Researchers have pinned down a particular genetic variation that plays a role in defining whether you look older or younger than your years.
We can't halt the aging process, but studies suggest it may be possible to reverse the effects. We investigate such research and look at what we can do to promote healthy aging.
While there are well-established mouse models to identify cancer-causing agents, similar models are not available to readily test and identify age-promoting agents. Recently, a mouse strain (p16LUC mice) was developed that can be used to evaluate the transcription of p16INK4, which is increasingly expressed during aging and in age-associated diseases.
