Mitochondrial DNA Mutations, Pathogenicity and Inheritance
Mitochondria contain their own DNA (mtDNA), which codes for 13 proteins (all subunits of the respiratory chain complexes), 22 tRNAs and 2 rRNAs. Several mtDNA point mutations as well as deletions have been shown to be causative in well-defined mitochondrial disorders. A mixture of mutated and wild type mtDNA (heteroplasmy) is found in most of these disorders. Inheritance of mtDNA is maternal, a...
متن کاملA REPORT OF RAPID AND EFFICIENT METHOD FOR MITOCHONDRIAL DNA
Based on the similarity of prokaryotic DNA to that of mitochondrial DNA, a rapid and efficient method for DNA purification from mitochondrial extracts obtained from different sources, was carried out based on the modification method described by Marmur (1983) which resulted in a high degree of purity (A260/A280=2). In addition we have applied the same technique for the first time to purify...
متن کاملLymphocytes eject interferogenic mitochondrial DNA webs in response to CpG and non-CpG oligodeoxynucleotides of class C.
Circulating mitochondrial DNA (mtDNA) is receiving increasing attention as a danger-associated molecular pattern in conditions such as autoimmunity, cancer, and trauma. We report here that human lymphocytes [B cells, T cells, natural killer (NK) cells], monocytes, and neutrophils derived from healthy blood donors, as well as B cells from chronic lymphocytic leukemia patients, rapidly eject mtDN...
متن کامل1 mitochondrial DNA dysfunction by PAHs Mitochondrial
Background: Increased mitochondrial DNA copy number (mtDNAcn) is a biological response to mtDNA damage and dysfunction predictive of lung cancer risk. Polycyclic aromatic hydrocarbons (PAHs) are established lung carcinogens and may cause mitochondrial toxicity. Whether PAH exposure and PAHrelated nuclear DNA (nDNA) genotoxic effects are linked with increased mtDNAcn has never been evaluated. Me...
متن کاملMitochondrial DNA, mitochondrial dysfunction, and cardiac manifestations.
Mitochondria, are the powerhouses of cells, have their own DNA (mtDNA), regulate the transport of metabolites and ions, and impact cell physiology, survival, and death. Mitochondrial dysfunction, including impaired oxidative phosphorylation, preferentially affects heart function due to an imbalance of energy supply and demand. Recently, mitochondrial mutations and associated mitochondrial dysfu...
