Autosomal disorders of mitochondrial DNA maintenance.
Mitochondrial DNA (mtDNA) is maternally inherited. After birth, secondary mtDNA defects can arise. MtDNA depletion is a reduction in the amount of mtDNA in particular tissues. Multiple deletions of mtDNA accumulate as somatic mutations in mainly postmitotic tissues. These disorders of mtDNA maintenance frequently show Mendelian inheritance. Positional cloning has identified several genes involv...
متن کاملMitochondrial DNA-related disorders.
Mitochondrial diseases are a group of disorders due to a mitochondrial respiratory chain deficiency. They may depend on mitochondrial genome (mtDNA-related disorders) as well as on a nuclear genome defect (nDNA-related disorders). mtDNA-related disorders encompass an increasing number of clinical pictures associated with more than 250 different provisional or confirmed pathogenic changes in mtD...
متن کاملMitochondrial DNA maintenance and bioenergetics.
Oxidative phosphorylation requires assembly of the protein products of both mitochondrial and of nuclear genomes into functional respiratory complexes. Cellular respiration can be compromised when mitochondrial DNA (mtDNA) sequences are corrupted. Oxidative damage resulting from reactive oxygen species (ROS) produced during respiration is probably a major source of mitochondrial genomic instabi...
متن کاملprospects for antifibrotic therapy
antifibrotic therapies should preferentially be targeted to the activated hepatic mesenchymal cells. those cells resemble wound healing myofibroblasts and synthesize an excess of extracellular matrix (ecm) proteins. they derive from quiescent hepatic stellate cells (hsc) and portal/perivascular (myo-) fibroblasts (mf). whereas various agents have been shown to inhibit hsc/mf proliferation and c...
متن کاملStem Cell Therapy for Neonatal Disorders: Prospects and Challenges
Despite recent advances in neonatal medicine, neonatal disorders, such as bronchopulmonary dysplasia and intraventricular hemorrhage in preterm neonates and hypoxic ischemic encephalopathy in term neonates, remain major causes of mortality and morbidities. Promising preclinical research results suggest that stem cell therapies represent the next breakthrough in the treatment of currently intrac...
