DNA double strand breaks (DSB) are among the most lethal forms of DNA damage and can occur as a result of ionizing radiation (IR), radiomimetic agents, endogenous DNA-damaging agents, etc. If left unr...
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...
云南保山猪线粒体DNA D-loop区序列初步分析Primary Analysis of Mitochondrial DNA D-loop Region Sequence in Baoshan Pig
保山猪 线粒体DNA D-loop 高变区I 遗传多样性
2007/12/31
摘要
摘要:为了解云南保山猪(Baoshan pig)的遗传多样性及其遗传背景,我们测定了19个个体线粒体DNA D-loop高变区I 15 363~15 801片段序列438 bp。检测到10种单倍型,包括8个多态位点,其中5次T/C转换、1次G/A转换、1次G/C颠换和1次A/T颠换,其A、T、G、C碱基的平均含量分别为35.4%、26.9%、13.2%和24.5%,A+T含量(62.3%)...
摘要
通过PCR克隆的方法,获得了分别来自二倍体长穗偃麦草的E基因组和四倍体长穗偃麦草的E1基因组的4个高分子量麦谷蛋白亚基(HMW-GS)基因启动子的部分序列。序列分析表明,它们之间的同源性较高,两个x型亚基启动子序列之间只有1个碱基的差异,而两个y型亚基启动子序列完全相同, x和y型亚基启动子序列之间的长度和部分碱基位点都有差异。推测四倍体长穗偃麦草中的E1基因组可能起源于二倍体的E基因组。...
