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

How One Tiny Cellular Structure Holds the Key to Better Health & Longevity — and How You Can Harness It ...

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 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 ...

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 ...

As tough as medieval chainmail armor and as soft as a contact lens. This material is not taken from science fiction, it is a natural structure made of thousands of DNA circles interlinked with each ...

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 ...

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, ...

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 ...
