Study identifies key factor in DNA damage associated with aging

Study identifies key factor in DNA damage associated with aging

March 3, 2017

There are many examples of DNA damage being associated with aging, but never has a reduction in DNA damage been shown to extend lifespan. Rochester research has made this connection, and identified an enzyme that can be targeted to reduce that damage.
