The structural and functional characteristics of mitochondria shape their role as signaling organelles, with far-reaching ...

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 ...

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 ...

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 ...

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, ...

Scientists led by a team at the Medical Research Council (MRC) Mitochondrial Biology Unit, University of Cambridge, have worked out how a molecular machine found in mitochondria—the “powerhouses” of ...
