New research published in Nature Communications into hidden mutations in mitochondrial DNA has uncovered how high mutational levels coincide with later life and link to aging markers. Mitochondria are ...

When environmental stress harms DNA, it can set off a cascade of failures linked to heart conditions, neurodegeneration, and chronic inflammation. A new chemical tool developed at UC Riverside ...

The human genome is broadly classified into the genome residing in the cell nucleus (nuclear DNA) and the genome residing in the mitochondria (mitochondrial DNA: mtDNA). Mitochondria are cell ...

All living organisms are known to inherit genes, DNA sequences that contain instructions for producing specific proteins and ...

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 ...

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 ...

Mitochondria are widely known as the "powerhouse of the cell" because of their ability to generate energy in the body and convert nutrients from food. With such an essential job, mutations in ...
