Mitochondrial genotype modulates mtDNA copy number and organismal phenotype in Drosophila
(Elsevier B.V., 2017-05-01)
We evaluated the role of natural mitochondrial DNA (mtDNA) variation on mtDNA copy number, biochemical features and life history traits in Drosophila cybrid strains. We demonstrate the effects of both coding region and ...
Embryo Mitochondrial DNA Depletion Is Reversed During Early Embryogenesis in Cattle
(SOC STUDY REPRODUCTION, 2010)
The extensive replication of mitochondria during oogenesis and the wide variability in mitochondrial DNA ( mtDNA) copy numbers present in fully grown oocytes indicate that mtDNA amount may play an important role during ...
Plasma lactate and leukocyte mitochondrial DNA copy number as biomarkers of insulin sensitivity in non-diabetic women
(2019)
High plasma lactate levels have been associated with reduced mitochondrial respiratory capacity and increased type 2 diabetes risk, while mitochondrial DNA (mtDNA) copy number has been proposed as a biomarker of mitochondrial ...
Lethal Interaction of Nuclear and Mitochondrial Genotypes in Drosophila melanogaster
(Genetics Society America, 2019-07-01)
Drosophila melanogaster, like most animal species, displays considerable genetic variation in both nuclear and mitochondrial DNA (mtDNA). Here we tested whether any of four natural mtDNA variants was able to modify the ...
Maternal blood mitochondrial DNA copy number and placental abruption risk: results from a preliminary study
(e-Century Publishing, 2013-06-25)
Oxidative stress and impaired placental function – pathways implicated in the pathogenesis of placental abruption – have their origins extending to mitochondrial dysfunction. To the best of our knowledge, there are no ...
Structural rearrangements in the mitochondrial genome of Drosophila melanogaster induced by elevated levels of the replicative DNA helicase
(Oxford Univ Press, 2018-04-06)
Pathological conditions impairing functions of mitochondria often lead to compensatory upregulation of the mitochondrial DNA (mtDNA) replisome machinery, and the replicative DNA helicase appears to be a key factor in ...
Mitochondrial DNA deletions detected by Multiplex Ligation-dependent Probe Amplification
(Informa Healthcare, 2015-06)
The genetic diagnosis algorithm for mitochondrial (mt) diseases starts looking for deletions and common mutations in mtDNA. MtDNA's special features, such as large and variable genome copies, heteroplasmy, polymorphisms, ...
