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 ...

A new study finds that mitochondria in our brain cells frequently fling their DNA into the cells' nucleus, where the mitochondrial DNA integrates into chromosomes, possibly causing harm. As direct ...

Research led by the Max Planck Institute for Biology of Aging in Cologne reports that misincorporation of ribonucleotides into mitochondrial DNA (mtDNA) initiates an inflammatory cascade. Mitochondria ...

Inside every human cell, tiny mitochondria quietly convert nutrients into usable energy, keeping organs running and immune defenses primed. Now researchers have identified a previously unknown form of ...

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, ...

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, ...

Scraps of DNA discarded by our neurons' power units are being absorbed into our nuclear genome far more frequently than assumed, potentially putting our brains at greater risk of developing ...

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 ...

Stanford University-led researchers report that tumor cells hijack mitochondria from immune cells, reducing anti-tumor immune ...
