The applicability of mitochondrial nad6 sequences to studies of DNA and population variability in Lepidoptera was tested in four species of economically important moths and one of wild butterflies. The genetic information so obtained was compared to that of cox1 sequences for two species of Lepidoptera. nad6 primers appropriately amplified all the tested DNA targets, the generated data proving ...
The great phenotypic variability and the lack of diagnostic characters in the genus Pylaiella render the systematic study of this genus problematic. In this study, we investigated the diversity of Pylaiella littoralis along the Brittany (France) coast using a DNA barcoding multilocus approach with mitochondrial (cox1, nad1, and atp9) and chloroplastic (rbcL and atpB) markers associated with a p...
HUPRA syndrome is a rare autosomal recessive mitochondrial disorder caused by mutation in the SARS2 gene encoding seryl-tRNA synthetase (mtSerRS). It includes hyperuricemia, pulmonary hypertension, renal failure, and alkalosis. We present case report of boy aged 1 year 2 months with premature anemia, alkalosis diagnosed syndrome. This disease known to be progressive fatal. A genetic test reveal...
The amphidromous goby Sicyopterus japonicus is distributed throughout southern Taiwan and Japan. Larvae of this freshwater fish go through a long marine stage. This migratory mode influences population genetic structure. We examined the genetic diversity, population differentiation, and demographic history of S. japonicus based on the mitochondrial DNA control region. We identified 102 haplotyp...
Invasive species are classically thought to suffer from reduced within-population genetic variation compared to their native-range sources due to founder effects and population bottlenecks during introduction. Reduction in genetic variation in introduced species may limit population growth, increase the risk of extinction, and constrain adaptation, hindering the successful establishment and spr...
Salmonid fish have become ecological and research models of study in the field conservation genetics genomics. Over last decade, brown trout received a high level interest publications. The term Salmo trutta complex is used to indicate large number geographic forms present species trutta. In Europe, S. consists (based on mitochondrial DNA control region analysis) seven major evolutionary lineag...
OBJECTIVE Rare mitochondrial mutations cause neurologic disease, including ischemic stroke and MRI white matter changes. We investigated whether common mitochondrial genetic variants influence risk of sporadic ischemic stroke and, in patients with stroke, the volume of white matter hyperintensity (WMHV). METHODS In this multicenter, mitochondrial genome-wide association study (GWAS), 2284 isc...
There is abundant evidence to suggest that mitochondrial dysfunction is a main cause of insulin resistance and related cardiometabolic comorbidities. On the other hand, insulin resistance is one of the main characteristics of type 2 diabetes, obesity, and metabolic syndrome. Lipid and glucose metabolism require mitochondria to generate energy, and when O2 consumption is low due to inefficient n...
The mitochondrial genome, contained in the subcellular mitochondrial network, encodes a small number of peptides pivotal for cellular energy production. Mitochondrial genes are highly polymorphic and cataloguing existing variation is of interest for medical scientists involved in the identification of mutations causing mitochondrial dysfunction, as well as for population genetics studies. Human...
The high risk of metabolic disease traits in Polynesians may be partly explained by elevated prevalence of genetic variants involved in energy metabolism. The genetics of Polynesian populations has been shaped by island hoping migration events which have possibly favoured thrifty genes. The aim of this study was to sequence the mitochondrial genome in a group of Maoris in an effort to character...
