Ergosterol reduction impairs mitochondrial DNA maintenance in S. cerevisiae [PDF]

open access: yes, 2019
Sterols are essential lipids, involved in many biological processes. In Saccharomyces cerevisiae, the enzymes of the ergosterol biosynthetic pathway (Erg proteins) are localized in different cellular compartments.

Rapid evolution of animal mitochondrial DNA.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1979
Mitochondrial DNA was purified from four species of higher primates (Guinea baboon, rhesus macaque, guenon, and human) and digested with 11 restriction endonucleases. A cleavage map was constructed for the mitochondrial DNA of each species. Comparison of

Plasma Mitochondrial DNA Level is a Prognostic Marker in Peritoneal Dialysis Patients

open access: yesKidney & Blood Pressure Research, 2016
Background/Aims: Circulating bacterial DNA fragment is related to systemic inflammatory state in peritoneal dialysis (PD) patients. We hypothesize that circulating mitochondrial DNA, which has a similar structure with bacterial DNA, correlates with ...

Mitochondrial DNA and Disease [PDF]

open access: yesAnnals of Medicine, 1997
Mitochondrial diseases are a group of disorders characterized by morphological or functional defects of the mitochondria, the organelles producing most of our cellular energy. As the only extranuclear site carrying genetic information, the mitochondria add an important chapter into the inheritance patterns of genetic diseases. Mitochondrial DNA (mtDNA)

Taurine promotes glucagon‐like peptide‐1 secretion in enteroendocrine L cells

open access: yesFEBS Letters, EarlyView.
Taurine, a sulfur‐containing amino acid, is likely taken up by enteroendocrine L cells via the taurine transporter. This process increases the levels of cytosolic ATP. The increase in intracellular Ca2+ concentrations and glucagon‐like peptide‐1 secretion through membrane depolarization is caused by the closure of ATP‐sensitive potassium channels ...

Quantification of DNA Products Using Ion-Pair Reverse Phase Liquid Chromatography [PDF]

open access: yes, 2017
The transcription of DNA via RNA polymerases is a fundamental process in cellular systems. In eukaryotic cells, we observe transcription in the nucleus (via genomic DNA) as well as in the mitochondria (via mitochondrial DNA).

Extensive Structural Variations Between Mitochondrial Genomes of CMS and Normal Peppers (Capsicum Annuum L.) Revealed by Complete Nucleotide Sequencing [PDF]

open access: yes, 2014
Cytoplasmic male sterility (CMS) is an inability to produce functional pollen that is caused by mutation of the mitochondrial genome. Comparative analyses of mitochondrial genomes of lines with and without CMS in several species have revealed structural ...

Commentary of "The Use of Mitochondrial Replacement in IVF: A Call for Expansion"

open access: yesVoices in Bioethics, 2014
by Lillian Ringel • Briana’s op-ed calling for expansion of mitochondrial DNA replacement in IVF was an interesting read.  She starts her op-ed with a description of what mitochondrial DNA is, and though it may seem rudimentary to some, since I have a

TYMP Variants Result in Late-Onset Mitochondrial Myopathy With Altered Muscle Mitochondrial DNA Homeostasis

open access: yesFrontiers in Genetics, 2020
Biallelic TYMP variants result in the mitochondrial neurogastrointestinal encephalomyopathy (MNGIE), a juvenile-onset disorder with progressive course and fatal outcome. Milder late-onset (>40 years) form has been rarely described.

Mitochondrial network state scales mtDNA genetic dynamics [PDF]

open access: yes, 2018
Mitochondrial DNA (mtDNA) mutations cause severe congenital diseases but may also be associated with healthy aging. MtDNA is stochastically replicated and degraded, and exists within organelles which undergo dynamic fusion and fission. The role of the resulting mitochondrial networks in the time evolution of the cellular proportion of mutated mtDNA ...
