Mitochondrial transcription elongation factor maintains the balance between transcription and replication of mitochondrial DNA offering insights into potential treatments for mitochondrial disease and ...

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 ...

Researchers have discovered a key molecular process that may contribute to chronic inflammation as we age. If this process can be accurately targeted, it could unlock ways to stay healthier in our ...

The graphic shows images of a cell under mtDNA replication stress made using so-called Correlative Light and Electron Microscopy (for short: CLEM). The mitochondrial DNA (mtDNA, green) is ejected from ...

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, ...

Researchers identified a new, sticky form of mitochondrial DNA damage that builds up at dramatically higher levels than in nuclear DNA. These lesions disrupt energy production and activate ...

Mitochondrial DNA has long been treated as a workhorse record of cellular history, but new research suggests it also hides a subtle and previously overlooked form of damage. By uncovering this cryptic ...

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 ...

Back in the 19 th century, as the US grappled with the aftermath of the Civil War, Jesse James, leader of a notorious gang of outlaws, rose to prominence. He robbed banks and trains for over a decade ...

In most plants and animals, including humans, mitochondria are inherited exclusively, or nearly exclusively, from the mother.
