mtDNA variation in the chibcha ameridian huetar from Costa Rica
(1994)
The genetic variation in a Chibcha-speaking Amerindian tribe from lower Central America, the Huetar, was analyzed using nucleotide sequences of the hypervariable segments of the mitochondria! DNA (mtDNA) control region, ...
Acute psychological stress increases serum circulating cell-free mitochondrial DNA
(Elsevier Ltd, 2019)
Intrinsic biological mechanisms transduce psychological stress into physiological adaptation that requires energy, but the role of mitochondria and mitochondrial DNA (mtDNA) in this process has not been defined in humans. ...
Amerindian mtDNA haplogroups and celiac disease risk HLA haplotypes in mixed-blood Latin American patients
(Lippincott Williams and Wilkins, 2011)
Background and Objective: Risk haplotypes have been described in celiac disease (CD), but the influence of native genes on CD in Hispanic Americans is unknown. The aim of the study was to measure the frequency of Amerindian ...
Internucleotide correlations and nucleotide periodicity in Drosophila mtDNA: New evidence for panselective evolution
(Sociedad de Biología de Chile, 2010)
Archeological and mtDNA evidence for Tropical Lowland migrations during the Late Archaic / Formative in northern Chile

The role of mitochondrial DNA damage in the citotoxicity of reactive oxygen species
(SPRINGER/PLENUM PUBLISHERS, 2011)
Mitochondria contain their own genome, a small circular molecule of around 16.5 kbases. The mitochondrial DNA (mtDNA) encodes for only 13 polypeptides, but its integrity is essential for mitochondrial function, as all 13 ...
Determinação do polimorfismo das seqüências de DNA mitocondrial humano na população de Alagoas, Brasil

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 ...
