SENESCENCE

Apolipoprotein E regulates chromatin stability and senescence

Apolipoprotein E (APOE) is an important regulator of lipid metabolism and is genetically associated with longevity and age-related diseases such as Alzheimer’s disease. However, the molecular mechanisms that link APOE and aging are incompletely understood. Now an article in Nature Aging reveals that nuclear APOE promotes senescence by destabilizing heterochromatin.
