1、胎儿生长受限子代大鼠与正常大鼠海马蛋白质组双向电泳图谱比较作者:黄谱,苟文丽,米阳,张瑞,孙云萍单位:1.西安交通大学医学院第一附属医院妇产科,陕西西安710061;2.陕西省妇幼保健院产科,陕西西安【摘要】目的比较胎儿生长受限(FGR)子代大鼠与正常大鼠海马蛋白质组双向电泳图谱的差异,探索蛋白质组学技术在FGR引起子代神经系统发育异常的研究中应用的可能性。方法建立SD大鼠的FGR模型,分离子代大鼠海马组织并提取总蛋白;进行双向电泳,比较FGR子代大鼠与正常大鼠海马组织的蛋白质表达差异。结果FGR子
2、代大鼠与正常大鼠海马组织双向电泳图谱分别检出647和626个蛋白点,对2张电泳图进行匹配后发现有18个蛋白点仅在FGR子代大鼠海马蛋白双向电泳图谱中表达,28个蛋白在2组大鼠海马组织中含量发生了3倍以上的变化,其中FGR组上调25个,下调3个。结论初步建立了FGR动物模型比较蛋白质组学的技术方法;FGR子代大鼠海马蛋白质组与正常大鼠存在明显差异,差异点的发现为深入研究FGR引起子代高级神经活动异常的发病机制提供了有益的线索。【关键词】胎儿生长受限;海马;学习记忆;双向电泳 Comparisonof
