线粒体DNA(mtDNA)重排是许多疾病发展中的关键事件。对受重排影响的mtDNA区域(即断裂点)的研究可以导致关于重排机制的重要发现,并可以提供关于线粒体疾病原因的重要线索。在这里,我们提出了线粒体DNA断裂点数据库(MitoBreak; http://mitobreak.portugene.com),这是一个免费的,可通过网络访问的完整的断裂点列表,来自三类体细胞mtDNA重排:环状缺失(缺失),环状部分重复(重复)和线性mtDNA。目前,MitoBreak包含来自7个物种(智人、小家鼠、褐家鼠、猕猴、黑腹果蝇、秀丽隐杆线虫和鹅柄孢菌)的>1400个mtDNA重排以及从近400篇出版物中收集的相关表型信息。该数据库允许研究人员通过用户友好的界面对完整或部分数据集进行多种类型的数据分析。它还允许下载精选数据和提交新的mtDNA重排。对于每个报告的病例,MitoBreak还记录了精确的断点位置,连接序列,疾病或相关症状以及相关出版物的链接,为研究mtDNA结构改变的原因和后果提供了有用的资源。
Mitochondrial DNA (mtDNA) rearrangements are key events in the development of many diseases. Investigations of mtDNA regions affected by rearrangements (i.e. breakpoints) can lead to important discoveries about rearrangement mechanisms and can offer important clues about the causes of mitochondrial diseases. Here, we present the mitochondrial DNA breakpoints database (MitoBreak; http://mitobreak.portugene.com), a free, web-accessible comprehensive list of breakpoints from three classes of somatic mtDNA rearrangements: circular deleted (deletions), circular partially duplicated (duplications) and linear mtDNAs. Currently, MitoBreak contains >1400 mtDNA rearrangements from seven species (Homo sapiens, Mus musculus, Rattus norvegicus, Macaca mulatta, Drosophila melanogaster, Caenorhabditis elegans and Podospora anserina) and their associated phenotypic information collected from nearly 400 publications. The database allows researchers to perform multiple types of data analyses through user-friendly interfaces with full or partial datasets. It also permits the download of curated data and the submission of new mtDNA rearrangements. For each reported case, MitoBreak also documents the precise breakpoint positions, junction sequences, disease or associated symptoms and links to the related publications, providing a useful resource to study the causes and consequences of mtDNA structural alterations.
