A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how ...

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 UCLA-led study has provided an unprecedented look at how gene regulation evolves during human brain development, showing how the 3D structure of chromatin — DNA and proteins — plays a critical role.

One small compartment inside the nucleus has come into focus with regards to aging: the nucleolus. Its main job is simple and ...

DNA methylation is a key epigenome component that helps dictate how genes are expressed, contributing to normal cell and tissue differentiation during development, as well as the process of biological ...
