Mitochondrial stress triggers a pro-survival response through epigenetic modifications of nuclear DNA
(Springer, 2019-04)
Mitochondrial dysfunction represents an important cellular stressor and when intense and persistent cells must unleash an adaptive response to prevent their extinction. Furthermore, mitochondria can induce nuclear ...
Sequence variation of mitochondrial DNA control region in North Central Venezuela
(Elsevier Ireland, 2012-09)
Horizontal gene transfers dominate the functional mitochondrial gene space of a holoparasitic plant
(Wiley Blackwell Publishing, Inc, 2021-02)
Although horizontal gene transfer (HGT) is common in angiosperm mitochondrial DNAs (mtDNAs), few cases of functional foreign genes have been identified. The one outstanding candidate for large-scale functional HGT is the ...
Patterns of population structure at microsatellite and mitochondrial DNA markers in the franciscana dolphin (Pontoporia blainvillei)
(John Wiley and Sons Ltd, 2016-12)
The franciscana dolphin, Pontorporia blainvillei, is an endemic cetacean of the Atlantic coast of South America. Its coastal distribution and restricted movement patterns make this species vulnerable to anthropogenic ...
Testosterone induces up-regulation of mitochondrial gene expression in murine C2C12 skeletal muscle cells accompanied by an increase of nuclear respiratory factor-1 and its downstream effectors
(Elsevier Ireland, 2020-01-15)
The reduction in muscle mass and strength with age, sarcopenia, is a prevalent condition among the elderly, linked to skeletal muscle dysfunction and cell apoptosis. We demonstrated that testosterone protects against ...
Genetic variation in populations from central Argentina based on mitochondrial and y chromosome DNA evidence
(Nature Publishing Group, 2018-04-29)
We present new data and analysis on the genetic variation of contemporary inhabitants of central Argentina, including a total of 812 unrelated individuals from 20 populations. Our goal was to bring new elements for ...
New Evidence of Ancient Mitochondrial DNA of the Southern Andes (Calchaquí Valleys, Northwest Argentina, 3,600–1,900 Years before Present)
(Wayne State University Press, 2019-09)
Genetic studies on pre-Hispanic populations of the Southern Andes have been increasing steadily in the last decade. Nevertheless, ancient DNA characterization of Formative Period archaeological human remains is particularly ...
First mitochondrial and nuclear DNA sequences of Lamanema chavezi (Nematoda: Molineidae) : novel findings to improve its identification in feces from South American camelids
(Elsevier, 2018-10-16)
Lamanema chavezi (Family Molineidae) is a parasitic nematode of South American camelids (SACs). A few studies have reported this parasite in SACs, mainly in domestic camelid species (llama and alpaca). Parasite identification ...
Epigenetic modification of liver mitochondrial DNA is associated with histological severity of nonalcoholic fatty liver disease
(B M J Publishing Group, 2013-09)
Objective & design: Nonalcoholic fatty liver disease (NAFLD) is a clinical condition that refers to progressive histological changes ranging from simple steatosis (SS) to nonalcoholic steatohepatitis (NASH). We evaluated ...
Substitution of human for horse urine disproves an accusation of doping
(Wiley Blackwell Publishing, Inc, 2008-09)
In order to detect switching and/or manipulation of samples, the owner of a stallion asked our lab to perform a DNA test on a positive doping urine sample. The objective was to compare the urine DNA profile versus blood ...
