Enhanced tumorigenicity by mitochondrial DNA mild mutations
To understand how mitochondria are involved in malignant transformation we have generated a collection of transmitochondrial cybrid cell lines on the same nuclear background (143B) but with mutant mitochondrial DNA (mtDNA) variants with different degrees of pathogenicity. These include the severe mutation in the tRNALys gene, m.8363G>A, and the three milder yet prevalent Leber's hereditary opti...
متن کاملMitochondrial 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 کاملMitochondrial DNA Mutations in Cancer
Mitochondrial defects have been associated with severe neurodegenerative disorders [2], and, more recently, with primary hereditary neoplasias. Germline heterozygote mutations in the nucleus-encoded mitochondrial succinate dehydrogenase (SDH) subunits—a tricarboxylic acid cycle (TCA) enzyme, which is also part of the respiratory chain—cause inherited pheochromocytomas and paragangliomas. Mutati...
متن کاملThe mitochondrial DNA mutations associated with cardiac arrhythmia investigated in an LQTS family
Objective(s): As mitochondrial oxidative stress is probably entailed in ATP production, a candidate modifier factor for the long QT syndrome (LQTS) could be mitochondrial DNA (mtDNA). It has been notified that ion channels' activities in cardiomyocytes are sensitive to the ATP level. Materials and Methods: The sample of the research was an Iranian family with LQTS for mutations by PCR-SSCP and...
متن کاملMitochondrial DNA mutations in Parkinson's disease brain
Dear Editors, We read with interest the publication by Wei et al., Mitochondrial DNA Point Mutations and Relative Copy Number in 1363 Disease and Control Human Brains, Acta Neuropathol Commun. 2017; 5: 13 [4]. We disagree with the authors’ conclusion that their data indicate that, “single nucleotide variants of mtDNA are unlikely to play a major role in the pathogenesis of these neurodegenerati...
