research Myotonic Dystrophy—A Progeroid Disease?
Myotonic dystrophy may be classified as a segmental progeroid disorder.
research Abstracts
The document reports findings on genetic research, including ethical concerns about genome editing, improved diagnosis of mitochondrial mutations, solving inherited eye diseases, confirming gene roles in epilepsy, linking a gene to aneurysms, and identifying genes associated with age-related macular degeneration.
research Quantifying effects of aging across structures of the mouse auditory system, with in-vitro brain slice preparations
Chronological age affects the mouse auditory cortex more than hearing loss, and the brain may be less sensitive to mitochondrial dysfunction.
research Highlights from the Literature
Apoptosis, not oxidative stress, is linked to aging in mice with mtDNA mutations.
research Transient mitochondrial DNA double strand breaks in mice cause accelerated aging phenotypes in a ROS-dependent but p53/p21-independent manner
Damaging mitochondrial DNA in mice speeds up aging due to increased reactive oxygen species, not through the p53/p21 pathway.
research Defects in mitochondrial DNA replication and oxidative damage in muscle of mtDNA mutator mice
Defective mitochondrial DNA replication causes aging symptoms and increased oxidative damage in mice.
research Mitochondrial DNA Damage, Oxidative Stress, and Atherosclerosis
Improving mitochondrial health may better treat atherosclerosis than antioxidants.
research Quantitation of human mitochondrial DNA and whole mtGenomes sequencing of fingernail/hair shaft samples
Mitochondrial DNA from nails and hair can be effectively analyzed for forensic use.
research Epithelial loss of mitochondrial oxidative phosphorylation leads to disturbed enamel and impaired dentin matrix formation in postnatal developed mouse incisor
Mitochondrial problems in tooth cells lead to bad enamel and dentin development in mice.
