Mitochondrial DNA Damage and Diseases
Various endogenous and environmental factors can cause mitochondrial DNA (mtDNA) damage. One of the reasons for enhanced mtDNA damage could be its proximity to the source of oxidants, and lack of histone-like protective proteins. Moreover, mitochondria contain inadequate DNA repair pathways, and, diminished DNA repair capacity may be one of the factors responsible for high mutation frequency o...

متن کاملMitochondrial DNA damage and atherosclerosis.
Mitochondria are often regarded as the cellular powerhouses through their ability to generate ATP, the universal fuel for metabolic processes. However, in recent years mitochondria have been recognised as critical regulators of cell death, inflammation, metabolism, and the generation of reactive oxygen species (ROS). Thus, mitochondrial dysfunction directly promotes cell death, inflammation, an...
متن کاملMitochondrial DNA damage triggers mitochondrial-superoxide generation and apoptosis.
Recently, it has become apparent that mitochondrial DNA (mtDNA) damage can rapidly initiate apoptosis independent of mutations, although the mechanism involved remains unclear. To elucidate this mechanism, angiotensin II-mediated apoptosis was studied in cells that were transduced with a lentiviral vector to overexpress the DNA repair enzyme 8-oxoguanine glycosylase or were treated with inhibit...
