线粒体DNA修复系统相关酶的研究进展 Progress of Enzyme in Mitochondrial DNA Repair System
线粒体DNA DNA修复 酶 研究进展
2008/1/10
摘要线粒体DNA（mtDNA）编码线粒体电子传递系统的亚单位以及构建翻译机器所需的各种rRAN和tRNA。mtDNA编码的每一个亚单位都是线粒体完成正常的氧化磷酸化过程所必需的，因此，线粒体DNA的完整性对于生物体的生存十分重要。长期以来，人们一直认为线粒体中不存在DNA的修复。近年来在线粒体提取物中却检测到了一定数量的修复因子，提示线粒体中存在DNA的修复。主要对线粒体修复系统中相关酶的研究进展...
肝癌组织中线粒体DNA D-Loop区碱基变异与ROS水平Mutations in the D-Loop Region of Mitochondrial DNA and the ROS Level in the Tissue of Hepatocellular Carcinoma
线粒体DNA D-Loop 原发性肝癌 突变 活性氧类物质
2008/1/6
摘要
为了探讨ROS水平与突变的关系，对原发性肝癌线粒体DNA区的突变情况进行研究，同时对原发性肝癌患者组织细胞内ROS进行测定。选择20例原发性肝癌组织及其邻近的癌旁组织，用PCR方法将线粒体DNA D-Loop扩增后测序。组织内ROS的水平采用流式细胞技术测定。结果表明在20对原发性肝癌组织中存在8对mtDNA突变，突变率为40%,共发现突变位点53个，包括2个插入，11个缺失...
