Recent research has shed light on the complex processes that cells use to maintain the quality of mitochondrial DNA (mtDNA) for inheritance across generations. These processes are particularly ...
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 ...
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 ...
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 act as energy factories in cells and have their own, separate DNA. Mutations to mitochondrial DNA (mtDNA) have been observed in cancer, but it has been unclear how these changes might ...
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 ...
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’ ...
