Mutations accumulated in mitochondrial DNA associated with aging were earlier believed to cause aging by decreasing the energy-producing function (mitochondrial respiratory function). In this study, ...

A clump of proteins seems to be in charge of the level of DNA repair that takes place in our bodies, determining how fast mutations accumulate in our cells over a lifetime – and might thus affect our ...

Two new studies from Karolinska Institutet in Sweden have investigated how mutations that occur in muscles and blood vessels over time can affect ageing. The studies, which are published in Nature ...
