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 ...

The human genome is broadly classified into the genome residing in the cell nucleus (nuclear DNA) and the genome residing in the mitochondria (mitochondrial DNA: mtDNA). Mitochondria are cell ...

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 ...

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 ...

A new collaborative study from Karolinska Institutet published in Science Advances shows that the levels of mitochondrial DNA (mtDNA) directly influence lung adenocarcinoma (LUAD) progression in mice.

Every cell in your body runs on mitochondria, the tiny power plants that convert food into usable fuel. For decades, the standard explanation for age-related energy loss was straightforward: ...

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 ...

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, ...
