Researchers from Karolinska Institutet have discovered how mammalian cells prevent the gradual buildup of harmful mutations in mitochondrial DNA, the small but vital genome that powers every cell. The ...
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 ...
Researchers have identified a physical process called “mitochondrial pearling” that explains how cells keep their mitochondrial DNA evenly spaced and ready for inheritance during division. The finding ...
Organelles spit out DNA contaminated with damaging components, leading to the activation of inflammatory enzymes, mouse experiments show. Scientists found that, in the cells of ageing mice with kidney ...
