Protocol for quantifying miRNA trafficking across the endosomal membrane

open access: yesFEBS Open Bio, EarlyView.
An in vitro protocol measures miRNA uptake into endosomes isolated from mammalian cell extracts, which are free of subcellular contaminants. Performed at 37 °C in the presence of ATP, it ensures the import of single‐stranded miRNA into the endosomal lumen.

Mitochondrial DNA mitochondrial dysfunction and cardiac manifestations

open access: yesFrontiers in Bioscience, 2016
Mitochondria, the powerhouses of cells, have their own DNA (mtDNA). They regulate the transport of metabolites and ions, which determine cell physiology, survival, and death. Mitochondrial dysfunction, including impaired oxidative phosphorylation, preferentially affects heart function via imbalance of energy supply and demand.

Comparative assessment of crystallographic and cryo‐EM models in the Protein Data Bank

open access: yesFEBS Open Bio, EarlyView.
Raw data obtained by X‐ray crystallography or cryo‐EM result in experimental maps, ultimately fitted by atomic models. Although the physical principles are different, the final results can be viewed, compared, and evaluated in the same way. With cryogenic electron microscopy (cryo‐EM) on track to surpass X‐ray crystallography as the preferred method ...

RETRACTED: MtDNA polymorphism analyses in the Chinese Mongolian group: Efficiency evaluation and further matrilineal genetic structure exploration

open access: yesMolecular Genetics & Genomic Medicine, 2019
Background Profiling of mitochondrial DNA is surely to provide valuable investigative clues for forensic cases involving highly degraded specimens or complex maternal lineage kinship determination.

Hyperoxia activates ATM independent from mitochondrial ROS and dysfunction

open access: yesRedox Biology, 2015
High levels of oxygen (hyperoxia) are often used to treat individuals with respiratory distress, yet prolonged hyperoxia causes mitochondrial dysfunction and excessive reactive oxygen species (ROS) that can damage molecules such as DNA.

BCG vaccination potentiates oxidative phosphorylation in neonatal myeloid‐derived suppressor cells

open access: yesFEBS Open Bio, EarlyView.
BCG vaccination enhances oxidative phosphorylation in neonatal MDSCs, impairing their immunosuppressive function. It upregulates electron transport chain genes and mitochondrial activity, increasing ATP and oxygen consumption. Pharmacological OXPHOS inhibition partially restores suppressive capacity, confirming causality.

Mitochondrial DNA editing: Key to the treatment of neurodegenerative diseases

open access: yesGenes and Diseases
Neuronal death is associated with mitochondrial dysfunction caused by mutations in mitochondrial DNA. Mitochondrial DNA becomes damaged when processes such as replication, repair, and nucleotide synthesis are compromised.

IGF2 knockout reduces but does not abolish osteosarcoma growth in vitro and in vivo

open access: yesFEBS Open Bio, EarlyView.
To test whether endogenous IGF2 promotes osteosarcoma growth, IGF2 was knocked out in Saos2 cells via CRISPR‐Cas9. KO cells showed reduced proliferation in vitro, and knockout xenografts in mice reached only ~25% of wild‐type tumor volume. Insulin‐like growth factor 2 (IGF2) is implicated in osteosarcoma, but direct functional evidence of its role is ...

Mitochondrial DNA in CSF distinguishes LRRK2 from idiopathic Parkinson's disease

open access: yesNeurobiology of Disease, 2016
Mitochondrial DNA regulates mitochondrial function which is altered in both idiopathic and familial forms of Parkinson's disease. To investigate whether these two disease forms exhibit an altered regulation of mitochondrial DNA we measured cell free ...

Mitochondrial DNA and Genetic Disease [PDF]

open access: yesDevelopmental Medicine & Child Neurology, 1988
AbstractSince the human mitochondrial genome was characterised and sequenced in 1981(1), it has been viewed as the likely site of genetic diseases showing a maternal inheritance pattern and associated with defects of the respiratory chain, such as the mitochondrial myopathies (MMs)†(2).
