Mitochondrial DNA depletion syndrome (MTDPS) is a rare genetic disorder characterized by a marked decrease in mitochondrial DNA (mtDNA). This condition can cause symptoms including muscle weakness, ...

The tiny little powerhouses of our cells, the mitochondria, are unique among organelles because they carry their own tiny ...

A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress. The findings of the UC ...

Mitochondria are often described as the cell’s power plants, but a wave of new research suggests their genetic material may also hide a critical, underappreciated source of disease. Scientists are ...

Mitochondria act as energy factories in cells and have their own, separate DNA. Mutations to mitochondrial DNA (mtDNA) have been observed in cancer, but it has been unclear how these changes might ...

Researchers from Karolinska Institutet have discovered how mammalian cells prevent the gradual buildup of harmful mutations in mitochondrial DNA, the small but vital genome that powers every cell. The ...

Mutations accumulated in mitochondrial DNA associated with aging were earlier believed to cause aging by decreasing the energy-producing function (mitochondrial respiratory function). In this study, ...

In a step toward treating mitochondrial diseases, researchers at the University Medical Center Utrecht and their colleagues have used mitochondrial base editing (mtBE) to successfully edit harmful ...

For decades, the dream of fixing harmful mutations in mitochondrial DNA felt out of reach. Scientists have long known these mutations cause serious diseases that pass down only through mothers. They ...

Scientists can protect children from being born with certain devastating genetic disorders by creating "three-parent" babies, according to the results of a landmark study released Wednesday. British ...
