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 ...

Nucleotide synthesis—the production of the basic components of DNA and RNA—is essential for cell growth and division. In most ...

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, ...

Nucleotide synthesis-the production of the basic components of DNA and RNA-is essential for cell growth and division. In most animal cells, this process depends closely on properly functioning ...

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 ...

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, ...

Cellular findings show Telomir-Zn modulates intracellular metal balance linked to oxidative stress, mitochondrial ...

Stephen has degrees in science (Physics major) and arts (English Literature and the History and Philosophy of Science), as well as a Graduate Diploma in Science Communication. Stephen has degrees in ...

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 ...
