Manipulating mitochondrial DNA heteroplasmy by a mitochondrially targeted restriction endonuclease.
Mutations in the mitochondrial DNA (mtDNA) can cause a variety of human diseases. In most cases, such mutations are heteroplasmic (i.e. mutated and wild-type mtDNA coexist) and a small percentage of wild-type sequences can have a strong protective effect against a metabolic defect. Because a genetic approach to correct mtDNA mutations is not currently available, the ability to modulate heteropl...
متن کاملPhylogenetic Invariants for Metazoan Mitochondrial Genome Evolution.
The method of phylogenetic invariants was developed to apply to aligned sequence data generated, according to a stochastic substitution model, for N species related through an unknown phylogenetic tree. The invariants are functions of the probabilities of the observable N-tuples, which are identically zero, over all choices of branch length, for some trees. Evaluating the invariants associated ...
متن کاملRestriction enzyme analysis of the mitochondrial genome in mitochondrial myopathy.
The mitochondrial myopathies are a heterogeneous group of disorders some of which may be caused by mutations in the mitochondrial genome. Mitochondrial DNA from 10 patients with mitochondrial myopathy and their mothers was analysed using five restriction enzymes and 11 mitochondrial probes in bacteriophage M13. No abnormalities were found in seven out of the 10 patients. Polymorphisms which hav...
متن کاملManipulating the Mitochondrial Genome To Enhance Cattle Embryo Development
The mixing of mitochondrial DNA (mtDNA) from the donor cell and the recipient oocyte in embryos and offspring derived from somatic cell nuclear transfer (SCNT) compromises genetic integrity and affects embryo development. We set out to generate SCNT embryos that inherited their mtDNA from the recipient oocyte only, as is the case following natural conception. While SCNT blastocysts produced fro...
متن کاملMITOS: improved de novo metazoan mitochondrial genome annotation.
About 2000 completely sequenced mitochondrial genomes are available from the NCBI RefSeq data base together with manually curated annotations of their protein-coding genes, rRNAs, and tRNAs. This annotation information, which has accumulated over two decades, has been obtained with a diverse set of computational tools and annotation strategies. Despite all efforts of manual curation it is still...
