergone germ-line transmission of the mutated allele.4.We then mated F1 mice with Cre recombinase-expressing transgenic mice. In the next generation, excision of exon1 DNA sequence was confirmed by genome PCR and Southern blot analyses.5.To determine whether the H protein expression is downregulated in the tissues of H protein +/-mice, we performed Western blot analysis using anti-H protein rabbit polyclonal antibody. Western blot analysis indicated that the H protein is decreased to 50% in the brains of +/-mice as compared to +/+ mice.6.We mated males and females of H protein +/-mice and analyzed the genotypes of newborn pups and embryos. PCR analyses have clearly shown that homozygous H protein knockout mice can not be born alive or even develop to E14.7.In the present study, we obtained the H protein +/-mice that have reduced (50%) levels of H protein and showed that H protein is essential for normal development and survival of mouse embryos. By using Cre/lox P system, we will be able to know the unknown functions of H protein in vivo.

2.将线性化的基因敲除载体导入小鼠ES细胞，获得了11个ES细胞系，它们在ES基因组和敲除载体之间发生了同源重组。3.将重组ES细胞显微注射到C57黑鼠囊胚中，获得了7个雄性嵌合体。将突变的等位基因进行种系传递。4.用Cre重组酶转基因小鼠与F1小鼠交配。5.利用抗H蛋白兔多克隆抗体进行Western印迹分析，以确定H蛋白在H蛋白+/-小鼠组织中的表达是否下调。Western印迹分析表明，与+/+小鼠相比，+/-小鼠大脑中的H蛋白减少到50%。6.我们对H蛋白+/-小鼠的雄性和雌性进行交配，并对新生幼鼠和胚胎进行了基因分型。PCR分析表明，纯合子H蛋白基因敲除小鼠不能活着出生，甚至不能发育到E14.7。在本研究中，我们获得了H蛋白水平降低(50%)的H蛋白+/-小鼠，表明H蛋白对小鼠胚胎的正常发育和存活是必不可少的。通过使用Cre/lox P系统，我们将能够了解H蛋白在体内的未知功能。
