Scientists have found DNA in the nucleus of brain cells, where it shouldn’t be. Bits of genes that typically reside in mitochondria insert themselves at unexpectedly high rates into brain cells’ ...

A mitochondrial DNA mutation passed down through the maternal line in some Venezuelan families has been linked to severe ...

Mitochondria release segments of mitochondrial DNA that can travel through pores of the nucleus and integrate into a cell's chromosomes (where the insertions are called NUMTs, for nuclear ...

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 ...

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

Researchers from the Mitochondrial Medicine Program at Children's Hospital of Philadelphia (CHOP) have better characterized a spectrum of what were classically considered discrete mitochondrial DNA ...

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

Normal metabolic activity produces reactive oxygen species (ROS) that, if not eliminated, can damage cellular components. As a result, ROS from overactive mitochondria are frequently cited as a source ...

The AHA recommended whole exome or whole genome sequencing as first-line diagnostic tools for mitochondrial diseases.

By Tarun Sai Lomte New evidence from Indian patients shows that severe COVID-19 is associated with distinct mitochondrial ...

New molecule halts mitochondrial DNA loss before it triggers inflammation. When environmental stress harms DNA, it can set off a cascade of failures linked to heart conditions, neurodegeneration and ...
