In Aging Cell, researchers have reported that chromatin demethylation allows SASP compounds to be more easily expressed. Chromatin and gene expression Why We Age: Cellular SenescenceAs your body ages, more of your cells become senescent. Senescent cells do not divide or support the tissues of which they are part; instead, they emit potentially harmful chemical...

Researchers have analyzed molecular patterns from different tissues obtained from over 700 people and learned that smoking acts as an aging accelerator and involves molecular changes in tissues beyond those directly exposed to cigarette smoke [1]. Millions of preventable deaths Despite campaigns aimed at the reduction of tobacco smoking, it is still a very common...

In Aging Cell, researchers have found that exposing ordinary Black 6 mice to a more natural environment accelerates rather than slows the aging of their livers. When natural doesn't mean better It is a well-known fact that laboratory animals live in controlled conditions beyond that of wild animals or even most pets. Temperature and food...

Using a mouse model, researchers from UCSF have found that the genes that become activated on the silent X chromosome might explain some sex-dependent differences in cognitive abilities during aging [1]. XX and XY It is widely known that women live longer than men [2]. Women also show differences in cognitive aging [3]. "In typical...

A recent study reported significant associations between increased heat days and accelerated epigenetic aging [1]. Heat alters DNA While warm summer days on the beach are pleasant, extreme heat is not as enjoyable, especially in daily life. It is also not healthy, since extreme heat has been linked to cardiovascular diseases and death [2, 3]....

In the Nature publication Signal Transduction and Targeted Therapy, researchers have described how glibenclamide, a drug used to treat type 2 diabetes, partially reverses epigenetic alterations and fights cellular senescence in mice. A system tightly tied together This paper begins with a discussion of the relationship between epigenetic alterations and cellular senescence. The histone H3K4me3...
